Background Why do we need to conduct a food consumption and nutrition survey? The current data used in nutrition circles in the country are often fairly old and drawn from different surveys of different methodologies and techniques, or notably focused on specific aspects of nutrition. Some of such data include the Nigeria Demographic and Health Survey (NDHS 1990>, the Participatory Information Collection (PIC 1993), the Opportunities for Micronutrient Interventions (OMNI 1993), the Multi-Cluster Indicator Survey (MICS 1995), and the Benchmark Survey (BMS 1996) reports, among others. Even the most recent findings of MICS (1999), the Baby Friendly Hospital Initiative Impact Evaluation (BFHI 1999), and the Health Survey (NDHS 1999) fell short of covering all the relevant aspects of nutrition. The shortcomings of some of these surveys are that they had objectives other than nutrition but included some of the nutrition indicators as secondary foci. Others fell short technically because of the limitations posed by the need to combine biochemical techniques with participatory social sector and scientific methods in eliciting holistic nutrition data. Generally, most of these surveys which attempted to address nutrition indicators used classical techniques that had little or no community participation : a key aspect of current techniques for eliciting information and feedback to beneficiaries as active participants in the development process. Further, the changing socioeconomic conditions have not only dimmed the relevance of these information sources but also made some of them obsolete and at times misleading as programming and planning tools. It is therefore pertinent to undertake a holistic national survey to generate, in a participatory manner, very current data in all aspects of nutrition covering food security, health and healthy environment in nutrition and care for both planning and programming in Nigeria. The information should also be useful to all agencies with primary and secondary mandates and foci in nutrition. Goal The overall goal objective of the Food Consumption and Nutrition Survey (FCNS) is to determine the nutritional status and nutrient intakes of the rural and urban populations in Nigeria. Purpose Assess the extent and nature of food insecurity in Nigeria. Conduct food consumption survey and undertake anthropometric and a biochemical assessment to determine the nutritional status of women and children under 5 years old.
Collect information and awareness from households on home health practices and food processing . Specific Objectives Determine the nature and extent of food insecurity and actual food consumption patterns. Using quantitative methodologies, assess the nutritional status of women and children . Determine the micronutrients (vitamin A, iron, zinc, and iodine) status of women and children from food intake and biochemical indices. Elicit from household and communities information on home health practices, and food processing (including food fortification). Use the results to design appropriate intervention strategies to address the identified problems.
Scope of the survey The scope of the survey is national, covering 12 states, representing a third of the total states of the federation, 72 local government areas (LGAs), 216 enumeration areas (EAs), and 30 households from each EA
2
Introduction and overview of the survey Introduction The success of a nutrition survey is hinged on a clear understanding of the philosophy of the survey and the nature of the data to be collected and the way it should be collected. As an interviewer on the Food Consumption and Nutrition Survey (FCNS), you have a very important role in the success of the survey. It is therefore very important that you study this document and obtain a clear understanding of the information contained in it. It is also expected that you will evaluate field procedures and respondents and suggest changes and improvement for the main study. We look forward to your participation in this important study. Food Consumption and Nutrition Survey: 2001 is a national study for which data on the nature and extent of food security, food intakes, anthropometric and biochemical parameters will be collected and used to determine the nutritional status of women and children in rural and urban populations. A critical component of FCNS is the food intake portion of the 24-hour dietary recall questionnaire. Respondents are requested to recall what they ate the day before the interview. A guidebook called the food instruction booklet (RB) accompanying this manual is used as aid to interviewers in obtaining detail information on both the types of food eaten and the amount. Examples of probes that can be used to elicit the required infomnation are in FIB. The data collection instrument (questionnaire) covers a wide variety of topics. For example, the household (HH) composition has questions covering the names of persons who regularly live in HH; their sex, age, relation to household head, education, eligibility to provide information or/and sample. In addition, socio economic characteristics of HH are covered. Other topics included are food security, household food consumption expenditure and food-related coping strategies, assessment of nutritional status, and health and care issues. Beneficiaries The primary beneficiaries of this survey are children under 5 years, pregnant women, and nursing mothers in Nigeria. Through this survey, information on their rlutritional status will be available. This information will enable policymakers, researchers, and developmental agencies to formulate poliCies and sustai nable interventions that will improve the nutritional status of these target groups. Pilot study For a study of this magnitude and importance, it is essential to test all aspects of the materials and procedures to be used before the main study begins. The pilot study
3
tests the use of the questionnaire, procedures designed for use in the main study, and logistics. The results of the pilot study and the experience of using these tools and procedures will enable us to modify and improve them for the main study. The pilot study will be conducted in each zone. One LGA and one EA will be selected in each zone. Ten households will be interviewed in each selected EA making a total of 40 households. All parameters will be taken during the pilot study.
4
Purpose of the manual Purpose This manual will be used for the pilot study and the Nigeria Food Consumption and Nutrition Survey 2001 . Upon completion of the pilot study, changes to the manual will be made accordingly. The purpose of this interviewer's manual is to: Familiarize the interviewer with the philosophy and objectives of the Nigeria Food Consumption and Nutrition Survey 2001. Provide explanations for implicit terminology. Guide the interviewer to adecuately prepare for and carry out the required fieldwork, induding Questionnaire completion, and sample collection. Ensure uniformity and consistency in the performance of the survey exercise. Ensure that quality and valid data are collected. Ensure correct administrative procedures are followed to make for a thorough and successful survey. Overview of interviewer nesponsibilities It is expected that the interviewer will: Become thoroughly through home study and attendance at training sessions familiar with the questionnaire. Assemble and organize survey materials before fieldwork. Be able to locate sample addresses and households. Enumerate members of the household and select sample persons. Administer questionnaires to the appropriate persons. Conduct preliminary quality checks on data collected and response status. Comply with administrative procedures for retuming completed questionnaires. Maintain regular contact with the supervisor. Undertake any other related duties assigned by the supervisor.

Preparation for the field What you will receive You will receive the following supplies: Writing materials and manuals (in a bag) Clip board Pencil Pen/biro Eraser Pencil sharpener Questionnaire booklet Interviewer's manual <1M) Food instruction booklet (FIB) Interviewers' logbook Household listing forms Anthropometric equipment UNICEF unit scales for measuring weight Height meter for measuring height or length 24-hr dietary recall Kitchen scales for weighing up to 5 kg Calibrated measuring spoon, cup, and glass Biological samples Sample collection kits for urine and blood sample (for use by medical laboratory technologist team for biological samples). A letter of introduction and an identity card. Check that the supplies listed above are complete and the equipment are functioning properly. If one is missing or it's not functioning properly, contact your su pervisor immediately.
6
Organize your assignment It is important that you plan your work to maximize efficient use of your time. Completion of each questionnaire should not exceed 40 minutes. Plan a travel route that would enable you to cover most households within a short distance. Each day before going to the field, check your supplies or items to avoid waste of valuable time. In particular, check your questionnaire for pt'inting defects or m issing pages. Check the scales and if necessary, recalibrate the scales. Keep all your materials secure. You will be responsible for accounting for all materials/items supplied, indud ing questionnaires, even those you have not used. Before going to the field, please go through the checklist of materials provided in Appendix 1 to make sure you take all what you will need for the field work.

Roles of interviewers Identify local guides dentify households in EAs assisted by the local guides Be satisfactorily identified by households (mode of introduction) Identify the respondents Establish adequate rapport with households and respondents (the dos and don'ts)
9
Contact with respondents How you present yourself at the door of the respondents usually determines how successful you will be with the interviews. Since it is your first opportunity to describe the survey to a respondent, familiarity with the introouction is important. This introduction is printed below:
Greeting for the time of the day (m local parlance). I am (your name) and we are members of a national food consumption and nutrition sUlVey team for the Federal Govemment of Nigeria that you have been told about. It has been noticed that young children and their mothers have deficiencies that may interfere with their health and welf-bein'J which need to be corrected Your household has been selected to participate in this sUlVey. This wilf involve you answering some questions, and we toking some measurements and samples. An experienced and quolified person wilf take these measurements and samples. The procedures are quic~ and vel}' safe, but some may be slightly uncomfortable such as taking blood and uone samples. Your answers wilf be combined with those from other households to make conclusions in which, I assure you, no person or family WIll be identified Our results are important in makIng decisions on how we can improve the health of our children. I am glad to answer any questions you may have.
Remember to communicate with the respondents in the language they speak or understand well and show your letter of introduction/identity card. You may need to satisfy the curiosity of most respondents and answer some questions about the survey. Listen patiently to the respondents' questions/concerns and provide only the information needed to remove any doubts and create a conducive atmosphere for the survey. Do not volunteer extra information that could be misunderstood or could confuse the respondent. If you do not know the answer to any question, admit that you do not know but offer to obtain an answer.
10
Questions likely to be asked by respondents Here are some possible questions from respondents, and suggested answers.
What is the survey about? The Federal Govemment and other organizations wor1<ing in Nigeria are interested in collecting information that will help them assist in improving the health and well-beng of Nigerians. Whom do you work for? I work for the survey team covering 72 local government areas and 216 enumeration areas. Our project coordinator is Dr B. Maziya-Dixon of the International Institute of Tropical Agriculture (JITAl, Ibadan. If you like, I can give you her contact address.
Why did you select me?Your household was selected randomly from a list of all households in your enumeration area in the LGA. How long will this take? The first part (household composition) should take about 15-20 minutes. If there is someone eligible in your household, the rest of the interview with him or her will take about 1 hr 30 minutes.
What are you going to ask me? I just have questions about the number of people in your household, where you live, what you eat, how you feel, who takes care of the baby, where do you go when you do not feel well. A member of my team will take measurements and collect some samples. What are you going to do with the information? The information will be used to compile summaries, which will assist government and other agencies in setting up policies and programs that will improve the health and welfare of the people. Your answers will be kept strictly confidential and your identity will not be revealed. What do I get from this? You and your household are likely to benefit from programs initiated by the government and other agencies that will address identified problems. In addition, you will also participate in the fomnulation of such programs.
On the average, the most productive times for contacting respondents at home are from 5.30 to 7.30 am in the morning and from 4.00 to 7.00 pm in the evenings. Of course, this will vary with area and occupation of the respondents. Late afternoons and evenings are the most productive times in most cases. Wherever possible, make contact with a neighbor to find out when the respondent is likely to be home.
11
Household eligibility criteria To qualify for enumeration, a household should have a: mother child of this mother aged less than five years. Where the mother has more than one child aged less than 5 years old, the youngest child should be selected for sampling. In a household where there is more than one eligible mother and child pair, the youngest mother and her child should be selected. Refusal In a study of this nature, if the public is adequately mobilized to understand its importance to the nation and the long-term benefits to the people as the recipients, a well trained interviewer who is professional and confident will largely receive warm and positive responses from all households. However, you may find some few respondents who may not cooperate. In such a case, you will need to use your initiative to decide the next step to take. If the person refuses to take part but does not object to your conducting the interview with someone else, you should continue the interview with another knowledgeable household member. But if the person refuses to take part in the exercise and objects to your conducting the interview with someone else, accept the refusal. apologize for taking their time, document the refusal information, and leave the door open for another interviewer to contact the household. Difficulties in locating the household Although the listing will be conducted with great care, there is always the possibility that you will encounter a problem locating or identifying sampled households. To avoid difficulty in locating the households, enumerators are encouraged to work closely with local guides and enumeration area leaders. If, even with the help of the local guide and leader, the sampled household cannot be located, review the listing sheets and maps carefully before leaving the area. If your best efforts fail, sketch a map of the immediate area and contact your field supervisor. If you are positive that you are in the right area and the household does not exist, document this finding and provide explanation of what you think might have happened, if possible. Difficulty in finding people at home This can largely be avoided if a prior arrangement is made with the enumeration area leader or opinion leader who will help to sensitize the people for the interview. People in this category could be reached early in the moming before they go out for their businesses or towards evening when they might have returned. In a rare case, where the household to be sampled has moved away, it should be indicated so. We expect that in most cases you will be able to complete the questionnaire with a household member in one visit.
12
When this is not possible with one visit, you are required to make two more visits in order to complete the questionnaire. II the members of the household at the sampled address are not there the first time you try to establish contact, you should try again at a different time and day. On the second unsuccessful attempt, you should contact a neighbor in an attempt to obtain information about the best time to contact the household. If the third (final) attempt with the respondent is also unsuccesslut report the case to your supervisor. Another household may be sampled from the list 01 households in the enumeration area.
13
Survey sampling frame and design Introduction The design targets the whole Of Nigeria. Considering obvious and documented relationships among: the agroecological zone and type of farming systems, crops grown and food consumed, type Of food consumed (intake) and micronutrient deficiencies. Nigeria was initially stratified according to major agroecological zones and predominant food crops within agroecological zones. Owing to lack of information on the principal variables Of interest in the study, a sample size consistent with the cost Of survey and availability of resources was aimed at. It is postulated that a large sample size, spread across agroecological and food type zones shall be fairly representative Of the whole country. Sampling procedure A stratified multistage procedure, with stratification at two levels, i.e., agroecological zone <AEZl and principal food crops (PFO were used. Figure 1 shows the different AEZ while Figure 2 shows the crops grown within each AEZ. AEZ 1 is essentially a dry savanna zone, while AEZ2 and AEZ3 are predominantly moist savanna, and humid forest zones respectively. The PFCs range from mainly cereal food crops to root crops and their combinations. Three PFCs were identified in each of AEZ 1 and AEZ2, while 4 PFCs were identified in AEZ3 ITable 1>. Table 1. Agroecological zones (AEZs) showing states in each zone and number of principal food crops (PFCs) per zone.

Selection of states In each PFC, a random sample of one of the states within the particular PFC was taken (with the exception of a PFC in zone 3 where 2 states, due to the larger number of states present were taken). Selection probabilities of states ranged from 1/18 to 1/48 (i.e., proportional to sizes of sub groups). Twelve states were selected.
Locol Govemment Areas (LGAJ Presently there are about 774 LGAs in Nigeria. Within each selected state, a listing of LGA was obtained, grouped according to the level of urbanization (urban, medium and rural) by Nigeria's Federal Office of Statistics. One consideration formed the basis for the selection of the LGAs. This was the need to ensure that the LGAs represent a range of rural/medium/urban conditions. For ease of coordination, the states selected were placed in their respective zones as follows: Zone 1: Barno, Taraba, and Nasarawa
Zone 3: Kwara, Osun, and Edo
Zone 2: Kebbi, Kaduna, and Kana
Zone 4: Bayelsa, lmo, and Akwalbom
From each selected state, sampling was done such that all the 3 LGAcategories (rural, medium, and urban) were represented. Further stratified sampling with probabilities proportional to number of LGAs in each category was adopted, subject to additional conditions that a minimum of one LGA from each group within LGA and a maximum of 18 for all the states making up a particular zone were selected. The practical method for achieving this involved random selection of one from each of the 36 categories <12 states times 3 LGA groups), and the allocation of the remaining 36 samples proportionately to the total population of LGA groups. Sample sizes, for this stage of sampling, are given in Table 2, while a listing of the selected LGAs are given in Table 3. Table 2. Distribution of sample by LGA categories and states. Zone

Enumeration Area (EAJ The EA is the smallest geographical cluster of household as delineated by the National Population Commission for purposes of enumeration. The number of households within the area determines the size of the enumeration area. The population of each of the enumeration areas will be obtained from Ihe LGA headquarters.
17
To facilitate the actual location of ruraVmedium/urban LGA from selected LGAs; the enumeration areas (EAs) that fall entirely within a selected LGA will be sampled . A comprehensive list of all the enumeration areas (EAs) in selected LGAs will be obtained from the National Population Commission (NPO. Three EAs will be randomly selected from among the list of EAs that are within a selected LGA. It is from these selected EAs, that a further breakdown of EAs will be made for the selection of households.
Household listin9 The household (HHl unit represents the smallest unit to be observed. A household is defined as a family unit that feed from the same pots and has a recognized head of authority. You will receive a detailed EA map and a household listing form to record information on the entire households in the EA. The EA map will indicate where to start the listing and numbering and where to stop. A list of all the households in each enumeration area will be made and every housing unit should be given a "FCNS", serially. Th is should be boldly written on a conspicuous part of the house. Detailed information (addresses) of the households is to be properly documented so they can be identified or located. Households with below five-year old children, women of childbearing age and/or pregnant women will be identified during household listing, and shall constitute the target population .
Selection of e/i91ble households A modified form of stratified quota sampling, with random components, will be used to select eligible HHs from the target population generated in 6.2.4. A random order of eligible HHs in each EA will be obtained using either a table of random numbers or the 'hat method'. You will then visit HHs in the random order generated. Where there is non-response (e.g. unwillingness to be interviewed, absence of HH head, empty HH, etc.) you will ignore the HH and move to the next on the list until the sample of size 30 eligible HH in the EA has been obtained or the population of eligible HH exhausted. In this way, non路response may be minimised, though you should expect to move back-and forth in the EA. The latter is minimised by splitting the eligible HH into 2 on spatial-basis for 2 teams (e.g. stream running across EAl and the sample of size 30 split proportionately to the size of the strata. Altematively the number of HH may be split exactly into 2 and each team allowed to quota sample a maximum of 1 5 HH. The modified quota method is illustrated below.

Let's assume it is the 6th column. Run through the column circling the number corresponding to eligible HH numbers. When you reach the end of column 6, continue on column 7 from the top and maintain this consistency. Continue with the process until the sample size is achieved or end of target. !If you continue from the bottom, move up to the top and then continue from the top of 8 to its bottom etc} In the example, the numbers that appear in the table are in the following order: The only unit in column 6 is 20 and then from the top of column 7 etc.32, 22, 10, 21 11,02,30,13,08,12,04,09,29 [In practice, you will identify the first and then move on to the next without necessary having to print them out. Your guide is the table.l (iii). This is the order <IJ for hat method and (ii) for the random table method for one team with an intended sample size of 5.
D. Selecting the 5 The interviewer goes to FCNS 32. If available or HH head is willing, information is obtained and then move on to 29. The process continues until the sample of size 5 has been obtained or the end of the population reached. In the example, the numbers that appear in the table are in the following order: The only units in column 6 are 12, 02, and then from the top of column 7 etc. 06, 01, and from column 8 we get the 5 one, 03. (Note that once a number is selected, it is not selected again even if il appears several times in the randam table).

In practice, you will identify the first and then move on to the next without necessarily having to print them out. Your guide is the table. This is the order for the random table method for one team with an intended sample size of 5. If none or some of the 5-selected EHH are unavailable, selection continues from the last number (i.e., 03) until the maximum of 5 or end of EHH listing is reached. Administering the questionnaire The interviewer goes first to FCNS 07, HH 02 where EHH 12 is based. If available or HH head is willing, information is obtained, and the interviewer then moves on to EHH 02 (located in FCNS 0 I , HH 04). The process continues until the sample of size 5 has been obtained or the end of the population has been reached. You will receive a detailed EA map that will enable you to do the household listing of the entire households in the EA. The EA map will enable you to locate the household, and information on household (HH) listing form will assist you to locate the HH. Once in the EA, you should carefully go through the household listing form to obtain the address and other description of the HH to enable you to locate it. From this collection of addresses and locations, a sample will be drawn. In order to locate the sampled household, you will need to understand the definition of household in the context of the survey.
22
Who qualifies as a household member>
The following individuals shou ld be counted as household members: Persons who usually live in the sampled household and who are living at home at the time of the contad; or temporarily absent at the time of your contact (e.g., on vacation, short-term hospitalization). Domestics and other employees who usually live and sleep with the household. Who does not qualify os a household member>
The following persons do not qualify as household members: Persons temporarily visiting the household who have a usual place of residence elsewhere to which they are free to retum at any time. Persons who take their meals with the household but usually lodge or sleep elsewhere; domestic employees or other persons employed in the household who live in a separate house.

Selection of persons for 24-hour dietary recall ond anthroporr>emc study From each eligible HH selected in selection of eligible households, mothers with paired children below the age of five, and pregnant women will be identified. One of such paired mothers and children below the age of five will be selected using the criterion of youngest child from each HH.
Selection of persons for biochemical measures Blood samples for biochemical analysis will be obtained from persons selected as for selection of persons for 24-hour dietary recall and anthropometric study.
Pregnant women Five pregnant women will be randomly selected from the antenatal clinic (serving the EAl and eligible HHs in each EA. Pilot study For a study of this magnitude and importance, it is essential to test all aspects of the materials and procedures to be used before the main study begins. The pilot study will test the use of the questionnaires and procedures designed for use in the main study, and logistics. As part of the planning process, a pilot study duplicating the planned survey design on a small-scale was conducted from March to April 2001 . The project coordinating team members will review the planning of the pilot study. The pilot study will be conducted in each zone. One LGA and one EA will be selected in each zone. Ten households will be interviewed in each selected EA. making a total of 40 households. All parameters will be taken during the pilot study. To capture experiences and provide a feedback on procedures and materials, interviewers will maintain a logbook as part of their review of completed questionnaires and submit a debriefing questionnaire. Field observations by state supervisors will provide additional information for identifying areas for improvement.
24
Administering the questionnaire The questionnaire for the food consumption and nutrition survey has six sections: Questionnaire identification Household/demographic information Food security Assessment of nutritional status (24-hour dietary recall) Health and care Anthropometric and biochemical measurements Each section has segments, all of which must be completed by the interviewer, not the respondents. The questionnaire identification section is of critical importance, requiring 10 pieces of information, 8 of which are to be completed before the interview begins. Locating the sample households To locate the sample households, the interviewers are strongly advised to introduce themselves to the community leaders of the EA, and possibly employ the services of a local guide. In addition to the guide, the selected households will be located using the sample household listing form completed earlier and a map for each EA that will be provided by the supervisor. Administering the questionnaire For clarity, the components of this section are addressed in sections corresponding to the section number as it is in the questionnaire. However, the box in the top right hand corner (address, state, LGA, and EAl should be completed and written in words before proceeding to Section 1.

The full FeNS number should be entered in the questionnaire identification mainframe. Write the prefIX and the code number in the questionnaire identification mainframe. Housing units have been preselected by a modified form of stratified quota sampling with random components. Household number within housing unit: The sample household within the housing unit should be identified with a two digit serial number (01 , 02, 03, etc.) to be determined during the household listing exercise. The letters "HH" should prefix this household number. Only eligible households are sampled (see household eligibility criteria, page 12). Household head: The first and surnames (family name) of the head of the household should be entered in the questionnaire identifKation mainframe (during the interview). Address: The location where the interview is conducted (e.g., number of house, street name. area name, and questionnaire number) should be written in words at the top right hand corner of the page.
26
Number of persons in household: The total number of persons who regularly
live in the household should be entered on the questionnaire identification mainframe after completing the household composition table. Response slatus: This section of the questionnaire must be filled just before leaving the household . The team leader or member who was recording during the interview should fill the name and date. The time when the interview began should be recorded on the top left side of page 1 of the questionnaire below the box for recording zone code.

Socioeconomic characteristics This section shou ld be administered to the head of household. Row 1: Primary occupation of head of the household - Only one code (of the primary occupation) should be entered, to ind icate respondent's major source of income. Row 2: Primary energy source - This refers to electricity source, if any, and only one primary source should be indicated. Row 3: Primary source of water - Where the source of drinking water is different from the source of water for other domestic uses, the primary source of water for domestic use should also be indicated (but in parenthesis). Row 4: Primary method of refuse disposal - The interviewer should observe to see if respondent's answer contradicts facts on ground, and reconcile by gentle probing. Row 5: Main type of toilet - The interviewer should differentiate between a simple pit latrine (the more common), and a ventilated improved latrine. Row 6: Estimated annual income - Wherever possible, all incomes in the household in one month should be added up to obtain an estimated average income which is multiplied by 12 to give approximate annual income of household. It may be best to ask this question last in this section by gentle probing .

Food security (page 4 of the questionnaire) This section is made of 3 separate but related parts, food items consumed at home, food consumed away from home and food-related coping strategies. The interviewer will ask relevant questions and fill in the answers given. The time for all 3 parts should not exceed 40 minutes. Food security refers to availability and adequacy of various foods within the household while Food Availability in this context means the duration in which the household can obtain food items. Food Affondability refers to duration in which the household has econom ic access to the food items. Household food security: food items consumed at home The purpose of this section is to track the availability, affordability, quantity, and costs of food items consumed in the household. Preferably, the woman should answer the questions in this section. In cases where somebody else buys the food, then that person should respond to questions in this section . Note the quantity of food referred to here before the whole household; it is better estimated as raw portion. All the foods are already put into food groups, below which we have food items. Interviewer should complete the column(s) on food availability/affordability first.
Column A: foods Always begin from cereal, and take every group one after the other. Do not skip or jump; go from cereals through roots and tubers to fats and oils. Where interviewers are not sure where other foods mentioned belong, please consult the Food Instruction Booklet.
Column B: Food availability Ask this question: "For how many months in a year is (name of food item) available in the market for purchase or in the farm?" You can give the options to the respondents to pick one. In each group, probe for other food items in the group that are common, is it eaten in the area, and ask how much of the year they are available for consumption .
Column C: Food aHordabiliCy "For how many months in a year is (price of food item) affordable to the household: Record the number of month against the particular food item.
Columns D and ÂŁ: Frequency of consumption Interviewer should complete the column(s) on frequency of consumption last. Ask: "How often do you consume/eat (name of food) in a week? If consumption is more
34
than once daily, tick; if otherwise, write the number of times in Arabic numerals (1, 2, 3, etc.) in the appropriate column in front of the food item. ColumnF
Describe the food e.g., yam, gari, pounded yam, rice (what was the size before cooking?). Emphasis should be on units. Columns G and H
It is also good to know the proportion of food from market and that from own production, e.g. 2 out of 10 or 4 out of 10, etc. The total of Column G and H should be 10. Note to the interviewer. Apply the participatory rural appraisal (PRAl technique to allow the respondent to easily answer the question about the proportion of food for Columns G and H as follows: Step 1: Collect 10 stones (or any other object such as palm nuts) of the same size and show them to the respondent. Step 2: Ask the following question: "Assume that the total quantity of food (give the name of the food in column a) eaten in the last one week is equal to these 10 stones, please take out of these 10 stones those stones you think correspond to the proportion of food from own production." Step 3: Write the number in the cell under column. Step 4: Ask the respondent to confirm that the remaining stones will correspond to the food from the market. This probing question could allow the respondent to eventually revisit the answer given at step 2 above if the respondent over- or underestimated proportion of food from own production. Step 5: Write the number for proportion from the market in the cell under Column h. Step 6: Remember that the total of Columns G and H should be 10. Columns I and J:
The cost of these food items is very important. whether or not they are obtained from own farm or purchased. This will help estimate quantity etc. The cost of processing should also be included, e.g., the cost of milling maize grain to make okamu.

Food security: Food items consumed away from home (pages 11 of the questionnaire) The purpose of this section is to capture the food items and the expenditure on such food items consumed by household members away from home on particular days within the last one-week. Column 0: Always begin with the names of household members who ate away from home in the last seven days. Do not skip or jump; Go from one member to another on the list of members indicated. Where respondent is not sure, please allow him to consult the household member concerned. Indicate the serial number of each household member who ate away from home within the last week starting from the first household member concerned.
For these members ask which day(s) they ate away from home and record the response on the appropriate day(s). For example, if the household member ate outside the home only one day of the week, tick Day 1. If they ate for two days, put the responses in Day 1 and Day 2, tick day 1 and Day 2. If they ate for seven days, then tick all seven days from Day 1 to Day 7. Complete the questions for the first household member who ate away from home before you go to the next household member who also ate away from home. Column b: For each day ticked, and for each household member, indicate the name(s) of food eaten on that day in column b. For example, if the household member ate rice and beans in Day 1, indicate nce/beans in Column b against the name of the household member. Column c: Ask if the food item was purchased or not purchased. If purchased (write Y> and if food item was not purchased (write N), Column d: For this food item, ask for the amount paid (Naira) for the purchased food or estimated market value for un purchased food, Complete this for each food item consumed away from home for each member for that day, After the list has been exhausted for that day, ask same questions on other days of the week.

Food-related coping strategies (page 13 of the questionnaire) Tact is needed when asking the lead ing question in this section. Read out every strategy presented in Column b 0-1 2) and wait for response after each strategy. Identify those strategies that are employed and tid< under Column
c.
Do not omit any of the 1 2 options listed and see bottom of this page for a definition of ' street foods'. In eliciting infonmation on who gets the least share of food in the household, you should exercise care not to be suggestive. The strateg ies indude: Rely on less preferred food Rely on less expensive foods Borrow food stuff/money to buy food Purchase food on credit Rely on relatives or friends Limit portion of food at meal times Ration money to HH members to buy street foods Limit your own intake to ensure ch ildren get enough Reduce the number of meals in a day Skip whole day(s) without eating Others <Specify) What are your coping strategies? What are the ways and means by which the HH obtains food when there is not enough money or food available to eat? Begin with a general question, e.g., would you say that in this HH there is always enough food or money to buy food for all' Then check through to see where the response falls. Where the response is not any of those listed, write under ' others'. Street foods: Ready to eat food that is purchased from street vendors.

Assessment of nutritional status: 24-hour dietary recall (page 14 of the questionnaire) This section is divided into 2 parts, 24-hour dietary recall for mother and children under the age of 5. The 24-hour dietary recall is a complete record of every food item eaten by the respondent the previous day before the interview day. This segment should be administered to the mother/child pair. Be familiar with the instruction booklet (FIB). Note the place where food was eaten, and the time. Assign an item number to each food and obtain a detailed description of the meal/snack ingredients, method of preparation, and additions such as sweeteners, etc. Obtain an estimate of the amount of each food item consumed. Remember to administer this questionnaire to each of the 5 selected pregnant women per EA. How to conduct the 24-hour recall for the mother (Respondent: mother
with an underage five-chi/d) General prlndples The 24-hour dietary recall is one of the quantitative methods of assessing an individual's dietary intake. The objective is to obtain information on the respondent's exact food and fluid intake during the previous 24 hours. Since questions of a personal nature are going to be asked, it is important that the interviewer displays a friendly and diplomatic disposition. A pleasant and conducive environment is also important, preferably, away from distractions and hunnan traffic. It is important that the respondent be allowed to sit down or continue with minor chores during the interview if it is impossible for her to remain idle during the interview period.
Preliminaries It is important that both interviewer and respondents arrive at a mutual convenient time. However, in doing so, it is important that as much as possible, the respondent should not be given an advance warning that a 24-hour dietary recall will be conducted. It is also important that the interviewer: Introduces his/herself Shows identity card and introduction letter Establishes a rapport with the respondent Explains the objectives and rationale of the exercise to the respondent (and perhaps also the spouse)
47
Emphasizes the importance of accurate recollection Assures the respondent of the confidentiality of their responses. Some do 5 and don'ts It is important that at all times during the interview, the interviewer must: Endeavor to gain the confidence of the respondent's e.g., using warm greetings (preferably in the local language), presenting a diplomatic and professional demeanor. Focus on and empathize with the respondent. Always listen attentively to the respondent. Focus on the details required i.e., the description of the food and the exact amount eaten. Show interest and convey understanding at all times. Maintain a nonjudgmental attitude to all answers provided by the respondent. It is also important that the interviewer avoids doing anything that could upset the respondent or compromise the quality of information obtained during the interview. In this respect, interviewer should NOT: Talk down to (like a senior talking to a subordinate) any respondent at any time during the exerdse Comment negatively about the living environment of the respondent or the community Offer finandal or other inducement in exchange for information Cross-examine the respondent Make quick assumptions and conclusions (i.e., always clarify from respondent about what you think they mean) Provide information for the respondent Make judgmental statement or show judgmental attitude to any answers The IntelVlew Having gone through the preliminaries and introduction and also ensured that everything required for the interview is ready, the interview can then begin. In general, the 24-hour recall technique is conducted in four stages, using a standardized protocol. Stage one: Recall of foods and drinks consumed (Column a and b) In this stage, the respondent will I>e requested to recall, as much as possible, all the foods and drinks consumed in the previous 24-hour in a sequential manner. It is therefore customary to start in the morning. A typical question to start with:
48
"I would like you to tell me what you had to eat and/or drink after you woke up yesterday morning?"
Column a. Record the first item recalled as item number 1 in this column. The numbering should be done serially. It is recommended that the interviewer complete each row for each food/drink and addition before listing the next item. Column b. The name of the food/drink and addition mentioned should immediately be written in this column. This should correspond to the item number recorded in Column a. Once that has been recorded, you can then proceed to ask the next question: 'What did you have next? Enter the response in Column a as item number 2 and the name of the food/drink should be entered in Column b. This last question can then be repeated as necessary, until the time given reaches 24 hours. Questions about specific meals (e,g" breakfast, lunch, snacks or dinner) should be avoided, (See FIB for details of prompts).
Stage two: Description of foods and drinks consumed (see FIB) (Column d Each time the interviewer collects infomnation on the list of what was consumed by the respondent further probes on the full description of the foods and drinks should be undertaken using the relevant food group sections in FIB. Cooking methods or recipes and brand names, if possible, should be requested. Guides for the appropriate prompts for specific foods are in FIB.
Column c: Detailed information on cooking methods or recipes and brand names, if possible, should be requested and entered in this column .
Column d. Did you eat that food at home? Record name of place where the food/ drink was taken e,g., restaurant, street food, etc. Column e. What was the time or and when was that? Record the time when the' food was taken, e.g., am, pm. Stage three: Estimation of amounts (Column
f)
This is a critical stage of the recall process. Using different prompts, the interviewer should elicit infomnation on the amount of each item of food consumed and record in Column f. If liquid, volume should be used. The interviewer should show several cups or glasses of different sizes and known volume to the respondent and inquire if any of the sizes represents the amount consumed . The equivalent weight of the amount corresponding to that size cup or glass should be recorded in the last column (Column g) of the dietary recall form.
49
Column f.' Record amount of each food item eaten For weight. food models and portion size of predetermined weights for homeprepared meals should be used. The interviewer should show them as appropriate to the respondent. If a Iruit for example, different sizes 01 oranges, pawpaw, mango, or banana should be shown to the respondent who will pick the appropriate size to be recorded by the interviewer. For meals, portion size could be determined either by asking for the price of the food combination, if purchased from a vendor, or by showing portion sizes for the respondent to pick one or using different bowl sizes to estimate weights. For estimating these weights, a table has been provided in Appendix 7.
Stage four: Review of data (Column g) At the end of the interview, a recap should be given to the respondent to reconfirm choices made, and have been correctly recorded . This can be achieved using a statement such as 路1 will read back to you what I have recorded to make sure that I have not made any mistakes: A question to elicit information from the respondent on the use of vitamin and mineral supplements, if it was a feast day, if they were ill and the consumption of fermented beverages (e.g., Nono, Burukutu, Pito, etc.) should follow this. If the answer is "Yes路, record each item on a separate line in the category column, and complete using Column C, and C, of FIB. As a final check, the interviewer should scan the recall in case any food groups have been omitted. Since this is a once and for all interview, it is necessary for the interviewer to inquire whether the day recalled was a normal (usual) day. If the answer is in the affirmative, then the interviewer should thank the respondent politely for his or her cooperation . If the answer is in the negative, the interviewer should ask for what a day would be (repeat the process).
Column g. Interviewers are not to enter the weight equivalent of foods. This will be done centrally by the zonal coordinator.

How to conduct the 24-hour recall lor the under-5 child (page 16 01 the questionnaire). Respondent: mother of the under 5 child or suitable proxy The proxy interview for an infant or child under 5 years may be the parent, grandparent. or any other person knowledgeable about the child's feeding/intake. If the infant or child has more than one caring for himlher, both may need to help complete the interview. If the sample child is under 1 year old, you may use this introdudion: As with the standard introdudion, explain the information you need and define the time frame for the proxy. Since infants frequently have feedings at night, it is important that the proxy understands the time frame. You may start by saying, 'Today is (OAYl. I would like you to tell me everything the baby had to eat and drink all day yesterday, starting at midnight. Indude everything the baby had at home and away from home, including snacks, bottles, and breast milk: Use the Food Instrudion Booklet for corred probes and quantity documentation. Interviewing children: All children must be interviewed with a proxy. The preferred choice to help the respondent is the person primarily responsible for preparing the meals for the child. One of the interviewer's tasks is to assess who is the best respondent or combination of respondents for the child. We assume that a child younger than 5 years cannot reliably report for themselves. Although they may contribute useful information, data on their intake will normally be obtained from one or more proxy respondents.

Health and Care (page 17 of the questionnaire) Child health This section of the questionnaire deals with the assessment of the state of health of the child and should be administered to the mother of the under-5 child. It covers the preventive measures that are being taken to ensure that the child stays healthy and the treatment that is given to the child when he or she falls sick. The section has 6 component parts - numbered 1-6. Wants to know if the child had been sick during the last two weeks. It requires a Yes or No answer. Wants to know how often the child has had the listed sicknesses this year. You should indicate the number of times against the illness, where applicable. Where other sicknesses outside these common ones are mentioned, they should be specified. Note that regardless of whether the child had been sick or not in the last twoweeks (i.e., answer to question 1 is No) this question (number 2) should be answered. Remember to use the local names of the sicknesses when dealing with an illiterate mother. In this segment which deals with where the child received treatment, you should tick ( ) the appropriate response. Note that some illiterate mothers in the rural setting could refer to a chemist (the owner of a medicine shop) as a doctor, which may give the impression that the child received attention in a hospital by a qualified medical practitioner. Where you suspect this, please probe further to get the true picture. Tick as appropriate Tick the appropriate box For this question, physical examination of the health card of the child is required.

Care for women (respondent: mother of the under-5 child) (page 18 of the questionnaire) This segment should be administered to the sampled mother in the household. Interviewer should exercise extra sensitivity in eliciting information for this segment and, as much as possible encourage information to be volunteered, not extracted from the respondent. Workload: is defined as sum total activity other than rest and sleep. Empowerment: includes the degree of confidence which the woman enjoys to express her views and make decisions affecting herself as well as the household. The interviewer should make an effort not to influence the response in anyway, for example, showing of concern or a questioning. Reproductive rights: include the degree of freedom the woman enjoys to choose whether or when to have a baby, as well as the support she receives during pregnancy, the prenatal. and postnatal periods. â&#x20AC;˘
The interviewer should differentiate between improved food share arising from recognition and support of the pregnancy by the household and increased food intake necessitated by increased appetite during pregnancy. Economic rights: include the degree of freedom the woman enjoys to choose what she engages herself in within or outside the vicinity of her residence to generate income, as well as what she does with such income. The interviewer should differentiate traditions, which are imposed by the head or other members of the household from traditions, which are cultural practices of ethnic, religion, or other groups.

Focus group discussion guide Focus group discussion (FGDl guide The focus group discussion guide is a set of short questions to be used for guiding a discussion with a selected community group. The purpose of FGD will be to appraise community opinion on issues not covered by the household questionnaire, such as HIV issues, food processing, complementary feed, etc. In other words, FGD is expected to complement the household questionnaire. One FGD will be conducted per enumeration area making a total of 216 FGDs. For this exercise, it will be useful to have a battery operated audiocassette recorder to record proceedings. However, it is important to ask participants for permission to record the proceedings. The following questions are simply guides to the themes of discussion. In the report for FGD, clearly identify the "group focus", the size, any prevailing situation, location, and time. Themes
Breastfeeding: awareness of minimal feeding practise to cover items 1, 2, 5 of the guide. Infant feeding and complementary foods (CFl: Complementary foods are foods that are given to infants when breast milk only is not enough. There are usually given from age 4 months. Awareness and practices of growth monitoring, how do we recognize that a child is growing well, i.e., the child is having enough food, appropriate for growth? Family planning and child-spacing (planned parenthood): How can a woman be able to breastfeed as long as she desires without the fear of another pregnancy? What do you do? Uses of maize and preferences if any, for certain varieties, etc., e.g., white versus yellow varieties. Most complementary foods are maize-based. Awareness, preventive measures, and community attitude to HIV/AIDS infection. Awareness on foods that give you good sight etc. (micronutrient deficiencies). Is there any other thing that you would like to tell us, ask, or suggest? Thank you.

These steps include: Field editing Validation of field data by state supervisors Field observations by focal persons and a central monitoring team Feedback from monitoring team/focal persons Fine tuning procedures and specifications The interviewer should carry out a preliminary check on the completed questionnaire before signing the data collection column on the response status. He should also check other documents including the labels on the samples collected in the field before forwarding them to the state supervisor. This field check must be done as soon as possible after completing the interview and this in any case must happen ~ the next day's interview. The focal person will carry out the office editing and sign the appropriate column before dispatching the questionnaire and samples to the national project secretariat. The purpose of the editing is to: Pick out and correct or explain errors and omissions in recording. Common errors include ticking wrong boxes or columns and inserting wrong codes. â&#x20AC;˘
Reconcile inconsistencies in the entries, which definitely resulted from a mistake by the interviewer. This is possible because the information is still fresh in the interviewer's memory. Enumerator errors should be noted in the enumerators' logbook and reported to the supervisor. Learn from mistakes made so that they are not repeated. Ensure legibility of the written responses.
74
Validation of field
data
The state supervisor is to carry out field validation to ensure that the selected LGAs are those that have Deen done and that correct procedure were followed during the interview. Field observations During the survey, the state supervisor, zonal coordinator, and the central monitoring team will conduct in-person observations to ensure uniformity in what is being done and that correct procedures are used. Field findings/difficulties can De used to further evaluate procedures and designs. Feedback from monitoring teamlfocal persons Following the assessment of completed questionnaires and field observations, problems noticed should De immediately communicated to the state supervisor with suggested solutions. Upon review by supervisor, zonal coordinator and principal investigator, corrections will be communicated to the interviewers. Fine-tuning procedures and specifications It is not possible in a national survey of this nature to anticipate every situation that may arise during data collection. A pilot study will De conducted to fine tune survey operations as much as possible. However, if it Decomes necessary, provision will be made to modify or add to the procedures and questionnaire specifications during the national survey.

Appendix 5.
Protocol for taking anthropometry (adapted from Gibson 1993)
Weight measurement For infants and children, a pediatric scale should be used where possible, with a scale pan large enough to support the weight of the child. In the field, a suspended spring balance and a weighing sling may be used. After slipping the subject into the sling, record the weight as soon as the indicator on the scale has stabilized.
For older children and adults, use a bathroam scale The scale should be calibrated regularly and whenever it is moved to another location. Place the scale on a hard flat surface. Calibrate the scale with known weights and zero it after every subject. Ask the subject to stand unassisted, in the center and to look straight ahead, standing relaxed but still. Record any signs of visible edema, if present. Record the body weight to the nearest 0.1 kg.
Height measurement Clothing should be minimal when measuring height so that posture can be clearly seen. Shoes and socks should not be worn. Ask the subject to stand straight feet together, knees straight, and heels and buttocks and shoulder blades in contact with the vertical surface e.g., wall. Make sure the arms are hanging loosely at the sides with palms facing the thighs; the head is not necessarily in contact with the vertical surface. For younger subjects, it may be necessary to hold the heels to ensure they do not leave the ground. Record the height to the nearest 0.1 cm. Take note of the following precautions that need to be taken when taking measurements:
Wei9ht measurements Check proper functioning of the scale. Remove all additional weight sources (shoes, pocket materials, etc.). Ensure calmness during weighing. The reader of the scale should be properly positioned besides the subject to accurately read the scale to the nearest 0.1 kg,
111
Heights measurements Surface being used must be upright and subjed must stand on a flat surface. No shoes and caps. Headboard should be adjusted to the level of the scalp. Reading is to be taken to the nearest 0.1 em. In cases where large amounts of adipose tissue prevent the heels, buttocks, and shoulders from simultaneously touching the wall, subject should simply be asked to stand ered. How to measure the length/height of an infant Place the infant on a length mat or any flat surface with a measuring device marked in centimeters. Place the infant facing upwards (on his/her back> ensuring that the heels are level with the zero mark of the measuring device, with the toes pointing straight upwards. Press down the knees of the infant to touch the flat surface with the hand by the sides. Adjust the neck and head so that the child is looking up and absolutely flat. Take the length by placing a headboard or ruler against the SGllp. How to take the weight of an infant Weigh the mother and the infant together and then the mother alone, using a weighing scale. Subtract the weight of the mother alone from the weight of the mother and the infant to get the infants' weight.

Appendix 6.
Protocol for collecting biological (blood and urine) samples
Blood samples for ferritin, zinc, and vitamin A Once blood is removed from the body, vitamin A as well as carotenoids is susceptible to losses that can be minimized by rapid separation of serum from red blood cells, protection from light, handling in an air, (oxygen) free atmosphere, such as under nitrogen; and immediate analysis of freezing. Since field conditions do not always allow ideal conditions to be met, alternative procedures have been devised, which minimize extrinsic error in estimating true vitamin A levels. The preferred and alternative procedures, as well as improper techniques are summarized in Table 1. Samples should be protected from exposure to air, and from light and warming from the time of collection to the completion of the analysis. In the case of unavoidable delay in centrifuging blood, place the blood samples in an insulated cooler with wet ice, seal with quality stoppers, transport to the laboratory, and separate the serum soon after arrival. Special care must be taken to prevent hemolysis during transportation, particularly when traveling on rough roads where shaking becomes critical. Suspending the cooler with samples in the vehicle may minimize this risk. Serum specimens must be stored under an inert gas at -8째C (freezer compartment of a regular refrigerator) for up to five days. Then, the samples, while maintained in a frozen state, should be transported to liTA. Table 1. Collection and handling of blood samples.

Collection and handling of blood samples: The specimen of choice for the analysis is venous blood. Venipuncture is the method of obtaining it. The subject should be comfortably seated or supine, if sitting is not easible, and should have been in this position for 10-20 minutes before the specimen is drawn. The median cubital vein in the antecubital fossa or crook of the elbow and the dorsal side of the hand are the preferred sites for collecting venous blood in both children and adults. The skin over the area of intended vein puncture is cleaned with cotton wool saturated with 70% ethanol solution. The skin is allowed to dry in air. A tourniquet is applied 4-6 inches (10-15 crn) above the intended puncture site to obstruct venous return and hence distend the veins. A tourniquet should not be left in pOSition for more than two minutes. A sterile, sharp 23G butterfly needle (Abbot), with a 5ml syringe (Promexl attached is used to obtain venous blood from children and adults. 3ml of venous blood are withdrawn from each subject. When blood collection is complete, the tourniquet should be released and then the needle is withdrawn. Dry gauze is held firmly over the puncture site for 10-15 minutes. This is transferred into a vacutainer with clot extractor (4-6 ml tubes) and left to stand for about two hours. Separate the serum from the blood cells by centrifugation at 2500 rpm for 10 minutes. Meanwhile, keep it cold and covered. Decant the senum into Eppendorl save lock tubes (size 1.5 mil and label for the individual. The serum should be enough to analyze for: - O.3ml/300 microlitres for serum retinol - 0.5ml/500 microlitres for serum zinc - 0.2ml/200 microlitres for serum ferritin Storage of samples: Samples are stored at minus 20째C before dispatch. Transport should be on dry ice to last the entire journey to the laboratory for analysis. Samples for vitamin A must be protected from light by wrapping samples in aluminium loil and storing in a dark cooler box. Labelling: Before collecting the sample, the phlebotonist verifies the identity of the subject by requesting the subject to hand over the slip given to the subject by the interview team. The label should contain the following: LGA code, EA code, questionnaire number, and subject (mother, child, or pregnant woman). 117

Transport of samples: Use resealable plastic bags for keeping batches of samples. Seal all samples tubes and keep out of direct sunlight. Keep cool and transport on dry ice and send by courier service. Collection and handling of urine samples Adequate quantity of casual urine is collected using a clean cup. This is transferred to sample bottles. 5ml of urine are placed in nongraded 5-1 Oml transport tubes with tight screw caps. Each sample is well labeled with Name, Age Sex, and Questionnaire Identification number. Note: Use xylene-free permanent marker for marking bottle, tubes, and labels. Samples should be kept at - 20째c. Use resealable plastic bags for keeping batches. The urine sample is for analysis of urinary iodine. Note: all samples to be handled with an operator wearing gloves.
