Preface to first edition The doctor who tells a mother that her newborn infant resembles the father is either simply making conversation or is not very knowledgeable about the basic principles of human growth. The newborn is always a poor replica of the parent, with its large head and trunk and its disproportionately short arms and legs. A newborn is not a miniature adult. After the rapidity of intrauterine growth, the human growth rate declines in the following years until a new growth spurt, typical of puberty, sets in. And it is only when sexual maturation is completed that the now fertile human being stops growing. In this sense, humans are similar to, for example, birds but different from reptiles and fish which keep growing until the end of their lives, albeit at a steadily decreasing rate. The growth process that transforms a newborn into an adult implies a very gradual change in body proportions. In a child, these can readily be defined by the interrelationship of a number of linear measurements, such as sitting height to full height, or head circumference to crown rump length. The growth of different parts of the body does not occur simultaneously or at the same speed. But at any given age, a certain correlation between measurements can be expected. We tend to take for granted the ease with which we can equate the human body’s shape with an accurate estimate of human age - whether the compactness of a five year old or the coltishness of a young teenager or the dimensions of a mature adult. Nevertheless, this feat is remarkable. Even more extraordinary is the precision with which the human eye registers any deviation from the norm. The mathematical expression of these perceptions for scientific purposes is a highly complex task with imperfect results. Vital information is lost. What we can do, however, is use a reference population to order the complexity of what even the untrained eye perceives naturally. The aim of this manual is to provide much-needed data on a reference population as a useful tool for recognizing abnormal growth patterns.

Preface to second extended edition The second edition represents an important extension of the first one because of the inclusion of velocity curves.These curves are based on the recent Maastricht growth study of 1999. The velocity curves are given for a number of anthropometric measurements and thereby offer the opportunity to get insight in the timing of growth of different parts of the body. The differences in timing are responsible for the change in body proportions on their way to maturity. Comparison of individual growth curves with these standards is essential in estimating the maturity of the child or the normality of its growth pattern. The study of the individual growth of healthy normal children also gives the opportunity to calculate expectations, by means of correlation charts, of the future growth of this individual given its present state.

Reference group
Population This manual contains reference values for a number of anthropometrical measurements. The growth curves are based on three cross-sectional studies: – The Maastricht I study: 1,518 infants; 407 born at a gestational age of 25 - 40 weeks and 1,111 full-term infants measured between 0 and 12 months of age; – The Oosterwolde I study : 2,333 children measured between 0 and 18 years of age; – The Oosterwolde II study: 620 children measured between 6 and 18 years of age for investigation of secular trend. The velocity curves are based on a semilongitudinal study: – The Maastricht II study: 1,234 full-term infants measured from birth and 2,595 children measured from 8 years onwards. Location Maastricht Founded some 2,000 years ago as a Roman town, Trajectum ad Mosum, the city of Maastricht regained economic and strategic lustre in 1991 when the basis for European unification was laid by the “Treaty of Maastricht”. The capital of the province of Limburg, Maastricht, is located in the southernmost area of The Netherlands, wedged between the Belgian and German borders. It has about 120,000 inhabitants. The principle economic activities are commerce, service and light industry. It is also the site of a major university and regional government. Oosterwolde Oosterwolde in the province of Friesland is centrally situated in the north of The Netherlands. The town of Oosterwolde and its municipal area, including a number of surrounding villages, has about 25,000 inhabitants. The principle economic activities are commerce, agriculture and light industry. Health of Children Children suspected of being growth retarded were excluded from the reference population for reasons such as: – Growth retardation of endocrine origin; – Chromosomal abnormalities and syndromes; – Growth retardation resulting from hereditary skeletal diseases; – Growth retardation due to insufficiencies of the: • Digestive and nutritional system; • Cardiorespiratory system;

Sampling Procedure The Maastricht I study population consisted of 1,518 newborns divided in 407 infants of a gestational age of 25 - 40 weeks of which 219 were boys and 188 were girls, and 1,111 full-term of which 613 were boys and 498 girls. The first group was measured between 1988 and 1994 at the neonatal unit of the Academic Hospital Maastricht, in cooperation with the Hôpital de la Citadelle at Liège, Belgium, and the Clinique St.Vincent at Rocourt, Belgium. All infants were measured between the 2nd and 7th day of life. The second group of full-term infants was measured at the Maastricht infant health-centers in their first year of life. These centers exist in all major districts of the city and cover all socioeconomic levels of the population. They routinely screen children up until age 4 to control growth, development and health. The Oosterwolde I study population consisted of 2,333 children, 1,240 were boys and 1,093 girls, ranging from birth to 18 years of age. The study was carried out from 1979 to 1980. The youngest group, age-range birth to 4 years, was measured at infant health-centers. The older group was measured both at kindergarten and at different types of schools, so as to cover all socioeconomic levels of the population. The Oosterwolde II study population consisted of 620 children. It concerns a study of the secular trend. For that reason a sample was taken in 1989 at some of the schools as in the The Oosterwolde I study. The Maastricht II study population consisted of 1,234 full-term infants of which 678 boys (55%) and 556 girls (45%) and 2,595 children of which 1349 were boys (52%) and 1246 were girls (48%). Both groups were measured between 1995 and 1999. The infants were followed at the Maastricht infant health-centers from birth until 4 years of age with a monthly interval during the first half year, every two months during the next half year and twice a year thereafter. The older children were measured twice a year. The whole population was divided in cohorts of 4 years. Assessment of Gestational Age In this study, gestational age was assessed as the time from the first day of the last menstrual period until birth. It was calculated using anamnestic information and cross-checked with information provided by the midwife or gynaecologist, who estimated the gestational age through physical investigation or ultrasound.

Assessment of Postnatal Age The age of older children was obtained through the parents or directly from the child. To ensure that this information was correct, birth dates were cross-referenced with the corresponding health-centers and schools.
Comparison with other studies The growth curves of this manual are based on three different cross-sectional studies separated by geographical areas (north and south) within The Netherlands and by an interval of 10 years. The data have not been pooled since the existence of a slight difference in height between the population of the north and that of the south within The Netherlands was established. Besides, a time interval of 10 years will be responsible for height differences because of the so called secular trend. The data of the Maastricht II velocity study of 1999 were compared with the data of the Maastricht I and the Oosterwolde I study as presented in “Paediatric Morphometrics” published in 1996. The data were also compared with the recent Dutch survey of 1997. For the different measurements all Maastricht II data were expressed as standard deviation score of the cross-sectional data. In the tables the mean and the standard deviation are given for the different age groups. Dutch study

Variables and Method of Measurement
Length and Height Introduction In paediatrics, the curve representing a child’s increase in height with age is used as one of the indicators of its health. Its height is compared to that of a reference population in order to judge whether the child is atypical in terms of the height distribution of this population. Child and reference population must share the same geographical and socioeconomic background. Also, parental or familial height should be taken into consideration to assess the relative contribution of genetic and other factors to the child’s height at any particular age. Since growth is a dynamic process, one isolated measurement in time is meaningless to judge growth. Repeated measurements are needed to calculate the growth velocity. Knowledge of growth velocity is particularly relevant when dealing with a sick child. Depressed growth velocity may indicate the severity of an illness, whereas normalization of growth velocity or catch-up growth may signal recuperation. Height is the distance between the top of the head and the sole of the foot. This distance is the sum of different parts of the body: the height of the skull, the length of the spine and the length of the lower extremities are added. Each of these different parts of the body grows at its own velocity, and is age-dependent. Therefore, height is the result of the sum of different values, which are not linearly related in time. Method of Measurement The distance between the top of the head and the sole of the foot is called length when an individual is measured lying down and height when the individual is standing upright. Height is measured using a stadiometer. The stadiometer comprises a rigid vertical backboard and a horizontal headboard running free, perpendicular to the backboard and without crossplay. The top of the head must be in contact with the headboard. A 0.5 kg weight is placed on the headboard. This serves the purpose of flattening the child’s hair and frees the physician’s hands so as to enable him to keep the child in the correct upright position. To measure standing height, shoes and socks are removed. The child is placed so that his heels, buttocks and shoulders are in contact with the vertical plane of the stadiometer. The child’s feet must be flat against the floor while either ankles or knees remain in contact. The child’s head is held in the ‘Frankfurt plane’: the lower borders of the orbits are in the same horizontal plane as the external auditory meati. The measurement is taken while a gentle upward pressure is exerted on the mastoid processes so that the child is fully extended. In older children, stretching is achieved by telling them to breathe deeply. To measure supine length, a measuring table resembling a stadiometer is used but on a horizontal plane. The headboard is fixed while the foot board is movable. Both the headboard and the foot board must be big enough to ensure that both the top of the head and the feet are in contact with them. To measure supine length two people are necessary: the infant’s head is

held in the vertical Frankfurt plane while at the same time its legs are kept straight. Shoulders and buttocks must be in contact with the table. Supine length is measured in the first two years of age.
Weight Introduction Weight as an isolated measurement provides very little information for clinical practice. When studying a particular child whose weight is apparently above normal for its age, two relationships must be considered. One is the child’s weight in relation to its height and the other is its height in relation to that of a reference population. Depending on these two variables, the child may be thin, normal or fat. Weight in relation to height can be expressed in several ways. The simplest and most informative way is to plot weight against height, using the original data. Derived values, as in the case of indices, give no information on the original measurements of weight and height. Nevertheless the Ponderal Index for infants and the Quetelet Index for older children and adults, are commonly used.
Part 1 Data collection
The Ponderal Index is expressed as 100 Ă—
Wt Lt 3
where W is weight in grams, L is length in centimeters and t is age, ranging from 25 weeks gestational age to 1 year. The Quetelet Index is expressed as Wt Lt 2 where W is weight in kilograms, H is height in meter and t is age, ranging from 0 to 18 years. In these indices, weight is considered in relation to height and accepted as normal when it corresponds to a certain age-dependent value. The concern arising from the use of these indices is that in certain situations the index may appear to be normal even though the height and weight are atypical. For example, in infants whose growth is impaired during the last weeks of pregnancy, an excessive loss of weight compared to height appears, resulting in a low Ponderal Index. In contrast, infants whose growth is affected early in pregnancy, and therefore both weight and height are affected, a normal Ponderal Index will appear though the infant may be severely growth-retarded. Method of Measurement To measure weight, the child’s outer clothing and socks should be removed. A suitable electronic scale with digital readings, accurate to a gram, is appropriate. Also, a beam balance may be used, although it is less accurate due to low precision reading.

Crown Rump Length, Sitting Height and Subischial Leg Length Introduction As stated before, height defined as the distance between the top of the head and the sole of the foot is the result of the sum of different values, which are not linearly related in time. Therefore, the first step is to split height into its different components. Generally, sitting height is taken as one of the components and compared to height. The relation between sitting height and height is often expressed as an age-dependent ratio. The use of ratios can be misleading for two reasons: first, two ratios may be equal, while their nominators and denominators are not; and second, when a change in the nominator automatically leads to a change in the denominator, the change of the ratio will be even more misleading. Therefore, a clearer approach is to simply plot height against sitting height; and an even clearer one is to use sitting height and subischial leg length as variables to compare, since a change in sitting height will not automatically induce a change in subischial leg length. Method of Measurement The distance between the top of the head and the buttocks is called sitting height when the measurement is taken of a child sitting upright and crown rump length when an infant is measured lying down. Sitting height is measured using a sitting height table. The table comprises a rigid vertical backboard and a horizontal headboard running free perpendicular to the backboard and without crossplay. The surface of the headboard must be in contact with the top of the head. A 0.5 kg weight is placed on the headboard. This weight flattens the child’s hair and also frees the physician’s hand so as to be able to keep the child in the right position. The child must be in the sitting position with his feet on a footrest so that his full weight is on his buttocks. In so far as possible, arching of the back is avoided by gently applying upward pressure to the mastoid processes. In older children, stretching of the back is achieved by asking them to breathe deeply. The child’s head is held in the ‘Frankfurt plane’: the lower borders of the orbits are in the same horizontal plane with the external auditory meati. The recommended instrument to measure crown rump length is similar to the stadiometer used for supine length. The headboard is fixed while the foot board is movable. Head board and foot board must be large enough to ensure that the most protruding points of both head and buttocks are in contact with the boards. In order to measure this length, an assistant holds the infant’s head in the vertical Frankfurt plane while the physician holds the child’s legs at a 90 degree angle with the table. When this is achieved, the foot board is pressed against the buttocks. Subischial leg length is defined as the arithmetic difference between height and sitting height or between supine length and crown rump length.

Head Circumference Introduction The head circumference is routinely measured in newborn infants since it correlates well with skull volume. Skull volume is highly correlated with gestational age, body weight and body length. Since in intrauterine growth retardation the brain is less affected than the weight and the length, the lack of a good correlation between these measurements in the newborn will signal the severity of the retardation. The growth velocity of the head circumference provides an important measure since it is fast during the first year of life. In full-term healthy newborns, the head circumference increases about 1 mm per day initially. Measurement of the growth velocity of the head may therefore be used to monitor the infant’s general condition. Method of Measurement To measure head circumference, a fiberglass reinforced tape of non- stretchable material is used. The tape is placed around the head at the most protruding points of occiput and forehead. In younger children, the tape is placed just above the brow ridges. The tape is placed gently so as to leave no marks after removal.

Limb Length Arm Span, Upper Arm Length, Lower Arm Length, Hand Length, Tibia Length and Foot Length Introduction The measurement of the limbs so as to describe body proportions is an important tool when evaluating development. Arm span is the most common way to measure upper limb length. However, by measuring the span of the out-stretched arms from the tips of the longest fingers, the distorting information of the width of the trunk is added. What is required, however, is information on the growth of the long bones alone. Furthermore, the long bones of arms and legs can be accurately measured because of its bony marks. Hand and foot mature at an earlier age than other parts of the body. Therefore, the changing relationship of hand and foot to height is a useful criterium of the maturation of the child. Method of Measurement To measure arm span, a measuring rod can be used. Standing with the arms fully extended, the distance between the tips of the stretched middle fingers is measured. To measure the different parts of the arm, the arm should be relaxed and extended along the child’s side. The bony prominences are used as anatomical landmarks: the lateral border of the acromion, the head of the radius palpated distal to the lateral epicondyle of the humerus, and the bottom of the radius. These landmarks are marked with a pen and the distance between them is measured. To measure the length of the hand, the distance between the tip of the longest finger and the bottom of the radius is measured with the hand and forearm flat on a table. For tibia length, the distance between the proximal-medial border of the tibia and the distal border of the medial malleolus is measured with the Harpenden anthropometer. The foot is measured while the child is standing. The distance between the most posterior part of the heel and the tip of the longest toe, normally the first toe, is measured on the left foot.

Biacromial Diameter and Biiliacal Diameter Introduction Puberty is characterized auxologically by increasing diameter of shoulders and hips. The ratio of biacromial diameter to biiliacal diameter is a good index of sexual maturation. Biacromial and biiliacal diameter curves remain almost identical in both sexes until puberty. The increase of the biacromial diameter during puberty is more striking in boys than in girls. The change of the ratio between biacromial and biiliacal diameter signals the onset of puberty.
Method of Measurement With the Harpenden anthropometer, measurements of shoulder widths and pelvic widths are taken. When the child relaxes its shoulders, the distance between the most lateral borders of the acromial processes is measured to obtain the biacromal diameter. To measure the biiliacal diameter, the branches of the anthropometer are moved over the iliac crests at their widest point and the distance between the two blades of the anthropometer is measured. In children aged 0-1 year, it is not always possible to take these measurements because of unrest or obesity. Also in older children, the biiliacal diameter is hard to obtain in the case of obesity.

Mid Upper Arm Circumference, Upper Leg Circumference and Calf Circumference Introduction The measurement of these circumferences is commonly used to define an individual’s nutritional status. However, because they comprise bone, muscle mass, fat mass and skin, the results lack specific information. These measurements make no distinction between an athlete and an obese individual. In order to make this distinction, the circumference must be considered in relation to skinfold thickness. The ratio of muscle and fat area in the sagital plane of the mid-upperarm must be calculated as an indicator of muscle mass. This ratio is computed based on mid-upper arm circumference (MUAC) and biceps- and triceps skinfolds. Method of Measurement To measure body circumferences, a reinforced fiberglass tape of a non- stretchable material is used. The tape is tightened gently so that no marks remain after removal. Upper arm circumference is measured while the arm is relaxed and extended along the child’s side. The tape is placed midway between the acromion and olecranon processes. Upper leg circumference is measured while the child is standing. The tape is placed around the upper-thigh in a horizontal plane at the level of the gluteal fold. Calf circumference is measured while the child is sitting on a table, its feet free from the ground and calves relaxed. The circumference is measured at its maximum.

Skinfold Introduction To estimate total body fat content, skinfolds are measured since it is assumed that nearly all body fat is in adipose tissue, mostly located subcutaneously. In this approach, the thickness of the subcutaneous fat mantle is taken as the total amount of body fat. However, in so doing, intraabdominal and intracraneal fat is not measured, though this is an important measure as well. Method of Measurement Skinfolds are measured on the upper arm midway between elbow and shoulder, in the biceps and the triceps region; for the back, at the lower tip of the scapula; and in the abdominal region over the iliac crest. The measurement is taken by grasping the subcutaneous tissue between thumb and forefinger, shaking it gently to exclude underlying muscle and stretching it just far enough to permit the jaws of the caliper to impinge on the tissue. Since the jaws of the caliper compress the tissue, the caliper reading diminishes for a few seconds and then the dial is read. These measurements are taken on the left side of the body, in agreement with the protocol of the International Biological Program.

Growth Curve To evaluate the growth of a child 'growth curves' are used. Values falling outside these growth curves are not considered normal. The word normal can be taken to mean a 'norm or standard' but it can also be taken to mean 'the typical or habitual'. It is important to realize that the norm does not always agree with the typical. A clear example can be found when the population's weight in a developing country is studied. Although the mean weight for that population is typical, it remains lower than the norm. The ideal situation occurs when the typical coincides with the norm. Construction of the charts Let the data,
{X , Y } i

n i =1
where n is the number of individuals in the sample, be sorted in ascending order, X J + 1 ≥ X j , J = 1,K, n − 1 Let S j = {X i , Yi } i = j , j = 1,K, n − k, k << n j+ k
be a subset of the data. For each subset Sj, j=1,...,n-k a series of percentiles is computed: P3, P10, P25, P50, P75, P90 and P97. The values of P25, P50 and P75 can be well estimated for moderate sample sizes. To estimate the third and 97th percentiles extremely large samples are needed. This difficulty is overcome by smoothly transforming the distribution into a two sided Gaussian distribution, the left side based on P25 and P50, the right side on P50 and P75. This transformation is approximated by a B-spline representation, the parameters of which are estimated by least squares optimization assigning virtually all weight to the values P25, P50 and P75. Back-transformation then provides smoothly changing values for the indicated percentiles for each subsequent subset, Sj. These values are plotted at x=
1 j+ k ∑x k + 1 i= j i
Connection of corresponding P-values finally completes the graphs. The standard deviations SD+ and SD− should be understood as the back-transformed standard deviation of the Gaussian distribution above or below the mean respectively. Use of charts In the tables the standaard deviations are given as +1 SD and −1 SD, the SD value above and below the P50 respectively. Calculating a z-score or SD score, one need to use the +1 SD if the
Part 2 Construction and use of charts
individuals measurement is above the P50 of the reference group, −1 SD if the individuals measurement is below the P50 of the reference group. Please note that in some cases a discrepancy may be found between table and chart. Tables are computed for all individuals ranging from 25 weeks gestational age to 18 years of age. Charts, in contrast, are based on the separate populations (Maastricht and Oosterwolde respectively).
Velocity Curve The velocity curves are constructed by numerical differentiation of individual growth curves, i.e. curves that are based on longitudinal data. The mean of the velocity curve does not characterize the average velocity curve of the population, since phase differences between individual velocity curves are not taken into account. These phase differences can be found by comparing ages, , at which pubertal peak velocity occurs. If T is the mean age at which peak velocity takes place then stretching each individual age axis by t → αt (with αTi = T, α > 0) and v → αv accordingly, provides a proper charaterization of the general average velocity curve. There are some drawbacks involved in this technique. Firstly, since the curves in the thus obtained graph are stretched, comparing them with data of some specific individual for which the age shift is unknown a priori is not completely satisfactory. Secondly, the above described technique becomes troublesome, in a numerical sense, if e.g. pubertal peak velocities are (almost) absent, as is the case for several variables. Therefore, an age transformation is applied only for the variables height, sitting height, subischial leg length and weight.
Correlation Charts Correlation coefficients may be used to predict the future z-score, Zt 1 (i), of an individual i at age t1, given its present z-score Zt 0 (i). In practice, it is often assumed that Zt 1 (i) = Zt 0 (i), i.e. the individual keeps following its percentile line. This crude approximation is systematically biased in the sense that the optimal prediction ρ(t 0 , t 1 )Zt 0 (i) of Zt 1 (i)is systematically closer to 0 (displaying the phenomenon of regression to the mean). Here, figures will be given that provide the correlation coefficients from which better estimates for the prediction of the z-score can be made. Construction of charts The correlation reads ρ(t 0 , t 1 ) = EZt 0 Zt 1 ≈
1 n ∑ Z (i)Zt 1 (i), n i =1 t 0
where the latter term is a sample analogue, n is the number of individuals indexed by i and measured at ages t0 and t1. Of course, the correlation coefficient, with

ρ(t 0 , t 1 ) > 0, ρ(t 0 , t 1 ) = ρ(t 1 , t 0 ) and ρ(t 0 , t 0 ) = 1, satisfies strictly positive definiteness properties and can be written as 1 − 12 E( Zt 0 − Zt 1 ) 2 . An impression of ρ arises by placing at all age points (t0, t1), for which Xt 0 (i) and Xt 1 (i) of some individual i are measured, the function value 1 − 12 ( Zt 0 (i) − Zt 1 (i)) 2 . These function values are approximated by exp − f (t 0 ) − f (t 1 ) , where f is a monotonously increasing (spline) function with f(0)=0. Use of charts The figure can be used as follows. Let Zt 0 (i) be given, i.e. the z-score of individual i at age t0, and our interest is in Zt 1 (i), then read from the figure ρ(t 0 , t 1 ) and find the estimate of the expectation of the z-score of individual i at age t1 as Zt 1 (i) ≈ ρ(t 0 , t 1 )Zt 0 (i) For example: a boy of 6 years old has a z-score for height of -1.5. One wants to know the expected z-score on age 8 years. From the figure “correlation height boys” the intersection point at age 6 and age 8 one finds the correlation value 0.95. Hence the expected value of height at age 8 is 0.95 × -1.5 = -1.4 SDS. It is clear from the correlation figures that the closer the curves are around the diagonal the smaller is the correlation and thereby the larger the expected change in z-scores.
Body Composition There is a theoretical relationship between the sum of four skinfolds and total body density which can be expressed through different prediction equations. To compute the fat free mass fraction, the human body is assumed to consist of two components: fat and fat-free mass. The density of fat mass is a constant: Df, is 0.9 kg/l while the density of fat-free mass depends on age and sex, Dff = Dff (age,sex). The actual fraction of fat-free mass in a human body is expressed as ⎛1 1 ⎞⎛ 1 1 ⎞ ⎜ − ⎟⎜ ⎟ − ⎝ D Df ⎠ ⎝ Dff Df ⎠
−1
where D = W/V, W is weight in kg and V is volume in liter and D represents the total body density. The total body density is estimated from four skinfolds as D = a – b log (sum skinfolds), where the skinfolds are taken at biceps, triceps, subscapular and suprailiacal sites. The parameters a and b and Dff depend on age and sex and were established by Fomon and Durnin.
Part 2 Construction and use of charts
To estimate protein content, the muscle mass is estimated by calculating the ratio of muscle area and fat area in the sagital plane of the mid-upperarm. This ratio is computed on the basis of mid-upper arm circumference (MUAC) and skinfold thicknesses. The arm muscle area is calculated by subtracting the skin area from the arm sectional area π ⎛ MUAC ⎞ ⎜ − S⎟ ⎠ 4⎝ π
2
where S is Skinfold is the mean value (mm) of biceps and triceps skinfolds. In the nomogram MUAC is given in cm and the sum of two skinfolds is used instead of the mean value. In order to make a correct estimation of the constitution the following considerations must be made. Firstly, skinfold measurements are among the least reproducable of all measurements. By averaging the measurements of four skinfolds, this problem is partly solved. Secondly, the use of the previously mentioned theoretical prediction equations introduces an oversimplification because it reduces the parameters involved. For example, a drastic increase in weight due only to water retention will not affect the thickness of the skinfold. Since the thickness of the skinfold remains the same, and in accordance with the prediction equations, it is assumed that the fraction of fat-free mass remains the same. This means that, since weight has increased, fat mass has also increased: a wrong conclusion in this case. Use of the nomogram To estimate the fraction of fat free mass one needs the following procedure. The horizontal axis represents the sum of the skinfolds at biceps, triceps, subscapular and suprailiacal sites. The vertical axis represents the fraction fat-free mass. Multiplication of this fraction by the actual weight gives the fat-free mass. To use the graph, find the sum of skinfolds at the horizontal axis and follow it until the curve of the child’s age class is crossed. From this intersection point, draw a horizontal line until the vertical axis is met and find the fraction fat-free mass. Continue the horizontal line until the 95% confidence interval of the child’s age class is reached. Each interval is trivially divided by the mean and two standard deviations or roughly the P3, P50 and P97.

Sum of four skinfolds (mm)
Use of the nomogram To estimate the fraction of fat free mass one needs the following procedure. The horizontal axis represents the sum of the skinfolds at biceps, triceps, subscapular and suprailiacal sites. The vertical axis represents the fraction fat-free mass. Multiplication of this fraction by the actual weight gives the fat-free mass. To use the graph, find the sum of skinfolds at the horizontal axis and follow it until the curve of the child’s age class is crossed. From this intersection point, draw a horizontal line until the vertical axis is met and find the fraction fat-free mass. Continue the horizontal line until the 95% confidence interval of the child’s age class is reached. Each interval is trivially divided by the mean and two standard deviations or roughly the P3, P50 and P97.
