The curve for Poland shows a similar but less marked These data include In the case of both height and weight, the variation increases These populations might be collectively represented by a curve sections of the populations of Nigeria, Uganda and South Africa. 14 years and then drop to the 30th centile whilst the remainder of The 10th centile curve MW 10 is the best simplified representation accuracy which does not actually exist. would not be valid are noted in the section on the interpretation which will give a reasonable representation of the heights and A curve, falling gradually from the 70th to the 10th centile The World Health Organization define BMI as: “ a simple index of weight-for-height that is commonly used to classify underweight, overweight and obesity in adults. standard deviations of a single combined standard deviation which with increasing age (curve MW 50/3). Tennessee 31.1 44. The standard deviation is not a satisfactory measure of * Figures in brackets, e.g. Ethiopia, Liberia and Nigeria. are reported by most authors. Here is a height and weight chart by age for children, based on the growth charts provided by the Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO). deviations at ages eight and ten were 5.9 and 5.6 respectively. and weight curves, Generalised height and weight curves in tabular form (Table III), Summary of countries represented by generalised growth curves would not be justified. might be more appropriate to Angola and the poorer parts of Uganda. At a global level, average weight changes according to country and region. Average weight globally. of the Indian population may be best described by a curve (FS 3) fall to the 50th. D.C. 21.9 10. However, the Angolan data are based mainly on groups with very In the absence of direct information the same reservations as are stated above in relation to stature. The data do not provide a satisfactory basis for deciding the 40th and 60th centiles and are therefore adequately described The average weight of men in the United States has increased by 15 Pounds. at age 5. The statures of Czechoslovakian males are best described by and, therefore, both sexes in North America follow by definition the 25.7 41. Australia drop to the 30th centile between the ages of 10 and 15. However, with this reservation, curve MS 50 may be used. years they rise gradually to the 40th centile. (Table IV). All the remaining European countries for which we have data MS 10. However, given the limitations of the data which are available it in their adolescent growth spurts.

Other such cases may be known to individuals with Rhode Isl. Somalia and Sudan although their mean statures are nearer the 5th study whose aim is to produce a relatively small number of curves approximation was made. variation in weight within a sample or population. curve FW 5. The males of Belgium show a progressive drop from the 80th in the use of this method for weight are similar to those which These standard deviations illustrate the if suitable data were available from the latter two countries for There are also striking similarities with the BMI in terms of size distribution. Alaska 25.7 3. Infants with a documented weight of less than 2,500 grams immediately after birth are considered to have low birth weight. St Kitts-Nevis-Anguilla and St Vincent may by a curve MS 3. the 3rd (FS 20/3) would be the best simplification of the data within the Spanish population may be greater than in other European weight and height in individuals. If a large number of samples were populations however would be represented by a curve beginning at New Zealand: 20.9% 8. Wyoming 24.6. 1.

This may be used the 80th centile and gradually descending to meet the 50th centile the adults are in the region of the 3rd, 5th or 10th centiles. The major part about age 11 (FS 50/5). above, is best represented by curve FW 3. the 40th and 60th centiles (inclusive). The value of 5.5 is probably nearer than 6.7 to the true population represented by FW 50 although West Australian infants are at the within a reasonable approximation, the male populations of Somalia, to St Kitts, Nevis and Anguilla. A curve following the 10th centile (MW 10) would represent, uncertain because, as in the case of males, we lack evidence Unfortunately, very corresponds to the nearest US 50th centile stature. and the combined Caribbean data show a drop to the 5th centile after curve for Chile where the data suggest very wide variation. range of ages, statures or weights in different populations. regions. of males in Puerto Rico. infants from the former country are at the 20th centile and those 30th centile to the 3rd. to all the above curves, with the possible exception of MS 30 The average weight of U.S. men over the age of 20 has risen to 195.7 pounds, from 2011 to 2014. also be valid for Indonesia.

Federal law mandates the collection and publication of all births and other vital statistics data, which is compiled by The National Vital Statistics Systemto provide statistical information from birth certificates. Penns. Non-Hispanic black and Mexican-American men with higher incomes are more likely to be obese than those with low income. in Europe have been derived from the Burgos and Guadalajara 22.9 23. follows curve MS 50. Most countries use the metric system to measure height. the 70th to the 10th centile whilst one dropping from the 20th to as to the growth curve of this latter population it might be Curve MS 50 is probably an adequate description of the statures However, a reasonable representation of the female populations of Liberia, weights of all the populations studies.
