“…Using sensitivity to height and age as a guide, HBSI appears to be superior to PI in reflecting body shape changes in children 5-18 years old. Our data support the opinion that PI may be useful, particularly in the analysis of different populations irrespective of sex, location and time (24,25,26,3,7,23). In the case of a population of children of both sexes, the combined HBSI could be beneficial to healthcare professionals.…”

“…A slight decrease of PI with body height, which was not statistically significant, has been reported previously (13,7). The results of this study indicate that PI decreases as a function of height at approximately twice the rate of HBSI values.…”

“…Quételet introduced body mass index in adults as BMI = M/H 2 (7). Use of BMI is justified in adults because an increase in body dimensions can occur only in two dimensions, whereas in children, growth occurs in three dimensions.…”

“…The body mass index (BMI) is defined as BMI=M/H 2 . (1,2) In children, the BMI increases during development (3,4,5,6,7). Growth charts, percentile and z-score analyses are used to classify an individual in relation to a non-disabled population, but comparison between different populations is complex (8,9,10,11).…”

Objectives-To test the assumption of geometrically similar growth by developing experimentally derived models of human body growth during the age interval of 5-18 years; to use the derived growth models to establish a new Human Body Shape Index (HBSI) based on natural age related changes in HBS; and to compare various metrics of relative body weight (body mass index, ponderal index, HBSI) in a sample of 5-18 year old children.Study design-Non-disabled Polish children (N=847) participated in this descriptive study. To model growth, the best fit between body height (H) and body mass (M) was calculated for each sex with the allometric equation M= m i H χ . HBSI and HBSI were calculated separately for girls and boys, using sex-specific values for χ and a general HBSI from combined data. The customary body mass and ponderal indices were calculated and compared to HBSI values.Results-The models of growth were M=13.11H 2.84 (R 2 =.90) and M=13.64H 2.68 (R 2 =.91) for girls and boys respectively. HBSI values contained less inherent variability and were influenced least by growth (age and height) than customary indices.Conclusion-Age-related growth during childhood is sex-specific and not geometrically similar. Therefore, indices of human body shape formulated from experimentally derived models of human growth are superior to customary geometric similarity-based indices for the characterization of human body shape in children during the formative growth years.
