“…Horlick et al, however, did not find any significant difference in fat mass between pubertal stages, but did find a decrease in fat mass at B3 (26). This is in contrast with our work and the work of Goulding and Rico (1,25). This difference might be due to the cross-sectional design and the smaller groups.…”

“…This is in line with other research with the DXA scan (1,25). Goulding et al found the increase in fat mass in early puberty (B1-B2 and B3-B4) also significant, but they did not adjust for height and weight (25).…”

“…From these studies we can conclude that the distribution and development of fat mass is different in boys and girls (1)(2)(3)(4)(5)(6). The current obesity epidemic urges us to learn more about the physiologic development of fat mass during puberty, a critical period in body composition development.…”

Puberty is a critical period in body composition development. The influence of puberty on the development of fat mass asks for further investigation. We investigated the development of fat mass during puberty in a longitudinal prospective study in 152 healthy nonobese white girls, initial ages between 9 to 12 years. The influence of menarcheal age and the existing of tracking of fat mass have been analyzed. In 10 years time, participants were measured on eight time points. Various anthropometric data were collected, breast development was staged according to Tanner and body composition was determined with the dual‐energy X‐ray absorptiometry (DXA) scan. Calculations were made with the use of a linear mixed model. Fat mass increases from 7.9 kg (23.6%) at B1 to 18.5 kg (29.3%) at B5. Fat mass is higher in girls with an early menarche than in girls with a late menarche from B2. Girls in the quartile with initially the lowest fat mass have a chance of being in the same quartile after 10 years of 77% (P < 0.001). Girls in the quartile with initially the highest fat mass, have a risk of staying in the highest quartile of 55% (P < 0.001). Menarcheal age is of great influence on the development of fat mass. Girls with an early menarche, will have a bigger fat mass, especially at the end of puberty. Tracking of fat mass exists: a high amount of fat mass in early puberty will continue to exist at young adulthood.

“…In females, no ageadjusted (after adjustment for the effects of age) differences in fat mass were found when comparing pre-and postmenarche girls (taking only into account the age of menarche). This result is consistent with those of other researchers who employed the Tanner stages (Teixeira et al, 2001), but is opposed to the findings of Rico et al (1993). Hammami et al (2003) found an independent gender effect on soft tissue body composition in neonates studied using DXA.…”

“…Subsequent studies to assess TBFM and muscle accumulation in prepubertal children using DXA yielded conflicting results. Some investigators observed no gender-related differences in body composition (Rico et al, 1993;Cowell et al, 1997). Others reported that girls had more fat and similar muscle mass (Ogle et al, 1995;Molgaard and Fleischer Michaelen, 1998;Johnson et al, 2001).…”

Background/Objective: The aim of this study was to describe the evolution of total and regional fat mass according to gender, and to establish age and gender-related differences in a largely non-obese sedentary Spanish sample population using dualenergy X-ray absorptiometry (DXA). Subject/Methods: A total of 1113 healthy subjects (397 male and 716 female) from the city of Alcalá de Henares (Madrid), Spain, were used in the study. Fat mass measures were obtained from DXA scans of all subjects. Total body fat and body fat in three subregions (trunk, arms and legs) were evaluated. Results: As opposed to males, females showed from early infancy a smaller rate of muscular mass and a larger percentage of body fat (from 10 years of age), with fat deposits being basically gynoid or peripheral. With age, females showed a greater increase in fat mass together with an accelerated loss of muscular mass. Both rates tended to level out between 51 and 65 years of age. Between the ages of 40 and 60, females exhibited significant morphological evidence of larger fat depots in their legs. Conclusions: Gender differences in the patterns of proportion and distribution of body fat, as well as in the pattern of body fat evolution, were found from early infancy. Further research is required, including assessing fat mass variables in order to unravel the dynamic of body composition and to understand the complex relationship between trunk fat mass deposits and the health risks associated with obesity.

The primary objective was to investigate the influences of ethnicity and pubertal stage on the ability of body mass index (BMI) to rank adiposity in a cohort of 402 Asian, African, Hispanic, and White Americans, aged 9–25 years. BMI was calculated from measured weight and height. Body composition and pubertal stage were determined by dual energy x‐ray absorptiometry and self‐rating, respectively. Multiple linear regression models with BMI, ethnicity, puberty, and age as explanatory variables were used to determine if ethnicity and pubertal stage modify the ability of BMI to predict percent of body weight that is fat (%BF). Spearman's correlation coefficients of BMI with %BF were also estimated. Both ethnicity and pubertal stage interacted with BMI. The correlation between BMI and %BF (r) was much higher in females (r = 0.72, P < 0.001) than in males (r = 0.15, NS). Among females, correlations did not vary much by pubertal stage, but tended to be higher in Blacks. Among males, correlations tended to be low during mid‐puberty. However, a high correlation between BMI and lean body mass (LBM) was consistently observed in mid‐pubertal males across all ethnic groups. Stratification by quartile of BMI showed that the correlation was >0 (P < .05) only in the highest quartile. Thus, in an ethnically diverse cohort of 9–25 year olds, the correlation between BMI and %BF is poor in the lower quartiles of BMI. In comparison, LBM correlates better with BMI than %BF in the lower quartiles of BMI. © 1996 Wiley‐Liss, Inc.
