Objective. In our quest to accurately predict whole‐body and regional body composition changes in growing children we needed to determine whether male and female fat accumulation patterns were similar in growing children. Methods. Regional body composition data published by the U.S. Dept. of Health & Human Services Center for Disease Control was utilized and analyzed by comparing the percentage of body fat accumulated in arm, leg, trunk and head regions of the body for 8‐11, 12‐15, and 16‐19 year old males and females as determined by DEXA. Linear regression and correlations were used to identify trends in fat accumulation patterns using group average data as well as body mass‐ranked data from each group. Results. Average body fat percent decreases in males and increases in females with age. Using age‐group average data regional fat patterns are similar for males and females. However, comparisons of age group body mass ranked‐data determined that the observed range of the percent of body fat in the arm region decreases with age while there is an observed increase in the percent of body fat that occurs in the trunk region. Older males also have much lower percent of body fat in the leg region. Conclusions. Post‐puberty fat patterns are different for male versus female children. Future DEXA studies should further distinguish chest, mid‐torso/waist, and hip/buttock distribution in trunk region.
