Smoothed Percentage Body Fat Percentiles for U.S. Children and Adolescents, 1999-2004. NHSR, Number 43. November 9, 2011

摘要

The high prevalence of obesity (defined by body mass index) among children and adolescents in the United States and elsewhere has prompted increased attention to body fat in childhood and adolescence. This report provides smoothed estimates of major percentiles of percentage body fat for boys and girls aged 819 years in the United States. Percentage body fat was obtained from whole-body, dual-energy x-ray absorptiometry (DXA) scans conducted during the 19992004 National Health and Nutrition Examination Survey. A nonparametric double-kernel method was employed to smooth percentile curves for the DXA data.
