Interpretive Summary:

Technical Abstract: The present study addresses US National concerns regarding body fatness and current or subsequent health by providing national distributions of levels of body composition in the US for non-Hispanic Whites, Blacks and Mexican American populations using data from the third National Health and Nutrition Examination Survey (NHANES III). In this survey, bioelectrical impedance (BIA) data at 50 kHz were collected, but not body composition. Prediction equations for fat-free mass (FFM) and total body water (TBW), developed for independent sets of BIA and body composition data (Buo et al, under review), were applied to NHANES III BIA data to estimate FFM for each participant. Values for TBF and %BF were computed form the estimated FFM. To construct the age-, sex-, and race-specific US national distributions for body composition, NHANES III participants were separated into 13 age groups, i.e., 2-year intervals from 12 to 20 years, and at 10- year intervals from 20 to 80 years. The sampling weights for each individual were included in the calculations to account for individual selection probabilities and to adjust for non-response, non-coverage, and post-stratification that result form the complex sampling design of NHANES III. The findings indicated that (1) there were age-related increasing trends in means for TBF and %BF form 12 to 60 years, (2) means for TBF in females were largest in Blacks, then Mexican-Americans, the Whites at almost all ages, but there was little ethnic difference in males, and (3) Mexican American and Black females had larger means for %BF compared with Whites at almost all ages as did Mexican-American males compared with Black and White males.
