The purpose of this study was to examine the prevalence of overweight and report mean Body Mass Index (BMI) and percent body fat (%BF) in Black and non-Black children, 7-9 years of age. The study involved 172 students divided as follows: 56 (32.6%) Black females, 45 (26.2%) Black males, 34 (19.7%) non-Black females, and 37 (21.5%) non-Black males. Percent body fat (%BF) was determined by bioelectrical impedance analysis (BIA). Body mass index was calculated as weight (kg)/height (m)². Black females had a statistically greater BMI (19.3 ± 4.8) and %BF (25.7 ± 10.6) than all other groups. Prevalence of at-riskor-overweight and overweight for the entire sample was 20.9 % and 19.2%, respectively. In conclusion, 40.1 % of 7 to 9 year old children assessed in this study were at-riskor-overweight or overweight, and the BMI and %BF for Black females were statistically greater than the other groups.
