The prevalences of overweight and obesity among male (n=126) and female (n=170) adolescents, ages 12-18, in urban and rural areas of Trinidad was determined. Demographics, height, weight, skinfolds, dietary intake, physical activity, and sexual maturity were assessed. The overall prevalence of overweight and obesity among Trinidadian adolescents was 13.2% and 4.4%, respectively. African females had the highest rates of overweight (18.8%) and obesity (15.6%). Urban African (70.2 32.7) and mixed (66.7 24.0) girls had higher skinfolds than rural African (49.1 16.5) and mixed (45.0 12.4) girls (p<0.05). In boys, inactivity correlated with BMI (r = 0.309; p<0.01) and skinfolds (r = 0.222; p<0.05), while in girls, skinfolds were inversely correlated with accelerometer counts/minute (r = -0.389; p<0.05). Overweight and obesity rates indicate a public health concern, particularly for African females.
