A group of 160 girls of predominantly Asian and Caucasian ancestry identified from an HMO membership were examined for predictors of body fat. Girls were measured twice at a 2‐year interval during puberty. At each exam, physical activity was measured with a validated questionnaire of past year activity, dietary intake with a 3‐day dietary record, and Tanner stage was assessed clinically. A model predicting DXA trunk to periphery fat ratio (exam 2), was adjusted for METs of physical activity, kj/day (mean of exams 1 & 2), Tanner public hair stage (exam 2) and height (exam 2). Age (exam 2) and birth weight negatively predicted trunk to periphery ratio while Asian ethnicity positively predicted trunk to periphery ratio. A hundred gram of birth weight was associated with a 3 unit decrease in DXA trunk to periphery fat ratio during adolescence. Thus, infant birth weight may be important in influencing body fat distribution during adolescence and, possibly, later in life. [Supported by USDA, Grant # 9900700].
