OBJECTIVE:To assess preschool children's food consumption (24 ± 60 months) and relate these ®ndings to body composition at 70 AE 2 months. DESIGN: A longitudinal study of children's dietary intakes for selected nutrients and servings of dairy products. SUBJECTS: Fifty-three white children participating in a longitudinal study (2 ± 96 months) of children's food practices and growth. MEASUREMENTS: Using in-home interviews and trained interviewers, 18 days of dietary data and measured height and weight of each child at 6 month intervals were collected. Body composition was determined by dual energy X-ray absorptiometry. RESULTS: Dietary fat was 30 ± 33% of energy with saturated and monounsaturated fat intakes b 10% and polyunsaturated`10%. Adjusting for body mass index (BMI), GLM models to predict percent body fat (%BF) or grams of total fat (gTF) with mean longitudinal calcium intake (%BF: R 2 0.51, F 7.88, P`0.0001; gTF: R 2 0.51, F 9.84, P 0.0001) or total servings of dairy products (%BF: R 2 0.47, F 6.93, P`0.0001; gTF: R 2 0.47, F 8.31, P`0.0001) as independent variables gave signi®cant results. Higher mean longitudinal calcium (mgaday) intakes and more servingsaday of dairy products were associated with lower body fat. Males had signi®cantly less body fat (P 0.01) than females. CONCLUSIONS: Higher longitudinal intakes of calcium, monounsaturated fat, and servings of dairy products were associated with lower body fat.
