The purpose of this study was to investigate the association between dietary intakes, body composition and sexual maturation among Korean girls. The subjects were 743 children aged 7 to 13 years old enrolled in elementary schools in Seoul, Korea. Subjects' dietary intakes were evaluated by 3‐day food records. Body compositions were measured by bio‐impedance analyzer and sexual maturation was assessed by self‐evaluation according to Tanner's standard photographs. Both children and parents completed a structured questionnaire. Girls were divided into Stage=1 and Stage ≥ 2 groups based on the maturation stages of breast. Girls with Stage ≥ 2 had significantly higher height, weight, body fat percentage, and body mass index (p<0.0001). There were significantly higher intakes of lipid and cholesterol (p<0.05) as well as meats and eggs intakes (p<0.05) in Stage ≥ 2 group. However, there were no significant differences in frequencies of processed foods intake between two groups. These results suggest that high intake of animal food containing lipids may accelerate sexual maturation among girls. Further studies are necessary to identify links between dietary pattern and sexual maturation using a large prospective cohort.
