Abstract

CONTEXT: There is evidence that sex differences in hip structure are increased during puberty, possibly as a consequence of associated changes in body composition. OBJECTIVES: The objective of the study was to explore relationships between sex, puberty, hip structure, and body composition. DESIGN/SETTING: The design was a longitudinal birth cohort study: The Avon Longitudinal Study of Parents and Children. PARTICIPANTS: Participants included 3914 boys and girls (mean age 13.8 yr). OUTCOME MEASURES: Measures included dual-energy x-ray absorptiometry-derived femoral neck width (FNW), cortical thickness (CT), bending strength [cross-sectional moment of inertia (CSMI)], section modulus, buckling ratio (BR), and femoral neck and total hip bone mineral density. RESULTS: FNW, CT, and CSMI were higher in boys, whereas BR was lower in girls (P
