The association between physical activity during growth and bone microarchitecture at peak bone mass.

ABSTRACT: Childhood and adolescence are critical periods for skeletal development in establishing peak bone mass (PBM), an important determinant of lifelong fracture risk. This study investigates the relationship between cumulative physical activity during growth and bone density and microarchitecture attained surrounding PBM. BMD and microarchitecture properties were obtained in 226 individuals (142 females; 84 males) surrounding PBM (aged 18-35 years) using HR-pQCT at the distal radius and tibia, and DXA at the lumbar spine and femoral neck. Physical activity during growth up to PBM was captured with the bone-specific physical activity questionnaire (BPAQ). Spearman's partial correlations, adjusted for age, height, and weight were used to determine sex-specific associations between bone properties
