Bone health, activity and sedentariness at age 11–12 years: Cross-sectional Australian population-derived study

This research used data from the LSAC to examine cross-sectional associations of children’s bone health (size, density, strength) with moderate-vigorous physical activity (MVPA) and sedentary behaviour. In early adolescence, moderate to vigorous physical activity showed associations with better bone health that, while modest, could be of population-level importance. MVPA fragmentation and sedentary behaviour duration and fragmentation seemed less important.
