Objectives: Children who fracture have lower bone mineral density (BMD) measured by dual energy X-ray absorptiometry (DXA) than children who do not sustain fractures, but there is little data on bone microarchitecture in relation to childhood fracture. We assessed tibia microarchitecture using high resolution peripheral quantitative computed tomography (HR-pQCT) in children with recent fracture and those without a history of fracture.Methods: Children ag...

Objectives: Weight bearing physical activity (PA) is thought to be beneficial to bone mineral accrual in childhood, but the influence of PA and sedentary time on bone microarchitecture is less well described. We examined the relationships between self-reported PA and volumetric bone mineral density (vBMD) and bone microarchitecture at the distal tibia, assessed using high resolution peripheral quantitative computed tomography (HR-pQCT).Methods: Healthy c...
