African women - Bone mineral density - Fat mass - Fracture risk - Lean mass
Objectives: To examine the association between body composition (fat mass, lean mass and body mass index, BMI) and bone health (bone mineral density, BMD and fracture risk) in urban black South African women. Design: A cross sectional study examining associations between body composition, dietary intake (food frequency questionnaire), habitual physical activity (Activity energy expenditure (AEE) measured using an accelerometer with combined heart rate monitor and physical activity questionnaire) and bone health (BMD using dual-energy X ray absorptiometry, DXA and fracture risk). Setting: Urban community dwellers from Ikageng in the North-West Province of South Africa. Participants: One hundred and eighty nine (189) healthy postmenopausal women aged ≥43 years. Results: Fat mass and lean mass were significantly associated with BMD and fracture risk when adjusted for potential confounders. However, lean mass and not fat mass remained significantly associated with femoral neck BMD (β = 0.49, p
