OBJECTIVES: To examine the association between body composition (fat mass, lean mass and body mass index, BMI) and bone health (bone mineral density, @entity1555 and @entity174 risk) in urban black South African @entity1 . 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 ( @entity1555 using dual-energy X ray absorptiometry, DXA and @entity174 risk). SETTING: Urban community dwellers from Ikageng in the North-West Province of South Africa. @entity1 : One hundred and eighty nine (189) healthy postmenopausal @entity1 aged >= 43 years. RESULTS: Fat mass and lean mass were significantly associated with @entity1555 and @entity174 risk when adjusted for potential confounders. However, lean mass and not fat mass remained significantly associated with femoral neck @entity1555 (b = 0.49, p <0.001), spine @entity1555 (b = 0.48, p< 0.0001) and hip @entity1555 (b = 0.59, p< 0.0001). Lean mass was also negatively associated with @entity174 risk (b = -0.19 p =0.04) when both lean and fat mass were in the same model. CONCLUSION: Lean mass and fat mass were positively associated with femoral neck, spine and hip BMDs and negatively associated with @entity174 risk in urban black South African @entity1 . Our finding suggests that increasing lean mass rather than fat mass is beneficial to bone health. Our study emphasises the importance of positive lifestyle changes, intake of @entity460 from dairy and adequate weight to maintain and improve bone health of postmenopausal @entity1 .
