骨质疏松症是所有西方国家的一个主要健康问题，是一种与许多饮食因素有关的疾病。为了解饮食对股骨近端骨量的影响，对159名23~75岁高加索女性的14种营养素的摄入量进行了测定，并用双光子骨密度仪测定了髋部的骨密度。用单光子吸收法测脊柱骨密度和前臂骨矿含量。目前的钙摄入量和任何部位的骨量之间都没有发现显著的相关性。通过多元回归分析，铁是股骨颈骨密度的正预测因子，酒精摄入量是绝经前妇女股骨粗隆部位骨密度的正预测因子。绝经前妇女铁、锌、镁摄入量与前臂BMC呈正相关。多元回归分析显示，铁和镁分别是绝经前和绝经后妇女前臂骨矿含量的显著预测因子。这些结果表明，骨量受饮食因素的影响，而不是钙。
Osteoporosis, a major health problem in all Western countries, is a condition in which many dietary factors have been implicated. To determine the influence of diet on bone mass in the proximal femur, the intake of 14 nutrients was measured in 159 Caucasian women, aged 23-75 years and bone mineral density (BMD) quantitated in the hip by dual photon absorptiometry. BMD was also measured in the spine and bone mineral content (BMC) in the forearm by single photon absorptiometry. No significant correlation was found between current calcium intake and bone mass at any site. Iron was a positive predictor of BMD in the femoral neck and alcohol intake a positive predictor of BMD in the trochanteric region of the proximal femur in premenopausal women by multiple regression analysis. Iron, zinc and magnesium intake were positively correlated with forearm BMC in premenopausal women. Iron and magnesium were significant predictors of forearm BMC in premenopausal and postmenopausal women respectively by multiple regression analysis. These results suggest that bone mass is influenced by dietary factors other than calcium.
