膳食矿物质与骨密度关系调查

Effects of Daily Mineral Intake on BMD

目的 研究老年人膳食中矿物质含量对骨密度 (BMD)的影响 ,探讨防治老年骨质疏松的措施。方法 对 30 9例 6 0岁以上老人进行了膳食调查及健康检查。结果 老年女性骨矿物质含量 (BMC)和骨密度 (BMD)显著低于男性。健康老人平均每日摄入钙、锰、铜、硒的量男性均显著高于女性。OP患者与同性别健康老人每日矿物质摄入量相比 ,OP组钾、钙、镁、铁、锰、锌、磷、来源于奶的钙 (简称奶钙 )、硒摄入量均显著低于同性别健康老人组 ,BMD与钾、钙、镁、锌、铜、磷、硒、奶钙摄入量和钙磷比值均呈显著正相关。结论 膳食矿物质与BMD存在一定的关系 ,膳食钾、钙。

Objective To study the effects of daily mineral intake on bone mineral density(BMD) of old people and the measures to prevent and treat the osteoporosis.Methods The daily nutrition intake and health were investigated in 309 old people aged over 60 years,132 male aged 65 4±4 0years,177 female aged 66 7±5 8years.Results The bone mineral content(BMC) and BMD in female were lower than that in male.The daily intake of calcium,manganese,copper,selenium of health male was higher than that of health female.The daily intake of potassium,calcium,magnesium,zinc,calcium(milk)and selenium of osteoporosis case was lower than that of health people of the same sex.BMD correlation with the daily intake of potassium,calcium,magnesium,iron,manganese,zinc,copper,phospor,selenium,calcium(milk)and ratio of calcium and phosphorus assumed significant positive relation.Conclusion The was definite relation between the daily mineral intake and BMD.The lack of daily intake of potassium,calcium,zinc,tec may lead the lower of the BMD.
