老年妇女膳食营养素与骨密度相关因素研究

Daily Nutrition and BMD of Old Climacteric Women

目的 研究老年妇女膳食营养素含量对骨密度 ( BMD)的影响 ,探讨防治老年骨质疏松的措施。 方法 对177名 60岁以上妇女进行膳食调查及 BMD检查 ,其中骨密度异常妇女 ( OP) 4 8例 ,骨密度正常妇女 12 9名。 结果 骨密度正常妇女平均每日蛋白质、脂肪、膳食纤维、视黄醇、硫胺素、核黄素、Vit C、Vit E以及钾、钙、镁、锌、磷、硒、乳钙 (由乳制品提供的钙 )的摄入量均显著高于骨密度异常妇女 ,BMD与蛋白质、脂肪、膳食纤维、视黄醇、硫胺素、核黄素、Vit C、Vit E以及钾、钙、镁、锌、磷、硒、奶钙呈显著相关 ( P<0 .0 5或 P<0 .0 1)。 结论 膳食中多种营养素与妇女的 BMD存在一定的关系 。

Objective To study the effect of daily nutrition on bone mineral density(BMD) of old climacteric women and the measures to prevent and treat osteoporosis. Methods The daily nutrition and health in 177 climacteric women aged over 60 were investigated. There are 48 osteoporosis(OP) women and 129 health women. Result The results show that the daily intake of protein, fat, fiber,retinol, thiamin, riboflavin, VitC, VitE,kalium, Calcium, magenesium, zinc, selenium and calcium(in milk) of health woman group was higher than that of OP women group. The BMD of health women was higher than that of OP women. There were positive correlativity of BMD with protein, fat, retinal, thiamin, riboflavin, VitC, VitE, kalium, Calcium, magnesium, zinc, selenium and calcium(in milk). Conclusion It suggest that the effect of daily nutrition on BMD was significant. A complete and rational nutrition is needed to prevent osteoporosis.
