老年人骨密度和血脂、血液流变学的关系

The relation among bone mineral density,blood lipid and hemorheology in the aged

目的 分析老年人血脂、血液流变学与骨密度的关系 ,探讨其内在联系。方法 对 73例老年人 (其中女性 35例 ,男性 38例 ,年龄 60～ 84岁 )运用双能 X线进行骨密度测定 ,并测量其血脂与血液流变指标。结果 老年女性 L2 ～ L4、股骨颈和大转子处骨密度与胆固醇 (TC)、甘油三酯 (TG)呈正相关 ,与胆固醇呈负相关 ;老年男性骨密度与血脂之间无明显相关 (P>0 .0 5) ;老年男、女性骨密度与血液流变学之间无明显相关性 (P>0 .0 5)。结论 老年女性骨密度与血脂之间具有相关性。

Objective To probe the relation among the bone mineral density (BMD), blood lip id and hemorheology in the aged. Methods The bone mineral d ensity was determined by dual energy X-ray absortiometry (DEXA) for 73 senile p eople (35 female, 38 male, age 60-84 years), the indexes of blood lipid and hem orhelogy were also investigated. The results were analyzed with t-test and typi cal correlation. Results There was a relation between cho le sterin and bone mineral density in the female, but not in the male aged: a posit ive relation between cholesterin and BMD of L 2-L 4, neck of femur and greate r trochanter, and a negative one between triglyceride and the BMD. No associatio n was indicated between hemorheology and BMD in all the cases (P> 0.05)). Conclusions The study demonstrated a correlation between blood lipid and BMD in the senile females.$$$$
