骨质疏松的危险因素研究

Study on the risk factor of osteoporosis in Beijing

目的探讨年龄、性别、运动对骨密度的影响。方法用MetriscanX线骨密度检测仪测定200例25～74岁的人群非优势手第二，第三、第四手指中间指骨的骨密度，记录性别、年龄、平时运动情况，并进行统计学分析。结果高龄、不运动者较低龄和运动差异有显著性，65～75岁组骨质疏松的发生率最高，达47．3％。女性指骨骨密度的高峰在20～30岁，女性在60～75岁期间骨密度下降比男性快，男性指骨骨密度的高峰在40～50岁。结论高龄、不运动是骨质疏松的风险因素。

Objective To study the influence of age, gender, physical activity on the bone mineral density. Methods Measure and analyze phalangoal BMD （MP2-4） of the non-dominant hand of 200 cases with their age, gender, and physical activity. Results The BMD of old age is significantly lower than others. The BMD of the people doing less physical activity is significantly lower than those of the people exercising more. In the male group, the peak value of phalangoal BMD （MP2-4） of the non-dominant hand occurred between the age of 40-50 years, In the female group, the peak value of phalangoal BMD （MP2-4） of the non-dominant hand occurred between the age of 20-30 years, but sharply after 60 years old descended. The highest rate of osteoporosis occurred between the age of 65-75 years. Conclusion Age and less physical activity are the risk factors for osteoporosis.
