廊坊地区部分人群骨密度调查分析

目的调查廊坊地区部分人群的骨密度情况,了解相关影响因素对廊坊地区部分健康人群骨密度的变化规律和骨量减少、骨质疏松的发病影响。方法双能X线骨密度仪对中国石油天然气集团公司中心医院1298名体检者右前臂中远1/3处进行骨密度测量,其中男性382名,女性916名,年龄40~76岁,平均年龄53.3±22.7岁,全部数据按性别、年龄分组输入电脑,采用SPSS13.0统计软件,按10岁为1个年龄组,分析各组的骨密度,分析骨质疏松的发病情况,组间比较采用t检验,取P0.05为有统计学意义。结果体重指数、牛奶、豆制品可以对骨密度起到一定的保护作用,吸烟、饮酒等日常生活习惯可以导致骨密度降低。结论体重指数、日常生活习惯、饮食、规律的运动都可以影响骨密度。

Investigation and analysis of bone mineral density in partial population of Langfang region

Objective To investigate the bone mineral density (BMD) in partial population of Langfang region, and to understand the relevant factors of the BMD variation and pathogenesis of osteoporosis in healthy people in Langfang. Methods BMD of the left distal 1/3 radius was measured in 1298 volunteers, including 382 men and 916 women, aging from 40 to 76 years old, with a mean of 53.28 ± 22.71 years old, using dual energy X-ray absorptiometry. All the data were divided in groups according to gender and age and analyzed using a SPSS 10.0 statistical software. BMD and the incidence of osteoporosis were analyzed according to 10-year-age division. Data between groups were compared using t test. The P value lower than 0.05 was considered statistically significant. Results BMI, milk, and soy played a protective role in BMD. Smoking and drinking led to a decrease of BMD. Conclusion BMI, daily habits, diet, and regular exercise can affect BMD.
