2260例成年男性骨质疏松症危险因素分析

【目的】了解本地区成年男性各年龄段骨密度（BMD）的变化情况和骨质疏松症（OP）的发生率及其相关危险因素。【方法】采用美国L unar公司的双能X线骨密度仪对2260例成年男性进行腰椎L 2～4和髋部BMD测定。【结果】男性BMD峰值在25～29岁，30岁后随年龄增加而降低；超重组和肥胖组的BMD显著高于正常体质量组（ P ＜0．05）。消瘦组各部位BMD显著低于正常体质量组（ P＜0．05）。年龄、高钙饮食、体质量指数及锻炼作为OP的风险因子，OR值分别为1．07，0．945，0．849，0．494。OP发生率随着年龄的增长而增高（ P ＜0．05）。【结论】成年男性BMD随年龄增长而降低，OP的发生率也随之增加；高钙饮食、体质量指数及锻炼是OP的保护性因素，而年龄是OP的危险因素。

Analysis of the Risk Factors of 2260 Adult Male Patients with Osteoporosis

Objective]To understand the change of bone mineral density （BMD） ,the incidence rate of osteoporo-sis（OP） and its relative risk factors among adult men in local area .Methods]BMD of L2~4 and hip of 2260 adult men were measured by American Lunar dual energy X-ray absorptiometry （DEXA） .Results] The peak value of BMD in men were seen in 25~29 years old ,and decreased with the increasing of age after 30 years old .BMD in o-verweight group and obesity group were markedly hither than that in normal weight group （ P〈0 .05） .BMD in ema-ciation group was markedly lower than that in normal weight group （ P〈0 .05） .Age ,high-calcium diet ,body mass index and exercise were the risk factors of OP .The values of OR were 1 .070 ,0 .945 ,0 .849 and 0 .494 ,respective-ly .The incidence rate of OP increased with age（ P〈0 .05） .Conclusion]BMD in adult men decreases with the in-creasing of age ,and the incidence rate of OP increases with age .High-calcium diet ,body mass index and exercise are the protective factors of OP ,but age is the risk factor of OP .
