男性体检人群骨密度调查及其影响因素分析

摘要

目的 调查男性体检人群骨密度情况,并探讨骨密度的相关影响因素.方法 选取2013年1~12月自愿到四川大学华西医院健康管理中心进行体检的男性5131例,采用超声骨密度仪测定体检者足跟部骨质,根据骨密度仪计算出的T和Z值,分析年龄、血脂、体重指数对骨密度的影响情况.结果 ≤35岁组骨质疏松的患病率最低,≥70岁组骨量减少和骨质疏松患病率 (42.60%,14.08%)最高.随着年龄的增加,骨量减少和骨质疏松的检出率增加,各组间差异有统计学意义 (P<0.05).在体重过低的人群中,骨量减少和骨质疏松的患病率最高(41.65%,13.27%),在超重的人群中,骨量减少和骨质疏松的患病率最低(28.96%,2.44%),随着体重指数的增加,骨量减少和骨质疏松的患病率逐渐减少(P<0.05).血脂对骨密度的影响不大(P>0.05).结论 随着年龄的增长,骨密度逐渐下降,年龄是骨密度的危险因素,体重指数是骨密度的保护因素,血脂对男性骨密度的影响不大.%Objective To investigate the status of bone mineral density in a male health examination population and analyze the relative risk factors.Methods A total of 5,131 male health examination subjects from January 2013 to December 2013 in our cen-ter were taken as study population.Bone mineral density was measured in heel bone by ultrasonic examination and relationship among bone mineral density,age,blood lipid and BMI was analyzed.Results Among various age groups,the lowest prevalence rate of osteopo-rosis was found in ≤35 years old group while the highest prevalence rate was discovered in ≥ 70 years old group (42.60% and 14.25%,respectively).The incidence of osteopenia and osteoporosis was increased with age and the differences among the age groups were statistically significant(P < 0.05).Among various body-weight groups,the highest prevalence rate of osteopenia and osteoporosis was found in underweight people while the lowest rate was discovered in overweight people (28.96% and 2.44%,respectively).The incidence of osteopenia and osteoporosis was decreased with increasing BMI (P<0.05).There was no significant correlation between blood lipids and bone mineral density (P > 0.05).Conclusion Bone mineral density is gradually decreased as people grow older. Therefore,age is a risk factor.However,body-weight is protection factor for osteoporosis.No correlation is found between blood lipids and bone mineral density.
