吸烟减低西藏藏族男性骨密度

Smoking reduces bone mineral density of Tibetan males in Tibet

目的:探讨吸烟对西藏藏族男性骨密度的影响.方法:采用整群随机的抽样方法选取拉萨地区20~60岁藏族男性为研究对象,按年龄分为低年龄组(20~39岁)和高年龄组(40~60岁).利用问卷对其吸烟情况进行调查,再利用超声骨密度测定仪对研究对象的T值、骨强度指数和骨折风险进行测定.共获得有效样本378例,其中低年龄组共172例(吸烟107例,非吸烟65例)、高年龄组共206例(吸烟94例,非吸烟112例).结果:低年龄组中吸烟组与非吸烟组T值、骨强度指数差异有统计学意义,高年龄组中吸烟组与非吸烟组的T值、骨强度指数、骨折风险差异有统计学意义.结论:吸烟对人体骨密度的含量有影响,会使骨密度的含量降低,骨折风险增加.

Objective:To investigate the effect of smoking on bone mineral density of men in Tibet.Methods:A cluster random sampling method was used to select 20-60-year-old Tibetan males in Lhasa area.According to their age,they were divided into two groups:lower age group(20-39 years old)and higher age group(40-60 years old).The smoking status was investigated by questionnaire,and then the T value,bone strength index and fracture risk of the subjects were measured by ultrasonic bone mineral density measurement instrument.A total of 378 effective samples were obtained,including 172 cases in the lower age group(107 smoking and 65 non-smoking)and 206 in the high age group(94 smoking and 112 non-smoking).Results:There were significant differences in T value and bone strength index between smoking group and non-smoking group.T value and bone strength index of smoking group and non-smoking group in high age group were significantly higher than those in non-smoking group.The difference of fracture risk was statistically significant.Conclusion:Smoking can reduce bone mineral density and increase the risk of fracture.
