摘　　要：目的分析体重指数BMI与骨密度的关系。方法对2395例腰椎前后位和髋部骨密度检查结果的T值与体重指数进行统计学相关回归分析。结果无论总体分析或按年龄组分析都显示骨密度T值与体重指数呈线性正相关。低体重指数者(BMI≤20)骨密度T值低于较高体重指数者(BMI>20),差异具有显著性。骨密度T值随体重指数变化在髋部较脊柱更明显。结论体重指数与骨密度T值呈正相关,低体重指数与骨质疏松的发生有关。Objective To analyze the relationship between body mass index(BMI )and bone mineral density.Methods There is a regression analysis relating to sta tistics,according to examination f or 2395cases result of lumbar verteb rae A -P position,hip bone mineral density' s T score and body mass index.Results The T score of subjects with low BMI (BMI ≤20)is lower than relative higher ones(BMI>20),significant differences were found between two groups.Effect of body mass index on bone mineral density is more obvious in hip than in lumbar vertebrae.Conclusion As a result,there is a linearity positive correlation between bone mineral density T score and body mass index,regardless whole analysis or analysis by age groups.
