体重、体重指数、腰围、腰臀比对绝经后2型糖尿病患者骨密度的影响

目的 探讨体重、体重指数(body mass index,BMI)、腰围、腰臀比等指标对绝经后2型糖尿病患者骨密度的影响.方法 采用双能X线骨密度仪测量162例绝经后2型糖尿病患者不同部位的骨密度,按年龄分两组(A组:＜60岁;B组:≥60岁),同一年龄段按体重指数各分为两组(L-BMI组:BMI＜25 kg/m~2;H-BMI组:BMI≥25 kg/m~2)进行分析.结果 H-BMI组多部位骨密度明显高于L-BMI组(P＜0.05或P＜0.01).年龄与骨密度呈负相关,体重与骨密度呈正相关.结论 体重及体重指数均与骨密度相关,其中体重是影响绝经后妇女骨密度的重要因素.

The effect of body weight, body mass index, waistline and waist-hip ratio on bone mineral density in postmenopausal women with type 2 diabetes

Objective To investigate the effect of weight, body mass index (BMI), waistline and waist-hip ratio (WHR) on bone mineral density (BMD) in postmenopausal women with type 2 diabetes.Methods BMD at various skeletal sites was measured by dual energy X-ray absorptiometry in 162 postmenopausal women with type 2 diabetes, and all women were divided into two groups (L-BMI group: BMI＜25 kg/m~2, H-BMI group: BMI≥25 kg/m~2) according to their BMI in different age(goup A:＜60year, groupB:≥60 year). Results The BMD at various sites in H-BMI group was higher than those in L-BMI group(P＜0.05 or P＜0.01). A negative correlation was found between age and BMD, while a positive correlation was found between weight and BMD.Conclusion Both weight and BMI are related to BMD, and weight is one of most important factors affecting BMD.
