体重指数和腰臀比值与糖耐量低减患病率关系

Study on relationship between BMI,WHR and prevalence rate of IGT

目的 探讨社区人群体重指数 (BMI)和腰臀比值 (WHR)与糖耐量低减 (IGT)患病率的关系。方法 采用分层整群抽样方法 ,对遵义市部分 40岁以上的中老年人进行IGT流行病学现况调查。结果 社区人群IGT患病率为 7 1 6 % ,男女IGT患病率分别为 8 34 %及 6 2 9% ,均随体重增加而增加 (P <0 0 0 1 ) ;不同BMI人群的IGT患病率不同 ,超重组和肥胖组的IGT患病率高于正常体重组 (P <0 0 0 1 ) ,RR分别为 2 0 9和 2 41 ,95 %CI分别为 1 47～2 97和 1 68～ 3 47;肥胖体型组IGT患病率高于正常体型组 (P <0 0 0 1 ) ,RR =1 87,95 %CI为 1 39～ 2 52。结论 肥胖 (尤其是腹部型肥胖 )对糖耐量低减患病率有影响 ,必须加强社区中老年人体重的干预和预防。

Objective To explore the relationship between BMI,WHR and the prevalence rate of IGT in Zunyi,so as to provide scientific informations of IGT for prevention and control.Methods The persons aged 40 and older in Zunyi,were investigated by stratified cluster sampling method.Results The crude prevalence rate of IGT in the whole population was 7 16%.The prevalence rate of IGT in both sexes were 8.34% and 6.29% respectively and increased paralelly with weight ( P <0 001).The IGT prevalence rate of different BMI in community population had a marked difference.The prevalence rate of IGT in overweight and obesity groups were signifcantly higher than in normal weight group ( P <0 001).Their relative risk(RR) were 2.09 and 2.41 respectively,their 95% confidence interval (CI) were 1.47-2.97 and 1.68-3.47 respectively.The prevalence rate of IGT in obesity of abdominal type group was signifcantly higher than in normal body type group ( P <0 001),RR=1 87,95%CI was 1.39-2.52.Conclusion Obesity(especially in obesity of abdominal type) affected the prevalence rate of IGT,prevention and intervention of body weight were in urgent need in the middle-aged and elderly.
