摘要: ［摘要］ 目的 了解云南省农村35岁及以上居民糖尿病的患病现状及与体质指数和腰围的关系．方法 采用多阶段分层随机抽样的方法从云南省大姚县抽取2 479名≥35岁常住居民进行现场问卷调查和体格检查．结果 大姚县农村居民的糖尿病患病率为6.1%，其中男性为7.1%，女性为5.1%；男性患病率高于女性（P＜0.05）．糖尿病的患病率随年龄的增加而升高（P＜0.01），随收入的增加而降低（P＜0.01）．女性的低体重率和中心性肥胖率比男性高（P＜0.05）；低体重率和中心性肥胖率有随年龄增加而上升的趋势（P＜0.01）；中心性肥胖率随收入的增加而降低（P＜0.01）．糖尿病患病的危险性均随腰围和BMI指数的增加而增加（P＜0.01），肥胖者和中心性肥胖者患糖尿病的危险性是正常体重人群的2.285倍和2.98倍．结论 应采取措施减少肥胖和中心性肥胖的发生，从而降低糖尿病的患病率．Abstract: ［Abstract］Objective To analyze the relationship between prevalence of diabetes and body mass index （BMI） and waist circumference（WC）in rural Yunnan Province.

Males had higher prevalence of diabetes than females（P＜0.05）. Prevalence of diabetes increased with age，whereas decreased when income rising（P＜0.01）. Prevalence rates of low body weight and central obesity were higher in women than in men （P＜0.01），and decreased with income（P＜0.01）. The risk of diabetes increased with BMI and WC（P＜0.01）.Obese and central obese people had 2.285 and 2.98 times higher risk of being diabetic than their counterparts.
