目的：了解40岁以上人群糖尿病（DM）的患病情况。方法：根据WHO诊断标准，采用葡萄糖氧化酶法测定血糖。结果：（1）DM患病率13．73％，糖耐量低减（IGT）患病率为7．84％；（2）OM和IGT患病率随年龄、体质指数（BMI）、腰臀比值（WHR）增长而增加：（3）OM和IGT组的血压均高于对照组P＜0．05：（4）有阳性家族史者DM患病率是阴性史者的3．26倍；（5）DM患者中47．26％已出现并发症。结论：IGT、年龄、肥胖、高血压、家族史是Ⅱ型DM的主要危险因素。为减少日趋增长的DM患病率，应积极开展DM的三级预防。
Objectives: To understand the prevalence of diabetes mellitus (DM) in people over the age of 40. Methods: According to WHO diagnostic criteria, glucose oxidase method was used to measure blood sugar. Results: (1) The prevalence of DM was 13.73% and the prevalence of IGT was 7.84%. (2) The prevalences of OM and IGT varied with age, body mass index (BMI) (WHR): (3) The blood pressure of OM and IGT group was higher than that of the control group (P <0.05). (4) The prevalence of DM in positive family history was 3.26 times of the negative history; (5) 47.26% of DM patients had complications. Conclusion: IGT, age, obesity, hypertension and family history are the major risk factors of type. In order to reduce the increasing prevalence of DM, tertiary prevention of DM should be actively carried out.
