目的了解中老年人群超重肥胖和中心性肥胖与糖尿病的关系,为制定肥胖和糖尿病的防治措施提供科学依据。方法采用整群抽样方法抽取天津市某区某镇2969名45岁及以上常住居民进行调查,测量身高、体重、腰围以及血糖等。结果 2969人中糖尿病患者392人,患病率为13.2%,标化患病率为12.2%。随体质指数(BMI)增高,糖尿病患病率上升,正常体重、超重、肥胖和中心性肥胖人群糖尿病患病率分别为10.8%、15.8%、18.8%和14.9%。单因素Logistic回归分析结果显示,超重、肥胖者和中心性肥胖者患糖尿病的OR值(95%CI)分别为1.552(1.216～1.981)、1.914(1.420～2.579)和3.468(2.248～5.350),经年龄、性别和糖尿病家族史调整后,超重、肥胖和中心性肥胖与糖尿病的关系仍然存在,其OR值(95%CI)分别为1.410(1.090～1.824)、1.605(1.172～2.200)和2.559(1.547～4.233)。结论超重肥胖和中心性肥胖与中老年糖尿病患病有关,超重肥胖者和中心性肥胖者患糖尿病危险增加。
Objective To understand the relationship between overweight and central obesity and diabetes in middle-aged and elderly population and to provide a scientific basis for the prevention and treatment of obesity and diabetes mellitus. Methods A total of 2969 45-year-old and above residents in a certain district of Tianjin were sampled by cluster sampling method to survey height, weight, waist circumference and blood sugar. Results Among 2969 people, 392 were diabetic patients, the prevalence was 13.2% and the standardized prevalence was 12.2%. With the increase of body mass index (BMI), the prevalence of diabetes increased, and the prevalence of diabetes in normal weight, overweight, obesity and central obesity were 10.8%, 15.8%, 18.8% and 14.9%, respectively. The results of univariate Logistic regression analysis showed that the odds ratios (95% CI) of overweight, obesity and central obesity were 1.552 (1.216-1.981), 1.914 (1.420-2.579) and 3.468 (2.248-5.350), respectively The odds ratios (95% CI) were 1.410 (1.090-1.824), 1.605 (1.172-2.200) and 2.559 (1.172-2.200), respectively, when the relationship between overweight, obesity and central obesity and diabetes still existed after adjustment for age, sex and family history of diabetes. (1.547 ~ 4.233). Conclusion Overweight and central obesity are related to the prevalence of diabetes in middle-aged and elderly people. Overweight and central obesity patients have an increased risk of diabetes.
