目的了解河南省居民体质量指数、腰围与糖尿病患病的相关关系。方法采用多阶段随机整群抽样方法,共抽取7 588名常住居民进行问卷调查、体格测量和实验室检测。结果河南省城市居民超重率为32.04%,肥胖率为15.54%,中心性肥胖率为32.76%,随着体质量指数和腰围的增高,糖尿病患病率呈升高趋势。Logistic分析显示,体质量过轻人群患糖尿病风险比肥胖人群低3.866倍(95%CI 2.056~11.513),比超重人群低2.510倍(95%CI 1.513~8.140);中心性肥胖糖尿病患病风险是正常腰围人群的1.371倍(95%CI 1.094~1.717)。结论河南省城市居民患病情况与人体肥胖指标高度相关,应从控制肥胖入手控制糖尿病。
Objective To understand the relationship between body mass index, waist circumference and diabetes prevalence in Henan Province. Methods A total of 7 588 permanent residents were sampled by questionnaires, physical measurements and laboratory tests using a multistage randomized cluster sampling method. Results The overweight rate was 32.04%, the obesity rate was 15.54%, and the central obesity rate was 32.76%. The prevalence of diabetes increased with the increase of body mass index and waist circumference. Logistic analysis showed that the risk of diabetic patients with low body weight was 3.866 times lower than that of obese people (95% CI 2.056-1 11.513), 2.510 times lower than that of overweight population (95% CI 1.513-8.140), and the risk of central obesity was 1.371 times (95% CI 1.094-1.717) of normal waist circumference. Conclusion The prevalence of urban residents in Henan Province is highly correlated with the index of human obesity. Diabetes should be controlled from the control of obesity.
