目的:了解萧山区居民的肥胖流行状况及肥胖与糖尿病的关系。方法:通过自行设计问卷,采用多阶段随机整群抽样方法于2013年12月-2014年1月对萧山区6个乡镇12个村4 473名18岁以上常住居民进行问卷调查和体格检查。结果:调查人群超重肥胖患病率为49.32%(标化患病率为45.84%)。腰围身高比≥0.5的中心性肥胖患病率为49.94%。超重及中心性肥胖患病率随年龄的增大而增加,男性超重率大于女性,女性中心性肥胖患病率大于男性,差异均有统计学意义(P<0.05)。体重正常人群中,中心性肥胖患病率为20.51%,年龄和中心性肥胖是体重正常人群糖尿病风险的两个危险因素。结论:萧山区居民肥胖流行程度高,对肥胖的干预中,不能放松对正常体重人群中中心性肥胖者的干预。

Methods: From December 2013 to January 2014, questionnaires and physical examinations were conducted on 4 473 permanent residents over the age of 18 in 12 villages in 6 townships of Xiaoshan District by means of self-designed questionnaire and multi-stage random cluster sampling method. Results: The prevalence of overweight and obesity was 49.32% (standardized rate 45.84%). The prevalence of central obesity with waist circumference ≥ 0.5 was 49.94%. The prevalence of overweight and central obesity increased with age. The prevalence of overweight was higher in males than in females. The prevalence of central obesity was higher in females than in males (P <0.05). The prevalence of central obesity is 20.51% of the normal weight population, and age and central obesity are two risk factors of diabetes in normal weight population. Conclusion: The prevalence of obesity in Xiaoshan residents is high. Intervention for obesity can not relax the intervention of central obesity in normal weight population.
