兰州市社区中老年人群糖尿病患病情况调查

Survey on the prevalence of diabetes among the middle aged and elderly population of communities in Lanzhou

目的 了解兰州市中老年人群糖调节受损（IGR）和糖尿病的患病情况. 方法 整群随机抽取兰州市城关区张掖路及广武门街道社区40～75岁常住居民3990例,分别进行问卷调查、体格检查和糖尿病相关生化检测. 结果 IGR患病率32.6％（标化患病率32.0％）,男、女患病率分别为31.4％、33.0％（x2=0.950,P＞0.05）;糖尿病患病率28.9％（标化患病率28.4％）,男、女患病率分别为35.1％、26.6％（x2=89.378,P＜0.001）;糖尿病患者年龄较IGR患者偏大,血脂、体质指数、收缩压水平高（均P＜0.05）.IGR患病危险因素有年龄、体质指数、高三酰甘油血症、低高密度脂蛋白血症、高血压,糖尿病患病危险因素有男性、年龄、体质指数、腰臀比、高三酰甘油血症、低高密度脂蛋白血症、高血压（均P＜0.05）. 结论 兰州市城区中老年人群IGR和糖尿病患病率高于全国同年龄段的平均水平,应加强IGR和糖尿病的早期筛查和管理,以控制糖代谢异常的流行.

Objective To investigate the prevalence of impaired glucose regulation （IGR） and diabetes mellitus among the middle aged and elderly population of communities in Lanzhou.Methods We selected 3990 permanent residents aged 40-75 years in two communities in Chengguan district of Lanzhou,and each of the participants received the questionnaire survey,anthropometric measurements and diabetes related biochemical examination.Results The prevalence of IGR was 32.6%,with 31.4% in male and 33.0% in female（x2 =0.950,P〉0.05）.The prevalence of diabetes was 28.9%,with 35.1% in male and 26.6% in female（x2 =89.378,P〈0.001）.The age-and sex-adjusted prevalence of IGR and diabetes were 32.0% and 28.4%,respectively.As compared with IGR subjects,diabetes patients were older and had the greater levels of blood lipids,body-mass index and systolic blood pressure （all P〈0.05）.Age,body-mass index,high triglycerides level,low HDL cholesterol level,hypertension were the risk factors for IGR,and gender,age,body-mass index,waist-hip ratio,high triglycerides level,low HDL cholesterol level,hypertension for diabetes （all P〈0.05）.Conclusions The prevalences of IGR and diabetes among the middle aged and elderly residents are higher in Lanzhou urban communities than the national average level in the same age.We should enhance the early screening and management of IGR and diabetes to control the prevalence of abnormal glucose metabolism.
