目的:分析南宁市城市居民体重指数(BMI)与糖尿病(DM)发病的关系。方法:对南宁市样本区随机抽取五个街道社区(居委会)810户,每户抽取年龄在35~74岁的居民1人,共810人。分别检测体重、BMI、餐后12h空腹血糖(FPG);按DM糖耐量低减(IGT)诊断标准分别计算各组的患病率并对照比较。结果:DM患病率以65~74岁组最多,达14·56%;IGT患病率以55~64岁组最多,达16·28%;BMI肥胖组DM、IGT患病率均比正常体重组高,分别高出8·49%及14·48%;不同性别DM、IGT患病率比较差异无统计学意义(P>0·05)。结论:南宁市城市居民DM与IGT的患病情况随年龄增长而逐渐升高,提示超体重和肥胖是糖尿病的重要危险因素之一;糖尿病及糖耐量低减在南宁市城市居民中已占有相当大的比例。
Objective: To analyze the relationship between body mass index (BMI) and diabetes mellitus (DM) in Nanning city. Methods: 810 households of five neighborhoods (neighborhood committees) were randomly selected in the sample area of Nanning City. One household sampled 810 residents aged 35-74 years. The body weight, BMI and fasting plasma glucose (FPG) at 12h postprandial were measured respectively. The prevalences of each group were calculated according to the diagnostic criteria of IGT. Results: The prevalence of DM was highest in the 65-74 age group (14.56%). The prevalence of IGT was highest in the group of 55-64 years old (16.28%). The prevalence of DM and IGT in the BMI obesity group was higher than that of the normal The body weight was higher, which was 8.49% and 14.48% respectively. There was no significant difference in the prevalence of IGT among different sexes (P> 0.05). Conclusion: The prevalence of DM and IGT in urban residents in Nanning City gradually increases with age, suggesting that overweight and obesity are one of the important risk factors for diabetes. Diabetes and impaired glucose tolerance have a similar share of urban residents in Nanning Big proportion.
