天津市社区成年肥胖人群糖尿病患病率和危险因素分析

目的 研究天津市社区成年肥胖人群2型糖尿病(T2DM)患病率及其危险因素.方法 2006年在天津市采用分层整群随机抽样方法抽取全市3个城区和3个郊县≥18岁的成年人进行现况调查,从中选取体重指数(BMI)≥28 kg/m2的人群,共2888人作为研究对象.经过考试培训的调查员对抽样人群进行面对面问卷调查和空腹血糖测定,空腹血糖值≥6.1 mmol/L者再进行餐后2 h血糖测定.描述该人群的T2DM患病率及其人群分布特征,分析患T2DM的危险因素.结果 天津市社区成年肥胖人群T2DM患病率为11.74%,女性患病率(13.90%)高于男性(8.75%).肥胖人群按不同人群特征分组后,不同年龄、文化程度、职业、地区和BMI之间T2DM患病率差异有统计学意义.经单因素和多因素的logistic回归分析,年龄(OR=1.383,95%CI:1.254～1.525)、性别(OR=1.591,95%CI:1.230～2.059)是成年肥胖人群患糖尿病的危险因素,食用水果(OR=0.867,95%CI:0.774～0.971)是保护因素.结论 肥胖人群的T2DM患病率较高,T2DM在不同肥胖人群特征的分布和影响因素与全人群有所不同,可能与肥胖者本身存在的危险因素有关.

Prevalence and risk factors of type 2 diabetes mellitus in adult obese population in Tianjin

Objective To investigate the type 2 diabetes mellitus(T2DM)prevalence and related risk factors in adult population with obesity in Tianjin. Methods With stratified cluster randomized sampling, 2888 obese people with BMI≥28 kg/m2, aged 18 years old and over were selected from three urban and three rural regions of Tianjin, in 2006. Information on risk factors was collected with questionnaire through face-to-face interview by trained workers and data on fasting blood glucose(FBG)was collected at the same time. 2hrPPG was tested among the people who' s FBG ≥6.1 mmol/L at the hospital. Prevalence of T2DM was calculated and the distribution of T2DM in the described subgroups and the risk factors analyzed with SPSS software. Results The prevalence of T2DM in adult population with obesity was 11.74%, with females(13.90%)higher than males (8.75%). The prevalence rates of T2DM were statistically different among different groups, classified by age, education, occupation, district and BMI. Results from the univariate and multivariate logistic regression analysis showed that the risk factors of T2DM were age(OR=1.383, 95% CI: 1.254-1 .525)and sex(OR= 1.591,95% CI: 1.230-2.059)while the protective factor was fruit intake(OR=0.867, 95% CI: 0.774-0.971). Conclusion The prevalence of T2DM in adult with obesity was considered to be high. The distribution of T2DM in different subgroups and affecting factors of T2DM in obese adults were different from general population.
