目的了解天津市某社区50岁~居民糖尿病的患病情况及其影响因素,为进行有效防治提供参考依据。方法采用现况调查方法,对天津市某社区50岁~居民共3 572人进行问卷调查、体格检查和血糖检测,采用Logistic回归分析糖尿病的相关因素。结果调查人群糖尿病患病率为17.6%,男、女性患病率分别为16.8%和18.3%,差异无统计学意义(χ2=1.346,P>0.05)。不同年龄组之间糖尿病患病率不同(χ2=20.811,P<0.01),随着年龄的增长,糖尿病患病率呈增高趋势,70岁~人群患病率达20.2%。多因素非条件Logistic回归分析结果显示,年龄、体质指数、腰围、糖尿病家族史和高血压与糖尿病发生有关。结论天津地区调查人群糖尿病患病率处于全国较高水平,应重视加强综合防治。 Objective To understand the prevalence of diabetes and its influencing factors among 50-year-old residents of a community in Tianjin and provide reference for effective prevention and treatment. Methods A questionnaire survey, physical examination and blood sugar test were conducted among 3 572 residents aged 50 to residents in a community in Tianjin using Logistic regression. Logistic regression was used to analyze the related factors of diabetes. Results The prevalence of diabetes was 17.6% in the surveyed population. The prevalence rates of male and female were 16.8% and 18.3% respectively, with no significant difference (χ2 = 1.346, P> 0.05). The prevalence of diabetes among different age groups was different (χ2 = 20.811, P <0.01). With the increase of age, the prevalence of diabetes increased and the prevalence of diabetes was 70.2% to 20.2%. Multivariate non-conditional logistic regression analysis showed that age, body mass index, waist circumference, family history of diabetes and hypertension were associated with diabetes. Conclusion The prevalence of diabetes in the surveyed population in Tianjin is at a high level throughout the country and emphasis should be placed on strengthening comprehensive prevention and treatment.
