南京市城区老年人群2000年和2017年糖尿病自我报告患病率情况及变化

Prevalence and its change of self-reported diabetes mellitus in 2000 and 2017 among elderly people in urban area of Nanjing,China

目的了解南京市城区≥60岁老年人群2000年和2017年自我报告糖尿病患病率的分布特征及变化情况。方法利用南京市城区≥60岁老年人群2000年和2017年横断面调查的代表性数据进行分析,调查内容包含社会人口学信息、自我报告糖尿病等主要慢病患病情况、慢病相关的生活及行为方式和身高、体质量。采用χ^(2)检验比较不同年份调查对象的人口学分布特征、自我报告糖尿病的患病率及流行病学分布的差异。结果2000年和2017年南京市城区≥60岁老年人群自我报告糖尿病的总体患病率分别为6.1%(95%CI:0.055~0.067)和20.2%(95%CI:0.192~0.212),呈明显上升趋势(P<0.01)。两个年份之间性别、年龄、文化程度、吸烟、饮酒、BMI及体力活动情况中各特征人群的自报患病率差异均具有统计学意义(P<0.05)。每个年份不同年龄组间患病率差异均存在统计学意义(P<0.05),2000年不同文化程度及饮酒情况人群间患病率差异有统计学意义(P<0.05),2017年不同BMI及PA分组人群间患病率差异有统计学意义(P<0.05)。结论南京市城区老年人群糖尿病自报患病率在全国处于较高水平且呈上升趋势,应重点关注60~79岁、超重肥胖及体力活动不充足老年人群的糖尿病防控。

Objective To investigate the prevalence trend and risk factors of self-reported diabetes mellitus in the elderly people living in urban areas of Nanjing.Methods Two cross-sectional surveys were undertaken in the same urban areas of Nanjing,China,in 2000 and 2017.The same multi-stage sampling approach was used to randomly select participants.Demographic features and health-related behaviors were collected using questionnaires,and the height and weight were measured.Chi-square test was used to examine the demographic features,prevalence rate and epidemiological distribution of self-reported diabetes mellitus between the subjects in 2000 and those in 2017.Results The prevalence of self-reported diabetes mellitus in the elderly population of Nanjing was 6.1%(95%CI:0.055-0.067)in 2000 and 20.2%(95%CI:0.192-0.212)in 2017(P<0.05),respectively.There were statistically significant differences in the self-reported prevalence rate in the elderly with same gender,age,education level,smoking,drinking,BMI and physical activity(P<0.05)between the two groups.There was significant difference in the prevalence of self-reported diabetes mellitus between the elderly with different age in each group(P<0.05).In 2000,there were significant differences in the prevalence among the elderly with different levels of education and drinking(P<0.05).In 2017,there were significant differences in the prevalence among the elderly with different levels of BMI and physical activity(P<0.05).Conclusions The prevalence of self-reported diabetes mellitus is high in the elderly population in Nanjing,which shows a time-dependent trend of increase.
