目的探讨老年人静息心率过快与糖尿病发病的关系。方法对苏州市相城区60岁以上老年人进行健康体检,抽取没有糖尿病家族史、空腹血糖正常的1 874例老年人作为研究对象,连续跟踪调查2年,每年按照临床标准检测血糖等指标,1年后确诊为糖尿病不再追踪,非糖尿病老年人继续跟踪调查1年,2年后再次体检相关指标。应用SPSS 19.0软件进行单因素分析,多因素非条件Logistic回归分析糖尿病发病与静息心率的关系。结果单因素研究中,不同静息心率组、血压组及体质指数组2年后糖尿病发病率差异有统计学意义。调整可能的混杂因素后的非条件Logistic回归显示,静息心率过快老年人2年后糖尿病发病风险为静息心率正常人的1.815倍,P<0.01,差异有统计学意义。结论降低老年人静息心率过快的患病率,或可以减少老年人糖尿病的发病风险。
Objective To investigate the relationship between resting heart rate and diabetes in the elderly. Methods A total of 1 874 elderly people without family history of diabetes and normal fasting plasma glucose were selected as the research objects for the elderly over 60 years old in Xiangcheng District of Suzhou City. The follow-up survey was conducted for 2 years and the blood glucose and other indexes were tested every year according to clinical criteria. Years later diagnosed with diabetes is no longer tracked, non-diabetic elderly continue to track the survey for 1 year, 2 years after the physical examination-related indicators. Univariate analysis using SPSS 19.0 software, multivariate non-conditional Logistic regression analysis of the relationship between diabetes and resting heart rate. Results In the univariate study, the differences in incidence of diabetes between two groups of different resting heart rate group, blood pressure group and body mass index group were statistically significant. Non-conditional logistic regression after adjustment for possible confounders showed that resting heart rate was significantly higher in elderly people at 2 years after the onset of diabetes mellitus was 1.815 times normal resting heart rate (P <0.01), the difference was statistically significant. Conclusion Reducing the prevalence of resting heart rate in the elderly may reduce the risk of diabetes in the elderly.
