目的:对老年人群冠心病(CHD)患病率、发病率及其相关危险因素进行分析研究。方法;健康查体年龄60岁以上的无CHD的老年人群作为基线入群,计算基线时CHD患病率,采用入年法计算其发病率。同时还采用Logistic回归分析对4年中新发的CHD危险因素进行分析。结果:老年人群CHD的发病率为34.26/1000人年,其中IGT和DM组分别为50.42和57.08/1000人年,明显高于NGT组的27.55/1000人年(P<0.05,<0 01)。经Logistic逐步回归分析表明,DM、IGT、高血压(HT)、BMI和年龄与CHD发生明显相关。结论:IGT和DM组的CHD患病率和发病串明显高于NGT组,糖代谢异常、高血压、肥胖和增龄与CHD发病密切相关。
Objective: To analyze the prevalence, incidence and related risk factors of coronary heart disease (CHD) in the elderly population. Methods: The CHD-free elderly people over 60 years of age were enrolled in the study. The prevalence of CHD at baseline was calculated and the incidence of CHD was calculated by the year-old method. Logistic regression analysis was also used to analyze the risk factors for new-onset CHD in 4 years. Results: The incidence of CHD in the elderly population was 34.26 / 1000 person-years. The IGT and DM groups were 50.42 and 57.08 / 1000 person-years respectively, significantly higher than 27.55 / 1000 person-years in the NGT group (P <0.05 and <0.01) . Logistic stepwise regression analysis showed that DM, IGT, high blood pressure (HT), BMI and age were significantly associated with CHD. Conclusion: The prevalence and incidence of CHD in IGT and DM groups were significantly higher than that in NGT group. The abnormal glucose metabolism, hypertension, obesity and aging were closely related to the incidence of CHD.
