目的:了解老年人群所有原因及心血管疾病的死亡率。分析糖代谢异常对所有原因及心血管疾病死亡率的影响。方法:健康查体年龄60岁以上老年人群为基线人群。糖尿病(DM)诊断按照1985年WHO标准确定,各组累积生存率的估计采用Kaplan-Meier方法和Cox比例风险模型。结果:IGT和DM组心、脑血管疾病每1000人年的死亡率分别为7.55和8.86,明显高于NGT组2.43(P<0.05,P<0.01),经年龄调整IGT和DM组死亡的相对危险度(RR)为2.70(95%CI 1.56-3.81)和2.84(1.57-4.12),其它心血管疾病危险因素调整后的死亡RR为3.14(2.15-5.12)和3.46(2.20-5.23)。结论:老年人群DM和IGT患者.因心血管疾病导致的死亡率明显高于NGT,DM和IGT是导致心血管疾病死亡的重要危险因素。
Purpose: To understand all causes of the elderly and cardiovascular mortality. Analysis of abnormal glucose metabolism on all causes and cardiovascular mortality. Methods: The physical examination of the elderly over 60 years of age as the baseline population. Diabetes mellitus (DM) was diagnosed according to the WHO standard of 1985, and the cumulative survival rate of each group was estimated using Kaplan-Meier method and Cox proportional hazards model. Results: The death rates of heart and cerebrovascular diseases in IGT and DM group were 7.55 and 8.86 respectively, which were significantly higher than those in NGT group 2.43 (P <0.05, P <0.01) Risk adjusted RRs were 2.70 (95% CI 1.56-3.81) and 2.84 (1.57-4.12). Adjusted RRs for other cardiovascular risk factors were 3.14 (2.15-5.12) and 3.46 (2.20-5.23). Conclusion: The mortality of cardiovascular disease in DM and IGT elderly patients is significantly higher than that in NGT, and DM and IGT are the important risk factors of cardiovascular death.
