中国冠心病患者健康生命年损失研究

Study on loss of healthy life years of patients with coronary heart disease

目的计算冠心病的健康生命年损失,确定中国冠心病的高危人群和高危地区,为冠心病的防治工作重点提供科学依据。方法将2005年中国冠心病的死亡情况按照地区、年龄、性别整理,利用残疾调整生命年(DALY)指标计算冠心病的健康生命年损失。结果中国冠心病健康生命年损失为139953.2537人年(3.72人年/千人),其中以死亡损失的健康生命年为130753.9479人年,残疾损失的健康生命年为9199.2788人年;70～80岁为健康生命年损失最高的年龄段,男性高于女性,城市高于农村。结论冠心病的健康生命年损失主要由死亡引起,男性和城市居民冠心病的健康生命年损失更应引起重视。

Objective By calculating healthy life years caused by coronary heart disease in China to identify population and region at high risk, and to provide a scientific basis for the prevention of the disease. Methods Data on the mortality of coronary heart disease all over the country were sorted according to region, age and gender. Then disability adjusted life years （DALY） index was used to calculate the loss of healthy life years. Results The research showed that DALYs of coronary heart disease in China were 139 953. 9479 person year （3.72/1 000 person year）. Years of life lost due to premature death （YLLs） were 130 753.95 person year and years lived with disability（YLDs） were 9 199.2788 person year, which mostly concentrated at the ages group of 70--80. The DALY of the male was higher than that of the female, and the DALY of the urban patients was higher than that of the rural. Conclusion The loss of healthy life years of coronary heart disease was mainly caused by death. More attention should be paid to male and urban residents.
