目的了解四川省居民1989-2011年间死亡率水平、变化趋势及根本死因。方法利用四川省1989-2011年死亡监测资料,采用死亡率、期望寿命、YPLL等指标,对四川省死亡变化趋势及根本死因进行分析。结果四川省粗死亡率由1989年的656.96/10万下降到2011年的624.58/10万。农村高于城市,男性高于女性。期望寿命由68.85岁增加到75.64岁。全死因YPLL从1989年的1 111 467人年逐步下降到2011年的715 967人年。全死因YPLL率从1989年的111.90‰下降到2011年的58.94‰。前3位死因顺位由呼吸系统疾病、循环系统疾病和肿瘤,转变为循环系统疾病、肿瘤和呼吸系统疾病。前3位根本死因占总死因的比例由74.09%升高到82.53%。结论四川省居民死亡率逐步降低,期望寿命有所升高,循环系统疾病为四川省居民的第1位死因,慢性病对居民健康的影响越来越严重。
Objective To understand the level of mortality, the changing trend and the basic cause of death among residents in Sichuan province from 1989 to 2011. Methods According to the data of death monitoring in Sichuan Province from 1989 to 2011, mortality, life expectancy, YPLL and other indicators were used to analyze the trend of death and the underlying causes of death in Sichuan Province. Results The crude death rate in Sichuan dropped from 656.96 / 100,000 in 1989 to 624.58 / 100,000 in 2011. Rural is higher than city, and men are higher than women. Life expectancy increased from 68.85 to 75.64. The total cause of death YPLL gradually declined from 1,111,467 person-years in 1989 to 7,159,667 in 2011. The YPLL rate for all causes decreased from 111.90 ‰ in 1989 to 58.94 ‰ in 2011. The top three causes of death from respiratory diseases, circulatory diseases and tumors, into circulatory diseases, cancer and respiratory diseases. The proportions of the top three causes of death attributable to total death increased from 74.09% to 82.53%. Conclusions The mortality rate of residents in Sichuan Province has gradually decreased and their life expectancy has risen. The causes of circulatory diseases are the first cause of death among residents in Sichuan Province. The impact of chronic diseases on residents’ health is more and more serious.
