重庆工业污染区1991～1998年居民死因及潜在减寿年数分析

目的 分析20世纪90年代重庆市工业污染区居民主要死因。方法 应用死亡率、死因顺位、潜在减寿年数（YPLL）及潜在价值减寿年数（VYPLL）等指标分析该区1991～1998年死因资料。对照组为该市非工业污染文化社区。结果 该区平均粗死亡率为7.34‰（标化死亡率4.61‰）。主要死因顺位为：恶性肿瘤、脑血管病、呼吸系病、心脏病和意外死亡。恶性肿瘤死率为198.07/10万（标化死亡率126.35/10万），其中肺癌居第一位，死亡率为65.49/10万（标化死亡率45.27/10万）。主要死因标化潜在减寿率（SYPLL率）和标化潜在价值减寿率（SVYPLL率）顺位的第一位都为意外死亡。结论 为了降低该居民死亡率，既要进一步加强其自然环的治理，也应重视社会环境的治理。

Analysis of causes of death and YPLL on residents in the industrial pollution area in Chongqing from 1991 to 1998

OBJECTIVE: To investigate the causes of death in residents living in the area of industrial pollution in Chongqing. METHODS: Mortality rate, sequence of causes of death, years of potential life lost (YPLL) and the valued years of potential life lost (VYPLL) were used to analyze causes of death in 1991 - 1998. Community not polluted by industry was chosen to serve as control. RESULTS: The annual average mortality rate of the residents was 7.34 per thousand (standard mortality rate 4.61 per thousand). The sequence of major causes of death was shown as below: malignant tumors (mortality rate 198.07/10(5), standard mortality rate 126.35/10(5)), cerebrovascular diseases (mortality rate 159.13/10(5), standard mortality rate 92.66/10(5)), respiratory system diseases (mortality rate 107.33/10(5), standard mortality rate 84.85/10(5)), cardiac diseases (mortality rate 95.36/10(5), standard mortality rate 59.37/10(5)) and accidental deaths (mortality rate 47.08/10(5), standard mortality rate 43.28/10(5)). Among malignant tumors, lung cancer took the lead with a mortality rate of 65.49/10(5) (standard mortality rate 45.27/10(5)). In both sequences of standard rates of YPLL and VYPLL for major causes of deaths, accidental death was always took the first place. CONCLUSION: In order to reduce mortality rate of the residents in the area, it is necessary to strengthen the administration of natural and social environment of the area.
