目的调查2004-2008年甘肃某矿区周围居民死因,为该矿区对周围居民健康影像评价提供相应的基础资料。方法采用回顾性流行病学调查方法,以甘肃某矿区为中心的30km半径范围内常住居民为调查组,以距该矿区90km处的一个乡镇所有居民为对照组,调查分析2004~2008年甘肃某矿区周围居民死因。结果调查组粗死亡率为334.43/10万,标化死亡率为380.21/10万,对照组粗死亡率为328.09/10万,标化死亡率为276.31/10万,差异无统计学意义(P>0.05);调查组男性死亡率明显高于女性,差异有显著性(P<0.05)。结论甘肃某矿区未对周围居民健康状况造成不利影响。
Objective To investigate the cause of death of residents around a mining area in Gansu from 2004 to 2008 and provide corresponding basic data for the health evaluation of surrounding residents in this mining area. Methods A retrospective epidemiological investigation was conducted in this study. The resident population within a radius of 30km centered on a mining area in Gansu Province was selected as the investigation group. The survey was conducted with a resident from a township of 90km away from the mining area. Residents around the mine cause of death. Results The crude death rate was 334.43 / 100 000 in the investigation group, the normalized mortality rate was 380.21 / 100 000, the crude mortality rate was 328.09 / 100 000 in the control group and the standardized mortality rate was 276.31 / 100 000, with no significant difference (P > 0.05). The male mortality in the survey group was significantly higher than that in the female group (P <0.05). Conclusion A mining area in Gansu Province has not adversely affected the health status of surrounding residents.
