1990～2016年云南省宣威市肺癌死亡流行特征分析

Epidemiological Features of Lung Cancer Mortality between 1990 and 2016 in Xuanwei City,Yunnan Province

目的描述1990~2016年云南省宣威市肺癌死亡流行趋势,为宣威肺癌防控提供科学依据。方法数据来源包括1990~1992年及2004~2005年宣威市死因回顾调查数据、2011~2013年及2014~2016年宣威市死因监测数据,其中,针对不同时期的死因监测数据进行了相应的漏报校正,并计算以上4个时期不同特征肺癌粗死亡率、标化死亡率及其95%CI。结果1990~1992年、2004~2005年、2011~2013年和2014~2016年宣威市肺癌粗死亡率分别为34.0/10万、89.8/10万、102.3/10万和87.2/10万。自2004年起,宣威市肺癌标化死亡率呈现下降趋势,但仍然维持在较高水平;各年龄组肺癌死亡率也大多呈现递减趋势,自2014年起40岁以下年龄组开始下降且有统计学意义;高发区除龙场外,其余各乡镇肺癌标化死亡率均呈现下降趋势。结论宣威市肺癌死亡虽然仍维持在较高水平,但自2004年以后肺癌标化死亡率已经呈现出逐步降低趋势。自2014年以后,40岁以下人群肺癌死亡率下降具有统计学意义。

Objective To describe the trend of lung cancer mortality in Xuanwei City,Yunnan Province,from 1990 to 2016 and provide scientific evidence for the prevention and control of lung cancer in Xuanwei. Methods Mortality data from the 2nd(year 1990- 1992)and 3rd(year 2004- 2005)Retrospective Survey on Causes of Death,and the Routine Death Registration System(year 2011- 2013 and 2014- 2016)in Xuanwei were used in this study.We calibrated the missing report of the mortality data for the corresponding periods,calculated the crude mortality rates,standardized mortality rates and corresponding 95% CI of different types of lung cancers in the above four periods. Results The crude mortality rates of all lung cancers in Xuanwei for these four periods(1990- 1992,2004- 2005,2011- 2013,and 2014- 2016)were 34.0/100 000,89.8/100 000,102.3/100 000 and 87.2/100 000 respectively.The standardized morality rate of lung cancer remain high in Xuanwei although it has been decreasing since 2004.Morality rates of lung cancer for most age groups showed decreasing trends.The decrease has been statistically significant in the ≤ 40 year group since 2014.Except for Longchang,the standardized mortality rates have decreased in all other townships with high lung cancer prevalence. Conclusions Although the mortality rate of lung cancer remains high in Xuanwei,it has shown a decreasing trend since 2004.The decrease in lung cancer mortality in populations younger than 40 years is statistically significant.
