重庆市2011-2018年贫困区县肺结核流行特征

Epidemiological characteristics of pulmonary tuberculosis in poor districts and counties of Chongqing,2011-2018

目的了解重庆市贫困区县肺结核疫情的流行特征,为完善贫困区县肺结核防控策略提供依据。方法从传染病报告信息管理系统导出2011-2018年贫困区县的肺结核报告卡信息,采用描述性流行病学方法分析贫困区县的肺结核三间分布特征。结果2011年和2018年重庆市14个贫困区县肺结核年报告发病率分别为110.9/10万和103.7/10万。2011-2018年贫困区县肺结核年均报告发病率为106.5/10万,呈缓慢下降趋势,年平均递降率为1.0%。贫困区县的肺结核年平均报告发病率显著高于非贫困区县(χ^2=9705.197,P<0.05),年平均报告发病率排名前三位的分别是彭水县(167.9/10万)、黔江区(163.4/10万)和城口县(156.3/10万)。男性(199.4/10万)高于女性(52.6/10万),报告病例数最多的年龄组为15~29岁组,占病例总数26.6%。农民发病例数最多,占65.2%。结论重庆市贫困区县肺结核疫情下降缓慢,需进一步加强贫困地区结核病防治工作,完善防控策略,有效控制疫情。。

Objective To understand the epidemiological characteristics of pulmonary tuberculosis(PTB)in the poorcounties of Chongqing from 2011 to 2018,and we provide a basis for improve the control strategy of PTB in poor counties.MethodsData of the PTB cases reported from the China Infectious Disease Surveillance System were collected.Descriptive epidemiological method was used to analyze the distribution characteristics of PTB form 2011 to 2018.ResultsThe annualreported incidence of tuberculosis in 14 poor districts and counties in Chongqing was 110.9/100000 in 2011,and 103.7/100000 in 2018,respectively.The average annual reported incidence of PTB was 106.5/100000 from 2011 to 2018,showed a slowdownward trend by year.The average annual decline rate was 1.0%.The reported incidence of PTB in poor counties wassignificantly higher than that in non-poor counties(χ^2=9705.197,P<0.05).The top three regions were Pengshui county(167.9/100000),Qianjiang district(163.4/100000)and Chengkou county(156.3/100000).The reported incidence in male(199.4/100000)was higher than in female(52.6/100000).The largest number of reported cases were concentrated in the 15-29 age group,accounting for 26.6%of the total.The number of PTB in farmers has become the highest among all occupations,accounting for 65.2%of the total percentage.ConclusionThe epidemic situation of PTB in poor districts and counties of Chongqing hasfallen slowly.Preventive and control measures should be strengthened in poor areas.
