          Objective To understand the epidemiological characteristics of pulmonary tuberculosis(PTB) in the poor counties of Chongqing from 2011 to 2018, and we provide a basis for improve the control strategy of PTB in poor counties.

          Methods Data 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.

          Results The annual reported incidence of tuberculosis in 14 poor districts and counties in Chongqing was 110.9/100 000 in 2011, and 103.7/100 000 in 2018, respectively.The average annual reported incidence of PTB was 106.5/100 000 from 2011 to 2018, showed a slow downward trend by year. The average annual decline rate was 1.0%. The reported incidence of PTB in poor counties was significantly higher than that in non-poor counties (χ 2=9 705.197, P<0.05). The top three regions were Pengshui county (167.9/ 100 000), Qianjiang district (163.4/100 000) and Chengkou county (156.3/100 000). The reported incidence in male (199.4/100 000) was higher than in female (52.6/100 000). 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.

          Conclusion The epidemic situation of PTB in poor districts and counties of Chongqing has fallen slowly. Preventive and control measures should be strengthened in poor areas.


          摘要: 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=9 705.197, 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。
