2015-2020年内蒙古自治区学生肺结核疫情变化趋势及特征分析

Incidence trend and epidemiological characteristics of pulmonary tuberculosis in students in Inner Mongolia, 2015–2020

  • 摘要:
      目的  分析内蒙古自治区(内蒙古)学生肺结核疫情变化及特征,为有效控制学生肺结核疫情提供依据。
      方法  收集2015—2020年《传染病监测管理》中“传染病监测系统”的“法定传染病监测”和“结核病管理信息”两个模块和《内蒙古统计年鉴》中有关学生肺结核疫情和人口的数据,分析学生肺结核报告发病三间分布和就诊延迟的情况。
      结果  2020年内蒙古共报告学生肺结核患者405例,学生肺结核报告发病率为13.76 /10万(405/308.77万)。与2015年(15.86/10万,493/310.91万)相比较下降了13.20%。 每年3、4月为学生肺结核报告发病率高峰;2020年中部报告发病率较低(4.54/10万),东部(24.87/10万)和西部(9.82/10万)较高。 2020年各年龄组报告发病数构成比中,高中阶段(16~18岁)占比最高,为39.05%(157/402),其次是大学本专本科阶段(19~22岁),为32.84%(132/402)。 2020年学生肺结核患者中,就诊延迟患者226例,就诊延迟率为56.22%(226/402)。
      结论   学生肺结核报告发病率总体呈不规律波动,东部地区发病率偏高,16~18岁为高发年龄段,是结核病防控的重点人群,提高主动监测能力,防止学校疫情蔓延。

     

    Abstract:
      Objective  To analyze the incidence trend and epidemiological characteristics of pulmonary tuberculosis (TB) in students in Inner Mongolia Autonomous Region and provide a reference for the effective prevention and control of pulmonary TB in students.
      Methods  The pulmonary TB reporting data in students in Inner Mongolia from 2015 to 2020 were collected from the subsystems of “Infectious Disease Surveillance” and “Tuberculosis Information Management” in Infectious Disease Surveillance and Management System and the population data were collected form Inner Mongolia Statistical Yearbook for the analyses on the spatial, temporal and population distributions of reported pulmonary TB cases in students and the treatment delay of the cases.
      Results  A total of 405 pulmonary TB cases in students were reported in Inner Mongolia in 2020 with the reported incidence of 13.76/100 000 (405/3 087 700), a decrease of 13.20% compared with 2015 (15.86/100 000, 493/3 109 100). The annual reported incidence peak of pulmonary TB in students was during March–April. The reported incidence during the two months was lower in central area (4.54/100 000) than in eastern area (24.87/100 000) and western area (9.82/100 000). In terms of the constituent ratio of the pulmonary TB cases in all age groups in 2020, the proportion was highest (39.05%, 157/402) in age group 16–18 years (senior high school students), followed by that (32.84%, 132/402) in age group 19–22 years (college students). The delayed treatment rate of the pulmonary TB cases was 56.22% (226/402).
      Conclusion  The reported incidence of pulmonary TB in students in Inner Mongolia fluctuated irregularly. The cases mainly occurred in age group 16–18 years, and the incidence was slightly higher in eastern area. Therefore, it is necessary to further strengthen the health education and active TB surveillance in schools to prevent the spread of pulmonary TB.
