摘要:

目的: 探讨主要大气气态污染物对农村地区处于结核分枝杆菌潜伏感染(latent tuberculosis infection,LTBI)状态的成年人群肺结核发病的影响。方法: 本研究基于2013—2018年在农村地区开展的一项多中心、前瞻性结核分枝杆菌潜伏感染队列(LATENTTB-NSTM),对3866例基线LTBI者季度随访5年,收集新发活动性肺结核病例,根据居住地点和时间匹配气态污染物浓度,利用含时依协变量的Cox比例风险模型分别估计二氧化硫(SO2)、二氧化氮(NO2)、臭氧(O3)和一氧化碳(CO)与研究人群及不同年龄段、性别、受教育程度、家庭收入和生活方式等亚组新发活动性肺结核发病风险之间的关联。结果: 3866例LTBI者,随访中发现新发活动性肺结核58例。6个月的SO2和CO暴露水平分别每增加10μg/m3和100μg/m3,活动性肺结核发病风险分别增加81.0%(HR=1.810,95%CI:1.153~2.843)和19.6%(HR=1.196,95%CI:1.031~1.388)。SO2和CO暴露与活动性肺结核发病风险间的关联在老年人群和吸烟人群中更强,但差异均无统计学意义(交互作用P值均>0.05)。结论: 大气气态污染物尤其是SO2和CO暴露可引起农村地区LTBI者活动性肺结核发病风险升高,大气气态污染的治理对肺结核的控制具有不可忽视的意义。

Abstract:

Objective: To investigate the influence of primary atmospheric gaseous pollutants on the incidence of active pulmonary tuberculosis among adults in rural areas with latent tuberculosis infection (LTBI). Methods: This study utilized a multicenter, longitudinal cohort of rural residents with LTBI (LATENTTB-NSTM), spanning from 2013 to 2018, comprising 3866 participants who were monitored quarterly over five years to document new cases of active pulmonary tuberculosis. Concentrations of atmospheric gaseous pollutants such as sulfur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3), and carbon monoxide (CO) were precisely matched to the residential locations and periods under review. The association between exposure levels and the emergence of active tuberculosis was analyzed using time-dependent Cox proportional hazards models, stratified by age, sex, educational attainment, family income, and lifestyle factors. Results: Among 3866 individuals diagnosed with latent tuberculosis infection, surveillance identified 58 new cases of active pulmonary tuberculosis. Incremental exposures to SO2 and CO by 10 μg/m3 and 100 μg/m3, respectively, over a six-month period were associated with a respective 81.0% (HR=1.810, 95%CI: 1.153-2.843) and 19.6% (HR=1.196, 95%CI: 1.031-1.388) increase in the risk of developing active tuberculosis. Notably, these associations appeared more pronounced among older adults and smokers, though the differences did not reach statistical significance (interaction P-values >0.05). Conclusion: Exposure to atmospheric gaseous pollutants, particularly SO2 and CO, is associated with a heightened risk of developing active pulmonary tuberculosis among individuals with LTBI in rural settings. The management of air quality, therefore, plays a crucial role in the strategic control of tuberculosis.
