In this cross-sectional study, the authors examined the relationship between traffic-based air pollution and chronic, nonspecific respiratory symptoms among traffic policemen in Bangkok, Thailand. A total of 1,603 policemen who lived and worked in areas that had 3 different levels of airborne particulates were evaluated. The authors used a modified standardized questionnaire to identify nonspecific respiratory disease (NSRD) in participants. The prevalence of NSRD in heavily polluted, moderately polluted, and suburban areas was 13.0%, 10.9%, and 9.4%, respectively. Among nonsmokers, the age-adjusted prevalence of NSRD in the heavily polluted areas was significantly higher than in the suburban control area. Also among nonsmokers, the odds ratio for NSRD for each 10-microg/m3 increase in ambient particulate matter was 1.11. The authors concluded that the increased prevalence of respiratory symptoms among traffic policemen in Bangkok was associated with urban traffic air pollution.
在这项横断面研究中，作者调查了泰国曼谷交警中基于交通的空气污染与慢性非特异性呼吸道症状之间的关系。对总共1603名在具有3种不同空气颗粒物水平地区生活和工作的交警进行了评估。作者使用一份经过修改的标准化问卷来确定参与者中的非特异性呼吸道疾病（NSRD）。在重度污染区、中度污染区和郊区，NSRD的患病率分别为13.0%、10.9%和9.4%。在不吸烟者中，重度污染区经年龄调整后的NSRD患病率显著高于郊区对照区。同样在不吸烟者中，环境颗粒物每增加10微克/立方米，NSRD的比值比为1.11。作者得出结论，曼谷交警呼吸道症状患病率的增加与城市交通空气污染有关。
