This study assessed the long-term health impact of environmental exposures associated with open pit burning in deployed US service members.
Two hundred individuals deployed to Balad, Iraq, and Bagram, Afghanistan, with known exposure to open pits, were matched to 200 non-deployed service members. Both cohorts were observed for adverse health outcomes after returning from deployment.
Slight increased risks were observed for respiratory diseases in the Bagram cohort (adj RR: 1.259), and for cardiovascular disease in the Balad cohort (adj RR: 1.072), but the findings were not significant. The combined deployed cohort showed lower risks for adverse health outcomes, suggesting a healthy deployer effect.
In conclusion, this study did not find significantly increased risks for selected health outcomes after burn pit exposure during deployment among two deployed cohorts compared with a non-deployed cohort.
本研究评估了美国现役军人露天焚烧相关环境暴露对长期健康的影响。
将200名已知暴露于露天焚烧环境的部署到伊拉克巴拉德和阿富汗巴格拉姆的军人，与200名未部署的军人进行匹配。两组队列在部署返回后均观察不良健康结局。
在巴格拉姆队列中观察到呼吸系统疾病风险略有增加（校正风险比：1.259），在巴拉德队列中观察到心血管疾病风险略有增加（校正风险比：1.072），但结果不显著。综合部署队列显示不良健康结局风险较低，提示存在健康部署者效应。
总之，与未部署队列相比，本研究未发现两个部署队列在部署期间暴露于燃烧坑后特定健康结局风险显著增加。
