空气污染,特别是颗粒物 (PM) 和二氧化 (NO2),与婴儿因支气管炎住院治疗的增加有关. 短期暴露于PM10显示出统计学上显著的风险增加,突出显示空气质量.
科学领域:
- 环境健康 环境健康
- 儿科呼吸系统医学 儿科呼吸系统医学
- 流行病学 流行病学
背景情况:
- 支气管炎是婴儿住院的主要原因,已知危险因素包括早产和烟雾暴露.
- 新出现的证据表明,空气污染可能导致婴儿呼吸系统疾病,但其在支气管炎住院治疗中的作用仍在争论中.
研究的目的:
- 系统地审查和元分析空气污染物暴露与婴儿支气管炎住院之间的关联.
- 评估各种空气污染物暴露的婴儿因支气管炎住院的风险.
主要方法:
- 按照PRISMA指南进行系统审查和元分析,搜索PubMed,Embase和Web of Science,直到2024年5月.
- 包括的研究检查了空气污染物和支气管炎在婴儿住院的情况,年龄在两岁以下.
- 分析估计了污染物水平和住院风险之间的关联.
主要成果:
- 在788项已识别的研究中,23项研究符合纳入标准.
- 在暴露于颗粒物 (PM2.5,PM10) 和二氧化 (NO2) 和增加住院风险之间发现了积极的关联.
- 分析表明,PM2.5,PM10和NO2的住院风险增加了2%-9%,只有短期的PM10暴露才具有统计意义.
结论:
- 颗粒物 (PM2.5,PM10) 和二氧化 (NO2) 可能是婴儿支气管炎住院的危险因素.
- 需要进一步的标准化研究来澄清其他空气污染物的作用,如二氧化硫,一氧化碳,臭氧和黑碳.
