生活在更绿色的地区与患有异常性肺纤维化 (IPF) 的风险较低有关. 这项研究强调了住宅绿色对IPF发病率的保护作用,特别是在遗传敏感个体中.
科学领域:
- 环境流行病学环境流行病学
- 肺部医学 肺部医学
- 公共卫生 公共卫生
背景情况:
- 住宅绿化与异常性肺纤维化 (IPF) 的发展之间的关系在很大程度上仍未被探索.
- 了解这种关联可以为预防呼吸道疾病的公共卫生策略提供信息.
研究的目的:
- 调查住宅绿化与事件IPF之间的关联.
- 识别潜在的中介途径,如空气污染.
- 为了检查这种关联是否在IPF的遗传风险亚组之间存在差异.
主要方法:
- 利用英国生物库数据,对469348名参与者进行了跟踪,直到2020年12月.
- 在各种缓冲距离 (300米至1500米) 上使用规范差异植被指数 (NDVI) 评估住宅绿色.
- 采用考克斯模型和因果调解分析,结合基因风险分层的多基因风险评分 (PRS).
主要成果:
- 在所有NDVI缓冲大小中,在住宅绿化和事件IPF之间观察到显著的反向关联.
- 更高的住宅绿色与IPF风险降低有关,危险比率从0.89到0.93.9不等.
- 在具有中等或高基因易感性IPF的个体中,保护作用更为明显.
- 确定PM2.5和NO2是显著的媒介,解释了绿色和IPF相关的很大一部分.
结论:
- 住宅绿色与患异常性肺纤维化风险降低有关.
- 像空气质量这样的环境因素在调解绿色空间的好处与IPF风险方面发挥着作用.
- 这些发现强调了城市绿化对呼吸系统健康的重要性.
