身体活动 (PA) 与更好的健康结果有关. 虽然空气污染可能会增加人们对运动的好处, 但它并不能否定运动对整体健康的重要性.
科学领域:
- 环境健康
- 公共卫生
- 流行病学
背景情况:
- 已知体力活动可以降低慢性疾病的风险.
- 新出现的证据表明空气污染可能会影响PA的健康益处.
- 这项研究调查了空气污染是否会改变PA与主要健康结果之间的关联.
研究的目的:
- 确定空气污染水平是否会改变身体活动对死亡的保护作用.
- 检查空气污染与癌症,主要心血管不良事件 (MACE),2型糖尿病和慢性阻塞性肺病 (COPD) 的相互作用.
主要方法:
- 使用了来自414644名参与者的英国生物库数据 (2006-2022年).
- 通过自我报告 (IPAQ) 和加速度计来评估身体活动.
- 使用土地利用回归模型测量空气污染物 (PM2.5,PM10,NO) 并使用Cox比例危险模型分析与健康结果的关联.
主要成果:
- 低血压与所有研究的健康结果的风险增加有关.
- 较高的PM2.5度与死亡,MACE,糖尿病和COPD的风险增加有关,但与癌症无关.
- 自我报告的PA与死亡率和癌症的保护性关联在空气污染较高的地区得到了放大,这表明了显著的相互作用.
结论:
- 在英国,空气污染并没有削弱体力活动对健康的重要影响.
- 这些发现支持不论环境空气污染程度如何,继续促进体力活动.
- 互动表明,自我报告的体力活动的好处可能在受污染的环境中更为明显.
