不适当的表面温度显著增加了对非意外,心血管和循环问题的紧急救护车 (EAC) 的呼叫. 老年人和男性等弱势群体最容易受到极端的高温和低温的影响.
科学领域:
- 环境健康 环境健康
- 公共卫生 公共卫生
- 流行病学 流行病学
背景情况:
- 不适当的表面温度 (AT) 构成全球健康风险,但其对紧急救护车呼叫 (EAC) 的影响还未得到充分研究.
- 了解与温度相关的健康负担对于公共卫生干预至关重要.
研究的目的:
- 调查表面温度与紧急救护车呼叫之间的关联.
- 量化归因于AT的EAC负担,并确定脆弱人群.
主要方法:
- 利用了2014-2019年每日EAC,气象和空气污染物数据.
- 应用分布式滞后非线性模型来评估AT效应和滞后影响.
- 根据疾病病因,性别和年龄进行了分层分析.
主要成果:
- 在AT和非偶然性,心血管和循环EAC之间发现了U形关系.
- 最低风险的最佳AT为22.54°C (非意外),17.12°C (心血管) 和12.74°C (循环).
- 男人和≥65岁的个体对热和寒都表现出更高的敏感性;女性对热更容易受到伤害. 非偶然性,心血管和呼吸系统EAC的可归因分数分别为6.88%,10.37%和4.94%.
结论:
- 表面温度显著影响EAC,中度变化比极端条件有更大的影响.
- 公共卫生战略应包括热极端和温度调节设施的早期预警系统.
- 需要有针对性的干预措施来保护弱势群体,特别是老年人,免受温度相关的健康风险.
