这项研究引入了一种中风热风险模型,以预测与热有关的中风死亡. 该模型提供了有针对性的干预措施,大大改善了可避免的因热而导致的过度死亡的识别.
科学领域:
- 环境健康 环境健康
- 流行病学 流行病学
- 公共卫生 公共卫生
背景情况:
- 暴露于热量是已知的中风风险因素.
- 目前针对与热相关的中风的干预措施并没有准确的目标.
- 气候变化需要改善预防与热有关的疾病的战略.
研究的目的:
- 开发和验证中风热风险分级预测模型.
- 为了实现精确的干预,以减轻与热有关的中风风险.
- 将模型的有效性与现有预警系统进行比较.
主要方法:
- 使用时间序列方法分析气象和中风死亡率数据 (2013-2018).
- 基于非线性温度-死亡率关系的四级风险分级系统的开发.
- 使用案例交叉和时间序列分析 (2019-2022) 的验证,考虑人口和地理因素.
主要成果:
- 该模型确定了一种非线性温度与死亡率的关系.
- 在最高风险水平,中风死亡率增加了13.8% (一般人群) 和16.4% (老年人群).
- 开发的模型在预测中风死亡率方面明显优于中国气象局的预警系统.
结论:
- 脑卒中热风险分级预测模型是用于精确干预的经过验证的数字工具.
- 以该模型为指导的干预措施几乎可以将可避免的可归因于热量的过度死亡比例增加一倍.
- 这种模型可以帮助减轻与热有关的中风风险,特别是在不断变化的气候条件下.
