Short-term exposure to PM has been associated with population excess death. This issue is of critical concern in China given its high level of exposure to PM compared to that of the rest of the world. Existing studies were conducted from 2013-2015 and have failed to capture the full effects of China's actions towards cleaner air in recent years, such as the first Action Plan for Air Pollution Prevention and Control issued in 2013. This study uses the longest time series data to date from 2013-2018, provides the latest evidence on PM and cause-specific death nationwide, and identifies regional patterns of PM-related effects as well as PM-related susceptible populations. This study suggests that the development of standards and the implementation of actions to clean the air and protect public health should be tailored to PM-related sensitive diseases, susceptible populations, and regional patterns.
短期接触细颗粒物（PM）已与人群超额死亡相关。鉴于中国与世界其他地区相比细颗粒物暴露水平较高，这一问题在中国备受关注。现有研究是在2013年至2015年期间开展的，未能充分体现中国近年来在改善空气质量方面所采取行动的全部成效，比如2013年发布的首个《大气污染防治行动计划》。本研究使用了迄今为止最长的时间序列数据（2013年至2018年），提供了关于全国范围内细颗粒物及特定病因死亡的最新证据，并确定了细颗粒物相关影响的区域模式以及与细颗粒物相关的易感人群。本研究表明，空气质量标准的制定以及清洁空气和保护公众健康行动的实施应针对与细颗粒物相关的敏感疾病、易感人群和区域模式进行调整。
