改善中国城市空气质量带来了显著的健康效益, 达到世界卫生组织的空气质量标准每年可以挽救超过180万人的生命.
科学领域:
- 环境健康
- 心血管疾病流行病学
- 公共卫生政策
背景情况:
- 在中国,户外空气污染是可预防的重大健康问题.
- 这项研究探讨了改善中国城市空气质量的潜在健康益处.
研究的目的:
- 预测在中国城市实现不同空气质量标准的健康效益.
- 将这些收益与传统心血管风险因素控制的收益进行比较.
主要方法:
- 利用心血管疾病政策模型-中国对2017年至2030年的预测.
- 由冠心病,中风以及其他原因造成的死亡.
- 在三个PM2.5减少场景下获得的预期寿命.
主要成果:
- 如果将PM2.5降低到北京奥运会水平,
- 达到中国二级或世卫组织标准可以分别达到992,000或1827,000年的寿命.
- 这些好处超过了世卫组织高血压和吸烟控制目标的好处.
结论:
- 中国的空气质量改善带来了不同的健康益处.
- 达到世卫组织的空气质量标准可以获得相当长的寿命,相当于或超过主要的公共卫生干预措施.

Physical activity, whether through structured exercise or casual activities like walking, biking, or dancing, is a cornerstone of a...
Physiological Control of Respiration
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...
