Prevention & lipidsCohort study
Cardiovascular disease averted by China’s Clean Air Act and the potential benefit of further air pollution intervention: evidence based on the parametric G-computation
- Prospective cohort study with parametric G-computation simulation
- Parametric G-formula
Authors' conclusion
Existing air pollutant intervention policies have achieved considerable public health benefits in reducing CVD risk, and there is still significant room for improvement.
Study context
- Population
- China Multi-Ethnic Cohort; exposures PM2.5 and O3
- Exposure
- China's Clean Air Act (CCAA) and stricter air-pollution interventions vs no CCAA implementation
- Outcome
- CVD cases averted per 100 000 people and relative risk
Main finding
As reported in the abstract
CVD cases averted per 100 000 people
| Group | Value | WHO AQG, PM2.5 (95% CI 7,400, 17,405) | WHO AQG, O3 (95% CI 1,189, 10,840) | WHO AQG, joint pollutants (95% CI 10,148, 17,998) |
|---|---|---|---|---|
| CCAA benefit evaluation | 541 (95% CI 184–914) per 100 000 people | |||
| Threshold intervention | 13 530 | 6498 | 15 449 |
