Hypothesis
What is the global burden of cardiovascular disease mortality attributable to secondhand smoke from 1990 to 2019?
Conclusion
Over the past three decades, the epidemiological landscape of cardiovascular disease mortality associated with secondhand smoke has undergone significant shifts, with a global decline but rising rates in specific regions.
Supporting Evidence
- Global age-standardized mortality rate for CVD due to secondhand smoke decreased from 11.45 to 7.43 per 100,000 population from 1990 to 2019.
- DALYs for CVD due to secondhand smoke decreased from 274.12 to 176.93 per 100,000 population in the same period.
- 47 countries showed an increase in ASMR and DALYs attributable to secondhand smoke.
- Uzbekistan, Lesotho, and the Philippines had the highest annual average percentage change for CVD due to secondhand smoke.
Takeaway
This study looked at how secondhand smoke affects heart disease deaths around the world. While things have improved overall, some places are still seeing more deaths from it.
Methodology
The study used a systematic analysis design with data from the Global Burden of Disease Study 2019, focusing on age-standardized mortality rates and disability-adjusted life years for cardiovascular disease due to secondhand smoke.
Potential Biases
Potential biases may arise from data incompleteness and inaccuracies.
Limitations
The study is based on observational data, which does not establish causality, and lacks granular regional data to identify local factors contributing to the rise in CVD mortality.
