Summary
Secondhand smoke exposure significantly decreased in China from 2010 to 2015, with notable declines in public spaces and homes. Public awareness of smoking hazards and support for smoke-free policies are rising.
Area of Science:
- Public Health
- Tobacco Control
- Epidemiology
Background:
- China's commitment to the WHO Framework Convention on Tobacco Control.
- Initiatives to reduce secondhand smoke exposure.
- Focus on changes in non-smoker exposure between 2010 and 2015.
Purpose of the Study:
- To analyze trends in secondhand smoke exposure among non-smokers in China.
- To assess changes in exposure across various public and private settings.
- To evaluate shifts in public awareness and policy support.
Main Methods:
- Utilized data from the 2010 Global Adult Tobacco Survey and 2015 National Adult Tobacco Survey.
- Employed weighted analysis using SAS 9.3 complex survey data procedures.
- Conducted Chi-square tests for group comparisons.
Main Results:
- Significant reductions in secondhand smoke exposure observed in restaurants, government buildings, healthcare facilities, schools, and public transport (p<0.05).
- Greatest relative decreases in schools (52.1%), public transport (49.4%), and government buildings (42.2%).
- Exposure declined at home (58.3% to 46.7%) and workplaces (55.2% to 45.3%). Public awareness of health risks increased (24.6% to 36.0%), with strong support for smoke-free policies.
Conclusions:
