Abstract
What is already known about this topic?: In 2018, the secondhand smoke (SHS) exposure rate among non-smoking adults aged 15 years and above in China was 68.1%.
What is added by this report?: In 2022, the SHS exposure rate among non-smoking adults aged 15 years and above in China was 52.4%, with significant positive spatial correlation across regions. Key factors influencing regional SHS exposure included smoking rates, tobacco control measures in homes, indoor workplaces, and healthcare institutions, proportion of the population covered by comprehensive smoke-free regulations, and public awareness of SHS and smoking-related health risks.
What are the implications for public health practice?: Understanding the spatial heterogeneity and determinants of SHS exposure provides crucial insights for developing targeted, region-specific tobacco control strategies and interventions.
