Association Between Secondhand Smoke Exposure Among Women and the Implementation of Tobacco Control Measures on Campus: A Cross-Sectional Study in 50 Universities Across China.

Approximately half of female college students are exposed to SHS on campus in China. Failure to implement smoke-free policies and exposure to tobacco marketing on campus are associated with higher SHS exposure. To protect millions of young Chinese women from the health harms of SHS, universities need to enact and enforce smoke-free policies within campus boundaries and adopt comprehensive bans on tobacco advertising and promotion on campus.
