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 a 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.
