Environmental secondhand smoke exposure and policy assessment at five venues in Zhejiang Province, China.

ABSTRACT

The objective of this study was to assess environmental secondhand smoke exposure and tobacco control policy at 5 venues. A cross-sectional study was conducted involving 134 settings and 2727 adults in Zhejiang, China. The results show that the proportions of venues that had complete smoking ban were as follows health administrative organizations (71.9%), hospitals (70.0%), schools (66.7%), public transportation vehicles (24.0%), and government agencies (11.8%). The proportions of venues where smoking was noticed were as follows public transportation vehicles (88.0%), government agencies (47.1%), hospitals (46.7%), health administrative organizations (40.6%), and schools (30.0%). Venues with completely indoor smoking ban were 5 times more likely to be smoke-free at the time of survey than other venues without smoking ban (odds ratio = 5.39, 95% confidence interval = 1.92-15.14). It indicated that implementation of indoor smoking ban can reduce indoor secondhand smoke exposure.
