ABSTRACT
Objective To estimate the status of secondhand smoke (SHS) among restaurant customers in Shanghai and evaluate their support to smoke-free restaurants. Methods A random sample of 284 customers from 27 restaurants participated in the face to face interview. Results There were 55.8% smoking customers often smoke in the restaurants and 84.4% nonsmoking customers had suffered from secondhand smoke in restaurants. Among the customers, 73.9% supported the smoke-free law in restaurants and 49.6% of them expressed that they would more likely to go and eat in the restaurant after the smoke-free law implemented. Elder age, nonsmoking as well as college and above education background were the supporting factors for the smoke-free restaurants and the odds ratios were 1.03 (95%CI: 1.01~1.06), 6.40 (3.06~13.88) and 2.71 (1.44~5.11), respectively. Conclusion Customers have seriously suffered from SHS and most of them support the smoke-free policy. In general, the smoke-free restaurant policy will increase the intention of eating in the restaurants among customers.
