Résumé
Objective To understand the knowledge and attitudes towards second hand smoking(SHS) among restaurant or bar patronage in five cities in China. Methods 405 restaurants and bars were conveniently selected in 5 cities as Beijing, Wuhan, Xi'an, Kunming and Guiyang. From each of these hospitality venues, at least 3 patrons, including one smoker, one female non-smoker and one male nonsmoker were asked to answer a questionnaire on their knowledge and attitudes towards SHS and smoking policies in public places. Results 43.1% of the respondents had good knowledge on SHS hazards. 65%reported that those who smoked around them had never asked for their permission, and about 60%admitted that they had never asked others to stop smoking in front of them. There were almost two thirds of patrons reporting that they once felt discomfort of SHS in restaurants or bars, nearly half of whom chose free restaurants and bars' initiations were only 30.0% and 19.8%, respectively. In Beijing, logistic regression model analyses showed that those who supporting 100 % smoke-free restaurants and bars tended to be non-smokers, aged 25 years or older and to have had at least college education. Also in Beijing, those being female, having at least college education or non-smokers were more likely to choose restaurants and bars with smoking restrictions. Conclusion Though knowledge on SHS hospitality patronage was still not high or popular for the public to refuse SHS exposure, banning smoking in hospitality venues was public's inclination and would become a trend in public health endeavor.
