Background: Young adults still initiate smoking, and cessation before age 30 eliminates most negative health effects. We described frequency of SHS exposure among young adults attending bars and associations between SHS exposure, attitudes and smoking behavior.

Methods: Randomized time-location samples of bar-going young adults aged 18-26 in San Diego, CA (N=1305) and Oklahoma City (OKC) (N=1264) and Tulsa (N=1250), OK completed cross-sectional surveys from Sept 2010 to July 2011. Multivariate logistic regression evaluated associations between SHS exposure, attitudes about dangers of SHS, and (1) intention to quit among current smokers, and (2) susceptibility to start smoking among nonsmokers, controlling for demographic variables.

Results: Over 90% of all respondents reported past 7 day exposure to any SHS, and over 70% reported exposure in a bar (73.2% in San Diego, 79.7% in OKC, and 75% in Tulsa). Exposure in was lower in San Diego than in Oklahoma. Exposure to SHS at home was negatively associated with attempts to quit in daily smokers (OR=0.70 95%CI [0.51, 0.96]). Believing SHS is dangerous was significantly associated with quit attempts among smokers (OR=1.27 [1.03,1.57]). Among nonsmokers, any SHS exposure was associated with susceptibility to start smoking (OR=1.66 [1.12, 2.47]), but those with beliefs that SHS exposure was harmful were significantly less susceptible to start smoking (OR=0.345 [0.28, 0.43]).

Conclusions: Young adults attending bars report frequent SHS exposure. Rates were significantly lower in California, but higher than statewide reports. Promoting smokefree environments and education on the harmful effects of SHS may decrease tobacco use in this population.
