We described frequency of secondhand smoke (SHS) exposure among young adults patronizing bars and associations between SHS exposure, attitudes, and smoking behavior.
We collected cross-sectional surveys from randomized time-location samples of bar patrons aged 18 to 26 years in San Diego, California, and Oklahoma City and Tulsa, Oklahoma, in 2010 to 2011. Multivariate logistic regression evaluated associations between SHS exposure, attitudes about dangers of SHS, susceptibility to smoking initiation among nonsmokers, and quit attempts among current smokers.
More than 80% of respondents reported past 7-day exposure to any SHS, and more than 70% reported exposure at a bar. Current smokers reported more SHS exposure in cars and their own homes than did nonsmokers. Among nonsmokers, SHS exposure was associated with susceptibility to initiation, but those who believed that SHS exposure is harmful were less susceptible. Belief that SHS is dangerous was associated with quit attempts among smokers.
Smoke-free environments and education about the harms of SHS may decrease tobacco use among young adults who frequent bars, where they are heavily exposed to SHS.
我们描述了光顾酒吧的年轻成年人接触二手烟（SHS）的频率，以及 SHS 暴露、态度和吸烟行为之间的关系。
我们于 2010 年至 2011 年在加利福尼亚州圣地亚哥和俄克拉荷马州俄克拉荷马城及塔尔萨，从酒吧顾客的随机时间-地点样本中收集了横断面调查。多变量逻辑回归评估了 SHS 暴露、对 SHS 危害的态度、非吸烟者开始吸烟的易感性以及当前吸烟者戒烟尝试之间的关联。
超过 80%的受访者报告过去 7 天内接触过任何 SHS，超过 70%的受访者报告在酒吧接触过 SHS。与不吸烟者相比，当前吸烟者在车内和自己家中报告的 SHS 暴露更多。在不吸烟者中，接触 SHS 与开始吸烟的易感性有关，但那些认为 SHS 暴露有害的人则不易感性。认为 SHS 有危险与吸烟者的戒烟尝试有关。
在年轻人经常光顾的酒吧中，建立无烟环境和对 SHS 危害的教育可能会减少烟草使用，他们在那里大量接触 SHS。
