摘要：Objectives. We examined cigarette smoking and quit attempts in the context of alcohol use and bar attendance among young adult bar patrons with different smoking patterns. Methods. We used randomized time location sampling to collect data among adult bar patrons aged 21 to 26 years in San Diego, California (n = 1235; response rate = 73%). We used multinomial and multivariate logistic regression models to analyze the association between smoking and quit attempts and both drinking and binge drinking among occasional, regular, very light, and heavier smokers, controlling for age, gender, race/ethnicity, and education. Results. Young adult bar patrons reported high rates of smoking and co-use of cigarettes and alcohol. Binge drinking predicted smoking status, especially occasional and very light smoking. All types of smokers reported alcohol use, and bar attendance made it harder to quit. Alcohol use was negatively associated with quit attempts for very light smokers, but positively associated with quitting among heavier smokers. Conclusions. Smoking and co-use of cigarettes and alcohol are common among young adult bar patrons, but there are important differences by smoking patterns. Tobacco interventions for young adults should prioritize bars and address alcohol use. Tobacco is responsible for approximately 443 000 deaths in the United States annually, 1,2 but cessation before the age of 30 years avoids most of the long-term health consequences of smoking. 3 As smoking prevalence has declined, 4 nondaily smoking and low-level daily cigarette consumption, 5–7 also referred to as occasional or light smoking patterns, have increased. 8–11 Nondaily smokers made up 4.1% of the US adult population in 2006, 12 increasing from 3.2% in 1997 and 1998. 6 Nondaily smokers accounted for 19.9% of current smokers in 2006, 12 increasing from 16.0% in 1997 and 1998. 6 Younger age is associated with occasional smoking, 9,13 and nondaily smoking is common among young adults. In 1997 and 1998, 5.5% of young adults aged 18 to 24 years were nondaily smokers, accounting for 19.9% of young adult smokers, the highest proportion of nondaily smoking among all age groups. 6 Alcohol complicates occasional or light smoking in young adults, and it often plays a powerful catalyst role in facilitating and maintaining smoking. 14 Young adults report that alcohol increases the enjoyment of and desire for cigarettes, 15,16 and tobacco enhances the desired effect of alcohol. 17–19 The co-use of cigarettes and alcohol has been described as like “milk and cookies” or “peanut butter with jelly.” 20 The co-use of tobacco and alcohol among young adults 15,21,22 poses a serious health threat. Use of both cigarettes and alcohol increases the risk for certain cancers (e.g., mouth, throat, esophagus, upper aerodigestive tract) 23–25 and makes it more difficult to quit either substance. 26–28 In a 2001–2002 national study, 2.9% of adults aged 18 years and older (6.2 million) reported both alcohol use disorders and a dependence on nicotine by Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition ( DSM-IV ) criteria, and young adults aged 18 to 24 years exhibited the highest rates of this comorbidity. 22 Bars and nightclubs are key public venues where young adults congregate and use both alcohol and tobacco. Tobacco companies have targeted young adults, using entertaining events to reinforce a smoker-friendly atmosphere in bars and nightclubs. 16,29–31 Many tobacco marketing events have encouraged alcohol use by offering alcohol discounts, paraphernalia, or by holding alcohol drinking contests. 16,29,30,32 The strong rewarding effects of nicotine paired with alcohol, 33–35 the aggressive tobacco marketing linked with alcohol, 32 and the peer acceptance of smoking while drinking at parties in bars and nightclubs 20 have put young adult bar patrons at high risk for tobacco use and co-use of tobacco and alcohol, even for occasional and light smokers. To our knowledge, no study has examined the co-use of tobacco and alcohol among young adult bar patrons. This is a hard-to-reach population often underrepresented in national surveillance studies. Additionally, no study has assessed co-use behavior among young adult occasional and light smokers, an increasingly common behavior. We examined patterns of smoking and quit attempts in the context of alcohol use and bar attendance among 4 groups of young adult smokers attending bars in San Diego, California, including occasional, regular, very light, and heavier smokers.
