Relationship of Smokefree Laws and Alcohol Use with Light and Intermittent Smoking and Quit Attempts among US Adults and Alcohol Users

Jiang, Nan; Gonzalez, MariaElena; Ling, Pamela M; Glantz, Stanton A
INTRODUCTION: Light and intermittent smoking (LITS) has become increasingly common. Alcohol drinkers are more likely to smoke. We examined the association of smokefree law and bar law coverage and alcohol use with current smoking, LITS, and smoking quit attempts among US adults and alcohol drinkers. METHODS: Cross-sectional analyses among a population-based sample of US adults (n = 27,731) using restricted data from 2009 National Health Interview Survey and 2009 American Nonsmokers' Rights Foundation United States Tobacco Control Database. Multivariate logistic regression models examined the relationship of smokefree law coverage and drinking frequency (1) with current smoking among all adults; (2) with 4 LITS patterns among current smokers; and (3) with smoking quit attempts among 6 smoking subgroups. Same multivariate analyses were conducted but substituted smokefree bar law coverage for smokefree law coverage to investigate the association between smokefree bar laws and the outcomes. Finally we ran the above analyses among alcohol drinkers (n = 16,961) to examine the relationship of smokefree law (and bar law) coverage and binge drinking with the outcomes. All models controlled for demographics and average cigarette price per pack. The interactions of smokefree law (and bar law) coverage and drinking status was examined. RESULTS: Stronger smokefree law (and bar law) coverage was associated with lower odds of current smoking among all adults and among drinkers, and had the same effect across all drinking and binge drinking subgroups. Increased drinking frequency and binge drinking were related to higher odds of current smoking. Smokefree law (and bar law) coverage and drinking status were not associated with any LITS measures or smoking quit attempts. CONCLUSIONS: Stronger smokefree laws and bar laws are associated with lower smoking rates across all drinking subgroups, which provides further support for these policies. More strict tobacco control measures might help reduce cigarette consumption and increase quit attempts.

Young adult social smokers: their co-use of tobacco and alcohol, tobacco-related attitudes, and quitting efforts

Jiang, Nan; Lee, Youn O; Ling, Pamela M
OBJECTIVE: Young adults frequently report social smoking. This study examined the relationship between different social smoking definitions and the co-use of cigarettes and alcohol, tobacco-related attitudes, and quitting efforts. METHOD: Cross-sectional data were collected at bars using randomized time location sampling among young adults aged 21-26 in San Diego, California from 2010 to 2011 (73% response rate). Multivariable logistic regression examined if current smoking and quit attempts were associated with tobacco-related attitudes, and whether social smoking self-identification or behavior was associated with cigarette-and-alcohol co-use, tobacco-related attitudes, quit attempts, or quitline use. RESULTS: Among 537 current smokers, 80% self-identified and 49% behaved as social smokers. Social smoking self-identification was positively associated with cigarette-and-alcohol co-use, and quit attempts. Social smoking behavior was negatively associated with tobacco marketing receptivity, quit attempts, and quitline use. Tobacco-related attitudes were associated with smoking but did not generally differ by social smoking status. CONCLUSION: Identification and behavior as a social smoker have opposing associations with co-use of cigarettes and alcohol and quit attempts. Tobacco cessation programs for self-identified social smokers should address co-use. Interventions denormalizing the tobacco industry or emphasizing the health effects of temporary smoking and secondhand smoke may address smoking among young adult bar patrons regardless of social smoking status.

Association between tobacco and alcohol use among young adult bar patrons: a cross-sectional study in three cities

Jiang, Nan; Lee, Youn Ok; Ling, Pamela M
BACKGROUND: Bars and nightclubs are key public venues where young adults congregate and use both tobacco and alcohol, and young adult bar patrons are at high risk for substance use. This study examined the association between cigarette smoking and alcohol use among a random sample of young adult bar patrons from three different cities in the USA. METHODS: Cross-sectional data was collected from a random sample of young adult bar patrons aged 18-29 in San Diego, CA (N = 1,150), Portland, ME (N = 1,019), and Tulsa, OK (N = 1,106) from 2007-2010 (response rate 88%) using randomized time location sampling. Respondents reported the number of days they smoked cigarettes, drank alcohol, and binge drank in the past 30 days. Multinomial logistic regression was used to analyze the association between smoking (nonsmoker, occasional smoker, and regular smoker) and drinking and binge drinking for each city controlling for age, gender, race/ethnicity, and education. Predicted probabilities of each smoking category were calculated by drinking and binge drinking status. The association between smoking and drinking and binge drinking among combined samples was also analyzed, controlling for demographic variables and city. RESULTS: Respondents reported high current smoking rates, ranging from 51% in Portland to 58% in Tulsa. Respondents in Tulsa were more likely to report regular smoking than those in San Diego and Portland, with demographic variables being controlled. Young adult bar patrons also exhibited a strong association between smoking and drinking. In general, as the frequency of drinking and binge drinking increased, the predicted probability of being a smoker, especially a regular smoker, increased in each city. CONCLUSIONS: Young adult bar patrons consistently reported a high smoking rate and a strong relationship between smoking and drinking, regardless of the different bar cultures and tobacco control contexts in each of the three cities. While smoke-free bar policies were negatively associated with regular smoking, these policies alone may not be enough to influence the association between smoking and drinking, particularly if tobacco marketing continues in these venues, or in the absence of programs specifically addressing the co-use of tobacco and alcohol.

Vested Interests in addiction research and policy. Alliance between tobacco and alcohol industries to shape public policy [Historical Article]

Jiang, Nan; Ling, Pamela
AIMS: The tobacco and alcohol industries share common policy goals when facing regulation, opposing policies such as tax increases and advertising restrictions. The collaboration between these two industries in the tobacco policy arena is unknown. This study explored if tobacco and alcohol companies built alliances to influence tobacco legislation and, if so, how those alliances worked. METHODS: Analysis of previously secret tobacco industry documents. FINDINGS: In the early 1980s, tobacco companies started efforts to build coalitions with alcohol and other industries to oppose cigarette excise taxes, clean indoor air policies and tobacco advertising and promotion constraints. Alcohol companies were often identified as a key partner and source of financial support for the coalitions. These coalitions had variable success interfering with tobacco control policy-making. CONCLUSIONS: The combined resources of tobacco and alcohol companies may have affected tobacco control legislation. These alliances helped to create the perception that there is a broader base of opposition to tobacco control. Advocates should be aware of the covert alliances between tobacco, alcohol and other industries and expose them to correct this misperception.

Impact of alcohol use and bar attendance on smoking and quit attempts among young adult bar patrons

Jiang, Nan; Ling, Pamela M
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.

Reinforcement of smoking and drinking: tobacco marketing strategies linked with alcohol in the United States

Jiang, Nan; Ling, Pamela M
OBJECTIVES: We investigated tobacco companies' knowledge about concurrent use of tobacco and alcohol, their marketing strategies linking cigarettes with alcohol, and the benefits tobacco companies sought from these marketing activities. METHODS: We performed systematic searches on previously secret tobacco industry documents, and we summarized the themes and contexts of relevant search results. RESULTS: Tobacco company research confirmed the association between tobacco use and alcohol use. Tobacco companies explored promotional strategies linking cigarettes and alcohol, such as jointly sponsoring special events with alcohol companies to lower the cost of sponsorships, increase consumer appeal, reinforce brand identity, and generate increased cigarette sales. They also pursued promotions that tied cigarette sales to alcohol purchases, and cigarette promotional events frequently featured alcohol discounts or encouraged alcohol use. CONCLUSIONS: Tobacco companies' numerous marketing strategies linking cigarettes with alcohol may have reinforced the use of both substances. Because using tobacco and alcohol together makes it harder to quit smoking, policies prohibiting tobacco sales and promotion in establishments where alcohol is served and sold might mitigate this effect. Smoking cessation programs should address the effect that alcohol consumption has on tobacco use.

Health of adolescents and young adults: trends in achieving the 21 Critical National Health Objectives by 2010

Jiang, Nan; Kolbe, Lloyd J; Seo, Dong-Chul; Kay, Noy S; Brindis, Claire D
PURPOSE: The 21 Critical National Health Objectives (CNHOs) for Adolescents and Young Adults derived from Healthy People 2010 addressed the most significant threats to the health of individuals aged 10-24 years. This study assessed trends in the 21 CNHOs between 1991 and 2009, and from baseline years for which 2010 targets were established to 2009, and the extent to which targets were achieved. METHODS: For one CNHO (new HIV diagnoses), national data were not available. For CNHOs measured by census systems, the percentage of change in each health outcome was calculated between 1991 and 2009 and between baseline years and 2009. Any change >/=5% was considered as an improvement or deterioration. For CNHOs measured by national probability-based surveillance surveys, multivariate logistic regression was conducted using Stata Version 10.0 (StataCorp, College Station, TX) to calculate odds ratios for each outcome from 1991, and from baseline years to 2009, controlling for gender, race/ethnicity, and age or school grade-level. To calculate the percentage of targets being achieved, the difference between baseline data and 2009 data was divided by that between baseline data and target. RESULTS: Adolescents and young adults achieved two targets (rode with a driver who had drunk alcohol, physical fighting), improved for 12 CNHOs, made mixed progress by sub-objective for two, showed no progress in four, and regressed in achieving two (Chlamydia infections; overweight). Progress varied by demographic variables. CONCLUSION: Although encouraging trends were seen in young people's health, the United States achieved only two CNHOs. Attention is needed to improve the health and reduce disparities among young people.

Transnational tobacco industry promotion of the cigarette gifting custom in China

Chu, Alexandria; Jiang, Nan; Glantz, Stanton A
OBJECTIVE: To understand how British American Tobacco (BAT) and Philip Morris (PM) researched the role and popularity of cigarette gifting in forming relationships among Chinese customs and how they exploited the practice to promote their brands State Express 555 and Marlboro. METHODS: Searches and analysis of industry documents from the Legacy Tobacco Documents Library complemented by searches on LexisNexis Academic news, online search engines and information from the tobacco industry trade press. RESULTS: From 1980-1999, BAT and PM employed Chinese market research firms to gather consumer information about perceptions of foreign cigarettes and the companies discovered that cigarettes, especially prestigious ones, were gifted and smoked purposely for building relationships and social status in China. BAT and PM promoted their brands as gifts by enhancing cigarette cartons and promoting culturally themed packages, particularly during the gifting festivals of Chinese New Year and Mid-Autumn Festival to tie their brands in to festival values such as warmth, friendship and celebration. They used similar marketing in Chinese communities outside China. CONCLUSIONS: BAT and PM tied their brands to Chinese cigarette gifting customs by appealing to social and cultural values of respect and personal honour. Decoupling cigarettes from their social significance in China and removing their appeal would probably reduce cigarette gifting and promote a decline in smoking. Tobacco control efforts in countermarketing, large graphic warnings and plain packaging to make cigarette packages less attractive as gifts could contribute to denormalising cigarette gifting.

Associations between smoking and extreme dieting among adolescents

Seo, Dong-Chul; Jiang, Nan
This study examined the association between cigarette smoking and dieting behaviors and trends in that association among US adolescents in grades 9-12 between 1999 and 2007. Youth Risk Behavior Survey datasets were analyzed using the multivariable logistic regression method. The sample size of each survey year ranged from 13,554 to 15,273 with girls representing 49-51% of the sample (N = 71,854). About 62% of the entire study participants were whites and 14% were blacks. Prevalence estimates of current smoking and corresponding 95% confidence intervals were computed across four comparison groups formed by gender and body weight. Extreme dieting was an independent predictor of smoking. Extreme dieters showed a higher variability of smoking behavior than their peers. The magnitude of the association between smoking and extreme dieting became smaller in recent years among adolescents but remained unchanged among non-overweight girls over that same time period. When adolescent smoking behavior is examined, the intensity of dieting behavior should be considered within its association with other co-occurring unhealthy behaviors.

Correlates of college students' physical activity: cross-cultural differences

Seo, Dong-Chul; Torabi, Mohammad R; Jiang, Nan; Fernandez-Rojas, Xinia; Park, Bock-Hee
This study examined cross-cultural differences in personal and behavioral determinants of vigorous-intensity and moderate-intensity physical activity (PA) among college students living in distinctly different cultures, that is, the United States, Costa Rica, India, and South Korea. Participants of this study were recruited from randomly chosen public universities in the 4 countries during the 2006-2007 academic year. A total of 4685 students participated in the study (response rate 90%). Vigorous-intensity PA was measured by asking on how many of the past 7 days the participants participated in PA for at least 20 minutes that made them sweat or breathe hard. For moderate-intensity PA, participants were asked on how many of the past 7 days they participated in PA for at least 30 minutes that did not make them sweat or breathe hard. Findings indicate that whereas perceived overweight and fruit and vegetable consumption are relatively culture-free predictors of PA, gender and TV/video watching are culture-specific predictors. Binge drinking was not predictive of meeting the vigorous-intensity and moderate-intensity PA guidelines in any of the 4 countries.
