A Nationwide Analysis of US Racial/Ethnic Disparities in Smoking Behaviors, Smoking Cessation, and Cessation-Related Factors

OBJECTIVES We used nationally representative data to examine racial/ethnic disparities in smoking behaviors, smoking cessation, and factors associated with cessation among US adults. METHODS We analyzed data on adults aged 20 to 64 years from the 2003 Tobacco Use Supplement to the Current Population Survey, and we examined associations by fitting adjusted logistic regression models to the data. RESULTS Compared with non-Hispanic Whites, smaller proportions of African Americans, Asian Americans/Pacific Islanders, and Hispanics/Latinos had ever smoked. Significantly fewer African Americans reported long-term quitting. Racial/ethnic minorities were more likely to be light and intermittent smokers and less likely to smoke within 30 minutes of waking. Adjusted models revealed that racial/ethnic minorities were not less likely to receive advice from health professionals to quit smoking, but they were less likely to use nicotine replacement therapy. CONCLUSIONS Specific needs and ideal program focuses for cessation may vary across racial/ethnic groups, such that approaches tailored by race/ethnicity might be optimal. Traditional conceptualizations of cigarette addiction and the quitting process may need to be revised for racial/ethnic minority smokers.

Intermittent and light daily smoking across racial/ethnic groups in the United States

INTRODUCTION Limited research exists examining the prevalence of intermittent (nondaily) and light daily (1-5 cigarettes/day) smoking across racial/ethnic groups in the United States using nationally representative data. These analyses would be informative in guiding targeted cessation strategies. METHODS Using logistic regression models controlling for age, gender, and education, we examined the prevalence of intermittent and light daily consumption among current smokers across racial/ethnic groups from the 2003 Tobacco Use Supplement to the Current Population Survey. We also examined the association of these demographic factors with consumption within each racial/ethnic group separately. RESULTS Black (odds ratio [OR] = 1.82, 95% CI = 1.59-2.07), Asian/Pacific Islander (OR = 1.62, 95% CI = 1.29-2.04), and Hispanic/Latino (OR = 3.2, 95% CI = 2.75-3.74) smokers were more likely to smoke intermittently compared with non-Hispanic Whites. Black (OR = 2.69, 95% CI = 2.27-3.18), Asian/Pacific Islander (OR = 2.99, 95% CI = 2.13-4.19), and Hispanic/Latino (OR = 4.64, 95% CI = 3.85-5.58) smokers also were more likely to have light daily consumption compared with non-Hispanic Whites. Hispanic/Latino intermittent smokers smoked fewer days per month and fewer cigarettes per day compared with non-Hispanic White smokers. We found no significant gender differences across racial/ethnic groups in intermittent smoking, but male smokers were significantly less likely to have light daily consumption for all racial/ethnic groups. DISCUSSION These results have implications for the understanding of the tobacco dependence, the development of prevention and cessation strategies, and the applicability of harm-reduction techniques for racial/ethnic minorities.

Receptivity to Tobacco Advertising and Promotions Among Young Adolescents as a Predictor of Established Smoking in Young Adulthood

OBJECTIVES We investigated whether receptivity to tobacco advertising and promotions during young adolescence predicts young adult smoking 6 years later. METHODS Two longitudinal cohorts of adolescents drawn from the 1993 and 1996 versions of the California Tobacco Surveys were followed 3 and 6 years later. At baseline, adolescents were aged 12 to 15 years and were not established smokers. The outcome measure was established smoking at final follow-up. Receptivity to cigarette advertising and promotions was included in a multivariate logistic regression analysis along with demographic and other variables. RESULTS The rate of established smoking at follow-up was significantly greater among members of the 1993 through 1999 cohort (21.0%) than among members of the 1996 through 2002 cohort (15.6%). However, in both cohorts, having a favorite cigarette advertisement and owning or being willing to use a tobacco promotional item showed nearly identical adjusted odds of future adult smoking (1.46 and 1.84, respectively). CONCLUSIONS Despite the success of tobacco control efforts in reducing youth smoking, tobacco marketing remains a potent influence on whether young adolescents become established smokers in young adulthood (18-21 years of age).

Prevalence of heavy smoking in California and the United States, 1965-2007

CONTEXT The intensity of smoking, not just prevalence, is associated with future health consequences. OBJECTIVE To estimate smoking intensity patterns over time and by age within birth cohorts for California and the remaining United States. DESIGN, SETTING, AND PARTICIPANTS Two large population-based surveys with state estimates: National Health Interview Surveys, 1965-1994; and Current Population Survey Tobacco Supplements, 1992-2007. There were 139,176 total respondents for California and 1,662,353 for the remaining United States. MAIN OUTCOME MEASURE Number of cigarettes smoked per day (CPD), high-intensity smokers (≥20 CPD); moderate-intensity smokers (10-19 CPD); low-intensity smokers (0-9 CPD). RESULTS In 1965, 23.2% of adults in California (95% confidence interval [CI], 19.6%-26.8%) and 22.9% of adults in the remaining United States (95% CI, 22.1%-23.6%) were high-intensity smokers, representing 56% of all smokers. By 2007, this prevalence was 2.6% (95% CI, 0.0%-5.6%) or 23% of smokers in California and 7.2% (95% CI, 6.4%-8.0%) or 40% of smokers in the remaining United States. Among individuals (US residents excluding California) born between 1920-1929, the prevalence of moderate/high-intensity smoking (≥10 CPD) was 40.5% (95% CI, 38.3%-42.7%) in 1965. Moderate/high-intensity smoking declined across successive birth cohorts, and for the 1970-1979 birth cohort, the highest rate of moderate/high-intensity smoking was 9.7% (95% CI, 7.7%-11.7%) in California and 18.3% (95% CI, 16.4%-20.2%) in the remaining United States. There was a marked decline in moderate/high-intensity smoking at older ages in all cohorts, but this was greater in California. By age 35 years, the prevalence of moderate/high-intensity smoking in the 1970-1979 birth cohort was 4.6% (95% CI, 3.0%-6.1%) in California and 13.5% (95% CI, 11.8%-15.1%) in the remaining United States. CONCLUSIONS Between 1965 and 2007, the prevalence of high-intensity smoking decreased greatly in the United States. The greater decline in high-intensity smoking prevalence in California was related to reduced smoking initiation and a probable increase in smoking cessation.

Does tobacco marketing undermine the influence of recommended parenting in discouraging adolescents from smoking

OBJECTIVE The tobacco industry contends that parenting practices, not marketing practices, are critical to youth smoking. Our objective was to examine whether tobacco-industry marketing practices undermine the protective effect of recommended authoritative parenting against adolescent smoking. DESIGN AND SETTING Receptivity to tobacco advertising and promotions was assessed in 1996 from a representative sample of California adolescent never-smokers aged 12 to 14 years. A follow-up survey of 1641 of these adolescents was conducted in 1999 that included measures of the key components of authoritative parenting: parental responsiveness, monitoring, and limit setting. MAIN OUTCOME MEASURE Smoking initiation in adolescents. RESULTS Adolescents in families with more-authoritative parents were half as likely to smoke by follow-up as adolescents in families with less-authoritative parents (20% vs 41%, p <0.0001). In families with more-authoritative parents, adolescents who were highly receptive to tobacco-industry advertising and promotions were significantly more likely to smoke (odds ratio=3.52, 95% confidence interval =1.10-11.23), compared to those who were minimally receptive. This effect was not significant in adolescents in families with less-authoritative parents. The overall attributable risk (adjusted for exposure to peer smokers) of smoking from tobacco-industry advertising and promotions was 25%. However, an estimated 40% of adolescent smoking in families with more-authoritative parents was attributable to tobacco-industry advertising and promotions; this was five times the attributable risk seen in families with less-authoritative parents (8%). CONCLUSION The promotion of smoking by the tobacco industry appears to undermine the capability of authoritative parenting to prevent adolescents from starting to smoke.

Changing age-specific patterns of cigarette consumption in the United States, 1992–2002: Association with smoke-free homes and state-level tobacco control activity

INTRODUCTION During the 1990s, both prevalence and average cigarette consumption declined in the United States, but age-specific changes have not been reported. METHOD All four of the nationally and state representative U.S. Current Population Surveys-Tobacco Use Supplements from 1991-2002 (n = 542,470) were analyzed for trends in cigarette consumption among smokers in three age groups: 18-29, 30-44, and 45-64 years. A strength of tobacco control index ranking state of residence was added and weighted logistic regression analyses undertaken. RESULTS Over the decade, both prevalence and average consumption declined. Moderate-heavy smoking (> or =15 cigarettes/day [CPD]) prevalence fell strongly over the period in all three age groups. For those aged > or =30 years, this reduction was accompanied by a similar drop in total smoking prevalence. For those aged 18-29 years, this reduction was associated with an increase in very light smoking (<5 CPD; 12% daily and 88% intermittent smokers) to 22.5% of current smokers with a much smaller reduction in prevalence. Smoke-free homes more than doubled in each age group and mediated the increase in very light smoking levels. Smoke-free workplaces and the strength of tobacco control in the state were also important predictors. Very light smoking was particularly prevalent among college students and graduates. DISCUSSION The marked reduction in prevalence of moderate-heavy smoking across age groups should translate into a reduced population risk of smoking-related disease in the near term. That this reduction is offset by an increase in light and intermittent smoking in young adults suggests the effectiveness of tobacco industry marketing and needs further research.

The effect of smoke-free homes on smoking behavior in the U.S.

BACKGROUND Evidence from longitudinal population surveys is needed to establish whether smoke-free homes might influence smoking behavior. METHODS The Tobacco Use Supplement of the nationally representative U.S. Current Population Survey (TUS-CPS) interviewed 3292 adult recent smokers in 2002 and again 12 months later. Both surveys measured smoking status, rules on smoking in the home, and the number of cigarettes smoked per day (cpd). For the main study outcome, an early marker of successful cessation (>or=90 days quit) was used. Analysis was completed in 2008. RESULTS In the 12 months ending February 2003, the prevalence of smoke-free homes among recent smokers increased from 33% to 39%. A smoke-free home at baseline was associated with >or=90 days cessation at follow-up (10.9% vs 6.2%, AOR=1.44; 95% CI=0.97, 2.21), and those who maintained a smoke-free home were more likely to be >or=90 days quit than those who did not (12.9% vs 5.7%, AOR=1.99; 95% CI=0.93, 4.25). However, adopting a smoke-free home during the year was associated with a nearly fivefold increase in the percentage of >or=90 days quit (AOR=4.81; 95% CI=3.06, 7.59). This increase was seen among all smokers, including moderate-to-heavy smokers (>or=90 days quit: a smoke-free home=13.0% vs no smoke-free home=2.9%, p<0.001). Among continuing smokers with a smoke-free home at baseline, maintenance of te smoke-free home was associated with a decline in consumption (micro=or-2.18; 95 CI=or-1.24; -3.10 cpd). Among continuing smokers with no smoke-free home at baseline, adoption of that status was also associated with a decline in consumption (micro=or-1.72; 95% CI=or-0.58; -2.85 cpd). CONCLUSIONS This study provides strong evidence that the adoption of a smoke-free home is associated with successful quitting among smokers in the U.S.

Increasing Hookah Use in California

Hookah use is gaining popularity nationwide. We determined the correlates and trends for hookah use from the California Tobacco Survey. Between 2005 and 2008 hookah use increased more than 40%, and in 2008, 24.5% of young men reported ever using a hookah. Hookah use was more common among the young (18-24 years), the educated, the non-Hispanic Whites, and the cigarette smokers. Hookah use is increasing in California, especially among young adults, and in 2008 reached the highest prevalence ever reported for both genders.

Home smoking bans among U.S. households with children and smokers. Opportunities for intervention.

BACKGROUND Public health campaigns have reduced the exposure of U.S. children to secondhand smoke at home; however, these may not have been equally effective across subgroups. PURPOSE To examine prevalence of home smoking bans among U.S. households with both children and smokers, over time and by demographic subgroups. METHODS The Tobacco Use Supplement to the Current Population Survey (TUS-CPS) is a nationally representative household survey of tobacco use. The 1992/1993 and 2006/2007 TUS-CPS interviewed 22,746 households from a major racial/ethnic group with both children and adult smokers. Predictors of complete home smoking bans among demographic subgroups were identified using multivariate logistic regression. Analyses were conducted in 2010-2011. RESULTS Complete home smoking bans among U.S. households with children and smokers (smoking families) more than tripled, from 14.1% in 1992/1993 to 50.0% in 2006/2007. However, non-Hispanic white and African-American smoking families lagged behind Asian/Pacific Islanders and Hispanics. In 2006/2007, 67.2% of African-American smoking families allowed smoking in the home, as did 59.2% of smoking families with all children aged ≥14 years. Bans were more likely among more-educated households and in states with lower adult smoking prevalence; however, these differences were attenuated in some racial/ethnic groups. CONCLUSIONS As of 2006/2007, only half of U.S. households with both children and smokers had complete home smoking bans. Home bans were less common among smoking families with older children, in African-American households, and in Hispanic or non-Hispanic white households in states with high smoking prevalence. Interventions are needed to promote smoke-free homes among these groups.

Menthol cigarettes and smoking cessation among racial/ethnic groups in the United States.

AIM To examine the association between smoking mentholated cigarettes and smoking cessation, separately for different racial/ethnic groups. DESIGN Secondary data analysis of the 2003 and 2006-07 Tobacco Use Supplements to the Current Population Survey. SETTING United States. PARTICIPANTS African American, Asian American/Pacific Islander, Hispanic/Latino, Native American, non-Hispanic white adults. MEASUREMENTS Examined relations between the use of mentholated cigarettes and measures of smoking cessation. FINDINGS Among African Americans (ORadj = 1.62, 95% CI: 1.35-1.95) and Hispanics/Latinos (ORadj = 1.21, 95% CI: 1.00-1.47), those who currently smoked mentholated cigarettes were more likely be seriously considering quitting in the next six months than were non-menthol smokers, after adjusting for sociodemographic factors. African Americans (ORadj = 1.87, 95% CI: 1.60-2.19) and Hispanics/Latinos (ORadj = 1.34, 95% CI: 1.11-1.62) who smoked mentholated cigarettes were also significantly more likely to have a positive estimation of successfully quitting in the next six months compared to non-menthol smokers. These associations were not found among Asian Americans/Pacific Islanders, Native Americans/Alaska Natives and Non-Hispanic Whites. Among former smokers, across racial/ethnic groups, those who smoked mentholated cigarettes (vs. non-menthols) were significantly less likely to have successfully quit for at least six months: African Americans (ORadj = 0.23, 95% CI: 0.17-0.31), Asian Americans/Pacific Islanders (ORadj = 0.22, 95% CI: 0.11-0.45), Hispanics/Latinos (ORadj = 0.48, 95% CI: 0.34-0.69) and Non-Hispanic Whites (ORadj = 0.28, 95% CI: 0.25-0.33). CONCLUSION Across race/ethnic groups, those who used to regularly smoke mentholated cigarettes were less likely to have experienced long-term quitting success. Cessation programs should consider the type of cigarette typically smoked by participants, particularly menthols.
