Progression to established smoking: the influence of tobacco marketing.

BACKGROUND: Recent studies have shown that tobacco advertising leads to the onset of smoking among adolescents. However, much more still remains to be learned about the impact of tobacco advertising in the later transitions, mainly from experimentation to established smoking. In this study, we focused on the influence of tobacco advertising and promotions on the transition from experimentation to established smoking. METHODS: Data were derived from a longitudinal survey of adolescents in California. Adolescents who were classified as experimenters at baseline were included in the analyses (N=965). Receptivity to tobacco advertising and promotions refers to the development of a positive affective response to the communication (e.g., having a favorite tobacco advertisement or being willing to use a promotional item). RESULTS: Approximately 32% of adolescents who were experimenters at baseline in 1993, progressed to established smoking by follow-up in 1996. Progression was higher among Caucasian (37.3%) than Hispanic (21.9%) or African-American (17.6%) adolescents. Adolescents who perceived that most of their peers smoked, had poor relationships with family members, and were exposed to smoking friends and family members were more likely to progress to established smoking at follow-up in 1996. In addition, adolescents who were receptive to advertising and believed that they could quit anytime were more likely to progress to established smoking than those who did not think they could quit anytime. Adolescents who were willing to use a promotional item and who believed that they could quit anytime had the highest rate of progression to established smoking (52%). CONCLUSIONS: This study provides evidence that receptivity to tobacco advertising and promotions is an important factor in progressing from experimentation to established smoking among adolescents. Because perceived ability to quit made adolescents more likely to progress, counter-tobacco marketing campaigns should incorporate messages about addiction and difficulties associated with quitting.

African American smokers interested and eligible for a smoking cessation clinical trial: predictors of not returning for randomization.

PURPOSE: Recruitment is often the rate-limiting step in conducting clinical trials among ethnic minorities. Little is known about participants who consent and enroll into a trial, but do not return for randomization. Why participants fail to return for randomization is largely unknown. METHODS: We compared 287 enrolled African American smokers who did not return for randomization, to the 500 who returned and were randomized to participate in a clinical trial for smoking cessation in African Americans. Analyses were conducted to identify variables associated with not returning for randomization. RESULTS: Univariate comparisons found the nonrandomized group to be significantly different from those randomized. Logistic regression showed younger age, less readiness to quit, having been proactively recruited, lacking a regular source of health care, believing that they will be smoking in 6 months, less church attendance, and a lower literacy level to be jointly related with not returning for randomization. CONCLUSIONS: African American participants who did not return for randomization into a clinical trial were different from those who did. Better understanding of these factors may allow researchers to target recruitment efforts resulting in enhanced accrual in clinical trials and increased efficiency.

Light smokers: issues and recommendations.

Although the overall prevalence of tobacco smoking in the United States is decreasing, the proportion of light smokers is increasing and is as high as 50% among some groups. There is growing evidence that light smokers experience significantly higher health risks compared to nonsmokers, and they are often unable to quit smoking on their own. The prevalence of light smoking differs among subpopulations in the US and is particularly common among adolescents, college students, pregnant women, and some ethnic minorities. Characteristics of light smokers in these subpopulations vary, as do the underlying reasons for smoking, barriers to cessation, and treatment issues. Unfortunately, the paucity of research to develop and test effective cessation aids is common across all groups of light smokers. Given the substantial portion of light smokers in these populations, development and dissemination of effective behavioral and pharmacological interventions for light smokers is likely to result in substantial smoking reduction rates in the general population.

Effect of children on home smoking restriction by inner-city smokers.

OBJECTIVE: The home is the site of the most significant environmental tobacco smoke (ETS) exposure for children. Surveys show that adults, including smokers, agree that smoking should be restricted in homes of smokers with children. However, in a national survey, only 12.5% of such homes are actually smoke-free. This study examined factors associated with home smoking restriction among inner-city smokers. METHODS: A cross-sectional survey of 598 adult smokers who attended an inner-city community health center was conducted. RESULTS: Home smoking restriction was reported by 38.2% of all smokers (95% confidence interval [CI]: 33.6%-42.8%). Univariate analysis showed smoking restriction was positively associated with presence of children and of a nonsmoking adult partner in the home, intentional limiting of smoking, stages of change, and fewer number of cigarettes smoked daily. On multivariate analysis, home smoking restriction was more likely with the presence of a child (odds ratio: 2.63; 95% CI: 1.70-4.08) and a nonsmoking adult partner (odds ratio: 2.30; 95% CI: 1.32-4.02) in the home. CONCLUSIONS: The presence of children and of nonsmoking adults is associated with the practice of smoking restriction in the homes of inner-city smokers. These findings suggest that inner-city smokers are concerned about health effects of ETS on children. Health professionals should target nonsmoking adult members of households with children and smokers but no home smoking restriction and emphasize the health effects of ETS on children as a motivation for smoking parents to limit exposure and to quit smoking.

Benefits of and barriers to providing smoking treatment in methadone clinics: findings from a national study.

Although smoking increases morbidity and mortality among patients in addictions clinics, few clinics provide routine smoking treatment. To understand staff attitudes toward treatment, we surveyed leaders of outpatient methadone treatment clinics nationwide. Our response rate was 59% (408/697). Most clinic leaders thought they should provide smoking treatment (76%) or refer patients for care (91%); however, fewer than half of these had provided treatment in the month prior to the survey. Leaders said smoking treatment would benefit their clinics, patients and communities, but said barriers-primarily insufficient staff training-prevented routine care. Addressing these barriers could increase smoking treatment in addictions clinics and save lives.
