Why girls smoke: a proposed community-based prevention program

Comparison of media literacy and usual education to prevent tobacco use: a cluster-randomized trial

BACKGROUND

Media literacy programs have shown potential for reduction of adolescent tobacco use. We aimed to determine if an anti-smoking media literacy curriculum improves students' media literacy and affects factors related to adolescent smoking.

METHODS

We recruited 1170 9th-grade students from 64 classrooms in 3 public urban high schools. Students were randomized by classroom to a media literacy curriculum versus a standard educational program. In an intent-to-treat analysis, we used multilevel modeling to determine if changes in study outcomes were associated with the curricular intervention, controlling for baseline student covariates and the clustering of students within classrooms.

RESULTS

Among participants, mean age was 14.5 years and 51% were male, with no significant differences in baseline characteristics between groups. Smoking media literacy changed more among intervention participants compared with control participants (0.24 vs. 0.08, p < .001). Compared with controls, intervention students exhibited a greater reduction in the perceived prevalence of smoking (-14.0% vs. -4.6%, p < .001). Among those initially susceptible to smoking, intervention participants more commonly reverted to being nonsusceptible post-intervention (24% vs. 16%, p = .08).

CONCLUSIONS

A school-based media literacy curriculum is more effective than a standard educational program in teaching media literacy and improving perceptions of the true prevalence of smoking among adolescents.

Testing the theory of reasoned action in explaining sexual behavior among African American young teen girls

This study tested the Theory of Reasoned Action to examine the prediction of early sexual behavior among African American young teen girls. Baseline data from a longitudinal randomized clinical trial were used. Between 2001 and 2005, 198 middle-school girls aged 11 to 14 years were recruited. As girls aged, they held more permissive attitudes toward engaging in early sexual behavior and had a higher intention to engage in early sexual behavior. Intention was a significant predictor to explain sexual behavior among the girls. There is a need to develop strategies that promote intention related to delay and prevention of early sexual behavior.

Associations between smoking and media literacy in college students

Organizations recommend media literacy to reduce tobacco use, and higher media literacy has been associated with lower smoking among high school students. The relationship between smoking media literacy and tobacco use, however, has not been systematically studied among college students. The purpose of this study was to determine the association between smoking and smoking media literacy among college students. We conducted the National College Health Assessment (NCHA) at a large, urban university, adding six items measuring smoking media literacy. A total of 657 students responded to this random sample e-mail survey. We used multiple logistic regression to determine independent associations between smoking media literacy items and current smoking. The media literacy scale was internally consistent (alpha = 0.79). Of the respondents, 21.5% reported smoking cigarettes over the past 30 days. In a fully adjusted multivariate model, participants with medium media literacy had an odds ratio (OR) for current smoking of 0.45 (95% CI = 0.29, 0.70), and those with high media literacy had an OR for current smoking of 0.38 (95% CI = 0.20, 0.70). High smoking media literacy is independently associated with lower odds of smoking. Smoking media literacy may be a valuable construct to address in college populations.

Salient environmental and perceptual correlates of current and established smoking for 2 representative cohorts of Indiana adolescents

PURPOSE

A secondary analysis of 2000 and 2004 Indiana Youth Tobacco Survey (IYTS) data was conducted to investigate salient environmental and perceptual correlates of adolescents' current and established smoking while controlling for demographic variables such as gender, grade, and race/ethnicity and to compare the pattern of significant correlates between the years.

METHODS

The IYTS was an anonymous school-based survey regarding tobacco use; familiarity with pro- and anti-tobacco media messages; exposure to environmental tobacco smoke (ETS); minors' access to tobacco products; and general knowledge, attitudes, and beliefs about tobacco. In 2000, a representative sample of 1416 public high school students in grades 9-12 and 1516 public middle school students in grades 6-8 (71.44% and 72.53% response rates, respectively) were surveyed. In 2004, 3433 public high school students and 1990 public middle school students (63.04% and 65.44 % response rates, respectively) were surveyed.

RESULTS

Significant predictors of adolescents' current and established smoking habits included exposure to ETS either in homes or in cars, exposure to pro-tobacco messages, perceived benefit of smoking, and perceived peer acceptance of smoking. The influence of exposure to pro-tobacco messages greatly outweighed exposure to any anti-tobacco messages.

CONCLUSIONS

The findings of this study warrant that more efforts and resources be placed on preventing youth from being exposed to ETS, and to control pro-tobacco marketing and improve the tobacco counter-marketing messages. The perceived benefits of smoking found here indicate that smoking for relaxation and weight control may be major influencing factors on adolescent smoking.

Proscriptive models and evidence in antismoking advertising

This study assessed the proscriptive models and evidence used in antismoking campaigns. A content analysis of 399 television advertisements cataloged in the Media Campaign Resource Center database was conducted. Findings reveal that the analyzed advertisements fail to use evidence and often reinforce proscriptive models of smoking. In advertisements with images of a smoker (N = 111), 40% showed no graphic visual consequences from smoking, and 2% portrayed the smoker as someone engaged in vigorous activities. In 20% of the advertisements, smoking was portrayed as a rite of passage to adulthood. Most of the advertisements did not provide any evidence to support the claims made, and advertisements aimed at teenagers were significantly less likely to use evidence than were advertisements aimed at adults (p < .01). The research identifies several areas of improvement for antismoking campaigns.

Original: anti-smoking media campaign messages: theory and practice

This study examined televised anti-smoking advertisements that were designed to discourage adult and teen smoking. A content analysis of 399 television advertisements catalogued in the Media Campaign Resource Center (MCRC) database were evaluated to determine (a) whether the advertising content reflected core health communication theories used in the design of health campaign messages to change behavior and (b) the affective presentation of tobacco-control advertisements aimed to decrease smoking. The results revealed that anti-smoking advertising relied overwhelmingly on appeals to attitudes. Although the benefits of not smoking were mentioned in 61% of advertisements, barriers were mentioned in only 17% of advertisements. Advertisements emphasized the consequences of smoking more than the viewer's self-efficacy. Finally, advertisements were more likely to use informational and humor appeals, rather than sadness, fear, or anger appeals. The research identifies the types of advertisements that are most likely to be utilized and underutilized in national and statewide anti-smoking advertising campaigns catalogued in the MCRC database.

Prevention of tobacco use in adolescents: review of current findings and implications for healthcare providers

This paper reviews recent research on adolescent smoking initiation and youth tobacco prevention and control strategies. Gender, ethnicity, family factors, and genetics are associated with smoking initiation and adolescent tobacco use. Evidence indicates that comprehensive tobacco control programs are an effective strategy for reducing adolescent smoking, and even modest gains from prevention and cessation efforts could lead to substantial reductions in the morbidity and mortality costs of smoking. Clinicians have an important role in prevention and treatment of tobacco use in adolescents, and the rate of delivery of clinical preventive services in this area should be increased. Consequently, clinicians working with adolescents should be familiar with established guidelines regarding tobacco use prevention and treatment and use general outpatient office visits as an important opportunity to prevent tobacco use.
