Background: Cigarette smoking and alcohol use are well known to be concomitant behaviors, but there is a lack of studies related to recruitment of smokers for mobile cessation services at places where alcohol is consumed, such as bars and clubs. Adapting recruitment strategies to expand the reach of cessation programs to where tobacco users are located may help decrease the health-equity gap in tobacco control by improving reach and enrollment of underserved smokers residing in low-income and rural areas who are not reached by traditional cessation services.

Objective: The purpose of this exploratory study was to assess the feasibility of direct outreach in bars, clubs, and restaurants to recruit smokers to Quitxt, our mobile smoking cessation service.

Salud America! is a national network created to engage Latino researchers, health professionals and community leaders in actions to reduce Latino childhood obesity. An online survey of 148 Salud America! network members investigated relationships between (1) their levels of engagement with the network, (2) self- and collective-efficacy, and (3) behavioral intentions to engage in advocacy for policies that can help reduce Latino childhood obesity. Analyses of these data found that higher levels of Salud America! engagement was associated with collective-advocacy efficacy-greater confidence in organized group advocacy as a way of advancing policies to reduce Latino childhood obesity.

The objective of this study was to determine the value of using social media to communicate child health information to low-income parents. We evaluated qualitative data obtained through focus groups with low-income, predominantly Hispanic parents. Results were mixed; lack of time and credibility were the primary objections parents cited in using social media to obtain information about their children's health.

Introduction: Quitlines that provide telephone counseling for smoking cessation have been proved to be effective. All 50 states currently provide free quitline access to their residents; however, little research has been published on African American utilization of quitlines or their success rates.

Methods: This study evaluated how effectively African Americans are served by telephone counseling (quitline) for smoking cessation based on empirical data from 45,510 callers from Texas, Louisiana, Washington, and District of Columbia and randomized clinical trial data from 3,522 participants.

After litigation against the tobacco industry ended in a settlement, the Texas legislature funded pilot projects to reduce tobacco use in selected areas of the state. Subsequent telephone surveys showed that well-funded activities were successful in reducing population rates of self-reported cigarette smoking. We present evidence that the reduction in smoking promptly led to lower rates of death from acute myocardial infarctions.

Attitudes toward smoking, self-efficacy to avoid smoking, and smoking intention, widely cited correlates of youth smoking prevention, are often measured in large-scale youth tobacco surveys. The psychometric properties of these scales have not been well studied among middle school youth. We examined the factorial, discriminate, and convergent validity of these scales among sixth to eighth graders from a convenience sample of 22 Texas middle schools (51.

Background: Although many smokers seek Internet-based cessation assistance, few studies have experimentally evaluated long-term cessation rates among cigarette smokers who receive Internet assistance in quitting.

Objective: The purpose of this study is to describe long-term smoking cessation rates associated with 6 different Internet-based cessation services and the variation among them, to test the hypothesis that interactive and tailored Internet services yield higher long-term quit rates than more static Web-posted assistance, and to explore the possible effects of level of site utilization and a self-reported indicator of depression on long-term cessation rates.

Method: In 2004-05, a link was placed on the American Cancer Society (ACS) website for smokers who wanted help in quitting via the Internet.

Smoking-related self-efficacy and beliefs about the benefits of smoking are consistently related to intention to continue smoking, a common proximal outcome in youth smoking cessation studies. Some measures of these constructs are used frequently in national and state youth tobacco surveys, despite little evidence of validity for high school smokers. Further, the association of the constructs with intention has not been demonstrated in this group.

Because settlement proceeds allocated for tobacco control in Texas are insufficient for statewide activity at federally recommended funding levels, the Texas Department of State Health Services has used the available funds in quasi-experimental pilot studies in which varying amounts of support are provided for selected parts of the state. Trends in tobacco use were measured in telephone surveys of 7,998 (2000), 5,150 (2002), and 5,721 (2004) adults. Prevalence of cigarette smoking declined by almost one-third in the pilot area where comprehensive and sustained pilot activities to reduce tobacco use were organized at close to the federally recommended funding level.

In exploring the mechanisms of behavioral change for hypertension control, a study based on the transtheoretical model was carried out in Taiwan in 2000, with a sample of 350 hypertensive adults living in Taipei urban and rural areas. The relationships among stages of change, processes of change, and demographic factors were analyzed for six health behaviors: low-fat food consumption, alcohol use, smoking, physical activity, weight control and routine blood pressure check-ups. The results showed that rural populations had greater difficulty than urban populations in avoiding smoking and engaging in physical activity, and the processes of change being used by urban populations were significantly greater than rural populations for diet, physical activity and routine blood pressure check-up.
