ABSTRACT Abstract Purpose . To evaluate the effectiveness of a cognitive behavioral treatment (CBT) addressing cessation-related weight concerns delivered via a tobacco quitline that does not address weight concerns. Design . Randomized controlled trial, blinded 6-month follow-up. Setting . The Oklahoma Tobacco Helpline (OKHL). Subjects . All 7998 smokers who called the OKHL were screened; 4240 were eligible; 2000 were randomized to the standard quitline (STD) or the brief version of the CBT weight concerns program (WCP). Intervention . Telephone counseling to help people quit smoking and address concerns about cessation-related weight gain. Measures . Demographics, weight, tobacco status, weight concerns, self-efficacy in quitting, and quitting without weight gain. Analysis . Descriptive statistics and logistic regression. Results . Of those randomized, 1002 participants completed the 6-month survey (response rates  =  53.2% for STD, 47% for WCP). Compared with STD, WCP led to reduced weight concerns (p < .01) and less weight gain among quitters (1.8 vs. -3.4 pounds; p  =  .01). Although not significant, participants in the WCP were more likely to report 30-day abstinence (33.3% vs. 36.8%, p  =  .24; intent to treat  =  17.7 vs. 17.3). Conclusion . The WCP was successfully delivered via a quitline and resulted in improved attitudes about weight and decreased cessation-related weight gain without harming quit rates. Promotion of a quitline focused on addressing weight in conjunction with quitline treatment for smoking cessation may improve cessation and weight outcomes. Study limitations include use of self-report and survey response.

    • "Several studies indicate that weight management education only is not effective in preventing post-cessation weight gain and may have the effect of reducing abstinence [2] [5] [6]. In addition, while personalized weight management support seems to be effective without affecting abstinence rates, the evidence is not definitive [6]. "

    ABSTRACT: Health interventions aimed at smoking cessation can clearly have a significant impact on public health around the globe. Even though the health benefits of quitting smoking are indisputable, research indicates that smoking cessation is associated with an increase in the prevalence of overweight. In this scenario, the present study evaluated the weight gain among patients participating in a smoking cessation intervention in order to find possible predictor variables.

    ABSTRACT: Introduction: Substantial evidence suggests that concerns about postcessation weight gain interfere with cessation efforts. However, it is unclear to what extent weight pretreatment affects smoking-related weight concerns. Given that the prevalence of overweight and obesity among callers to tobacco quitlines mirrors that of the population at large, and that women and obese smokers may be more concerned about weight gain, we sought to compare weight gain concerns among normal weight, overweight, and obese callers to a quitline. Methods: A sample of 34.6% (n = 206) normal weight, 30.6% (n = 182) overweight, and 34.8% (n = 207) obese quitline callers completed assessments of tobacco use history and smoking-specific weight concerns. Weight categories were compared and gender differences evaluated. Results: Obese smokers endorsed significantly more concerns about postcessation weight gain [F(2, 592) = 20.35, p < .0001], had less confidence in their ability to maintain their weight without smoking [F(2, 592) = 7.67, p = .0005], and were willing to tolerate less weight gain after quitting than normal weight or overweight smokers [F(2,574) = 30.59, p < .0001). There also were gender differences in weight concerns by weight status. Significantly more women callers were obese (38.2% vs. 28.4%, p = .011), and women consistently endorsed more concern about postcessation weight gain than did men [F(1,588) = 24.04, p < .0001). Conclusions: Overweight and obese smokers, particularly women, express substantial concern about gaining weight after quitting. It is possible that smokers who begin quitline treatment with a BMI in the obese range may benefit from adjunctive interventions designed to address smoking-related weight concerns.

    ABSTRACT: Telephone services can provide information and support for smokers. Counselling may be provided proactively or offered reactively to callers to smoking cessation helplines. To evaluate the effect of proactive and reactive telephone support via helplines and in other settings to help smokers quit. We searched the Cochrane Tobacco Addiction Group Specialised Register for studies of telephone counselling, using search terms including 'hotlines' or 'quitline' or 'helpline'. Date of the most recent search: May 2013. randomized or quasi-randomised controlled trials in which proactive or reactive telephone counselling to assist smoking cessation was offered to smokers or recent quitters. One author identified and data extracted trials, and a second author checked them. The main outcome measure was the risk ratio for abstinence from smoking after at least six months follow-up. We selected the strictest measure of abstinence, using biochemically validated rates where available. We considered participants lost to follow-up to be continuing smokers. Where trials had more than one arm with a less intensive intervention we used only the most similar intervention without the telephone component as the control group in the primary analysis. We assessed statistical heterogeneity amongst subgroups of clinically comparable studies using the I² statistic. We considered trials recruiting callers to quitlines separately from studies recruiting in other settings. Where appropriate, we pooled studies using a fixed-effect model. We used a meta-regression to investigate the effect of differences in planned number of calls, selection for motivation, and the nature of the control condition (self help only, minimal intervention, pharmacotherapy) in the group of studies recruiting in non-quitline settings. Seventy-seven trials met the inclusion criteria. Some trials were judged to be at risk of bias in some domains but overall we did not judge the results to be at high risk of bias. Among smokers who contacted helplines, quit rates were higher for groups randomized to receive multiple sessions of proactive counselling (nine studies, > 24,000 participants, risk ratio (RR) for cessation at longest follow-up 1.37, 95% confidence interval (CI) 1.26 to 1.50). There was mixed evidence about whether increasing the number of calls altered quit rates but most trials used more than two calls. Three studies comparing different counselling approaches during a single quitline contact did not detect significant differences. Of three studies that tested the provision of access to a hotline two detected a significant benefit and one did not.Telephone counselling not initiated by calls to helplines also increased quitting (51 studies, > 30,000 participants, RR 1.27; 95% CI 1.20 to 1.36). In a meta-regression controlling for other factors the effect was estimated to be slightly larger if more calls were offered, and in trials that specifically recruited smokers motivated to try to quit. The relative extra benefit of counselling was smaller when it was provided in addition to pharmacotherapy (usually nicotine replacement therapy) than when the control group only received self-help material or a brief intervention.A further eight studies were too diverse to contribute to meta-analyses and are discussed separately. Two compared different intensities of counselling, both of which detected a dose response; one of these detected a benefit of multiple counselling sessions over a single call for people prescribed bupropion. The others tested a variety of interventions largely involving offering telephone counselling as part of a referral or systems change and none detected evidence of effect. Proactive telephone counselling aids smokers who seek help from quitlines. Telephone quitlines provide an important route of access to support for smokers, and call-back counselling enhances their usefulness. There is limited evidence about the optimal number of calls. Proactive telephone counselling also helps people who receive it in other settings. There is some evidence of a dose response; one or two brief calls are less likely to provide a measurable benefit. Three or more calls increase the chances of quitting compared to a minimal intervention such as providing standard self-help materials, or brief advice, or compared to pharmacotherapy alone.
