Psychiatric diagnoses among quitters versus continuing smokers 3 years after their quit day.

ABSTRACT: People with psychiatric disorders are more likely to smoke and smoke more heavily than the general population, and they suffer disproportionally from smoking-related illnesses. However, little is known about how quitting versus continuing to smoke affects mental health and the likelihood of developing a psychiatric diagnosis. This study used data from a large prospective clinical trial to examine the relations of smoking cessation success with psychiatric diagnoses 1 and 3 years after the target quit day.This study enrolled 1504 smokers (83.9% white; 58.2% female) in a cessation trial that involved the completion of the Composite International Diagnostic Interview to assess psychiatric diagnoses and biochemical confirmation of point-prevalence abstinence at Baseline and Years 1 and 3.Regression analyses showed that, after controlling for pre-quit (past-year) diagnoses, participants who were smoking at the Year 3 follow-up were more likely to have developed and maintained a substance use or major depressive disorder by that time than were individuals who were abstinent at Year 3.Quitting smoking does not appear to negatively influence mental health in the long-term and may be protective with respect to depression and substance use diagnoses; this should encourage smokers to make quit attempts and encourage clinicians to provide cessation treatment.

Project description:IntroductionMost smoking cessation approaches are modeled on heavy daily smoking. With increasing prevalence of nondaily smoking, it may be necessary to modify these approaches for nondaily smokers.AimsTo provide information about beliefs and attitudes relevant to smoking cessation for nondaily smokers.MethodsSecondary analysis of two prospective studies on young adult smokers (18-24 years of age) provided brief advice to quit smoking. Measures include baseline levels of constructs relevant to smoking cessation counseling and perceived benefits of and barriers to smoking cessation.ResultsParticipants (n = 40 nondaily, 122 daily smokers) were predominantly White (70% and 84%, respectively), gender-balanced (50% and 43% female), full-time college students (89% and 95%). At baseline, nondaily smokers reported lower levels of nicotine dependence (p < .001; nondaily: Fagerström Test for Nicotine Dependence (FTND) = 0.8 ± 1.5, daily: FTND = 3.1 ± 1.9), lower urge to smoke (p < .001), greater self-efficacy when facing external smoking stimuli (p = .03), expecting to experience fewer positive effects (reduced negative affect, p = <.001, stimulation, p = .02), and valuing the importance of smoking effects less (ps < .01) than daily smokers. During counseling, nondaily smokers generated both fewer benefits of cessation (Wald X2(df = 1) = 4.91, p = .027) and fewer barriers (Wald X2(df = 1) = 5.99, p =.014) than daily smokers. Withdrawal was not listed by nondaily smokers as a barrier (p < .01).ConclusionsConstructs relevant to smoking cessation for daily smokers were less salient to young nondaily smokers, compared with moderately addicted young daily smokers, as indicated by responses to standardized scales and by the generation of fewer benefits and barriers in counseling. Interventions may need to find novel ways to engage nondaily smokers, particularly young adult, in smoking cessation efforts.ImplicationsThis study is unique in eliciting benefits and barriers from nondaily smokers as they are about to make a quit attempt. This is a critically important point in time, as this is the point in time in which an action plan is formed and can be informed and enhanced by smoking cessation support. Our study further allowed direct comparison to daily smokers undergoing the same procedures, which allowed the identification of unique factors that may impact nondaily smokers in their quit attempt, which may guide intervention efforts. Use of a mixed method design further strengthen the rigor of this study.

Project description:AimsLittle is known about the extent to which quit attempts are planned ahead or initiated immediately following a sudden decision to quit. This is important because if most smokers quit abruptly, rather than plan ahead, this could impact heavily upon recommendations to health care professionals on the kind of smoking cessation advice they deliver to patients. This paper aims to address this gap in knowledge by examining detailed smoking histories taken from smoking and ex-smoking patients.DesignFace-to-face in depth semi-structured interviews.Participants146 smoking and ex-smoking patients within a family medicine practice were recruited by means of screening 700 consecutive patients (14 years of age and older) and inviting eligible patients to participate. To be eligible, patients had to have smoked a minimum of five cigarettes per day for at least six months in their lives and made at least one serious quit attempt that lasted at least 24 hours. There were no refusals. Ex-smokers (n = 67) were defined as those who had not smoked for six months. The remainder were classified as smokers (n = 79).MeasurementsParticipants were asked to describe, in their own words, their most recent quit attempt and whether they had planned the quit attempt in advance, what were the triggers, and how long they abstained. A quit attempt was defined as planned if smokers set a quit date at some future time point. An unplanned quit attempt was defined as a sudden decision not to smoke any more cigarettes including those that might be remaining in the current pack. Information was also collected on methods used to quit and reasons for quitting.ResultsA majority (51.6%) of quit attempts were reported as being unplanned. The figure was higher for ex-smokers than for smokers (67.1% v 36.7%, p < 0.001). Most quit attempts were unaided (64%) and made for reasons of health (64%).ConclusionsThe finding that so many quit attempts are unprepared suggests that models of smoking cessation should place greater emphasis on the dynamic nature of motivation to quit. This is an area that requires further investigation.

Project description:Many smokers find the cost of smoking cessation medications a barrier. Financial coverage for these medications increases utilization of pharmacotherapies. This study assesses whether financial coverage increases the proportion of successful quitters.A pragmatic, open-label, randomized, controlled trial was conducted in 58 Canadian sites between March 2009 and September 2010. Smokers (?10 cigarettes/day) without insurance coverage who were motivated to quit within 14 days were randomized (1:1) in a blinded manner to receive either full coverage eligibility for 26 weeks or no coverage. Pharmacotherapies covered were varenicline, bupropion, or nicotine patches/gum. Investigators/subjects were unblinded to study group assignment after randomization and prior to choosing a smoking cessation method(s). All subjects received brief smoking cessation counseling. The primary outcome measure was self-reported 7-day point prevalence of abstinence (PPA) at week 26.Of the 1380 randomized subjects (coverage, 696; no coverage, 684), 682 (98.0%) and 435 (63.6%), respectively, were dispensed at least one smoking cessation medication dose. The 7-day PPA at week 26 was higher in the full coverage versus no coverage group: 20.8% (n?=?145) and 13.9% (n?=?95), respectively; odds ratio (OR)?=?1.64, 95% confidence interval (CI) 1.23-2.18; p?=?0.001. Urine cotinine-confirmed 7-day PPA at week 26 was 15.7% (n?=?109) and 10.1% (n?=?69), respectively; OR?=?1.68, 95% CI 1.21-2.33; p?=?0.002. After pharmacotherapy, coverage eligibility was withdrawn from the full coverage group, continuous abstinence between weeks 26 and 52 was 6.6% (n?=?46) and 5.6% (n?=?38), in the full coverage and no coverage groups, respectively; OR?=?1.19, 95% CI 0.76-1.87; p?=?0.439.In this study, the adoption of a smoking cessation medication coverage drug policy was an effective intervention to improve 26-week quit rates in Canada. The advantages were lost once coverage was discontinued. Further study is required on the duration of coverage to prevent relapse to smoking.
