ABSTRACT AIMS: To assess the effects of adding motivational interviewing (MI) counseling to nicotine patch for smoking cessation among homeless smokers. DESIGN: Two-group randomized controlled trial with 26-week follow-up. PARTICIPANTS AND SETTING: A total of 430 homeless smokers from emergency shelters and transitional housing units in Minneapolis/St Paul, Minnesota, USA. INTERVENTION AND MEASUREMENTS: All participants received 8-week treatment of 21-mg nicotine patch. In addition, participants in the intervention group received six individual sessions of MI counseling which aimed to increase adherence to nicotine patches and to motivate cessation. Participants in the standard care control group received one session of brief advice to quit smoking. Primary outcome was 7-day abstinence from cigarette smoking at 26 weeks, as validated by exhaled carbon monoxide and salivary cotinine. FINDINGS: Using intention-to-treat analysis, verified 7-day abstinence rate at week 26 for the intervention group was non-significantly higher than for the control group (9.3% versus 5.6%, P = 0.15). Among participants who did not quit smoking, reduction in number of cigarettes from baseline to week 26 was equally high in both study groups (-13.7 ± 11.9 for MI versus -13.5 ± 16.2 for standard care). CONCLUSIONS: Adding motivational interviewing counseling to nicotine patch did not increase smoking rate significantly at 26-week follow-up for homeless smokers.

    ABSTRACT: To conduct a systematic review and meta-analysis examining the effectiveness of behavioural interventions targeting diet, physical activity or smoking in low-income adults. Systematic review with random effects meta-analyses. Studies before 2006 were identified from a previously published systematic review (searching 1995-2006) with similar but broader inclusion criteria (including non-randomised controlled trials (RCTs)). Studies from 2006 to 2014 were identified from eight electronic databases using a similar search strategy. MEDLINE, EMBASE, PsycINFO, ASSIA, CINAHL, Cochrane Controlled Trials, Cochrane Systematic Review and DARE. RCTs and cluster RCTs published from 1995 to 2014; interventions targeting dietary, physical activity and smoking; low-income adults; reporting of behavioural outcomes. Dietary, physical activity and smoking cessation behaviours. 35 studies containing 45 interventions with 17 000 participants met inclusion criteria. At postintervention, effects were positive but small for diet (standardised mean difference (SMD) 0.22, 95% CI 0.14 to 0.29), physical activity (SMD 0.21, 95% CI 0.06 to 0.36) and smoking (relative risk (RR) of 1.59, 95% CI 1.34 to 1.89). Studies reporting follow-up results suggested that effects were maintained over time for diet (SMD 0.16, 95% CI 0.08 to 0.25) but not physical activity (SMD 0.17, 95% CI -0.02 to 0.37) or smoking (RR 1.11, 95% CI 0.93 to 1.34). Behaviour change interventions for low-income groups had small positive effects on healthy eating, physical activity and smoking. Further work is needed to improve the effectiveness of behaviour change interventions for deprived populations. Published by the BMJ Publishing Group Limited.

    ABSTRACT: Background and AimsSmoking prevalence among homeless adults is exceedingly high, and high rates of comorbid substance use are among the barriers to abstinence experienced by this group. The extent to which smoking cessation might engender an escalation in comorbid substance use could be a concern prohibiting treatment provision and engagement. This study examined whether smoking abstinence status was associated with alcohol and substance use at 26 weeks post-randomization among homeless smokers in a smoking cessation trial.DesignThe current study was a secondary analysis of randomized smoking cessation intervention trial data.SettingThe parent study was conducted in the Minneapolis/St. Paul area of Minnesota, USA.ParticipantsParticipants were 427 homeless adult smokers interested in quitting smoking.MeasurementsCovariates collected at baseline included alcohol, cocaine, marijuana/hashish, heroin, and “any” drug use, age, sex, race/ethnicity, education, tobacco dependence, length of time homeless, and treatment group. Biochemically-verified smoking abstinence and self-reported alcohol and substance use were collected at 26 weeks post-randomization.FindingsSmoking abstinence was associated with fewer drinking days (p=.03), fewer drinks consumed on drinking days (p=.01), and lower odds of heavy drinking (p=.05), but not with differences in the number of days of cocaine, marijuana/hashish, heroin, or any drug use.Conclusions In homeless smokers, achieving smoking abstinence may be associated with a reduction in alcohol consumption but appears not to be associated with a substantial change in other drug use.
