Efficacy of a couple-based randomized controlled trial to help Latino fathers quit smoking during pregnancy and postpartum: the Parejas trial.

ABSTRACT: Although many Latinos in the United States smoke, they receive assistance to quit less often than non-Latinos. To address this disparity, we recruited Latino couples into a randomized controlled trial and provided a smoking cessation program during a teachable moment, when men's partners were pregnant.We compared two interventions: (i) written materials plus nicotine replacement therapy (NRT) to (ii) materials, NRT, and couple-based counseling that addressed smoking cessation and couples communication. We recruited 348 expectant fathers who smoked via their pregnant partners from county health departments. Our primary outcome was 7-day point prevalence smoking abstinence and was collected from November 2010 through April 2013 and analyzed in February 2014.We found high rates of cessation but no arm differences in smoking rates at the end of pregnancy (0.31 vs. 0.30, materials only vs. counseling, respectively) and 12 months after randomization (postpartum: 0.39 vs. 0.38). We found high quit rates among nondaily smokers but no arm differences (0.43 vs. 0.46 in pregnancy and 0.52 vs. 0.48 postpartum). Among daily smokers, we found lower quit rates with no arm differences but effects favoring the intervention arm (0.13 vs. 0.16 in pregnancy and 0.17 vs. 0.24 postpartum).A less intensive intervention promoted cessation equal to more intensive counseling. Postpartum might be a more powerful time to promote cessation among Latino men.Less intensive interventions when delivered during teachable moments for Latino men could result in a high smoking cessation rate and could reduce disparities.

Project description:BACKGROUND:The Institute for International Internet Interventions for Health at Palo Alto University proposes to develop digital tools specifically to help low-income English- and Spanish-speaking smokers to quit. Individuals from lower-income countries and those with lower social status quit at lower rates than those from high-income countries and those with higher social status. OBJECTIVE:We plan to launch a project designed to test whether a mobile-based digital intervention designed with systematic input from low-income English- and Spanish-speaking smokers from a public-sector health care system can significantly improve its acceptability, utilization, and effectiveness. METHODS:Using human-centered development methods, we will involve low-income patients in the design of a Web app/text messaging tool. We will also use their input to improve our recruitment and dissemination strategies. We will iteratively develop versions of the digital interventions informed by our human-centered approach. The project involves three specific aims: (1) human-centered development of an English/Spanish smoking cessation web app, (2) improvement of dissemination strategies, and (3) evaluation of resulting smoking cessation web app. We will develop iterative versions of a digital smoking cessation tool that is highly responsive to the needs and preferences of the users. Input from participants will identify effective ways of reaching and encouraging low-income English- and Spanish-speaking smokers to use the digital smoking cessation interventions to be developed. This information will support ongoing dissemination and implementation efforts beyond the grant period. We will evaluate the effectiveness of the successive versions of the resulting stop smoking Web app by an online randomized controlled trial. Increased effectiveness will be defined as increased utilization of the Web app and higher abstinence rates than those obtained by a baseline usual care Web app. RESULTS:Recruitment will begin January 2016, the study is intended to be completed by summer 2018, and the results should be available by fall 2019. CONCLUSIONS:This study will provide useful knowledge in developing, testing, and disseminating mobile-based interventions for low-income smokers.

Project description:BackgroundEarly in medical education, physicians must develop competencies needed for tobacco dependence treatment.ObjectiveTo assess the effect of a multi-modal tobacco dependence treatment curriculum on medical students' counseling skills.DesignA group-randomized controlled trial (2010-2014) included ten U.S. medical schools that were randomized to receive either multi-modal tobacco treatment education (MME) or traditional tobacco treatment education (TE).Setting/participantsStudents from the classes of 2012 and 2014 at ten medical schools participated. Students from the class of 2012 (N = 1345) completed objective structured clinical examinations (OSCEs), and 50 % (N = 660) were randomly selected for pre-intervention evaluation. A total of 72.9 % of eligible students (N = 1096) from the class of 2014 completed an OSCE and 69.7 % (N = 1047) completed pre and post surveys.InterventionsThe MME included a Web-based course, a role-play classroom demonstration, and a clerkship booster session. Clerkship preceptors in MME schools participated in an academic detailing module and were encouraged to be role models for third-year students.MeasurementsThe primary outcome was student tobacco treatment skills using the 5As measured by an objective structured clinical examination (OSCE) scored on a 33-item behavior checklist. Secondary outcomes were student self-reported skills for performing 5As and pharmacotherapy counseling.ResultsAlthough the difference was not statistically significant, MME students completed more tobacco counseling behaviors on the OSCE checklist (mean 8.7 [SE 0.6] vs. mean 8.0 [SE 0.6], p = 0.52) than TE students. Several of the individual Assist and Arrange items were significantly more likely to have been completed by MME students, including suggesting behavioral strategies (11.8 % vs. 4.5 %, p < 0.001) and providing information regarding quitline (21.0 % vs. 3.8 %, p < 0.001). MME students reported higher self-efficacy for Assist, Arrange, and Pharmacotherapy counseling items (ps ≤0.05).LimitationsInclusion of only ten schools limits generalizability.ConclusionsSubsequent interventions should incorporate lessons learned from this first randomized controlled trial of a multi-modal longitudinal tobacco treatment curriculum in multiple U.S. medical schools.

Project description:ImportanceMost women who quit smoking during pregnancy will relapse postpartum. Previous efforts to prevent postpartum relapse have been unsuccessful at increasing rates of sustained abstinence.ObjectiveTo evaluate the relative efficacy of 2 different approaches to prevent postpartum smoking relapse.Design, setting, and participantsPregnant women who recently had quit smoking were recruited before the end of pregnancy. Intervention sessions were conducted through a combination of telephone calls and in-person visits beginning at delivery and continuing through 24 weeks postpartum. Participants completed assessments at the prenatal baseline and at 12, 24, and 52 weeks postpartum. Participants were recruited between March 2008 and December 2012. The dates of the analysis were April 2014 to February 2015.InterventionsWomen received postpartum-adapted, behavioral smoking relapse prevention intervention and were randomly assigned to an enhanced cognitive behavioral intervention that included additional specialized strategies and content focused on women's postpartum concerns about mood, stress, and weight (Strategies to Avoid Returning to Smoking [STARTS]) or a supportive, time and attention-controlled comparison (SUPPORT). Intervention began before delivery and continued through 24 weeks postpartum.Main outcomes and measuresThe primary outcome was biochemically confirmed sustained tobacco abstinence at 52 weeks postpartum. Secondary outcomes were self-reported mood, levels of perceived stress, and degree of concern about smoking-related weight gain.ResultsThe study cohort comprised 300 participants (150 randomly assigned to each group). Their mean (SD) age was 24.99 (5.65) years. Overall, 38.0% (114 of 300), 33.7% (101 of 300), and 24.0% (72 of 300) of the sample maintained abstinence at 12, 24, and 52 weeks' postpartum, respectively. There were no differences between the intervention groups in abstinence or time to relapse. Self-reported depressive symptoms and perceived stress significantly improved over time, and improvements were similar for both intervention groups. Women with more depressive symptoms and higher levels of perceived stress were more likely to relapse (hazard ratio, 1.02; 95% CI, 1.00-1.04; P = .04 for depressive symptoms and hazard ratio, 1.04; 95% CI, 1.01-1.07; P = .003 for stress).Conclusions and relevanceAn intervention designed to address women's concerns about mood, stress, and weight did not differentially improve rates of sustained tobacco abstinence postpartum compared with a time and attention-controlled comparison. Women in STARTS and SUPPORT reported postpartum improvements in mood and stress, and the experience of fewer depressive symptoms and less perceived stress was related to sustained abstinence. Given that most pregnant quitters will relapse within 1 year postpartum and that postpartum smoking has negative health consequences for women and children, effective interventions that target postpartum mood and stress are needed.Trial registrationclinicaltrials.gov Identifier: NCT00757068.
