Preferences for mobile-supported e-cigarette cessation interventions among young adults: A qualitative descriptive study (Preprint)

BACKGROUND Despite the steady rise in e-cigarette uptake among young adults, increasingly more young people want to quit. Given the popularity of smartphones among young adults, mobile-based e-cigarette cessation interventions hold significant promise. Smartphone apps are particularly promising due to their varied and complex capabilities to engage and end-user. However, evidence around young adults’ preferences and expectations from an e-cigarette cessation smartphone app remains unexplored. OBJECTIVE The purpose of this study was to take an initial step towards understanding young adults' preferences and perceptions on app-based e-cigarette cessation interventions. METHODS Using a qualitative descriptive approach, we interviewed 12 young adults who used e-cigarettes and wanted to quit. We inductively derived themes using the framework analysis approach and NVivo 12 qualitative data analysis software. RESULTS All participants agreed that a smartphone app for supporting cessation was desirable. In addition, we found 4 key themes related to their preferences for an app: (1) flexible personalization (2) e-cigarette behavior tracking, (3) safely managed social support, and (4) positive-framed notifications. CONCLUSIONS The findings provide direction for the development and testing of app-based e-cigarette cessation interventions for young adults.

Effectiveness of ENDS, NRT and medication for smoking cessation among cigarette-only users: a longitudinal analysis of PATH Study wave 3 (2015–2016) and 4 (2016–2017), adult data

BackgroundResearch is inconclusive on the effectiveness of electronic nicotine delivery systems (ENDS) as cigarette cessation aids compared with nicotine replacement therapy (NRT) or non-NRT medication. This study compared the cigarette cessation rates for ENDS, NRT and non-NRT medication.MethodPopulation Assessment of Tobacco and Health Study wave 3 cigarette-only users who used ENDS, NRT or non-NRT medication (varenicline and bupropion) to quit smoking between wave 3 and 4 were included. ‘Cessation’ was defined as being a former cigarette smoker in wave 4. χ2, logistic regression, and a sensitivity analysis with Bayes factor assessed the association between quitting smoking and method used.ResultsAmong 6794 cigarette-only users, 532 used ENDS (n=75), NRT (n=289), non-NRT medication (n=68), or a combination of NRT and non-NRT medication (n=100) to quit smoking between wave 3 and 4. The percentages of quitting smoking among those who used ENDS, NRT, non-NRT medication, and a combination of NRT and non-NRT medication were 16.2% (n=14), 16.1% (n=47), 17.7% (n=13), and 14.8% (n=12), respectively (p=0.97). None of the cigarette-only users who used ENDS to quit smoking became ENDS-only users in wave 4; 37.6% became dual users of ENDS and cigarettes.ConclusionNo differences were found when cessation rates of ENDS, NRT or non-NRT medication were compared. Given uncertainty about the long-term health effect of ENDS and the likelihood of becoming dual users, people who smoke and need assistance quitting should be encouraged to use current Food and Drug Administration-approved cessation methods until more effective methods are developed.

Smoking cessation in Brazil: a survival analysis based on consumers’ profile

Cigarette consumption is a worldwide epidemic and its reduction is one of the major public health concerns. In Brazil, although there is a wide literature on smoking cessation it is restricted to experimental studies. Based on data from the 2013 National Health Survey (PNS), this study uses the survival methodology and use population data and consumer’s profile to investigate which characteristics will affect smoking cessation hazard. The results showed that the people who are less likely to quit smoking are older, single men, with low income and fewer education years. They also do not practice physical exercise. The findings of cigarette cessation hazard to Brazilian population are similar of experimental studies with smokers and ex-smokers in country. Therefore, in order to decrease public health spending, Brazilian health policies regarding tobacco cessation could focus on those groups who will likely smoke for a long time.
