IntroductionHeated tobacco products (HTPs) are increasingly popular worldwide, but whether they aid or undermine cigarette abstinence remains uncertain. We examined the predictors of HTP initiation and the prospective association of HTP use with cigarette abstinence in community-based smokers in Hong Kong.DesignSecondary analysis of a randomised clinical trial aimed to evaluate the effectiveness of brief advice and referral for smoking cessation. The interventions were not related to HTP use.Participants and settings1213 carbon monoxide-verified daily cigarette smokers with intentions to quit or reduce smoking proactively recruited from community sites throughout Hong KongMain exposureCurrent (past 7 day) use of HTP at baseline.Main outcomeSelf-reported 7-day point-prevalence cigarette abstinence at 6 months (exclusive use of HTP permitted).ResultsAt baseline, 201 (16.6%) and 60 (4.9%) were ever and current HTP users, respectively. During the 6-month follow-up period, 110 of 1012 (10.9%) never users at baseline initiated HTPs. Younger age and higher education significantly predicted initiation. After adjusting for sociodemographic, smoking-related and quitting-related factors, current HTP use at baseline was not associated with cigarette abstinence at 6 months (adjusted prevalence ratio (aPR) 1.08, 95% CI 0.63 to 1.85). The results were similar in persistent users from baseline to 1-month/3-month follow-up (vs non-users; aPR 1.14, 95% CI 0.57 to 2.29). Use of smoking cessation service between baseline and 3-month follow-up significantly predicted cigarette abstinence (aPR 1.70, 95% CI 1.26 to 2.30).ConclusionHTP use was not associated with cigarette abstinence at 6 months in a community-based cohort of smokers with intentions to quit or reduce smoking.Trial registration detailsClinicalTrials.gov, NCT03565796.

Objectives: In this study, we tested the use of ecigarette, cigarette, and dual use of both as predictors of heat-not-burn (HNB) tobacco product use onset among young adults, and examined common predictors of smoking cessation as predictors of HNB product use. Methods: We collected data from 2229 young adults [mean age = 21.1 (SD = 2.1); 55% women] in Hawaii, at 2 time-points 6 months apart. Results: Current cigarette-only use was the strongest concurrent predictor of HNB product use, followed by dual use, and ecigarette-only use. Among HNB product never users at Wave 1, dual and ecigarette-only use at Wave 1 significantly predicted HNB product use onset at Wave 2. Among cigarette smokers who had never used an HNB product at Wave 1, current use of ecigarette for help with smoking cessation predicted increased odds of HNB product use at 6-month follow-up. Conclusions: Although promoted as a safer alternative for exclusive cigarette smokers, HNB products may increase the risk of dual or poly-tobacco product use among young adults, including current exclusive e-cigarette users. Surveillance of HNB product use as a modified risk tobacco product may need to consider the effects of HNB products on poly-tobacco use among young people.

Abstract Aims Most cigarette smokers want to quit smoking and more than half make an attempt every year, but less than 10% remain abstinent for at least 6 months. Evidence-based tobacco use treatment improves the likelihood of quitting, but more than two-thirds of individuals relapse when provided even the most robust treatments. Identifying for whom treatment is effective will improve the success of our treatments and perhaps identify strategies for improving current approaches. Methods Two cohorts (training: N = 90, validation: N = 71) of cigarette smokers enrolled in group cognitive-behavioral therapy (CBT). Generalized estimating equations were used to identify baseline predictors of outcome, as defined by breath carbon monoxide and urine cotinine. Significant measures were entered as candidate variables to predict quit status. The resulting decision trees were used to predict cessation outcomes in a validation cohort. Results In the training cohort, the decision trees significantly improved on chance classification of smoking status following treatment and at 6-month follow-up. The first split of all decision trees, which was delay discounting, significantly improved on chance classification rates in both the training and validation cohort. Delay discounting emerged as the single best predictor of group CBT treatment response with an average baseline discount rate of ln(k) = −7.1, correctly predicting smoking status of 80% of participants at posttreatment and 81% of participants at follow-up. Conclusions This study provides a first step toward personalized care for smoking cessation though future work is needed to identify individuals that are likely to be successful in treatments beyond group CBT. Implications This study provides a first step toward personalized care for smoking cessation. Using a novel machine-learning approach, baseline measures of clinical and executive functioning are used to predict smoking cessation outcomes following group CBT. A decision point is recommended for the single best predictor of treatment outcomes, delay discounting, to inform future research or clinical practice in an effort to better allocate patients to treatments that are likely to work.

Initial Survey

A national survey of 591 community-based youth smoking cessation programs provided an opportunity to assess the sustainability of health promotion programming over a 3-year period. Initial survey questions were mapped to five sustainability domains (local ownership, organizational alignment, resources, demand, and standard operating procedures) and examined to identify correlates of sustained operation. Follow-up surveys were completed with 305 programs. Assuming loss to follow-up indicated failure to sustain, the overall rate of program continuation was 32%. Baseline correlates of sustaining operation included the following: serving more youth, training staff in smoking cessation, longer time in operation at the initial survey, and receiving state funding as a sole source of support. Primary reasons for discontinuation related to lack of funding, insufficient enrollment, change of focus from tobacco cessation, and scheduling difficulty. Replication of studies like this survey of youth smoking cessation programs with other types of health promotion and public health programming can further test sustainability frameworks, provide validated measures, and ultimately inform a robust and replicable array of lasting, effective, evidence-based public health programs.

Abstract Background Traditional Chinese Medicine Constitution (TCMC, Named Tizhi in Chinese) is essential to reflect an individual’s body-mind and health. Understanding TCMCs and their influencing factors would be beneficial for improving the individual’s health and disease prevention. Earlier our studies have found the characteristics of TCMCs and related influencing factors at a single time point, however, longitudinal data on the development of characteristics of TCMC constitutions over time is limited. Hence, this follow-up study was attempted to investigate the changes in characteristics of TCMCs and explore the factors influencing the development of individual TCMC types at baseline and follow-up. Materials and methods We conducted a follow-up cross-sectional survey of Chinese women in Hong Kong to compare with the characteristics of TCMCs as well as influencing factors related to each TCMC type at baseline with a 4-year interval by using the questionnaires with slight modifications. Statistical methods were employed as similar to that of the initial study including students’ T-test, Chi-square test one way ANOVA, multiple stepwise logistic regression analysis, and association rules mining method. Results A response rate of 59.0% was achieved in the follow-up study. Of 81.5% among 249 participants were diagnosed with unbalanced TCMCs. Qi-deficiency constitution (QDF, 51.8%), Yang-deficiency (PD, 45.4%), and Phlegm-wetness (PW, 38.6%) were still the top three unbalanced TCMCs types and the Yin-deficiency (ND), Blood stasis (BS) and Qi-depressed (QDP) constitutions were significantly increasing. The percentage of owning 1 to 2 unbalanced TCMC types by individual decreased from 30.9% at baseline to 26.9% at follow-up, whereas having 3–6 unbalanced TCMC types had increased from 47.4% at baseline to 58.2% at follow-up. Results of the association mining rules showed the top three paired-unbalanced TCMC types were in QDP paired with QDF (93.75%), PW paired with QDF (85.42%), and PD paired with QDF (81.65%) respectively. Stepwise logistic analysis indicated that poorer health condition (OR, 1.37–2.56), suffering negative effect on body-mind health (OR, 2.70–4.06), negative emotion (OR = 2.57) was significantly positively correlated with certain unbalanced TCMCs. Aging (OR, 0.91–0.93), regular exercise (OR = 0.71) usage of TCM habit (OR = 0.12), and women who experienced menopause (OR, 0.37–0.39) showed inverse correlations with certain unbalanced constitutions. Conclusion Owned unbalanced and more complex TCMC types were the main characteristics of TCMCs in most adult Chinese women in Hong Kong with a 4 -year interval during follow-up. QDF, PD, and PW constitutions were still the top three frequent unbalanced TCMC types at baseline and follow-up, but ND, BS, and QDP constitutions significantly increased during the menopausal stage. Poor health status, unhappy emotions, and/or suffering negative effects on body-mind health and suffering in the menopause stage may be the diverse factors for the development of unbalanced TCMC types, however, regular exercise and habit of regular usage of TCM might be potential protectors for maintaining in the normal constitution.
