Association between current cigarette prices and cessation behaviors among male adult smokers: findings from 2018 to 2020 ITC Vietnam surveys.

BACKGROUND: This study evaluated the impact of the tax increase in January 2019 on changes in intention to quit and the effect of cigarette prices on quit attempts and successful quitting among male cigarette smokers in Vietnam. METHODS: Data were derived from the ITC project in Vietnam, which included 1585 adult smokers at baseline (Wave 1, Aug-Oct 2018) followed up to waves 2 (Sep-Nov 2019) and 3 (Sep-Dec 2020). Generalized estimating equations regression was performed to estimate changes in the intention to quit. Multiple logistic regression analysis was used to evaluate the cigarette price of a cigarette pack in relation to quit attempts and successful quitting. RESULTS: The increase in cigarette tax in 2019 did not significantly increase the likelihood of the intention to quit. After the tax increase, 63.6% of participants who smoked made a quit attempt, and 27.6% successfully quit smoking in the follow-up waves. However, the price of a cigarette pack was not significantly associated with quit attempts and successful quitting. The study did not observe a significant impact of cigarette prices on quit attempts and successful quitting in all subgroups of household income. Factors associated with quit attempts included the number of cigarettes smoked and the intention to quit, while those associated with successful quitting included age, dual use of cigarettes and other tobacco products, and the intention to quit. CONCLUSION: Current cigarette prices were not associated with cessation behaviors even within the lowest household income group. Therefore, a sharp rise in cigarette tax is required to incentivize smokers to quit smoking.

Transtheoretical model to predict the stages of changes in smoking cessation behavior among adolescents.

Introduction: Previous studies on adolescent smoking cessation behavior based on the transtheoretical model have primarily focused on the development of cessation programs. Attempting to quit smoking is a prerequisite for executing smoking cessation. Appropriate methods must be selected based on the characteristics and intentions of individuals to increase smokers' satisfaction and success rates in quitting. Therefore, this study aimed to identify changing processes influencing the stages of change associated with successful smoking cessation among adolescents and examined the related factors. This descriptive study explored a transtheoretical model of different stages of changes in smoking cessation behavior among adolescent smokers. Methods: The participants included 237 middle and high school students in South Korea. We examined the differences in stages of changes in smoking cessation behaviors based on general characteristics, smoking-related characteristics, smoking cessation change processes (cognitive and behavioral), smoking decisional balance (pros and cons of smoking), and self-efficacy. Results: The probability of reaching the preparation stage of smoking cessation was significantly lower among participants who did not know their father's educational level than among those who knew their father's educational level. Conversely, this probability was significantly higher among participants whose mothers had a college or higher education level and those who did not know their mother's educational level than in those whose mothers had a high school or lower education level. Conclusion: These findings indicated that parental education is a significant predictor of the preparation stage of smoking cessation, highlighting the importance of the family environment in facilitating smoking cessation among adolescents. Accordingly, communication and support at home could help reinforce adolescents' determination to quit smoking and make relevant plans. Thus, smoking cessation support should stress the need to enhance communication at home.

Heated tobacco product use frequency, smoking quit attempts, and smoking reduction among Mexican adult smokers.

INTRODUCTION: Heated tobacco products (HTPs) are promoted as less harmful than cigarettes; nonetheless, whether HTPs help smokers quit is uncertain. METHODS: Data from 4067 Mexican adult smokers surveyed longitudinally every four months (November 2019-March 2021) were analyzed. Mixed-effects multinomial models regressed HTP use frequency (no use=reference; monthly; weekly; and daily use) on sociodemographics and tobacco/nicotine-related variables. Among participants who completed at least two surveys (n=2900) over four months, the duration of their longest smoking quit attempt (SQA) between surveys (SQAs: <30 days; ≥30 days; no SQA=reference) was regressed on HTP use frequency, and changes in the number of cigarettes smoked per day were regressed on HTP initiation between surveys, adjusting for covariates. RESULTS: Consistent predictors of all HTP use frequencies (monthly, weekly, or daily vs no use) were daily smoking >5 cigarettes (ARRR=1.69 [95% CI: 1.12-2.55], 1.88 [95% CI: 1.26-2.81] and 6.46 [95% CI: 3.33-12.52], respectively); e-cigarette use (ARRR =5.68 [95% CI: 3.38-9.53], 6.54 [95% CI: 4.06-10.55] and 2.59 [95% CI: 1.26-5.30]); lower HTP risk perceptions (ARRR=2.12 [95% CI: 1.50-30.00], 2.25 [95% CI: 1.63-3.10] and 2.00 [95% CI: 1.25-3.22]); exposure to HTP information inside (ARRR=2.13 [95% CI: 1.44-3.15], 2.13 [95% CI: 1.49-3.05] and 3.72 [95% CI: 2.28-6.09]) and outside stores (ARRR=2.36 [95% CI: 1.56-3.57], 2.32 [95% CI: 1.65-3.25] and 2.44 [95% CI: 1.41-4.24]) where tobacco is sold; having family (ARRR=2.46 [95% CI: 1.54-3.91], 2.90 [95% CI: 1.93-4.37] and 2.96 [95% CI: 1.52-5.77]) and friends (ARRR=5.78 [95% CI: 3.60-9.30], 4.98 [95% CI: 3.22-7.72] and 6.61 [95% CI: 2.91-15.01]) who use HTPs. HTP use frequency was not associated with quit attempts, except for monthly HTP use predicting SQAs lasting ≥30 days (ARRR=2.12 [95% CI: 1.17-3.85]). Initiation of HTP use was not associated with changes in smoking frequency. Limiting analysis to those who intend to quit smoking also yielded null results. CONCLUSIONS: Among Mexican adult smokers, frequency of HTP use was mostly not associated with either cessation behaviors or changes in cigarette consumption, suggesting that HTPs have limited to no effectiveness for smoking cessation.

The evaluation of the smoking cessation behaviors of coal miners according to the health belief model: A cross-sectional study.

The aim of this descriptive and cross-sectional study was to evaluate smoking characteristics and smoking cessation behaviors among smoking coal miners according to the Health Belief Model (HBM). The population of this cross sectional study consisted of 582 coal miners, while the sample consisted of 473 miners who agreed to participate in the study. The miners working above ground obtained significantly higher scores compared to those who worked underground (p = 0.027). There was a significant positive correlation between smoking costs and perceived susceptibility (p < 0.001; r = 0.249) sub dimension scores, while smoking costs also had a weak positive correlation with perceived severity (p < 0.050; r = 0.179). In addition, many sub dimensions of the HBM-SCS were found to be correlated (p < 0.001). This finding shows that workers who have smoking costs may have made smoking cessation a strategic goal. Smoking habits are widespread among coal miners, and it was thought that further efforts should be made to explain to those coal miners the health hazards of smoking.

Analysis of Relationships between the Factors of Personal Characteristics, Experiences, the Factors of Cognition and Affect Relating to Smoking Cessation Behavior / 성인간호학회지

The purpose of the study was to examine if individual characteristics and experiences related to smoking behavior identified from the literature were significantly associated with behavior-specific cognitions and affect in the same way as presented in Pender's Revised Health Promotion Model(Pender, 1996). The subjects selected for this study were 400 college students enrolled in more than 10 colleges located in Seoul and Kyunggi-Inchon province. According to the study results, personal factors (i.e., perceived health status, the past history of disease, and symptoms related to smoking) and related behavior (i.e., the degree of alcohol consumption, and exercise) are significantly associated with behavior-specific cognitions and affect (i.e., perceived barriers to smoking cessation, perceived self-efficacy, and perceived benefits of smoking cessation). The canonical correlation between two groups of variables was .59, and it turned out to be statistically significant. Thirty-four percent of variance of the relationship between two group of variables was explained by two canonical variates which turned out to be significant in the study results. The result could be interpreted from the view of psycho-social area as follows: overall, this study includes important variables which explain the association between two groups of variables.

Analysis for Influences of Individual Characteristics, Experience, Cognition, and Affect Relating to Smoking Quitting Behavior on Commitment to a Plan of and Practice for Smoking Quitting Behavior / 성인간호학회지

This study was conducted to examine if the revised HPM was appropriate to explain smoking quitting behavior. A convenience sample of 400 college students enrolled in the universities located in Seoul and Kyunggi-Inchon province was selected. According to the study results, smoking-specific cognitions and affect included in the study could significantly explain commitment to a plan to quit smoking which was one of the behavioral outcomes in the revised HPM. The study result showed that among predictors, smoking-related affect, perceived benefit of quitting smoking, and perceived self-efficacy significantly explained commitment to a plan to quit smoking, but perceived barriers and interpersonal influences did not. The model for smoking quitting behavior formulated with smoking-specific cognitions and affect was statistically significant and the model explained 48 percent of variance in smoking quitting behavior. More specifically, it was shown that among smoking-specific cognitions and affect, only smoking-related affect, interpersonal influences, and perceived self-efficacy were the significant predictors to explain smoking quitting behavior. Smoking-related affect was the most important variable to explain smoking quitting behavior, followed by perceived self-efficacy. However, the influence of commitment to a plan to quit smoking on smoking quitting behavior was not statistically significant. Lastly, the model for smoking quitting behavior formulated with individual characteristics and experiences could explain 13 percent of the variance in behavior to quit smoking. Although the model is statistically significant, only the number of quitting attempts had significant and direct influence on behavior to quit smoking, while the remaining variables did not.
