Investigation of tobacco and alcohol co-consumption in Thailand: A joint estimation approach

A brief alcohol intervention during smoking cessation treatment in daily cigarette smokers: A pilot randomized controlled trial

Alcohol use attenuates successful smoking cessation. We examined the feasibility, acceptability, and preliminary efficacy of a brief alcohol intervention in smokers. In this two-arm, assessor-blinded randomized controlled trial, we randomized 100 daily smokers (82.0% male, mean age = 43.7 years) with past-year alcohol use in smoking cessation clinics. Both intervention (n = 51) and control (n = 49) groups received conventional smoking cessation treatment, the intervention group additionally received a brief alcohol intervention. Primary outcome was biochemically validated tobacco abstinence at 2 months. Secondary outcomes included Alcohol Use Disorders Identification Test (AUDIT) scores, self-reported past 7-day alcohol consumption in alcohol units, feasibility, and acceptability scores at 2 months. By intention-to-treat, the intervention group showed higher validated abstinence (11.8% vs. 10.2%, Risk Ratio = 1.15, 95%CI = 0.38-3.53), lower AUDIT score (5.3 vs. 6.5), and lower alcohol consumption (5.6 vs. 7.1) than the control group, but the differences were not significant. Overall, the feasibility was high (4.2/5.0), and the acceptability was modest (5.0/7.0). In all participants, reduction in smoking relapse risk due to alcohol use from baseline to 2-month follow-up was associated with higher biochemically validated abstinence (Adjusted odds ratio: 1.55, 95% CI = 1.05-2.28). Our brief alcohol intervention is feasible, acceptable, and potentially efficacious to promote tobacco abstinence and alcohol reduction.

Financial Literacy, Financial Education, and Smoking Behavior: Evidence From Japan

In this study, we examine the relationship between financial literacy, financial education, and smoking behavior among the Japanese population. We hypothesize that financially literate and financially educated people, who have the ability to make more rational decisions, are less likely to smoke. Using the Preference Parameters Study of Osaka University, conducted in 2010 (N = 3,706), the probit regression results show that both financial literacy (with an emphasis on knowledge of investments) and financial education (with an emphasis on savings behavior) have a significant negative impact on smoking behavior. In addition, gender, age, education, marital status, household income and assets, risky behaviors, a myopic view of the future, risk preference, and level of happiness also significantly predict the likelihood of a person being a current smoker. This study provides empirical evidence that enhancing the rational decision-making ability of individuals through financial literacy and financial education may curtail smoking behavior.
