The health benefits of physical activity have been well established. However, more than a quarter of the adult population in the world is insufficiently active (not performing at least 150 minutes of moderate-intensity physical activity per week, 75 minutes of vigorous-intensity physical activity per week, or any equivalent combination of the two), and there has been little improvement since 2001. In South Korea, the prevalence of insufficient physical activity was 54.4% in adults and 94.1% in adolescents in 2020. There was continuous decrease in the prevalence of sufficient aerobic physical activity, from 58.3% in 2014 to 45.6% in 2020. However, daily duration of sedentary behavior increased from 7.5 to 8.6 hours in the same period. Interventions to promote physical activity are necessary in various fields including clinical and policy approaches. As physical activity has decreased during the coronavirus disease 2019 pandemic, safer and more effective strategies to promote physical activity are required.

Background: Numerous smokers use electronic cigarettes (e-cigarettes) to stop or reduce smoking. However, the role of e-cigarette use in smoking cessation remains uncertain. Thus, this study aimed to investigate the relationship between e-cigarette use and smoking cessation in Korean adults. Methods: The data of 6,915 ever smokers from the seventh Korea National Health and Nutrition Examination Survey (KNHANES, 2016(KNHANES, -2018 were analyzed. The ever smokers were categorized as "never," "former," and "current" e-cigarette users. Multivariable logistic regression adjusted for sociodemographic factors, alcohol consumption, and stress perception was used to examine the relationship between e-cigarette use and smoking cessation. Results: Ever e-cigarette smokers were negatively associated with quitting smoking for 1 month or more (odds ratio [OR]=0.30, 95% confidence interval [

Background: An evidence-based guideline was formed that addresses several questions regarding pharmacotherapy for smoking cessation among tobacco-dependent adults. Methods: The multidisciplinary guideline panel selected seven clinical key questions and adopted the Grading of Recommendations Assessment, Development, and Evaluation (GRADE)-ADOLOPMENT methodology. The recommendations were verified through literature search and selection, evidence synthesis and evaluation, and the recommendation grade selection process. Results: For smoking cessation in general population, our recommendation is to use varenicline rather than the nicotine patch or bupropion. We conditionally suggest combining varenicline with a nicotine patch instead of using varenicline alone. As for the duration of treatment, we recommend using extended-duration therapy (more than 12 weeks) rather than standard-duration therapy (6-12 weeks). For tobacco-dependent adults who are not yet ready to quit smoking, we recommend initiating treatment with varenicline rather than waiting for them to be ready. In special populations, for adults with a comorbid psychiatric condition, varenicline is preferred over the nicotine patch. Additionally, pharmacotherapy is strongly recommended for adults with chronic obstructive pulmonary disease. Conclusion: Seven recommendations that focused on drug treatment for smoking cessation were developed. Moreover, the guideline panel expects that following these guidelines will increase the effectiveness of smoking cessation intervention.
