Gender Differences Among Out-of-School Korean Adolescents in a Counselor-Visiting Smoking Cessation Program.

The purpose of this study was to explore the determinants of self-reported smoking cessation among out-of-school Korean adolescents who participated in a counselor-visiting smoking cessation program. This retrospective descriptive study analyzed data from the Korea Health Promotion Institute. Participants were enrolled between June 1, 2015, and December 31, 2017, at a regional smoking cessation center in a counselor-visiting smoking cessation program for out-of-school adolescents. Participants consisted of 807 adolescents (70.3% male) with a mean age of 16.9 ± 1.2 years. Multiple logistic regression analysis showed that female gender (OR = 1.54-1.92), cohort year 2016 (OR = 1.69-1.90), smoking more than half a pack a day (OR = 0.44-0.50), strong motivation to quit (OR = 1.44), and number of counseling in person (OR = 1.97-2.10) were statistically significant independent contributors to quitting, based on follow-up assessments at 4 weeks, 12 weeks, and 6 months. This study explored smoking cessation outcomes of a government-driven smoking cessation program that targeted out-of-school adolescents and identified several risk factors that affect a successful outcome. More research is necessary to evaluate the efficacy of such smoking cessation programs for marginalized or understudied populations.
