Abstract

• Purpose
  The purpose of this study was to determine the relationship between peer and parental factors and smoking behavior of adolescents in urban cities and to investigate whether there are gender differences.
• Methods
  A stratified and random cluster sampling design was used to obtain a cross-sectional sample of high school students in two urban cities. The sample consisted of 512 Korean adolescents (256 boys and 256 girls) aged 15 to 18 (mean age 16.7±.58). Self-reported questionnaire consisted of adolescent smoking behavior, peer smoking and alcohol use, parental smoking and alcohol use, father-mother-peer relationships and perceived social support from peers and parents. Multiple logistic regression analysis was used to examine the hypothesized model.
• Results
  The findings showed that peer and parental factors accounted for 30.3% of the variance in adolescent smoking and peer smoking was most strongly associated with adolescent smoking behavior (OR=10.18). In addition, peer smoking (OR=4.71), peer alcohol use (OR=4.21), and peer relationships (OR=1.03) were significantly associated with boys' smoking behavior. In girls, peer smoking (OR=26.50) and parent smoking (OR=5.48) were significantly associated with smoking behavior.
• Conclusions
  Consistent with previous findings, peer smoking is a significant factor on adolescent smoking. Specifically, boys would be more influenced from peers than girls. Therefore, smoking prevention programs for adolescents might be focused on the social context such as, resisting to peer pressure and enhancing the self-efficacy to control.
