title: The Relationship between Smoking and Unhealthy Weight Control Behaviors among Korean Adolescents: The Tenth Korea Youth Risk Behavior Web-Based Survey, 2014.
abstract: BACKGROUND
  Adolescent smoking is positively related to weight control attempts, especially by unhealthy methods. The co-occurrence of smoking and unhealthy weight control behaviors may cause serious health problems in adolescents. This study examined the relationship of smoking with unhealthy weight control behaviors among Korean adolescents.
  
  
  METHODS
  This cross-sectional study involved 31,090 students of grades 7 to 12, who had tried to reduce or maintain their weight during the 30 days prior to The Tenth Korea Youth Risk Behavior Web-based Survey, 2014. Data on height, weight, weight control methods, smoking, alcohol intake, living with one's family, and perceived economic status were obtained through self-report questionnaires. 'Unhealthy weight control behaviors' were subcategorized into 'extreme weight control behaviors' and 'less extreme weight control behaviors.'
  
  
  RESULTS
  The smoking rates were 13.3%±0.4% in boys and 3.8%±0.2% in girls. Current smokers were more likely to engage in extreme weight control behaviors (odds ratio [OR], 1.47; 95% confidence interval [CI], 1.09 to 2.00 in boys, and OR, 2.05; 95% CI, 1.59 to 2.65 in girls) and less extreme weight control behaviors (OR, 1.23; 95% CI, 1.07 to 1.40 in boys, and OR, 1.47; 95% CI, 1.22 to 1.76 in girls) compared to non-smokers among both boys and girls.
  
  
  CONCLUSIONS
  Current smoking is independently related to a high likelihood of engaging in unhealthy weight control behaviors among Korean adolescents. This relationship is stronger for girls than for boys. Extreme weight control behaviors have a stronger relationship with current smoking than less extreme weight control behaviors.
