title: Factors Associated with Successful Smoking Cessation in Korean Adult Males: Findings from a National Survey.
abstract: BACKGROUND
  Smoking cessation rates have remained stagnant globally. This study was conducted to explore the factors associated with successful smoking cessation among South Korean adult males using nationally representative data from the Korea National Health and Nutrition Examination Survey (KNHANES) from 2007 to 2012. A comparison was made between successful quitters and those who failed to quit after attempts to stop smoking.
  
  
  METHODS
  A total of 7,839 males, aged 19-65 years, were included in this cross-sectional study. The outcome measures were the success and failure rates in smoking cessation, sociodemographic and clinical characteristics, health behaviors, perceived health status, quality of life, and mental health. Multiple logistic regression analyses were used to examine the various factors associated with smoking cessation success.
  
  
  RESULTS
  The cessation success and failure rates were 45.5% and 54.5%, respectively. Smoking cessation was related to older age, marriage, higher income, smoking larger amounts of cigarettes, use of willpower, alcohol abstinence, cancer history, better mental health, and higher levels of quality of life, after controlling for multiple variables. Second-hand smoke exposure at home and using nicotine replacement therapy were associated with a lower likelihood of smoking cessation.
  
  
  CONCLUSIONS
  A smoke-free environment, use of willpower, alcohol abstinence, and better stress management are important for smoking cessation. Unlike previous studies, not using nicotine replacement therapy and higher levels of daily cigarette consumption were associated with successful smoking cessation, suggesting that motivation appears to be important to smoking cessation in Korean adult male population.
