title: Socioeconomic and lifestyle factors as risks for suicidal behavior among Korean adults.
abstract: BACKGROUND
  Preventing suicide has become a major public health priority in Korea. The aim of this study was to evaluate the associated factors of suicidal ideation (SI(1)) and attempt (SA(2)) among Korean adults.
  
  
  METHODS
  The data were collected from the Korea National Health and Nutrition Examination Surveys (KNHANES), a nationally representative sample recruited using a multi-stage clustered probability design. The association of putative risk factors focused on nutrition and health behaviors which were evaluated using multiple logistic regression analyses after adjusting for confounding factors. Survey sample weights were used for all analysis.
  
  
  RESULTS
  The 12-month prevalence of SI and SA in Korea was 15.0% and 0.85%, respectively. Female, previously married status, lower education and lower household income were associated with SI and SA. In particular, the effect of age on SI presented a reverse pattern based on gender; there was a positive association for men and a negative association for women. Additionally, drinking, smoking, physical activity above moderate intensity and eating fewer meals were associated with SA in women, whereas regular exercise was protective against SI in men.
  
  
  CONCLUSIONS
  The data were collected using a cross-sectional survey, embedding possible bias.
  
  
  CONCLUSIONS
  Higher prevalence of SI and SA among women was associated with smoking, drinking, avoiding regular exercise and insufficiency of food. Lower prevalence of SI was observed in men who engaged in physical activity while men with insufficient food showed a higher prevalence of SI and SA.
