title: Major depressive disorder, panic disorder, and post-traumatic stress disorder in Korean subway drivers.
abstract: OBJECTIVE
  The purposes of this study are to investigate the prevalence of major depressive disorder, panic disorder, and post-traumatic stress disorder (PTSD) in Korean subway drivers, and find the association between these disorders and the drivers' person-under-train (PUT) experiences.
  
  
  METHODS
  A total of 826 subway drivers who participated in a cross-sectional work and health survey were included for this study. The Korean version of the Composite International Diagnostic Interview 2.1 was applied to assess major depressive disorder, panic disorder, and PTSD. The date of PUT, whether victim died, and how many PUTs the drivers experienced were asked using a structured questionnaire.
  
  
  RESULTS
  The standardized prevalence ratios (SPRs) for lifetime prevalence of panic disorder and PTSD in subway drivers were 13.3 (95 % confidence interval [CI] 6.6-22.4) and 2.1 (95 % CI 1.1-3.4), respectively. In lifetime prevalence, after adjusting for age, education, income, and working career, the drivers who experienced PUT had significantly higher risks for panic disorder (odds ratio [OR] = 4.2, 95 % CI 1.2-16.6) and PTSD (OR = 4.4, 95 % CI 1.3-16.4). In 1-year prevalence, the drivers who experienced PUT had a significantly higher risk for PTSD (OR = 11.7, 95 % CI 1.9-225.8). There was no significant value of SPR and OR in major depressive disorder.
  
  
  CONCLUSIONS
  This study suggests that Korean subway drivers are at higher risk for panic disorder and PTSD compared to the general population, and PUT experience is associated with panic disorder and PTSD. Drivers who have experienced PUT should be treated quickly, sympathetically, and sensitively by a psychological professional and their colleagues, so they can return to work soon.
