Objectives: This study was conducted to investigate the relationship between long working hours and suicidal ideation.
Methods: Data based on the fourth Korea National Health and Nutrition Health and Nutrition Examination Survey_(2007~2009) pertaining to a total of 4,539 full-time workers were analyzed. Working hours were divided into four groups (<40 hours/week, 40~51 hours/week, 52~60 hours/week, >60 hours/week). The relationship between working hours and suicidal ideation was then analyzed after adjusting for general and occupational characteristics using a multivariate logistic regression model.
Results: Working 40-51 hours/week showed the lowest suicidal ideation(9.5%), whereas working 52~59 hours/week, over 60 hours/week and less than 40 hours/week showed suicidal ideations of 14.8%, 15.7% and 17.2% respectively. Even after adjusting for general and occupational characteristics, employees working 40~51 hours/week had the lowest suicidal ideation. Working 52~59 hour/week, over 60 hours/week and less than 40 hours/week showed an odds ratios of 1.413(p-value: 0.058), 1.380(p-value: 0.020) and 1.164(p-value: 0.358) respectively.
Conclusions: The results suggest that working long hours, especially over 60 hours per week, is related to suicidal ideation.
