Abstract

Approximately 14% of participants were classified as shift workers.

Evening shift workers have an odds ratio of 1.89 for suicidal ideation compared to day workers, indicating a significantly increased risk.
Night shift workers show an odds ratio of 1.38 for suicidal ideation compared to day workers.
The increased risk of suicidal ideation among shift workers is observed in young and middle-aged male groups.
Adjustments for demographics, lifestyle factors, comorbidities, work hours, and occupational type were made in the analysis.

Objective Studies on the relationship between shift work and suicidal ideation are scarce. This study aimed to investigate the impact of shift work on suicidal ideation using a nationwide representative sample from the Korean working population. Methods The association between shift work and suicidal ideation was determined using data in 17 756 Korean workers over 19 years of age with fixed work schedules. These data were collected from the nationwide cross-sectional Korean National Health and Nutrition Examination Survey (2008-2016). The odds ratios (OR) and 95% confidence intervals (CI) for suicidal ideation were calculated by sex and age using multiple logistic regression models. Results Approximately 14% of included participants were classified as shift workers. Among male workers, evening and night shift workers had a significantly increased risk of suicidal ideation compared to day workers after adjusting for demographics, lifestyle factors, comorbidities, number of work hours, and occupational type (OR 1.89, 95% CI 1.25-2.88 for evening-fixed workers and OR 1.38, 95% CI 1.03-1.86) for night-fixed workers]. Age-stratified analyses indicated that shift workers were more likely to report suicidal ideation than day workers in young and middle-aged groups. Conclusion Evening and night shift work is associated with higher suicidal ideation among male workers.
