Abstract

The aim of this study was to analyze the association between general working conditions and depressive symptoms among Korean employees. The target population of the study was native employees nationwide who were at least 15 years old, and 50,032 such individuals were enrolled in the study. Depressive symptoms was assessed using the WHO-5 wellbeing index. Associations between general characteristics, job-related characteristics, work environment, and depressive symptoms were tested using chi-square tests, t-tests, and multiple logistic regression analysis. The prevalence of depressive symptoms was 39% (40.7% in males and 36.5% in females). Multiple regression analysis revealed that male subjects, older subjects, subjects with higher education status, subjects with lower monthly income, current smokers, and frequent drinkers were more likely to have depressive symptoms. In addition, longer weekly work hours, occupation type (skilled, unskilled, operative, or economic sector), shift work, working to tight deadlines, exposure to stress at work, and hazard exposure were associated with depressive symptoms. This representative study will be a guide to help manage depression among Korean employees. We expect that further research will identify additional causal relationships between general or specific working conditions and depression.

Highlights

Depression is a debilitating condition that places a huge health burden on society
Data from the fourth European Working Conditions Survey show that employees who spend more time at work have a higher prevalence of depression than those who spend less time at work
Many studies of the link between depression and shift work have found that the prevalence of depression is higher among employees who often work at night compared with those working regular schedules [6]

Summary

Introduction

Depression is a debilitating condition that places a huge health burden on society. The WorldHealth Organization (WHO) ranks it as the leading cause of disability worldwide [1]. Depression is a debilitating condition that places a huge health burden on society. Korean epidemiological survey of mental disorders estimates that the lifetime prevalence of depression is 6.7% [2]. Depression is a major health issue among Korean employees [3,4]. Data from the fourth European Working Conditions Survey show that employees who spend more time at work have a higher prevalence of depression than those who spend less time at work. Employees who experienced depression in the previous year are more likely to work a full week [5]. Many studies of the link between depression and shift work have found that the prevalence of depression is higher among employees who often work at night compared with those working regular schedules [6]
