Backgrounds

Irregular and unpredictable work schedules have become more common in most societies. The purpose of this study was to investigate the association between unpredictable work schedules and depressive symptoms in Korea.

Methods

Data from 34,486 workers who participated in the Korean Working Condition Survey in 2017 were used. Unpredictable work schedules were measured by questions about the frequency of changes in work schedule and limited advanced notice. Depressive symptoms were assessed by a single item asking if the participants had depressive symptoms over the last 12 months. Multivariable-adjusted logistic regression analysis was used to calculate odds ratios (ORs) for high depressive symptoms.

Results

The OR for depressive symptoms was significantly higher in the workers with unpredictable work schedules compared to those with predictable work schedules after controlling for age, sex, education, salary, marital status, occupation, contract period, full-time versus part-time, shift work, weekly working hours, and having a child under the age of 18 years (OR = 2.43, 95% confidence interval 1.93–3.07).

Conclusion

Unpredictable work schedules were associated with depressive symptoms controlling for the other dimensions of precarious employment in a representative working population in Korea.

韩国不可预测的工作时间表与抑郁症状之间的关联

背景

在大多数社会中，不规则和不可预测的工作时间表变得越来越普遍。本研究的目的是调查韩国不可预测的工作时间表与抑郁症状之间的关联。

方法

使用了 2017 年参加韩国工作条件调查的 34,486 名工人的数据。不可预测的工作时间表是通过有关工作时间表更改频率和有限提前通知的问题来衡量的。抑郁症状通过一个项目评估，询问参与者在过去 12 个月内是否有抑郁症状。多变量调整逻辑回归分析用于计算重度抑郁症状的优势比 (OR)。

结果

在控制了年龄、性别、教育、薪水、婚姻状况、职业、合同期限、全职与兼职、轮班后，与具有可预测工作日程的工人相比，具有不可预测工作日程的工人的抑郁症状 OR 显着更高工作、每周工作时间和有 18 岁以下的孩子（OR = 2.43，95% 置信区间 1.93-3.07）。

结论

在韩国有代表性的工作人口中，不可预测的工作时间表与控制不稳定就业的其他方面的抑郁症状有关。
