ABSTRACT
BACKGROUND: There has been growing interest in protecting workers' mental health. Identifying social determinants that affect workers' mental health could play an important role in preventing psychiatric diseases. AIMS: We investigated the effects of temporary employment and job dissatisfaction on alcohol use disorder and depressive symptoms. METHOD: The Korea Welfare Panel Study data-set (2009-2021) was used, and 9611 participants with 52 639 observations were included. Generalised linear mixed models were employed to estimate odds ratios and 95% confidence intervals. The relative excess risk due to interaction (RERI) was calculated to assess supra-additive interactions between temporary employment and job dissatisfaction. RESULTS: Increased risks for depressive symptoms were observed among fixed-term workers (odds ratio 1.12, 95% CI 1.00-1.26) and daily labourers (odds ratio 1.68, 95% CI 1.44-1.95). Daily labourers were associated with an increased risk of alcohol use disorder (odds ratio 1.54, 95% CI 1.22-1.95). Job dissatisfaction was associated with alcohol use disorder (odds ratio 1.78, 95% CI 1.52-2.08) and depressive symptoms (odds ratio 4.88, 95% CI 4.36-5.46). This effect became stronger when workers were concurrently exposed to temporary employment and job dissatisfaction. Daily labourers with job dissatisfaction showed the highest risks for alcohol use disorder (odds ratio 2.99, 95% CI 2.21-4.03) and depressive symptoms (odds ratio 9.00, 95% CI 7.36-11.02). RERIs between daily employment and job dissatisfaction were >0 for alcohol use disorder (0.91, 95% CI 0.06-1.76) and depressive symptoms (3.47, 95% CI 1.80-5.14), indicating a supra-additive interaction. CONCLUSIONS: We revealed that temporary employment and job dissatisfaction had detrimental effects on alcohol use disorder and depressive symptoms.
ABSTRACT
Coronavirus disease 2019 (COVID-19) is prevalent around the world, and many studies suggest that depression among medical staff is on the rise during the pandemic. This study aims to assess the relationship between depressive symptoms and individual resilience among military hospital personnel responsible for treating patients with COVID-19. Individuals from the Armed Forces Daejeon Hospital who responded to the questionnaires from 8 February to 15 February 2022 participated in this study. Resilience and depressive symptoms were measured via the Korean Resilience Quotient Test-53 and Patient Health Questionnaire-9, respectively. We employed multivariable logistic regression analysis to estimate Odds Ratios (ORs) and 95% Confidence Intervals (CIs) of depressive symptoms. Among 181 participants, the individuals with depressive symptoms and high resilience accounted for 8.8% and 61.9%, respectively. Significant correlations between depressive symptoms and both the low resilience and low resilience positivity groups were found (adjusted OR 10.30 [95% CI 1.74-61.01] and OR 13.90 [95% CI 1.93-100.02], respectively). This study notes a significant inverse relationship between depressive symptoms and resilience even after adjusting for demographic and occupational characteristics. To overcome depressive symptoms among hospital personnel, it is necessary to seek ways to improve individual resilience, especially positivity.
