The Effects of Long Working Hours on Mental Health Among Resident Physicians in Saudi Arabia

Abstract

Purpose: To examine the effect of long working hours on anxiety and depression among resident physicians working in Makkah, Saudi Arabia.

Methods: This is a cross-sectional study using an anonymous and confidential self-administered electronic questionnaire. Mental health status (depression and anxiety) is measured using hospital anxiety and depression scale. A multi-stage stratified sampling technique was used. Data were analyzed using the SPSS version 24.0. The Chi-square test and ordinal logistic regression (OLR) were used to test the association.

Results: A total of 258 medical residents participated in the study. The prevalence of anxiety was 39.5% (n=102) and depression was 20.9% (n=54). In multivariate OLR against anxiety, working more than 64 hours per week was significantly associated (p=0.013) with an increase in the odds of observing a higher level of anxiety (odds ratio=2.91, 95% confidence interval (CI):1.25-6.77) compared with working up to 40 hours per week after adjusting for age, amount of sleep and exposure to injustice. For the depression multivariate OLR, it would increase the odds of observing a higher level of depression for working 41-48, 49-64 and more than 64 hours per week by 2.21 (95% CI:1.07-4.58, P=0.033), 2.07 (95% CI:1.01-4.27, P=0.049) and 2.37 (95% CI:1.03-5.50, P=0.044) respectively, compared with working up to 40 hours per week and adjusting for the amount of sleep and exposure to injustice.

Conclusion: Resident physicians are at increased risk of developing anxiety and depression which is influenced by long working hours and a variety of other factors. Therefore, attention needs to be paid to this association. The implementation of interventions for the prevention and screening of physicians' mental health disorders is needed.
