The prevalence and associated factors of depression among medical students of Saudi Arabia: A systematic review.

Abstract

The main purpose of our review study was to estimate depression prevalence among Saudi Arabian medical students according to the published articles and try to reveal the main associated factors. A systematic search was performed through PubMed/Medline and Google Scholar databases. A review of 18 studies published between January 2010 and March 2019 was composed of the following selection of necessary articles approved by PICO (population, intervention, control, and outcomes) criteria. The prevalence of depression among medical students of Saudi Arabia ranged from 30.9% to 77.6% with a mean prevalence of 51.5%. Depression severity was evaluated by various questionnaires, so we summarized the extracted data and revealed that medical students tend to have moderate to severe depression to a greater extent than mild depressive symptoms (33.27% vs 29.9%). The findings of this review suggest a high incidence of depression among medical students and the influence of associate sociodemographic factors. Females are considered to be at a higher risk of depression. First-year medical students are the most susceptible to develop depressive symptoms. Smoking is strongly associated with depression severity. Marital status, eating habits, usage of stimulants, and sleep disturbances are within significant findings of our review study.
