The Prevalence of Depression and Anxiety Disorders Among Postgraduate Students in an Arabic Sample: a Cross-sectional Study
Abstract Background: Depression and anxiety are indicators of mental health and quality of life. Studies found a high prevalence of depression and anxiety disorders among specific populations, such as medical students, residents and fellows. However, postgraduate students unarguably suffer from many private and career life stressors. Unfortunately, research about the prevalence of depression and anxiety among postgraduate students are greatly lacking.Methods: A cross-sectional online survey; a self-questionnaire divided into five sections. Socio-demographic characteristics, the Patient Health Questionnaire for Depression (PHQ9), Generalized Anxiety Disorder 7 item (GAD7), insomnia and suicide.Results: The number of participants was 1,005, The prevalence of depression and GAD that warrant treatments are 27.4% and 23.6%, respectively. Most of the participants who screened positive for depression and GAD were not aware of having these disorders. Females were at a higher risk of depression (OR: 1.5, 95% CL: 1.10 to 2.15) and GAD (OR:1.49, 95% CL 1.07 to 2.07). Insomnia is associated significantly with depression (P<0.001) and GAD (P<0.001). Depression increases the risk for active suicide thoughts (OR= 7.453) (P<0.001). Conclusion: We have identified a higher prevalence of depression and GAD among postgraduate students compared with the general population. However, they appear to be underrepresented in mental health literature, so further research is necessary. The limitations of this study were centered on the nature of cross-sectional studies, causal relationships cannot be identified.
