Background: Depression and anxiety are the commonest mental health disorders worldwide (1). In Qatar, a cross-sectional study conducted among Qatari adolescents in secondary schools in 2017 found that 34.5% have depression with female predominance (5), but no study in Qatar has addressed both disorders co-occurrence. Objectives: The main objective is to assess the prevalence and co-occurrence of major depression disorder and generalized anxiety disorder in adolescents in Qatar. Research participants: adolescents aged 12-18 years old. Method: Cross-sectional study. An online questionnaire including Demographic data, PHQ-9 and GAD-7 will be sent to parents or legal guardians to take online consent, then to be filled in by their children in the ages of 12-18 years old. Proposed analysis: Chi-square test will be used to test the significance of association between variables. The significant level for all statistical analysis was set at 0.05. Anticipated result: According to a previous local study in Qatar we expect the prevalence of both disorders in this age group to be around 30% if not more and as per worldwide studies result 25-50% of depressed patient have anxiety also and 10-15% who have anxiety found to have depression as comorbidity, so we expect to have co-occurrences in this range. Key words: Depression, Generalized Anxiety disorders, Adolescents, Qatar, PHQ-9, GAD-7, cross-sectional.

Background: Depression and anxiety are major health problems found to be associated with various conditions. COVID-19 is a global pandemic that has a substantial effect on the worldwide population. This study aimed to assess the prevalence of depression and anxiety among male patients with COVID-19 and explore their relationship with participants’ characteristics. Methods: This cross-sectional study was conducted among expatriate male patients with COVID-19 admitted to Lebsayyer Field Hospital in Qatar with mild COVID-19 (according to World Health Organization classification) from July till August 2020. The sample size was calculated using Cochran's formula based on disease prevalence. All eligible patients were invited to participate until reaching 400 participants, who then completed an anonymous survey of sociodemographic questions, Patient Health Questionnaire-9, and Generalized Anxiety Disorder-7 questionnaire, which are validated screening tools for depression and anxiety, respectively. Results: Of the 400 participants, 148 (37.0%) and 77 (19.3%) reported depressive and anxiety symptoms, respectively. Depression was more prevalent among those 40–49 years old (p = 0.029), while anxiety was more prevalent among people aged  ≥ 50 (p = 0.456). Both depression (p = 0.009) and anxiety (p = 0.042) were more prevalent among Bangladeshi, followed by Filipino participants. Depression was more prevalent among those with the highest income (> 15,000 QR; p = 0.004), in contrast to anxiety, which was more prevalent among those with the lowest monthly income ( <  2,000 QR; p = 0.039). Conclusion: The prevalence of depressive and anxiety symptoms is high among the study participants. Associated factors identified by the study were unsteady income, poor self-rated health, living with family, Southeast Asian ethnicity, and age group of 40–49 years.
