Prevalence of attention deficit hyperactivity disorder in adults: Umbrella review of evidence generated across the globe.

Background: Attention deficit hyperactivity disorder (ADHD) is a class of neurodevelopmental disorders which is commonly diagnosed in school-age children, but it can occur in any age group. To provide a robust synthesis of published evidence on the prevalence of ADHD in adults, we conducted an umbrella review of systematic reviews and meta-analyses.

Methods: The review was guided by preferred reporting items for systematic review and meta-analysis (PRISMA).

The global prevalence of attention deficit hyperactivity disorder in children and adolescents: An umbrella review of meta-analyses.

Background: Emerging epidemiological data suggest that hundreds of primary studies have examined the prevalence of ADHD in children and adolescents and dozens of systematic view and meta-analyses studies have been conducted on the subject. The purpose of this umbrella review is to provide a robust synthesis of evidence from these systematic reviews and meta-analyses.

Methods: We systematically searched PubMed, Web of Science, PsychINFO, and Scopus to find pertinent studies.

Depression and anxiety among quarantined population during the COVID-19 outbreak in central Ethiopia.

Evidence suggests that quarantine might have a wide-ranging, substantial, and long-lasting negative psychological impact especially when the necessary preventive measures are not taken. This study assessed the prevalence and associated factors of depression and anxiety among quarantined population during the COVID-19 outbreak in central Ethiopia. A community-based cross-section study was conducted among individuals under quarantine from June 5 to July 5, 2020, in Addis Ababa, Ethiopia.

A comparative cross-sectional evaluation of the Field Epidemiology Training Program-Frontline in Ethiopia.

Background: The Field Epidemiology Training Program (FETP)-Frontline is a three-month in-service training aimed at improving surveillance officers' capacity to collect, analyze, and interpret surveillance data, and respond to health emergencies. We evaluated the effectiveness of the FETP-Frontline which was introduced in Ethiopia in 2016.

Methods: We conducted a comparative, randomized cross-sectional study to assess surveillance-related knowledge, skills, and performance among trained and untrained officers using a structured questionnaire and observation checklist.

The prevalence of depression among adolescent with HIV/AIDS: a systematic review and meta-analysis.

Background: Depression is particularly common among adolescents with HIV/AIDS and has been associated with disruption of the important developmental process, subsequently leading to a wide range of negative mental, physical and psychosocial consequences, as well as poor quality of life in those population groups. Nevertheless, to the best of our knowledge, there are no prior systematic reviews and meta-analytic studies that determined the prevalence of depression among adolescents with HIV/AIDS.

Method: We systematically searched PubMed, Scopus and Web of Science for relevant literature until May 2020.

Misdiagnosis, detection rate, and associated factors of severe psychiatric disorders in specialized psychiatry centers in Ethiopia.

Background: There are limited studies on the prevalence of misdiagnosis as well as detection rates of severe psychiatric disorders in specialized and non-specialized healthcare settings. To the best of our knowledge, this is the first study to determine the prevalence of misdiagnosis and detection rates of severe psychiatric disorders including schizophrenia, schizoaffective, bipolar, and depressive disorders in a specialized psychiatric setting.

Method: In this cross-sectional study, a random sample of 309 patients with severe psychiatric disorders was selected by systematic sampling technique.

Prevalence and correlates of diagnosed and undiagnosed epilepsy and migraine headache among people with severe psychiatric disorders in Ethiopia.

Background: There is a paucity of research on the prevalence of diagnosed as well as undiagnosed neurological disorders with episodic manifestations such as epilepsy and migraine headaches in people with severe psychiatric disorders (SPD). To the best of our knowledge, this is the first study analyzing and comparing the prevalence of diagnosed and undiagnosed chronic neurological disorders with episodic manifestations including epilepsy and migraine headache in people with SPD.

Method: This quantitative cross-sectional survey was undertaken among 309 patients with SPD selected by a systematic random sampling technique.

Undiagnosed HIV, hepatitis B, and hepatitis C infections in people with severe psychiatric disorders in Ethiopia.

Background: Worldwide, there is limited epidemiologic evidence on the seroprevalence of undiagnosed chronic viral infections including HIV, hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among patients with severe psychiatric disorders. To our knowledge, this is the first study to explore and compare undiagnosed seroprevalence rates of HIV, HBV, and HCV infections among patients with severe psychiatric disorders.

Method: In this study, we included a random sample of 309 patients with severe psychiatric disorders selected by systematic sampling technique.
