With ever-increasing prevalence of various mental disorders worldwide, a comprehensive evaluation of the prevalence of co-occurring psychiatric disorders among individuals with autism spectrum disorder (ASD) is needed to strengthen the knowledge base. This umbrella review aims to summarize the current evidence on the prevalence of comorbid psychiatric disorders among people with ASD. A systematic search of 12 major databases and additional sources was conducted. Any systematically conducted narrative, qualitative, or meta-analytic review reporting the prevalence of psychiatric disorders among people with ASD with no age or geographical restriction were included. From a total of 2755 records, 26 articles representing 14 systematic reviews and 12 meta-analyses met the criteria of this review. The synthesized findings reveal a high burden of comorbid psychiatric disorders among people with ASD, including anxiety disorders, depressive disorders, bipolar and mood disorders, schizophrenia spectrum, suicidal behavior disorders, attention-deficit/hyperactivity disorder, disruptive, impulse-control and conduct disorders amongst diverse age groups, with a majority in younger participants. Most studies were conducted in developed nations, with limited evidence from low and middle-income countries. These synthesized findings provide high-quality evidence for clinical and policy-level decision-making from a global overview of the status of comorbid psychiatric disorders among people with ASD.

Objective: Dating violence (DV) is a psychosocial problem which impacts the health and wellbeing of affected individuals. Many studies have reported a high prevalence and various determinants of DV; however, there is a gap of consolidated evidence on this problem. This umbrella review aimed to synthesize the current evidence on the prevalence and determinants of DV from systematic reviews and meta-analyses. Methods: We systematically searched ten major databases and additional sources to retrieve systematic reviews or meta-analyses reporting prevalence or determinants of DV, published as peer-reviewed journal articles in English language till October 13, 2019. We extracted and synthesized the findings, reported the prevalence of DV, and categorized the determinants of DV using the socioecological model. Results: We found 16 eligible systematic reviews and meta-analyses. Most of these studies were conducted in developed countries with a majority of adolescent and young adult participants. Studies reported varying prevalence of physical, sexual, psychological/emotional, and technology-assisted DV ranging from 0.1% to 57.5%, 0.1% to 64.6%, 4.2% to 97%, and 5.8% to 92%, respectively. The determinants of DV at different socioecological levels, including individual behavior, substance abuse, psychiatric conditions, experiencing violence and maltreatment; interpersonal factors like family and peer relationships; community and neighborhood characteristics; patriarchy, culture, and socioeconomic equalities were reported. Conclusions: These findings suggest a high burden of DV among young populations, who are vulnerable to various socioecological determinants of DV. Future research should examine how these factors influence DV and multi-level interventions should be adopted to address the same.
