Adolescents have become victims of the COVID-19 pandemic, leading to the development of several mental health problems. This protocol is aimed to determine the pooled prevalence of mental health disorders among adolescents (10–19 years) during the COVID-19 pandemic time in low middle-income countries (LMIC) and to find different community-based mental health intervention measures in addressing adolescent mental health disorders during COVID-19 pandemic time in LMIC. Articles will be retrieved from databases such as PubMed, EmBase, Scopus, Cochran Central, and Google Scholar using Medical Subject Headings terms, keywords, and text words for each concept. Preprint search servers (MedRx, Cogprints, IndiaRxiv, medRxiv, SSRN) will also be accessed in addition to hand-searching of retrieved articles by forward and backward searching strategies. Data analysis will be conducted as per guidelines provided in the Handbook of Cochrane Systematic Review. RevMan version 5.4 or suitable software will be used for pooled analysis. This proposal is registered in the PROSPERO register (CRD42021278714). Pooled prevalence will depict the overall burden of these neglected health issues. The proposed study would further suffice in identifying evidence-based intervention measures in community settings among adolescents in the background of an ongoing highly infectious disease pandemic.
