A protocol of a systematic review and meta-analysis on the prevalence of mental health disorders among older adults and synthesis of community-based interventions among them in low- and middle-income countries

Background: Older adults of low- and middle-income countries (LMICs) have a higher prevalence of mental health disorders compared to high-income countries, which can be attributed to a combination of social factors (such as isolation and loss of spouse), declining physical well-being, and the cumulative impact of life stressors, all of which contribute to an increased vulnerability in mental health. Objectives: The objective of this study was to determine the pooled prevalence of mental health disorders among older adults in LMICs and to identify community-based mental health intervention measures to tackle mental health problems in LMICs. Methods: Articles will be retrieved from databases such as PubMed, Scopus, and Cochrane Central using MeSH terms, keywords, and text words for each concept. Preprint search servers (MedRx, Cogprints, IndiaRxiv, medRxiv, and SSRN) will also be accessed. Data analysis will be conducted as per guidelines provided in the Handbook of Cochrane Systematic Review. RevMan version 5.4 software will be used for pooled analysis. Expected outcome: This systematic review will be able to identify the pooled prevalence of mental health among older adults and will also identify the evidence-based mental health intervention measures in community settings among older adults of LMICs.
