Nationwide insights into frailty: Systematic review and meta-analysis of community-based prevalence studies from India.

Abstract

Frailty, a biologic syndrome of decreased reserve and resistance to stressors, affects 5 % to 17 % of older adults and is linked to factors like low BMI, female sex, and low exercise levels. With India's older population expected to double by 2050, frailty presents major public health and economic challenges. This study summarizes the prevalence of frailty among community-dwelling Indians. This systematic review and meta-analysis followed PRISMA guidelines to determine the prevalence of frailty among adults in India. We conducted a comprehensive search across multiple databases, including PubMed, Scopus, EMBASE, and Web of Science, up to January 16, 2024, excluding hospital-based studies and reviews. Data were analyzed using STATA software with a random-effects model, and quality was assessed using the JBI Critical Appraisal Checklist. The meta-analysis revealed a pooled frailty prevalence of 36 % (95 % CI: 29 % to 44 %) among 330,007 community-dwelling adults in India, with significant heterogeneity across studies (I² = 99.95 %). Frailty prevalence varied by assessment method, with 48 % using the frailty index and 31 % using the Fried phenotype. Subgroup analyses indicated significant variability in frailty prevalence by gender, data source, and assessment tool, with no significant publication bias detected. This meta-analysis found a pooled frailty prevalence of 36 % and pre-frailty prevalence of 48 % among adults in India, with higher frailty in women (45 %) than men (35 %) and variation across assessment tools. Future research should focus on longitudinal studies and developing tailored frailty assessment tools.
