Sleep Disorders and Risk of Sarcopenia: A Systematic Review and Meta-Analysis

This project aims to systematically synthesize the available observational evidence on the association between sleep disorders and the risk of sarcopenia in adults. Given the growing prevalence of sleep disorders and their potential role in metabolic and musculoskeletal health, this systematic review and meta-analysis will evaluate whether individuals with sleep disorders have a higher risk of developing sarcopenia compared with those without sleep disorders. Relevant observational studies will be identified through comprehensive literature searches, and pooled effect estimates will be calculated to quantify the strength of the association while exploring potential sources of heterogeneity through subgroup and sensitivity analyses. The findings of this study are expected to clarify the overall relationship between sleep disorders and sarcopenia, identify research gaps, and provide evidence to support early prevention and risk stratification strategies in clinical and public health settings.
