Objective To systematically review the correlation between sarcopenia and cognitive dysfunction. Methods CNKI, WanFang Data, PubMed, EMbase and Web of Science databases were electronically searched to collect studies on the correlation between sarcopenia and cognitive dysfunction from inception to June 15, 2022. Two reviewers independently screened the literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using RevMan 5.3 and Stata 14.0 software. Results A total of 13 studies involving 19 262 subjects were included. Meta-analysis showed that the cognitive dysfunction was significantly associated with sarcopenia (OR=1.82, 95%CI 1.58 to 2.11, P<0.01). The results of subgroup analysis showed that the cognitive dysfunction was significantly associated with sarcopenia in Asia and Europe. However, the incidence of cognitive dysfunction in the Americas was not significantly associated with sarcopenia. Conclusion Current evidence shows that there is a significant correlation between sarcopenia and cognitive dysfunction, but there may be differences in different regions. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
