Objective To explore the association between cognitive function at baseline and the risk of sar-copenia among a rural elderly population from Shaoxing.Methods Surveys were conducted among the elderly(aged＞60 years)residing in Doumen Street,Shaoxing City,Zhejiang Province,in both 2019 and 2023.The data gathered inl-cuded age,gender,educational attainment,marital status.Cognitive function and sarcopenia status of the participants were also assessed.Multivariate logistic regression analysis was employed to investigate the association between baseline cognitive function scores in 2019 and sarcopenia observed in 2023.Results A total of 368 elderly individuals were in-cluded in the study,with 164 males(44.57％)and 204 females(55.43％).A higher baseline overall cognitive func-tion score was associated with a lower risk of sarcopenia at the 4-year follow-up.This correlation remained significant af-ter adjusting for age,gender,education level,marital status,and chronic conditions(OR=0.93,95％CI:0.86-0.99).Significant correlations were also observed in the attention and memory domains.Multivariable regression analysis showed that a higher baseline cognitive function score was associated with a lower risk of low grip strength at the four-year fol-low-up(OR=0.91,95％CI:0.87-0.96).Cognitive function scores across different domains(attention,executive function/speech,orientation,and memory)were significantly correlated with low grip strength at the four-year follow-up.However,no significant correlation was observed between baseline cognitive function scores and low muscle mass at the 4-year follow-up.Conclusions Individuals with a higher baseline cognitive function score,particularly in the attention and memory,domains have a significant lower risk of sarcopenia at the fourth year.The relationship between lower cogni-tive function and higher risk of sarcopenia is mainly mediated by decreased grip strength.
