摘要

Background: Given the established association between sarcopenia and cognitive impairment was mainly in the older and oldest-old population or people with relatively limited education, this study extends the investigation to community-dwelling middle-to-old age adults in urban communities, emphasizing the need for preventive intervention for muscle health and healthy longevity. Methods: Data of 712 participants from the Gan-Dau Healthy Longevity Plan were retrieved for analysis, and all participants were stratified by age (50–64, 65–74 and 75+ years old). Possible sarcopenia was defined by 2019 consensus report of the Asian Working Group for Sarcopenia (AWGS). This study used four neuropsychological tests for analysis, i.e., Mini-Mental Status Examination (MMSE), California Verbal Learning Test II (CVLT-SF), Digital Symbol Substitution Test (DSST) and Verbal fluency (VF) for global and domain-specific cognitive function. Multivariate generalized linear models (GLMs) were employed to investigate the associations between possible sarcopenia and cognitive function in each age-specific groups. Results: The prevalence of possible sarcopenia increased with age, with 31.8 %, 37.7 %, and 55.6 % in participants aged 5064, 65–74 and, 75+ years, respectively. On the other hand, cognitive performance declined with age. In particular, among participants aged 75+ years with possible sarcopenia, their cognitive performance were poorer than robust counterparts, including MMSE (26.6 [3.4] vs. 27.4 [2.6]), CVTL-SF (total score: 21.5 [5.4] vs. 23.8 [5.5]; 30-second delayed recall: 6.0 [1.7] vs. 6.5 [1.6]), DSST (32.8 [14.3] vs. 41.3 [18.7]), and VF (12.8 [5.1] vs. 14.8 [4.9]). Multivariate generalized linear model indicated that possible sarcopenia was associated with lower MMSE (β: −0.70, p = 0.014) and lower DSST (β: −7.00, p = 0.010) in those aged 50–64 years. Moreover, possible sarcopenia was associated with lower CVLT-SF (total score β:-1.90, p = 0.028), lower DSST (β: −6.45, p < 0.001), and lower VF (β: −1.64, p=0.026) in 75+ years group. Conclusions: An association exists between possible sarcopenia and cognitive impairment, encompassing global cognition, delayed memory, verbal fluency, and executive function, among community-dwelling adults of mid-to-old age. Future research is warranted to explore the temporal alterations in this association and the potential effects of interventions aimed at fostering healthy longevity.
