Abstract

Abstract : Objective: We investigated the associations between mild cognitive impairment (MCI), social engagement (SE), and mobility. Design: We evaluated data from a cohort study of older adult primary care patients ( N = 430). Outcomes included self-reported function (Late-Life Function Instrument [LLFI]) and performance-based mobility (Short Physical Performance Battery score [SPPB]). Linear regression models evaluated the association between MCI and mobility, MCI and SE, mobility measures and SE, and whether SE mediated the association between MCI status and mobility. Results: Participants with MCI had significantly lower mobility and lower SE as compared with those without MCI (LLFI: 53.5 vs. 56.9, P < 0.001; SPPB: 7.9 vs. 9.3, P < 0.001; SE score: 44.9 vs. 49.0, P < 0.001). Mild cognitive impairment was significantly associated with both LLFI and SPPB (LLFI β = −2.93, P < 0.001; SPPB β = −1.26, P < 0.001) and SE (β = −3.20, P < 0.001). Social engagement was significantly associated with both LLFI and SPPB (LLFI β = 0.22; P < 0.001; SPPB β = 0.08; P < 0.001). There was a positive association between SE and mobility ( P< 0.05). A mediator effect of SE was supported when evaluating the association between MCI and mobility. Conclusions: Among older adult primary care patients at risk for mobility decline, higher levels of SE mitigate the association between MCI and mobility.
