Mild cognitive impairment (MCI) was assessed by the Mini-Mental State Examination (MMSE) and Instrumental Activities Of Daily Living (IADL). Physical performance was assessed by short physical performance battery (SPPB). Malnutrition was defined with the Mini Nutritional Assessment (MNA). Depressive symptoms were evaluated by the 30-item Geriatric Depression Scale (GDS). Serial multiple mediator models were used.Results: The mean age of the final analysis sample was 73.62± 6.14, and 57.6% (n=809) were females. The prevalence of MCI was 14.35% (n=199). Physical performance (p< 0.001), nutritional status (p=0.025), and depressive symptoms (p=0.002) were correlated with MCI. The serial mediational model revealed that MNA and GDS scores significantly mediated association of SPPB and MMSE scores (c’=0.4728, p< 0.001). Furthermore, depressive symptoms significantly mediated the association of physical performance and cognition (p=0.0311), while malnutrition had no independent mediating effect between these two factors (p=0.794).Conclusion: Our study examined the serial multiple mediation roles of nutritional status and depressive symptoms on the relationship between physical performance and cognitive function in community-dwelling Chinese older adults. Older adults who were in poor physical condition tend to have worse nutritional status, more severe depression, and poorer cognitive function.Keywords: mild cognitive impairment, nutritional status, depressive symptoms, physical functionWu XHou GHan PYu XChen XSong PZhang YZhao YXie FNiu SHu HSun CZhao YWang HGuo QDove Medical Pressarticlemild cognitive impairmentnutritional statusdepressive symptomsphysical functionGeriatricsRC952-954.6ENClinical Interventions in Aging, Vol Volume 16, Pp 1327-1335 (2021) |
