Abstract
Objective We investigate the relationship between sarcopenia components and depression in geriatric outpatients, considering the effects of potential confounding factors.Methods Adults ≥60 years of age were selected from outpatient clinics. Muscle strength was assessed using handgrip strength (HGS) measured using a hydraulic hand dynamometer and chair stand test (CSST). Physical performance was evaluated by usual gait speed (UGS), nutritional status, and frailty were screened by mini-nutritional assessment (MNA) questionnaire and FRAIL scale. Depression was diagnosed through a psychiatric interview and the administration of the Geriatric Depression Scale (GDS).Results Participants with depression were similar to participants without depression regarding age (p = .055), education (p = .095), frailty (p = .857), and HGS scores (p = .053). The group with depression had longer CSST duration (p = .023), slower UGS (p = .027), and more malnutrition (p = .001). Multivariate regression analysis revealed that only the malnutrition was independently associated factor with depression after adjusting for confounding factors.Conclusions Depression is associated with malnutrition and some components of sarcopenia in geriatric outpatients. Our results revealed that sarcopenia might be associated with depression through malnutrition. If malnutrition lasts for a long time, sarcopenia may become evident in the later stages of depression.
