RESUMEN
OBJECTIVE: The aim of this study was to determine whether living with spouse contributes to cognitive decline and depressive symptom among elderly people. METHODS: 939 participants were recruited through Keum-Cheon center for dementia in Seoul. All subjects were assessed using the Korean version of Mini-Mental Status Examination (MMSE-K), Korean version of Consortium to Establish a Registry for Alzheimer's disease (CERAD-K) and Geriatric Depression Scale (GDS). Furthermore, epidemiological factors (age, sex, education year, and characteristics of family) assessed to find correlation with cognitive decline. RESULTS: Controlling for gender, age, and education year, living with spouse was significantly associated with cognitive decline (B=-0.486, S.E=0.203, Wald=0.331, Exp (B)=1.107, p=0.01). Living with spouse group has lower depressive symptom, compared to living without spouse group (F=14.6, p<0.01). CONCLUSION: Correctly, our results suggest that spouse absent state may accelerate cognitive decline and depression. Further, elderly people living alone should be closely monitored for both depression and cognitive impairment.
