Objectives：The aim of this study was to describe subjective physical and mental health assessed by the single item self-rated physical health (SRPH), and self-rated mental health (SRMH) had influence on the cognitive decline in community-dwelling elderly. Methods：This study was based on the Suwon Project, a cohort comprising of non-random convenience samples of ethnic Koreans aged 60 years and above. 1,356 individuals were assessed at 2 time points 2 years apart for questionnaire which included demographic characteristics, medical history, Korean Mini-Mental State Examination (K-MMSE), Korean version of Geriatric Depression Scale (SGDS-K), SRPH, and SRMH. Multiple logistic regression was used to assess K-MMSE score change from the SRPH, and SRMH. Results：At baseline, both SRPH (β=0.18, p＜0.01) and SRMH (β=0.19, p＜0.01) score positively associated with the K-MMSE score. At follow-up, subjects with baseline lower SRMH score had significantly greater decline in K-MMSE score (β=0.09, p=0.007). However, baseline SRPH score showed no effect to follow up K-MMSE score before and after adjusting age, sex, education, number of chronic disease, SGDS-K, and baseline K-MMSE score (p=0.89). Conclusion：Brief and easily collected subjective mental health may predict the risk of cognitive decline, but subjective physical health may not.
