Geriatric Nutritional Risk Index（GNRI）is a nutritional risk assessment tool for the elderly calculated from Body Mass Index（BMI）and serum albumin level. GNRI score has been known to be correlated with Mini nutritional assessment score and be calculated easily, therefore this index has been utilized as a useful tool to evaluate nutritional status of the elderly staying in nursing homes. The aim of this study is to investigate the relationship between GNRI and indicators of geriatric health status such as activities of daily living（ADL）, cognitive functions, oral functions and number of regular drugs. This cross-sectional study was conducted with the data of 207（40 males, 167 females）nursing home residents examined in 2019 - 2020.　We evaluated GNRI, serum albumin level, BMI, ADL, HDS-R, oral functions, number of regular drugs, and CBC（complete blood count）. Multiple regression analysis was performed by using the obtained data. As a result, GNRI was associated with ADL and HDS-R. BMI and serum albumin, which are components of GNRI, were associated with ADL and HDS-R, respectively. This study suggests that that GNRI is associated with mobility and cognitive functions. Therefore, GNRI could be a useful assessment tool for overall health status of the elderly, not just their nutritional status.
