Abstract:
This study examined the association between GNRI and cognitive function in older Americans. Data from NHANES 2011-2014 were used. Three tests were used to measure cognitive function. Nutritional status was calculated by GNRI scores. Subjects were 2283 older adults. Low GNRI levels were a risk factor for normal performance on the AFT and DSST tests.The results of restricted spline regression models indicated an approximately linear dose-response relationship between GNRI and the prevalence of low cognitive performance as tested by AFT and DSST.This study suggested that maintaining a high GNRI level may help sustain the functional stability of certain cognitive function components in the elderly.Ensuring good nutritional status could be beneficial in preventing low cognitive performance.
