The purpose of this study was to identify the effect of nutrition related factors on mortality risk among community-residing older adults in Korea. We analyzed data from 8,532 older adults who took part in the 2008 living profiles of older people survey and 2011 death mortality data. According to Cox regression analysis, male (Hazard Ratio [HR], 2.03; 95% Confidence Interval [CI], 1.74~2.37), diabetes mellitus (HR, 1.35; 95% CI, 1.12~1.64), underweighted (HR, 2.68; 95% CI, 2.16~3.31), dysphagia (HR, 1.23; 95% CI, 1.02~1.47), chewing ability (HR, 1.33; 95% CI, 1.11~1.59), and undernutrition (HR, 1.47; 95% CI, 1.23~1.75) significantly affected mortality risk. Systematic nutrition support programs should be developed to decrease the mortality among Korean older adults.
