Summary: This study was to explore epidemiological characteristics of malnutrition and factors associated with malnutrition in centenarians and oldest-old adults, so as to provide a reference for family members and government departments to take effective measures and promote healthy aging. Median age of all 1,654 participants was 100 (85, 102) years old, and prevalence of high malnutrition risk was 65.54% in all participants. Proportion of high-malnutrition risk was higher, and proportion of normal physical function was lower, in centenarians than those in oldest-old adults (p < 0.05 for all). Univariate and multivariate Poisson regression analyses showed that normal physical function was negatively associated with malnutrition risk in all participants, centenarians, and oldest-old adults (p < 0.05 for all). In conclusion, proportion of centenarians at malnutrition risk was significantly higher than that of oldest-old adults, and the independent factor associated with malnutrition in people aged over 80 years was physical function.
