Objective To develop malnutrition risk indicators for community-dwelling older adults，and to enable the early identification of high-risk individuals.Methods Primary indicators were established based on lifestyle medicine theory. The initial draft of malnutrition risk indicators was formulated through literature review and semi-structured interviews, and subsequently revised via two rounds of expert consultation using the Delphi technique.Results The response rate for both rounds of expert consultation questionnaire was 100%. The authority coefficients of the experts were 0.89 and 0.90, respectively. The Kendall′s coefficients of concordance were 0.475 and 0.482 (both P<0.05). The final set of malnutrition risk indicators comprises 3 primary indicators and 19 secondary indicators.Conclusion The malnutrition risk indicators for community-dwelling older adults demonstrate high reliability and rationality, and can provide valuable references for the identification and management of malnutrition risk in this population.
