Objective To compare the consistency of mini nutritional assessment short form MNA- SF and global leadership initiative on malnutrition GLIM criteria in nutritional assessment among elderly inpatients with chronic obstructive pulmonary disease COPD . Method From January 2020 to December 2021 489 elderly COPD inpatients were randomly selected from the second peoples' hospital of Yibin to assess the nutritional status by MNA-SF and GLIM criteria respectively and to analyze the consistency of two methods. Result 172 35. 17% 228 46. 63% and 89 18. 20% patients were diagnosed good nutrition malnutrition risk and malnutrition by MNA - SF respectively. There were significant differences in MNA - SF scores and malnutrition incidence among different age groups whether combined chronic diseases and course of disease P<0. 05 . The incidence of nutrition risk screening by nutritional risk screening 2002 NRS 2002 was 50. 31% and the incidence of malnutrition diagnosed by GLIM was 28. 83%. The incidence of nutrition risk and malnutrition in <70 years old group was higher than that in ≥70 years old group. The incidence of nutrition risk and malnutrition in the group with chronic disease was higher than that in the group without chronic disease. The longer the course of disease the higher the nutrition risk and malnutrition incidence P<0. 05 . The Kappa value of malnutrition diagnosed by MNA-SF and GLIM was 0. 675 and the Kappa value of nutrition risk diagnosed by NRS 2002 and MNA-SF was 0. 619 while the Kappa value of malnutrition severity level diagnosed by MNA-SF and GLIM was 0. 348 P<0. 05 . Conclusion The nutritional risk and malnutrition rate are high among elderly COPD inpatients. MNA-SF and GLIM criteria can be used to diagnose malnutrition in elderly COPD inpatients.
