Co-existence of malnutrition and sarcopenia and its related factors in a long-term nursing care facility: A cross-sectional study.

Objectives: Malnutrition and sarcopenia often co-exist in older patients. This condition, called co-MS, shows a worse prognosis than either condition alone but is often overlooked and undertreated. We aimed to clarify the prevalence of co-MS and its associated factors with a focus on prescription in a long-term nursing care facility in Japan. Methods: Patients aged >65 years who resided in a long-term nursing care facility in Hyogo, Japan, were recruited for this cross-sectional study, which was conducted from July 1 to July 30, 2022. Sarcopenia and malnutrition were diagnosed using the Asian Working Group for Sarcopenia and Global Leadership Initiative on Malnutrition criteria, respectively. Patients who met both criteria were classified as having co-MS. Potentially associated factors, including age, sex, length of stay, activities of daily living, comorbidity, oral function and hygiene, swallowing ability, and the number and type of prescriptions, were assessed. Results: The prevalence of sarcopenia was 92 % (72/78). All malnourished patients were sarcopenic (40.3 %) and were classified as having co-MS. Oral function and hygiene, swallowing ability, comorbidity, and the presence of potentially inappropriate medications showed significant associations in univariate analyses. Of particular note, potentially inappropriate medication was an independent factor in the multivariate analysis. Conclusions: Co-MS is prevalent in long-term nursing care facilities; thus, healthcare workers should pay attention to relevant factors to identify patients at risk of co-MS and to provide appropriate care and intervention.
