Abstract
OBJECTIVES: Malnutrition and sarcopenia frequently coexist in elderly patients. The aim of this study was to assess the effect of nutritional status in the diagnosis of sarcopenia in nursing home residents. METHODS: A cross-sectional study was performed with data collected from 339 elderly patients living in five nursing homes. Sarcopenia was defined according to the consensus definition of the European Working Group on Sarcopenia in Older People. Body mass composition was assessed using bioimpedance analysis, handgrip strength using a dynamometer, and physical performance by 5-m gait speed test. The nutritional status of residents was assessed using the Mini Nutritional Assessment (MNA). RESULTS: Of 436 patients, 339 (77.8%) were included. The mean age of participants was 84.9 y and 64.3% were women. More than one-third (38.1%) of the population had sarcopenia, with a higher prevalence in women (39.4%). According to the MNA, 32.4% of participants were at risk for malnutrition and 42.5% were malnourished. When analyzed together, the presence of malnutrition plus malnutrition risk, there was no difference between individuals with or without sarcopenia. However, the presence of malnutrition was statistically higher in individuals with sarcopenia compared with those without it. The prevalence of malnutrition was highest in individuals with low handgrip strength (62.8%), and in participants with severe sarcopenia. There were no significant differences in calf circumference between sarcopenic and nonsarcopenic participants. In the multivariate logistic regression analysis, body mass index <22 kg/m2 and age >80 y remained predictive of sarcopenia status after adjustment. CONCLUSION: Prevalence of sarcopenia and malnutrition were significant in this population, especially in women. Approximately two-thirds of sarcopenic individuals were malnourished. A low body mass index may be a better predictor of sarcopenia in this population than a small calf circumference (<1 cm).
