Summary: | Abstract Objectives Malnutrition and sarcopenia frequently coexist in older patients. The main objective of this study was to assess the impact 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 living in five nursing homes. Sarcopenia was defined according to the consensus definition of the EWGSOP. Body mass composition was assessed using bioimpedance analysis, handgrip strength using a dynamometer, and physical performance by 5-meter gait speed test. The nutritional status of residents was assessed with Mini Nutritional Assessment (MNA). Results 339 (77.8%) out of 436 subjects were included. Mean age was 84.9 years and 64.3% were females. 38.1% of the population had sarcopenia, with a higher prevalence in females (39.4%). According to MNA, 32.4% of participants were at risk of 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 to the non-sarcopenic ones. The prevalence of malnutrition was highest in subjects with low hand grip strength (62.8%), and in participants with severe sarcopenia. There were no significant differences in calf circumference between sarcopenic and non-sarcopenic participants. In the multivariate logistic regression analysis, BMI< 22 kg/m2 and age > 80 years remained predictive of sarcopenia status after adjustment. Conclusion prevalence of sarcopenia and malnutrition were significant in this population, especially in women. Around two thirds of sarcopenic subjects were malnourished. A low BMI may be a better predictor of sarcopenia in this population than a low calf circumference (< 31cm). |
