Consistencia del mini nutritional assessment para identificar la sarcopenia en adultos mayores de hogares geriátricos de Bogotá, Colombia

Abstract

Introduction: malnutrition and sarcopenia, which have similar physiological mechanisms and are both responsible for adverse health outcomes, are highly prevalent in the elderly. Objectives: to measure the consistency of the MNA with the diagnosis of sarcopenia in older adults. Methods: cross-sectional study of consistency in four nursing homes in Bogotá. The nutritional screening and nutritional assessment were made with the Mini Nutritional Assessment in its long form; the diagnosis of sarcopenia was done with the algorithm and the breakpoints of the European Consensus (EWGSOP). Statistical analysis: Pearson Chi2, Mann-Whitney and consistency by Cohen’s kappa coefficient. Results: we included 108 patients, 62% women, mean age 80.4 years (SD 7.7). The prevalence of sarcopenia, malnutrition and risk of malnutrition were 38.9%, 33.3% and 2.8% respectively. The concordance of the MNA with the diagnosis of sarcopenia was slight (kappa 0.1908 95% CI 0.0025 to 0.3791, p < 0.05) Conclusion: MNA shows mild concordance to identify sarcopenia, suggesting that it is not an appropriate tool for the diagnosis of sarcopenia in older institutionalized adults.
