Screening of nutritional risk: assessment of predictive variables of nutritional risk in hospitalized patients in a second-level care center in Mexico.

Introduction: worldwide, hospital malnutrition constitutes an important issue of morbidity and mortality. Although the prevalence of malnutrition has been calculated as between 7% and 27% in hospitalized patients, its real prevalence remains unknown or underestimated because of the different criteria for its identification and diagnosis. The aim of this study was to determine the prevalence of nutritional risk in a cohort of hospitalized patients and to identify the significance of the predictors associated with nutritional risk.
