Introduction: enteral nutrition therapy maintains and/or regains the nutritional status of the common patient in hospital settings, where anemia and malnutrition are food related and are very common diseases.Objective: to determine and associate the presence of anemia and malnutrition in hospitalized patients with exclusive enteral nutrition.Methods: a prospective, cross-sectional study with patients receiving exclusive enteral nutrition up to 72 hours after hospitalization. A nutritional evaluation was performed, consisting of anthropometric data, such as weight, circumferences, and skinfolds; dietary evaluation (data were collected through an electronic medical record) and biochemistry data (hemogram, albumin, C-reactive protein, capillary glucose monitoring).Results: the population consists of 77 individuals. As the patients presented greater severity of anemia, corrected arm muscle area, calf circumference and serum albumin levels were reduced while C-reactive protein increased signifi cantly (p < 0.05). In relation to the low weight classifi cation according to the body mass index (BMI), it was observed that the anthropometric parameters such as corrected arm muscle area (R = 0.74, p < 0.001), adductor pollicis muscle thickness (R = 0.23, p = 0.046) and calf circumference (R = 0.81, p < 0.001) decreased as did biochemical parameters albumin (R = 0.26; p = 0.048) and capillary blood glucose (R = 0.34, p = 0.018).Conclusion: anemia has an important relation with anthropometric markers that evaluate the depletion of lean mass; the BMI has a strong association with all the anthropometric parameters evaluated, as well as the albumin and capillary blood glucose, except with the values of hemoglobin.
