Associação entre amplitude de distribuição das células vermelhas e estado nutricional em pacientes diabéticos hospitalizados

Abstract

Introduction: Diabetes mellitus is one of the most common chronic diseases today. Recent studies have demonstrated an association between increased red cell distribution width (RDW) values and the incidence of diabetes, as well as an association between diabetes and nutritional status. Materials and methods: Retrospective study using the Hospital Inpatient System (SIH). We included 542 patients diagnosed with diabetes, nutritional status assessment through Global Subjective Assessment (AGS) and request for biochemical tests hospitalized at a tertiary level hospital from January 1, 2014 to December 31, 2016. Results: Of the 542 patients selected, 54.6% were male and were between 18 and 90 years old. The prevalence of malnutrition was 52.6% and 60.4% of the elderly patients were malnourished. The patients who died all had RDW greater than or equal to 13% and 86.4% were malnourished. Nutritional status and death were statistically associated with higher RDW. Conclusions: There is an association between RDW and nutritional status, and patients with alteration in this value are associated with a higher frequency of malnutrition. The use of this inflammatory biochemical marker may be useful in the identification of malnutrition as a complement to the diagnosis.
