The Epidemiology of Hemoglobin Levels in Patients With Type 2 Diabetes

Abstract

Background: Anemia is a common finding in patients with diabetes, for whom it constitutes an additional burden. The aim of this study is to clarify the natural history of anemia in patients with type 2 diabetes and describe factors that predict a decrease in hemoglobin (Hb) levels. Methods: A 5-year prospective cohort study was designed as a follow-up of 503 individuals with type 2 diabetes in a single diabetes clinic. In addition to standard management, a full blood count was obtained at each routine visit. No intervention was undertaken to modify Hb levels. Results: At baseline, 12% of patients had anemia, and an additional 13% developed anemia during follow-up. Overall Hb levels decreased..
