Prevalence and incidence of anemia in the German Heinz Nixdorf Recall Study.

Abstract

This study aims to determine prevalence and incidence of anemia in the general population in Germany and evaluate a potential role of serum-free light chains (FLC) as biomarker in anemia. The population-based Heinz Nixdorf Recall Study comprises 4,814 men and women aged 45-75 years. Hemoglobin <13 g/dl in men and <12 g/dl in women defined anemia. Laboratory data was used to classify cases into renal, iron deficiency (IDA), vitamin B12/folic acid deficiency, anemia of chronic disease (ACD), and unexplained anemia (UA). Follow-up data was available from annual questionnaires, death certificates, and 5-year follow-up visit (5-year FU). Anemia cases (152) were identified (prevalence 3.2 %, 95 % CI 2.7-3.7). In participants aged 65 or older, prevalence was 4.3 % (95 % CI 2.9-6.0) in both men and women. Main anemia subtypes were: IDA 19 %, ACD 25 %, and UA 44 %. Incidence increased with age and was 12.8/1,000 person-years and 10.9/1,000 person-years in men and women aged 65 or older, respectively. UA was characterized by elevated FLC. Participants with elevated FLC and high-sensitivity C-reactive protein (hsCRP) had an increased risk of anemia at 5-year FU. FLC-alone or in combination with hsCRP-may serve as biomarker indicating an increased risk of developing anemia.
