The overall prevalence of inflammation (CRP > 5 mg/L), ID (age-related ferritin concentration < 12 μg/L and < 15 μg/L), IDA (concurrent ID and anaemia) and AI (concurrent anaemia and inflammation in the absence of ID) were respectively, 63.1%, 34.6%, 12.9% and 30.2%. This evidence concerns the gene CRP and anemia.
