Another previous study noted the role of parasitic infection, dietary intake, and genetic diseases on anemia in children ages 6–23 months in south-central Côte d’Ivoire.19 That study found that malaria and Schistosoma infection, inflammation, and stunting were negatively associated with Hb concentrations and concluded that effective anemia prevention needs to be multifactorial.19 Both their study and ours emphasize the need to address a comprehensive group of factors, including dietary deficiencies and parasitic infections, when addressing early childhood anemias. Here, GSTM1 is linked to anemia (phenotype).
