In our study, we observed that LBW (84.62% vs. 55.26%) and SGA (65.38% vs. 32.89%) were statistically more common in newborns of very severely anemic patients (Hb < 4 gm/dL) when compared to patients with severe anemia (Hb ≥ 4 gm/dL but <7 gm/dL). This evidence concerns the gene GSTM1 and anemia (phenotype).
