57(25.8%) students were having mild anemia (Hb% 10.0-11.9 gm/dL), 16(7.2%) had moderate anemia (7-9.9gmdl) and only 0.5% were severely anemic (≤ 7 gm/dl) Mean ± SD of MCV, MCH and MCHC of the anemic subjects were 78.36± 11.7, 24.82± 4.39 and 30± 1.161 respectively. This evidence concerns the gene GSTM1 and anemia (phenotype).
