Briefly, 7.4% (n = 31/450) of women had a Hb EE homozygous disorder, 2.1% (9/420) and 18.8% (n = 79/420) of nonpregnant women had iron deficiency, based on inflammation‐adjusted serum ferritin (<15 μg/L) and sTfR (>8.3 mg/L), respectively, with no evidence of folate (<3 μg/L), vitamin B12 (<150 pmol/L), or vitamin A deficiency (RBP <0.7 μmol/L). Here, GSTM1 is linked to vitamin A deficiency.
