It was shown in Table 2 that longer postpartum time (p = 0.012), overweight or obese (p = 0.013), no iron supplement intake during pregnancy (p = 0.008), less red meat intake (p = 0.014), lower serum vitamin A (p = 0.009), inadequate serum ferritin (p < 0.0001), excessive serum transferrin receptor (p < 0.0001) and anemia during pregnancy (p < 0.0001) were associated with increased risk of anemia in postpartum women. Here, TFRC is linked to anemia (phenotype).
