Sensitivity analyses and meta-regression for hemoglobin suggested a higher response with lower trial quality ( suboptimal allocation concealment and blinding ) , use of condiments , and sodium iron edetate and a lower response when adults were included .
Consumption of iron-fortified foods results in an improvement in hemoglobin , serum ferritin , and iron nutriture and a reduced risk of remaining anemic and iron deficient
BACKGROUND The utility of iron fortification of food to improve iron deficiency , anemia , and biological outcomes is not proven unequivocally .
Efficacy of iron fortification compared to iron supplementation among Vietnamese schoolchildren
The effect of iron fortification is generally assumed to be less than iron supplementation ; however , the magnitude of difference in effects is not known . The present study aims to compare the efficacy of these two strategies on anaemia and iron status . After screening on low Hb , 425 anaemic children in six primary schools in Tam Nong district of Phu Tho province were included in a r and omized , placebo-controlled trial comparing two groups receiving iron fortified instant noodles or iron supplementation for 6 months and a control group , with children in all groups having been dewormed .  Blood sample s were collected before and after intervention for haemoglobin , serum ferritin ( SF ) , serum transferrin receptor ( TfR ) , C-reactive protein ( CRP ) , and haemoglobinopathies analysis . Regression analysis was used to assess the effect of iron fortification and iron supplementation on haemoglobin concentration , SF , TfR , body iron , and anaemic status as outcome variables . The improvement of haemoglobin , SF , and body iron level in the group receiving iron fortification was 42 % ( 2.6 g/L versus 6.2 g/L ) , 20 % ( 23.5 μg/L versus 117.3 μg/L ) , and 31.3 % ( 1.4 mg/kg versus 4.4 mg/kg ) of that in the iron supplementation group . The prevalence of anaemia dropped to 15.1 % in the control group , with an additional reduction of anaemia of 8.5 % in the iron supplementation group . The additional reduction due to iron fortification was 5.4 % , which amounts to well over 50 % of the impact of supplementation . In conclusion , the efficacy of iron fortification based on reduction of prevalence of anaemia , and on the change in haemoglobin level , is about half of the maximum impact of supplementation in case of optimal compliance . Thus , in a population of anaemic children with mild iron deficiency , iron fortification should be the preferred strategy to combat anaemia
