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 .
Randomized Controlled Trial of Iron-Fortified Drinking Water in Preschool Children
Objectives : To evaluate the effects of fortified drinking water , with different concentrations of iron added , on hemoglobin and hematocrit values in preschoolers . Methods : Double-blind , r and omized cluster clinical trial , with children aged 2 to 5 years of age , from 4 state-run schools , forming 1 group for each school . For fortification , ferrous sulphate in concentrations of 5 mg of elemental iron per liter of water ( group A ) , 7.5 mg ( group B ) , and 10 mg ( group C ) , was used during a period of 4 months . In group D , the control , a placebo ( Bixa orellana ) was added . Hemoglobin and hematocrit values were checked before and after intervention . Results : Before fortification , hemoglobin and hematocrit averages were below the reference values adopted in all groups . After fortification , the prevalence of anemia showed a reduction in the 4 groups , which was more pronounced in group B , at 48.3 % . The hemoglobin values in groups B ( 11.5 ) and C ( 11.4 ) were statistically similar . However , the average consumption of water/day/student was lower in group C. Comparison of hemoglobin values between groups A ( 11.2 ) and D ( 11.0 ) did not show a significant difference , suggesting insignificant efficacy with 5 mg Fe/L fortification . Conclusions : The consumption of drinking water fortified with 7.5 mg of elemental iron/L water result ed in greater adhesion and an increase in hemoglobin values , with a reduction in the prevalence of anemia
