Conclusion Applying the CHERG rules , we recommend a 73 % reduction in anemia at term with daily iron ( alone ) supplementation or iron/folate ( combined ) vs. no intervention or placebo ; for inclusion in the LiST model .
Introduction Iron deficiency is the most prevalent nutrient deficiency in the world , particularly during pregnancy .
According to the literature , anemia , particularly severe anemia , is associated with increased risk of maternal mortality .
It also puts mothers at risk of multiple perinatal complications .
Numerous studies in the past have evaluated the impact of supplementation with iron and iron-folate but data regarding the efficacy and quality of evidence of these interventions are lacking .
This article aims to address the impact of iron with and without folate supplementation on maternal anemia and provides outcome specific quality according to the Child Health Epidemiology Reference Group ( CHERG ) guidelines .
Supplementation with iron and riboflavin enhances dark adaptation response to vitamin A-fortified rice in iron-deficient, pregnant, nightblind Nepali women.
BACKGROUND Nightblindness affects 16 - 52 % of pregnant women in areas of Nepal and in some cases persists after vitamin A treatment . Iron and riboflavin affect vitamin A utilization and photoreceptor function , respectively , and pilot data in the study population showed a high prevalence of iron and riboflavin deficiencies . OBJECTIVE The objective was to assess the effect of supplemental iron and riboflavin on pupillary threshold ( PT ) and plasma retinol in nightblind , pregnant Nepali women given vitamin A-fortified rice . DESIGN Nightblind pregnant women were r and omly assigned to receive , 6 d/wk under supervision for 6 wk , a vitamin A-fortified rice curry dish providing 850 microg retinal activity equivalents/d with either a 30-mg Fe and 6-mg riboflavin ( FeR + VA ) capsule or a placebo control ( VA only ) capsule . Hemoglobin , erythrocyte riboflavin , and plasma ferritin and retinol were measured before and after the intervention . Dark adaptation was assessed by PT score . RESULTS Women who were iron deficient at baseline ( n=38 ) had significantly greater improvement in PT score with  iron and riboflavin supplementation  than without ( P=0.05 ) . Iron and riboflavin supplements significantly reduced the prevalences of riboflavin deficiency ( from 60 % to 6 % ; P<0.0001 ) , iron deficiency anemia ( from 35 % to 15 % ; P<0.007 ) , and abnormal PT ( from 87 % to 30 % ; P<0.05 ) from baseline . Mean increases in erythrocyte riboflavin ( P<0.0001 ) and plasma ferritin ( P=0.01 ) were greater in the FeR + VA group than in the VA only group . CONCLUSIONS Iron deficiency may limit the efficacy of vitamin A to normalize dark adaptation in pregnant Nepali women . Further studies are needed to assess the effect of simultaneous delivery of iron and vitamin A for the treatment of nightblindness
