In anaemic groups supplementation improved intelligence quotient ( IQ ) by 2.5 points ( 95 % CI 1.24 to 3.76 ) , but had no effect on non-anaemic participants , or on memory , psychomotor skills or scholastic achievement .
Background In observational studies anaemia and iron deficiency are associated with cognitive deficits , suggesting that iron supplementation may improve cognitive function .
However , due to the potential for confounding by socio-economic status in observational studies , this needs to be verified in data from r and omised controlled trials ( RCTs ) .
Aim To assess whether iron supplementation improved cognitive domains : concentration , intelligence , memory , psychomotor skills and scholastic achievement .
Maternal iron deficiency anemia affects postpartum emotions and cognition.
The aim of this study was to determine whether iron deficiency anemia ( IDA ) in mothers alters their maternal cognitive and behavioral performance , the mother-infant interaction , and the infant 's development . This article focuses on the relation between IDA and cognition as well as behavioral affect in the young mothers . This prospect i ve , r and omized , controlled , intervention trial was conducted in South Africa among 3 groups of mothers : nonanemic controls and anemic mothers receiving either placebo ( 10 microg folate and 25 mg vitamin C ) or daily iron ( 125 mg FeS0(4 ) , 10 microg folate , 25 mg vitamin C ) . Mothers of full-term normal birth weight babies were followed from 10 wk to 9 mo postpartum ( n = 81 ) . Maternal hematologic and iron status , socioeconomic , cognitive , and emotional status , mother-infant interaction , and the development of the infants were assessed at 10 wk and 9 mo postpartum . Behavioral and cognitive variables at baseline did not differ between iron-deficient anemic mothers and nonanemic mothers . However , iron treatment result ed in a 25 % improvement ( P < 0.05 ) in previously iron-deficient mothers ' depression and stress scales as well as in the Raven 's Progressive Matrices test . Anemic mothers administered placebo did not improve in behavioral measures . Multivariate analysis showed a strong association between iron status variables ( hemoglobin , mean corpuscular volume , and transferrin saturation ) and cognitive variables ( Digit Symbol ) as well as behavioral variables ( anxiety , stress , depression ) . This study demonstrates that there is a strong relation between iron status and depression , stress , and cognitive functioning in poor African mothers during the postpartum period . There are likely ramifications of this poorer " functioning " on mother-child interactions and infant development , but the constraints around this relation will have to be defined in larger studies
