Controlled trials on infant neurodevelopment were lacking ; gestational iodine supplementation reduced maternal thyroid volume and serum thyroglobulin and in some studies prevented a rise in serum thyroid-stimulating hormone .
Iodine supplementation improves some maternal thyroid indices and may benefit aspects of cognitive function in school-age children , even in marginally iodine-deficient areas .
BACKGROUND Although the detrimental effects of severe iodine deficiency are well recognised , the benefits of correcting mild-to-moderate iodine deficiency are uncertain .
OBJECTIVES We undertook a systematic review of the impact of iodine supplementation in population s with mild-to-moderate iodine deficiency .
Habitual micronutrient intake during and after pregnancy in Caucasian Londoners.
Micronutrient status is of fundamental importance both upon conception and throughout pregnancy . There is an abundance of literature investigating nutrient intakes during individual trimesters of pregnancy but few studies have investigated baseline intakes of nutrients throughout gestation as a continuum . The current investigation set out to measure habitual micronutrient intakes at weeks 13 , 25 , 35 of pregnancy and 6 weeks postpartum using a prospect i ve background information question naire , 4 - 7-day weighed food diary and postnatal question naire . Seventy-two primiparous , Caucasian Londoners were recruited at the study start with 42 completing the first , second , third trimester and postpartum study stages respectively . Study findings indicated that sodium intakes were significantly higher than UK guidelines throughout and after pregnancy ( P < 0.001 ) . Intakes of folate , iron , vitamin D , potassium , iodine and selenium were lower than UK recommendations during and after pregnancy , but to varying levels of statistical significance ( P < 0.05 ) . Only 23 - 38 % of women met UK recommendations for  folate  ( 300 microg day(-1 ) ) through dietary sources . Similarly , only a small percentage of women met dietary guidelines for iron ( 19 - 28 % ) . The findings from the current study indicate that public health interventions may be required to help expectant mothers achieve an optimal diet , particularly after birth when dietary recommendations increase for some micronutrients
