REVIEW ERS ' CONCLUSIONS Despite most of the included studies being of low quality , the results suggest that iodine supplementation , especially iodised oil , is an effective means of decreasing goitre rates and improving iodine status in children .
Indications of positive effects on physical and mental development and mortality were seen , although results were not always significant .
Adverse effects were generally minor and transient .
BACKGROUND Iodine deficiency is the main cause of potentially preventable mental retardation in childhood , as well as causing goitre and hypothyroidism in people of all ages .
It is still prevalent in large parts of the world .
OBJECTIVES To assess the effects of iodine supplementation overall , and of different forms and dosages of iodine supplementation separately , in the prevention of iodine deficiency disorders in children .
Treatment by iodized oil (Lipiodol® UF) of a population in Mali suffering from endemic goiter
In order to reduce the prevalence of goiter in a village of Mali liable to iodine deficiency , an iodized product ( Lipiodol ® Ultra Fluide ) was orally administered to their inhabitants . Taking into account a series of demographic variables and goiter types , a protocol was conducted using Lipiodol at three different dosage levels . Six months after the treatment , the hormone levels regained normal values , whereas only the smallest dose reduces the volume of goiters significantly
