The purpose of the present study was to investigate the effectiveness
of the iodine fortification program by comparing iodine
intake and iodine excretion in a population studied both before
iodine fortification and in a follow-up study after iodine fortification
was introduced. Further purposes were to study determinants
for iodine excretion at baseline and at follow-up, and lastly our
follow-up data enabled us to study possible determinants for the
increase in iodine intake.
