3.6 GENERAL CONCLUSIONS
These data indicate a massive global problem. Where IDD have
disappeared in Western countries, this has been brought about by an increased
dietary intake of iodine either through specific supplementation with iodized
salt or by dietary diversification as one of the outcomes of economic
development. The problem can be expected to persist in the absence of either of
these factors. Therefore the effects of iodine deficiency in the form of IDD on
growth and development (Section 2) will continue to be evident. National and
international action is indicated. Priority should be given to those areas and
regions where the persistence of severe IDD can be anticipated as already
pointed out in Section
1.
