Report on the identification of a best-practice model of IDD prevention available

When results regarding the current iodine status are available from WP2 statistical analyses of associations between registry-based outcome variables and current iodine status will be performed to show a more detailed picture of the association between iodine intake and IDD-related outcomes across Europe. These analyses will take into account that the actual intake of iodine may vary considerably among countries irrespective of the presence of IDD prevention programs. Special emphasis will be laid on the incidence of hypothyroidism and autoimmune thyroid disease and related treatments. IDD prevention in the country will be defined as best-practice model that will have no socioeconomic gradient in the efficacy of the IDD prevention as well as the most balanced relation between a low prevalence/ decrease of IDD-related outcomes and low prevalence/ increase of hypothyroidism and autoimmune thyroid disease.
