Iodine prophylaxis in Poland - new, old challenges.

For years, the societies of various countries and international organizations have been taking action to eliminate iodine deficiency in iodine-deficient areas. Poland is one of those countries and – similarily to other European countries – it is located within areas with natural goitre endemicity. Since 1997, Poland has a new model of iodine prophylaxis, based on obligatory consumption of iodized salt. The results of numerous studies have proved that these actions contributed to such an increase in iodine intake that Poland has been qualified for the group of countries with sufficient iodine supply [1].
