Problem of iodine insufficiency is still actual as well as 75% of Russian population is living in the area of mild iodine deficiency. To compare iodine supplementation of Saint-Petersburg population in 1999 and 2010. We examined 704 schoolchildren (420 girls and 284 boys) from 6 up to 11 years old, living in Saint-Petersburg. We had took day samples of urine (50 ml) for measuring of iodineurea by well known reaction of Sandell-Kolthoff. All children were examined by endocrinologist, palpation of thyroid gland was performed for revealing of enlargement and nodules. Such examination was made in 1999 and 2010 years. Study which was performed in Saint-Petersburg in 1999 has not revealed severe iodine deficiency and iodineuria mediana was 105 ?g/l but nearly half of examined children had iodineuria less than 100 ?g/l as mild iodine deficiency. In 2010 iodineuria mediana was 148 ?g/l and it was significantly higher than in 1999. In 2010 samples with iodineuria less than 100 ?g/l were revealed three times rare (in15.8% of cases) than in 1999 (49%). Goiter by palpation was found in 3% of schoolchildren in 1999 and in 1.6% in 2010. It was shown that during last ten years iodine supplementation in Saint-Petersburg was significantly improved.
