Introductions. Iodine deficiency is an important goitrogenic factor, which is especially seenin children, adolescents and pregnancy.The Aim. The aim of this study was to evaluate relation between the number of pregnancies,thyroid’s volume and structure.Material and methods. The trial has been started eight years after the introduction of the ob-ligatory household salt iodination among inhabitants of cities and villages of the Mazovianregion, applicants of the Non Public Health Care Clinic. Every women filled in the question-naire and was interviewed by the doctor.The ultrasound examination of the thyroid gland, andevaluation of its size and structure were performed. Iodine concentration in the morning urinesample was also determined. 174 menopaused women were qualifiaed to the analysis.Results. The average age of this group was 52 ± 4.0 years. The mean volume of the thyroidgland was 20.85 ± 21.22 ml. The largest thyroid’s volume was observed among women witha four times history of pregnancy (31.87 ± 33.06 ml). The smallest volume of the gland wasin 2 time pregnant women (17.66 ± 16.00 ml). Only the statistical significance of differencesin thyroid volume was found between the women who have given birth once and twice, andtwo and three times (p = 0.01). The presence of nodules in the thyroid gland was detectedindependently of the number of births. Ioduria below 50μg/l was found in 22,9% investigatedwomen.Conclisions. In conclusion, certain areas of the Mazovian province are still moderately iodinedeficient. There was no correlation between the number pregnancies volume or frequency ofnodules in the thyroid
