Частота дифузного нетоксичного зоба у вагітних за умов йодної недостатності

Abstract

The aim of the study was to determine the frequency of goiter in pregnant women and its dependence on iodine excretion. Thyroid volume and ioduria were evaluated in each case at the beginning and at the end of pregnancy. The 105 women who fulfilled all the assumptions of the programme were divided into 2 groups: group А with ioduria below 100 mcg/1 (95 women) and group В with ioduria equal or above 100 mcg/1 (10 women). We found that only in group В ioduria decreased during pregnancy in а statistically significant manner. In group А the tтequency of goiter increased during pregnancy from 41,1 to 64,2% in trimester ІІІ. Thyroid volume increment during pregnancy was greater in group А with lower ioduria. We conclude that ioduria in the majority of pregnant women is below 100 mcg/1, the frequency of goiter among pregnant women is elevated at the beginning of pregnancy and increases throughout pregnancy.
