Abstract Nitrate inhibits the accumulation of iodide in thyroid gland. The aim of present study was to evaluate the influence of this ion on the iodine status of two risk population groups. Subjects of study were pregnant women and children aged between 3 and 6 years from two villages in Bulgaria with high- and low-nitrate levels in drinking water. The relative risk of thyroid disorders for the pregnant women living in the village with high-nitrate levels in drinking water expressed as an odds ratio was 5.294 (95% confidence intervals 1.003-27.939; P=0.0454) and was considered as significant. Statistically significant differences were found between the goiter rate in exposed and non-exposed pregnant women. The relative risk of thyroid dysfunction for the children exposed to a high-nitrate level, expressed as an odds ratio was 2.333 (95% confidence intervals 0.8491-6.412; P=0.1396) and was considered as not significant; the goiter prevalence in the exposed children was also not statistically different. The results of the study confirmed the role of high-nitrate level in drinking water as a risk factor for thyroid dysfunction in vulnerable population groups.
