Aim: The aim of the study was to evaluate the birth weight of children born to women with AITD compared to with those born to women without AITD.

Material and methods: The study included 596 pregnant women and their children in 2007–2015. The patients were divided into two groups. The first (group A) consisted of 191 pregnant women with chronic autoimmune thyroiditis and their children, while the second (group B) consisted of 405 pregnant women without this disease and their children. In each woman, the serum levels of anti-TPO and anti-TG were measured during pregnancy. In newborns birth weight was assessed.

Results: In group A, 191 newborns of women with AITD the average birth weight was 3450 g. In group B, 405 newborns of women without AITD the average birth weight was 3300 g.

Conclusion: The occurrence of autoimmune thyroid disease in pregnant women increases birth weight of their children.
