**5. Conclusions**

In conclusions, primiparas showed statistically significantly higher anxiety levels than multiparas. Higher education also contributed to higher scores. Hospital stays during pregnancy contributed to statistically higher STAI-X1 scores. There was no statistically significant relationship between pregnancy trimester and the prevalence of COVID-19. There is a need to continue research on COVID-19-related anxiety among pregnant women in Poland to assess this phenomenon and the causative factors in more detail.

The COVID-19 pandemic has serious consequences. Therefore, in the periods of health crisis, it is imperative to develop research focused on studying the phenomenon and its impact with other variables in order to understand its impact on pregnant women. This can help prevent and address negative mental health effects that can affect the functional status and quality of life of pregnant women.
