Objective: Our aim is to assess the knowledge, attitude, and behav- iors of pregnant women about COVID-19. Methods: This cross-sectional survey study was performed on preg- nant women in their second and third trimesters between November–December 2020. The participants completed a question- naire consisting of 5 parts. Demographic data of pregnant women, their knowledge, attitude, and risk perceptions toward COVID-19, their practices and worries about COVID-19, and what they knew about pregnancy were calculated as percentile and mean values. Results: A total of 1011 participants were included in the statistical analysis. The mean age and BMI of the participants were 27.09±5.55 and 27.48±4.71 kg/m2 , respectively. Mean gestational age and parity were 26.20±9.30 and 1.47±1.19, respectively. Measures taken by authorities for COVID-19 were thought to be “extremely adequate” by 21.4% of the participants and “highly adequate” by 30%. Of the participants, 47.5% trusted healthcare professionals extremely in fighting against the COVID-19 pandemic. Affection and respect for healthcare professionals during the pandemic increased in 89.1% of the participants. Of the participants, 88.5% stated that they would follow the strict quarantine requirements when necessary and 48.3% felt more vulnerable/weak as they were pregnant during the pan- demic. Of the participants, 50.6% were intending to decrease their antenatal visits during the COVID-19 pandemic. Conclusion: The measures taken can be applied with high aware- ness of COVID-19. Sufficient training, in that case, can be done through communication routes such as information and public service announcements.
