Pregnant women's knowledge and attitudes to prenatal screening for fetal chromosomal abnormalities: Croatian multicentric survey.

We aimed to assess opinion and preferences of Croatian pregnant women regarding the prenatal screening tests for trisomies. The study was conducted in Zagreb, Split, Cakovec, Nova Gradiska, Gospić and Zlatar. It was organized in the public primary healthcare centers, among the pregnant volunteers during their first visit to an antenatal clinic (7-12 weeks pregnant).
