WS10‐03Down's syndrome screening by NT measurement: women's opinion

In the context of an implementation study of nuchal translucency (NT) screening for Down's syndrome special attention was devoided to the psycho‐social aspects. The impact of age, parity, religion, education together with the reasons for opting in or out for the NT measurement were recorded in 5895 patients. On a sample of 800 patients more specific aspects were addressed such as the level of knowledge about prenatal diagnosis before and after screening, the reaction to the offer of NT screening and the general women's opinion on whether this form of screening should be offered to all pregnant women. Questionnaires devised to measure the anxiety and depression produced by screening (hads) were filled before screening, at 20 weeks' gestation and after delivery by the same group of patients and by 200 controls. Preliminary results are available. 80% of the asked women, with no differences in age, religion and parity choose for NT screening. Main reason for having the NT measured was the hope of avoiding invasive testing and the wish of having more information on their pregnancy. The majority of women experienced positively NT screening even in case of an increased measurement and irrespectively of whether they would terminate an affected pregnancy or not. A slight increase in anxiety level produced by the screening normalized by 20 weeks' gestation.
