Motivation towards first trimester screening for preeclampsia among pregnant women in Denmark: A cross-sectional questionnaire study.

Introduction: The aim of this cross-sectional questionnaire study was to investigate motivation to participate in a possible new screening for preeclampsia in the first trimester of pregnancy among Danish pregnant women through a questionnaire based on Theory of Planned Behavior developed for this specific purpose. The new screening combines maternal characteristics with mean arterial pressure, uterine artery pulsatility index and biochemical markers to predict the risk of preeclampsia, whereas the current Danish screening uses maternal characteristics alone.

Material And Methods: Participation was offered to a proportion of women attending a first or a second trimester screening scan at two University Hospitals in Copenhagen.
