Study acronymParents to Be
Study objectivesAt least 20% of the pregnancies in the Netherlands end in an adverse pregnancy outcome (spontaneous abortion, preterm birth, low birth weight, perinatal death, congenital anomaly). Information on risk factors before pregnancy together with preventive measures (preconception counselling) will lead to behavioural changes and thus to reduced adverse pregnancy outcomes.
Ethics approval(s)Ethics approval received from the Medical Ethics Committee of Leiden University Medical Centre.
Health condition(s) or problem(s) studiedAdverse pregnancy outcome
InterventionIn the intervention group women 18 - 40 years received an invitation for preconception counselling. When interested and contemplating a pregnancy within a year a risk-assessment questionnaire was used to systematically assess risks of the couple. Counselling was provided based on risks identified as well as risks which apply to all women.

The control group received care as usual.
