MoBA population

The Norwegian population of pregnant women, their children and their partners form the target population. The actual sampling frame consists of pregnant women who attended the routine ultrasound appointment around week 17-20 of pregnancy in participating Norwegian hospitals. Only facilities with more than 100 births per year were targeted. The final sample consisted of women and their partners who gave a written consent to participate (about 40% response). Fathers were included from 2000.
