Brief Summary
The aim of this study is to prevent asthma and allergies in childhood by supplementation with fish oil (n-3 fatty acids) to the mother during pregnancy. Paticipants are mother and children participating in the ABC-(Asthma Begins in Childhood)cohort. Mothers are recruited during pregnancy and receive supplement with n-3 fatty acids or olive oil (placebo) from week 24 of gestation to 1 week after delivery. The child is followed with acute and planned visit at the research unit and diagnosis of disease is done in the research unit according to predefined algorithms.
