Norwegian Mother and Child Cohort Study

The Norwegian Mother and Child Cohort Study (MoBa) is an ongoing pregnancy cohort study, aiming to include 100 000 pregnancies by 2008. The study is based on questionnaires to the mother and father, with biological specimens being collected from mother, father and child. The main purpose of the study is to find causes of serious diseases in mothers and children. These pages contain information for researchers wanting to use the data for research and for participants in the study.

Approximately 100 subprojects with specific research questions have been proposed. The questions cover environmental factors, such as medication, nutrition, infection and work exposure. Genetic factors and the interplay between genes and the environment will be studied. Blood samples from as many fathers as possible will also be collected, enabling association studies between genes and diseases.

  1. The Norwegian Mother and Child Cohort Study

    What influences how long mothers fully breast-feed?

    breast-feedingNinety-nine percent of the mothers initiated breast-feeding and 80 percent of the infants were still breast-fed at 6 months, although only 2 percent were fully breast-fed at 6 months. At four months of age 87 percent of the children were breast-fed, but only 44 percent were predominantly breast-fed. This was the prevalence of full and partial breast-feeding among participants in the Norwegian Mother and Child Cohort Study (MoBa) during 2002 - 2005.

  3. Infants with severe congenital heart defects: Emotional distress and delayed development

    babyInfants born with severe congenital heart defects (CHD) have an increased risk of irritability, intense crying, and being more difficult to calm than healthy children. These children often display developmental delays more frequently, e.g., in rolling from back to stomach, gripping toys, responding to smiles and reacting to their name. This is shown in new research from the Norwegian Institute of Public Health.

  5. Miscarriage and infertility treatment increase pre-eclampsia risk

    Illustration photoRepeated miscarriages and hormone treatment for infertility give an increased risk of pre-eclampsia among pregnant women. This comes from a new study from the Norwegian Institute of Public Health. More than 20 000 first-time mothers from the Norwegian Mother and Child Cohort Study (MoBa) were included in the study.

  6. Folic acid in early pregnancy may increase risk of respiratory illness

    illustration photoFolic acid supplements are recommended for women who are planning to conceive and in early pregnancy to prevent birth defects such as spina bifida. Although new research from the Norwegian Institute of Public Health has found a slightly increased risk of respiratory disease among infants whose mothers used these supplements, the continued use of folic acid is still advised.

  7. Previous abortions and exercise – do they affect pregnancy?

    illustration photoWomen who have had two or more induced abortions have a reduced risk of pre-eclampsia by 60 %. It is not currently understood to what degree physical activity during pregnancy protects against pre-eclampsia, compared to previous studies. This is shown in two new studies from the Norwegian Institute of Public Health (NIPH) that use data from the Norwegian Mother and Child Cohort Study (MoBa).
