Initiatives -
To identify causes of diseases among mothers, fathers and children.The main aim of MoBa is to detect causes of serious diseases through estimation of specific exposure-outcome associations especially among the children but also among parents. It has, however, become clearer that MoBa contributes to the description of disease trajectories and comorbidities, as well as to the analyses of factors that are associated with progression of disease. MoBa also serves as a source of research on the social determinants of health and on health as a determinant of educational, social and economic achievement. **General information:**
