11. MoBa – strengths of the study The great number of participants The family structure is the father-mother-child trio, with the possibility of studying twins and siblings The wealth of information The biological specimens The unit of the datacollection is the pregnancy The potential for genetic studies and elucidating gene-environmental interactions
