- Main aim of cohort
Main aim of the cohort: The BaBi study is a prospective cohort study examining the health of 1,000 mother-and-child-pairs in Bielefeld, Germany. The aim is to disentangle the effects of individual and contextual factors among the offspring of migrants and non-migrant. The BaBi-study will help to untangle the underlying reasons for health inequalities between different population groups in Germany under a life course perspective with a focus on the contribution of individual and contextual factors during pregnancy and childhood. Health inequalities will be analyzed in the areas of physical and mental/cognitive development (child), the development of allergies (child), and access to and use of health care (mother and child)
