Pitchika A, et al. - In this prospective cohort study, researchers analyzed data from 5,324 children (0.25 to 6 years of age) of The Environmental Determinants of Diabetes in the Young (TEDDY) study to explore the link between different forms of, and potential pathways between, maternal diabetes and childhood obesity at different ages. Compared with offspring of mothers without diabetes, overweight risk became stronger with increasing age in offspring of mothers with diabetes. Researchers also found that, although maternal body mass index is of greater important in children exposed to gestational diabetes mellitus, intrauterine exposure to maternal type 1 diabetes mellitus might predispose children to later obesity through increased birth weight.
