TL;DR: The main findings of this study are the perspective of a potential independent interaction of VDBP and adiponectin in both mothers and neonates and the lack of a causative model effect of both maternal/neonatal vitamin D status and adipokine profile on neonatal anthropometry at birth, as a surrogate marker of future metabolic health of the offspring.
Journal ArticleDOI

Journal Article
