Aim: The objective of this study was to evaluate associations between maternal concentrations of 25-hydroxyvitamin D (25(OHD)) and birth outcomes: mode of delivery and episiotomy rate.
Design And Methods: One hundred and seventeen pregnant women were enrolled in an observational, longitudinal, prospective cohort study. Multivariable linear regression analyses were performed to assess relationships between maternal 25(OHD) concentrations and mode of delivery.
Research Question: Does the length of the anogenital distance (AGD), an anthropometric biomarker of fetal androgen exposure, change across pregnancy? It has been suggested that AGD remains stable during adulthood with no changes across the menstrual cycle. No studies, however, have been carried out during pregnancy, during which women are exposed to important hormonal and anthropometric variations.
Design: A cohort study of 186 singleton pregnant women recruited in the first trimester of pregnancy.
