Biomarkers in the Hypothalamus-pituitary-adrenal Axis Were Associated with Maternal Psychosocial Stress and Choline Intake and Status During Pregnancy (P11-011-19)

摘要

ObjectivesMaternal psychosocial stress during pregnancy can lead to heightened activity of the hypothalamus-pituitary-adrenal (HPA) axis, increasing the risk of pre-term birth, intrauterine restriction, and preeclampsia. Maternal dietary intakes and nutrition status modify epigenetic marks in the placental and fetal HPA axis, which may then counter the negative influence of maternal stress. This study aims to determine the correlation of maternal psychosocial stress and nutrient intakes with biomarkers of HPA axis activity in human pregnancies.
