| Popis: | Background Accumulating evidence indicates that maternal hypothalamic-pituitary-adrenal (HPA) axis activity over pregnancy differs according to maternal history of childhood maltreatment. DNA methylation of the placental 11-beta-hydroxysteroid dehydrogenase (BHSD) type 2 enzyme regulates fetal exposure to maternal cortisol, yet the association between maternal history of childhood maltreatment and methylation of placental 11BHSD type 2 has not been previously studied. Methods We examined if maternal cortisol production at 11 and 32 weeks’ gestation (n = 89) and placental methylation of the 11BHSD type 2 gene (n = 19) differed among pregnant women with and without histories of childhood maltreatment. Twenty-nine percent of participants reported a history of childhood maltreatment (physical/sexual abuse). Results Women with histories of childhood maltreatment displayed lower cortisol in early gestation, hypo-methylation of placental 11BHSD type 2, and lower levels of cord blood cortisol. Conclusion Preliminary results suggest alterations in cortisol regulation over pregnancy according to maternal history of childhood maltreatment. |
