Prenatal intimate partner violence exposure predicts infant biobehavioral regulation: Moderation by the brain-derived neurotrophic factor (BDNF) gene.

The ability to regulate stress is a critical developmental milestone of early childhood that involves a set of interconnected behavioral and physiological processes and is influenced by genetic and environmental stimuli. Prenatal exposure to traumatic stress and trauma, including intimate partner violence (IPV), increases risk for offspring biobehavioral regulation problems during childhood and adolescence. Although individual differences in susceptibility to prenatal stress have been largely unexplored, a handful of studies suggest children with specific genetic characteristics are most vulnerable to prenatal stress.

The Effects of Trauma History and Prenatal Affective Symptoms on Obstetric Outcomes.

Prenatal maternal mood may inform the adverse obstetric outcomes seen in disadvantaged populations. The contribution of having a trauma history is not well studied. We examined the impact of trauma exposure and mood symptoms on obstetric outcomes in 358 women.

Depressive symptoms and proinflammatory cytokines across the perinatal period in African American women.

Background: Comparatively few studies have examined the biological mechanisms that may underlie the reported racial disparities in antenatal and postpartum depression.

Objective: To examine the associations among race, depressive symptoms and the proinflammatory cytokines interleukin (IL)-6 and tumor necrosis factor (TNF)-α across the perinatal period in a diverse sample of healthy pregnant women at elevated psychosocial risk.

Methods: 171 subjects were enrolled.

Diurnal cortisol patterns and psychiatric symptoms in pregnancy: short-term longitudinal study.

Alteration in the HPA axis is a robust biomarker of anxiety and depression in adults, but questions remain about this association in pregnancy. We examined the longitudinal links between diurnal cortisol and mood symptoms from self-report questionnaire and diagnostic interview in an ethnically diverse, psychosocially at-risk sample of 101 women at mid-pregnancy and early third trimester. There were modest but significant associations between depression and elevated cortisol, indexed by a decreased morning level and diminished diurnal decline; the effects were strongest for diagnostic data from clinical interview.
