The present study examined the effects of maternal social status, with subordinate status being a chronic stressor, on development and activity of the stress axis in zebrafish embryos and larvae. Female zebrafish were confined in pairs for 48 h to establish dominant/subordinate hierarchies; their offspring were reared to 144 h post-fertilization (hpf) and sampled at five time points over develo...

The purpose of this study was to determine whether maternal mental and physical health is associated with maternal testosterone and cortisol levels, parenting of very low birth weight infants, physical exercise, and White vs non-White race. A total of 40 mothers of very low birth weight infants were recruited from a neonatal intensive care unit at a University Hospital in the Southeast United S...

With a view to examine the effect of chronic maternal stress on cognitive function in the offspring during young age, pregnant Wistar rats were subjected to restraint stress from embryonic day 11 till delivery. Male and female pups born to these stressed rats were subjected to passive avoidance test on postnatal day 30 and 31. Results were compared with rats of the same age and sex born to cont...

The authors examined the relationship between maternal depression, paternal psychopathology, and adolescent diagnostic outcomes in a community sample of 522 Australian families. They also examined whether chronic family stress, father's expressed emotion, and parents' marital satisfaction mediated the relationship between parental psychopathology and adolescent outcomes. Mother's education, chi...

Exposure to stress early in life permanently shapes activity of the hypothalamic-pituitary-adrenocortical (HPA) axis and the brain. Prenatally, glucocorticoids pass through the placenta to the fetus with postnatal impacts on brain development, birth weight (BW), and HPA axis functioning. Little is known about the biological mechanisms by which prenatal stress affects postnatal functioning. This...

BACKGROUND Preterm birth defined as birth prior to 37 weeks of gestation is caused by different risk factors and implies an increased risk for disease and early death for the child. The aim of the study was to investigate the effect of maternal stress during pregnancy on the risk of preterm birth. METHODS A case-control study that included 340 women; 168 women who gave birth preterm and 172 w...

OBJECTIVE To examine parental stress in mothers of boys with Duchenne muscular dystrophy (DMD). METHOD Stress and its predictors were examined in mothers of boys with DMD (n = 112). Comparisons were made with mothers of healthy children (n = 800), children with cerebral palsy (CP; n = 28), siblings of boys with DMD (n = 46), and longitudinally (n = 16). RESULTS The presence of problem child...

BACKGROUND To study in a large-scale cohort with prospective data the associations between psychosocial stress during pregnancy and placenta weight at birth. Animal data suggest that the placenta is involved in stress-related fetal programming. METHODOLOGY/PRINCIPAL FINDINGS We defined a priori two types of psychosocial stress during pregnancy, life stress (perceived burdens in major areas of...
