RESUMEN
BACKGROUND: Child maltreatment (CM) has severe effects on psychological and physical health. The hypothalamic-pituitary-adrenal (HPA) axis, the major stress system of the body, is dysregulated after CM. The analysis of cortisol and dehydroepiandrosterone (DHEA) in scalp hair presents a new and promising methodological approach to assess chronic HPA axis activity. This study investigated the effects of CM on HPA axis activity in the last trimester of pregnancy by measuring the two important signaling molecules, cortisol and DHEA in hair, shortly after parturition. In addition, we explored potential effects of maternal CM on her offspring's endocrine milieu during pregnancy by measuring cortisol and DHEA in newborns' hair. METHODS: CM was assessed with the Childhood Trauma Questionnaire (CTQ). Cortisol and DHEA were measured in hair samples of 94 mothers and 30 newborns, collected within six days after delivery. Associations of maternal CM on her own and her newborn's cortisol as well as DHEA concentrations in hair were analyzed with heteroscedastic regression models. RESULTS: Higher CM was associated with significantly higher DHEA levels, but not cortisol concentrations in maternal hair. Moreover, maternal CM was positively, but only as a non-significant trend, associated with higher DHEA levels in the newborns' hair. CONCLUSIONS: Results suggest that the steroid milieu of the mother, at least on the level of DHEA, is altered after CM, possibly leading to non-genomic transgenerational effects on the developing fetus in utero. Indeed, we observed on an explorative level first hints that the endocrine milieu for the developing child might be altered in CM mothers. These results need extension and replication in future studies. The measurement of hair steroids in mothers and their newborns is promising, but more research is needed to better understand the effects of a maternal history of CM on the developing fetus.

The postpartum period is a vulnerable period for women with a history of childhood maltreatment. This study investigated the association between childhood maltreatment and postnatal distress three months postpartum and examined the role of social support provided by different sources (intimate partner, parents, parents-in-law, and friends). Analyses are based on N=66 women, who were screened for maltreatment experiences shortly after parturition with the Childhood Trauma Questionnaire. Their levels of postnatal distress (symptoms of depression, anxiety, and stress; assessed with the Hospital Anxiety and Depression Scale and the 4-Item version of the Perceived Stress Scale) and postpartum social support (measured with the Postpartum Social Support Questionnaire) were assessed three months postpartum. Adjusting for educational level and the experience of a recent stressful event, childhood maltreatment was directly associated with higher levels of postnatal distress. Social support provided by friends moderated this association in a heteroscedastic regression analysis. No moderating effect was observed for support provided by the own parents, the intimate partner, or parents-in-law. The association between childhood maltreatment and postnatal distress was not mediated by social support. Additional analyses revealed no main, moderating, or mediating effects of satisfaction with support. Results suggest that support provided by friends may promote resilience during the postpartum period in women with a history of childhood maltreatment. Efforts to better understand the role of postpartum support and mechanisms that may enhance a mother's ability to develop and maintain supportive friendships may be promising for guiding preventive interventions.

Background: Childhood maltreatment (CM) can increase the risk of psychosocial risk factors in adulthood (e.âg. intimate partner violence, financial problems, substance abuse or medical problems). The transition to parenthood presents those affected by CM with particular challenges, in addition to usual birth-related stressors. Methods: In this cross-sectional study a total of 240 women were interviewed in the puerperium with respect to CM experiences, using the German version of the Childhood Trauma Questionnaire (CTQ). Current psychosocial risk factors (e.âg. financial concerns, maternal mental illness, single parent) were assessed using the Constance Index (KINDEX) for early childhood risk factors. Associations between CM experience and psychosocial risk factors were calculated using simple correlation. Results: The average age of participants was 33 years. On the CTQ 13.8â% of participants reported emotional abuse, 6.7â% physical abuse and 12.5â% sexual abuse, while 32.1â% reported emotional neglect and 7.5â% physical neglect during childhood. With rising severity of CM, more psychosocial risk factors (KINDEX) were present. Conclusions: This study shows a clear association between experiences of maltreatment during childhood and the presence of psychosocial stressors among women in the puerperium. Regular screening for a history of CM and parental psychosocial stressors should be conducted early, i.e. during pregnancy, to avoid negative consequences for the child.
