Article: Increased morning adrenocorticotrophin hormone (ACTH) levels in women with postpartum thoughts of harming the infant.
[show abstract] [hide abstract]
ABSTRACT: Some postpartum women experience intrusive thoughts of harming the infant. The hypothalamic-pituitary-adrenal (HPA) axis, which has been linked to postpartum depression, may play a role in the aetiology of postpartum thoughts of harming the infant. We aimed to study whether HPA axis hormones measured early postpartum are related to postpartum intrusive thoughts. 132 women who delivered a child at a university hospital participated in a follow-up study with visits at 2-3 days postpartum and 8th week postpartum. Participants were assessed for trait anxiety, social support, peripartum or postpartum anxiety or depression, stressful life events and obstetric variables including perinatal complications and lactation. Postpartum thoughts of harming the infant were assessed with a semi-structured interview. Serum cortisol, and plasma CRH and ACTH levels were measured within 48 h postpartum at 8-9 AM. A logistic regression was performed to explore the relationship between clinical variables, hormonal measures and postpartum intrusive thoughts. Patients with postpartum thoughts of harming the infant had, when compared to those women without intrusive thoughts, higher ACTH levels (7.59 pmol/L vs 5.09 pmol/L, p<0.05) without significant differences in CRH or cortisol levels. In the logistic regression analysis, adjusted for breast-feeding and psychopathological status, only ln ACTH was associated with the presence of postpartum thoughts of harming the infant (OR=5.2, CI 95% 1.2-22.6, p=0.029). No other clinical variables were associated with postpartum intrusive thoughts. Our study suggests that a dysregulation of the hypothalamic-pituitary-adrenal axis may play a role in the aetiology of postpartum thoughts of harming the infant.Psychoneuroendocrinology 12/2010; 36(6):924-8. · 5.81 Impact Factor -
Article: Do the emotional states of pregnant women affect neonatal behaviour?
[show abstract] [hide abstract]
ABSTRACT: The emotional states of pregnant women affect the course of their pregnancies, their deliveries and the behaviour and development of their infants. The aim of this study is to analyse the influence of positive and negative maternal emotional states on neonatal behaviour at 2-3 days after birth. A sample of 163 healthy full-term newborns was evaluated using the Neonatal Behavioral Assessment Scale. Maternal anxiety, perceived stress, and emotional stability during pregnancy were evaluated in the immediate postpartum period with the State Trait Anxiety Inventory and the Perceived Stress Scale. Moderate levels of anxiety during pregnancy alter infant orientation and self-regulation. These aspects of infant behaviour could lead to later attachment, behavioural and developmental problems. Maternal emotional stability during pregnancy improves infant self-regulation and several aspects of infant behaviour that may predispose them to better interactions with their parents.Early Human Development 07/2008; 84(11):745-50. · 2.05 Impact Factor
