M COOIJMANS, Auteur ; Carolina DE WEERTH, Auteur Article en page(s) : p.136-144 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background Daily skin-to-skin contact (SSC) during early infancy fosters the long-term development of children born preterm. This is the first randomized controlled trial assessing the potential beneficial effects of daily SSC on executive functioning and socio-emotional behavior of children born full-term. Whether children of mothers who experienced prenatal stress and anxiety benefitted more from SSC was also explored. Methods Pregnant women (N=116) were randomly assigned to a SSC or care-as-usual (CAU) condition. Women in the SSC condition were instructed to perform one hour of SSC daily from birth until postnatal week five. Prenatal stress was measured with questionnaires on general and pregnancy-specific stress and anxiety completed by the mothers in gestational week 37. At child age three, mothers filled in questionnaires on children's executive functioning, and externalizing and internalizing behavior. Analyses were performed in an intention-to-treat (ITT), per-protocol, and dose-response approach. Netherlands Trial Register: NL5591. Results In the ITT approach, fewer internalizing (95% CI=0.11-1.00, U=2148.50, r=.24, p=.001) and externalizing (95% CI=0.04-2.62, t=2.04, d=0.38, p=.04) problems were reported in the SSC condition compared to the CAU condition. Multivariate analyses of variance did not show group differences on executive functioning. Additional analyses of covariance showed no moderations by maternal prenatal stress. Conclusions Current findings indicate that early daily SSC in full-term infants may foster children's behavioral development. Future replications, including behavioral observations of child behavior to complement maternal reports, are warranted.

Mother?infant stress contagion? Effects of an acute maternal stressor on maternal caregiving behavior and infant cortisol and crying / Nina BRUINHOF in Journal of Child Psychology and Psychiatry, 66-7 (July 2025)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 66-7 (July 2025) . - p.1040-1052 Titre : Mother?infant stress contagion? Effects of an acute maternal stressor on maternal caregiving behavior and infant cortisol and crying Type de document : Texte imprimé et/ou numérique Auteurs : Nina BRUINHOF, Auteur ; Roseriet BEIJERS, Auteur ; Hellen LUSTERMANS, Auteur ; Carolina DE WEERTH, Auteur Article en page(s) : p.1040-1052 Langues : Anglais (eng) Mots-clés : Postnatal stress  TSST  HPA-axis  stress contagion  caregiving Index. décimale : PER Périodiques Résumé : Background Postpartum maternal distress has been associated with adverse infant outcomes. A potential pathway of how maternal distress affects infant outcomes could be alterations in maternal caregiving behavior. However, the associations between maternal distress, caregiving behavior, and infant outcomes have never been tested in a controlled experiment. This preregistered study utilized an experimental design to investigate the effects of an acute maternal stressor on infant cortisol and crying and the possible mediating role of maternal caregiving behavior. Methods Mother-infant dyads (N?=?91) participated in a lab visit at 8?weeks postpartum, where mothers were separated from their infants to either perform a Trier Social Stress Test (TSST) or a control task. The task was immediately followed by a mother-infant interaction to assess maternal caregiving behavior and infant cortisol and crying. Results Our structural equation model found no differences between conditions (stressor/control) on maternal caregiving behavior and infant response to maternal stress. Secondary findings revealed that higher quality of maternal caregiving behavior was related to lower levels of infant crying and lower cortisol levels at the end of the visit, but not cortisol at reunion. Conclusions Our findings do not support the occurrence of mother-infant stress contagion in this experimental setting but do indicate a link between maternal caregiving behavior and infant behavioral and cortisol responses. Given the high prevalence of maternal mental health problems and their possible negative association with offspring development, further (experimental) research is needed to understand just how maternal postpartum distress affects young infants.
