Maternal caregiving moderates the impact of antenatal maternal cortisol on infant stress regulation / Sarah NAZZARI in Journal of Child Psychology and Psychiatry, 63-8 (August 2022)
[article]
Titre : Maternal caregiving moderates the impact of antenatal maternal cortisol on infant stress regulation Type de document : Texte imprimé et/ou numérique Auteurs : Sarah NAZZARI, Auteur ; Richard M. PASCO FEARON, Auteur ; Frances RICE, Auteur ; Massimo MOLTENI, Auteur ; Alessandra FRIGERIO, Auteur Article en page(s) : p.871-880 Langues : Anglais (eng) Mots-clés : Adult Anxiety Depression/psychology Depression, Postpartum Female Humans Hydrocortisone/metabolism Infant Male Mother-Child Relations/psychology Mothers/psychology Pregnancy Saliva Stress, Psychological/psychology Cortisol alpha-amylase caregiving inflammation stress Index. décimale : PER Périodiques Résumé : BACKGROUND: Emerging evidence suggests that antenatal exposure to maternal stress signals affects the development of the infant stress response systems. Animal studies indicate that maternal sensitive caregiving can reverse some of these effects. However, the generalizability of these findings to humans is unknown. This study investigated the role of maternal caregiving in the association between multiple markers of maternal antenatal stress and infant stress regulation. METHODS: The sample consisted of 94 mother-infant (N=47 males, mean postnatal weeks=12; SD=1.84) dyads. Maternal levels of Interleukin-6, C-Reactive Protein (CRP), diurnal cortisol and alpha amylase, depressive and anxiety symptoms were assessed in late pregnancy (mean gestational age=34.76; SD=1.12), whereas postnatal symptomatology, caregiving, and infant cortisol response to the inoculation were evaluated at 3months. RESULTS: Hierarchical linear models (HLMs) showed a significant interaction between maternal antenatal cortisol, caregiving, and time on infant cortisol reactivity, while controlling for gender, maternal age, and postnatal depression. Specifically, higher levels of maternal antenatal cortisol were associated with greater cortisol response only among infants of less emotionally available mothers. All other markers of antenatal stress were not significantly associated with infant cortisol reactivity either independently or in interaction with maternal caregiving. CONCLUSIONS: Albeit preliminary, results provide the first evidence in humans that maternal sensitive caregiving may eliminate the association between antenatal maternal cortisol and infant cortisol regulation.
