Exclusive breastfeeding mitigates the association between prenatal maternal pandemic-related stress and children sleep problems at 24 months of age / Sarah NAZZARI ; Massimiliano PASTORE ; Serena GRUMI ; Livio PROVENZI in Development and Psychopathology, 37-4 (October 2025)

The early roots of sleep disturbances are still poorly understood and likely involve a complex interplay between prenatal and postnatal factors. This study investigated whether exclusive breastfeeding during the first 6 months moderated the association between maternal prenatal pandemic-related stress (PRS) and sleep problems in 24-months children born during the COVID-19 pandemic. We also explored the potential contribution of maternal postnatal anxiety in these relations. Seventy-eight infants (50% males) and their mothers provided complete data from birth to 24 months. Between 12 and 48 h from birth, maternal PRS during pregnancy was retrospectively reported as well as maternal anxiety and exclusive breastfeeding. Maternal anxiety and exclusive breastfeeding were also reported at 3 and 6 months after childbirth. Children sleep disturbances were reported at 24 months. Bayesian analyses revealed that maternal PRS was positively associated with sleep problems in children who were not exclusively breastfed from birth to 6 months. Findings add to the growing literature on the lasting impact of early pre- and postnatal experiences on child well-being and development.

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)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 63-8 (August 2022) . - p.871-880 Titre : Maternal caregiving moderates the impact of antenatal maternal cortisol on infant stress regulation Type de document : texte imprimé Auteurs : Sarah NAZZARI, Auteur ; 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.
