Adolescent peer struggles predict accelerated epigenetic aging in midlife / Joseph P. ALLEN in Development and Psychopathology, 35-2 (May 2023)  

Public ISBD [article]  inDevelopment and Psychopathology > 35-2 (May 2023) . - p.912-925 Titre : Adolescent peer struggles predict accelerated epigenetic aging in midlife Type de document : texte imprimé Auteurs : Joseph P.

Participants (N = 154; 67 male and 87 female) were observed repeatedly, along with close friends and romantic partners, from ages 13 through 29. Observed difficulty establishing close friendships characterized by mutual autonomy and relatedness from ages 13 to 18, an interview-assessed attachment state of mind lacking autonomy and valuing of attachment at 24, and self-reported difficulties in social integration across adolescence and adulthood were all linked to greater epigenetic age at 30, after accounting for chronological age, gender, race, and income. Analyses assessing the unique and combined effects of these factors, along with lifetime history of cigarette smoking, indicated that each of these factors, except for adult social integration, contributed uniquely to explaining epigenetic age acceleration. Results are interpreted as evidence that the adolescent preoccupation with peer relationships may be highly functional given the relevance of such relationships to long-term physical outcomes.

Infant epigenetic aging moderates the link between Black maternal childhood trauma and offspring symptoms of psychopathology / Brooke G. MCKENNA in Development and Psychopathology, 36-4 (October 2024)  

Public ISBD [article]  inDevelopment and Psychopathology > 36-4 (October 2024) . - p.1890-1902 Titre : Infant epigenetic aging moderates the link between Black maternal childhood trauma and offspring symptoms of psychopathology Type de document : texte imprimé Auteurs : Brooke G. MCKENNA, Auteur ; Anna K. KNIGHT, Auteur ; Alicia K. SMITH, Auteur ; Elizabeth J. CORWIN, Auteur ; Sierra E. CARTER, Auteur ; Rohan H.C. PALMER, Auteur ; Anne L. DUNLOP, Auteur ; Patricia A. BRENNAN, Auteur Article en page(s) : p.1890-1902 Langues : Anglais (eng) Mots-clés : child psychopathology  epigenetic aging  intergenerational  trauma Index. décimale : PER Périodiques Résumé : Although offspring of women exposed to childhood trauma exhibit elevated rates of psychopathology, many children demonstrate resilience to these intergenerational impacts. Among the variety of factors that likely contribute to resilience, epigenetic processes have been suggested to play an important role. The current study used a prospective design to test the novel hypothesis that offspring epigenetic aging - a measure of methylation differences that are associated with infant health outcomes - moderates the relationship between maternal exposure to childhood adversity and offspring symptomatology. Maternal childhood adversity was self-reported during pregnancy via the ACEs survey and the CTQ, which assessed total childhood trauma as well as maltreatment subtypes (i.e., emotional, physical, and sexual abuse). Offspring blood samples were collected at or shortly after birth and assayed on a DNA methylation microarray, and offspring symptomatology was assessed with the CBCL/1.5-5 when offspring were 2-4 years old. Results indicated that maternal childhood trauma, particularly sexual abuse, was predictive of offspring symptoms (ps = 0.003-0.03). However, the associations between maternal sexual abuse and offspring symptomatology were significantly attenuated in offspring with accelerated epigenetic aging. These findings further our understanding of how epigenetic processes may contribute to and attenuate the intergenerational link between stress and psychopathology.
