Early adversities accelerate epigenetic aging into adulthood: a 10-year, within-subject analysis / William E. COPELAND in Journal of Child Psychology and Psychiatry, 63-11 (November 2022)
[article]
Titre : Early adversities accelerate epigenetic aging into adulthood: a 10-year, within-subject analysis Type de document : Texte imprimé et/ou numérique Auteurs : William E. COPELAND, Auteur ; Lilly SHANAHAN, Auteur ; Ellen W. MCGINNIS, Auteur ; Karolina A. ABERG, Auteur ; Edwin J. C. G. VAN DEN OORD, Auteur Article en page(s) : p.1308-1315 Langues : Anglais (eng) Mots-clés : Adolescent Humans Child Young Adult Adult Cross-Sectional Studies Risk Factors Anxiety Disorders Aging/genetics Epigenesis, Genetic Childhood DNA methylation adversity aging epigenetic longitudinal Index. décimale : PER Périodiques Résumé : BACKGROUND: Longitudinal studies are needed to clarify whether early adversities are associated with advanced methylation age or if they actually accelerate methylation aging. This study test whether different dimensions of childhood adversity accelerate biological aging from childhood to adulthood, and, if so, via which mechanisms. METHODS: 381 participants provided one blood sample in childhood (average age 15.0; SD=2.3) and another in young adulthood (average age 23.1; SD=2.8). Participants and their parents provided a median of 6 childhood assessments (total=1,950 childhood observations), reporting exposures to different types of adversity dimensions (i.e. threat, material deprivation, loss, unpredictability). The blood samples were assayed to estimate DNA methylation age in both childhood and adulthood and also change in methylation age across this period. RESULTS: Cross-sectional associations between the childhood adversity dimensions and childhood measures of methylation age were non-significant. In contrast, multiple adversity dimensions were associated with accelerated within-person change in methylation age from adolescence to young adulthood. These associations attenuated in model testing all dimensions at the same time. Accelerated aging increased with increasing number of childhood adversities: Individuals with highest number of adversities experienced 2+ additional years of methylation aging compared to those with no exposure to childhood adversities. The association between total childhood adversity exposure and accelerated aging was partially explained by childhood depressive symptoms, but not anxiety or behavioral symptoms. CONCLUSIONS: Early adversities accelerate epigenetic aging long after they occur, in proportion to the total number of such experiences, and in a manner consistent with a shared effect that crosses multiple early dimensions of risk.

Titre : Impact of dimensions of early adversity on adult health and functioning: A 2-decade, longitudinal study Type de document : Texte imprimé et/ou numérique Auteurs : Ellen W. MCGINNIS, Auteur ; Margaret SHERIDAN, Auteur ; William E. COPELAND, Auteur Article en page(s) : 527-538 Langues : Anglais (eng) Mots-clés : child adversity deprivation life history longitudinal threat Index. décimale : PER Périodiques Résumé : Recent neurodevelopmental and evolutionary theories offer strong theoretical rationales and some empirical evidence to support the importance of specific dimensions of early adversity. However, studies have often been limited by omission of other adversity dimensions, singular outcomes, and short follow up durations. 1,420 participants in the community, Great Smoky Mountains Study, were assessed up to eight times between age 9 and 16 for four dimensions of early adversity: Threat, Material Deprivation, Unpredictability, and Loss (as well as a Cumulative Adversity measure). Participants were followed up to four times in adulthood (ages 19, 21, 25, and 30) to measure psychiatric disorders, substance disorder, and ?real-world? functioning. Every childhood adversity dimension was associated with multiple adult psychiatric, substance, or functional outcomes when tested simultaneously in a multivariable analysis that accounted for other childhood adversities. There was evidence of differential impact of dimensions of adversity exposure on proximal outcomes (e.g., material deprivation and IQ) and even on distal outcomes (e.g., threat and emotional functioning). There were similar levels of prediction between the best set of individual adversity scales and a single cumulative adversity measure when considering distal outcomes. All dimensions of childhood adversity have lasting, pleiotropic effects, on adult health and functioning, but these dimensions may act via distinct proximal pathways.
