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)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 63-11 (November 2022) . - p.1308-1315 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.

Impact of dimensions of early adversity on adult health and functioning: A 2-decade, longitudinal study / Ellen W. MCGINNIS in Development and Psychopathology, 34-2 (May 2022)

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.

Intergenerational effects of the Fast Track intervention on the home environment: A randomized control trial / William Andrew ROTHENBERG in Journal of Child Psychology and Psychiatry, 64-5 (May 2023)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 64-5 (May 2023) . - p.820-830 Titre : Intergenerational effects of the Fast Track intervention on the home environment: A randomized control trial Type de document : Texte imprimé et/ou numérique Auteurs : William Andrew ROTHENBERG, Auteur ; Jennifer E.

MCMAHON, Auteur ; Natalie GOULTER, Auteur ; Conduct Problems Prevention Research GROUP, Auteur Article en page(s) : p.820-830 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background Maladaptive family environments harm child development and are passed across generations. Childhood interventions may break this intergenerational cycle by improving the family environments children form as adults. The present study investigates this hypothesis by examining follow-up data collected 18?years after the end of the childhood Fast Track intervention designed to prevent externalizing problems. Methods We examined whether Fast Track assignment from grades 1 to 10 prevented the emergence of maladaptive family environments at age 34. A total of 400 (n=206 in intervention condition, n=194 controls) Fast Track participants who were parents at age 34 were surveyed about 11 aspects of their current family environment. The hypotheses and analytic plan were preregistered at https://osf.io/dz9t5 and the Fast Track trial was registered at clinicaltrials.gov (NCT01653535). Results Multiple group linear regression models revealed that mothers who participated in the Fast Track intervention as children had lower depression symptoms, alcohol problems, drug problems, corporal punishment use, and food insecurity compared to control group mothers. All effects were modest in magnitude. However, for these same mothers, the Fast Track intervention had no effect on cannabis problems, experiences of romantic partner violence, or maternal use of physical aggression or warmth with their children. Additionally, mothers in the Fast Track intervention group reported higher levels of family chaos than those in the control group, but this effect may be a byproduct of the higher number of children per household in the intervention group. No intervention effects were found for fathers who participated in the Fast Track intervention as children. Conclusions Childhood assignment to Fast Track has some beneficial effects for girls, but not boys, on the family environments these individuals formed as adults 18?years later.

A methylation study implicates the rewiring of brain neural circuits during puberty in the emergence of sex differences in depression symptoms / Robin F. CHAN in Journal of Child Psychology and Psychiatry, 63-7 (July 2022)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 63-7 (July 2022) . - p.802-809 Titre : A methylation study implicates the rewiring of brain neural circuits during puberty in the emergence of sex differences in depression symptoms Type de document : Texte imprimé et/ou numérique Auteurs : Robin F. CHAN, Auteur ; William E. COPELAND, Auteur ; Min ZHAO, Auteur ; Lin Y. XIE, Auteur ; Jane COSTELLO, Auteur ; Karolina A. ABERG, Auteur ; Edwin J. C. G. VAN DEN OORD, Auteur Article en page(s) : p.802-809 Langues : Anglais (eng) Mots-clés : Brain  DNA Methylation  Depression/genetics  Female  Genome-Wide Association Study  Humans  Male  Puberty  Sex Characteristics  Affective disorders  biomarkers  epigenetics  sex differences Index. décimale : PER Périodiques Résumé : BACKGROUND: Women are 1.5-3 times more likely to suffer from depression than men. This sex bias first emerges during puberty and then persists across the reproductive years. As the cause remains largely elusive, we performed a methylation-wide association study (MWAS) to generate novel hypotheses. METHODS: We assayed nearly all 28 million possible methylation sites in blood in 595 blood samples from 487 participants aged 9-17. MWASs were performed to identify methylation sites associated with increasing sex differences in depression symptoms as a function of pubertal stage. Epigenetic deconvolution was applied to perform analyses on a cell-type specific level. RESULTS: In monocytes, a substantial number of significant associations were detected after controlling the FDR at 0.05. These results could not be explained by plasma testosterone/estradiol or current/lifetime trauma. Our top results in monocytes were significantly enriched (ratio of 2.48) for genes in the top of a large genome-wide association study (GWAS) meta-analysis of depression and neurodevelopment-related Gene Ontology (GO) terms that remained significant after correcting for multiple testing. Focusing on our most robust findings (70 genes overlapping with the GWAS meta-analysis and the significant GO terms), we find genes coding for members of each of the major classes of axon guidance molecules (netrins, slits, semaphorins, ephrins, and cell adhesion molecules). Many of these genes were previously implicated in rodent studies of brain development and depression-like phenotypes, as well as human methylation, gene expression and GWAS studies. CONCLUSIONS: Our study suggests that the emergence of sex differences in depression may be related to the differential rewiring of brain circuits between boys and girls during puberty.
