Prenatal unhealthy diet, insulin-like growth factor 2 gene (IGF2) methylation, and attention deficit hyperactivity disorder symptoms in youth with early-onset conduct problems / Jolien RIJLAARSDAM in Journal of Child Psychology and Psychiatry, 58-1 (January 2017)

Titre : Prenatal unhealthy diet, insulin-like growth factor 2 gene (IGF2) methylation, and attention deficit hyperactivity disorder symptoms in youth with early-onset conduct problems Type de document : Texte imprimé et/ou numérique Auteurs : Jolien RIJLAARSDAM, Auteur ; Charlotte A.

Early-life diet also associates with DNA methylation of the insulin-like growth factor 2 gene (IGF2), involved in fetal and neural development. We investigated the degree to which prenatal high-fat and -sugar diet might relate to ADHD symptoms via IGF2 DNA methylation for early-onset persistent (EOP) versus low CP youth. Methods Participants were 164 youth with EOP (n = 83) versus low (n = 81) CP drawn from the Avon Longitudinal Study of Parents and Children. We assessed if the interrelationships between high-fat and -sugar diet (prenatal, postnatal), IGF2 methylation (birth and age 7, collected from blood), and ADHD symptoms (age 7–13) differed for EOP versus low CP youth. Results Prenatal ‘unhealthy diet’ was positively associated with IGF2 methylation at birth for both the EOP and low CP youth. For EOP only: (a) higher IGF2 methylation predicted ADHD symptoms; and (b) prenatal ‘unhealthy diet’ was associated with higher ADHD symptoms indirectly via higher IGF2 methylation. Conclusions Preventing ‘unhealthy diet’ in pregnancy might reduce the risk of ADHD symptoms in EOP youth via lower offspring IGF2 methylation.

Titre : Promoting better functioning among children exposed to high levels of family adversity: the protective role of childcare attendance Type de document : Texte imprimé et/ou numérique Auteurs : M. P. LAROSE, Auteur ; Sylvana M. CÔTÉ, Auteur ; I. OUELLET-MORIN, Auteur ; B. MAUGHAN, Auteur ; Edward D. BARKER, Auteur Article en page(s) : p.762-770 Langues : Anglais (eng) Mots-clés : Adolescent Child Child Behavior Disorders Child Care Child Health Female Humans Longitudinal Studies Pregnancy Problem Behavior adversity childcare cognitive development externalizing behaviors prevention Index. décimale : PER Périodiques Résumé : BACKGROUND: Children exposed to early adversity are vulnerable to cognitive impairments and externalizing behaviors. Attending childcare may, however, partly buffer this detrimental effect by providing social and cognitive stimulation in a secure environment. The aims of this study were (a) to determine whether the association between exposure to adversity and later externalizing behaviors is mediated by children's cognitive abilities, and (b) to examine if childcare attendance moderates this mediation-thereby highlighting a protective function of children's childcare attendance. METHODS: Data come from the Avon Longitudinal Study of Children and Parents (N = 6,149). Exposure to adversity was assessed by maternal reports three times from the second trimester of the mother's pregnancy to the child's fourth year of age. Childcare attendance was assessed on four occasions between eight months and three years of age. Factors explaining differences in childcare attendance were controlled using propensity score weights. Children's cognitive abilities were assessed by the Weschler Intelligence Scale for Children at eight years of age, and externalizing behaviors were reported by mothers using the Development and Well-Being Assessment interview at 10, 13, and 15 years of age. RESULTS: Notably, lower cognitive abilities partly accounted for the higher levels of externalizing behaviors in adolescents exposed to adversity (B indirect effect = 0.02, 95% CI = 0.007-0.03, p < .01). Importantly, childcare attendance moderated this indirect effect. For children exposed to adversity, being in maternal care was associated with lower cognitive abilities which were related to higher levels of externalizing behaviors. On the contrary, for children exposed to adversity, attending childcare was associated with higher cognitive abilities which were linked to lower levels of externalizing behaviors. CONCLUSIONS: Easily accessible community childcare may be a relatively low-cost public health strategy to prevent the emergence of externalizing behavioral problems in adolescence through its positive effects on cognitive abilities.

[article]
Titre : Research review: A critical review of studies on the developmental trajectories of antisocial behavior in females Type de document : Texte imprimé et/ou numérique Auteurs : Nathalie FONTAINE, Auteur ; Edward D. BARKER, Auteur ; Richard E. TREMBLAY, Auteur ; Frank VITARO, Auteur ; René CARBONNEAU, Auteur Année de publication : 2009 Article en page(s) : p.363-385 Langues : Anglais (eng) Mots-clés : Antisocial-behavior developmental-trajectories females Index. décimale : PER Périodiques Résumé : Background: Knowledge on the onset and the development of antisocial behavior in females is limited, because most of the research in this domain is based on males.
Methods: We critically reviewed 46 empirical studies that examined developmental trajectories of antisocial behavior in females, notably to help determine whether or not an early-onset/life-course-persistent trajectory exists in females.
Results: The review suggested that antisocial behavior in females can follow different developmental trajectories (e.g., early-onset/life-course-persistent, childhood-limited, adolescence-limited, adolescence-delayed-onset, adulthood-onset). However, many of the studies reviewed were limited by factors such as the use of global measures of antisocial behavior, the identification of the trajectories based on threshold criteria, and the small sample sizes.
Conclusions: Future studies should take into account the shortcomings highlighted in this review. Such studies are needed to improve the understanding and prevention of the development of antisocial behavior in females.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2008.01949.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=723

TIESKENS, Auteur ; Pol A. C. VAN LIER, Auteur ; J. Marieke BUIL, Auteur ; Edward D. BARKER, Auteur Article en page(s) : p.791-799 Langues : Anglais (eng) Mots-clés : ALSPAC childhood victimization delinquency DNA methylation sensation-seeking Index. décimale : PER Périodiques Résumé : Heightened sensation-seeking is related to the development of delinquency. Moreover, sensation-seeking, or biological correlates of sensation-seeking, are suggested as factors linking victimization to delinquency. Here, we focused on epigenetic correlates of sensation-seeking. First, we identified DNA methylation (DNAm) patterns related to sensation-seeking. Second, we investigated the association between sensation-seeking related DNAm and the development of delinquency. Third, we examined whether victimization was related to sensation-seeking related DNAm and the development of delinquency. Participants (N = 905; 49% boys) came from the Avon Longitudinal Study of Parents and Children. DNAm was assessed at birth, age 7 and age 15-17. Sensation-seeking (self-reports) was assessed at age 11 and 14. Delinquency (self-reports) was assessed at age 17-19. Sensation-seeking epigenome-wide association study revealed that no probes reached the critical significance level. However, 20 differential methylated probes reached marginal significance. With these 20 suggestive sites, a sensation-seeking cumulative DNAm risk score was created. Results showed that this DNAm risk score at age 15-17 was related to delinquency at age 17-19. Moreover, an indirect effect of victimization to delinquency via DNAm was found. Sensation-seeking related DNAm is a potential biological correlate that can help to understand the development of delinquency, including how victimization might be associated with adolescent delinquency.

[article]
Titre : The adult outcome of childhood quasi-autism arising following extreme institutional deprivation Type de document : Texte imprimé et/ou numérique Auteurs : Maria RODRIGUEZ-PEREZ, Auteur ; Mark KENNEDY, Auteur ; Edward D. BARKER, Auteur ; Jana KREPPNER, Auteur ; Mireia SOLERDELCOLL, Auteur ; Edmund J.S. SONUGA-BARKE, Auteur Article en page(s) : p.1292-1302 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background Rutter and colleagues' seminal observation that extended early life exposure to extreme institutional deprivation can result in what he termed quasi-autism (QA), informed both our understanding of the effects of adversity on development and the nature of autism. Here we provide the first detailed analysis of the adult outcomes of the group of institutionally deprived-then-adopted children identified as displaying QA. Methods Twenty-six adult adoptees identified with QA in childhood (Childhood QA+) were compared to 75 adoptees who experienced extended institutional deprivation (>6 months) but no QA (Childhood QA?), and 116 adoptees exposed to Low/No institutional deprivation. The outcomes were child-to-adult developmental trajectories of neuro-developmental symptoms (autism, attention-deficit/hyperactivity disorder (ADHD), disinhibited social engagement (DSE) and cognitive impairment), adult functioning, life satisfaction and mental health. Results Childhood QA+ was associated with elevated and persistent trajectories of broad-based autism-related difficulties, ADHD and DSE symptoms and low IQ, as well as adult mental health difficulties and functional impairment, including high rates of low educational attainment and unemployment. Life satisfaction and self-esteem were unaffected. Autism-related communication problems, in particular, predicted negative adult outcomes. Childhood QA+ was still associated with poor outcomes even when ADHD, DSE and IQ were controlled. Conclusions Early and time-limited institutional deprivation has a critical impact on adult functioning, in part via its association with an early established and persistent variant of autism, especially related to communication difficulties. Apparent similarities and differences to non-deprivation related autism are discussed.
