The phenotypic associations and gene-environment underpinnings of socioeconomic status and diurnal cortisol secretion in adolescence / Christina Y. CANTAVE in Development and Psychopathology, 35-3 (August 2023)

Titre : The phenotypic associations and gene-environment underpinnings of socioeconomic status and diurnal cortisol secretion in adolescence Type de document : Texte imprimé et/ou numérique Auteurs : Christina Y. CANTAVE, Auteur ; Mara BRENDGEN, Auteur ; Stéphane PAQUIN, Auteur ; Sonia LUPIEN, Auteur ; Ginette DIONNE, Auteur ; Frank VITARO, Auteur ; Michel BOIVIN, Auteur ; Isabelle OUELLET-MORIN, Auteur Article en page(s) : p.1119-1129 Langues : Anglais (eng) Mots-clés : cortisol gene-environment interactions heritability HPA-axis socioeconomic status Index. décimale : PER Périodiques Résumé : While converging evidence suggests that both environmental and genetic factors underlie variations in diurnal cortisol, the extent to which these sources of influence vary according to socioeconomic status (SES) has seldom been investigated, particularly in adolescence. To investigate whether a distinct genetic and environmental contribution to youth?s diurnal cortisol secretion emerges according to family SES and whether the timing of these experiences matters. Participants were 592 twin pairs, who mostly came from middle-income and intact families and for whom SES was measured in childhood and adolescence. Diurnal cortisol was assessed at age 14 at awakening, 30 min later, in the afternoon and evening over four nonconsecutive days. SES-cortisol phenotypic associations were specific to the adolescence period. Specifically, higher awakening cortisol levels were detected in wealthier backgrounds, whereas higher cortisol awakening response (CAR) and diurnal changes were present at both ends of the SES continuum. Moreover, smaller genetic contributions emerged for awakening cortisol in youth from poorer compared to wealthier backgrounds. The results suggest that the relative contribution of inherited factors to awakening cortisol secretion may be enhanced or suppressed depending on the socio-family context, which may help to decipher the mechanisms underlying later adjustment.

Titre : Annual Research Review: Resilience – clinical implications Type de document : Texte imprimé et/ou numérique Auteurs : Michael RUTTER, Auteur Article en page(s) : p.474-487 Mots-clés : Stress inoculation planning school experiences self-control self-reflection turning points gene-environment interactions social relationships Index. décimale : PER Périodiques Résumé : Background: It is a universal finding that there is huge heterogeneity in people’s responses to all kinds of stress and adversity. Resilience is an interactive phenomenon that is inferred from findings indicating that some individuals have a relatively good outcome despite having experienced serious adversities. Methods: Resilience can only be inferred if there has been testing of environmental mediation of risks and quantification of the degree of risk. The use of ‘natural experiments’ to test environmental mediation is briefly discussed. The literature is then reviewed on features associated with resilience in terms of (a) those that are neutral or risky in the absence of the risk experience (such as adoption); (b) brief exposure to risks and inoculation effects; (c) mental features (such as planning, self-regulation or a sense of personal agency); (d) features that foster those mental features; (e) turning point effects; (f) gene-environment interactions; (g) social relationships and promotive effects; and (h) the biology of resilience. Results: Clinical implications are considered with respect to (a) conceptual implications; (b) prevention; and (c) treatment. Conclusion: Resilience findings do not translate into a clear programme of prevention and treatment, but they do provide numerous leads that focus on the dynamic view of what may be involved in overcoming seriously adverse experiences.
