Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 62-1 (January 2021) . - p.19-27 Titre : Associations between developmental trajectories of peer victimization, hair cortisol, and depressive symptoms: a longitudinal study Type de document : Texte imprimé et/ou numérique Auteurs : Isabelle OUELLET-MORIN, Auteur ; Christina CANTAVE, Auteur ; Stéphane PAQUIN, Auteur ; Marie-Claude GEOFFROY, Auteur ; Mara BRENDGEN, Auteur ; Frank VITARO, Auteur ; Richard TREMBLAY, Auteur ; Michel BOIVIN, Auteur ; Sonia LUPIEN, Auteur ; Sylvana M. CÔTÉ, Auteur Article en page(s) : p.19-27 Langues : Anglais (eng) Mots-clés : HPA axis  Peer victimization  depression  hair cortisol  nonlinear models Index. décimale : PER Périodiques Résumé : BACKGROUND: Peer victimization has been associated with long-lasting risks for mental health. Prior research suggests that stress-related systems underlying adaptation to changing environments may be at play. To date, inconsistent findings have been reported for the hypothalamic-pituitary-adrenal (HPA) axis, and its end product cortisol. This study tested whether peer victimization was associated with hair cortisol concentrations (HCC), and whether this association varied according to sex, timing, and changes in exposure. We also examined whether peer victimization differentially predicted depressive symptoms according to HCC. METHODS: The sample comprised 556 adolescents (42.0%; 231 males) who provided hair for cortisol measurement at 17 years of age. Peer victimization was reported at seven occasions between the ages of 6 and 15 years. RESULTS: Peer victimization was nonlinearly associated with HCC for boys only, whereas changes in peer victimization were related to HCC for boys and girls. Peer victimization predicted more depressive symptoms for all participants, except those with lower HCC. CONCLUSIONS: Our findings provide further support for persistent dysregulation of the HPA axis following exposure to chronic adversity, of which the expression may change according to sex and the severity of victimization.

Concurrent and prospective associations between family socioeconomic status, social support and salivary diurnal and hair cortisol in adolescence / Mara BRENDGEN ; Sonia LUPIEN ; Ginette DIONNE ; Frank VITARO ; Michel BOIVIN ; Isabelle OUELLET-MORIN in Journal of Child Psychology and Psychiatry, 65-3 (March 2023)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 65-3 (March 2023) . - p.298-307 Titre : Concurrent and prospective associations between family socioeconomic status, social support and salivary diurnal and hair cortisol in adolescence Type de document : Texte imprimé et/ou numérique Auteurs : Mara BRENDGEN, Auteur ; Sonia LUPIEN, Auteur ; Ginette DIONNE, Auteur ; Frank VITARO, Auteur ; Michel BOIVIN, Auteur ; Isabelle OUELLET-MORIN, Auteur Article en page(s) : p.298-307 Index. décimale : PER Périodiques Résumé : Background Exposure to socioeconomic adversity is hypothesized to impact hypothalamic?pituitary?adrenal (HPA) axis activity and cortisol secretion, but existing evidence is inconsistent. Yet, few studies have investigated this association using a developmental approach that considers potential protective contextual factors. This study examined the role of stability and changes in family socioeconomic status (SES) in the prediction of multiple cortisol indicators and tested whether social support moderated these associations. Methods Participants were part of a population-based sample of twin pairs recruited at birth. Family SES was assessed in early childhood (ages 0?5) and mid-adolescence (age 14). Social support was assessed at ages 14 and 19. Diurnal cortisol (n?=?569) was measured at age 14 at awakening, 30?min later, in the afternoon and evening over four non-consecutive days. Hair cortisol concentration (HCC, n?=?704) was measured at age 19. All data were collected before the pandemic and multilevel regression models were conducted to account for the nested data structure. Results Youth exposed to lower family SES levels in childhood and mid-adolescence had a flatter diurnal slope and higher HCC compared with those who experienced upward socioeconomic mobility in mid-adolescence. Contrastingly, mid-adolescence SES showed no association with the diurnal slope or HCC for youth from higher-SES households in early childhood. Moreover, youth raised in higher-SES families in early childhood had a higher CAR in mid-adolescence if they reported greater social support in mid-adolescence. Social support also moderated the SES-cortisol association in mid-adolescence, with higher-SES youth showing higher awakening cortisol secretion when reporting more social support. Conclusions Our findings support the hypothesis that early socioeconomic adversity sensitizes HPA axis activity to later socioeconomic disadvantage, which may bear consequences for socioemotional and behavioral functioning.

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)

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.
