Allostasis model facilitates understanding race differences in the diurnal cortisol rhythm / Martie L. SKINNER in Development and Psychopathology, 23-4 (November 2011)  

Public ISBD [article]  inDevelopment and Psychopathology > 23-4 (November 2011) . - p.1167-1186 Titre : Allostasis model facilitates understanding race differences in the diurnal cortisol rhythm Type de document : Texte imprimé et/ou numérique Auteurs : Martie L. SKINNER, Auteur ; Elizabeth SHIRTCLIFF, Auteur ; Kevin P. HAGGERTY, Auteur ; Christopher COE, Auteur ; Richard F. CATALANO, Auteur Année de publication : 2011 Article en page(s) : p.1167-1186 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The concept of allostasis suggests that greater cumulative stress burden can influence stress-responsive physiology. Dysregulation of allostatic mediators, including the hypothalamic–pituitary–adrenal (HPA) axis, is thought to precede many other signs of age-related pathology as the persistent burden of stressors accumulates over the individual's life span. We predicted that even in young adulthood, HPA regulation would differ between Blacks and Whites, reflecting, in part, higher rates of stressor exposure and greater potential for stressors to “get under the skin.” We examined whether stressor exposure, including experiences with racism and discrimination, explained race differences in waking cortisol and the diurnal rhythm. We also examined whether HPA functioning was associated with mental health outcomes previously linked to cortisol. Salivary cortisol was assayed in 275 young adults (127 Blacks, 148 Whites, 19 to 22 years old), four times a day across 3 days. Hierarchical linear models revealed flatter slopes for Blacks, reflecting significantly lower waking and higher bedtime cortisol levels compared to Whites. Associations of HPA functioning with stressors were typically more robust for Whites such that more stress exposure created an HPA profile that resembled that of Black young adults. For Blacks, greater stressor exposure did not further impact HPA functioning, or, when significant, was often associated with higher cortisol levels. Across both races, flatter slopes generally indicated greater HPA dysregulation and were associated with poor mental health outcomes. These differential effects were more robust for Whites. These findings support an allostatic model in which social contextual factors influence normal biorhythms, even as early as young adulthood.

Time-varying effects of families and peers on adolescent marijuana use: Person–environment interactions across development / Marina EPSTEIN in Development and Psychopathology, 29-3 (August 2017)  

Public ISBD [article]  inDevelopment and Psychopathology > 29-3 (August 2017) . - p.887-900 Titre : Time-varying effects of families and peers on adolescent marijuana use: Person–environment interactions across development Type de document : Texte imprimé et/ou numérique Auteurs : Marina EPSTEIN, Auteur ; Karl G. HILL, Auteur ; Stephanie S. ROE, Auteur ; Jennifer A. BAILEY, Auteur ; William G. IACONO, Auteur ; Matt MCGUE, Auteur ; Allison KRISTMAN-VALENTE, Auteur ; Richard F. CATALANO, Auteur ; Kevin P. HAGGERTY, Auteur Article en page(s) : p.887-900 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Studies have demonstrated that the effects of two well-known predictors of adolescent substance use, family monitoring and antisocial peers, are not static but change over the course of adolescence. Moreover, these effects may differ for different groups of youth. The current study uses time-varying effect modeling to examine the changes in the association between family monitoring and antisocial peers and marijuana use from ages 11 to 19, and to compare these associations by gender and levels of behavioral disinhibition. Data are drawn from the Raising Healthy Children study, a longitudinal panel of 1,040 youth. The strength of association between family monitoring and antisocial peers and marijuana use was mostly steady over adolescence, and was greater for girls than for boys. Differences in the strength of the association were also evident by levels of behavioral disinhibition: youth with lower levels of disinhibition were more susceptible to the influence of parents and peers. Stronger influence of family monitoring on girls and less disinhibited youth was most evident in middle adolescence, whereas the stronger effect of antisocial peers was significant during middle and late adolescence. Implications for the timing and targeting of marijuana preventive interventions are discussed.
