Diurnal cortisol rhythms in youth from risky families: Effects of cumulative risk exposure and variation in the serotonin transporter linked polymorphic region gene / Cynthia J. WILLNER in Development and Psychopathology, 26-4 (Part 1) (November 2014)  

Public ISBD [article]  inDevelopment and Psychopathology > 26-4 (Part 1) (November 2014) . - p.999-1019 Titre : Diurnal cortisol rhythms in youth from risky families: Effects of cumulative risk exposure and variation in the serotonin transporter linked polymorphic region gene Type de document : texte imprimé Auteurs : Cynthia J. WILLNER, Auteur ; Pamela A. MORRIS, Auteur ; Dana Charles MCCOY, Auteur ; Emma K. ADAM, Auteur Année de publication : 2014 Article en page(s) : p.999-1019 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Building on research on cumulative risk and psychopathology, this study examines how cumulative risk exposure is associated with altered diurnal cortisol rhythms in an ethnically diverse, low-income sample of youth. In addition, consistent with a diathesis-stress perspective, this study explores whether the effect of environmental risk is moderated by allelic variation in the serotonin transporter linked polymorphic region (5-HTTLPR) gene. Results show that youth with greater cumulative risk exposure had flatter diurnal cortisol slopes, regardless of 5-HTTLPR genotype. However, the association of cumulative risk with average cortisol output (area under the curve [AUC]) was moderated by the 5-HTTLPR genotype. Among youth homozygous for the long allele, greater cumulative risk exposure was associated with lower cortisol AUC, driven by significant reductions in cortisol levels at waking. In contrast, there was a trend-level association between greater cumulative risk and higher cortisol AUC among youth carrying the short allele, driven by a trend-level increase in bedtime cortisol levels. Findings are discussed with regard to the relevance of dysregulated diurnal cortisol rhythms for the development of psychopathology and the implications of genetically mediated differences in psychophysiological adaptations to stress.

The acute effects of community violence on young children's regulatory, behavioral, and developmental outcomes in a low-income urban sample in Brazil / Dana Charles MCCOY in Journal of Child Psychology and Psychiatry, 65-5 (May 2024)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 65-5 (May 2024) . - p.620-630 Titre : The acute effects of community violence on young children's regulatory, behavioral, and developmental outcomes in a low-income urban sample in Brazil Type de document : texte imprimé Auteurs : Dana Charles MCCOY, Auteur ; Marta DORMAL, Auteur ; Jorge CUARTAS, Auteur ; Angélica CARREIRA DOS SANTOS, Auteur ; Günther FINK, Auteur ; Alexandra BRENTANI, Auteur Article en page(s) : p.620-630 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background Existing research on the impacts of adversity on young children's psychological well-being has largely focused on household-level risk factors using observational methods in high-income countries. This study leverages natural variation in the timing and location of community homicides to estimate their acute effects on the regulatory, behavioral, and developmental outcomes of Brazilian 3-year-olds. Methods We compared the outcomes of children who were assessed soon after a recent neighborhood homicide to those of children from the same residential neighborhoods who had not recently experienced community violence. Our sample included 3,241 3-year-olds (Mage = 41.05 months; 53% female; 45% caregiver education less than middle school; 26% receiving a public assistance program) from seven neighborhoods in São Paulo, Brazil. Child outcome measures included parent reports of effortful control and behavior problems as well as direct assessments of children's developmental (cognitive, language, and motor) skills. Community homicides were measured using police records. Results Recent exposure to community homicides was associated with lower effortful control, higher behavior problems, and lower overall developmental performance for children (d = .05-.20 standard deviations; p = ns - <.001). Effects were consistent across subgroups based on sociodemographic characteristics and environmental supports, but generally largest when community violence exposure was geographically proximal (within 600 m of home) and recent (within 2 weeks prior to assessment). Conclusions Results highlight the pervasive effects that community violence can have on young children as well as the need to expand support to mitigate these effects and prevent inequities early in life.
