Cortisol and socioeconomic status in early childhood: A multidimensional assessment / Amanda R. TARULLO in Development and Psychopathology, 32-5 (December 2020)  

Public ISBD [article]  inDevelopment and Psychopathology > 32-5 (December 2020) . - p.1876-1887 Titre : Cortisol and socioeconomic status in early childhood: A multidimensional assessment Type de document : Texte imprimé et/ou numérique Auteurs : Amanda R. TARULLO, Auteur ; Charu T. TULADHAR, Auteur ; Katie KAO, Auteur ; Eleanor B. DRURY, Auteur ; Jerrold MEYER, Auteur Article en page(s) : p.1876-1887 Langues : Anglais (eng) Mots-clés : Child  Child, Preschool  Humans  *Hydrocortisone  Hypothalamo-Hypophyseal System  Infant  Pituitary-Adrenal System  *Saliva  Social Class  Stress, Psychological  *food insecurity  *hair cortisol  *salivary cortisol  *socioeconomic status  *stress Index. décimale : PER Périodiques Résumé : The hypothalamic-pituitary-adrenal (HPA) axis is sensitive to early life stress, with enduring consequences for biological stress vulnerability and health (Gunnar & Talge, 2008). Low socioeconomic status (SES) is associated with dysregulation of the stress hormone cortisol in early childhood. However, a mechanistic understanding of this association is lacking. Multidimensional assessment of both SES and cortisol is needed to characterize the intricate relations between SES and cortisol function in early childhood. We assessed parent-reported family income, parent education, occupational prestige, neighborhood risk, food insecurity, and household chaos for 12-month-old infants (N = 90) and 3.5-year-old children (N = 91). Hair cortisol concentration (HCC) was obtained from parent and child, indexing chronic biological stress, and diurnal salivary cortisol was measured in the children. Controlling for parent HCC, parent education uniquely predicted infant and child HCC and, in addition, neighborhood risk uniquely predicted infant HCC. Household chaos predicted bedtime salivary cortisol concentration (SCC) for both infants and children, and infant daily cortisol output. Food insecurity was associated with flattened cortisol slope in 3.5-year-old children. Parental sensitivity did not mediate relations between SES and cortisol. Results highlight the utility of SES measures that index unpredictable and unsafe contexts, such as neighborhood risk, food insecurity, and household chaos.

Differential brain activity as a function of social evaluative stress in early adolescence: Brain function and salivary cortisol / Max P. HERZBERG in Development and Psychopathology, 32-5 (December 2020)  

Public ISBD [article]  inDevelopment and Psychopathology > 32-5 (December 2020) . - p.1926-1936 Titre : Differential brain activity as a function of social evaluative stress in early adolescence: Brain function and salivary cortisol Type de document : Texte imprimé et/ou numérique Auteurs : Max P. HERZBERG, Auteur ; Ruskin H. HUNT, Auteur ; Kathleen M. THOMAS, Auteur ; Megan R.

These differences may be especially critical during adolescence, which is characterized by opportunities for healthy development and increased susceptibility to the development of psychopathology. While the neural correlates of the psychosocial stress response have been investigated in adults, these links have not been explored during development. Using a new task, the Minnesota Imaging Stress Test in Children (MISTiC), differences in activation are found in fusiform gyrus, superior frontal gyrus, insula, and anterior cingulate cortex when comparing a stressful math task to a nonstressful math task. The MISTiC task successfully elicits cortisol responses in a similar proportion of adolescents as in behavioral studies while collecting brain imaging data. Cortisol responders and nonresponders did not differ in their perceived stress level or behavioral performance during the task despite differences in neuroendocrine function. Future research will be able to leverage the MISTiC task for many purposes, including probing associations between individual differences in stress responses with environmental conditions, personality differences, and the development of psychopathology.

Elevated infant cortisol is necessary but not sufficient for transmission of environmental risk to infant social development: Cross-species evidence of mother-infant physiological social transmission / Rosemarie E. PERRY in Development and Psychopathology, 32-5 (December 2020)

A translational cross-species approach was used to examine stress-mediated pathways by which poverty-related adversity can influence infant social development. Findings from a longitudinal sample of low-income mother-infant dyads indicated that infant cortisol (CORT) on its own did not mediate relations between early-life scarcity-adversity exposure and later infant behavior in a mother-child interaction task. However, maternal CORT through infant CORT served as a mediating pathway, even when controlling for parenting behavior. Findings using a rodent "scarcity-adversity" model indicated that pharmacologically blocking pup corticosterone (CORT, rodent equivalent to cortisol) in the presence of a stressed mother causally prevented social transmission of scarcity-adversity effects on pup social behavior. Furthermore, pharmacologically increasing pup CORT without the mother present was not sufficient to disrupt pup social behavior. Integration of our cross-species results suggests that elevated infant CORT may be necessary, but without elevated caregiver CORT, may not be sufficient in mediating the effects of environmental adversity on development. These findings underscore the importance of considering infant stress physiology in relation to the broader social context, including caregiver stress physiology, in research and interventional efforts.

Enhancing diurnal cortisol regulation among young children adopted internationally: A randomized controlled trial of a parenting-based intervention / K. Lee RABY in Development and Psychopathology, 32-5 (December 2020)

In particular, internationally adopted children tend to have blunted diurnal declines compared to children raised in their birth families. The Attachment and Biobehavioral Catch-Up (ABC) intervention was developed to enhance young children's biological and behavioral regulation by promoting sensitive parenting. The current study used a randomized controlled trial to assess whether ABC improved the diurnal functioning of the HPA axis among 85 children who had been adopted internationally when they were between the ages of 4 and 33 months (M = 16.12). Prior to the intervention, there were no significant differences in diurnal cortisol production between children whose parents were randomly assigned to receive ABC and children whose parents were randomly assigned to receive a control intervention. After the intervention, children whose parents had received the ABC intervention exhibited steeper declines in cortisol levels throughout the day than children whose parents had received the control intervention. These results indicate that the ABC intervention is effective in enhancing a healthy pattern of diurnal HPA axis regulation for young children who have been adopted internationally.

Parenting matters: Parents can reduce or amplify children's anxiety and cortisol responses to acute stress / Anna M. PARENTEAU in Development and Psychopathology, 32-5 (December 2020)  

Public ISBD [article]  inDevelopment and Psychopathology > 32-5 (December 2020) . - p.1799-1809 Titre : Parenting matters: Parents can reduce or amplify children's anxiety and cortisol responses to acute stress Type de document : Texte imprimé et/ou numérique Auteurs : Anna M.

However, the parental characteristics that modulate the effectiveness of parents as stress buffers remain to be fully characterized. To address this gap, this study examined parental characteristics and behaviors that may explain variation in parents' ability to buffer cortisol responses to acute stress of 180 children (ages 9-11 years old, M = 9.9 years, SD = .58). Children were randomly assigned to either participate in a public speaking task, the Trier Social Stress Test - modified for children (TSST-M) or a control condition. Children in the TSST-M condition were randomly assigned to prepare for the public speaking task either with their parent (N = 59) or alone (N = 60), whereas 61 children were assigned to the control condition (no TSST-M). We found that parental education moderated the effect of condition on children's responses to acute stress. Children whose parents had lower levels of education exhibited reduced cortisol responses in the parent condition compared to the alone condition, showing a buffered pattern of reactivity. In contrast, children of parents with high levels of education displayed higher cortisol reactivity in the parent condition compared to the alone and control conditions. Parental education was also positively associated with higher levels of state anxiety within the parent condition. These results suggest that highly educated parents may emphasize performance over comfort, amplifying their children's state anxiety and cortisol responses to a public performance.
