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. GUNNAR, Auteur Article en page(s) : p.1926-1936 Langues : Anglais (eng) Mots-clés : Adolescent  Adult  Brain/diagnostic imaging  Child  Humans  *Hydrocortisone  Magnetic Resonance Imaging  Minnesota  *Saliva  Stress, Psychological/diagnostic imaging  *adolescence  *brain function  *cortisol  *socially evaluative stress Index. décimale : PER Périodiques Résumé : Understanding individual differences in neural responses to stressful environments is an important avenue of research throughout development. 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.

Associations between multisystem stress reactivity and peer nominated aggression in early childhood vary by sex / Melissa J. HAGAN in Development and Psychopathology, 32-5 (December 2020)  

Public ISBD [article]  inDevelopment and Psychopathology > 32-5 (December 2020) . - p.1888-1898 Titre : Associations between multisystem stress reactivity and peer nominated aggression in early childhood vary by sex Type de document : Texte imprimé et/ou numérique Auteurs : Melissa J. HAGAN, Auteur ; Danielle S. ROUBINOV, Auteur ; W. Thomas BOYCE, Auteur ; Nicole R. BUSH, Auteur Article en page(s) : p.1888-1898 Langues : Anglais (eng) Mots-clés : *Aggression  Child  Child, Preschool  Female  Humans  Hydrocortisone  Hypothalamo-Hypophyseal System  Male  Pituitary-Adrenal System  *Saliva  Stress, Psychological  *cortisol reactivity  *early childhood  *peer-directed aggression  *sympathetic reactivity Index. décimale : PER Périodiques Résumé : There is emerging evidence that the development of problematic aggression in childhood may be associated with specific physiological stress response patterns, with both biological overactivation and underactivation implicated. This study tested associations between sex-specific patterns of stress responses across the sympathetic nervous system (SNS) and hypothalamic-pituitary-adrenal (HPA) axis and peer nominations of aggression among 271 kindergarten children (Mean age = 5.32 years; 52% Female; 44% White). Upon entry to kindergarten, children participated in a multidomain standardized stress paradigm. Changes in pre-ejection period (PEP) and salivary cortisol were assessed. On a separate day, children provided peer ratings of physical and relational aggression in a standardized interview. As expected, there was a significant three-way interaction between PEP, cortisol reactivity, and sex, but only for physical aggression. Among boys, cortisol reactivity was positively associated with physical aggression only for those with higher SNS reactivity. Findings suggest that for boys, asymmetrical and symmetrical HPA/SNS reactivity may be associated with lower and higher risk for peer-directed physical aggression, respectively. Understanding the complex associations between multisystem physiology, child sex and peer-directed aggression in early childhood may offer insight into individual differences underlying the emergence of behavioral dysregulation in early peer contexts.
