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

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.
