5-HTTLPR variation may influence the impact of early adversity on HPA-axis regulation
Individual Differences in Early Adolescents’ Latent Trait Cortisol: Interaction of Early Adversity and 5-HTTLPR. Author: Chen FR, et al. (2017), Biol Psychol. The present study aimed to examine the interaction of 5-HTTLPR and early adversity on trait-like levels of cortisol. A community sample of 117 early adolescent girls (M age=12.39years) provided DNA samples for 5-HTTLPR […]
Disorganized attachment in infants associated with elevated salivary CRP
Increased levels of inflammation among infants with disorganized histories of attachment Author: Measelle JR, et al. (2017), Behavioural Brain Research Early life adversity is associated with adult elevations of inflammatory markers such as circulating levels of C-reactive protein (CRP). Few studies have examined inflammation levels during infancy nor the associations between sources of adversity and […]
Latent Trait Cortisol level reflects accumulation of both distal and recent forms of stress
Individual differences in early adolescents’ latent trait cortisol (LTC): Relation to recent acute and chronic stress. Author: Stroud CB, et al (2016), Psychoneuroendocrinology Research suggests that environmental stress contributes to health by altering the regulation of the hypothalamic pituitary adrenal (HPA) axis. Recent evidence indicates that early life stress alters trait indicators of HPA axis […]
Salivary cortisol and the effects of child care on development in high & low risk contexts
Child Care and Cortisol Across Infancy and Toddlerhood: Poverty, Peers, and Developmental Timing Author: Berry, et al (2016), Family Relations Evidence suggests that relations between child care and children’s development—behaviorally and physiologically—likely differ between children from high- versus low-risk contexts. Using 1,155 participant data from the Family Life Project, the authors tested (a) whether within- […]
Review: How negative parent-child relationships affect the biological stress system
Family relations, stress, and vulnerability: Biobehavioral implications for prevention and practice Author: Ha, et al (2016), Family Relations Developmental psychobiology research supports the hypothesis that individual differences in biological stress systems that are sensitive to environmental experiences are associated with individual adjustment problems. Negative social experiences, especially in family contexts, contribute to the dysregulation of […]
Early adversity contributes to lower latent trait salivary cortisol (LTC) levels in adolescence
Individual differences in early adolescents’ latent trait cortisol (LTC): Relation to early adversity Author: Stroud CB, et al (2016), Developmental Psychobiology Substantial evidence suggests that youth who experience early adversity exhibit alterations in hypothalamic pituitary adrenal (HPA) axis functioning, thereby increasing risk for negative health outcomes. However, few studies have explored whether early adversity alters […]
