Salivary DHEA-S, Cortisol show emotional & neuroendocrine response in relation to Telomere Length
Telomere Length and Procedural Justice Predict Stress Reactivity Responses to Unfair Outcomes in African Americans. Author: Lucas T, et al. (2017), Psychoneuroendocrinology Highlights TL predicts how psychosocial factors influence acute stress responses. Stress resiliency reflects telomere and procedural justice congruence. Considering TL as a predictor can advance understanding of racial health disparities. View Abstract Keywords: […]
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 […]
HPA axis and SNS reactivity moderate relationship between IPV and infant internalizing behavior
Exposure to intimate partner violence in utero and infant internalizing behaviors: Moderation by salivary cortisol-alpha amylase asymmetry. Author: Martinez-Torteya C, et al. (2017), Early Human Development Guided by the main tenets of contemporary models of the developmental origins of health and disease, this study evaluated whether individual differences in reactivity of the hypothalamic-pituitary-adrenal (HPA) axis […]
Reproducibility of salivary cortisol measurement across established-qualified laboratories
Measurement of cortisol in saliva: a comparison of measurement error within and between international academic‑research laboratories. Author: Calvi JL, et al. (2017), BMC Research Notes 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 […]
Traumatic childhood injuries related to changes in stress reactivity
Altered Stress System Reactivity After Pediatric Injury: Relation with Post-Traumatic Stress Symptoms Author: Ewing-Cobbs, et al. (2017), Psychoneuroendocrinology Research Article Highlights; HPA and ANS stress systems were dysregulated after nonintentional pediatric injury. HPA and ANS activity and regulation varied with age at injury and type of injury. Cortisol reactivity to social stress was attenuated after […]
Childhood maltreatment affects cortisol and alpha-amylase stress reactivity
Patterns of cortisol and alpha-amylase reactivity to psychosocial stress in maltreated women Author: Mielock AS, et al. (2017), Journal of Affective Disorders BACKGROUND: Childhood maltreatment can trigger enduring changes in major stress response systems, particularly in the context of major depressive disorder (MDD). However, the relative impact of maltreatment versus MDD on hypothalamic-pituitary-adrenal axis and […]
Differences in HPA axis activity are a function of age and cumulative risk
Individual differences in the activity of the hypothalamic pituitary adrenal axis: Relations to age and cumulative risk in early childhood Author: Holochwost SJ, et al. (2017), Psychoneuroendocrinology This study examined individual differences in the function of the hypothalamic-pituitary-adrenal (HPA) axis with regard to age and cumulative risk during challenging laboratory tasks administered at 6, 12, […]
Adolescent appraisal of interparental conflict is reflected by stress reactivity
Adolescent conflict appraisals moderate the link between marital conflict and physiological stress reactivity Author: Lucas-Thompson RG, et al. (2017), Journal of Research on Adolescence The goal of this study was to advance understanding of how adolescent conflict appraisals contribute uniquely, and in combination with interparental conflict behavior, to individual differences in adolescent physiological reactivity. Saliva […]
Variation in salivary cortisol and alpha-amylase rhythms over 24 months
Long-term stability of diurnal salivary cortisol and alpha-amylase secretion patterns Author: Skoluda N, et al. (2017), Physiology & Behavio This study aimed to investigate long-term stability and variability of diurnal cortisol and alpha-amylase patterns. Diurnal cortisol and alpha-amylase secretion patterns were assessed on a single workday with three waves of measurement across a total time […]
Temperament predicts salivary cortisol and alpha-amylase in BASE jumpers
Stress reactivity and personality in extreme sport athletes: The psychobiology of BASE jumpers Author: Monasterio E, et al. (2016), Physiology & Behavior This is the first report of the psychobiology of stress in BASE jumpers, one of the most dangerous forms of extreme sport. We tested the hypotheses that indicators of emotional style (temperament) predict […]
Salivary Cortisol variability is influenced by social characteristics of owner and dog
Psychobiological Factors Affecting Cortisol Variability in Human-Dog Dyads Author: Schöberl I, et al. (2017), PLOS One Stress responses within dyads are modulated by interactions such as mutual emotional support and conflict. We investigated dyadic psychobiological factors influencing intra-individual cortisol variability in response to different challenging situations by testing 132 owners and their dogs in a […]
Individual responses to psychosocial stress are influenced by a neural mechanism
Prefrontal Cortex Activity Is Associated with Biobehavioral Components of the Stress Response Author: Wheelock MD, et al (2016), Frontiers in Human Neuroscience. Contemporary theory suggests that prefrontal cortex (PFC) function is associated with individual variability in the psychobiology of the stress response. Advancing our understanding of this complex biobehavioral pathway has potential to provide insight […]
The stress response to perceived discrimination as indicated by salivary measures
Perceived Discrimination, Racial Identity, and Multisystem Stress Response to Social Evaluative Threat among African American Men and Women Author: Lucas T, et al (2016), Psychosomatic Medicine. OBJECTIVES: Understanding individual differences in the psychobiology of the stress response is critical to grasping how psychosocial factors contribute to racial and ethnic health disparities. However, the ways in […]
Study demonstrates combined effects of salivary cortisol & DHEA-S in predicting depressive symptoms
Concurrent and prospective associations between HPA axis activity and depression symptoms in newlywed women Author: Ge F, et al (2016), Psychoneuroendocrinology. We investigated the extent to which individual differences in activity of the hypothalamic pituitary adrenal axis (HPA) are associated with depressive symptoms among newlywed couples. Participants were 218 couples (M age 28.4 years; 94% […]
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 […]
