Salivary DHEA-Cortisol Ratio Associations with Parental Maltreatment and Juvenile Incarcerated Male Psychopathy
Dehydroepiandrosterone (DHEA) and its ratio to cortisol moderate associations between maltreatment and psychopathology in male juvenile offenders Author: Kimonis ER, et al. (2019), Psychoneuroendocrinology. ABSTRACT This study examined whether DHEA and its ratio to cortisol moderated risk for psychopathology among incarcerated youth exposed to childhood maltreatment. Resistance to stress-related psychopathology under adversity was also examined in […]
Cortisol as a Target Mediator for Therapeutic Horseback Riding Effects in Youth with Autism Spectrum Disorder
Replication Pilot Trial of Therapeutic Horseback Riding and Cortisol Collection With Children on the Autism Spectrum Author: Zhaoxing P, et al. (2019), Frontiers. ABSTRACT We aimed to determine whether results of our prior randomized control trial [RCT; NCT02301195, (1)] of Therapeutic Horseback Riding (THR) for children and adolescents with autism spectrum disorder (ASD) could be replicated […]
Salivary Cortisol and DHEA are Inversely Correlated with Early Postnatal Growth and Blood Pressure in Extremely Preterm Children
Adrenal function links to early postnatal growth and blood pressure at age 6 in children born extremely preterm Author: Watterberg KL, et al. (2018), Pediatric Research. BACKGROUND: Low birth weight in term-born individuals correlates with adverse cardiometabolic outcomes; excess glucocorticoid exposure has been linked to these relationships. We hypothesized that cortisol and adrenal androgens would correlate […]
Low Salivary Alpha-Amylase Awakening Response Associated with Reduced Professional Efficacy
Reduced professional efficacy is associated with a blunted salivary alpha-amylase awakening response. Author: Landolt K, et al. (2018), Physiol Behav. ABSTRACT: The job demands-resources model (JD-R) has shown an ability to predict worker engagement and exhaustion, yet to our knowledge, research has not been conducted that assesses the JD-R model with physiological indicators of chronic stress […]
Cortisol Reactivity as a Predictor of Weight Gain Among Prenatally Drug-Exposed Girls
Cortisol reactivity and weight gain among adolescents who vary in prenatal drug exposure. Author: Armstrong B, et al. (2018), Pediatr Obes. OBJECTIVE: Low inhibitory control is linked with weight gain among youth. Inhibitory problems are associated with disruption to the hypothalamic-pituitary-adrenal axis cortisol response. Increased cortisol predicts appetite and weight gain (though may be gender specific). This study hypothesized that cortisol reactivity explains […]
HPA Axis Attunement May Serve a Bonding Function within Women’s Close Friendships
The Role of Co-Rumination and Adrenocortical Attunement in Young Women’s Close Friendships. Author: Rankin A, et al. (2018), Psychoneuroendocrinology. ABSTRACT: Attunement, or synchrony, of behavior and physiology has been well documented in family, mother-child, and romantic relationships. This study aimed to determine whether attunement of the hypothalamic-pituitary-adrenal (HPA) axis occurs in women’s close friendships, and […]
Salivary Stress Biomarkers May be a Useful Tool for Determining the Risk of Stress Maladaptation
Measuring Resilience to Operational Stress in Canadian Armed Forces Personnel. Author: Hellewll SC & Cernak I. (2018), J Trauma Stress. ABSTRACT Adaptability to stress is governed by innate resilience, comprised of complex neuroendocrine and immune mechanisms alongside inherited or learned behavioral traits. Based on their capacity to adapt, some people thrive in stressful situations, whereas […]
Effect of Service Dogs on the Salivary Cortisol Awakening Response in Veterans with PTSD
The Effect of a Service Dog on Salivary Cortisol Awakening Response in a Military Population with Posttraumatic Stress Disorder (PTSD) Author: Rodriguez KE, et al. (2018), Psychoneuroendocrinology ABSTRACT Recent studies suggest a therapeutic effect of psychiatric service dogs for military veterans with posttraumatic stress disorder (PTSD), but are limited by self-report biases. The current study […]
Salivary Cortisol Associated with Stress and Sleep Patterns in Military Men
Morning Cortisol Is Associated With Stress and Sleep in Elite Military Men: A Brief Report. Author: Hernández LM, et al. (2018), Mil Med INTRODUCTION: Accumulating evidence suggests that trends in salivary cortisol after awakening may be reliable biological predictors of morbidity and mortality. In a sample of elite military men, our lab recently established summary parameters of morning cortisol as well as […]
Salivary cytokine shows elevated communication and interaction fears may heighten neuroendocrine and inflammatory responses
Communication and social interaction anxiety enhance interleukin-1 beta and cortisol reactivity during high-stakes public speaking. Author: Auer BJ, et al (2018), Psychoneuroendocrinology BACKGROUND: Worry or fear related to speaking in front of others, or more broadly, communicating and interacting with others, is common. At elevated levels, however, it may contribute to heightened stress reactivity during acute […]
Social Context of Psychosocial Processes During Adolescent Development and the Psychobiology of the Stress Response.
Peer Networks, Psychobiology of Stress Response, and Adolescent Development Author: Kornienko, O, et al (2018), PLoS BACKGROUND: A consistent focus of research has been on understanding how social relationships shape the activity of the biological stress response system. Progress has been made in characterizing these dynamics at the level of the individual, but significantly less […]
Anticipation of fMRI leads to acute elevations in cortisol prior to scanning
Anticipatory stress associated with functional magnetic resonance imaging: Implications for psychosocial stress research. Author: Gossett EW, et al (2018), International journal of psychophysiology BACKGROUND: Stress tasks performed during functional magnetic resonance imaging (fMRI) elicit a relatively small cortisol response compared to stress tasks completed in a traditional behavioral laboratory, which may be due to apprehension […]
Measuring salivary cortisol levels in domestic canines
A systematic review and meta-analysis of salivary cortisol measurement in domestic canines Author: Cobb M, et al (2016), Domestic animal endocrinology Highlights Systematic review and meta- analysis determined reference range for salivary cortisol in dogs There is a large amount of intraindividual and interindividual variability Salivary cortisol concentrations might relate to subject, environment, or experimental […]
Evidence supports studying cortisol and DHEA in concert
Cortisol and DHEA in development and psychopathology Author: Karmin HS, et al (2017), Hormones and Behavior Dehydroepiandrosterone (DHEA) and cortisol are the most abundant hormones of the human fetal and adult adrenals released as end products of a tightly coordinated endocrine response to stress. Together, they mediate short- and long-term stress responses and enable physiological […]
Autonomic and Inflammatory Responses Moderated by Stress Appraisals and Affect
Coordination of cortisol response to social evaluative threat with autonomic and inflammatory responses is moderated by stress appraisals and affect Author: Laurent HK, et al (2016), Biol Psychol. Recent approaches to stress regulation have emphasized coordination among multiple biological systems. This study builds on evidence that hypothalamic-pituitary-adrenal (HPA) axis activity should be considered in coordination […]
