This study examined recent stress exposure and effortful coping effects on salivary cortisol (sC) response patterns in preadolescent boys and girls (N = 121, Mage  = 10.60 years). Children were exposed to the Trier Social Stress Test (TSST) and one of two randomly assigned, post-TSST coping conditions: distraction and avoidance. Piecewise growth multilevel modeling did not link children's recent stressful life events or hair cortisol (hC) levels to sC reactivity, though each interacted with coping condition to predict sC recovery patterns...

The data combine objectively measured sleep and thrice-daily salivary cortisol collected from a 4-day diary study in a large Midwestern city with location data on all violent crimes recorded during the same time period for N = 82 children (Mage  = 14.90, range = 11.27-18.11). The primary empirical strategy uses a within-person design to measure the change in sleep and cortisol from the person's typical pattern on the night/day immediately following a local violent crime. On the night following a violent crime, children have later bedtimes...

OBJECTIVE: The precise mechanisms behind the development of hypertension in overweight or obese children are not yet completely understood. Alterations in hypothalamus-pituitary-adrenal axis activity may play a role. We aimed to investigate if there is an association between cortisol parameters and hypertension in overweight or obese children. METHODS: Random urine (n=180) and early-morning saliva samples (n=126) for assessment of cortisol and cortisone were collected from 1) hypertensive overweight children (n=50); 2) normotensive overweight children (n=145) and 3) normotensive non-overweight children (n=75)...

Children with congenital heart disease (CHD) have poorer neurodevelopmental and psychological outcomes. The mechanisms underlying this remain unclear. One mechanism could be that the stressful experience of cardiac surgery early in life influences long-term hypothalamic-pituitary-adrenal (HPA) axis regulation. Dysregulation of the HPA axis has been linked to poorer neurocognitive and psychological outcomes in other study populations. This case-control study aims to compare HPA-axis regulation (circadian rhythm and reactivity) using salivary cortisol in 3- to 5-year-olds with CHD who did and did not have cardiac surgery prior to 6 months of age...

INTRODUCTION: Inhaled corticosteroids (ICS) can interfere with the hypothalamic-pituitary-adrenal (HPA) axis and may lead to adrenal insufficiency, resulting in a decrease of cortisol production. Cortisol levels measured in scalp hair provide a marker for long-term cortisol exposure. Data regarding hair cortisol concentration (HCC) in asthmatic children with ICS therapy are scarce. The aim of this study is to compare HCC in asthmatic children under ICS treatment with a healthy control group...

The Trier Social Stress Test (TSST) is a well validated and widely used social stressor that has been shown to induce a 2-4 fold increase in cortisol, the biological output produced by the Hypothalamic-Pituitary-Adrenal (HPA) axis in humans. While studies have explored how modifications to the TSST influence stress responsivity, few studies have created a modified TSST appropriate for vulnerable youth that elicits a significant cortisol stress response. Thus, the current study sought to modify or adjust the TSST in a culturally sensitive way for a vulnerable sample of 14 year-old adolescents...

BACKGROUND: Mothers of children with food allergy have increased anxiety, which may be influenced by healthcare professionals' communication of risk. OBJECTIVE: To evaluate a brief psychological intervention for reducing anxiety in mothers of children with food allergy. METHODS: Two hundred mothers of children with food allergy were recruited from allergy clinics. A computer-generated randomization list was used to allocate participants to a single-session Cognitive Behavioural Therapy intervention including a risk communication module, or standard care...

Adrenal cortical hyperplasia manifests radiologically as the nonmalignant growth, or enlargement of the adrenal glands, specifically the cortex, although the cortex cannot be definitively identified by conventional imaging. Controlled by the pituitary gland, the adrenal cortex drives critical processes, such as cortisol, mineralocorticoid, and sex hormone production. Any disruption in the multiple enzymes and hormones involved in these pathways may cause serious or life-threatening symptoms, often associated with anatomical changes of the adrenal glands...

Early child maltreatment has been widely associated with the development of mental disorders in both childhood and adulthood. However, such association cannot be systematically established, as only few factors are observed regularly, such as high prevalence of comorbidities and externalized disorders. Similarly, the association between early abuse and cortisol secretion anomalies has been well-documented. Whereas early hypercortisolism followed by hypocortisolism was often described, the results proved inconsistent and at times contradictory...

BACKGROUND: In adults, hypothalamus-pituitary-adrenal (HPA) axis activity shows sexual dimorphism, and this is thought to be a mechanism underlying sex-specific disease incidence. Evidence is scarce on whether these sex differences are also present in childhood. In a meta-analysis, we recently found that basal (non-stimulated) cortisol in saliva and free cortisol in 24-h urine follow sex-specific patterns. We explored whether these findings could be extended with sex differences in HPA axis reactivity...

AIM: Maternal prenatal anxiety and stress (PNS) have been positively associated to physical health prob lems in offspring in the first year of life. Whether these associations are transient, persistent, or even progressive over time, is as yet unknown. The goal of this study is to investigate associations between late pregnancy PNS and child health from 18 months to age 6. METHODS: Mothers were recruited in late pregnancy, and had uncomplicated, singleton pregnancies without physical health problems...

Cognitive control is related to goal-directed self-regulation abilities, which is fundamental for human development. Conflict control includes the neural processes of conflict monitoring and conflict resolution. Testosterone and cortisol are essential hormones for the development of cognitive functions. However, there are no studies that have investigated the correlation of these two hormones with conflict control in preadolescents. In this study, we aimed to explore whether testosterone, cortisol, and testosterone/cortisol ratio worked differently for preadolescent's conflict control processes in varied conflict control tasks...

Over the past decades, southern Vietnam has been burdened by dioxins from contaminated herbicides sprayed during the Vietnam War. In a previous study, we found that dioxin exposure decreased levels of salivary dehydroepiandrosterone (DHEA), an adrenal androgen, in 3-year-old children. In present study, to assess the relationship between adrenal hormones disruption in lactating mothers and in children, we compared mother-child pairs from dioxin- and nondioxin-contaminated regions. In 2010 and 2011, mother-child pairs from a dioxin hotspot region (n=37) and a non-contaminated region (n=47) were recruited and donated breast milk and serum samples for dioxin and steroid hormones determination...

Literacy is a key factor in occupational success and social integration. However, an increasing number of children lack appropriate reading skills. There is growing evidence that dogs have positive effects on reading performance. We investigated the short-term effects of dogs on reading performance in 36 third-graders and monitored physiological parameters [heart rate (HR), heart rate variability (HRV), and salivary cortisol] as well as behavioral variables. Each child took part in two test sessions at the presence of a tutor, in one of which a dog and its handler were present...

Injury is the leading cause of death and disability in childhood. Injured children are at high risk for developing alterations in stress response systems and post-traumatic stress symptoms (PTSS) that may compromise long-term physical and psychological health. In a prospective, observational cohort study, we examined individual differences in, and correlates of, stress-reactivity of the hypothalamic-pituitary-adrenal axis (HPA; salivary cortisol) and autonomic nervous system (ANS; salivary alpha amylase, sAA) following pediatric injury...

BACKGROUND: Psychosocial stress during pregnancy has been proposed as a major contributor of glucocorticoid-mediated programming of the fetal hypothalamic-pituitary adrenal (HPA) axis, with later adverse health consequences. However, evidence linking maternal stress to maternal cortisol values during pregnancy is inconclusive. A possible explanation for this is that other maternal factors overshadow any potential effects of stress on cortisol levels. We studied a large cohort of pregnant women with extensive data on pregnancy characteristics to determine the respective contributions of biological, environmental and psychosocial stress factors to cortisol levels in pregnancy...

Theorists argue that parental reflective functioning (PRF) is activated in response to emotions, potentially supporting parenting sensitivity even when arousal is high. That is, when parents become emotionally reactive when interacting with their children, those who can use PRF to understand their children's mental states should be able to parent sensitively, which, in turn, should promote children's ability to understand their own mental states. We test this theory by examining whether, in the face of physiological reactivity, mothers' PRF inhibits one form of parenting insensitivity, overcontrol (OC), and whether this process in turn predicts children's RF...
