Sunhye Bai, Theodore F Robles, Bridget M Reynolds, Rena L Repetti
This study examined the within-and between-person associations between daily negative events - peer problems, academic problems and interparental conflict - and diurnal cortisol in school-age children. Salivary cortisol levels were assessed four times per day (at wakeup, 30min later, just before dinner and at bedtime) on eight days in 47 youths ages 8-13 years old (60% female; M age=11.28, SD=1.50). The relative contributions of within- and between-person variances in each stressor were estimated in models predicting same-day diurnal cortisol slope, same-day bedtime cortisol, and next morning wakeup cortisol...

Extensive literature suggests that adverse experiences in early childhood may deleteriously impact later health. These effects are thought to be related to the impact of persistent or chronic stress on various biological processes, mediated by dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, and ultimately irregularities in cortisol levels. Ameliorating persistent stress in young children requires accurately measuring the chronicity of physiologic stress, which is difficult in young children because of unreliable self-report and the burden and inaccuracy associated with using invasive acute-stress biomeasures...

Families of preschoolers participated in two dyadic home visits, once with mother (56 dyads) and once with father (59 dyads). Each member of the dyad provided three cortisol samples and participated in several interaction tasks that were behaviorally coded. Approximately half of the children had been diagnosed with autism spectrum disorders (ASD), whereas half were typically developing (TD). In a multilevel model, father's cortisol level at each timepoint predicted child cortisol. Father-child linkage was stronger in dyads that showed less reciprocity, in which fathers showed less sensitivity, and in which children showed less self-regulation and more withdrawal...

Paraneoplastic syndromes are rare disorders that are triggered by an altered immune system response to neoplasm. Paraneoplastic syndromes may be the first or the most prominent manifestations of cancer. Wilm's tumor is the most frequent pediatric renal malignancy and usually presents with abdominal mass. Unusual presentations like acquired von Willebrand disease, sudden death due to pulmonary embolism and Cushing syndrome have been described in the literature. Cushing syndrome, as the presenting symptom of a malignant renal tumor in children, is a very rare entity...

Prenatal programming of hypothalamic-pituitary-adrenal (HPA) axis activity has long term implications for offspring health. Biological mechanisms underlying programming of the offspring HPA axis are poorly understood. We hypothesised that altered maternal metabolism including higher maternal obesity, glucose and lipids are novel programming factors for altered offspring HPA axis activity. Salivary cortisol levels were measured in 54 children aged 3-5 years under experimental conditions (before and after a delay of self-gratification test)...

This study examined children's (N = 79; 9-10 years) and adolescents' (N = 82; 15-16 years) ability to regulate their emotion expressions of anxiety as they completed a modified version of the Trier Social Stress Test for Children (TSST-C). Approximately half in each age group were internationally adopted from institutional care (N = 79) and half were non-adopted, age-matched peers (N = 82). Institutional care was viewed as a form of early life stress. Coders who were reliable and blind to group status watched videos of the session to assess anxiety expressions using the Child and Adolescent Stress and Emotion Scale developed for this study...

BACKGROUND: Adiponectin is an anti-inflammatory, insulin-sensitizing and energy-regulating adipocytokine. Consequently, the link between psychosocial stress and inflammatory diseases like the metabolic syndrome might be partially explained by lower adiponectin levels in stress. Nevertheless, the stress-adiponectin association has seldom been tested and no clarity exists about the directionality. METHODS: In the Belgian ChiBS study, serum adiponectin and stress levels were measured in 348 children (5-10y) at baseline and in 168 of them after 2-year follow-up...

We investigated circadian mother-child adrenocortical attunement in the context of a maternal history of childhood abuse (HoA). Mothers were screened after birth using the Childhood Trauma Questionnaire. Women reporting moderate or severe abuse formed the HoA group (n = 37; HoAG) and were compared with a non-maltreated comparison group (n = 45; CG). Three years later, cortisol awakening response (CAR) and diurnal slope (DSL) were assessed. Mother-child interaction was coded using the Emotional Availability Scales at 12 months of age...

The present study examined associations among parent and child reports of youth's stressful life events, perceived stress, and biological measures of stress activity (i.e., cortisol and cardiovascular activity). Examining these aspects of youth stress presents several challenges. Unlike adult studies of individual differences in which information regarding stressful life events, perceptions of events, and biological activity are gathered from one individual, assessment of individual differences among children usually involves other informants (e...

Neurological disorders can be exacerbated in an offspring that is exposed to stress prenatally. This study is aimed to investigate the severity of febrile seizures (FS) in the offspring under 2years old that were prenatally stressed. In this study, 158 children below 2years old with FS were selected. Information about convulsion including seizure lasting, recurrence of seizure, age of the first seizure and type of FS was gathered. Blood samples were obtained from the offspring to measure the cortisol blood levels...

OBJECTIVE: Cortisol, the end product of the hypothalamic-pituitary-adrenal axis, plays an important role in modulating sleep. Yet, studies investigating the association between diurnal cortisol rhythm and sleep patterns in young children are scarce. We tested the hypothesis that the diurnal cortisol rhythm is associated with shorter sleep duration and more sleep problems across early childhood. METHODS: This study was embedded in Generation R, a population-based cohort from fetal life onward...

INTRODUCTION: This observational study explores potential links between obese children's cortisol, and parental mental state, family functioning, and the children's symptoms of anxiety and depression. MATERIAL AND METHODS: A non-random sample of 104 obese children (55 boys), mean age 10.9 years (standard deviation 1.76), was recruited from a childhood obesity clinic. Obesity was defined as body mass index above the 95th age- and gender-specific percentiles. Neuroendocrine biomarkers were measured...

Aggression jeopardizes positive development in children and predicts social and academic maladjustment in school. The present study determined the relationships among anger dysregulation (a marker of emotion regulation), cortisol activity (a biomarker of stress), and peer-nominated aggression in typically developing children in their everyday classroom setting (N = 151, Mean age = 10.86, SD =.74). Salivary cortisol was collected at 09:15, 11:45, and 14:45 hr across 4 consecutive days. Children provided self-reports of anger regulation; peers reported proactive and reactive aggressive behaviors...

BACKGROUND: Animal models show that prenatal bisphenol A (BPA) exposure leads to sexually dimorphic disruption of the neuroendocrine system in offspring, including the hypothalamic-pituitary-adrenal (HPA) neuroendocrine system, but human data are lacking. In humans, prenatal BPA exposure is associated with sex-specific behavioural problems in children, and HPA axis dysregulation may be a biological mechanism. The objective of the current study was to examine sex differences in associations between prenatal maternal urinary BPA concentration and HPA axis function in 3 month old infants...

BACKGROUND: With the paucity of available literature correlating genetic mutation and response to treatment, we aimed to study the genetic makeup of children with growth hormone (GH) deficiency in Western India and correlate the mutation with auxology and response to GH treatment at end of 1 year. METHODS: Fifty-three (31 boys and 22 girls) children with severe short stature (height for age z-score <-3) and failed GH stimulation test were studied. Those having concomitant thyroid hormone or cortisol deficiencies were appropriately replaced prior to starting GH treatment...

Background: The transition to child care is a challenging time in a child's life and leads to elevated levels of cortisol. These elevations may be influenced by the quality of the mother-child relationship. However, remarkably little is known about cortisol production in response to the beginning of child care among children-at-risk such as children with an immigrant background. However, attending kindergarten or any other child day-care institution can for example have a compensating effect on potential language deficits thus improving the educational opportunities of these children...

BACKGROUND: Preterm birth has been associated with altered hypothalamic-pituitary-adrenal (HPA-) axis activity as well as cardiometabolic diseases and neurodevelopmental impairments later in life. We assessed cortisol from term age to age 8 y in children born preterm, to explore the development of HPA-axis activity in association with intrauterine and early-postnatal growth until 6 mo. corrected age. METHODS: In 152 children born at a gestational age ≤32 wks. and/or with a birth weight ≤1,500g, random serum cortisol was assessed at term age (n=150), 3 mo...

OBJECTIVE: Carriers of congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD) demonstrate increased secretion of cortisol precursors following ACTH stimulation, suggestive of impaired cortisol production and compensatory increases in hypothalamic corticotropin-releasing hormone (CRH) secretion. Both cortisol and CRH have behavioral effects, and hypothalamic CRH hypersecretion has been associated with chronic states of anxiety and depression. We performed an endocrinologic and psychological evaluation in carriers of 21-OHD and matched control subjects...

OBJECTIVE: Although parental presence during anesthesia induction is suggested to diminish operative stress level in children, there have been conflicting results about this strategy. The aim of this study was to evaluate the effects of maternal presence during induction on operative stress level in children who had tonsillectomy and/or adenoidectomy by determining the salivary cortisol levels. DESIGN: Non-randomized clinical study. SETTING: Preoperative and postoperative recovery rooms, operating room...
