Cortisol diurnal

Lisa R Starr, Kimberly Dienes, Y Irina Li, Zoey A Shaw
Chronic stress exposure has been shown to alter hypothalamic-pituitary-adrenal (HPA) axis functioning, which may mediate its effects on psychopathology and negative health outcomes. The nature of the chronic stress-HPA axis dysregulation is unclear and individuals likely vary in the extent to and manner in which indices of HPA axis regulation, such as diurnal cortisol slope, are influenced by chronic stress. We examined whether HPA-axis-linked genetic variation moderates the association between chronic stress and diurnal cortisol slope, and potential implications for mood and fatigue (possible manifestations of negative clinical outcomes)...

Daily life stress is an omnipresent phenomenon in modern society. Research has linked prolonged activation of the hypothalamic-pituitary-adrenal axis to psychiatric and somatic diseases. Everyday stressors substantially contribute to these health risks. Despite the notion that the physiological stress response is highly dependent on concurrent psychological processes, investigations associating diurnal cortisol levels with subjective experience have primarily focused on affective states. The impact of everyday cognitive processes including thought content has been largely neglected...

OBJECTIVE: Mindfulness-based interventions (MBI) have been related with improved job satisfaction, wellbeing, health, and reduced workplace stress with employees. However, until now, synthesis of the evidence of the effect of MBIs on physiological indices associated with stress and ill-health has been lacking. Therefore the current systematic review aimed to synthesise the literature from employee samples to provide guidance for future investigations in terms of which physiological indicators and biological systems may be most impacted by MBIs...

Racial/ethnic minorities are more vulnerable to mental and physical health problems, but we know little about the psychobiological underpinnings of these disparities. In this study, we examined racial/ethnic differences in cortisol diurnal patterns and affect as initial steps toward elucidating long-term health disparities. A racially/ethnically diverse (39.5% White, 60.5% minority) sample of 370 adolescents (57.3% female) between the ages of 11.9 and 18 years (M = 14.65 years, SD = 1.39) participated in this study...

PURPOSE: To explore the effects of the first all-female transantarctic expedition on hormonal axes pertinent to reproductive and metabolic function. METHODS: Six females (aged 28-36, BMI 24.2 ±0.97 kgm) hauled 80kg sledges 1700km in 61 days. Estimated average energy intake was 20.8 ± 0.103 MJ/day (4970 ±25 kcal/day). Whole and regional body composition was measured by DXA one and two months before and 15 days after, the expedition. Body fat was also estimated by skinfold and bioimpedance immediately before and after the expedition...

Effective regulation of the hypothalamic-pituitary-adrenal axis (HPA-axis) has been linked to numerous health outcomes. Within-person variation in diurnal measures of HPA-axis regulation assessed over days, months, and years can range between 50-73% of total variation. In this study of 59 youth (ages 8-13), we quantified the stability of the cortisol awakening response (CAR), the diurnal slope, and tonic cortisol concentrations at waking and bedtime across 8 days (2 sets of 4 consecutive days separated by 3 weeks), 3 weeks, and 3 years...

The objective was to investigate the relationship between various aspects of informal caregiving and diurnal patterns of salivary cortisol, with special attention to the moderating effect of sex and work status. The study population was composed of 3727 men and women from the British Whitehall II study. Salivary cortisol was measured six times during a weekday. Aspects of caregiving included the relationship of caregiver to recipient, weekly hours of caregiving, and length of caregiving. Diurnal cortisol profiles were assessed using the cortisol awakening response (CAR) and diurnal cortisol slopes...

RATIONALE: Hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis has been widely reported in depression, and evidence suggests that selective serotonin reuptake inhibitors (SSRIs) might exert their therapeutic effects through altering cortisol secretion. OBJECTIVE: This study assessed the effects of SSRI administration on diurnal cortisol secretion in healthy volunteers. METHODS: Sixty-four healthy men and women were randomised to receive either 10 mg escitalopram or placebo for six days in a double-blind fashion...

BACKGROUND: The relationship between physiological stress measures and body composition or behavioral problems in older children remains controversial, and data in young children are lacking. The aim of the study was to investigate this relationship in predominantly healthy preschool children. METHOD: Physiological stress measures were assessed using diurnal salivary alpha-amylase (sAA) and salivary cortisol, nail cortisol and parasympathetic activation (PNS) by overnight heart rate variability, and body composition (body mass index, skinfold thickness) and behavior problems (using the Strengths and Difficulties Questionnaire) in 324 children aged 2-6 years of the SPLASHY study...

Culturally linked family influences during adolescence are important predictors of health and well-being for Latino youth, yet few studies have examined whether these familial influences are associated with indicators of typical physiological stress processes. Following a cultural neurobiology framework, we examined the role of family in the everyday lives of Latino adolescents (N = 209; Mage = 18.10; 85.1% Mexican descent; 64.4% female) by investigating familism values and perceptions of parent support as well as daily family assistance behaviors in relation to hypothalamic-pituitary-adrenal axis diurnal patterns, indexed by salivary cortisol five times a day for 3 weekdays...

Acute stress response measures serve as an indicator of physiological functioning, but have previously led to contradictory results in young children due to age-related cortisol hypo-responsivity and methodological inconsistencies in assessment. The aim of this study was to investigate stress responses during a validated age-adapted socio-evaluative stress task in children aged 2-6 years in a child care environment and to detect socio-demographic, task- and child-related characteristics of stress responses...

Psychological symptoms that arise in early childhood can follow a multitude of patterns into adolescence, including homotypic continuity (i.e., similar symptoms over time) and heterotypic continuity (i.e., a shift in symptoms over time). However, we know very little about the factors that distinguish homotypic vs. heterotypic continuity of early internalizing and externalizing symptoms over development. In a separate line of research, diurnal cortisol has been shown to predict later internalizing and externalizing problems...

Exogenously-administered oxytocin interacts with the hypothalamic-pituitary-adrenal axis to modulate endogenous cortisol levels, suggesting a synergistic role for these two hormones in the response to stress, cognitive performance, and the development of psycho-behavioural disorders. The cortisol awakening response (CAR) is considered a reliable measure of HPA axis function in humans. However, the CAR appears to vary considerably from day to day, and may be strongly influenced by the anticipated demands of the day ahead...

INTRODUCTION: Stress-related transient inhibition of memory formation in the hippocampus has been hypothesized as one of the underlying pathomechanisms of transient global amnesia (TGA). TGA episodes, during which patients cannot encode and recall new information (anterograde amnesia affecting episodic long-term memory), are frequently preceded by a psychologically or physically stressful event. METHODS: We measured salivary cortisol during acute TGA in 14 patients, as well as cortisol day-profiles and the effect of experimental exposure to stress (using the socially evaluated cold pressor test) on cortisol levels during the subacute phase...

Objectives: Exposure to life stresses can lead to diminution in the capacity of stress response systems to mount a robust response to new challenges, with blunting of dynamic range - the spread between maximal attainable and minimal resting levels. We investigate the association between early life adversity and the dynamic range of adult diurnal cortisol secretion. Method: In 35-86 year-old adults, cortisol assayed from 16 saliva samples over four consecutive days was used to compute diurnal dynamic range and area under the curve (AUC)...

BACKGROUND AND OBJECTIVE: Previous studies suggest that excessive cortisol levels after stroke are associated with cognitive dysfunction. However, limited data exist regarding associations between post-stroke cortisol levels, brain abnormalities, genetic factors, and cognitive outcome. We sought to study these issues in a longitudinal stroke survivors cohort. METHODS: Data from 182 cognitively intact ischemic stroke patients from the TABASCO study were available...

BACKGROUND: Survivors of sexual assault are vulnerable to long-term negative psychological and physical health outcomes, but few studies have investigated changes in cognition, emotional processing and brain function in the early stages after sexual assault. We used a multimodal approach to identify the cognitive and emotional correlates associated with sexual assault in women. METHODS: Twenty-seven female survivors of sexual assault were included within 4 weeks of the traumatic event, and they were compared with 20 age-matched controls...
