Project description:This study investigated associations between parenting stress in parents and self-reported stress in children with children's diurnal cortisol secretion and whether these associations are moderated by known stress-regulating capacities, namely child cognitive control. Salivary cortisol concentrations were assessed from awakening to evening on two weekend days from 53 6-to-7-year-old children. Children completed a cognitive control task and a self-report stress questionnaire with an experimenter, while parents completed a parenting stress inventory. Hierarchical, linear mixed effects models revealed that higher parenting stress was associated with overall reduced cortisol secretion in children, and this effect was moderated by cognitive control. Specifically, parenting stress was associated with reduced diurnal cortisol levels in children with lower cognitive control ability and not in children with higher cognitive control ability. There were no effects of self-reported stress in children on their cortisol secretion, presumably because 6-to-7-year-old children cannot yet self-report on stress experiences. Our results suggest that higher cognitive control skills may buffer the effects of parenting stress in parents on their children's stress regulation in middle childhood. This could indicate that training cognitive control skills in early life could be a target to prevent stress-related disorders.

Project description:Purpose of the Study:Middle-aged adults are often called upon to support aging parents. However, providing support to an aging parent with health problems and disability may be a stressful experience. This study asked whether giving everyday support to parents in the context of health problems and disability has implications for middle-aged children's diurnal cortisol and daily mood. Design and Methods:During four consecutive days, 148 middle-aged adults (mean age = 55) reported the support they gave to their parents and provided saliva 4 times a day (wake, 30 min post-wake, lunchtime, and bedtime). Multilevel models estimated within-person differences in positive affect (PA) and negative affect (NA), cortisol awakening response and area under the curve with respect to ground (AUC-G) as a function of giving same-day and previous-day support. We examined whether these associations are exacerbated when a parent has health problems or activities of daily living (ADL) needs. Results:Middle-aged children had significantly higher next-day AUC-G on days after they gave support to parents with ADL needs. When participants gave support to parents with ADL needs, they had significantly greater same-day PA and lower next-day NA. Giving support to parents with health problems was associated with significantly higher next-day NA. Implications:Giving support to parents is an ambiguous experience with implications for biological stress and daily mood. A biopsychosocial approach reveals under what conditions giving support to parents may become detrimental to health and well-being; this knowledge is essential for the development and implementation of interventions.

Project description:Midlife adults report greater investment in their children than in their parents, and these ties have important implications for well-being. To date, little research has addressed daily experiences in these ties. The present study examines daily experiences (negative and positive) with aging parents and adult children and their associations with daily negative affect and diurnal cortisol rhythms. Participants were middle-aged adults (N = 156; 56% women) from Wave 2 of the Family Exchanges Study, conducted in 2013, who completed a 7-day daily diary study, which included assessments of daily negative and positive social encounters and negative affect, and 4 days of saliva collection, which was collected 3 times a day (upon waking, 30 min after waking, and at bedtime) and assayed for cortisol. Multilevel models revealed that individuals were more likely to have contact with adult children than with parents but more likely to have negative experiences (negative interactions, avoidance, negative thoughts) with parents than with adult children. Nevertheless, contact and negative experiences with adult children were more consistently associated with negative affect and daily cortisol patterns than were interactions with parents. Findings are consistent with the intergenerational stake hypothesis, which suggests that individuals have a greater stake in their children than in their parents. Indeed, negative experiences with adult children may be more salient because tensions with adult children occur less frequently than do tensions with parents. (PsycINFO Database Record

Project description:Dysregulation of the hypothalamus-pituitary-adrenal (HPA) axis has been suggested as a potential mechanism linking sleep and cardiometabolic disorders. However, the associations of two primary outputs of the HPA axis, cortisol and its antagonist dehydroepiandrosterone (DHEA), with sleep are less well studied. In the Nurses' Health Study II, 233 postmenopausal women provided five timed saliva samples over one day (immediately upon waking, 45min, 4h, and 10h after waking, and prior to going to sleep) to measure cortisol and DHEA. Of these, 209 completed assessment of their habitual sleep patterns using the Pittsburgh Sleep Quality Index (PSQI). We used piecewise linear mixed models to compare cross-sectional associations of slopes reflecting diurnal cortisol and DHEA rhythms with overall sleep quality and with seven sub-components. Overall, we observed no differences in the diurnal patterns of cortisol or DHEA between good versus poor sleepers as assessed by the global PSQI score. However, longer sleep latency was associated with significantly reduced cortisol awakening rise (p=0.02). Poorer subjective sleep quality (p=0.02), shorter sleep duration (p=0.02), and lower sleep efficiency (p=0.03) were associated with slower rate of cortisol decline later in the day. Women reporting daytime dysfunction had a sharper cortisol decline early in the day (p=0.03) but a flattened decline later in the day (p=0.01). The differences in diurnal patterns of DHEA between good versus poor sleepers, though less pronounced, were similar in direction to those of cortisol. Self-reported sleep duration, efficiency, latency and daytime dysfunction were associated with altered diurnal rhythms of cortisol and, to a lesser extent, DHEA. These findings provide support for the interplay between sleep and the HPA axis that may contribute to cardiometabolic disease.

Project description:Inter-individual variability in metrics of hypothalamic-pituitary-adrenocortical (HPA) activity, such as the slope of the diurnal decline in cortisol, cortisol awakening response (CAR), and total cortisol output, have been found to associate inversely with trait ratings of extraversion and positive affect (E/PA) and positively with neuroticism and negative affect (N/NA) in some, but not all, investigations. These inconsistencies may partly reflect varied intensity of cortisol sampling among studies and reliance on self-rated traits, which are subject to reporting biases and limitations of introspection. Here, we further examined dispositional correlates of HPA activity in 490 healthy, employed midlife volunteers (M age=43 years; 54% Female; 86% white). Trait ratings were requested from participants and 2 participant-elected informants using the Positive and Negative Affect Schedule (PANAS) and Extraversion and Neuroticism dimensions of NEO personality inventories. CAR was assessed as percent increase in cortisol levels from awakening to 30min after awakening; and the diurnal slope and total output of cortisol [Area Under the Curve (AUC)] were determined from cortisol measurements taken at awakening, +4 and +9h later, and bedtime, across 3 workdays. Structural equation modeling was used to estimate multi-informant E/PA and N/NA factors. We used 3days of measurement as indicators to model each of the three latent cortisol factors (slope, CAR, and AUC). With the two latent emotionality and three latent cortisol indices included there was good fit to the data (?(2)(200)=278.38, p=0.0002; RMSEA=0.028, 90% CI=0.02-0.04; CFI/TLI=0.97/0.96; SRMR=0.04). After controlling for covariates (age, sex, race), results showed higher latent E/PA associated with a steeper diurnal slope (Standardized ?=-0.19, p=0.02) and smaller CAR (Standardized ?=-0.26, p=0.004), whereas N/NA did not associate with any cortisol metric (Standardized ?'s=-0.12 to 0.13, p's=0.10 to 0.53). These findings suggest that positive emotionality may be more closely associated with indices of diurnal cortisol release than negative emotionality.

Project description:This study examined whether resilience capacity moderates the association of daily perceived stress and affect with cortisol diurnal slope among relocated emerging adults. Relocated undergraduates (N = 98; aged 18-25 years) were recruited from three groups: Resilient, Vulnerable, and Control. The Resilient group required Risky Family Questionnaire (RFQ) scores ≥ 29 and Brief Resilience Scale (BRS) scores ≥ 3.6. The Vulnerable group required RFQ scores ≥ 29 and BRS scores ≤ 3. The comparison Control group required RFQ scores ≤ 21 and T-scores < 60 on PROMIS anxiety and depression symptoms. Mixed-effects models were used to test the unique associations of perceived stress, negative affect, and positive affect x group interactions (predictors) on diurnal cortisol slope (outcome) across 14 consecutive days. The Resilient group did not moderate the associations between daily stress or affect on cortisol diurnal slope. Instead, both the Resilient and Vulnerable groups with early family risk, showed a steeper diurnal slope unique to higher stress and a flatter slope unique to higher negative affect. Results suggest that riskier early family life was significantly associated with altered cortisol diurnal slope outcomes to stress (i.e., demand) and negative affect (i.e., distress). These associations were not attenuated by current resilience capacity.

Project description:Growing evidence from field studies has linked daily stressors to dysregulated patterns of diurnal cortisol. Less is known about whether naturally-occurring positive events in everyday life are associated with diurnal cortisol. The objectives of this study were to evaluate daily positive events as predictors of between-person differences and within-person (day-to-day) variations in diurnal cortisol parameters, in addition to daily positive events as buffers against the associations between daily stressors and cortisol. In the National Study of Daily Experiences, 1657 adults ages 33-84 (57% female) reported daily experiences during telephone interviews on 8 consecutive evenings. Saliva samples were collected 4 times per day on 4 interview days and assayed for cortisol. Multilevel models were used to estimate associations of daily positive events with cortisol awakening response (CAR), diurnal cortisol slope, and area under the curve (AUC). At the between-person level, people who experienced more frequent positive events exhibited a steeper diurnal cortisol slope, controlling for daily stressors, daily affect, and other covariates. At the within-person level, positive events in the morning (but not prior-night or afternoon/evening events) predicted steeper decline in cortisol across that day; positive events were also marginally associated with lower same-day AUC. Associations were not mediated by daily positive affect, and positive events did not buffer against stressor-related cortisol alterations. These findings indicate that individual differences and day-to-day variations in daily positive events are associated with diurnal cortisol patterns, independent of stressors and affect.

Project description:OBJECTIVES:To determine whether cortisol levels, both diurnal and pre-sleep, would vary as a function of MSLT and would be reduced by nightly placebo versus zolpidem 10 mg. METHODS:DSM-IVR diagnosed subjects with insomnia (N = 95), aged 32-70 yrs, having no other sleep disorder, unstable medical or psychiatric diseases or drug dependency served. On a screening MSLT 27 had MSLTs <10 min (Lo) and 42 > 15 min (Hi). Participants took 10 mg zolpidem or placebo, double-blind, nightly for 12 months. In months one and 12 urine was collected over 24 h in 8 hr-aliquots and assayed for cortisol (Ward Laboratories, Ann Arbor, MI). Saliva samples were collected 35 min before bedtime and the 30 min drug administration in month one and eight, and analyzed for cortisol levels (Salimetrics, State College, PA). RESULTS:Pre-sleep salivary cortisol was higher in insomniacs than controls, but did not differ as a function of MSLT. Nightly zolpidem reduced pre-sleep cortisol relative to placebo on month one and eight, with no month effects or interaction. Diurnal (0700-1500 h) urinary cortisol was higher overall in the Hi vs Lo MSLT subjects with insomnia, was stable across months, and was not reduced with zolpidem. CONCLUSIONS:Hyperarousal among subjects with insomnia as operationalized by MSLT is associated with higher diurnal urinary cortisol than those without hyperarousal, but not differential pre-sleep salivary cortisol. Zolpidem relative to placebo reduced pre-sleep salivary cortisol in all subjects, but not diurnal urinary cortisol.

Project description:The development and exacerbation of many psychiatric and neurologic conditions are associated with dysregulation of the hypothalamic pituitary adrenal (HPA) axis as measured by aberrant levels of cortisol secretion. Here we report on the relationship between the amplitude of diurnal cortisol secretion, measured across 3 typical days in 18 healthy individuals, and blood oxygen level dependant (BOLD) response in limbic fear/stress circuits, elicited by in-scanner presentation of emotionally negative stimuli, specifically, images of the World Trade Center (WTC) attack. Results indicate that subjects who secrete a greater amplitude of cortisol diurnally demonstrate less brain activation in limbic regions, including the amygdala and hippocampus/parahippocampus, and hypothalamus during exposure to traumatic WTC-related images. Such initial findings can begin to link our understanding, in humans, of the relationship between the diurnal amplitude of a hormone integral to the stress response, and those neuroanatomical regions that are implicated as both modulating and being modulated by that response.

Project description:OBJECTIVE:The present study explored pathways from the personality traits of neuroticism and conscientiousness through health-related behaviors to diurnal patterns of the stress hormone cortisol using data from a large national study. METHOD:Using prospective data from the Midlife in the United States (MIDUS II) study and the National Study of Daily Experiences (NSDE II, a MIDUS substudy), hierarchical linear modeling (HLM) and Monte Carlo estimation for multilevel model mediation were used to test direct and indirect effects (via general activity level, moderate and vigorous physical activity, lifetime history of regular smoking, and alcohol consumption) of neuroticism and conscientiousness on cortisol at wakeup, diurnal cortisol slope, and cortisol awakening response (N = 960). RESULTS:Initial HLM models showed greater levels of conscientiousness were associated with steeper (i.e., healthier) diurnal cortisol slope. Consistent with a hypothesized indirect biobehavioral pathway, when controlling for demographic factors, cortisol-related medications, daily stressors, and positive affect, HLM models showed the relationship between conscientiousness and diurnal cortisol slope was mediated by general activity levels. Lifetime history of smoking was associated with flatter diurnal cortisol slope, but did not mediate the effect of conscientiousness on diurnal cortisol slope. No effects were found for neuroticism. CONCLUSIONS:The results support a psychophysiological model of resilience--one that provides a more complete rendering of the health-protective mechanisms of conscientiousness via hypothalamic-pituitary-adrenal axis functioning. Specifically, the mediated pathway suggests greater engagement in the activities of day-to-day life are an instrumental means by which conscientious individuals experience healthier patterns of stress hormone secretion.
