Feeling bad is not always unhealthy: Culture moderates the link between negative affect and diurnal cortisol profiles.

ABSTRACT: Prior research has demonstrated that the daily experience of negative affect is associated with increased levels of proinflammatory activity as evidenced by higher interleukin-6 among Americans but not among Japanese. This cultural difference may be driven by culturally divergent beliefs about negative affect as a source of threat to self-image versus as natural and integral to life. Here, we examined whether culture may moderate the relationship between negative affect and biological stress responses, with a focus on the hypothalamic-pituitary-adrenal (HPA) axis activity. By using culturally matched surveys of Americans (N = 761) and Japanese (N = 328), we found that negative affect was associated with a flattening of the diurnal cortisol slope among Americans after controlling for demographic variables, personality traits, sleep patterns, and health behaviors. In contrast, the association between negative affect and the HPA axis activity was negligible among Japanese. Moreover, we assessed biological health risk with biomarkers of both inflammation (interleukin-6 and C-reactive protein levels) and cardiovascular function (higher systolic blood pressure and total-to-HDL cholesterol ratio) and found that the relationship between negative affect and increased biological health risk, which was observed only among Americans, was mediated by the flattening of the diurnal cortisol rhythm. These findings suggest that cultural differences in how emotions are construed may make the experience of negative affect more or less stressful and differentially consequential for health.

Cognitive control moderates parenting stress effects on children's diurnal cortisol.

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.

Age moderates the association between social integration and diurnal cortisol measures.

Project description:Social integration is defined as the degree to which an individual participates in a broad range of social relationships. Although measures of social integration vary across studies, it is often assessed as the number of social roles (e.g., parent, friend, student, volunteer) that an individual reports actively participating in. More socially integrated individuals tend to be healthier than those less socially integrated, but the biological mechanisms through which this occurs remain unclear. One possibility is that social integration might alter the function of the hypothalamic-pituitary-adrenal axis, of which cortisol is a key product, and in turn influence a broad range of health outcomes. This study examined the association between social integration and two indices of cortisol in a community sample of 680 healthy men and women aged 18-55. Because the social roles held by younger individuals may be more numerous yet superficial than those held by older individuals, this study also tested the hypothesis that these associations could be moderated by age such that lower levels of integration would be associated with cortisol dysregulation for older but not younger individuals in our sample. Participants provided salivary cortisol samples during waking hours on three days that were used to calculate diurnal cortisol levels and slopes. Increased social integration was associated with lower cortisol AUC among older (ages 35-55) but not younger (ages 18-34) individuals in our sample. Moreover, while increased social integration was associated with steeper diurnal cortisol slopes regardless of age, this association was strongest among older individuals. Differences in health behaviors, affect, and psychological stress did not mediate these associations. The results of this study support cortisol as a candidate biological mechanism through which increased social integration is associated with better physical health among older individuals.

Racial/ethnic disparities in cortisol diurnal patterns and affect in adolescence.

Project description: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. These adolescents provided 16 cortisol samples (4 samples per day across 4 days), allowing the computation of diurnal cortisol slopes, the cortisol awakening response, and diurnal cortisol output (area under the curve), as well as daily diary ratings of high-arousal and low-arousal positive and negative affect. Consistent with prior research, we found that racial/ethnic minorities (particularly African American and Latino youth) exhibited flatter diurnal cortisol slopes compared to White youth, F (1, 344.7) = 5.26, p = .02, effect size g = 0.25. Furthermore, African American and Asian American youth reported lower levels of positive affect (both high arousal and low arousal) compared to White youth. Racial/ethnic differences in affect did not explain differences in cortisol patterns, suggesting a need to refine our models of relations between affect and hypothalamic-pituitary-adrenocortical activity. We conclude by proposing that a deeper understanding of cultural development may help elucidate the complex associations between affect and hypothalamic-pituitary-adrenocortical functioning and how they explain racial/ethnic differences in both affect and stress biology.

Rejection, feeling bad, and being hurt: using multilevel modeling to clarify the link between peer group aggression and adjustment.

Project description:The association between affiliating with aggressive peers and behavioral, social and psychological adjustment was examined. Students initially in 3rd, 4th, and 5th grade (N = 427) were followed biannually through 7th grade. Students' peer-nominated groups were identified. Multilevel modeling was used to examine the independent contributions of adolescents' typical peer context (between-person effect) and changes in peer context (within-person effects) to adolescents' adjustment. Typically affiliating with aggressive groups and affiliating with more aggressive groups than usual predicted higher aggression for all youth. Typically affiliating with aggressive groups predicted negative adjustment (lower social preference and self-worth, higher victimization) for girls but neutral or positive adjustment for boys. Although typical peer context was consistently associated with adjustment, changes in peer context predicted small changes in adjustment for several outcomes. Results underscored the need to adopt a more differentiated picture of adolescents' dynamic peer context and its association with normative development.

Daily interactions with aging parents and adult children: Associations with negative affect and diurnal cortisol.

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

Positive and negative affect and arousal: cross-sectional and longitudinal associations with adolescent cortisol diurnal rhythms.

Project description:ObjectivesPsychobiological research with adolescent populations tends to focus on negative mood, stress, and psychopathology, but the role of positive emotions is insufficiently understood. The current study examines the relative contributions of both negative and positive affective experiences to the basal activity of the hypothalamic-pituitary-adrenal axis, measured by levels of cortisol across the waking day.MethodsA sample of 315 ethnically and racially diverse high school students (mean age = 17.1 years, 73% female) completed a multiple-day naturalistic salivary cortisol protocol twice over a 5-year period. Along with each saliva sample, youth provided diary reports of their current mood states. Principal components analysis revealed four factors: high arousal positive affect (PA), low arousal PA, high arousal negative affect (NA), and low arousal NA.ResultsMultilevel growth curve models suggested that greater high arousal PA was associated with adaptive patterns of hypothalamic-pituitary-adrenal activity: steeper cortisol slope from waking to bedtime and lower evening cortisol, independent of NA. In addition, increases in high arousal PA over the 5-year follow-up period were associated with a steepening of the diurnal cortisol slope (β = -0.038, p = .009; negative values indicate the decrease of cortisol throughout the day) and lower evening cortisol levels (β = -0.661, p = .027) based on within-person fixed-effect regression analysis.ConclusionsThis study shows that high arousal PA, such as feeling alert and active, is associated with a steeper decline in cortisol throughout the day. Low arousal positive emotions did not display this relationship.

Feeling excited or taking a bath: Do distinct pathways underlie the positive affect-health link in the U.S. and Japan?

Project description:Feeling good is linked to better health in Western contexts. Recent studies show, however, that the affect-health link is not consistent across cultures. We suggest two reasons for such inconsistency. The first follows from research showing that North American (vs. East Asian) cultures tend to value high arousal positive (HAP) states, for example, excited, more than low arousal positive (LAP) states, for example, calm. The second is one we propose for the first time. Positive affective experience is manifest in internal feelings but also in affective practices, such as taking a bath (a highly valued affective experience in Japan) or a fitness workout (a highly valued affective experience in the United States). We hypothesized that the HAP feelings/practices-health link would be stronger in the United States versus Japan, and the LAP feelings/practices-health link would be stronger in Japan versus the United States. Using survey samples from the United States (N = 640) and Japan (N = 382), we examined how health outcomes are shaped by positive affective feelings and practices varying in arousal. In a first set of analyses, HAP feelings predicted better physical and biological health in the United States but not in Japan. No cultural differences were consistently found for the effect of LAP feelings on health. In addition, engaging in HAP practices predicted better physical and biological health in the United States whereas engaging in LAP practices predicted better physical health in Japan but not in the United States. These findings suggest that the pathways underlying the culture-health link are culturally variable. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

Preschoolers' everyday conflict at home and diurnal cortisol patterns.

Project description:Early life family conflict is associated with physical health problems later in life, but little is known about the biological pathways through which conflict at home exerts it deleterious effects on health. The goal of this study was to investigate the associations between naturalistically assessed conflict in everyday family environments and diurnal cortisol in preschool-aged children.Forty-four children aged 3-5 from two-parent families provided six saliva samples per day over 2 days from a Saturday morning through Sunday night. For a full day on either Saturday or Sunday, children wore a child version of the Electronically Activated Recorder, a digital voice recorder that records ambient sounds while participants go about their daily lives. Parents provided reports of child externalizing behaviors as well as daily reports of child conflicts.Diurnal salivary cortisol over the two weekend days of the study.Greater Electronically Activated Recorder-assessed child conflict at home was associated with children having lower cortisol at wakeup (p < .009) and flatter diurnal cortisol slopes (p < .007). These associations remained significant even after controlling for parent reports of child externalizing behaviors, parent reports of daily child conflicts, and child age and sex.These findings indicate that taking into consideration everyday conflicts at home may be key to our understanding of stress-health links in young children.

A Metabolomic Approach for Predicting Diurnal Changes in Cortisol.

Project description:Introduction: The dysregulation of cortisol secretion has been associated with a number of mental health and mood disorders. However, diagnostics for mental health and mood disorders are behavioral and lack biological contexts. Objectives: The goal of this work is to identify volatile metabolites capable of predicting changes in total urinary cortisol across the diurnal cycle for long-term stress monitoring in psychological disorders. Methods: We applied comprehensive two-dimensional gas chromatography coupled with time-of-flight mass spectrometry to sample the urinary volatile metabolome using an untargeted approach across three time points in a single day for 60 subjects. Results: The finalized multiple regression model includes 14 volatile metabolites and 7 interaction terms. A review of the selected metabolites suggests pyrrole, 6-methyl-5-hepten-2-one and 1-iodo-2-methylundecane may originate from endogenous metabolic mechanisms influenced by glucocorticoid signaling mechanisms. Conclusion: This analysis demonstrated the feasibility of using specific volatile metabolites for the prediction of secreted cortisol across time.

Foster parent responsiveness and young children's diurnal cortisol production.

Project description:Foster children are at risk for dysregulated hypothalamic pituitary adrenal (HPA) axis functioning, conferring risk for negative health outcomes. Responsive parenting may support young children's HPA axis regulation; however, few studies have examined the association between responsive parenting and cortisol production among children in foster care. In a sample of 97 foster parent-child dyads, we examined whether variation in foster parent responsiveness was linked to children's waking and bedtime levels of cortisol. Children's saliva samples were collected at wake-up and bedtime for three consecutive days. Foster parent responsiveness, as indicated by parent sensitivity, intrusiveness, and positive regard, was assessed during video-recorded semistructured play interactions between foster parents and children. Foster parent responsiveness significantly predicted children's waking cortisol levels (β = 0.26, p = .023). Follow-up analyses revealed that foster parent sensitivity uniquely predicted waking cortisol (β = 0.46, p = .006), over and above other dimensions of parenting, such that children with more sensitive foster parents had higher waking cortisol than children with less sensitive foster parents. The association between foster parent sensitivity and the waking-to-bedtime slope of cortisol across the day was nonsignificant. Findings suggest that sensitive caregiving may support foster children's healthy HPA axis functioning.
