AbstractHome baseline and laboratory stressor (Trier Social Stress Test for Children) measures of salivary cortisol were obtained from 82 participants (40 girls) aged 9, 11, 13, and 15 years. Measures of pubertal development, self-reported stress, parent reports of child depressive symptoms and fearful temperament, and cardiac measures of sympathetic and parasympathetic activity were also obtained. Significant increases in the home cortisol baselines were found with age and pubertal development. Cortisol stress reactivity differed by age group with 11-year-olds and 13-year-old boys showing blunted reactivity and 9-year-olds, 13-year-old girls, and 15-year-olds showing significant cortisol reactions. Cortisol reactivity correlated marginally with sexual maturation. Measures of sympathetic activity revealed increased sympathetic modulation with age. Higher sympathetic tone was associated with more fearful temperament, whereas greater cortisol reactivity was associated with more anxious and depressed symptoms for girls. The importance of these findings for the hypothesis that puberty-associated increases in hypothalamic–pituitary–adrenal axis activity heightens the risk of psychopathology is discussed.

Two of the most robust findings in depression research are (a) that women are twice as likely to become depressed than men and (b) that stress is an important risk factor for depression. Although sex differences in stress reactivity may be an important determinant of differential risk for depression, few studies have examined sex differences in neurobiological reactivity to stress. The purpose of the current study was to assess sex differences in the HPA axis response to stress in depressed versus healthy controls by comparing the cortisol response to the Trier Social Stress Test in a community sample of adolescents (ages 12–18). Depressed boys showed significantly heightened cortisol reactivity compared with depressed girls, whose response was blunted compared with nondepressed girls. This diverging pattern of cortisol reactivity to stress among depressed girls and boys may help to explain the sex difference in depression prevalence that emerges during the adolescent period.

Bidirectional Associations

AbstractMegan Gunnar's pubertal stress recalibration hypothesis was supported in a recent study of previously institutionalized (PI) youth such that increases in pubertal stage were associated with increases in cortisol stress reactivity. This work provides evidence that puberty may open up a window of recalibration for PI youth, resulting in a shift from a blunted to a more typical cortisol stress response. Using the same sample (N = 132), the current study aimed to elucidate whether increases in cortisol are associated with increases in adaptive functioning or whether they further underlie potential links to developmental psychopathology. Specifically, we examined the bidirectional associations between cortisol stress reactivity and both internalizing and externalizing symptoms across three timepoints during the pubertal period. Youth reported on their own internalizing symptoms and parents reported on youths’ externalizing symptoms. Cortisol reactivity was assessed during the Trier social stress test. Analyses revealed no associations between cortisol reactivity and externalizing symptoms across puberty for PI youth. However, longitudinal bidirectional associations did emerge for internalizing symptoms such that increases in cortisol reactivity predicted increases in internalizing symptoms and increases in internalizing symptoms predicted increases in cortisol reactivity. Findings suggest that recalibrating to more normative levels of cortisol reactivity may not always be associated with adaptive outcomes for PI youth.

Cortisol Reactivity

Physical activity is associated with a favourable (blunted) cortisol stress reactivity in healthy people. However, evidence from experimental study and with psychiatric patients is missing. This study examines whether exercise training impacts on cortisol stress reactivity in inpatients with major depressive disorder (MDD). These new insights are important because the stress reactivity of healthy people and patients with severe symptoms of depression might differ. Methods: The study was designed as a randomized controlled trial (trial registration number: NCT02679053). In total, 25 patients (13 women, 12 men, mean age: 38.1 ± 12.0 years) completed a laboratory stressor task before and after a six-week intervention period. Nine samples of salivary free cortisol were taken before and after the Trier social stress test (TSST). Fourteen participants took part in six weeks of aerobic exercise training, while 11 patients were allocated to the control condition. While the primary outcome of the study was depressive symptom severity, the focus of this paper is on one of the secondary outcomes (cortisol reactivity during the TSST). The impact of aerobic exercise training was examined with a repeated-measures analysis of variance. We also examined the association between change in depression and cortisol response via correlational analysis. Cortisol reactivity did not change from baseline to post-intervention, either in the intervention or the control group. Participation in six weeks of aerobic exercise training was not associated with participants’ cortisol reactivity. Moreover, depressive symptom change was not associated with change in cortisol response. Aerobic exercise training was not associated with patients’ stress reactivity in this study. Because many patients initially showed a relatively flat/blunted cortisol response curve, efforts might be needed to find out which treatments are most efficient to promote a normalization of HPA axis reactivity.

AbstractAccelerated pubertal development has been linked to adverse early environments and may heighten subsequent mental and physical health risks. Hypothalamic–pituitary–adrenal axis functioning has been posited as a mechanism whereby stress may affect pubertal development, but the literature lacks prospective tests of this mechanism. The current study assessed 277 youth (M = 10.84 years, SD = 1.14), 138 boys and 139 girls, who reported on their pubertal development and underwent the Trier Social Stress Test for Children at baseline and returned to the laboratory approximately 1 year later (M = 1.12 years, range = 0.59–1.98 years). For girls, lower cortisol area under the curve (with respect to ground) at Time 1 predicted more advanced pubertal development at Time 2, controlling for Time 1 pubertal development. This association persisted after additional covariates including age, body mass index, race, and maltreatment history were introduced, and was driven by adrenal rather than gonadal development. Cortisol was not linked to boys' subsequent pubertal development, and no interaction by gender or by maltreatment appeared. These results suggest that attenuated cortisol, reported in other studies of children exposed to early adversity, may contribute to accelerated pubertal tempo in girls.

Objective: Mindfulness interventions, which train practitioners to monitor their present-moment experience with a lens of acceptance, are known to buffer stress reactivity. Little is known about the active mechanisms driving these effects. We theorize that acceptance is a critical emotion regulation mechanism underlying mindfulness stress reduction effects. Method: In this three-arm parallel trial, mindfulness components were dismantled into three structurally equivalent 15-lesson smartphone-based interventions: (1) training in both monitoring and acceptance (Monitor+Accept), (2) training in monitoring only (Monitor Only), or (3) active control training (Coping control). 153 stressed adults (mean age = 32 years; 67% female; 53% white, 21.5% black, 21.5% Asian, 4% other race) were randomly assigned to complete one of three interventions. After the intervention, cortisol, blood pressure, and subjective stress reactivity were assessed using a modified Trier Social Stress Test. Results: As predicted, Monitor+Accept training reduced cortisol and systolic blood pressure reactivity compared to Monitor Only and control trainings. Participants in all three conditions reported moderate levels of subjective stress.Conclusions: This study provides the first experimental evidence that brief smartphone mindfulness training can impact stress biology, and that acceptance training drives these effects. We discuss implications for basic and applied research in contemplative science, emotion regulation, stress and coping, health, and clinical interventions.
