Cardiovascular,hormonal, and emotional responses to the TSST in relation to sex and menstrual cycle phase

The prevalence of stress disorders differs between men and women. An understanding of how men and women vary in acute stress responses may help to understand these sex differences. We compared responses to the TSST and a control task in healthy men (N=28) and women tested in two phases (Follicular N=29, Luteal N=23) of the menstrual cycle. Men exhibited greater cortisol responses to stress than women in either phase. Luteal women exhibited the greatest subjective and allopregnanolone responses to stress, whereas follicular women exhibited blunted noradrenaline responses. Partial correlations controlling for group differences revealed that individuals who were most sensitive to the subjective effects of stress exhibited the largest salivary cortisol, noradrenaline, and allopregnanolone responses and the smallest progesterone responses to stress. We discuss our findings in the context of sex differences in the prevalence of stress‐linked disorders.     

Hypothalamic-pituitary-adrenal axis reactivity in chronic fatigue syndrome and health under psychological,physiological, and pharmacological stimulation

OBJECTIVES: Subtle alterations of the hypothalamic-pituitary-adrenal (HPA) axis in chronic fatigue syndrome (CFS) have been proposed as a shared pathway linking numerous etiological and perpetuating processes with symptoms and observed physiological abnormalities. Because the HPA axis is involved in the adaptive responses to stress and CFS patients experience a worsening of symptoms after physical and psychological stress, we tested HPA axis functioning with three centrally acting stress tests. METHODS: We used two procedures mimicking real-life stressors and compared them with a standardized pharmacological neuroendocrine challenge test. CFS patients were compared with healthy control subjects regarding their cardiovascular and endocrine reactivity in a psychosocial stress test and a standardized exercise test, and their endocrine response in the insulin tolerance test (ITT). RESULTS: Controlling for possible confounding variables, we found significantly lower ACTH response levels in the psychosocial stress test and the exercise test, and significantly lower ACTH responses in the ITT, with no differences in plasma total cortisol responses. Also, salivary-free cortisol responses did not differ between the groups in the psychosocial stress test and the exercise test but were significantly higher for the CFS patients in the ITT. In all tests CFS patients had significantly reduced baseline ACTH levels. CONCLUSIONS: These results suggest that CFS patients are capable of mounting a sufficient cortisol response under different types of stress but that on a central level subtle dysregulations of the HPA axis exist.     

Sex steroid levels temporarily increase in response to acute psychosocial stress in healthy men and women

It is well known that acute psychosocial stress activates the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system (SNS). However, the effect of acute psychosocial stress on the hypothalamic-pituitary-gonadal (HPG) axis and levels of sex steroids are less known. The aim of this study was to investigate the effect of acute psychosocial stress on serum concentrations of sex steroids in healthy men and women. Twenty men and 19 women (age 30-50 years) underwent Trier Social Stress Test (TSST), a tool for investigating psychobiological stress responses in a laboratory setting. Blood samples were collected before, directly after the stress test, and after 30 min of recovery. Concentrations of androgens were measured with high specificity LC-MS/MS method; concentrations of cortisol, estradiol and sex hormone-binding globulin were determined using immunoassays. In both men and women we observed significantly elevated levels of testosterone, estradiol, androstenedione and sex hormone binding globulin along with significantly increased adrenocorticotropic hormone (ACTH), serum cortisol, heart rate, systolic blood pressure (SBP), and diastolic blood pressure (DBP) as a response to the stressor. Thus, even though the HPG axis and the production of sex steroids may be inhibited during prolonged periods of stress, the sex steroid levels may increase in the initial phase of acute psychosocial stress.     

Adult attachment representations predict cortisol and oxytocin responses to stress

There are many factors contributing to individual variations in the response to stressful experiences. The present study evaluated the patterns of stress responses according to attachment representations in 28 adults from a community sample, plus 46 subjects expected to be particularly sensitive to stress, having been exposed during childhood and/or adolescence to traumatizing events such as abuse or potentially lethal illnesses. Subjects were given the Adult Attachment Interview, which provides attachment classifications, and the Trier Social Stress Test (TSST), involving an experimental psychosocial challenge. Subjective responses to the TSST, as well as saliva samples (assayed for cortisol) and blood plasma samples (assayed for ACTH and oxytocin) were collected before, during and after the stress procedure. The stress responses presented specific patterns according to attachment classifications. Subjects with an autonomous attachment classification reported relatively low subjective stress, they presented a moderate response of the hypothalamic-pituitary-adrenal (HPA) axis (ACTH and cortisol), and a high level of oxytocin. Subjects with a dismissing classification reported a moderate subjective stress, they presented an elevated response of the HPA axis, and moderate levels of oxytocin. Subjects with a preoccupied classification presented moderate levels of subjective stress, and of HPA response, and a relatively low level of oxytocin. Finally, subjects with an unresolved classification reported elevated subjective stress; they presented a suppressed HPA response, and moderate levels of oxytocin. These data support the notion that attachment representations may affect stress responses, and suggest a specific role of oxytocin in both the attachment system and the stress system.     

Sex differences in glucocorticoid sensitivity of proinflammatory cytokine production after psychosocial stress.

OBJECTIVE: Men and women show marked differences in susceptibility to disorders related to the immune system. These gender differences have been proposed to be mediated by functional interactions of the hypothalamus-pituitary-adrenal (HPA) and hypothalamus-pituitary-gonadal (HPG) axes. A potential mechanism involved in this interaction is the glucocorticoid (GC) sensitivity of relevant target tissues for GC. Therefore, the aim of the study reported here was to investigate the impact of psychosocial stress and HPA axis activation on the GC sensitivity of proinflammatory cytokine production in men and women. METHODS: A total of 45 healthy subjects were investigated. Eighteen women in the luteal phase of their menstrual cycle and 27 men were exposed to a psychosocial stress test (Trier Social Stress Test). Salivary free cortisol levels were measured repeatedly after exposure to the stressor. GC sensitivity was assessed in vitro by dexamethasone inhibition of lipopolysaccharide-stimulated production of interleukin-6 and tumor necrosis factor-alpha. RESULTS: The stress test induced significant increases in salivary free cortisol with no significant differences between men and women. In contrast, GC sensitivity and lipopolysaccharide-stimulated cytokine production showed large gender differences. In men GC sensitivity was markedly increased 1 hour after stress, whereas GC sensitivity decreased significantly in women. Similarly, lipopolysaccharide-induced cytokine production decreased in response to stress in men but increased in women. CONCLUSIONS: These results demonstrate that despite similar free cortisol responses of men and women (studied in the luteal phase) to psychosocial stress, gender may exert differential effects on the immune system by modulating GC sensitivity of proinflammatory cytokine production.     

Cortisol response to the Trier Social Stress Test in pregnant women at risk for postpartum depression

Antepartum depression and anxiety are risk factors for postpartum depression (PPD). Postpartum abnormalities in hypothalamic-pituitary-adrenal (HPA) reactivity are associated with PPD. It is not known if antepartum HPA abnormalities exist in women at risk for PPD (AR-PPD). We measured salivary cortisol response to the Trier Social Stress Test (TSST) in 44 (24 AR-PPD, 20 healthy comparison) pregnant women. Depression and anxiety were measured using the Edinburgh Postnatal Depression Scale (EPDS) and Spielberger State-Trait Anxiety Inventory-State (STAI-S). We analyzed longitudinal changes in cortisol using generalized estimating equation methods to control for the correlation within subjects at the six TSST time points. Group differences in area under the curve (AUC) were examined. A majority (70.8 %) of the AR-PPD had prior depression. EPDS total score was higher in AR-PPD vs. comparison women (mean EPDS?=?9.8?±?4.9 vs. mean EPDS?=?2.4?±?2.0 respectively, p?<?0.001). Mean STAI-S total score was higher in AR-PPD vs. comparison women at all TSST time points and over time (z?=?2.71, df?=?1, p?=?0.007). There was no significant difference in cortisol concentration over time between groups. We observed no detectable difference in cortisol response to psychosocial stress induced by the TSST despite clinically significant between-group differences in current/past depression and current symptomatology.     

Cortisol response to the Trier Social Stress Test in obese and reduced obese individuals

Impact of body weight loss, body fat distribution and the nutritional status on the cortisol response to the Trier Social Stress Test (TSST) was investigated in this study. Fifty-one men (17 non-obese, 20 abdominally obese and 14 reduced obese) and 28 women (12 non-obese, 10 peripherally obese and 6 reduced obese) were subjected to the TSST in fed and fasted states. The TSST response was determined using salivary cortisol measurements. The nutritional status (being fed or fasted) had no effect on the cortisol levels during and following the TSST. Reduced obese men exhibited lower cortisol levels than non-obese men. Cortisol levels in obese men were not different from those of non-obese and reduced obese subjects. In women, there was no significant difference between groups. These finding suggest that weight status in men influences cortisol reactivity to a psychological stress and the different responses seen among genders could be linked to the different fat distributions that characterize men and women.     

Hormonal and behavioral responses to stress in lactating and non-lactating female common marmosets (Callithrix jacchus)

In several mammalian species, hypothalamic-pituitary-adrenal (HPA) and behavioral responses to stressors are down-regulated in lactating females, possibly preventing stress-induced disruptions of maternal care. Experimental elevations of HPA axis hormones have been found to inhibit maternal behavior in lactating common marmoset monkeys (Callithrix jacchus), raising the question of whether lactating female marmosets also have blunted endogenous responses to stress. Therefore, we compared HPA and behavioral responses to standardized stressors in reproductively experienced female common marmosets that were undergoing ovulatory cycles and that either were (N = 7) or were not lactating (N = 8). Each marmoset underwent (1) a restraint stressor during the early follicular phase of the ovarian cycle (approximately 5 weeks postpartum for lactating females) and (2) exposure to a simulated hawk predator during the early to mid-luteal phase (approximately 7 weeks postpartum for lactating females). Lactating females were tested in the presence of one of their infants. Blood samples were collected before, during, and immediately after each test for determination of plasma adrenocorticotropic hormone (ACTH) and cortisol concentrations. Both stressors caused significant elevations in plasma ACTH and cortisol levels, and significant decreases in cortisol:ACTH ratios; however, lactating and non-lactating females showed no significant differences in their endocrine or behavioral responses to either stressor, or in baseline ACTH or cortisol levels. These findings suggest that in contrast to several other mammalian species, lactating female marmosets maintain full behavioral and HPA responsiveness to stress, at least in the presence of their infants.     

Male gamblers have significantly greater salivary cortisol before and after betting on a horse race, than do female gamblers

Prevalence rates of gambling are influenced by gender. Among normative populations, hypothalamic-pituitary-adrenal (HPA) axis response to stress is affected by gender. However, pathological, compared to recreational, gamblers demonstrate perturbations in HPA activation in response to gambling stimuli. We examined whether there were gender differences in HPA response to gambling in a naturalistic setting among horse-race bettors and scratch-off lottery bettors. Salivary cortisol was collected from horse-race gamblers (n = 32) and scratch-off lottery ticket players (n = 39) before and after (0, 10, or 20 min) betting on a horse race at an off-track betting establishment. Salivary cortisol levels were significantly higher among men than among women, both prior to and following, betting on a horse race. Among women, but not men, there was a decline in salivary cortisol across time in scratch-off bettors, whereas women horse-race bettors maintained consistent low concentrations of salivary cortisol at every time point sampled. Together these data suggest that engaging in gambling may have different effects on stress responses of men, compared to women. Whether these gender differences in HPA activation contribute to gender-related differences in gambling behavior is the subject of ongoing investigation.     

Parity does not alter baseline or stimulated activity of the hypothalamus-pituitary-adrenal axis in women

Pregnancy is associated with considerable physiological adaptations, some of which long outlast the state of pregnancy. Although it is well documented that pregnancy produces alterations of the hypothalamus-pituitary-adrenal axis, the longer-term effects of pregnancy on this system have not been systematically examined in humans. Subjects in the present study were 159 nulliparous and 265 parous women. Data analysis revealed no impact of parity on baseline activity (salivary cortisol: response to awakening, F 相似文献   

Adrenocorticotropin hormone, beta-endorphin and cortisol responses to oCRF in melancholic patients.

Several authors have reported attenuated adrenocorticotropin hormone (ACTH) responses to corticotropin releasing factor (CRF) administration in melancholic patients as compared with healthy controls. In order to explore the integrity of the hypothalamic-pituitary-adrenal (HPA)-axis in melancholics, we examined the following parameters in 98 subjects: the ACTH; beta-endorphin; and cortisol responses to ovine CRF (oCRF) (100 micrograms/i.v.); and the postdexamethasone cortisol values. We found significant lower CRF-induced ACTH responses in melancholic patients as opposed to healthy controls and minor depressives, while major depressives occupied an intermediate position. The psychopathological correlates of the blunted CRF-induced ACTH responses were feelings of worthlessness, self-reproach, or excessive guilt. The CRF-stimulated beta-endorphin and cortisol response did not differ between the study samples. Higher baseline plasma cortisol was associated with attenuated CRF-induced ACTH responses, but these effects were not pertinent to melancholia. There were no relationships between the disordered oCRF test results, and postdexamethasone cortisol values, age, body size, sex and severity of illness. The diagnostic power of the oCRF and the dexamethasone suppression test for melancholia is enhanced when both test results are combined.     

Personality dimensions harm avoidance and self-directedness predict the cortisol awakening response in military men

To account for individual differences in vulnerability for stress-related disorders, studies have examined the relationship between hypothalamic-pituitary-adrenal (HPA) axis functioning and personality. The present study examined the relationship between the free fraction of cortisol in saliva after awakening and personality as measured with Cloninger's Temperament and Character Inventory [Cloninger, C.R., Przybeck, T.R., Svrakic, D.M., Wetzel, R.D., 1994. The Temperament and Character Inventory (TCI): A Guide to its Development and Use. Washington University, Center for Psychobiology of Personality, St. Louis, MO] in 107 healthy male soldiers. Harm avoidance explained 9% of variance in cortisol levels after awakening (AUCG), and harm avoidance and self-directedness predicted 10% of variance in mean cortisol increase. The cortisol awakening response (CAR) was lower in participants with low scores on harm avoidance, and mean cortisol increase after awakening was higher in soldiers high on self-directedness and harm avoidance. These results show that the CAR is related to personality and that it can be used to examine individual differences in HPA (re)activity.     

Responses of calves to acute stress: individual consistency and relations between behavioral and physiological measures

The present study examined the consistency over time of individual differences in behavioral and physiological responsiveness of calves to intuitively alarming test situations as well as the relationships between behavioral and physiological measures. Twenty Holstein Friesian heifer calves were individually subjected to the same series of two behavioral and two hypothalamo-pituitary-adrenocortical (HPA) axis reactivity tests at 3, 13 and 26 weeks of age. Novel environment (open field, OF) and novel object (NO) tests involved measurement of behavioral, plasma cortisol and heart rate responses. Plasma ACTH and/or cortisol response profiles were determined after administration of exogenous CRH and ACTH, respectively, in the HPA axis reactivity tests. Principal component analysis (PCA) was used to condense correlated measures within ages into principal components reflecting independent dimensions underlying the calves' reactivity. Cortisol responses to the OF and NO tests were positively associated with the latency to contact and negatively related to the time spent in contact with the NO. Individual differences in scores of a principal component summarizing this pattern of inter-correlations, as well as differences in separate measures of adrenocortical and behavioral reactivity in the OF and NO tests proved highly consistent over time. The cardiac response to confinement in a start box prior to the OF test was positively associated with the cortisol responses to the OF and NO tests at 26 weeks of age. HPA axis reactivity to ACTH or CRH was unrelated to adrenocortical and behavioral responses to novelty. These findings strongly suggest that the responsiveness of calves was mediated by stable individual characteristics. Correlated adrenocortical and behavioral responses to novelty may reflect underlying fearfulness, defining the individual's susceptibility to the elicitation of fear. Other independent characteristics mediating reactivity may include activity or coping style (related to locomotion) and underlying sociality (associated with vocalization).     

Chronic ACTH autoantibodies are a significant pathological factor in the disruption of the hypothalamic-pituitary-adrenal axis in chronic fatigue syndrome, anorexia nervosa and major depression

Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis is a commonly recognized feature of many pathological conditions. Abnormal adrenal responses to experimental manipulation have been well documented in patients suffering from chronic fatigue syndrome, anorexia nervosa and major depression. Yet no defect of any single organ, gland or brain region has been identified as a cause of these abnormalities. The disruption of the HPA axis that occurs in these conditions can be understood if an interfering factor is present in these patients. Evidence indicates that this interfering factor is adrenocorticotropin hormone (ACTH) autoantibodies. Chronic high levels of ACTH autoantibodies will significantly disrupt the HPA axis and force the body to compensate for an impaired cortisol response. The resulting effect of chronic ACTH autoantibody interference is the manifestation of adrenocortical insufficient symptoms and psychological disturbances. Some symptoms of chronic fatigue syndrome, anorexia nervosa and major depression, such as anxiety, are the adverse effects of mechanisms compensating for less effective ACTH due to autoantibodies. Furthermore, these patients engage in extraordinary behaviors, such as self-injury, to increase their cortisol levels. When this compensation is inadequate, symptoms of adrenocortical insufficiency appear. Corticosteroid supplements have been demonstrated to be an effective treatment for chronic fatigue syndrome, anorexia nervosa and major depression. It allows the patients to have the corticosteroids they require for daily functioning and daily stressors. This therapy will relieve the patients of their symptoms of adrenocortical insufficiency and permit their cortisol-stimulating mechanisms to operate at levels that will not cause pathological problems.     

Sex differences in HPA axis activity in response to a meal

BackgroundSex may influence the relationship between HPA axis functioning and obesity. This has been suggested to be due to sex-specific differences in body composition, body fat distribution and psychological variables. Age and the use of oral contraceptives may also influence the relationship between HPA axis functioning and obesity.ObjectiveTo systematically investigate whether body composition, body fat distribution, psychological variables, age, or possible oral contraceptive use contribute to sex differences in HPA axis activity in response to a meal.MethodsSubjects were men (n = 19) and women (n = 19) between 18 and 51 years old with BMI between 20.3 and 33.2 kg/m². HPA axis activity was measured by salivary free cortisol levels before consuming a meal, and at 45, 75 and 125 min postprandial on four repeated test days. Anthropometric and body composition measurements were performed. Questionnaires were used to assess cognitive eating behavior and trait anxiety level.ResultsNo differences between the test days in postprandial cortisol responses appeared. Responses were significantly higher in men compared with women (p < .05). No significant correlations were found between cortisol concentrations and sex-specific body composition or body fat distribution. Psychological variables did not contribute to differences in cortisol responses after a meal between men and women. In women, baseline cortisol concentrations correlated inversely with age (p = .024).ConclusionHigher HPA axis activity following a meal in men vs. women remained irrespective of sex-specific differences in body composition, body fat distribution, psychological variables, or in age. In women baseline cortisol concentrations were age-dependent.     

Ontogeny of endocrine (ACTH, vasopressin, cortisol) responses to hypotension in lamb fetuses

We studied the ACTH, vasopressin (AVP), and cortisol responses to nitroprusside-induced hypotension in 27 chronically cannulated lamb fetuses between 0.53 and 0.98 gestation. Age-related differences in the hormonal responses to hypotension were found. Hypotension was associated with peak AVP levels of 7.8 +/- 2.7 pg/ml (mean +/- SE) in animals less than 0.68 gestation and 63.5 +/- 20 pg/ml in animals 0.89-0.98 gestation (P less than 0.05). The peak ACTH response was 95 +/- 20 pg/ml in the youngest animals and 380 +/- 111 pg/ml in animals 0.83-0.88 gestation (P less than 0.05). These observations suggest that maturation of the systems (possibly neuroendocrine) subserving the hormonal responses occurs in utero. Fetal plasma cortisol levels did not increase in response to the increase in ACTH except in animals 0.89-0.98 gestation. At this time, the basal plasma cortisol levels were high (58.8 +/- 16.8 pg/ml) and the ACTH response to hypotension was attenuated. Taken together, these findings suggest functional negative feedback regulation of ACTH by cortisol in the late gestation fetus.     

Anticipated next‐day demand affects the magnitude of the cortisol awakening response,but not subjective or objective sleep

Whilst the association between sleep and stress is well established, few studies have examined the effects of an anticipated stressor upon sleep and relevant physiological markers. The aim of the present study was to examine whether an anticipated stressor in the form of next‐day demand affects subjective and objective sleep, and multiple indices of the cortisol awakening response. Subjective and objective sleep and the cortisol awakening response were measured over three consecutive nights in 40 healthy adults in a sleep laboratory. During their second night, participants were informed that they would either be required to complete a series of demanding cognitive tasks, in a competition format, during the next day (anticipation condition; n = 22), or were given no instruction (sedentary condition; n = 18). Sleep was measured subjectively using sleep diaries, objectively using polysomnography, and saliva was measured at awakening, +15, +30, +45 and +60 min each morning, from which cortisol awakening response measurement indices were derived: awakening cortisol levels, the mean increase in cortisol levels and total cortisol secretion. There were no between‐group differences in subjective or objective sleep in the night preceding the anticipated demand; however, compared with the sedentary condition, those in the anticipation group displayed a larger mean increase in cortisol levels, representing the cortisol awakening response magnitude, on the morning of the anticipated demand. Overall, the results suggest that whilst anticipated stress affected the subsequent cortisol awakening response, subjective and objective sleep remained undisturbed. It is possible that the timing of an anticipated stressor, rather than its expected duration, may influence subsequent sleep disruption.     

Dysregulated diurnal cortisol pattern is associated with glucocorticoid resistance in women with major depressive disorder

Dysfunction of the hypothalamic–pituitary–adrenal (HPA) axis is believed to play a role in the pathophysiology of depression. To investigate mechanisms that may underlie this effect, we examined several indices of HPA axis function – specifically, diurnal cortisol slope, cortisol awakening response, and suppression of cortisol release following dexamethasone administration – in 26 pre-menopausal depressed women and 23 never depressed women who were matched for age and body mass index. Salivary cortisol samples were collected at waking, 30 min after waking, and at bedtime over three consecutive days. On the third day, immediately after the bedtime sample, participants ingested a 0.5 mg dexamethasone tablet; they then collected cortisol samples at waking and 30 min after waking the following morning. As predicted, depressed women exhibited flatter diurnal cortisol rhythms and more impaired suppression of cortisol following dexamethasone administration than non-depressed women over the three sampling days. In addition, flatter diurnal cortisol slopes were associated with reduced cortisol response to dexamethasone treatment, both for all women and for depressed women when considered separately. Finally, greater self-reported depression severity was associated with flatter diurnal cortisol slopes and with less dexamethasone-related cortisol suppression for depressed women. Depression in women thus appears to be characterized by altered HPA axis functioning, as indexed by flatter diurnal cortisol slopes and an associated impaired sensitivity of cortisol to dexamethasone. Given that altered HPA axis functioning has been implicated in several somatic conditions, the present findings may be relevant for understanding the pathophysiology of both depression and depression-related physical disease.     

Endocrine response of gilts to various common stressors: a comparison of indicators and methods of analysis

The first aim of the present study was to determine whether various common events encountered by pigs in commercial farms or experimental units induce activation of the sympathetic and hypothalamo-pituitary-adrenal (HPA) axes. The second aim was to compare the efficiency of various indicators and methods of analysis to detect the occurrence of a stress reaction. Responses to two blood sampling methods, immobilization by snaring, brief electric shocks, loud noise, ear tagging, tattooing, biopsy, pen relocation or delayed feeding time have been evaluated. Series of blood and saliva samplings (from 10 min before to 120 min after stressor application) were collected for each stressor on a total of 8 catheterized sows. Plasma glucose, lactate, cortisol and ACTH levels as well as salivary cortisol were measured. Acute increases of cortisol or ACTH (at least at time points +5 or +15 min) were observed for intense noise, electric shocks, ear tagging, tattooing, biopsy, cava blood sampling, snaring and pen relocation. Snaring, relocation and vena cava blood sampling generated longer stress responses whereas delayed meal and tail blood sampling had no influence. Plasma lactate was also significantly increased in several time-points after stressor application contrarily to plasma glucose. Comparison of successive time points with the starting basal level and comparison with the control group were more sensitive methods to detect a stress response to moderate stressors like electric shocks and tattooing, than comparing the area under the curve. These data confirmed that salivary cortisol is a good indicator to measure the HPA response to a stressor, provided that post-treatment levels can be compared with pre-treatment levels.     

Role of shame and body esteem in cortisol stress responses

Studies assessing the role of shame in HPA axis reactivity report mixed findings. Discrepancies may be due to methodological difficulties and inter-individual differences in the propensity to experience shame in a stressful situation. Hence, the current study combined self-report of shame and facial coding of shame expressions and assessed the role of body esteem as a moderator of the shame–stress link. For this, 44 healthy students (24F, age 20.5 ± 2.1 years) were exposed to an acute psychosocial stress paradigm (Trier Social Stress Test: TSST). Salivary cortisol levels were measured throughout the protocol. Trait shame was measured before the stress test, and state shame immediately afterwards. Video recordings of the TSST were coded to determine emotion expressions. State shame was neither associated with cortisol stress responses nor with body esteem (self-report: all ps ≥ .24; expression: all ps ≥ .31). In contrast, higher trait shame was associated with both negative body esteem (p = .049) and stronger cortisol stress responses (p = .013). Lastly, having lower body esteem predicted stronger cortisol stress responses (p = .022); however, it did not significantly moderate the association between shame indices and cortisol stress responses (all ps ≥ .94). These findings suggest that body esteem and trait shame independently contribute to strength of cortisol stress responses. Thus, in addition to trait shame, body esteem emerged as an important predictor of cortisol stress responses and as such, a potential contributor to stress-related negative health outcomes.
