Higher Levels Of Chronic Stress Research Articles

The impact of chronic stress on the hormonal state of women affected by hostilities and displaced women

During times of war, refugee women often have high levels of chronic stress due to factors such as war, displacement and uncertainty. The study focuses on examining the hormonal responses of female refugees experiencing chronic stress from war and displacement.The objective: to assess the impact of chronic stress caused by war and displacement on the hormonal balance of refugee women.Materials and methods. 60 women were examined, who were divided into groups: the 1st group included women who were affected by hostilities (20 persons), and the 2nd group included displaced women (20 individuals). In these 40 women the hormonal studies were conducted in the conditions of military aggression in Ukraine. The control group (3rd group) included healthy women who were examined in the pre-war period. All examined women were 20–25 years old with an average body weight of 55–60 kg. Concentrations of progesterone, estradiol, follicle-stimulating hormone (FSH) and luteinizing hormone, prolactin in the I and II phases of the menstrual cycle (MC), cortisol in the I phase of the MC were determined in blood serum using the enzyme immunoassay method. An analysis of the results of research on the role of the hypothalamic-pituitary-adrenal system in the regulation of the stress response was carried out.Results. In the examined women, various disorders of MC were observed, such as: menometrorrhagia, hypermenorrhea, acyclic uterine bleeding, oligomenorrhea, and amenorrhea. The most pronounced changes in menstrual function were observed in women who were affected by hostilities. Such significant disorders of MC in women of this group coincided with changes in indicators of gonadotropic hormones of the pituitary gland and sex hormones in the blood.A study of the psycho-emotional state of women who suffered from hostilities established that these women have a significant stressful effect of various risk factors on the body. Changes in the levels of cortisol, prolactin and other hormones were detected.Conclusions. Studies have shown that chronic stress affects the hormonal status of women affected by hostilities and of displaced women, including FSH, estradiol, and prolactin levels.A significant increase in the level of FSH in the follicular phase of the menstrual cycle and an increase in the level of estradiol in the luteal phase were determined, which may indicate a compensatory reaction of the body to stress. A significant increase in the level of prolactin was also found, which can cause disorders of menstrual function and affect the psycho-emotional state.

Abstract B154: Effect modification of United States residency and length of time in US on the relationship between allostatic load and cancer mortality risk in Hispanic/Latinx Americans: Insights from NHANES (1999-2019)

Abstract Allostatic load (AL) a measure of the cumulative physiological stress occurs when external stressors exceed an individual's ability to adapt, increasing the risk of chronic diseases, including cancer. In the United States (US), Hispanic/Latinx people face acculturation-related stressors like family separation, low socioeconomic status, language barriers, racism, and discrimination, which can elevate AL and cancer risk. This study aims to examine the moderating role of US citizenship status and length of time living in US on the relationship between high allostatic load and risk of cancer mortality among Hispanic/Latinx people. We performed a retrospective analysis using data from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2010 among 7,299 Hispanic/Latinx people linked with National Death Index with follow-up through December 31, 2019. We defined high AL as having more than three abnormal measures among the following nine biomarkers: body mass index, C-reactive protein, diastolic blood pressure, glycated hemoglobin, systolic blood pressure, total cholesterol, serum triglycerides, and serum creatinine (above the 75th percentile), or serum albumin (below the 25th percentile). We compared differences in participant characteristics using Rao-Scott Chi-Square tests for weighted survey data. We fit weighted Cox proportional hazards models to estimate hazard ratios and associated 95% confidence intervals of cancer death, stratified by US residence and length of time in US Among 7,299 Hispanic/Latinx people, 2,835 (33.4% weighted) had high AL, and 4,464 (66.6% weighted) had low AL. Hispanic/Latinx people with high AL were more likely to be male, aged 40-59, have a lower level of formal education (52.0% vs. 43.6%, p- value <0.001), and were more often surveyed during the 2007-2010 NHANES period (43.2% vs. 37.2%, p-value <0.001) compared to those with low AL. When considering US residency, participants with high AL were more likely to live in the US longer than 15 years (38.2% vs. 24.8%, p-value <0.001) and be US citizens (65.0% vs. 54.7%, p-value <0.001). Regarding health behaviors, participants with high AL were less likely to have been diagnosed with heart attack and less likely to have any history of smoking. We observed that among Hispanic/Latinx people, those with high AL have a 97% increased risk of dying from any cancer (HR = 1.97, 95% CI = 1.24 - 1.34) when compared to those with low AL. When stratifying by US citizenship status, among Hispanic/Latinx US citizen population those with high AL have a 2.3-times higher risk of cancer death when compared to those with low AL (HR = 2.30, 95% CI = 1.22 - 4.32). Among those who are Hispanic/Latinx non-US citizens, those with high AL have 48% increased risk of cancer death compared to those with low AL, though non-significant (HR = 1.48, 95% CI = 0.64 - 3.43). Our preliminary findings highlight that Hispanic/Latinx people with US citizenship who experience high levels of chronic stress, as measured by AL, have an increased risk of cancer mortality.

A U-shaped relationship between chronic academic stress and the dynamics of reward processing

Despite the potential link between stress-induced reward dysfunctions and the development of mental problems, limited human research has investigated the specific impacts of chronic stress on the dynamics of reward processing. Here we aimed to investigate the relationship between chronic academic stress and the dynamics of reward processing (i.e., reward anticipation and reward consumption) using event-related potential (ERP) technology. Ninety healthy undergraduates who were preparing for the National Postgraduate Entrance Examination (NPEE) participated in the study and completed a two-door reward task, their chronic stress levels were assessed via the Perceived Stress Scale (PSS). The results showed that a lower magnitude of reward elicited more negative amplitudes of cue-N2 during the anticipatory phase, and reward omission elicited more negative amplitudes of FRN compared to reward delivery especially in high reward conditions during the consummatory phase. More importantly, the PSS score exhibited a U-shaped relationship with cue-N2 amplitudes regardless of reward magnitude during the anticipatory phase; and FRN amplitudes toward reward omission in high reward condition during the consummatory phase. These findings suggest that individuals exposed to either low or high levels of chronic stress, as opposed to moderate stress levels, exhibited a heightened reward anticipation, and an augmented violation of expectations or affective response when faced with relatively more negative outcomes.

Early life stress and iron metabolism in developmental psychoneuroimmunology

An estimated 250 million children face adverse health outcomes from early life exposure to severe or chronic social, economic, and nutritional adversity, highlighting/emphasizing the pressing concern about the link between ELS and long-term implications on mental and physical health. There is significant overlap between populations experiencing high levels of chronic stress and those experiencing iron deficiency, spotlighting the potential role of iron as a key mediator in this association. Iron, an essential micronutrient for brain development and immune function, is often depleted in stress conditions. Iron deficiency among the most common nutrient deficiencies in the world. Fetal and infant iron status may thus serve as a crucial intermediary between early chronic psychological stress and subsequent immune system changes to impact neurodevelopment. The review presents a hypothesized pathway between early life stress (ELS), iron deficiency, and neurodevelopment through the hypothalamic-pituitary-adrenocortical (HPA) axis and the IL-6-hepcidin axis. This hypothesis is derived from (1) evidence that stress impacts iron status (2) long-term neurodevelopmental outcomes that are shared by ELS and iron deficiency exposure, and (3) possible mechanisms for how iron may mediate the relation between ELS and iron deficiency through alterations in the developing immune system. The article concludes by proposing future research directions, emphasizing the need for rigorous studies to elucidate how stress and iron metabolism interact to modify the developing immune system. Understanding these mechanisms could open new avenues for improving human health and neurodevelopment for women and children globally, making it a timely and vital area of study in psychoneuroimmunology research.

(127) TRAUMA INFORMED CARE TO REDUCE ANTEPARTUM COMPLICATIONS IN SURVIVORS OF TRAUMA

Abstract Introduction Life trauma permeates through society and across cultures. It impacts the individual, community, and society. Trauma may include but is not limited to adverse childhood experiences (ACEs), sexual assault and violence, domestic violence, and interpersonal violence (IPV). In the United States, 1 in 3 women experience physical IPV, 1 in 4 experience sexual assault, and 17% of adults have experienced 4 or more ACEs (CDC 2022, 2023). Experiencing trauma leads to a cascade of effects that infiltrate every aspect of life and causes higher levels of chronic stress. In those who are pregnant or giving birth, a history of trauma, particularly sexual assault, leads to adverse antepartum outcomes. Objective After this presentation, the learner will be able to: 1. Define trauma (ACEs, sexual assault, DV, IPV). 2. State the signs and symptoms of trauma. 3. Identify the antepartum complications associated with a history of trauma. 4. Explain the impact that a history of sexual assault has on the birth giver. 5. Define trauma informed care. 6. Identify the components of trauma informed care. 7. State the importance of using trauma informed care as a midwife and WHNP. Methods The methods used to address this topic include a literature review and podium style presentation of findings. Results Main findings include increased rates of miscarriage, preterm birth, post traumatic stress disorder, placental abruption, premature rupture of membranes, and low birth weight in pregnant survivors of past trauma. Additionally, the dynamic interplay between the Social Determinants of Health and violence experienced during pregnancy must be considered. Low household income, racism, lack of social support, as well as food and housing insecurity increased rates of intimate partner violence experienced during pregnancy. Trauma informed care has been shown to reduce psychological symptom severity and has been integrated into midwifery care to attempt to reduce these outcomes and prevent further traumatization of the client. Conclusions As pregnancy and childbirth are intimate and personal in nature, using a trauma informed model of care is crucial to identifying clients with trauma histories and caring for them in a manner that is cognizant of their lived experiences and potential antepartum outcomes. Future providers must receive adequate education and training regarding trauma informed care in an effort to prevent adverse outcomes and prevent re-traumatization of their clients. Disclosure No.

High perceived stress is associated with decreased sensory-specific satiety in humans

Previous studies have shown that chronic stress increases food intake. One possible mechanism may be due to altered sensory-specific satiety (SSS) among people with high level of chronic stress. In the current study, seventy-six participants were divided into either high-stress or low-stress groups according to their Perceived Stress Scale (PSS) scores. Participants were assigned to consume one of two foods (banana milk and corn soup) ad libitum until they felt comfortably satiated. Before and after eating, participants rated their liking and wanting for the flavor and the odor (via retronasal and orthonasal routes) of the eaten and uneaten foods. Individual interoceptive sensibility and eating behavior were measured using the Multidimensional Assessment of Interoceptive Awareness (MAIA) and Reasons Individuals Stop Eating Questionnaire (RISE-Q-15), respectively. Compared to the low-stress group, the high-stress group demonstrated blunted SSS to the whole food flavor. No significant difference was found for olfactory-specific satiety (retronasal or orthonasal) between the two groups. In addition, across the whole sample of participants, MAIA total score was positively associated with the magnitude of SSS (r = 0.29, p = 0.01). These results indicate that chronic perceived stress may play a role in the experience of reward during eating.

Inflammatory biotype of ADHD is linked to chronic stress: a data-driven analysis of the inflammatory proteome

The association between Attention Deficit Hyperactivity Disorder (ADHD) and low-grade inflammation has been explored in children but rarely in adults. Inflammation is characteristic of some, but not all, patients with ADHD and might be influenced by ADHD medication but also lifestyle factors including nutrition, smoking, and stress. It is also still unclear if any specific symptoms are related to inflammation. Therefore, we assessed 96 inflammatory proteins in a deeply phenotyped cohort of 126 adult ADHD participants with a stable medication status using OLINK technology. A data-based, unsupervised hierarchical clustering method could identify two distinct biotypes within the 126 ADHD participants based on their inflammatory profile: a higher inflammatory potential (HIP) and a lower inflammatory protein potential (LIP) group. Biological processes that differed strongest between groups were related to the NF-κB pathway, chemokine signaling, IL-17 signaling, metabolic alterations, and chemokine attraction. A comparison of sample characteristics revealed that the HIP group was more likely to have higher levels of chronic stress (p < 0.001), a higher clinical global impression scale score (p = 0.030), and a higher risk for suicide (p = 0.032). Medication status did not influence protein levels significantly (p ≥ 0.074), but psychotropic co-medication (p ≤ 0.009) did. In conclusion, our data suggest the presence of two distinct biotypes in adults with ADHD. Higher levels of inflammatory proteins in ADHD are linked to higher levels of chronic perceived stress in a linear fashion. Further research on inflammation in adults with ADHD should take stress levels into account.

Assessment of chronic stress in the adult population of the Vladimir region

Aim. To assess the prevalence of chronic stress in the adult population in the Vladimir region, taking into account sex characteristics.Material and methods. This cross-sectional population study was performed in five cities of the Vladimir Oblast (Vladimir, Kovrov, Murom, Yuryev-Polsky and Vyazniki) from May 2018 to March 2020. From six health care facilities, 9 therapeutic areas were selected. Then, from the assigned population aged 30-69 years, respondents from each area were invited to the study. To identify chronic stress, the Reeder questionnaire was used, which makes it possible to identify three types of disorders: low, moderate and severe stress. The study analyzed fully completed Reeder L. chronic stress questionnaires from 1081 respondents (393 men and 688 women).Results. Among men, every second person has a low chronic stress, 42% — moderate stress, while high chronic stress was found in 6.4% of cases. A similar trend is observed among women. High levels of chronic stress were detected in 8% of women, and the gap between the prevalence of low and moderate chronic stress was minimal. In general, the prevalence of various levels of chronic stress between men and women was comparable, without significant differences. Sex variability in the prevalence of chronic stress was revealed in various cities of the Vladimir Oblast. In Vladimir, the prevalence of high stress among men was three times higher than in women, while in Vyazniki and Kovrov the opposite pattern was observed. In the other two cities (Murom and Yuryev Polsky), the prevalence of high chronic stress between men and women was comparable.Conclusion. In the working-age population, a high chronic stress level is detected in up to 10%. In some cities, there are sex differences between men and women. The mean level of chronic stress is determined in 42-43% of cases. The results obtained indicate the need for large-scale preventive measures to combat chronic stress among working-age men and women of in the Vladimir Oblast.

Childhood overweight and obesity in Bariloche, Argentina: Beyond eating habits and physical activity.

The incidence of overweight and obesity is alarming worldwide. In Argentina, multifactorial studies are scarce despite the high rates of childhood overweight and obesity (OW/OB). In this study we assessed the prevalence of childhood OW/OB and the associated risk factors from a multicausal perspective: we analyzed sleep habits, screen use, chronic stress in children and their caregivers, social relationship problems, eating habits, and physical activity. Of the 397 first and seventh graders who completed the questionnaires, 41% had childhood OW/OB. In children with obesity, a lower level of physical activity, a lower consumption of protective foods, a higher risk for sleep disorders, higher levels of chronic stress (in both children and their caregivers), and higher rates of peer rejection were observed. Widespread use of screens before bedtime was noted in most children. This study evidences the diversity of factors associated with childhood OW/OB and highlights the convenience of a multidimensional approach to address it. In addition, the results of this study suggest the need to consider lifestyle habits as a preventive and therapeutic strategy for the management of OW/OB from early stages.

Perceived stress of mental demands at work, objective stress and resilience – an analysis of the LIFE-Adult-study

BackgroundSo far, previous research suggests positive effects of mental demands at the workplace. However, it may depend on how stressfull these demands are perceived on an individual level.ObjectiveThe aim was to build on previous research by investigating how mental demands are related to stress, overload, and work discontent and whether this relationship is mediated by individuals resources, such as resilience.MethodA sub-sample of the LIFE Adult Cohort (n = 480) was asked to answer questions on sociodemographic characteristics, objective stress (using the Trier Inventory of Chronic Stress (TICS)), and perceptions of stress with regard to verbal and executive mental demands at work.ResultsAccording to generalized linear regression models, higher verbal as well as executive mental demands were associated with higher levels of chronic stress, work overload and discontent. Higher levels of resilience were associated with lower levels of these outcomes. Analyses regarding interaction effects revealed that the interaction between resilience and perceived stress of verbal mental demands was significant only in terms of work overload.ConclusionHigher perceived stressfulness of mental demands was associated with higher chronic stress, work overload and work discontent. Therefore, mental demands should be targeted by occupational interventions that aim to improve job conditions and employees‘ overall well-being. Besides resilience, other potential influencers or personal resources should be focused on in future studies to develop interventions.

Examining the Associations of Early Childhood Teacher’s Emotional Well-being with Physiologic Stress, Mindfulness and Self-Compassion

Recent national reports indicate that early childhood (EC) teachers experience exceptionally high levels of chronic stress which can lead to adverse health outcomes. In this presentation, we share preliminary evidence of a mindfulness-based intervention, Cultivating Healthy Intentional Mindful Educators (CHIME) to support EC teachers’ regulatory processes. We hypothesize EC teachers’ social-emotional health is related to emotion regulation and their physiologic stress in the early care environment. EC teachers (n = 32 intervention, 22 waitlist control) recruited during 2020-2022 completed self-report measures of stress, well-being, mindfulness, and emotion regulation and task-based measures of emotional processing. Participants wore Actihearts (CamTech, Inc) to record their heart rate for three consecutive days in the classroom pre- and post-intervention. Controlling for pre-intervention metrics, the intervention group showed a tendency toward higher heart rate variability than controls post-intervention, F(1,44) = 3.84, p =.06. They also showed higher power in the high frequency heart rate band (F(1,44) = 3.92, p =.05) and lower average heart rate in the classroom (F(1,44) = 5.91, p =.02), despite showing similar activity levels to the control group, F(1,42) =.35, p =.56. There were significant differences in emotion dysregulation between the groups, with the CHIME group evidencing reduced emotion dysregulation, increased mental well-being, as well as differences in their response times during two emotional processing tasks, p’s <.05. Preliminary findings indicate that a mindfulness-based intervention is one promising way to support the emotional well-being of EC teachers.

Chronic stress and its correlates among nurses: A case of Central Uganda

Background: Despite an overwhelming disease burden, nursing shortages are evident in Sub-Saharan Africa, with the potential for significant healthcare crises. Nurses face increased work demands and chronic stress due to a skilled personnel shortage, which may lead to stress. The present study aimed to examine chronic stress and its correlates among nurses in central Uganda. Methods: The 12-item Short Form Survey (SF-12) for the assessment of chronic stress among nurses, a validated and standardized tool, was used in this cross-sectional study in 2022. For explanatory analysis, the items were combined with dichotomous variables reflecting predictors of chronic stress. These items were used to create dichotomous variables denoting frequent and demanding challenges for exploratory analysis. The relationship between the variables and high levels of chronic stress was investigated using a multivariate logistic regression model. Results: Based on the findings, the majority, 485 (76.0%), had chronic stress. The results indicate that the correlates of chronic stress among participants were widowhood (AOR: 0.040; 95% CI: 0.013-0.127; P= &lt;0.001), being worried about looming deadlines (aOR: 0.003; 95% CI: 0.001-0.023; P = &lt;0.001), long working hours (AOR: 0.283; 95% CI: 0.159-0.504; p=&lt;0.001), insufficient job control (AOR: 0.304; 95% CI: 0.127-0.727; P = 0.007), and inadequate rewards (AOR: 2.554; 95% CI: 1.170-5.574; P = 0.019). Conclusion: According to our findings, three in four nurses in central Uganda suffer from chronic stress. This can exert a negative impact on their overall well-being and caring behaviors. Chronic stress was associated with widowhood, a looming deadline, long working hours, insufficient job control, and inadequate rewards. It is critical to adapt interventions, such as hiring additional nurses, to reduce workload and ensure adequate rest periods.

Measuring Mindfulness in Black Americans: A Psychometric Validation of the Five Facet Mindfulness Questionnaire

Black Americans disproportionately experience higher levels of chronic stress. Mindfulness is a promising, cost-effective option for reducing stress and related mental health outcomes, such as depression and anxiety. The Five Facet Mindfulness Questionnaire (FFMQ) is one of the most widely used tools to measure mindfulness; however, Black American samples have been underrepresented in validation studies of the FFMQ. Consequently, the validity of the FFMQ within Black Americans has received minimal attention. The present study assessed the psychometric properties and nomological network of the original 39-item FFMQ (FFMQ-39) and the short form 15-item FFMQ (FFMQ-15) among a non-clinical, Black American sample in the United States. In a longitudinal study, 586 Black Americans completed either the FFMQ-39 or the FFMQ-15 at two time points one month apart, as well as measures of the constructs in mindfulness’ nomological network and demographic attributes. Exploratory and confirmatory factor analyses supported a 5-factor structure in both questionnaires. Both questionnaires had good fit indices (RMSEA < 0.06, SRMR < 0.08, CFI > 0.92, TFI > 0.92) and demonstrated strong test–retest reliability, expected associations with nomological network variables, and invariance across ethnic heritage, ethnic identity, everyday discrimination, lifetime discrimination, skin tone, depression level, gender, mindfulness meditation experience, and household income. The results indicate that both the FFMQ-39 and the FFMQ-15 can validly and reliably measure mindfulness in a non-clinical, Black American sample. These findings contribute to cultural generalizability and mindfulness assessment within underrepresented populations. The analytic plan was pre-registered on the Open Science Framework.

Perceptions of Stress and Mood Associated With Listening to Music in Daily Life During the COVID-19 Lockdown

Music listening is a universal human experience. People of all ages and cultures often use music to reduce stress and improve mood, particularly in times of crisis. However, ecologically valid research examining the real-time association of music listening with stress and mood during the COVID-19 pandemic is scarce. To explore the associations between listening to music and the perceptions of stress and mood using ecological momentary assessment during the COVID-19 lockdown period. In this cohort study conducted between April 1 and May 8, 2020, adults from the general population residing in Austria and Italy were prompted by an app on their smartphone to report data 5 times per day across 7 consecutive days. Participants provided data on their real-time and real-life experiences in their natural environment while strict lockdown measures were in place. Data analysis was performed from March 2021 to February 2022. Data on self-reported music listening were recorded by means of mobile-based assessments. Perceived chronic stress was assessed once at the end of the study. Perceptions of momentary stress and mood were measured using visual analog scales (score range, 0-100, where 0 indicates not at all and 100 indicates very much) by means of mobile app-based assessments. The final sample comprised 711 participants (497 women [69.9%]; median age, 27.0 years [IQR, 24.0-36.0 years]). Participants provided a total of 19 641 data points, including 4677 music listening reports. Music listening was prospectively associated with lower momentary stress levels (β, -0.92; 95% CI, -1.80 to -0.04; P = .04) and improvements in mood valence (β, 1.90; 95% CI, 1.17-2.63; P < .001), especially if the music was perceived as happy. Individuals with higher levels of chronic stress reported improved mood valence after music listening (β, 0.12; 95% CI, 0.02-0.22; P = .02). The present findings suggest that music listening may be a means to modulate stress and mood during psychologically demanding periods. Individuals experiencing heightened momentary and/or chronic stress because of the challenges brought about by COVID-19 pandemic-related restrictions might consider music as an easily accessible tool for the management of stress and mood in daily life.

The mane factor: Compliance is associated with increased hair cortisol in the horse

Equine personality tests enable the selection of horses for roles based on their habitual behavioural responses to challenges, aiming to maximise performance and safeguard equine welfare. However, existing research has identified that behavioural responses to acute challenges do not correlate well with stress physiology in the horse. The aim of this study was to investigate whether chronic stress physiology is related to habitual compliance in horses. Hair cortisol concentration (HCC), a long-term biomarker of hypothalamic–pituitary–adrenal axis activity and stress, was assayed in mane hair from the withers, midpoint of the neck and poll of 24 riding school horses (66% male, mean age 13 ± 4 years). Three caregivers provided scores for Agreeableness, Neuroticism, Extroversion, Gregariousness Towards People and Gregariousness Towards Horses for all subjects using a validated equine personality questionnaire. A gamma GLMM was used to model HCC as a function of personality scores and potential confounders of HCC (age, sex, hair colour and sampling location). Individual horses were fitted as random intercepts in the model. Manual backward selection was used to identify the best-fitting plausible model. Mean HCC was 3.8 ± 1.2 pg/mg. The final model only retained Agreeableness and sampling location as explanatory variables of HCC. A positive association was found between Agreeableness (reflecting habitual compliance) and hair cortisol concentration (t = 2.7, p = 0.01). Basal cortisol levels are known to drive sensitivity to punishment in humans. Therefore, horses with higher basal cortisol may be more sensitive to the aversive cues associated with negative reinforcement and consequently be more compliant. However, it is also possible that habitually compliant behaviour leads to higher chronic stress levels through increased exposure to stressors, as more subtle expressions of discomfort are not recognised by handlers. This result has important implications for welfare in the context of horse-human interaction and warrants further investigation to clarify whether a causal link exists between habitual compliance and higher levels of chronic stress. There was also a weaker but significant impact of sampling location (t = 2.1, p = 0.03; higher HCC at the poll), highlighting the importance of carefully standardizing sampling location for HCC analysis.

From the inside: Dancing between burnout and engagement in a prison.

Objectives: Professionals who work in prisons present high levels of chronic stress that affect their daily performance and health. The incorporation of training workshops on emotional regulation and stress coping strategies from a psycho-body approach could have a positive impact on their well-being. This article presents an exploratory study that analyzes chronic stress, emotional repertoire and body awareness, of a sample of 15 professionals from a prison, together with the effect produced by an intervention through training workshops with Dance Movement Therapy.Material and method: A mixed methodology with a pretest-posttest design was used. The variables of burnout, engagement, emotional repertoire and body awareness were measured. With the information obtained from a participatory focus group, a six-hour body awareness program was designed and implemented, during which participants completed reflective diaries for subsequent analysis.Results: High levels of stress and low body awareness were found. Qualitative analysis generated evidence for improvements in body awareness and the incorporation of coping strategies based on listening to body sensations and emotional regulation. Pre-post test analysis for a subsample (n = 4) of the total showed improvements in different subscales, not statistically significant, but with medium effect sizes.Discussion: Despite the limitations of the study, the results are promising. The participants value the workshop very positively and consider having incorporated tools to cope with work stress.

Stress Correlates Related to Depressive Symptoms Among Young Black Men in Southern California.

Black men experience higher levels of chronic stress, life stressors, and discrimination due to oppressive social and economic conditions. Black men are at greater risk of depression, but most published research on stress and depression has focused on Black people in general, Black women, or older Black men. We sought to determine whether discrimination, perceived stress, major life stress, daily hassles, and social capital were associated with depressive symptoms in young Black men. Survey data were collected from April 2010 to March 2012 in Southern California from a convenience sample of Black men (N = 201). We used two-sample t tests and one-way analysis of variance (ANOVA) to examine the association of stress correlates with depressive symptoms. Logistic regression was conducted to estimate the likelihood of reporting depressive symptoms for each significant correlate. Over half of the sample reported depressive symptoms. Health status, perceived discrimination, urban hassles, perceived stress, and neighborhood trust and safety were significantly related to depressive symptoms. Those who reported higher perceived stress had higher odds of reporting depressive symptoms, whereas lower everyday discrimination experiences were associated with lower odds of depressive symptoms. Future studies should consider examining the effectiveness of embedding coping mechanisms for stress, including perceived discrimination, in health interventions for young Black men to prevent or reduce depression.

Is Silence Golden? Chronic Stress and Psychophysiological Indicators’ Changes over Time in International Students: A Pilot Study

Most people assume studying or working abroad would be stressful - but would one ever think that it could be detrimental to the health? Stress literature relates cross-cultural transactions to the chances of gaining higher levels of chronic stress. This paper reports the results of two studies on international students in Moscow in 2018. Specifically, Study 1 assessed how cross-cultural transactions perceived to affect health state during the first 6 months of their relocation. Study 2 aimed to investigate if the psychological stress linked to relocation to a different country can possibly lead to psychobiological effects of chronic stress. In Study 1, qualitative methods were applied to conduct 21 interviews with international students. In Study 2, a longitudinal pilot study was conducted for 10 foreign students during the first 2-5 (M = 3.6) months of their relocation. Stress related to cross-cultural transactions was expected to affect subjective well-being and health variables. The health state was a relatively silent topic in the interview participants of Study 1. The results of Study 2 showed that the participants had changes in the resting heart rate (RHR) baseline. Perceived chronic stress related to cross-cultural transactions may affect psychophysiological state; however, the affect varies depending on a person. Further research is required for the data consistency and for identifying non-invasive objective risk markers and individual stress pathways, with the goal of identifying at-risk students and providing treatment options before any serious harm is done to their health.

Disparities in allostatic load, telomere length and chronic stress burden among African American adults: A systematic review

BackgroundThe chronic disease burden among African Americans has continued to rise. Although racial disparities in chronic disease risk are well documented, the role of chronic stress in risk disparities among racial and ethnic minorities is not well understood. This systematic review of studies reporting on the relationship between chronic stress, education, and/or income, and biomarkers of chronic stress (allostatic load and telomere length) longitudinally among African Americans, seeks to contribute to this knowledge gap. ObjectiveTo use the existing literature to both examine the strength of two objective biomarkers--telomere length and allostatic load--as measures of the overactivation of physiological stress processes in African American adults; and determine if existing studies used these two biomarkers to assess the relationship between chronic stress, income and level of educational attainment among African Americans longitudinally. MethodsIn order to identify English-language articles published prior to October 11, 2021, a comprehensive search strategy was developed using five databases: PubMed/Medline, EMBASE, Web of Science Plus, Global Health (Ovid), and PsycINFO. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method was used to record progress on the comprehensive search for studies reporting on allostatic load and/or telomere length biomarkers longitudinally within all bodily fluids and chronic stress among African American adults. ResultsIn total, 7 studies met the search criteria; 902 were excluded. Thus, less than 1% of all studies reporting on biomarkers of chronic stress longitudinally included African Americans. Each of the 7 studies described the relationship between telomere length and/or allostatic load among African Americans and chronic stress, education, and/or income. Higher chronic stress levels and experiences of racial discrimination were associated with telomere shortening while lower income and higher chronic stress levels were associated with an increase in allostatic load among African Americans. DiscussionGiven the limited number of studies reporting on the association between allostatic load, telomere length, and/or the relationship between both in assessing chronic stress severity longitudinally among African American populations, it is impossible to determine whether one biomarker has greater predictive value than the other. However, based on the literature included in this review, higher chronic stress levels and experiences of racial discrimination were associated with shorter telomere length, while lower income and higher chronic stress levels are associated with an increase in allostatic load among African Americans. ConclusionThese data illustrate a gap in the literature on the relationship between the biomarkers of telomere length and allostatic load combined as a potential measure for chronic stress among African Americans. To our knowledge, none the current literature describes the relationship between telomere length and allostatic load longitudinally among African American adults. As the field strives to develop a “gold standard” for measuring chronic stress, the combination of these biomarkers needs to be the subject of scientific inquiry and thus, fully examined. Future longitudinal studies among African Americans are needed to better understand which biomarker, or combination of biomarkers will provide the most accurate measure of physiological stress processes.
