Unemployment as a chronic stressor: A systematic review of cortisol studies

Prevalence of hysterectomy and its determinants in northern Iran: enrollment results of the Tabari cohort study

BACKGROUND

To the best of our knowledge, no population-based studies have provided insights into the prevalence of hysterectomy and its risk factors among northern Iranian females. Thus, the present study aimed to investigate the prevalence and sociodemographic determinants of hysterectomy in a large cohort of northern Iranian females.

METHODS

This cross-sectional study included data from the enrollment phase of the Tabari cohort study (TCS). The TCS consists of 10,255 adults (4,149 males and 6,106 females) aged 35-70 years who reside in Sari, Mazandaran, Iran, of which 6103 females were included in the study. Multiple logistic regression analysis was used to search for hysterectomy determinants.

RESULTS

Our results revealed that the prevalence of hysterectomy among northern Iranian females was 9.7% (595/6103). Additionally, 50-59 (OR: 4.63, 95% CI: 3.57-6.01) and 60-70 (OR: 5.83, 95% CI: 4.28-7.95) age groups, higher socioeconomic levels (OR: 1.66, 95% CI: 1.13-2.42), a history of tubectomy (OR: 1.27, 95% CI: 1.05-1.53), and more gravida (OR: 5.35, 95% CI: 1.62-17.63) were found to increase the odds of hysterectomy, whereas living in mountainous areas (OR: 0.57, 95% CI: 0.43-2.75) and having a job (OR: 0.62, 95% CI: 0.45-0.86) were found to decrease the odds of hysterectomy.

CONCLUSION

Older age groups, living in urban areas, higher socioeconomic levels, not having a job, a history of tubectomy, and more gravida were found to increase the odds of hysterectomy.

Job loss during pregnancy and the risk of miscarriage and stillbirth

STUDY QUESTION

Does the exposure to job loss during pregnancy increase the risk of miscarriage or stillbirth?

SUMMARY ANSWER

The experience of own or partner's job loss during the pregnancy is associated with an increased risk of miscarriageand stillbirth.

WHAT IS KNOWN ALREADY

Prior research on the psycho-social aspect of pregnancy loss has investigated the contextual and the individual-level stressors. At the contextual level, natural disasters, air pollution, and economic downturns are associated with higher risk of pregnancy loss. At the individual level, intense working schedules and financial strain are linked with increased risk of pregnancy loss both at early and later stages of the gestation.

STUDY DESIGN, SIZE, DURATION

This work draws on high-quality individual data of 'Understanding Society', a longitudinal survey that has interviewed a representative sample of households living in the UK annually since 2009. Approximately 40 000 households were recruited. The analyses use all the available survey waves (1-12, 2009-2022).

PARTICIPANTS/MATERIALS, SETTING, METHODS

The final sample consisted of 8142 pregnancy episodes that contain complete informationon pregnancy outcome and date of conception. Ongoing pregnancies at the time of the interview were excluded from the final sample. The outcome variable indicated whether a pregnancy resulted in a live birth or a pregnancy loss whereas the exposure variable identified the women's or their partner's job loss because of redundancy or a dismissal. Logistic regression models were employed to estimate the relation between job loss during pregnancy and pregnancy loss. The models were adjusted for an array of socio-demographic and economic characteristics following a stepwise approach. Several sensitivity analyses complemented the main findings.

MAIN RESULTS AND THE ROLE OF CHANCE

Baseline models controlling for women's demographic background and prior experience of miscarriage estimated an increased risk of pregnancy loss when women were exposed to their own or their partner's job loss during their pregnancy (odds ratio (OR) = 1.99, 95% CI: 1.32, 2.99). When the models were adjusted for all socio-economic and partnership-related covariates the association remained robust (OR = 1.81, 95% CI: 1.20, 2.73).

LIMITATIONS, REASONS FOR CAUTION

First, the pregnancy outcome and the date of conception were self-reported and may besubjected to recall and social desirability bias. Second, although we adjusted for an array socio-demographic characteristics and self-reported health, other contextual factors might be correlated with both job loss and pregnancy loss. Third, owing to the limited sample size, we could not assess if the main finding holds across different socio-economic strata.

WIDER IMPLICATIONS OF THE FINDINGS

By showing that exposure to a job loss during pregnancy increases the risk of miscarriage and stillbirth, we underline the relevance of pregnancy loss as a preventable public health matter. This result also calls for policy designthat enhances labour market protection and social security buffers for pregnant women and their partners.

Predictors of Health in Substance Use Disorder Recovery: Economic Stability in Residential Aftercare Environments

The exit from active substance use presents barriers to achieving and maintaining health, especially as individuals lack the economic resources to afford healthcare access. Treatment settings that strengthen resources may support stability in recovery and influence health. Analyzing a sample of recovery home residents over two years (N = 494), the current study assessed individually held resources (e.g., wages, employment) and the average economic conditions of a resident's house (e.g., house employment rate) to understand their association with self-reported health status. Employment status, but not wages or transportation access, was associated with reported health scores. The average employment rate of a recovery home was also positively correlated with the health of its residents. Results indicate the need to address employment and other economic issues which plague recovering individuals. Community aftercare settings may offer such a pathway through affordable housing, employment opportunities, and supportive relationships.

Unemployment and hair cortisol as a biomarker of chronic stress

Unemployment is widely considered an important chronic stressor. Using longitudinal data of initially employed German jobseekers, the present study examines whether unemployment is related to changes in hair cortisol concentration (HCC), a reliable biomarker for chronic stress. The results indicate that HCC is the highest initially when individuals are insecurely employed and decreases as people gain certainty about whether they enter unemployment or not. We find no effects when comparing the average changes in HCC between individuals who entered unemployment to those of continuously employed individuals. However, medium-term unemployment was associated with a stronger mean increase in HCC if re-employment expectations were low compared to when re-employment expectations were high. Taken together, our results support two key conclusions. First, experiencing the uncertainty of looming unemployment is associated with more pronounced cortisol secretion than unemployment itself. Second, whether working or being unemployed is associated with higher HCC is highly context-dependent, with poor re-employment prospects during unemployment being a key predictor of increased HCC. Overall, our study provides further evidence that the physiological stress system is especially sensitive to uncontrollable situations and unfamiliar challenge.

Perceived loss of resources and adherence to guidelines during the COVID-19 pandemic in Israel

Following the outbreak of the global COVID-19 pandemic, governments around the world issued guidelines designed to prevent contagion. This longitudinal study explored variables associated with citizens' adherence to these guidelines. Questionnaires were administered to a panel of Israeli citizens three times: in June (Time 1, n = 896), July (Time 2, n = 712) and August (Time 3, n = 662) 2020. The relationships of perceived loss of resources (e.g. stable employment) at Time 1 with adherence to guidelines at Time 2 and Time 3 were moderated by assumptions about controllability: The relationships were stronger for people who believed that appropriate behavior would lead to positive outcomes and prevent negative outcomes. The results indicate that messages about the pandemic should be accompanied by encouraging messages regarding the ability to control.

Adverse childhood experiences and diurnal cortisol patterns in older people in England

Adverse childhood experiences (ACE) are associated with HPA axis dysregulation at younger ages, but there is scarcity of evidence for this association at older ages. To add to our knowledge of the lifetime impact of ACE on HPA axis function, we examined whether ACE were associated with diurnal cortisol patterns in a national sample of 587 participants (356 women) aged 55-79 years from the English Longitudinal Study of Ageing (ELSA). We conducted descriptive analyses and estimated sex-specific robust regression models of the associations between the 8-item summary ACE score and four measurements of salivary cortisol over a 24-h cycle (upon waking, 30 min later, at 7 pm, and at bedtime) as well as the cortisol awakening response (CAR) and the diurnal cortisol slope. Our models were adjusted for age, then for childhood socioeconomic position and finally for adult socioeconomic position. In men, we found significant differences that were independent of covariates, with more ACE being associated with lower salivary cortisol levels on waking, a greater CAR, and a flatter diurnal cortisol slope. In women, we observed a graded association between ACE and increased 7 pm salivary cortisol levels. Our findings indicate that childhood adversity is related to HPA axis in older people, especially men. The chronological distance (on average >50 years) between ACE and salivary cortisol levels suggests the existence of a lifelong association between childhood adversity and HPA axis and neuroendocrine function. Notwithstanding sex differences, based on our findings we suggest that HPA axis dysregulation could be a pathway that mediates the association between ACE and chronic disease later in life.

Feasibility of Work-Related Interviewing and Conversational Skills Trainings for Individuals With Psychiatric Disabilities

This study examined the feasibility of group interventions using the Direct Skills Teaching (DST) approach to teach interview preparedness skills (“Presenting Qualifications”) and basic work-related conversational skills (“Conversing with Others”) to individuals with psychiatric disabilities. This quasi-experimental pilot study included 87 participants in Study 1 and 55 participants in Study 2, all with various psychiatric diagnoses. Each group intervention consisted of four sessions delivered by graduate counseling students. Participants reported increased confidence in presenting qualifications at interviews in Study 1, and in conversational skills at work in Study 2. Participants in both studies reported high levels of satisfaction with the respective group intervention. The results of the study supported the feasibility of DST group interventions designed to teach work-related skills to individuals with psychiatric disabilities.

Does unemployment lead to greater levels of loneliness? A systematic review

There is evidence that loneliness and unemployment each have a negative impact on public health. Both are experienced across the life course and are of increasing concern in light of the COVID-19 pandemic. This review seeks to examine the strength and direction of the relationship between loneliness and unemployment in working age individuals, and in particular the potential for a self-reinforcing cycle with combined healthcare outcomes. A systematic search was undertaken in Medline, PubMed, PsycINFO, Embase and EconLit from inception to December 2020. PRISMA reporting guidelines were followed throughout this review, study quality was assessed using the Joanna Briggs Institute checklist and results were summarised in a narrative synthesis. English language studies evaluating the relationship between loneliness and unemployment in higher income western countries were included. Thirty-seven studies were identified; 30 cross-sectional and 7 longitudinal. Loneliness was measured by a direct question or loneliness scale while unemployment was self-reported or retrieved from a national register. A positive association between unemployment and increased loneliness was observed across all studies. Thus, across the life-course a clear yet complex relationship exists between unemployment and greater experience of loneliness. The magnitude of this relationship increases with the severity of loneliness and appears to peak at age 30-34 and 50-59. Logistic regression provided the greatest consistency at statistical significance revealing at least a 40% increase in the likelihood of reporting loneliness when unemployed. Recent longitudinal studies identified in this review found higher levels of loneliness following job loss, but also that loneliness was predictive of unemployment suggesting potential bi-directionality in the relationship. This bi-directionality may create a multiplier effect between loneliness and unemployment to form a self-reinforcing relationship and greater health concerns for those most at risk. Thus, review findings suggest the need for cross-sector awareness and intervention to tackle both loneliness and unemployment.

Precarious Employment and Stress: The Biomedical Embodiment of Social Factors. PRESSED Project Study Protocol

The PRESSED project aims to explain the links between a multidimensional measure of precarious employment and stress and health. Studies on social epidemiology have found a clear positive association between precarious employment and health, but the pathways and mechanisms to explain such a relationship are not well-understood. This project aims to fill this gap from an interdisciplinary perspective, integrating the social and biomedical standpoints to comprehensively address the complex web of consequences of precarious employment and its effects on workers' stress, health and well-being, including health inequalities. The project objectives are: (1) to analyze the association between multidimensional precarious employment and chronic stress among salaried workers in Barcelona, measured both subjectively and using biological indicators; (2) to improve our understanding of the pathways and mechanisms linking precarious employment with stress, health and well-being; and (3) to analyze health inequalities by gender, social class and place of origin for the first two objectives. The study follows a sequential mixed design. First, secondary data from the 2017 Survey on Workers and the Unemployed of Barcelona is analyzed (N = 1,264), yielding a social map of precarious employment in Barcelona that allows the contextualization of the scope and characteristics of this phenomenon. Drawing on these results, a second survey on a smaller sample (N = 255) on precarious employment, social precariousness and stress is envisaged. This study population is also asked to provide a hair sample to have their levels of cortisol and its related components, biomarkers of chronic stress, analyzed. Third, a sub-sample of the latter survey (n = 25) is selected to perform qualitative semi-structured interviews. This allows going into greater depth into how and why the experience of uncertainty, the precarization of living conditions, and the degradation of working conditions go hand-in-hand with precarious employment and have an impact on stress, as well as to explore the potential role of social support networks in mitigating these effects.

Social and Psychophysiological Consequences of the COVID-19 Pandemic: An Extensive Literature Review

The Coronavirus Disease 2019 (COVID-19) pandemic, now a global health crisis, has surprised health authorities around the world. Recent studies suggest that the measures taken to curb the spread of the COVID-19 outbreak have generated issues throughout the population. Thus, it is necessary to establish and identify the possible risk factors related to the psychosocial and psychophysiological strain during the COVID-19 outbreak. The present extensive literature review assesses the social, psychological, and physiological consequences of COVID-19, reviewing the impact of quarantine measures, isolation, vast human loss, social and financial consequences in the family's economies, and its impact on the psychological health of the population. We also discussed the effect of psychophysiological factors, considering the impact of physical inactivity and modifications in nutritional habits, at psychological and physiological levels. The present review includes an actualized to date bibliography, articles for which were methodologically analyzed to verify they met the standards of quality and scientific accuracy. Authors understand the pandemic as a multifactorial event for which only a profound and extensive analysis would lead to better compression and efficient intervention in the near future.

Unemployment, employment precarity, and inflammation

Unemployment has been associated with poorer health, but few studies have examined the biological mechanisms that confer these health decrements. Further, no studies to date have examined differences across employment groups to consider whether employment (in whatever means) is preferential in terms of health. The present study utilised secondary data from Understanding Society: The Household Longitudinal Survey during the aftermath of the recent global recession. Two markers of peripheral inflammation: C-reactive protein (CRP) and fibrinogen were assessed across employment groups (unemployed; permanent, temporary, and self-employed), controlling for individual, socio-demographic and health variables to give greater context to our understanding of how employment status influences health. After controlling for relevant confounds, unemployment was associated with higher levels of fibrinogen but not CRP. Subsequent analyses of employment subgroup revealed the temporary employed have similar levels of fibrinogen to the unemployed, and may therefore be at a similar health disadvantage. The findings confirm that unemployment is associated with increases in one marker of peripheral inflammation, but that this health protection is not conferred to those in precarious employment.

Living in the shadow of unemployment -an unhealthy life situation: a qualitative study of young people from leaving school until early adult life

Background

Despite the magnitude of youth unemployment there is a lack of studies, which explore the relations between health experiences and labour market position in various contexts. The aim of this paper was to analyse health experiences among young people in NEET (not in education, employment or training) in relation to labour market position from leaving school until early adult life.

Method

The population consists of everyone (six women, eight men) who became unemployed directly after leaving compulsory school in a town in Northern Sweden. Repeated personal interviews were performed from age 16 until age 33. The interviews were analysed using qualitative content analysis.

Results

Health experiences can be viewed as a contextual process, related to the different phases of leaving school, entering the labour market, becoming unemployed and becoming employed. Perceived relief and hope were related to leaving compulsory school, while entering the labour market was related to setbacks and disappointments as well as both health-deteriorating and health-promoting experiences depending on the actual labour market position. Our overarching theme of “Living in the shadow of unemployment – an unhealthy life situation” implies that it is not only the actual situation of being unemployed that is problematic but that the other phases are also coloured by earlier experiences of unemployment .

Conclusion

A focus on young people’s health experiences of transitions from school into the labour market brings a new focus on the importance of macroeconomic influence on social processes and contextualised mechanisms from a life-course perspective.

The Impact of Parental Role Distributions, Work Participation, and Stress Factors on Family Health-Related Outcomes: Study Protocol of the Prospective Multi-Method Cohort "Dresden Study on Parenting, Work, and Mental Health" (DREAM)

The Dresden Study on Parenting, Work, and Mental Health (“DResdner Studie zu Elternschaft, Arbeit, und Mentaler Gesundheit”, DREAM) aims to prospectively investigate the relationship between parental work participation, role distribution, stress factors, and their effects on perinatal outcomes and long-term family mental and somatic health in a community sample targeting N = 4,000 individuals, i.e., 2,000 couples, expecting a child and residing in Dresden, Germany (interim sample of N = 1,410 participants, recruitment ongoing). Various questionnaires are completed at four measurement points from pregnancy to 2 years postpartum (prolongation into middle childhood planned). Applying a multi-method approach, long-term endocrinological data (analyses of hair cortisol concentrations and other endogenous hormones, “DREAM_HAIR”) and qualitative interview data (regarding gender role attitudes and distribution of domestic work, child care, and paid employment; “DREAM_TALK”) are obtained. In this study protocol, the theoretical background, methods, and preliminary results considering sociodemographic characteristics during pregnancy and birth-related factors at 8 weeks postpartum are presented. Additionally, there is a focus on our endocrinological sub-study DREAM_HAIR. In this sub-study currently comprising N = 152 participants, i.e., 88 families (recruitment ongoing), we want to gain knowledge on the transgenerational processes of stress regulation and psychopathology in the whole family by analyzing hair cortisol concentrations in both parents and children during the course from pregnancy (or after birth regarding children) to at least 2 years postpartum. By comparing data of the community sample to a clinical sample of mothers with postpartum mental disorders, their children, and their partners during the period between admission and discharge from a mother-baby unit and post-treatment (“DREAM_MBU”), the course of mothers' psychopathology, parent-infant interaction, and infant regulation disorders with special regard to long-term endocrine correlates will be examined. With previous studies neglecting the fathers or partners involved, a major advantage of DREAM is the use of a multi-method and multi-level approach by examining the whole family in a longitudinal design. Therefore, the DREAM study will contribute to a better understanding of the role of social, work, and stress factors for mental and somatic health and its long-term endocrine correlates in the natural course of becoming a family.

Endocrine Modulation in Long-Term Karate Practitioners

Purpose

Karate is a martial arts discipline which is widely practiced in the Western world as a form of self-defense, as well as a discipline to achieve physical and mental balance. However, little is known with respect to its specific psychobiological effects, particularly in relation to the influence that it may exert on the endocrine system. Thus, in the present study, we examined the effects of karate on several hormonal parameters of the Hypothalamic-Pituitary-Adrenal and Hypothalamic-Pituitary-Thyroid axes in long-time practitioners.

Methods

Twenty-two healthy volunteer subjects (12 experimental and 10 controls) participated in the study. Experimental subjects were karate players with a minimum of 3 years of practice in this discipline. Blood samples for the quantification of hormonal parameters were taken in both groups. The Mann-Whitney U test was performed for each variable in order to analyze the differences between groups.

Results

Statistically significant differences were found in cortisol and thyroid hormones, with the karate group showing lower levels of these hormones as compared to control.

Conclusions

These findings, therefore, reveal that long-term karate practice is associated with a significant endocrine modulation, which suggests interesting psychobiological and clinical implications. Further research is needed to verify these preliminary results, as well as properly assessing its possible use as a psychosomatic intervention tool.
