Changes in financial strain over three years, ambulatory blood pressure, and cortisol responses to awakening

Understanding Momentary Alcohol Use Cognitions Through the Lenses of Momentary Socioeconomic Identification, Unfair Treatment, and Strain

BACKGROUND

Studies suggest that socioeconomic status (SES) is related to alcohol use. SES may impact alcohol use via exposures to financial stress, discriminatory experiences, identity threats, negative emotions, and perceived threats. These experiences could lead to alcohol use via increases in alcohol use willingness. However, there is little research using ecological momentary assessment (EMA) to illuminate temporal dynamics in the relationship between SES and alcohol use willingness during daily life moments. This is especially important to examine in emerging adults, given their unique developmental stage.

METHODS

A sample of 119 African American emerging adults (mean age = 24.82, 59% female, diverse educational levels) completed 4 d of EMA surveys reporting both SES-related experiences and alcohol use willingness on an hourly basis.

RESULTS

Higher perception of SES-based unfair treatment was found to be linked with a greater willingness to drink at the moment (p < .001, b = 0.66). Conversely, a positive view of one's own SES at the moment was associated with a lower willingness to drink (p < .001, b = -0.12). Additionally, a heightened perception of perceived threat at the moment was associated with a higher willingness to drink (p = .001, b = 0.05).

CONCLUSION

SES-based unfair treatment and positive identification are factors that influence spontaneous alcohol use interest among emerging adults. Clinicians should assess these SES factors when attempting prevention and treatment, especially momentary interventions. Further, research should investigate more mechanisms explaining associations between SES-based unfair treatment and willingness to use other substances.

Associations Between Perceived Stress and Cortisol Biomarkers in Predominantly Latino Adolescents

Objective

The relationship between cortisol and perceived stress is poorly understood. We sought to determine whether perceived stress is associated with cortisol biomarkers in adolescents.

Methods

We examined 229 adolescents (mean age = 15.8 years). We measured perceived stress with the 14-item Perceived Stress Scale (PSS) questionnaire, serum cortisol (sCOR), salivary Cortisol Awakening Response (CAR: 30-minute post-awakening - awakening), salivary Diurnal Cortisol Slope (DCS: evening-awakening), and total daily salivary cortisol (TDC). We used multivariable linear regression to estimate baseline associations between PSS, TDC, sCOR, and FBG. We used mixed effects linear regression to estimate baseline associations between PSS and CAR and DCS. We tested twelve-week longitudinal associations between PSS and cortisol biomarkers using random effects regression. Analyses were adjusted for age, gender, and BMI.

Results

There were statistically significant associations between PSS and TDC (beta= -104.36 ± 34.3; p = 0.002) at baseline and between PSS and DCS at 12 weeks (beta= -0.058 ± 0.02; p = 0.01), but no association between PSS and sCOR or CAR (p > 0.26 for all) at baseline or 12-weeks. There were no associations between change in PSS and change in cortisol biomarkers longitudinally.

Conclusion

In adolescents, perceived stress measured by the PSS was inconsistently associated with TDC and DCS, and consistently unassociated with CAR and sCOR. Studies reporting on PSS outcomes should exercise caution when making conclusions about cortisol biomarkers. There's a need for an instrument that captures a global measure of perceived stress and is sensitive to HPA functioning.

The impact of the COVID-19 pandemic on the socioeconomic gradient of hypertension

The COVID-19 pandemic has brought into sharp focus the impact of socioeconomic factors on hypertension outcomes. This review examines the implications of the pandemic on the socioeconomic gradient of hypertension and explores the physiological and pathophysiological processes underlying this relationship. Changes in socioeconomic factors have disproportionately affected individuals with lower socioeconomic status, leading to adverse hypertension outcomes. The pandemic-related stressors, coupled with social isolation and disrupted daily routines, have contributed to elevated stress levels among individuals, particularly those with lower socioeconomic status. Equitable access to healthcare, enhancing health literacy and patient empowerment, and addressing social determinants of health are essential components of hypertension management strategies. By recognizing the specific challenges faced by individuals with lower socioeconomic status and implementing targeted interventions, public health efforts can help reduce the socioeconomic gradient of hypertension.

Financial responsibility, financial context, and ambulatory blood pressure in early middle-aged African-American women

BACKGROUND

African-American women have excess rates of elevated blood pressure (BP) and hypertension compared to women of all other racial/ethnic backgrounds. Several researchers have speculated that race and gender-related socioeconomic status (SES) stressors might play a role.

OBJECTIVE

To examine the association between a novel SES-related stressor highly salient among African-American women, financial responsibility for one's household, and 48-h ambulatory BP. We further examined whether aspects related to African-American women's financial context (e.g., single parenthood, household income, marital status) played a role.

METHODS

Participants were N = 345 employed, healthy African-American women aged 30-46 from diverse SES backgrounds who underwent 48-h ambulatory BP monitoring. Linear regression analyses were conducted to examine associations between self-reported financial responsibility and daytime and nighttime BP, adjusting for age, SES and other sociodemographics, cardiovascular risk factors, financial strain and depressive symptoms. Interactions between financial responsibility and single parenthood, household income, and marital/partnered status were tested.

RESULTS

In age-adjusted analyses, reporting financial responsibility was associated with higher daytime systolic (β = 4.42, S.E. = 1.36, p = 0.0013), and diastolic (β = 2.82, S.E. = 0.98, p = 0.004) BP. Associations persisted in fully adjusted models. Significant associations were also observed for nighttime systolic and diastolic BP. There were no significant interactions with single parenthood, household income, nor marital/partnered status.

CONCLUSION

Having primary responsibility for one's household may be an important driver of BP in early middle-aged African-American women, independent of SES, financial strain, and across a range of financial contexts. Future studies examining prospective associations are needed, and policy interventions targeting structural factors contributing to financial responsibility in African-American women may be warranted.

The Percentage of Patients Experiencing Financial Strain Depends on the Screening Measure: Evidence From a Cross-Sectional Survey of Adult Members of an Integrated Healthcare Delivery System

OBJECTIVES

Financial strain has important consequences for patients, providers, and health care systems. However, there is currently no gold standard measure to screen for financial strain. This study compared the performance of 3 single-item screeners using a composite measure of financial strain as a "gold standard."

METHODS

We conducted a secondary analysis of unweighted data from a 2021 survey of Kaiser Permanente Northern California health plan members comparing the percentages of adults who experienced financial strain based on 3 general single-item screeners, a screener specific to medical and dental health care use, and a composite financial strain measure. The study sample was comprised of 2734 non-Medicaid insured adults who answered all financial strain questions. Kappa statistics evaluating agreement of the 3 general screeners with the composite measure were calculated for the sample overall, by age group, and within age group, by 4 levels of income and 4 racial/ethnic subgroups.

RESULTS

Among 947 adults aged 35 to 65, 30.7% had just enough money or not enough money to make ends meet, 23.3% had a somewhat hard or hard time paying for basics, 18.8% had trouble paying for ≥1 type of expense, 20.5% had delayed/used less medical/dental care, and 41.5% had experienced financial strain based on the composite measure. Among 1787 adults aged 66 to 85, the percentages who screened positive on these measures were 22.7%, 19.4%, 12.9%, 19.8%, and 34.4%, respectively. Across the sample, by income categories and racial/ethnic groups, the making ends meet screener identified higher percentages of adults experiencing financial strain and performed better when compared with the composite measure than the hard to pay for the very basics and trouble paying for expenses screeners. Overall, substantial decreases in the percentages of adults who screened positive on the financial strain measures were seen as level of income increased. Within income categories, middle-aged adults were more likely than older adults to have experienced financial strain based on the composite and general single-item screeners.

CONCLUSIONS

As social risk screening becomes part of the standard of care, it will be important to assess how well different brief screeners for financial strain perform with diverse patient populations.

The Modern Environment: The New Secondary Cause of Hypertension?

The most important risk factor for cardiovascular disease, the leading cause of death worldwide, is hypertension. Although most cases of hypertension are thought to be essential, the multifactorial associations of the environmental influence on blood pressure seem to play an important role and should be more closely investigated. This review attempts to focus on the recent literature that examines the environmental effects on arterial blood pressure and its management. Seasonal variability and the role of ambient temperature, either occupational or recreational noise pollution, as well as obesity due to environment-caused dietary habits, are recognized as important risk factors, affecting the onset as well as the regulation of hypertension. Furthermore, the effects of seasonal fluctuations in blood pressure, noise pollution, and obesity seem to share a similar pathogenesis, and as such to all further react together, leading to increased blood pressure. The activation of the autonomous nervous system plays a key role and causes an increase in stress hormones that generates oxidative stress on the vascular system and, thus, vasoconstriction. In this review, by focusing on the association of the environmental impact with arterial blood pressure, we come to the question of whether most cases of hypertension-if not all-should, indeed, be considered primary or secondary.

Hair Cortisol Concentration as a Biomarker of Symptoms of Depression in the Perinatal Period

Pregnancy is a sensitive period when women experience major hormonal and psychological changes. A high prevalence of the symptoms of depression and manifested major depression rates have been reported during this period, leading to negative outcomes both for mothers and the offspring. Despite its prevalence, the aetiology of depression is not yet fully understood. Nonetheless, alterations in cortisol levels have been proposed as a reliable biomarker to identify pregnant women at risk of perinatal depression. Hair cortisol has recently been extensively used in bio-psychological studies as a suitable non-invasive biomarker for several neuropsychiatric disorders. Various studies have published evidence regarding the relationship between cortisol fluctuations during the perinatal period, measured both in hair and in other substrates, and the onset of perinatal symptoms of depression. This current review provides an overview of cortisol level changes measured in women's hair during pregnancy or the postpartum period and its association with perinatal symptoms of depression. Further studies, including repetitive measurement of both hair cortisol and depression throughout the prenatal period, must be performed to clarify the relationship between cortisol levels and perinatal symptoms of depression.

Socioeconomics and Erotic Inequity: A Theoretical Overview and Narrative Review of Associations Between Poverty, Socioeconomic Conditions, and Sexual Wellbeing

Sexual health includes positive aspects of sexuality and the possibility of having pleasurable sexual experiences. However, few researchers examine how socioeconomic conditions shape sexual wellbeing. This paper presents the concept of "erotic equity," which refers to how social and structural systems enable, or fail to enable, positive aspects of sexuality. In part one, we use this concept to consider potential pathways through which socioeconomic conditions, especially poverty, may shape sexuality. Part two builds from this theoretical framework to review the empirical literature that documents associations between socioeconomics and sexual wellbeing. This narrative review process located 47 studies from more than 22 countries. Forty-four studies indicated that individuals who reported more constrained socioeconomic conditions, primarily along the lines of income, education, and occupation, also reported poorer indicators of sexual wellbeing, especially satisfaction and overall functioning. Most studies used unidimensional measures of socioeconomic status, treating them as individual-level control variables; few documented socioeconomics as structural pathways through which erotic inequities may arise. Based on these limitations, in part three we make calls for the integration of socioeconomic conditions into sexuality researchers' paradigms of multi-level influences on sexuality.

Stress-induced arterial hypertension

Stress is considered as one of the factors associated with the development of many diseases, including the cardiovascular system. The history of studying stress as a risk factor for hypertension began in the first half of the 20th century and continued after the introduction of 24-hour blood pressure monitoring (ABPM) into clinical practice. Then it turned out that there is normotension, stable hypertension and latent hypertension: masked (when clinical BP is within the normal range, and arterial hypertension is recorded according to ABPM and/or self-monitoring of BP) and white coat hypertension (increased BP during a visit to the doctor when normal values of blood pressure according to ABPM or self-monitoring of BP). Currently, both variants of latent hypertension are classified as stress-induced arterial hypertension. Several models have been proposed for the study of stress, but two of them are more common in clinical studies: the Karasek model (based on an imbalance between job demands and job decision latitude) and the Siegrist model (based on an imbalance of effort and reward). There are only few studies in where attempts have been made to link the increase in BP with the parameters of stress response (for example, with hormonal levels) or genetic predisposition. The review discusses the most significant studies of stress-induced arterial hypertension published to date.

Low income and schizophrenia risk: a narrative review

Despite decades of research, the precise etiology of schizophrenia is not fully understood. Ample evidence indicates that the disorder derives from a complex interplay of genetic and environmental factors during vulnerable stages of brain maturation. Among the plethora of risk factors investigated, stress, pre- and perinatal insults, and cannabis use have been repeatedly highlighted as crucial environmental risk factors for schizophrenia. Compelling findings from population-based longitudinal studies suggest low income as an additional risk factor for future schizophrenia diagnosis, but underlying mechanisms remain unclear. In this narrative review, we 1) summarize the literature in support of a relationship between low (parental) income and schizophrenia risk, and 2) explore the mediating role of chronic stress, pre- and perinatal factors, and cannabis use as established risk factors for schizophrenia. Our review describes how low income facilitates the occurrence and severity of these established risk factors and thus contributes to schizophrenia liability. The broadest influence of low income was identified for stress, as low income was found to be associated with exposure to a multitude of severe psychological and physiological stressors. This narrative review adds to the growing literature reporting a close relationship between income and mental health.

Relationship Between Psychosocial Stress and Blood Pressure: The National Heart, Lung, and Blood Institute Family Heart Study

Introduction

Various domains of psychosocial stress have been significantly related to blood pressure. However, ambiguity is present in how these relationships are defined in the literature.

Objective

To add to the existing literature and examine the relationship between psychosocial stress (financial strain and job strain) and other cofactors on blood pressure.

Methods

This secondary analysis is designed to analyze the relationship between levels of job and financial stress and blood pressure outcomes among participants in the National Heart, Lung, and Blood Institute (NHLBI) Family Heart Study 2004-2008. The descriptive, cross-sectional design uses data from a subset of study participants, 350 White and 195 Black (n = 545), 338 female (62%), and all aged 18-56 years. Psychosocial stress was measured using the Singh Stress Scale. Resting systolic (SBP) and diastolic (DBP) blood pressure values obtained on a stress reactivity protocol day in the primary study, as well as calculated mean arterial pressure (MAP) were used for this analysis. Multivariate linear regression analyses were used to explore the relationship between psychosocial stress and blood pressure.

Results

In this young cohort, self-report of either financial strain or job strain was associated with lower blood pressure levels than those of participants who reported neither stressor. Differential sex and race effects appear to contribute to these results. Blood pressure levels were not significantly associated with self-report of both stressors.

Conclusion

Understanding the effects of various forms of stress on blood pressure may inform more precise HTN risk-factor screening and interventions to improve BP management.

Socio-demographic and psychosocial predictors of salivary cortisol from older male participants in the Speedwell prospective cohort study

INTRODUCTION

Associations between measures of socio-economic position and cortisol remain controversial. We examined the association between social class and cortisol reactivity in an aging male population.

METHODS

The Speedwell cohort study recruited 2348 men aged 45-59 years from primary care between 1979 and 1982 (phase I) where occupational social class was used to classify socioeconomic position. Men were seen on four more occasions, the last being between 1997 and 1999 (phase 5) when salivary samples were obtained capturing cortisol reactivity to stressors (cognitive test and venepuncture) and circadian variations (awakening and night-time cortisol levels, circadian slope and area under curve) at morning and afternoon clinic sessions. Longitudinal association between social class at phase 3 and log-transformed salivary cortisol measures at phase 5 was assessed using multivariable linear regression adjusted for variables associated with sampling time and age as a potential confounder, stratified by time of clinic session. We also explored possible mediation by psychosocial factors (e.g. work dislike) and health-related factors (e.g. waist-to-hip ratio and high-density lipoprotein cholesterol).

RESULTS

From 1768 living men, 1003 men (57%) attended a clinic at phase five, 854 participants (85% of attendees) returned home cortisol samples (mean age 71.7 years). We found little evidence of association between social class and baseline cortisol (i.e. prior to stress), cortisol response to stressors, and cortisol diurnal variation. However, we found lower social class was associated with higher and delayed post-stress recovery cortisol for participants that visited the clinic in the morning (adjusted β coefficient for manual versus non-manual 0.25 ng/ml; 95% CI: 0.06-0.48; P = 0.008). This association did not appear to be mediated by any of the measured psychosocial or health-related factors.

CONCLUSION

Our data did not show an overall association between social class and cortisol variability either diurnal or in response to a stressor. Lower social class was associated with a slower time to recover from exposure to stress in the morning, thereby increasing overall cortisol exposure. These findings provide some evidence for a mechanism that may contribute to the association between lower social class and a higher risk of adverse health outcomes.

Associations Between Financial Strain and Emotional Well-Being With Physiological Responses to Acute Mental Stress

OBJECTIVE

This study aimed to investigate associations between financial strain and emotional well-being, health, and physiological responses to acute mental stress.

METHODS

Participants were 542 healthy men and women aged 53 to 76 years from the Whitehall II study divided into those who reported no (n = 316), some (n = 135), or moderate/severe (n = 91) financial strain. Emotional well-being and self-reported health were assessed at baseline and 3 years later. Laboratory mental stress testing involved assessment of blood pressure (BP), heart rate, and lipid reactivity and recovery, and plasma interleukin 6 responses to challenging behavioral tasks. Analyses adjusted for objective financial status, age, sex, socioeconomic status (SES), and marital status.

RESULTS

Financial strain was positively associated with more depressive symptoms; lower positive affect; greater loneliness; lower optimism, self-esteem, and sense of control; and poorer self-reported physical health, mental health, and sleep (all, p < .001). Longitudinally, financial strain predicted poorer outcomes 3 years later, but associations were attenuated after baseline levels were taken into account. Financial strain was associated with reduced systolic and diastolic BP reactivity to acute stress (mean systolic BP increase = 32.34 [15.2], 28.95 [13.1], and 27.26 [15.2] mm Hg in the none, some, and moderate/severe financial strain groups), but not with heart rate, interleukin 6, or lipid responses.

CONCLUSIONS

Financial strain was correlated with a range of emotional and health-related outcomes independently of objective financial status. The diminished BP reactions to acute mental stress suggest that financial strain may contribute to dynamic chronic allostatic load.

Chronic Stress, Exercise and Cardiovascular Disease: Placing the Benefits and Risks of Physical Activity into Perspective

Chronic stress, which has been exacerbated worldwide by the lingering COVID pandemic, has been strongly linked to cardiovascular disease (CVD). In addition, autonomic dysregulation via sustained sympathetic activity has been shown to increase the risk of arrhythmias, platelet aggregation, acute coronary syndromes and heart failure. Fortunately, effective coping strategies have been shown to attenuate the magnitude of hyperarousal associated with the stress response, including moderate-to-vigorous lifestyle activity and/or structured exercise. A good-to-excellent level of cardiorespiratory fitness also appears to be highly cardioprotective. These beneficial effects have been substantiated by numerous studies that have evaluated the levels of stress reactivity and stress recovery in physically active individuals versus matched sedentary controls, as well as before and after exercise interventions. On the other hand, unaccustomed strenuous exercise in habitually sedentary persons with underlying CVD is associated with a disproportionate incidence of acute cardiac events. Moreover, extreme exercise regimens appear to increase coronary calcification and the likelihood of developing atrial fibrillation. This review summarizes these relations and more, with specific reference to placing the benefits and risks of physical activity into perspective.

The role of financial conditions for physical and mental health. Evidence from a longitudinal survey and insurance claims data

BACKGROUND

Both theory and empirical evidence suggest that financial conditions are influential for mental health and might contribute to physical health outcomes.

METHODS

Using longitudinal survey data and health insurance claims data from 1209 employees in a large U.S. health insurance company, we examined temporal associations between measures of financial safety, financial capability, financial distress, their summary index (financial security) and six subsequently measured mental and physical health outcomes.

RESULTS

We found that financial safety and financial capability were positively associated, while financial distress was negatively associated, with subsequent self-reported measures of physical and mental health, even after controlling for these health measures at baseline and other confounders. Additionally, financial conditions were associated with reduced risk of depression based on health insurance claims data. Financial safety was also associated with anxiety.

CONCLUSIONS

Policy-makers might consider the introduction of more effective measures for ensuring favorable financial conditions as an important contributor to better population health. Furthermore, policy could encourage teaching adequate financial management techniques and the importance of understanding of long-term consequences of financial decisions, as those might be pivotal for health outcomes.

Stressed-Out Oral Immunity: A Gateway From Socioeconomic Adversity to Periodontal Disease

OBJECTIVE

It has been suggested that adverse socioeconomic conditions "get under the skin" by eliciting a stress response that can trigger periodontal inflammation. We aimed to a) estimate the extent to which socioeconomic position (SEP) is associated with periodontal disease (PD) and proinflammatory oral immunity, and b) determine the contribution of psychosocial stress and stress hormones to these relationships.

METHODS

In this cross-sectional study (n = 102), participants (20-59 years old) completed financial and perceived stress questionnaires and underwent full-mouth periodontal examinations. SEP was characterized by annual household income and educational attainment. Cortisol, a biological correlate of chronic stress, was assessed in hair samples. Oral immunity was characterized by assessing oral inflammatory load and proinflammatory oral neutrophil function. Blockwise Poisson and logistic regression models were applied.

RESULTS

Compared with lower SEP, individuals in the middle- and higher-income categories had a significantly lower probability of PD (incidence rate ratio [IRR] = 0.5 [confidence interval {CI} = 0.3-0.7] and IRR = 0.4 [95% CI = 0.2-0.7]) and oral inflammatory load (IRR = 0.6 [95% CI = 0.3-0.8] and IRR = 0.5 [95% CI = 0.3-0.7]) and were less likely to have a proinflammatory oral immune function (odds ratio [OR] = 0.1 [95% CI = 0.0-0.7] and OR = 0.1 [95% CI = 0.0-0.9]). PD and oral immune parameters were significantly associated with financial stress and cortisol. Adjusting for financial stress and cortisol partially attenuated the socioeconomic differences in PD to IRR = 0.7 (95% CI = 0.5-0.8) and IRR = 0.6 (95% CI = 0.5-0.7) for the middle- and higher-income categories, respectively. Similar results were observed for proinflammatory immunity (OR = 0.2 [95% CI = 0.0-1.8] and OR = 0.3 [95% CI = 0.0-2.3]).

CONCLUSION

These findings suggest that psychosocial stress may contribute to a proinflammatory immunity that is implicated in PD pathobiology and provide insight into social-to-biological processes in oral health.

Predictors of Health Insurance, Life Insurance, and Retirement Savings Among NYC's Immigrant Taxi and For-Hire Vehicle Drivers

Taxi and for-hire vehicle (FHV) drivers are a predominantly immigrant population facing a range of occupational stressors, including lack of workplace benefits and increasing financial strain from tumultuous industry changes and now COVID-19's devastating impact. Bilingual research staff surveyed 422 New York City taxi/FHV drivers using a stratified sampling approach in driver-frequented locations to examine drivers' health and financial planning behaviors for the first time. Drivers lacked health insurance at double the NYC rate (20% vs. 10%). Life insurance and retirement savings rates were lower than U.S. averages (20% vs. 60%, 25% vs. 58%, respectively). Vehicle ownership was a significant predictor of health insurance, life insurance, and retirement savings. Compared to South Asian drivers, Sub-Saharan African drivers were significantly less likely to have health insurance and North African, and Middle Eastern drivers were significantly less likely to have retirement savings. Although most drivers indicated the importance of insurance and benefits, < 50% understood how to use them. Drivers felt primary care coverage to be most important followed by other health-related coverage, retirement benefits, and life insurance. Results reveal compelling addressable gaps in insurance and benefits coverage and the need to implement accessible financial literacy with navigation and advising services and programs.

Midlife improvements in financial situation are associated with a reduced dementia risk later in life: the CAIDE 30-year study

OBJECTIVES

Perceived financial strain is associated with various health conditions, but it is unknown whether it is associated with an increased risk for dementia. The goal is to examine the associations between midlife perceptions of financial situation and dementia risk later in life.

METHODS

Participants were derived from the Cardiovascular Risk Factors, Aging, and Dementia population-based cohort study (n = 2000) (between 1972 and 1987, baseline mean age 50 years) in Finland. Participants returned for two re-examinations in late life (in 1998 and 2005-2008, mean age 71 and 78 years). In this study, 1442 subjects that participated in at least one re-examination (mean total follow-up 25 years) were included in analyses. Financial strain was measured using two questions in midlife on perceptions of financial situation and perceptions of changes in financial situation. For each question, participants were categorized into three groups reporting improvement, worsening, or stability, with the latter set as the reference group. Analyses were adjusted for potential confounding factors.

RESULTS

The group reporting better financial situation had a reduced risk for dementia (fully adjusted model: odds ratio (OR): 0.53, 95% confidence interval (CI): 0.33-0.86). In contrast, the group reporting worse financial situation did not have an increased risk for dementia (OR: 1.04, 95% CI: 0.53-2.02). Analyses on perceptions of current financial situation showed that the groups reporting satisfaction or dissatisfaction with financial situation did not differ in risk for dementia.

CONCLUSION

This study is the first to show that midlife improvements in financial situation are associated with a reduced dementia risk later in life. Potential pathways related to stress reduction, improved lifestyle, and potential biological mechanisms are discussed.

Postural Control and Stress Exposure in Young Men: Changes in Cortisol Awakening Response and Blood Lactate

Background: It has recently been noticed that the quantity of stress affects postural stability in young women. The study was conducted with the goal of investigating whether increased stress may damagingly effect posture control in 90 young men (71 right-handed and 19 left-handed) while maintaining an upright bipedal posture, while keeping their eyes open or closed. Perceived Stress Scale (PSS) was administered and changes in free cortisol levels were monitored (Cortisol Awakening Response, CAR) in order to evaluate the amount of stress present during awakening, while the Profile of Mood States (POMS) was used to estimate distress on the whole. Posture control was evaluated with the use of a force platform, which, while computing a confidence ellipse area of 95%, was engaged by the Center of Pressure through five stability stations and was sustained for a minimum of 52 s, with and without visual input. Another goal of the experiment was to find out whether or not cortisol increases in CAR were linked with rises of blood lactate levels. Results: CAR, PSS and POMS were found to be extensively related. Furthermore, it has been observed that increases in salivary cortisol in CAR are associated with small but significant increases in blood lactate levels. As expected, stress levels did affect postural stability. Conclusions: The results of the present study confirm that the level of stress can influence postural stability, and that this influence is principally obvious when visual information is not used in postural control.

Can't leave it at home? The effects of personal stress on burnout and salesperson performance

Personal stress is a prevalent problem in a connected world. For salespeople, demands of a connected workplace have largely eliminated boundaries between personal and work life, allowing stress from personal issues to spill over into their work. Thus, problems of health, relationships, and finances are no longer "left at home" for salespeople. Rather, a less central workplace model (e.g., remote workplaces and mobile platforms) and 24/7 work expectations expand the workplace, which comingles personal and work demands. Utilizing a sample of 331 salespeople, we study personal stressors that cross boundaries into the workplace and find that they play a critical role in the formation of burnout across its dimensions, which leads to reduced salesperson performance. Our research contributes to the sales literature by investigating individual personal stressors via Job Demands and Conservation of Resources theories and offers insights for managers of salespeople that face both personal and work stress.

Childhood socioeconomic hardship, family conflict, and young adult hypertension: The Santiago Longitudinal Study

OBJECTIVE

Stress derived from socioeconomic disadvantage can be damaging to mental and physical health. This study uses longitudinal data on a large prospectively studied cohort to examine how socioeconomic hardship during childhood leads to hypertension in young adulthood by its effects on family conflict, anxiety-depression, and body mass.

METHOD

Data are from 1,039 participants of the Santiago Longitudinal Study who were studied in childhood (M age 10 years), adolescence (14-17 years), and young adulthood (21-26 years). As young adults, 26% had elevated blood pressure or hypertension.

RESULTS

Children from more economically disadvantaged families experienced higher levels of family conflict, which related to significant increases in anxiety-depression and body mass over time, both of which were directly linked to hypertension in young adulthood.

CONCLUSIONS

Findings provide an understanding of how early-life adversity associated with socioeconomic hardship manifests as stress-related health problems in adulthood. Intervention efforts that target overweight/obesity and anxiety and depression that stem from childhood poverty might be useful for reducing the socioeconomic disparities in adult health.

Who uses foodbanks and why? Exploring the impact of financial strain and adverse life events on food insecurity

Background

Rising use of foodbanks highlights food insecurity in the UK. Adverse life events (e.g. unemployment, benefit delays or sanctions) and financial strains are thought to be the drivers of foodbank use. This research aimed to explore who uses foodbanks, and factors associated with increased food insecurity.

Methods

We surveyed those seeking help from front line crisis providers from foodbanks (N = 270) and a comparison group from Advice Centres (ACs) (N = 245) in relation to demographics, adverse life events, financial strain and household food security.

Results

About 55.9% of foodbank users were women and the majority were in receipt of benefits (64.8%). Benefit delays (31.9%), changes (11.1%) and low income (19.6%) were the most common reasons given for referral. Compared to AC users, there were more foodbank users who were single men without children, unemployed, currently homeless, experiencing more financial strain and adverse life events (P = 0.001). Food insecurity was high in both populations, and more severe if they also reported financial strain and adverse life events.

Conclusions

Benefit-related problems appear to be a key reason for foodbank referral. By comparison with other disadvantaged groups, foodbank users experienced more financial strain, adverse life events, both increased the severity of food insecurity.

Risk factors for hypertension among young adults (18-35) years attending in Tenwek Mission Hospital, Bomet County, Kenya in 2018

Introduction

Hypertension ranks third in the world, after underweight and unsafe sex, in the list of six major risk factors contributing to the global disease. In Kenya, the prevalence stands at 24% in the general population, while among the young adults, the incidence of hypertension has been reported to be in the rise; a fact attributed to increased number of risks. We therefore sought to determine awareness and risk factors of hypertension among young adults attending Tenwek hospital.

Methods

A case-control study of young adults ages 18-35, involving 80 cases and 80 controls at Tenwek Mission Hospital, Bomet County. Cases included males and females newly diagnosed with hypertension (diagnosed at the time of data collection) and if they reported taking antihypertensive medication and reported as hypertensives in the hospital records at any clinic visit or at interview, while controls included persons with no history of hypertension.

Results

Those having a BMI≥25 were 3.05 times more likely to be hypertensive (OR: 3.05, 95% CI 1.26, 7.40; p=0.014). Having a relative suffering from hypertension increased almost thrice the odds of being hypertensive (OR: 2.78, 95% CI 1.20, 6. 46; p=0.018). Not drinking alcohol reduced the chance of suffering from hypertension by 70%, (OR=0.30, 95% CI 0.11, 0.81; p=0.017).

Conclusion

The prevalence of hypertension in younger adults is not as low as generally perceived. Preventive measures should be formulated in a manner to address variety of major risk factors in young adults.

Investigating associations between momentary stress and cortisol in daily life: What have we learned so far?

Since cortisol measurement in saliva has been established, it has been used as an indicator of stress-related hypothalamic-pituitary-adrenocortical axis activity. Concurrent development of methodological frameworks such as ambulatory assessment, ecological momentary assessment, and experience sampling have provided opportunities to combine both approaches in daily life research. The current review provides a summary of basic methodological principles and recommendations, as well as abstracts of findings of studies investigating momentary associations between stress and cortisol in daily life with an emphasis on within-subject associations (i.e. average covariance in repeated momentary assessments of stress and cortisol, and individual-specific deviations from the average covariance). Methodological challenges related to stress measurement, sampling principles, and appropriate statistical modeling are discussed, followed by a description of the historical development of studies on within-subject associations between momentary daily life stress and cortisol. The review concludes with a discussion of controversial methodological characteristics of these studies regarding operationalizations of stress, compliance, timing and frequency of stress and cortisol sampling, and reporting of effect sizes. Future research in this area would benefit from automated cortisol assessment, broadening of the scope of stress response measures, use of advanced statistical models that better account for dynamics in the stress process in daily life, and attempts to replicate findings. While previous studies of momentary stress and concurrent cortisol assessments have reliably confirmed some fundamental predictions from stress theory in daily life, future studies should aim at providing progress by testing innovative research questions and utilizing new technological developments.

Socioeconomic Status, Race/Ethnicity, and Diurnal Cortisol Trajectories in Middle-Aged and Older Adults

Objectives

Slow afternoon cortisol decline may be a marker of aging. We hypothesize that lower socioeconomic status (SES) and African American race are associated with lower waking cortisol and slower afternoon decline.

Method

Six salivary cortisol samples, collected within a 24-hr period from 566 cohort participants aged 56-78 years, were examined in random-effects models. SES measures included socioeconomic vulnerability (household income and assets <500% of poverty) and education (≥college, some college, and ≤high school). African Americans were compared with all others.

Results

Adjusting for age and sex, intermediate, but not low, education was associated with approximately 17% lower average waking cortisol and 1% slower decline, compared with high education. Socioeconomic vulnerability was not associated with waking cortisol or linear decline. Accounting for African American race/ethnicity, socioeconomic vulnerability was associated with a 3% faster decline, and education was not associated with cortisol. African Americans had 26% lower average waking cortisol and 1% slower decline than others.

Discussion

African American race/ethnicity, but not lower SES, was associated with lower waking cortisol and slower afternoon decline in middle-aged and older adults. This pattern is likely a marker of earlier biological aging in vulnerable groups. Race/ethnicity may compete with SES as a measure of cumulative vulnerability.

The Cortisol Awakening Response Mediates the Relationship Between Acculturative Stress and Self-Reported Health in Mexican Americans

BACKGROUND

The assessment of acculturative stress as synonymous with acculturation level overlooks the dynamic, interactive, and developmental nature of the acculturation process. An individual's unique perception and response to a range of stressors at each stage of the dynamic process of acculturation may be associated with stress-induced alterations in important biological response systems that mediate health outcomes. Evidence suggests the cortisol awakening response (CAR) is a promising pre-clinical biomarker of stress exposure that may link acculturative stress to self-reported health in Mexican Americans.

PURPOSE

The aim of the current study was to examine whether alterations in the CAR mediate the relationship between acculturative stress and self-reported health in Mexican Americans.

METHODS

Salivary cortisol samples were collected at awakening, 30, 45, and 60 min thereafter, on two consecutive weekdays from a sample of adult Mexican Americans. Acculturative stress and self-reported health were assessed. Data were aggregated and analyzed (n = 89) using a mixed effects regression model and path analysis.

RESULTS

Poorer self-reported health was associated with attenuated CAR profiles (primarily due to a diminished post-awakening rise in cortisol) predicted by both moderate and high levels of exposure to acculturative stress. Stress-induced alterations in the CAR mediated the relationship between exposure to acculturative stressors and self-reported health.

CONCLUSIONS

Findings demonstrate that different levels of acculturative stress are associated with distinct CAR profiles and suggest the CAR is one possible biological pathway through which exposure to culturally unique stressors may be linked to health disparities.

Long weekly working hours and ischaemic heart disease: a follow-up study among 145 861 randomly selected workers in Denmark

OBJECTIVES

The aim of the present study was to test if incidences of ischaemic heart disease (IHD) and usage of antihypertensive drugs are independent of weekly working hours (WWH) among full-time employees in Denmark.

DESIGN AND PARTICIPANTS

Data on WWH from participants of the Danish labour force surveys, 1999-2013, were linked on an individual level to national registers with data on socioeconomic status (SES), industry, emigrations, redeemed prescriptions, hospital contacts and deaths. Participants were followed until the end of 2014 (on average 7.7 years). Poisson regression was used to model incidence rates as a function of WWH. The analyses were controlled for calendar time, time passed since start of follow-up, employment in the healthcare industry, age, sex, SES and night work.

RESULTS

In total, we found 3635 cases of IHD and 20 648 cases of antihypertensive drug usage. The rate ratio of IHD was 0.95 (95% CI 0.85 to 1.06) for 41-48 compared with 32-40 WWH and 1.07 (0.94 to 1.21) for >48 compared with 32-40 WWH. The corresponding rate ratios for antihypertensive drug usage were 0.99 (0.95 to 1.04) and 1.02 (0.97 to 1.08). No statistically significant interactions between WWH and sex, SES and night work, respectively, were found.

CONCLUSION

In this Danish sample, we did not find any statistically significant association between WWH and IHD or antihypertensive drug usage.

Associations between psychological stress and smoking, drinking, obesity, and high blood pressure in an upper middle-income country in the African region

The direction and magnitude of the associations between cardiovascular risk factors (CVRFs) and psychological stress continue to be debated, and no data are available from surveys in the African region. In this study, we examine the associations between CVRFs and psychological stress in the Seychelles, a rapidly developing small island state in the African region. A survey was conducted in 1,240 adults aged 25-64 years representative of the Seychelles. Participants were asked to rank psychological stress that they had experienced during the past 12 months in four domains: work, social life, financial situation, and environment around home. CVRFs (high blood pressure, tobacco use, alcohol drinking, and obesity) were assessed using standard procedures. Psychological stress was associated with age, sex, and socioeconomic status. Overall, there were only few consistent associations between psychological stress and CVRFs, adjusting for age, sex, and socioeconomic status. Social stress was associated with smoking, drinking, and obesity, and there were marginal associations between stress at work and drinking, and between financial stress, and smoking and drinking. Psychological stress was not associated with high blood pressure. These findings suggest that psychological stress should be considered in cardiovascular disease prevention and control strategies.

Psychosocial functioning and the cortisol awakening response: Meta-analysis, P-curve analysis, and evaluation of the evidential value in existing studies

Cortisol levels rise immediately after awakening and peak approximately 30-45min thereafter. Psychosocial functioning influences this cortisol awakening response (CAR), but there is considerable heterogeneity in the literature. The current study used p-curve and meta-analysis on 709 findings from 212 studies to test the evidential value and estimate effect sizes of four sets of findings: those associating worse psychosocial functioning with higher or lower cortisol increase relative to the waking period (CARi) and to the output of the waking period (AUCw). All four sets of findings demonstrated evidential value. Psychosocial predictors explained 1%-3.6% of variance in CARi and AUCw responses. Based on these effect sizes, cross-sectional studies assessing CAR would need a minimum sample size of 617-783 to detect true effects with 80% power. Depression was linked to higher AUCw and posttraumatic stress to lower AUCw, whereas inconclusive results were obtained for predictor-specific effects on CARi. Suggestions for future CAR research are discussed.

Economic insecurity during the Great Recession and metabolic, inflammatory and liver function biomarkers: analysis of the UK Household Longitudinal Study

Background

Economic insecurity correlates with adverse health outcomes, but the biological pathways involved are not well understood. We examine how changes in economic insecurity relate to metabolic, inflammatory and liver function biomarkers.

Methods

Blood analyte data were taken from 6520 individuals (aged 25–59 years) participating in Understanding Society. Economic insecurity was measured using an indicator of subjective financial strain and by asking participants whether they had missed any bill, council tax, rent or mortgage payments in the past year. We investigated longitudinal changes in economic insecurity (remained secure, increase in economic insecurity, decrease in economic insecurity, remained insecure) and the accumulation of economic insecurity. Linear regression models were calculated for nine (logged) biomarker outcomes related to metabolic, inflammatory, liver and kidney function (as falsification tests), adjusting for potential confounders.

Results

Compared with those who remained economically stable, people who experienced consistent economic insecurity (using both measures) had worsened levels of high-density lipoprotein (HDL)-cholesterol, triglycerides, C reactive protein (CRP), fibrinogen and glycated haemoglobin. Increased economic insecurity was associated with adverse levels of HDL-cholesterol (0.955, 95% CI 0.929 to 0.982), triglycerides (1.077, 95% CI 1.018 to 1.139) and CRP (1.114, 95% CI 1.012 to 1.227), using the measure of financial strain. Results for the other measure were generally consistent, apart from the higher levels of gamma-glutamyl transferase observed among those experiencing persistent insecurity (1.200, 95% CI 1.110 to 1.297).

Conclusion

Economic insecurity is associated with adverse metabolic and inflammatory biomarkers (particularly HDL-cholesterol, triglycerides and CRP), heightening risk for a range of health conditions.

Support Buffers Financial Strain's Effect on Health-related Quality of Life

OBJECTIVES

Financial strain represents a perceived inability to meet financial needs and obligations and is associated with poorer health outcomes. Distinct facets of perceived social support may mitigate the deleterious effects of financial strain on health. In the present study, we examined the extent to which appraisal, belonging, and tangible social support ameliorate the effects of financial strain on health-related quality of life (HRQoL).

METHODS

A community sample (N = 238; 67.2% female; MAge = 43.4 years, SD = 13.1) completed inperson surveys as part of a larger study of health behaviors.

RESULTS

Greater financial strain and less social support were associated with poorer HRQoL. Additionally, both appraisal and belonging support moderated the effects of financial strain on some HRQoL components, such that higher appraisal and belonging support were associated with diminished effects of financial strain on HRQoL.

CONCLUSIONS

These findings suggest nuanced associations between financial strain and HRQoL. We discuss the implications for prevention and intervention programs.

Chronic Stress and C-Reactive Protein in Mothers During the First Postpartum Year

OBJECTIVE

Elevated levels of C-reactive protein (CRP) are associated with increased risk of cardiovascular and metabolic disease. The current study tested associations between psychosocial stress and CRP in a large sample of women during the first postpartum year.

METHODS

We analyzed data collected by the five-site Community Child Health Network study, which studied a predominately poor population. Participants (n = 1206 women; 54% African American, 23% white, 23% Hispanic/Latina) were recruited shortly after the birth of a child. Multiple linear regression analyses tested associations of psychosocial stress in several life domains (financial, neighborhood, family, coparenting, partner relationship, discrimination, and interpersonal violence) with log-transformed CRP concentrations at 6-month and 1-year postpartum.

RESULTS

Forty-eight percent of participants showed evidence of elevated CRP (≥3 mg/L) at 6-month postpartum, and 46% had elevated CRP at 12-month postpartum. Chronic financial stress at 1-month postpartum predicted higher levels of CRP at 6- (b = .15, SE = .05, p = .006) and 12-month postpartum (b = .15, SE = .06, p = .007) adjusting for race/ethnicity, income, education, parity, health behaviors, and chronic health conditions, though associations became nonsignificant when adjusted for body mass index.

CONCLUSIONS

In this low-income and ethnic/racially diverse sample of women, higher financial stress at 1-month postbirth predicted higher CRP. Study findings suggest that perceived financial stress stemming from socioeconomic disadvantage may be a particular deleterious form of stress affecting maternal biology during the year after the birth of a child.

The interaction between systemic inflammation and psychosocial stress in the association with cardiac troponin elevation: A new approach to risk assessment and disease prevention

We have previously shown that there is a complex and dynamic biological interaction between acute mental stress and acute release of inflammatory factors into the blood stream in relation to heart disease. We now hypothesize that the presence of chronic psychosocial stress may modify the weight of single test results for inflammation as a predictor of heart disease. Using a cross-sectional design, 500 participants free from heart disease drawn from the Whitehall II study in UK in 2006-2008 were tested for plasma fibrinogen as an inflammatory factor, financial strain as a marker of chronic psychosocial stress, coronary calcification measured using computed tomography, and for plasma high-sensitivity cardiac troponin T (HS-CTnT) as a marker of cardiac risk. Fibrinogen concentration levels above the average were associated with a 5-fold increase in the odds of HS-CTnT positivity only among individuals with financial strain (N=208, OR=4.73, 95%CI=1.67 to 13.40, P=0.003). Fibrinogen was in fact not associated with HS-CTnT positivity in people without financial strain despite the larger size of that subsample (n=292, OR=0.84, 95%CI=0.42 to 1.67, P=0.622). A test for interaction on the full sample (N=500) showed a P value of 0.010 after adjusting for a range of demographics, health behaviours, traditional cardiovascular risk factors, psychosocial stressors, inflammatory cytokines, and coronary calcification. In conclusion, elevated fibrinogen seems to be cardio-toxic only when is combined with financial strain. Chronic psychosocial stress may modify the meaning that we should give to single test results for inflammation. Further research is needed to confirm our results.

Stress and Subjective Age: Those With Greater Financial Stress Look Older

Subjective indicators of age add to our understanding of the aging process beyond the role of chronological age. We examined whether financial stress contributes to subjective age as rated by others and the self. The participants ( N = 228), aged 26-75, were from a Boston area satellite of the Midlife in the United States (MIDUS) longitudinal study. Participants reported how old they felt and how old they thought they looked, and observers assessed the participants' age based on photographs (other-look age), at two occasions, an average of 10 years apart. Financial stress was measured at Time 1. Controlling for income, general stress, health, and attractiveness, participants who reported higher levels of financial stress were perceived as older than their actual age to a greater extent and showed larger increases in other-look age over time. We consider the results on accelerated aging of appearance with regard to their implications for interpersonal interactions and in relation to health.

Working Time Arrangements as Potential Risk Factors for Ischemic Heart Disease Among Workers in Denmark: A Study Protocol

BACKGROUND

It has long been suspected that a worker's risk of developing an ischemic heart disease (IHD) may be influenced by his or her working time arrangements. A multitude of studies have been performed, and special attention has been given to long working hours and nighttime work. The statistical powers of the individual studies have, however, generally been too low to either dismiss or confirm an actual relationship, and meta-analyses of underpowered studies are generally associated with publication bias. Hence, uncertainty remains and whether these factors indeed are related to IHD has yet to be settled.

OBJECTIVE

This project will test whether the incidences of IHD and usage of antihypertensive drugs among employees in Denmark are independent of weekly working hours and nighttime work. The objective of this paper is to present the intended analyses.

METHODS

We will link individual participant data from the Danish labor force survey, 1999-2013, to data on socioeconomic status, industry, emigrations, redeemed prescriptions, hospitalizations, and deaths from registers covering the entire population of Denmark. The study will include approximately 160,000 participants, who will be followed through the registers, from the time of the interview until the end of 2014, for first occurrence of IHD and for antihypertensive drug treatment. We will use Poisson regression to analyze incidence rates as a function of nighttime work and of weekly working hours.

RESULTS

We expect results to be ready in mid-2017.

CONCLUSIONS

To our knowledge, this will be the largest study ever of its kind. It will, moreover, be free from hindsight bias, since the hypotheses, inclusion criteria, significance levels, and statistical models will be completely defined and published before we are allowed to link the exposure data to the outcome data.

Associations between hair cortisol concentration, income, income dynamics and status incongruity in healthy middle-aged women

A body of research demonstrates that financial disadvantage is associated with general health inequalities and higher mortality rates. Most studies make use of cross-sectional analyses, although income can also be viewed as a dynamic concept. The use of endocrine-markers as proxies for health can provide information about the pathways involved in these associations. Hair cortisol analysis has been developed as a method for assessing sustained cortisol output as it provides an estimate of cumulative cortisol secretion over a prolonged time. The present study assessed income and income trajectory over a 4-year period in 164 working women (aged 26-65) in relation to hair cortisol in a longitudinal design. A negative association between hair cortisol and concurrent income was found (p=0.025) and hair cortisol and changes in income over 4 years (p<0.001), after adjustment for age, BMI, smoking status, hair treatment and country. Status incongruity, a mismatch between educational status and income group, was related to higher cortisol levels compared with status congruity (p=0.009). These findings suggest that psychoneuroendocrinological pathways might partially explain the relationship between lower socio-economic status and adverse health outcomes. Future longitudinal research using hair cortisol analysis is warranted to clarify the time course of social mobility in relation to long-term cortisol, to investigate other underlying psychosocial factors implicated in these associations, and to determine the exact health implications of the neuroendocrine perturbations in individuals with limited economic resources.

Effects of Minority Status and Perceived Discrimination on Mental Health

Based in a minority social stress perspective, this study uses propensity score matching techniques to assess the impact of self-reported discrimination on mental health. Using a sample of 14,609 young adults from the National Longitudinal Study of Adolescent Health, we explore whether the effects of discrimination vary across sociodemographic characteristics (e.g. gender, race/ethnicity, sexual orientation, body mass), including both majority and minority populations. Further we investigate the heterogeneous effects of discrimination across propensity scores, or probabilities of experiencing discrimination. We find that self-reported discrimination increases the average perceived stress score and depressive symptoms score by roughly ½ standard deviation, but is not related to anxiety. Further, our results show that while all groups are negatively affected by discrimination, the magnitude of the impact is largest among groups with the lowest propensity scores.

Low stress resilience in late adolescence and risk of hypertension in adulthood

OBJECTIVE

Greater blood pressure reactivity to psychological stress has been associated with higher risk of developing hypertension. We hypothesised that low stress resilience based on psychological assessment early in life is associated with hypertension in adulthood.

METHODS

National cohort study of 1,547,182 military conscripts in Sweden during 1969-1997 (97-98% of all 18-year-old males) without prior history of hypertension, who underwent standardised psychological assessment by trained psychologists for stress resilience (1-9 scale), and were followed up for hypertension identified from outpatient and inpatient diagnoses during 1969-2012 (maximum age 62).

RESULTS

93,028 men were diagnosed with hypertension in 39.4 million person-years of follow-up. Adjusting for body mass index (BMI), family history and socioeconomic factors, low stress resilience at age 18 was associated with increased risk of hypertension in adulthood (lowest vs highest quintile: HR 1.43; 95% CI 1.40 to 1.46; p < 0.001; incidence rates, 278.7 vs 180.0 per 100,000 person-years), including a strong linear trend across the full range of stress resilience (p(trend) < 0.0001). We also found a positive additive interaction between stress resilience and BMI (p < 0.001), indicating that low stress resilience accounted for more hypertension cases among those with high BMI. Men with a combination of low stress resilience and high BMI had a more than threefold risk of hypertension.

CONCLUSIONS

These findings suggest that low stress resilience may contribute to etiological pathways for hypertension and accounts for more cases among those with high BMI. If confirmed, this knowledge may help inform better preventive interventions by addressing psychosocial risk factors and stress management across the lifespan.

The Effects of Job Instability and Financial Strain on C-Reactive Protein in a Sample of Mexican Immigrants

OBJECTIVE

Mexican immigrants have lower cardiovascular disease risk than US citizens, but risk increases with level of acculturation. Our study investigated whether job stress and financial strain would be related to inflammation (C-reactive protein), lipids, and blood pressure, and if they would play a role in the acculturation process in Mexican immigrants.

METHODS

A sample of 310 Mexican immigrants living in the United States were studied on measures of job stress, financial strain, acculturation, and cardiovascular disease risk factors (C-reactive protein, lipids, and blood pressure).

RESULTS

Job instability, financial strain, and acculturation, were related to inflammation, but psychological demands and decision latitude were not related. Lipids and blood pressure were not related to the variables of interest. Body mass index (BMI) was related to both increased acculturation and inflammation, and when controlling for BMI, acculturation was no longer a significant predictor of inflammation. Job instability and financial strain remained significant predictors of inflammation after controlling for BMI, sex, and age. Job instability and financial strain were not related to acculturation, suggesting that these factors are significant stressors for both newly arrived and more established immigrants.

CONCLUSIONS

Job instability and financial strain predict increased inflammation in Mexican immigrants but they do not play a role in the relationship between acculturation and C-reactive protein. The effects of acculturation on inflammation in this study were mediated by BMI.

Background Stress Inventory: Developing a Measure of Understudied Stress

Background stress is an understudied source of stress that involves both ambient stress and daily hassles upon which new stressors are superimposed. To date, an accurate measure of the background stress construct has not been available. We developed the Background Stress Inventory, a 25-item self-report measure that asks respondents to indicate how distressed they have felt over the past month and the majority of the past year across five domains: financial, occupation, environment, health and social. Seven hundred seventy-two participants completed the paper-and-pencil measure; the sample was randomly split into two separate subsamples for analyses. Exploratory factor analysis suggested five factors corresponding to these domains, and confirmatory factor analysis showed acceptable global fit (X(2)(255) = 456.47, comparative fit index = 0.94, root mean square error of approximation = 0.045). Cronbach's alpha (0.89) indicated good internal reliability. Construct validity analyses showed significant positive relationships with measures of perceived stressfulness (r = 0.62) and daily hassles (0.41), p's < 0.01. Depressive symptoms (0.62) and basal blood pressure (0.21) were both significantly associated with background stress, p's < 0.01. The importance of the proposed measure is reflected in the limited research base on the impact of background stress. Systematic investigation of this measure will provide insight into this understudied form of chronic stress and its potential influence on both psychological and physical endpoints.

Salivary Biomarkers of Chronic Psychosocial Stress and CVD Risks

Background:

The use of salivary biomarkers in stress research is increasing, and the precision and accuracy with which researchers are able to measure these biomarkers have dramatically improved. Chronic psychosocial stress is often linked to the pathogenesis of cardiovascular disease (CVD). Salivary biomarkers represent a noninvasive biological method of characterizing the stress phenomenon that may help to more fully describe the mechanism by which stress contributes to the pathogenesis and outcomes of CVD.

Objectives:

We conducted a systematic review of 40 research articles to identify the salivary biomarkers researchers have most commonly used to help describe the biological impact of chronic psychosocial stress and explore its associations with CVD risk. We address strengths and weaknesses of specimen collection and measurement.

Methods:

We used PubMed, CINAHL, EBSCO host, Web of Science, BIOSIS Previews, Biological Sciences (ProQuest), and Dissertations/Theses (ProQuest) to retrieve 387 initial articles. Once we applied our inclusion/exclusion criteria to specifically target adult human studies dealing with chronic stress rather than acute/laboratory-induced stress, 40 studies remained, which we synthesized using Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria.

Results:

Cortisol was the biomarker used most frequently. Sources of psychosocial stress included job strain, low socioeconomic status, and environmental factors. Overall, psychosocial stress was associated with CVD risks such as vascular pathology (hypertension, blood pressure fluctuation, and carotid artery plaque) as well as metabolic factors such as abnormal blood glucose, dyslipidemia, and elevated cardiac enzymes.

Conclusion:

Diverse salivary biomarkers have been useful in stress research, particularly when linked to CVD risks.

Economic pressure and health and weight management behaviors in African American couples: A family stress perspective

This study extends the family stress model by examining the influence of economic pressure on health and weight management behaviors mediated by depressive symptoms and spousal support among 506 African American married couples. The actor–partner interdependence model accounted for the interdependent nature of relationships. Findings support the family stress model; yet pathways differed slightly for husbands and wives. Economic pressure directly influenced depressive symptoms and spousal support. Spousal support was a buffer against poor health and weight management behaviors for husbands, while depressive symptoms exacerbated poor health and weight management behaviors for wives. These mechanisms have implications for practitioners who promote African American couples’ well-being.

Atypical secretion of cortisol in Nursing professionals

Objective To describe the frequency with which nursing staff in hospitals presents an altered diurnal pattern of cortisol secretion. Method These findings were based on results obtained from 56 randomly selected professional nursing staff working in outpatient clinics, medical clinics, surgical clinics, operating theaters, pediatric and adult emergency units, adult and pediatric intensive care units of a university hospital. The analysis of the diurnal cortisol pattern was based on saliva samples collected over two consecutive working days. Results 42.5% of these nursing staff members presented an atypical pattern of cortisol secretion. Furthermore, the longer the period of exercising this profession, the higher the cortisol concentration (r=0.346; p=0.020). Conclusion Over one-third of nursing staff samples displayed atypical cortisol secretion patterns. This suggests that these professionals are exposed, not only to a mental, but also to a biological, overload and thus, to a risk of contracting stress-related illnesses.

Stress exposure and postural control in young females

The aim of this study was to determine if heightened stress had an adverse affect on the postural control of 14 young right‑handed females during quiet standing in either the presence or the absence of visual input. The level of stress was evaluated by measuring the free cortisol response to awakening (cortisol awakening response; CAR) and by employing the perceived stress scale (PSS). Overall mood disturbance was measured using the profile of mood states (POMS). Postural control was evaluated using a force platform by measuring the 95% confidence ellipse area described by the center of pressure during 5 balance positions maintained for at least 52 sec, each with open and closed eyes. The results of this study revealed a significant positive correlation between CAR, PSS and POMS for each of the studied subjects. Furthermore, it was observed that whilst the level of stress was capable of influencing postural stability, this influence was particularly evident when no visual information was available. Additionally, it was determined that maintenance of posture is easier when the dominant foot is ahead, regardless of visual input.
