Women's heart health at mid-life: what is the role of psychosocial stress?

The Role of Psychosocial Stress on Cardiovascular Disease in Women: JACC State-of-the-Art Review

Psychosocial stress can affect cardiovascular health through multiple pathways. Certain stressors, such as socioeconomic disadvantage, childhood adversity, intimate partner violence, and caregiving stress, are especially common among women. The consequences of stress begin at a young age and persist throughout the life course. This is especially true for women, among whom the burden of negative psychosocial experiences tends to be larger in young age and midlife. Menarche, pregnancy, and menopause can further exacerbate stress in vulnerable women. Not only is psychosocial adversity prevalent in women, but it could have more pronounced consequences for cardiovascular risk among women than among men. These differential effects could reside in sex differences in responses to stress, combined with women's propensity toward vasomotor reactivity, microvascular dysfunction, and inflammation. The bulk of evidence suggests that targeting stress could be an important strategy for cardiovascular risk reduction in women.

Exercise to Prevent Accelerated Vascular Aging in People Living With HIV

Given advances in antiretroviral therapy, the mortality rate for HIV infection has dropped considerably over recent decades. However, people living with HIV (PLWH) experience longer life spans coupled with persistent immune activation despite viral suppression and potential toxicity from long-term antiretroviral therapy use. Consequently, PLWH face a cardiovascular disease (CVD) risk more than twice that of the general population, making it the leading cause of death among this group. Here, we briefly review the epidemiology of CVD in PLWH highlighting disparities at the intersections of sex and gender, age, race/ethnicity, and the contributions of social determinants of health and psychosocial stress to increased CVD risk among individuals with marginalized identities. We then overview the pathophysiology of HIV and discuss the primary factors implicated as contributors to CVD risk among PLWH on antiretroviral therapy. Subsequently, we highlight the functional evidence of premature vascular dysfunction as an early pathophysiological determinant of CVD risk among PLWH, discuss several mechanisms underlying premature vascular dysfunction in PLWH, and synthesize current research on the pathophysiological mechanisms underlying accelerated vascular aging in PLWH, focusing on immune activation, chronic inflammation, and oxidative stress. We consider understudied aspects such as HIV-related changes to the gut microbiome and psychosocial stress, which may serve as mechanisms through which exercise can abrogate accelerated vascular aging. Emphasizing the significance of exercise, we review various modalities and their impacts on vascular health, proposing a holistic approach to managing CVD risks in PLWH. The discussion extends to critical future study areas related to vascular aging, CVD, and the efficacy of exercise interventions, with a call for more inclusive research that considers the diversity of the PLWH population.

Daily social comparisons among women in midlife with elevated risk for cardiovascular disease: A within-person test of the identification/contrast model

Women age 40-60 are disproportionately affected by health problems that increase their risk for cardiovascular disease (CVD; e.g. hypertension). Social comparisons (i.e. self-evaluations relative to others) are known to influence health in this and other groups, but their nature and consequences in daily life are poorly understood. We conducted an ecological momentary assessment study over 10 days (5x/day) with 75 women ages 40-60 who had ≥1 CVD risk conditions (MAge = 51.6 years, MBMI = 34.0 kg/m2). Using a mix of frequentist and Bayesian analytic approaches, we examined characteristics of women's naturally occurring comparisons and tested predictions from the Identification/Contrast Model within-person (e.g. identifying with an upward target results in positive affect, whereas contrasting results in negative affect). Comparisons occurred at 21% of moments, with considerable within-person variability in response. In line with predictions from the Identification/Contrast Model, women were more likely to experience positive affect after upward identification or downward contrast and more likely to experience negative affect after upward contrast or downward identification, though observed nuances warrant additional consideration. Overall, findings support the Identification/Contrast Model to describe women's comparison experiences as they occur in daily life. Future work should determine pathways between the immediate consequences of comparisons and longer-term health outcomes.

Perceived Stress From Childhood to Adulthood and Cardiometabolic End Points in Young Adulthood: An 18-Year Prospective Study

BACKGROUND

We investigated how childhood-to-adulthood perceived stress patterns predict adult cardiometabolic risk.

METHODS AND RESULTS

This study included 276 participants from the Southern California Children's Health Study (2003-2014), and a follow-up assessment (2018-2021). Perceived stress (Perceived Stress Scale) was initially reported by participants' parents for themselves during early childhood (mean age, 6.3 years), and later self-reported during adolescence (13.3 years) and young adulthood (23.6 years). Participants were grouped into 4 stress patterns: consistently high, decreasing, increasing, and consistently low. Cardiometabolic risk was assessed in young adulthood by carotid artery intima-media thickness, systolic and diastolic blood pressure, obesity, percent body fat, android/gynoid ratio, and glycated hemoglobin. A cardiometabolic risk score was generated by summing the clinically abnormal markers. Multivariable linear and logistic regression models were used to (1) examine the associations between Perceived Stress Scale at 3 time points and adult cardiometabolic risk, and (2) assess the impact of stress pattern on adult cardiometabolic risk. Findings suggested that in adulthood, higher Perceived Stress Scale score was associated with increased overall cardiometabolic risk (β=0.12 [95% CI, 0.01-0.22]), carotid artery intima-media thickness (β=0.01 [95% CI, 0.0003-0.02]), systolic blood pressure (β=1.27 [95% CI, 0.09-2.45]), and diastolic blood pressure (β=0.94 [95% CI, 0.13-1.75]). Individuals with a consistently high adolescence-to-adulthood stress pattern had greater overall cardiometabolic risk (β=0.31 [95% CI, 0.02-0.60]), android/gynoid ratio (β=0.07 [95% CI, 0.02-0.13]), percent body fat (β=2.59 [95% CI, 0.01-5.17]), and greater odds of obesity (odds ratio, 5.57 [95% CI, 1.62-19.10]) in adulthood, compared with those with a consistently low Perceived Stress Scale score.

CONCLUSIONS

Consistently high perceived stress from adolescence to adulthood may contribute to greater cardiometabolic risk in young adulthood.

Psychological stress and the longitudinal progression of subclinical atherosclerosis

OBJECTIVE

In a midlife sample of adults, the present study tested the extent to which changes in psychological stress relate to the progression of subclinical cardiovascular disease over multiple years and explored the potential moderating role of cardiometabolic risk.

METHOD

Participants were screened to exclude those with clinical cardiovascular, respiratory, metabolic, and other chronic illnesses, as well as those taking psychotropic, cardiovascular, lipid, and glucose control medications. At baseline (N = 331) and then again at follow-up an average of 3 years later (N = 260), participants completed the 10-item Perceived Stress Scale, underwent assessments of their cardiometabolic risk, and underwent ultrasonography to measure carotid artery intima-media thickness (IMT), which is a surrogate indicator of subclinical atherosclerosis.

RESULTS

Regression models showed that the change in psychological stress from baseline to follow-up was positively associated with the corresponding change in IMT, with covariate control for age at baseline, sex at birth, and variability in length of follow-up across participants. Cardiometabolic risk factors did not statistically moderate this longitudinal association. In exploratory analyses, cardiometabolic risk factors also did not statistically mediate this association.

CONCLUSION

These longitudinal findings suggest that increases in psychological stress in midlife relate to corresponding increases in subclinical atherosclerosis. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Vascular function in hypertension: does gender dimension matter?

Blood pressure and vascular ageing trajectories differ between men and women. These differences develop due to sex-related factors, attributable to sex chromosomes or sex hormones, and due to gender-related factors, mainly related to different sociocultural behaviors. The present review summarizes the relevant facts regarding gender-related differences in vascular function in hypertension. Among sex-related factors, endogenous 17ß-estradiol plays a key role in protecting pre-menopausal women from vascular ageing. However, as vascular ageing (preceding and inducing hypertension) has a steeper increase in women than in men starting already from the third decade, it is likely that gender-related factors play a prominent role, especially in the young. Among gender-related factors, psychological stress (including that one related to gender-based violence and discrimination), depression, some psychological traits, but also low socioeconomic status, are more common in women than men, and their impact on vascular ageing is likely to be greater in women. Men, on the contrary, are more exposed to the vascular adverse consequences of alcohol consumption, as well as of social deprivation, while "toxic masculinity" traits may result in lower adherence to lifestyle and preventive strategies. Unhealthy diet habits are more prevalent in men and smoking is equally prevalent in the two sexes, but have a disproportional negative effect on women's vascular health. In conclusion, given the major and complex role of gender-related factors in driving vascular alterations and blood pressure patterns, gender dimension should be systematically integrated into future research on vascular function and hypertension and to tailor cardiovascular prevention strategies.

Relational and individual stress pathways linking discrimination and ageing cardiometabolic health

Perceived discrimination is a significant risk factor for worse ageing health outcomes. Yet, the specific individual and relational stress pathways linking discrimination to disease are less understood, especially in the context of cardiometabolic health. We tested family stress and psychophysiological distress (negative affect and high-risk lipid/fat metabolism) as mediators linking perceived discrimination to cardiometabolic morbidity and health appraisal over 20 years for midlife adults. Using data from participants who completed the Biomarker Project (2004-2009) of the Midlife in the U.S. project, and examining data over the study's three waves (1995-1996, 2004-2006, and 2013-2014), we used structural equation modelling to test pathways for participants who reported zero cardiometabolic conditions at baseline (n = 799). Greater Time 1 discrimination was associated with greater Time 2 family strain, which was in turn associated with worse negative affect; worse Time 2 negative affect was associated with worse Time 3 health appraisal; metabolic lipids risk did not serve as an indirect pathway to Time 3 cardiometabolic morbidity (χ²  = 147.74, p < 0.001; RMSEA = 0.056; CFI = 0.902; SRMR = 0.047). The inclusion of family in interventions to mitigate the impact of discrimination may be indicated for promoting cardiometabolic wellness.

Measurement of stress amongst working adults with cardiovascular disease

AIMS

Cardiovascular disease (CVD) is a leading cause of increased disability from work worldwide. Chronic stress including work-related stressors influences cardiovascular health. The purpose of this study was to assess stress levels amongst workers with CVD. The specific aims were to: (i) evaluate associations of the biological marker-hair cortisol concentration (HCC) with perceived stress and (ii) examine associations of HCC and perceived stress with sociodemographic factors and work-related factors.

METHODS AND RESULTS

This cross-sectional descriptive study (n = 75) of employed adults (≥ 21 age) with CVD assessed perceived stress, work-related factors including workplace support, job control, job strain, and work-life balance using valid and reliable instruments. Hair cortisol concentration was measured using collected hair samples. Data analyses included descriptive statistics, correlational, and ANOVA analysis. The sample was 64% female; 80% are White, 8% African American, 4% Asian, and 8% Hispanic; mean 12 years with CVD diagnosis. Hair cortisol concentration was significantly correlated with workplace support by co-workers (r = -0.328, P = 0.012), supervisors (r = -0.260, P = 0.05), and skill discretion (-0.297, r = 0.047) but not perceived stress. Those with better work-life balance had lower HCC (F = 3.077, P = 0.054) and lower perceived stress (F = 10.320, P < 0.01).

CONCLUSIONS

Although this sample of working adults with CVD reported high levels of perceived stress; only work-related factors were significantly associated with HCC. These results suggest that there are work-related stressors that cut across jobs and workplaces that may contribute to chronic stress in working adults. Healthcare providers across clinical and occupational settings have an important role in addressing work-related stress in working adults with CVD.

Psychosocial factors related to Cardiovascular Disease Risk in Young African American Women: a systematic review

OBJECTIVE

African American women are exposed to multiple adverse psychosocial factors, including racism, discrimination, poverty, neighborhood stress, anxiety, and depression. The impact of these psychosocial factors on cardiovascular disease (CVD) risk in women during early adulthood is limited. This review aims to summarize and synthesize the recent literature on psychosocial factors related to CVD risk in young African American women.

METHODS

We conducted a comprehensive search of the literature in PubMed, APA PsycINFO, and CINAHL. We systematically reviewed the literature for studies examining associations between psychosocial factors (e.g. racism, discrimination, neighborhood stress, anxiety) and CVD risk factors (e.g. body mass index [BMI], blood pressure, diabetes) in African American women age 19-24 years. Eligible studies measured at least one psychosocial factor, a CVD risk factor, and included young adult African American women (age 19-24) or reported sex-stratified analyses.

RESULTS

We identified nine studies that met our inclusion criteria: six cross-sectional and three longitudinal studies. Of these, eight studies reported that psychosocial factors (i.e. perceived stress, racial discrimination, internalized racism, depression) are related to higher BMI and blood pressure. The majority of studies were conducted among college students or had a small sample size (<200). The quality of six studies was rated as excellent; the remainder were good and fair.

CONCLUSIONS

Findings from this review suggest that exposure to adverse psychosocial factors may be related to increased CVD risk in early adulthood (age 19-24) in African American women. However, larger prospective analyses are necessary to examine these associations.

Role Stress and Sense of Control Predict Using Food to Cope With Stress in Midlife Women

Objective: The current study examined the association between role stress and using food to cope with stress in midlife women and examined sense of control as a potential underlying mechanism. Methods: An archival analysis was performed using data from 638 midlife women from the Midlife in the United States II study. Results: Hierarchical linear regression analyses demonstrated that work stress (β = .180, p < .001) and family stress (β = .138, p < .05) significantly predicted using food to cope with stress. Sense of control was a significant mediator between work stress and using food to cope with stress (b = 0.02, 95% CI [.0014, .0314]). Discussion: Midlife women with higher role stress related to work and family are more likely to use food to cope with stress, and sense of control seems to be the link between work stress and using food to cope.

Age- and sex-dependent changes of resting amygdalar activity in individuals free of clinical cardiovascular disease

PURPOSE

Amygdalar metabolic activity was shown to independently predict cardiovascular outcomes. However, little is known about age- and sex-dependent variability in neuronal stress responses among individuals free of cardiac disease. This study sought to assess age- and sex-specific differences of resting amygdalar metabolic activity in the absence of clinical cardiovascular disease.

METHODS

Amygdalar metabolic activity was assessed in 563 patients who underwent multimodality imaging by 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography and echocardiography for the evaluation of cardiac function.

RESULTS

After exclusion of 294 patients with structural or functional cardiovascular pathologies, 269 patients (128 women) remained in the final population. 18F-FDG amygdalar activity significantly decreased with age in men (r = - 0.278, P = 0.001), but not in women (r = 0.002, P = 0.983). Similarly, dichotomous analysis confirmed a lower amygdalar activity in men ≥ 50 years as compared to those < 50 years of age (0.79 ± 0.1 vs. 0.84 ± 0.1, P = 0.007), which was not observed in women (0.81 ± 0.1 vs. 0.82 ± 0.1, P = 0.549). Accordingly, a fully adjusted linear regression analysis identified age as an independent predictor of amygdalar activity only in men (B-coefficient - 0.278, P = 0.001).

CONCLUSION

Amygdalar activity decreases with age in men, but not in women. The use of amygdalar activity for cardiovascular risk stratification merits consideration of inherent age- and sex-dependent variability.

Social Role Stress, Reward, and the American Heart Association Life's Simple 7 in Midlife Women: The Study of Women's Health Across the Nation

Background Most women occupy multiple social roles during midlife. Perceived stress and rewards from these roles may influence health behaviors and risk factors. This study examined whether social role stress and reward were associated with the American Heart Association Life's Simple 7 in a cohort of midlife women in the United States. Methods and Results Women (n=2764) rated how stressful and rewarding they perceived their social roles during cohort follow-up (age range, 42-61 years). Body mass index, blood pressure, glucose, cholesterol, physical activity, diet, and smoking were assessed multiple times. All components were collected at the fifth study visit for 1694 women (mean age, 51 years). Adjusted linear and logistic regression models were used in analyses of the number of ideal components and the odds of achieving the ideal level of each component, respectively. Longitudinal analyses using all available data from follow-up visits were conducted. At the fifth visit, more stressful and less rewarding social roles were associated with fewer ideal cardiovascular factors. Higher average stress was associated with lower odds of any component of a healthy diet and an ideal blood pressure. Higher rewards were associated with greater odds of ideal physical activity and nonsmoking. Longitudinal analyses produced consistent results; moreover, there was a significant relationship between greater stress and lower odds of ideal glucose and body mass index. Conclusions Perceived stress and rewards from social roles may influence cardiovascular risk factors in midlife women. Considering social role qualities may be important for improving health behaviors and risk factors in midlife women.

The effect of lifestyle physical activity in reducing cardiovascular disease risk factors (blood pressure and cholesterol) in women: A systematic review

Cardiovascular diseases (CVD) are the most important cause of death in older women. Although there is strong evidence in the literature that moderate lifestyle physical activity (PA) is effective in modifiable CVD risk factors, there is limited evidence demonstrating which activities are effective in women. This systematic review was conducted to evaluate the effect of lifestyle PA interventions on CVD risk factors in women. Various databases were searched for English articles from 2000 to 2019. Eight articles met the selection criteria. It is recommended to use different combinations of interventions including moderate PA, to reduce CVD risk factors in women.

The Role of Emotional Regulation and Affective Balance on Health Perception in Cardiovascular Disease Patients According to Sex Differences

One of the challenges of aging is the increase of people with chronic diseases, such as cardiovascular disease (CVD). Men and women experience the disease differently. Therefore, it has an impact on how CVD is treated and its outcomes. This research analyzed the relationship between psychosocial variables and health promotion among cardiovascular patients, paying special attention to sex differences. A longitudinal study with cardiovascular patients (747 in phase 1 (122 women) and 586 in phase 2 (83 women)) was carried out. Participants were evaluated based on their sociodemographic characteristics, affective balance, regulatory negative affect self-efficacy, stress and anxiety regulation strategies, and perceived global health. Results showed that men presented significantly higher scores in positive affect, affective balance, and self-efficacy to regulate negative emotions, while women presented significantly higher scores in negative affect and the use of passive strategies to cope with stressful situations. Regression analyses showed that all psychological variables studied in phase 1 were significant predictors of health perception in phase 2. According to the results, it is necessary to include strategies to improve cardiovascular health through education and emotional regulation, with a gender focus.
