Socioeconomic status as a potential mediator of arterial aging in marginalized ethnic and racial groups: current understandings and future directions. J Appl Physiol (1985) 2024; 137:194-222. [PMID: 38813611 DOI: 10.1152/japplphysiol.00188.2024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2024] [Revised: 05/28/2024] [Accepted: 05/28/2024] [Indexed: 05/31/2024] Open
Abstract
Cardiovascular diseases (CVDs) are the leading cause of death in the United States. However, disparities in CVD-related morbidity and mortality exist as marginalized racial and ethnic groups are generally at higher risk for CVDs (Black Americans, Indigenous People, South and Southeast Asians, Native Hawaiians, and Pacific Islanders) and/or development of traditional CVD risk factors (groups above plus Hispanics/Latinos) relative to non-Hispanic Whites (NHW). In this comprehensive review, we outline emerging evidence suggesting these groups experience accelerated arterial dysfunction, including vascular endothelial dysfunction and large elastic artery stiffening, a nontraditional CVD risk factor that may predict risk of CVDs in these groups with advancing age. Adverse exposures to social determinants of health (SDOH), specifically lower socioeconomic status (SES), are exacerbated in most of these groups (except South Asians-higher SES) and may be a potential mediator of accelerated arterial aging. SES negatively influences the ability of marginalized racial and ethnic groups to meet aerobic exercise guidelines, the first-line strategy to improve arterial function, due to increased barriers, such as time and financial constraints, lack of motivation, facility access, and health education, to performing conventional aerobic exercise. Thus, identifying alternative interventions to conventional aerobic exercise that 1) overcome these common barriers and 2) target the biological mechanisms of aging to improve arterial function may be an effective, alternative method to aerobic exercise to ameliorate accelerated arterial aging and reduce CVD risk. Importantly, dedicated efforts are needed to assess these strategies in randomized-controlled clinical trials in these marginalized racial and ethnic groups.

A pilot cross-sectional investigation of chronic shame as a mediator of the relationship between subjective social status and self-rated health among middle-aged adults.

[PMID: 37842010 PMCID: PMC10569351 DOI: 10.1080/21642850.2023.2268697] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Accepted: 10/02/2023] [Indexed: 10/17/2023] Open
Abstract
Subjective social status (SSS) is an important independent predictor of health outcomes, however, the pathways through which it affects health are poorly understood. Chronic shame has previously been suggested as a potential mechanism but this has never been investigated and the relationship between chronic shame and health is under-researched. The purpose of this pilot study was to explore whether chronic shame explains a significant portion of the association between SSS and self rated health (SRH). Two-hundred American adults aged 30-55 years were recruited via a crowd-sourcing platform and were asked to provide information on their SSS, level of chronic shame, and SRH. Chronic shame significantly mediated the relationship between SSS and SRH. This pilot study provides initial evidence that shame explains a significant portion of the relationship between subjective social status and self-rated health. These findings support the initiation of larger, longitudinal investigations into chronic shame as a mediator of the subjective social status and self-rated health relationship.

Abstract
Gender plays a significant role in an individual's experiences and behaviors, as well as their expectations of others. Researchers have long operationalized gender using limited, mutually exclusive categories that fail to capture the rich variability within a gender-diverse population. While open-ended responses or multi-item scales may be a socially progressive approach and necessary for some gender-based research (e.g., Bauer et al., 2017), it may be unsuitable and statistically unfeasible for quantitative researchers in other areas. We analyzed responses from over 700 gender-diverse participants in the U.S. on a series of unipolar scales (i.e., gender identity, expression, and perception by others) that granted participants the flexibility of selecting a comprehensive self-definition while still enabling quantitative analysis of group differences as well as capturing maximum within-group variability. Using a cluster analysis, we found that participants' responses were best represented by five categories: Archetypical Men (n = 169), Archetypical Women (n = 168), Intertypical Men (n = 158), Intertypical Women (n = 126), and Nonconforming (n = 85). We explore the variability of characteristics and beliefs (e.g., gender norms, sexist beliefs) within and between traditional sex and these new gender categories. In this paper, we discuss theoretical considerations for future research and how using this comprehensive operationalization of gender can expand our understanding of "gender differences'' beyond the current scientific assumptions and barriers.

Abstract
Early theories of status dynamics in small groups portrayed intragroup status as a limited resource—as the status of one group member rises, the status of another must fall. Recent theorizing presents an alternative view: that the amount of status available to group members can be variable rather than fixed. Building on this view, we theorize that the average level of intragroup status changes as a function of group performance, such that the intragroup status of an average group member is higher in groups with higher performance and lower in groups with lower performance. We further theorize that changes in group solidarity partly account for the link between group performance and intragroup status. Across three preregistered studies, we find support for these hypotheses, which we hope will kindle interest in identifying other factors that can account for changes in intragroup status equilibria.

Abstract
OBJECTIVE Until effective treatments and vaccines are made readily and widely available, preventative behavioural health measures will be central to the SARS-CoV-2 public health response. While current recommendations are grounded in general infectious disease prevention practices, it is still not entirely understood which particular behaviours or exposures meaningfully affect one's own risk of incident SARS-CoV-2 infection. Our objective is to identify individual-level factors associated with one's personal risk of contracting SARS-CoV-2. DESIGN Prospective cohort study of adult participants from 26 March 2020 to 8 October 2020. SETTING The COVID-19 Citizen Science Study, an international, community and mobile-based study collecting daily, weekly and monthly surveys in a prospective and time-updated manner. PARTICIPANTS All adult participants over the age of 18 years were eligible for enrolment. PRIMARY OUTCOME MEASURE The primary outcome was incident SARS-CoV-2 infection confirmed via PCR or antigen testing. RESULTS 28 575 unique participants contributed 2 479 149 participant-days of data across 99 different countries. Of these participants without a history of SARS-CoV-2 infection at the time of enrolment, 112 developed an incident infection. Pooled logistic regression models showed that increased age was associated with lower risk (OR 0.98 per year, 95% CI 0.97 to 1.00, p=0.019), whereas increased number of non-household contacts (OR 1.10 per 10 contacts, 95% CI 1.01 to 1.20, p=0.024), attending events of at least 10 people (OR 1.26 per 10 events, 95% CI 1.07 to 1.50, p=0.007) and restaurant visits (OR 1.95 per 10 visits, 95% CI 1.42 to 2.68, p<0.001) were associated with significantly higher risk of incident SARS-CoV-2 infection. CONCLUSIONS Our study identified three modifiable health behaviours, namely the number of non-household contacts, attending large gatherings and restaurant visits, which may meaningfully influence individual-level risk of contracting SARS-CoV-2.

Abstract
Background Evidence suggests that subjective (perceived) social status (SSS) may predict health outcomes more strongly than objective social status, but little is known about the relationship between SSS and cardiovascular health (CVH). This study focuses on this relationship among diverse Hispanic/Latino adults because while poor CVH profiles are prevalent in this population, immigration complicates attempts to measure their social status. Methods and Results We analyzed baseline HCHS/SOL (Hispanic Community Health Study/Study of Latinos) data on 15 374 Hispanic/Latino adults aged 18 to 74 years in 2008 to 2011. SSS was assessed using the McArthur Scale, a 10‐rung “social ladder.” CVH was based on levels of 7 metrics defined by the American Heart Association. Linear and logistic regressions were used to examine cross‐sectional associations of SSS with CVH (overall and single metrics) after adjusting for objective social status, demographic, and health factors. Less than half of the population (46%) had Ideal scores in ≥4 metrics of CVH. In multivariable‐adjusted models, an increase in SSS was associated with a higher overall CVH score (β=0.04; 95% CI, 0.01–0.06) and greater likelihood of Ideal levels of body mass index, physical activity, and fasting blood glucose levels. Nativity and time in the United States modified the association between SSS and Ideal smoking. Conclusions Subjective measures of social status can enhance an understanding of CVH among Hispanic/Latino people. Future studies should explore the stability of SSS over time in comparison with objective social status and the mechanisms through which SSS may influence CVH.

Abstract
BACKGROUND Previous studies have shown that subjective social status (SSS) was positively associated with well-being in various populations. However, little is known about the relationship considering the underlying mechanism in patients with heart failure (HF). AIMS The aim was to study the effects of social connectedness and self-care confidence on the relationship between SSS and well-being in patients with HF according to the Reserve Capacity Model. METHODS AND RESULTS We recruited 296 patients from a general hospital using convenience sampling. SSS, social connectedness, self-care confidence, and well-being were assessed using self-reported questionnaires. A multiple mediation model was examined using the PROCESS macro in SPSS.Higher levels of SSS (r = 0.18, P < 0.01), social connectedness (r = 0.21, P < 0.01), and self-care confidence (r = 0.20, P < 0.01) were positively correlated with better emotional well-being, but not with physical well-being. The multiple mediation analysis revealed that the relationship between SSS and emotional well-being was mediated by social connectedness (effect: 0.061, 95% CI [0.014, 0.148]) and self-care confidence (effect: 0.110, 95% CI [0.006, 0.249]) separately, and together in serial (effect: 0.008, 95% CI [0.001, 0.028]). CONCLUSIONS Social connectedness and self-care confidence are multiple mediators of the relationship between SSS and emotional well-being. Interventions targeting to strengthening social connectedness and self-care confidence may improve emotional well-being directly. In addition, emotional well-being may be improved by enhancing SSS indirectly in patients with HF.

Abstract
Background In the absence of universal testing, effective therapies, or vaccines, identifying risk factors for viral infection, particularly readily modifiable exposures and behaviors, is required to identify effective strategies against viral infection and transmission. Methods We conducted a world-wide mobile application-based prospective cohort study available to English speaking adults with a smartphone. We collected self-reported characteristics, exposures, and behaviors, as well as smartphone-based geolocation data. Our main outcome was incident symptoms of viral infection, defined as fevers and chills plus one other symptom previously shown to occur with SARS-CoV-2 infection, determined by daily surveys. Findings Among 14, 335 participants residing in all 50 US states and 93 different countries followed for a median 21 days (IQR 10–26 days), 424 (3%) developed incident viral symptoms. In pooled multivariable logistic regression models, female biological sex (odds ratio [OR] 1.75, 95% CI 1.39–2.20, p<0.001), anemia (OR 1.45, 95% CI 1.16–1.81, p = 0.001), hypertension (OR 1.35, 95% CI 1.08–1.68, p = 0.007), cigarette smoking in the last 30 days (OR 1.86, 95% CI 1.35–2.55, p<0.001), any viral symptoms among household members 6–12 days prior (OR 2.06, 95% CI 1.67–2.55, p<0.001), and the maximum number of individuals the participant interacted with within 6 feet in the past 6–12 days (OR 1.15, 95% CI 1.06–1.25, p<0.001) were each associated with a higher risk of developing viral symptoms. Conversely, a higher subjective social status (OR 0.87, 95% CI 0.83–0.93, p<0.001), at least weekly exercise (OR 0.57, 95% CI 0.47–0.70, p<0.001), and sanitizing one’s phone (OR 0.79, 95% CI 0.63–0.99, p = 0.037) were each associated with a lower risk of developing viral symptoms. Interpretation While several immutable characteristics were associated with the risk of developing viral symptoms, multiple immediately modifiable exposures and habits that influence risk were also observed, potentially identifying readily accessible strategies to mitigate risk in the COVID-19 era.

Abstract
BACKGROUND Subjective social status (SSS) has shown inverse relationships with cardiometabolic risk, but intersectionalities of race/ethnicity and sex may indicate more nuanced relationships. PURPOSE To investigate associations of SSS with cardiometabolic risk markers by race/ethnicity and sex. METHODS Data were from Wave IV (2008) of the National Longitudinal Study of Adolescent to Adult Health (n = 4,847; 24-32 years), which collected biological cardiometabolic risk markers. A 10-step ladder captured SSS; respondents indicated on which step they perceived they stood in relation to other people in the U.S. higher values indicated higher SSS (range: 1-10). We tested the relationship between SSS and individual markers using generalized least square means linear regression models, testing three-way interactions between SSS, race/ethnicity, and sex (p < .10) before stratification. RESULTS SSS-race/ethnicity-sex interactions were significantly associated with waist circumference (p ≤ .0001), body mass index (BMI; p ≤ .0001), systolic blood pressure (SBP; p ≤ .0001), diastolic blood pressure (DBP; p = .0004), and high-density lipoprotein cholesterol (HDL-C; p = .07). SSS was associated with waist circumference (β [SE]: -1.2 (0.4), p < .05) and BMI (-0.6 [0.2], p < .01) for non-Hispanic White females, compared with males; with HDL-C among non-Hispanic White (0.2 [0.1]; p < .05) and Hispanic (0.3 (0.1); p < .05) females, compared with males; with SBP for non-Hispanic Asian (1.7 [0.8]; p < .05) and Multiracial (1.8 [0.8]; p < .05), versus White, females; and with DBP for non-Hispanic Black (0.8 [0.3]; p < .01), versus White, males. CONCLUSIONS SSS was differentially related to cardiometabolic risk markers by race/ethnicity and sex, suggesting intersectional aspects. Clinical and research applications of SSS should consider race/ethnicity- and sex-specific pathways influencing cardiometabolic risk.

Association between Urinary Phthalate Metabolites and Markers of Endothelial Dysfunction in Adolescents and Young Adults. TOXICS 2021; 9:toxics9020033. [PMID: 33562063 PMCID: PMC7915273 DOI: 10.3390/toxics9020033] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/16/2020] [Revised: 01/27/2021] [Accepted: 02/03/2021] [Indexed: 12/23/2022]
Abstract
Endothelial function is crucial in the pathogenesis of circulatory and cardiovascular toxicity; epidemiologic research investigating the association between phthalate exposure and endothelial dysfunction remains limited. We examined the associations between exposures to specific phthalates (di-2-ethylhexyl phthalate, DEHP; di-n-butyl phthalate, DnBP) and circulating endothelial and platelet microparticles (EMPs and PMPs) in adolescents and young adults. Of the 697 participants recruited, anthropometric measurements and health-related behaviors relevant to cardiovascular risks were collected and assessed. Urine and serum were collected and analyzed with liquid chromatography-tandem mass spectrometry (LC-MS/MS) and flow cytometry. Multiple linear regression indicated that increases in urinary concentrations of ΣDEHP and MnBP (mono-n-butyl phthalate), across quartiles, were positively associated with serum EMPs level (p for trend <0.001 and <0.001; β = 0.798 and 0.007; standard error = 0.189 and 0.001, respectively). Moreover, female and overweight subjects had higher MnBP, and males were more vulnerable to DnBP exposure compared to females. In conclusion, our results demonstrate a dose-response relationship between exposures to phthalates (ΣDEHP and MnBP) and microparticle formation (EMPs and PMPs) in adolescents and young adults. The findings indicate that exposures to phthalates of both low and high-molecular weight are positively associated with microparticle production, and might contribute to endothelial dysfunction; such damage might manifest in the form of atherosclerotic-related vascular diseases. Future in vivo and in vitro studies are warranted to elucidate whether a causal relationship exists between phthalate exposure and EMPs and PMPs.

Abstract
Psychological stress induces different alterations in the organism in order to maintain homeostasis, including changes in hematopoiesis and hemostasis. In particular, stress-induced hyper activation of the autonomic nervous system and hypothalamic–pituitary–adrenal axis can trigger cellular and molecular alterations in platelets, coagulation factors, endothelial function, redox balance, and sterile inflammatory response. For this reason, mental stress is reported to enhance the risk of cardiovascular disease (CVD). However, contrasting results are often found in the literature considering differences in the response to acute or chronic stress and the health condition of the population analyzed. Since thrombosis is the most common underlying pathology of CVDs, the comprehension of the mechanisms at the basis of the association between stress and this pathology is highly valuable. The aim of this work is to give a comprehensive review of the studies focused on the role of acute and chronic stress in both healthy individuals and CVD patients, focusing on the cellular and molecular mechanisms underlying the relationship between stress and thrombosis.

Abstract
BACKGROUND Potential routes whereby systemic inflammation, oxidative stress and mitochondrial dysfunction may drive the development of endothelial dysfunction and atherosclerosis, even in an environment of low cholesterol, are examined. MAIN TEXT Key molecular players involved in the regulation of endothelial cell function are described, including PECAM-1, VE-cadherin, VEGFRs, SFK, Rho GEF TRIO, RAC-1, ITAM, SHP-2, MAPK/ERK, STAT-3, NF-κB, PI3K/AKT, eNOS, nitric oxide, miRNAs, KLF-4 and KLF-2. The key roles of platelet activation, xanthene oxidase and myeloperoxidase in the genesis of endothelial cell dysfunction and activation are detailed. The following roles of circulating reactive oxygen species (ROS), reactive nitrogen species and pro-inflammatory cytokines in the development of endothelial cell dysfunction are then described: paracrine signalling by circulating hydrogen peroxide, inhibition of eNOS and increased levels of mitochondrial ROS, including compromised mitochondrial dynamics, loss of calcium ion homeostasis and inactivation of SIRT-1-mediated signalling pathways. Next, loss of cellular redox homeostasis is considered, including further aspects of the roles of hydrogen peroxide signalling, the pathological consequences of elevated NF-κB, compromised S-nitrosylation and the development of hypernitrosylation and increased transcription of atherogenic miRNAs. These molecular aspects are then applied to neuroprogressive disorders by considering the following potential generators of endothelial dysfunction and activation in major depressive disorder, bipolar disorder and schizophrenia: NF-κB; platelet activation; atherogenic miRs; myeloperoxidase; xanthene oxidase and uric acid; and inflammation, oxidative stress, nitrosative stress and mitochondrial dysfunction. CONCLUSIONS Finally, on the basis of the above molecular mechanisms, details are given of potential treatment options for mitigating endothelial cell dysfunction and activation in neuroprogressive disorders.

Abstract
The links between low socioeconomic status and poor health are well established, yet despite adversity, some individuals with low socioeconomic status appear to avoid these negative consequences through adaptive coping. Previous research found a set of strategies, called shift-and-persist (shifting the self to stressors while persisting by finding meaning), to be particularly adaptive for individuals with low socioeconomic status, who typically face more uncontrollable stressors. This study tested (a) whether perceived social status, similar to objective socioeconomic status, would moderate the link between shift-and-persist and health, and (b) whether a specific uncontrollable stressor, unfair treatment, would similarly moderate the health correlates of shift-and-persist. A sample of 308 youth (Meanage = 13.0, range 8-17), physician diagnosed with asthma, completed measures of shift-and-persist, unfair treatment, asthma control, and quality of life in the lab, and 2 weeks of daily diaries about their asthma symptoms. Parents reported on perceived family social status. Results indicated that shift-and-persist was associated with better asthma profiles, only among youth from families with lower (vs. higher) parent-reported perceived social status. Shift-and-persist was also associated with better asthma profiles, only among youth who experienced more (vs. less) unfair treatment. These findings suggest that the adaptive values of coping strategies for youth with asthma depend on the family's perceived social status and on the stressor experienced.

Abstract
Background Perception of low subjective social status (SSS) relative to others in society or in the community has been associated with increased risk of cardiovascular disease. Our objectives were to determine whether low SSS in society was associated with barriers to access to care or hospital readmission in patients with established cardiovascular disease, and whether perceptions of discordantly high SSS in the community modified this association. Methods We conducted a prospective cohort study from 2009 to 2013 in Canada, United States, and Switzerland in patients admitted to hospital with acute coronary syndrome (ACS). Data on access to care and SSS variables were obtained at baseline. Readmission data were obtained 12 months post-discharge. We conducted multivariable logistic regression to model the odds of access to care and readmission outcomes in those with low versus high societal SSS. Results One thousand ninety patients admitted with ACS provided both societal and community SSS rankings. The low societal SSS cohort had greater odds of reporting that their health was affected by lack of health care access (OR 1.48, 95% CI 1.11, 1.97) and of experiencing cardiac readmissions (1.88, 95% CI 1.15, 3.06). Within the low societal SSS cohort, there was a trend toward fewer access to care barriers for those with discordantly high community SSS though findings varied based on the outcome variable. There were no statistically significant differences in readmissions based on community SSS rankings. Conclusion Low societal SSS is associated with increased barriers to access to care and cardiac readmissions. Though attenuated, these trends remained even when adjusting for clinical and sociodemographic factors, suggesting that perceived low societal SSS has health effects above and beyond objective socioeconomic factors. Furthermore, high community SSS may potentially mitigate the risk of experiencing barriers to access to health care in those with low societal SSS, though these associations were not statistically significant. Subjective social status relative to society versus relative to the community seem to represent distinct concepts. Insight into the differences between these two SSS constructs is imperative in the understanding of cardiovascular health and future development of public health policies.

Abstract
OBJECTIVE Both social stratification (e.g., social rank) as well as economic resources (e.g., income) are thought to contribute to socioeconomic health disparities. It has been proposed that subjective socioeconomic status (an individual's perception of his or her hierarchical rank) provides increased predictive utility for physical health over and above more traditional, well-researched socioeconomic constructs such as education, occupation, and income. METHOD PsycINFO and PubMed databases were systematically searched for studies examining the association of subjective socioeconomic status (SES) and physical health adjusting for at least 1 measure of objective SES. The final sample included 31 studies and 99 unique effects. Meta-analyses were performed to: (a) estimate the overlap among subjective and objective indicators of SES and (b) estimate the cumulative association of subjective SES with physical health adjusting for objective SES. Potential moderators such as race and type of health indicator assessed (global self-reports vs. more specific and biologically based indicators) were also examined. RESULTS Across samples, subjective SES shows moderate overlap with objective indicators of SES, but associations are much stronger in Whites than Blacks. Subjective SES evidenced a unique cumulative association with physical health in adults, above and beyond traditional objective indicators of SES (Z = .07, SE = .01, p < .05). This association was stronger for self-rated health than for biologically based and symptom-specific measures of health. Almost all available data were cross-sectional and do not allow for strong causal inference. CONCLUSIONS Subjective SES may provide unique information relevant to understanding disparities in health, especially self-rated health. (PsycINFO Database Record

Abstract
BACKGROUND AND AIMS The development of adolescence psychological health over a 3-year period and its relationship to peripheral endothelial function and the hypothalamic-pituitary-adrenal (HPA)-axis activity were examined in a cohort of healthy adolescents in a longitudinal study. METHODS A total of 162 adolescents (94 females) participated in both baseline (mean age 14.5 ± 1 years) and three-year follow-up studies. Psychological health was evaluated by self-report using the Beck Youth Inventories of Emotional and Social Impairment and the psychosomatic problem scale. Peripheral endothelial function was assessed using a peripheral artery tonometry device. The HPA-axis activity measured as cortisol awakening response (CAR) was assessed only at follow-up by collecting two saliva samples, immediately after awakening and 15 min later. Physical activity, smoking and parental education were assessed by questionnaires. RESULTS Adolescents reported increased depression and decreased anger over three years, while only females reported increased psychosomatic complaints. Reduced peripheral endothelial function was associated with high level of anger (β = -0.332, p = 0.018) and disruptive behaviour (β = -0.390, p = 0.006) over three years in males, but not in females, after adjusting for covariates. Blunted cortisol awakening response was associated with high level of anxiety (β = -0.235, p = 0.017), depression (β = -0.203, p = 0.038), anger (β = -0.185, p = 0.048), and low level of self-concept (β = 0.289, p = 0.002) after adjusting for covariates. CONCLUSIONS High level of negative emotions during adolescence may have adverse effects on peripheral endothelial function and the regulation of the HPA-axis activity, while high level of self-concept might be protective.

Abstract
OBJECTIVE To determine the association between subjective social status (SSS), or the individual's perception of his or her position in the social hierarchy, and the odds of coronary artery disease (CAD), hypertension, diabetes, obesity and dyslipidaemia. STUDY DESIGN Systematic review and meta-analysis. METHODS We searched PubMed, MEDLINE, EMBASE, CINAHL, PsycINFO, SocINDEX, Web of Science and reference lists of all included studies up to October 2014, with a verification search in July 2015. Inclusion criteria were original studies in adults that reported odds, risk or hazard ratios of at least one outcome of interest (CAD, hypertension, diabetes, obesity or dyslipidaemia), comparing 'lower' versus 'higher' SSS groups, where SSS is measured on a self-anchoring ladder. ORs were pooled using a random-effects model. RESULTS 10 studies were included in the systematic review; 9 of these were included in the meta-analysis. In analyses unadjusted for objective socioeconomic status (SES) measures such as income, education or occupation, the pooled OR comparing the bottom versus the top of the SSS ladder was 1.82 (95% CI 1.10 to 2.99) for CAD, 1.88 (95% CI 1.27 to 2.79) for hypertension, 1.90 (95% CI 1.25 to 2.87) for diabetes, 3.68 (95% CI 2.03 to 6.64) for dyslipidaemia and 1.57 (95% CI 0.95 to 2.59) for obesity. These associations were attenuated when adjusting for objective SES measures, with the only statistically significant association remaining for dyslipidaemia (OR 2.10, 95% CI 1.09 to 4.06), though all ORs remained greater than 1. CONCLUSIONS Lower SSS is associated with significantly increased odds of CAD, hypertension, diabetes and dyslipidaemia, with a trend towards increased odds of obesity. These trends are consistently present, though the effects attenuated when adjusting for SES, suggesting that perception of one's own status on a social hierarchy has health effects above and beyond one's actual income, occupation and education.

Abstract
OBJECTIVE To investigate associations of work hours, job control, job demands, job strain, and occupational category with brachial artery flow-mediated dilation (FMD) in 1499 Multi-Ethnic Study of Atherosclerosis participants. METHODS Flow-mediated dilation was obtained using high-resolution ultrasound. Mean values of FMD were examined across categories of occupation, work hours, and the other exposures using regression analyses. RESULTS Occupational category was significantly associated with FMD overall, with blue-collar workers showing the lowest mean values-management/professional = 4.97 ± 0.22%; sales/office = 5.19 ± 0.28%; services = 4.73 ± 0.29%; and blue-collar workers = 4.01 ± 0.26% (adjusted P < 0.001). There was evidence of effect modification by sex (interaction P = 0.031)-significant associations were observed among women (adjusted P = 0.002) and nearly significant results among men (adjusted P = 0.087). Other exposures were not significantly associated with FMD. CONCLUSIONS Differences in endothelial function may account for some of the variation in cardiovascular disease across occupational groups.

Abstract
Subjective social status (SSS), or one's perceived social standing, is linked robustly to mental and physical health and is thought to be determined in part by a cognitive average of one's past, present and expected socioeconomic status. However, this averaging principle awaits a formal test. Further, cultures differ with regard to how they perceive and discount time. In this study, I draw upon cross-sectional data from the United States and Japan (2005 MIDUS non-Hispanic whites and 2008 MIDJA), which measured subjective status in terms of one's perceived standing within a personally defined community. I compare equal and unequal cognitive averaging models for their goodness of fit relative to a traditional present-based model. Socioeconomic status is assessed broadly, in terms of past, present and expected overall work and financial situations. In the United States, averaging models do not fit the data consistently better than a present-based model of SSS. However, in Japan, averaging models do fit SSS consistently better. These fit conclusions are robust to controlling for negative affect.

Abstract
PURPOSE OF REVIEW Subjective social status (SSS) predicts health outcomes above and beyond traditional objective measures of social status, such as education, income and occupation. This review summarizes and integrates recent findings on SSS and health. RECENT FINDINGS Current studies corroborate associations between low SSS and poor health indicators by extending previous findings to further populations and biological risk factors, providing meta-analytic evidence for adolescents and by demonstrating that negative affect may not confound associations between SSS and self-rated health. Recent findings also highlight the relevance of SSS changes (e.g. SSS loss in immigrants) and the need to consider cultural/ethnical differences in psychological mediators and associations between SSS and health. SUMMARY SSS is a comprehensive measure of one's social position that is related to several poor health outcomes and risk factors for disease. Future investigation, particularly prospective studies, should extend research on SSS and health to further countries/ethnic groups, also considering additional psychological and biological mediators and dynamic aspects of SSS. Recently developed experimental approaches to manipulate SSS may also be promising.

Abstract
OBJECTIVE Living in adverse neighborhood conditions has been linked with greater prevalence of cardiovascular disease (CVD). We aimed to learn whether perceived neighborhood problems are related to attenuated nocturnal blood pressure (BP) dipping, a risk factor for CVD morbidity. METHOD A sample of 133 adults (71 male, 62 female; 80 White, 53 Black) underwent 24-hr ambulatory blood pressure monitoring. The neighborhood problem scale (NPS) was used to assess neighborhood environmental stressors. RESULTS Nocturnal dipping in systolic (SBP), diastolic (DBP) and mean arterial (MAP) blood pressure was reduced in individuals with higher NPS scores (p < .05). Hierarchical regression analyses revealed that neighborhood problems explained 4%-6% of the variance in SBP, DBP, and MAP dipping (p < .05) even after adjusting for several theoretical confounders such as social status, age, gender, race, body mass index (BMI), smoking, exercise, depression and discrimination. CONCLUSION Neighborhood problems may contribute to attenuated BP dipping beyond the effect of known risk factors.

Abstract
This study investigated the effect of self-reported racial discrimination on endothelial responses to acute laboratory mental stress among post-menopausal women. One-hundred thirteen women (n = 94 self-identified as White and n = 19 self-identified as racial/ethnic minority), 43% with type 2 diabetes, reported lifetime experiences of racial/ethnic discrimination. Repeated assessments of flow-mediated dilation were performed at baseline, immediately after 5 min of mental arithmetic and at 20-min recovery. Both White and racial/ethnic minority women reported lifetime discrimination, with rates significantly higher among minorities. Self-reported lifetime discrimination was associated with attenuated flow-mediated dilation at recovery. Confounding variables, including clinical characteristics, mood, personality traits, other life stressors and general distress, did not better account for the effect of racial discrimination. Neither race/ethnicity nor diabetes status moderated the effect. The perceived stressfulness of the mental arithmetic was not associated with the endothelial response. In conclusion, self-reported lifetime discrimination is associated with attenuated endothelial recovery from acute mental stress. Elucidating the effects of discrimination and the biological mechanisms through which it affects the vasculature may suggest interventions to improve health.

African American (AA) women are nearly twice as likely as non-Hispanic White (NHW) women to develop atherosclerosis associated with cardiovascular disease. Compelling evidence demonstrates that stress-related biomarkers, such as heat shock protein-70 (HSP70), are associated with increased atherosclerosis risk. Yet little is known about how social factors such as perceived discrimination, subjective social status, and socioeconomic status contribute to the levels of these biomarkers in women with atherosclerosis. The aims of this pilot study were to (1) describe perceived everyday discrimination, subjective social status, perceived stress, and HSP70 level in AA and NHW women diagnosed with coronary or carotid artery disease requiring intervention and (2) determine the extent to which perceived discrimination, subjective social status, and perceived stress are associated with HSP70 level, controlling for age, education, and race. The sample for this cross-sectional, descriptive pilot study consisted of 10 AA and 21 NHW women admitted to the hospital for elective percutaneous cardiac intervention or carotid endarterectomy. Participants completed questionnaires measuring psychosocial variables and provided blood samples for analysis of HSP70. Race, age, education, perceived stress, perceived discrimination, and subjective social status significantly (p = .022) explained 34% of the variance in HSP70 levels. However, only subjective social status (p = .031) and AA race (p = .031) were significant independent predictors of HSP70 levels, with lower subjective social status and AA race associated with higher HSP70. Although larger studies are needed to confirm these results, findings imply that race and subjective social status may play an important role in predicting stress biomarker levels.

Abstract
As part of a prospective cohort study of 1354 female and 347 male healthcare personnel, we examined the stability of subjective social status over ~7 months and the prospective association between subjective social status and self-rated health status. Most (82%) subjective social status ratings were stable (within ±1 point). Lower baseline subjective social status among healthcare personnel was associated with more subsequent reports of fatigue and headache and worsening global self-rated health status. Healthcare personnel who placed themselves on the bottom half of the subjective social status ladder were four times more likely to experience a decline in global self-rated health status and half as likely to improve to excellent self-rated health status.

Abstract
OBJECTIVE Several poor health outcomes, including cardiovascular risk, have been associated with both subjective social status (SSS) and sympathetic overactivity. Because prolonged sympathetic overactivation down regulates beta adrenergic receptor (β-AR) function, reduced β-AR responsiveness is considered an indicator of sympathetic overactivity and a cardiovascular risk factor. Though prior research has focused on objective social status and β-AR function, no studies have examined the association between SSS and β-AR function. We aimed to learn whether SSS predicts the in vivo responsiveness of β-ARs. METHODS We assessed the chronotropic 25 dose (CD25), an in vivo marker of β-AR responsiveness, in 94 healthy participants. The MacArthur scales of subjective social status were used to assess SSS in the U.S.A. (SSS-USA) and in the local community (SSS-C). Objective social status was analyzed by calculating the Hollingshead two-factor index. RESULTS β-AR responsiveness was reduced (as indicated by higher CD25 values) in participants with lower SSS-USA (p = .007) and lower SSS-C (p < .001). The relationship between CD25 and SSS was particularly robust with respect to SSS-C. Hierarchical regression analyses revealed that SSS-C remained a significant predictor of CD25 (p < .001) and accounted for 14% of the total variance (32%) in CD25 after adjusting for sociodemographic variables (age, ethnicity, gender), health factors (exercise, smoking status, body mass index) and objective social status. CONCLUSION Our results indicate that β-AR function may be an important component of the link between SSS and health.

Abstract
Mental stress is an important factor contributing to recognized mechanisms underlying cardiovascular events. Among these, stress-related endothelial dysfunction is an early risk factor that predicts future development of severe cardiovascular disorders. Acute mental stress by a variety of tests impairs endothelial function in humans, although the opposite results have been reported by some investigators. Chronic stress always deteriorates endothelial function in humans and experimental animals. Stress hormones, such as glucocorticoids and pro-inflammatory cytokines, and endothelin-1 liberated in response to mental stress participate in endothelial dysfunction possibly via downregulation of endothelial nitric oxide synthase (eNOS) expression, eNOS inactivation, decreased nitric oxide (NO) actions, and increased NO degradation, together with vasoconstriction counteracting against NO-induced vasodilatation. Catecholamines do not directly affect endothelial function but impair its function when blood pressure elevation by the amines is sustained. Endogenous opioids favorably affect endothelial function, which counteract deteriorating effects of other stress hormones and mediators. Inhibition of cortisol and endothelin-1 production, prevention of pro-inflammatory mediator accumulation, hypnotics, mirthful laughter, humor orientation, and lifestyle modification would contribute to the prevention and treatment for stress-related endothelial dysfunction and future serious cardiovascular disease.
