Social determinants and heat shock protein-70 among African American and non-Hispanic white women with atherosclerosis: a pilot study

Postmenopausal women treated for breast cancer with insulin resistance: clinical, analytical, cross-sectional

This study aims to investigate the potential association between serum levels of cytokines, HSP60, HSP70 and IR (HOMA-IR) in postmenopausal women. We conducted a cross-sectional study involving 381 postmenopausal women, including 94 with a breast cancer diagnosis and 278 without. We analyzed anthropometric and laboratory measurements. Immunoassays were used to measure cytokines (TNF-α, IL-10, and IL-6) as well as heat shock proteins (HSP) 60 and 70 in the serum using the ELISA technique. Women diagnosed with breast cancer showed higher levels of HOMA-IR, IL-6, TNF, and HSP60, and lower levels of IL-10 and HSP70 compared to women without cancer. An association was found between HSP70 and HOMA-IR only in women with breast cancer (β = 0.22, p = .030; without cancer: β = 0.04, p = .404), regardless of age, waist circumference, smoking, and physical activity. No associations were observed between cytokines, HSP60, and HOMA-IR in both groups of women. HSP70 is positively associated with IR in women diagnosed with breast cancer.

Subjective social status and nocturnal blood pressure dipping

OBJECTIVE

Low social status has been linked to cardiovascular disease. Subjective social status (SSS), which represents one's perceived position in a social hierarchy, has been suggested to predict health outcomes beyond objective measures of socioeconomic status. The present study examined if lower SSS is related to reduced nocturnal blood pressure (BP) dipping, a risk factor for cardiovascular disease.

METHODS

In this cross-sectional study, a community sample of 53 healthy adults underwent 24-h ambulatory BP monitoring. All participants provided information on SSS and objective measures of socioeconomic status (i.e., education, occupation, and income). SSS was measured in comparison to others in the country (national SSS) as well as in comparison to one's social environment (local SSS) using the German versions of the MacArthur Scales.

RESULTS

Analyses found that participants with low local SSS exhibited attenuated nocturnal diastolic blood pressure dipping (β = 0.29, 95% CI [0.01, 0.57], p = .043) and mean arterial pressure dipping (β = 0.29, 95% CI [0.01, 0.57], p = .041). These associations remained significant after adjusting for objective socioeconomic status. No significant associations between national SSS and cardiovascular measures were observed.

CONCLUSION

In conclusion, one's perceived social position in the social environment (i.e., local SSS) is associated with nocturnal BP dipping. Therefore, local SSS may be an important psychosocial factor linking social inequality and cardiovascular health.

A systematic review and meta-analysis of the Everyday Discrimination Scale and biomarker outcomes

Discrimination has consistently been associated with multiple adverse health outcomes. Like other psychosocial stressors, discrimination is thought to impact health through stress-related physiologic pathways including hypothalamic-pituitary-adrenal (HPA) axis activation, dysregulation of inflammation responses, and accelerated cellular aging. Given growing attention to research examining the biological pathways through which discrimination becomes embodied, this systematic review and meta-analysis synthesizes empirical evidence examining relationships between self-reported discrimination and four biomarker outcomes (i.e., cortisol, C-reactive protein (CRP), interleukin-6 (IL-6), and telomere length) among studies that have used the Everyday Discrimination Scale. We conducted a systematic review of studies discussing self-reported, everyday, or chronic discrimination in the context of health by searching Medline / PubMed (National Library of Medicine, NCBI), PsycInfo (APA, Ebsco) and Web of Science Core Collection (Clarivate). Twenty-five articles met the criteria for meta-analysis, with several reporting on multiple outcomes. Discrimination was associated with elevated CRP levels (r = 0.11; 95% CI: 0.01, 0.20, k = 10), though not cortisol (r = 0.05; 95% CI: -0.06, 0.16, k = 9), IL-6 (r = 0.05; 95% CI: -0.32, 0.42, k = 5), or telomere length (r = 0.03; 95% CI: -0.01, 0.07, k = 6). We identify several points of consideration for future research including addressing heterogeneity in assessment of biomarker outcomes and the need for longitudinal assessments of relationships between discrimination and biomarker outcomes.

Resilience in African American Women at Risk for Cardiovascular Disease: an Exploratory Study

African Americans (AAs) have a higher risk for cardiovascular disease (CVD) which is not fully explained by traditional CVD risk factors such as smoking, obesity, hypertension, and diabetes. Evidence demonstrates that chronic stress, low subjective status, and lack of social support play important roles in increasing the risk for CVD, particularly in minority women. Increasing evidence demonstrates that resilience may ameliorate the effect of social stressors on the development of CVD. However, little is known about the social context that may influence resilience in AA women. Therefore, the purpose of this exploratory study was to examine the predictors of resilience in AA women at risk for CVD. A cross-sectional sample of AA women (N = 104) participated in the study. Participants completed measures of resilience, subjective social status, social support, and general stress. Findings revealed that participants had low levels of resilience as measured by the Connor-Davidson Resilience Scale (mean = 50.3 ± 11.4) compared to norms. Results of the multiple linear regression analysis demonstrated that both subjective social status in relation to others in the USA (p = 0.021) and perceived social support (p < 0.001) predicted greater level of resilience. The model, controlling for age, marital status, income, level of education, and general stress, accounted for a significant proportion of variance (F[8,75] = 6.6, p < .001), explaining 41.7% of the variation in resilience. Results suggest that subjective social status and social support contribute to perceived resilience in AA women. Additional research is needed to assess the association of subjective social status and social support in longitudinal studies.

Is subjective social status a unique correlate of physical health? A meta-analysis

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

Chronic Pain and Psychological Distress Among Older Adults: A National Longitudinal Study

This research examines whether unobserved time-stable influences confound the association between chronic pain and psychological distress in older adults as well as how race and ethnicity combine with subjective social status (SSS) to modify the association. In a nationally representative longitudinal survey, holistically controlling for unobserved time-stable influences using fixed-effects models substantially reduces the pain-depression relationship and eliminates the overall pain-anxiety relationship. The association with depression is stronger for Black and Hispanic elders, illustrating a process of double-jeopardy. Black elders with severe pain experience lower anxiety, as do Black elders with moderate pain and low SSS, which we suggest may be due to the enervating effects of undermanaged pain. Black elders at high SSS experience greater anxiety with moderate pain. This research suggests that undermanagement of chronic pain among racial and ethnic minorities differentiates the association between pain and distress in late life and especially creates stronger associations with depression.

The Relationship Between Perceived Racism/Discrimination and Health Among Black American Women: a Review of the Literature from 2003 to 2013

OBJECTIVES

The purpose of this paper was to systematically review the literature investigating the relationship between perceived racism/discrimination and health among black American women.

METHODS

Searches for empirical studies published from January 2003 to December 2013 were conducted using PubMed and PsycInfo. Articles were assessed for possible inclusion using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2009 framework. In addition, the Agency for Healthcare Research and Quality (AHRQ) system for rating the strength of scientific evidence was used to assess the quality of studies included in the review.

RESULTS

Nineteen studies met criteria for review. There was mixed evidence for general relationships between perceived racism/discrimination and health. Consistent evidence was found for the relationship between adverse birth outcomes, illness incidence, and cancer or tumor risk and perceived racism/discrimination. Inconsistent findings were found for the relationship between perceived racism/discrimination and heart disease risk factors. There was no evidence to support the relationship between perceived racism/discrimination and high blood pressure.

CONCLUSIONS

There is mixed evidence to support the association between perceived racism/discrimination and overall objective health outcomes among black American women. The strongest relationship was seen between perceived racism/discrimination and adverse birth outcomes. Better understanding of the relationship between health and racism/discrimination can aid in identifying race-based risk factors developing primary prevention strategies. Future studies should aim to investigate the role of perceived racism/discrimination as a specific chronic stressor within discrete pathogenesis models.

Subjective social status and health

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.
