OBJECTIVE: To examine the cross-sectional associations of individual measures of SES-educational attainment and household income-and the joint effects of SES with PWV, as well as the SES-race interaction, in a cohort of older African American and White adults. METHODS: Data from the Atherosclerosis Risk in Communities (ARIC) Study were used to evaluate the cross-sectional associations of individual and joint SES [education and income] and carotid femoral pulse wave velocity (cfPWV), a subclinical marker of arterial stiffness, and the interaction of SES and race using adjusted multivariable linear regression models in a cohort of 3342 men and women aged 67-89 years free of CVD in 2011-2013. RESULTS: Participants were 64% female, 23% African American, mean cfPWV (12.3±3.5-African American and 11.6±3.9-White participants). Post-graduate education compared to less than high school was significantly associated with lower cfPWV (less stiffness) in African American (β = -1.28 m/s; 95% CI, -1.97, -0.59) but not in White (β = -0.69 m/s; 95% CI, -1.39, 0.01) participants. Income ≥$50K as compared to <$25K, was associated with lower cfPWV both in African American (β = -0.82 m/s; 95% CI, -1.42, -0.22) and White (β = -0.76 m/s; 95% CI, -1.19, -0.32) participants. The interaction of race and individual measures of SES on cfPWV in African American and White adults were not statistically significant (p-value >0.10). CONCLUSIONS: Higher SES was cross-sectionally associated with lower arterial stiffness in this cohort; the data did not support differences by race. Prospective studies of SES and cfPWV are needed to efficiently compare larger racially and regionally diverse populations with a wider range of socioeconomic profiles to better identify subgroup CVD risk.

BACKGROUND: The prevalence of hypertension (HTN) in Blacks is among the highest in the world. For Black women, 46% experience stage 2 HTN (blood pressure [BP] ≥140/90 mm Hg) as compared with 42% of Black men. Because of higher rates of stage 2 HTN, Black women have greater rates of cardiovascular disease and stroke. For reasons unknown, nonadherence to lifestyle modifications and antihypertensive medications continues. An understudied potential factor associated with poor adherence to the treatment regimen and negative health outcomes is stigma. OBJECTIVE: The aim of this study was to gain insight and describe the psychological factor of stigma as an influence on poorly controlled HTN in Black women. METHODS: Hypertensive Black women attending a 6-week self-management program were invited to participate in an open-ended questionnaire. Six groups were held with 62 women aged 24 to 70 years, with group size ranging from 10 to 15. Women anonymously wrote their answer to 2 questions to capture individual responses without group persuasion. Data were analyzed using thematic analysis. RESULTS: Five themes were generated inductively from the data and included (1) desire to get control, (2) shame and embarrassment, (3) obesity characterizations, (4) stereotype threats, and lastly, (5) disrupted normality. During member checking, younger participants were more vocal about stigma, whereas older participants did not view stigma as problematic. CONCLUSIONS: Hypertension stigma could potentially deter adherence to high BP treatment. Further research is needed to explore the prevalence of stigma in this population and its impact on behaviors that hinder BP control.

Study objective: To examine the associations of education and income and blood pressure (BP) in a socioeconomically diverse cohort of African-American (AA) women attending community BP screenings. Design setting and participants: This cross-sectional analysis used data from AA women (n = 972) 53 ± 14 years, enrolled between 2015 and 2019 in the 10,000-women hypertension community screening project in the metropolitan Atlanta area. OLS linear regression were used to examine the associations between SES (education and income) and BP after adjusting for age, body mass index (BMI), smoking, and lipids. Main outcomes and measures: Outcomes were systolic and diastolic BP (SBP, DBP). Measures of SES included education [high school ≤(HS), some college, and ≥college] and income-[<$24,000, $24,000-<$48,000, $48,000-$96,000, and ≥$96,000]. Sociodemographics, health history, anthropometrics and point of care non-fasting lipids were obtained. Results: Compared to women earning <$24,000, an income of ≥$96,000 (β = -5.7 mmHg, 95% CI: -9.9, -1.5, p = .01) was associated with a lower SBP in the minimally adjusted model. Subsequent adjustment for cardiovascular risk factors attenuated the association and was no longer significant. College and above versus ≤HS education was associated with a higher DBP in the minimally (ß = 2.7 mmHg, 95% CI: 0.2, 5.2, p = .03) and fully adjusted models (ß = 3.4 mmHg, 95% CI: 0.2, 6.5, p = .04). Conclusion: Income of ≥$96,000 was associated with a lower SBP while a college and above education was associated with a higher DBP. Findings underscore the need for increased cardiovascular risk awareness and education targeting higher SES AA women attending community BP screenings.

Importance: Low socioeconomic status (SES) in the form of educational level and income has been linked to greater cardiovascular risk across cohorts; however, associations have been inconsistent for African American individuals. Net worth, a measure of overall assets, may be a more relevant metric, especially for African American women, because it captures longer-term financial stability and economic reserve. Objective: To examine whether net worth is associated with increased ambulatory blood pressure (ABP), a marker of cardiovascular disease (CVD) risk, independent of educational level and income, in young to middle-aged African American women. Design, Setting, and Participants: A cross-sectional, community-based study conducted in the southeastern US was performed using 48-hour ambulatory BP monitoring. Participants included 384 African American women aged 30 to 46 years without clinical CVD recruited between December 16, 2016, and March 21, 2019; data analysis was performed from September 2020 to December 2021. Exposures: Self-reported net worth (total financial assets minus debts), self-reported educational level, and self-reported income. Main Outcomes and Measures: Mean daytime and nighttime BP levels, assessed via 48-hour ABP monitoring and sustained hypertension (ABP daytime and clinic BP ≥130/80 mm Hg). Results: The 384 African American women in this study represented a range of SES backgrounds; mean (SD) age was 38.0 (4.3) years. Excluding 66 women who were not receiving antihypertensive medications, in linear regression models adjusted for age, marital status, educational level, family income, and family size, women reporting a negative net worth (debt) had higher levels of daytime (β = 6.7; SE = 1.5; P <.001) and nighttime (β = 6.4; SE = 1.4; P <.001) systolic BP, compared with women reporting a positive net worth. Similar associations were observed with sustained hypertension: women reporting a negative net worth had 150% higher odds (odds ratio, 2.5; 95% CI, 1.3-4.7) of sustained hypertension than those reporting a positive net worth. Associations remained significant after additional adjustments for smoking, body mass index, psychosocial stress due to debt, and depressive symptoms and were similar, although attenuated, when women receiving antihypertensive medications were included and treatment was controlled for in all analyses. Conclusions and Relevance: In this cross-sectional study, having a negative net worth (ie, debt) was associated with elevated BP in African American women, independent of traditional indicators of SES. This finding suggests that limited assets or a lack of economic reserve may be associated with poor CVD outcomes in this at-risk group.
