RESUMO

Although orthostatic hypotension (OH) has long been recognized as a manifestation of autonomic dysfunction, a growing body of literature has identified OH as a common comorbidity of hypertension. This connection is complex, related to pathophysiology in blood pressure regulation and the manner by which OH is derived as the difference between 2 blood pressure measurements. While traditional therapeutic approaches to OH among patients with neurodegenerative disorders focus on increasing upright blood pressure to prevent cerebral hypoperfusion, the management of OH among patients with hypertension is more nuanced; resting hypertension is itself associated with adverse outcomes among these patients. Although there is substantial evidence that intensive blood pressure treatment does not cause OH in the majority of patients with essential hypertension, some classes of antihypertensive agents may unmask OH in patients with an underlying autonomic impairment. Practical steps to manage OH among adults with hypertension start with (1) a thorough characterization of its patterns, triggers, and cause; (2) review and removal of aggravating factors (often pharmacological agents not related to hypertension treatment); (3) optimization of an antihypertensive regimen; and (4) adoption of a tailored treatment strategy that avoids exacerbating hypertension. These strategies include countermaneuvers and short-acting vasoactive agents (midodrine, droxidopa). Ultimately, further research is needed on the epidemiology of OH, the impact of hypertension treatment on OH, approaches to the screening and diagnosis of OH, and OH treatment among adults with hypertension to improve the care of these patients and their complex blood pressure pathophysiology.

RESUMO

OBJECTIVE: Life stressors have been linked to cardiovascular risk; however, studies typically focus on stressors that directly impact the individual, that is, personal stressors. Research suggests that women, particularly African-American women, may be more vulnerable to network stressors that involve family members and friends-potentially due to norms around needing to be a "Superwoman." Yet few studies have examined these phenomena. METHOD: We examined associations between network, versus personal, stressors, and elevated blood pressure (BP) in N = 392 African-American women aged 30-46. Questionnaire-assessed negative life events were classified into upsetting network or personal stressors. BP was assessed in clinic and via 48-hr ambulatory monitoring. Linear and logistic regression models examined associations between type of stressors and 48-hr daytime and nighttime systolic BP (SBP) and diastolic BP (DBP), and sustained hypertension after adjusting for relevant covariates. Interactions with questionnaire-assessed superwoman schema (SWS) were tested in exploratory analyses. RESULTS: In age and sociodemographic-adjusted models, network stressors were significantly associated with daytime SBP, ß (SE) = 2.01 (0.51), p ≤ .0001, and DBP, ß (SE) = 1.59 (0.37), p ≤ .0001, but personal stressors were not (p values > .10). Associations persisted after adjustment for cardiovascular and psychosocial risk factors. Patterns were similar for nighttime BP and sustained hypertension. There were no interactions with SWS. CONCLUSIONS: Network, but not personal, stressors were associated with elevated rates of daytime SBP and DBP, as well as sustained hypertension in African-American women, irrespective of SWS endorsement. Future research is needed to determine whether stress-management interventions focused on network stressors might impact BP in this high-risk population.

RESUMO

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 (ß = -1.28 m/s; 95% CI, -1.97, -0.59) but not in White (ß = -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 (ß = -0.82 m/s; 95% CI, -1.42, -0.22) and White (ß = -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.

RESUMO

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 (ß = -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.

RESUMO

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 (ß = 6.7; SE = 1.5; P < .001) and nighttime (ß = 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.

RESUMO

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.

RESUMO

BACKGROUND: Poor adherence to hypertensive medication has been suggested to be a major contributor to uncontrolled hypertension (HTN) in African Americans. The impact that social determinants have on the various patient-level factors, including HTN beliefs, mental well-being, and social support, may provide insight into the development and tailoring of culturally targeted interventions, thus improving adherence. OBJECTIVE: The aim of this study was to examine the relationships of exposures to contextualized racial and gendered stressors, social support, and depressive symptoms with HTN illness perceptions and blood pressure (BP) medication adherence. METHODS: Participants (N = 85) were hypertensive African-American women aged 18 to 45 years (mean [SD], 39.2 [5.4] years) recruited from the community setting and outpatient medical clinics in a large metropolitan city. Hypertension illness beliefs were assessed using the 8-item Brief Illness Perception Questionnaire ("How much does your blood pressure affect your life?") and medication adherence was assessed with the 7-item Adherence to Refills and Medication Scale ("How often do you forget to take your BP medicine?"). Logistic regression analyses were performed to examine the associations with medication adherence and linear regression analyses were performed to examine the associations of continuous variables and HTN illness perceptions. RESULTS: The sample was predominantly nonadherent (81.2%). In the adjusted multivariable regression model, systolic BP (odds ratio, 0.95; P = .05) and the "Consequence" dimension of HTN beliefs (odds ratio, 0.76; P = .02) were associated with medication adherence. In the adjusted linear regression model, systolic BP (ß = 0.22, P < .01) and depressive symptoms (ß = 1.11, P < .01) were associated with HTN illness beliefs. CONCLUSIONS: Assessing beliefs and the mental well-being before initiating BP medications is essential for adherence and BP control.

RESUMO

Hypertension, a modifiable risk factor of cardiovascular disease, is largely responsible for the disproportionate morbidity and mortality in black women. Black women 20 years of age and older have a higher prevalence of HTN compared to white women (44% vs 28%). Poor adherence and non-adherence to hypertensive medications have been strongly indicated as a primary contributor to the early onset of disparity in cardiovascular disease morbidity and mortality experienced by black people. The purpose of this study was to examine medication adherence in black women relative to sociodemographic, clinical, cultural context, psychosocial, cognitive, and behavioral factors. This was a prospective, descriptive cross-sectional study of N = 85, hypertensive black women, with mean age of 39 ± 5.4 years, 18-45 years of age. Variables and measures included: sociodemographic characteristics, clinical, adverse social stressors, psychosocial, cognitive-behavioral factors, and medication adherence. Descriptive statistics, correlations, multivariate logistic regressions, and moderation analysis were tested. 81.2% (n = 69) of the sample was categorized as non-adherent. SBP was the only clinical covariate associated with HTN medication adherence. HTN illness perceptions, composite score, resilient coping, depressive symptoms, exposure to lifetime gender, and racial stressors, were not associated with HTN medication adherence. Using multivariate logistic regression, decreased SBP and lower scores on the "Consequence" dimension of the HTN illness perception scale were associated with medication adherence (χ2  = 10.53, P = .001). Adherence was associated with both the "Consequence" and "Identity" dimensions of the HTN illness perception scale indicating the need and importance for clinicians to have open and honest communication regarding HTN and its treatment in facilitating adherence.

RESUMO

BACKGROUND: African Americans are disproportionately affected by hypertension and have lower medication adherence when compared to other racial groups. Antecedent factors such as beliefs surrounding hypertension, the presence or absence of social support, and depressive symptoms have not been extensively studied collectively in relation to hypertension medication adherence in African Americans. OBJECTIVE: To determine the associations among demographic and clinical factors, depressive symptoms, hypertension beliefs, and social support with blood pressure medication adherence in middle-aged African American adults with a diagnosis of hypertension. METHODS: A cross-sectional study of (N = 120) African Americans (mean age, 49 years; 22.5% men) with a current diagnosis of metabolic syndrome, including hypertension, who reported having and taking a prescribed blood pressure-lowering medication were included. Descriptive statistics, bivariate correlation analysis, and logistic regression using odds ratio were used to examine the effects of high blood pressure beliefs, social support, and depression on medication adherence. RESULTS: A small but significant relationship was found between medication adherence and number of comorbidities (r = 0.19, P = .04). In a multivariate regression model, after controlling for gender, comorbidities remained associated with medication adherence (ß = 0. 77, P = .04). Depressive symptoms, high blood pressure beliefs, and social support did not have a significant relationship with medication adherence. CONCLUSIONS: Multiple comorbidities may have a positive impact upon medication adherence. Further study is needed in a larger sample of African Americans who have a diagnosis of hypertension in addition to other comorbidities requiring medication management.
