ABSTRACT
The prevalence of hypertension (HTN) among Black women in the United States has increased over the past 10 years with a decline in levels of HTN awareness, treatment, and control. Higher death rates occur in Black women from HTN-related diseases when compared with women of other racial/ethnic groups. Although interventions aimed at self-care/self-management are vital to adults becoming the cornerstone of their own health and well-being, there is a paucity of research in Black women. This randomized controlled pilot trial substudy examined the influence of a Chronic Disease Self-Management Program (CDSMP) with tailored coaching versus the CDSMP alone on blood pressure (BP), weight, and scores on self-care questionnaires and medication adherence for Black women with HTN over 9 months. Eighty-three women who had completed the CDSMP were randomly assigned to coaching or no coaching. Median age was 54 years and the time since the HTN diagnosis was 9 years. Significant differences were noted in self-care maintenance and management over time with better self-care in the treatment group. Though not significant, both groups denoted a trend toward better medication adherence. Almost 60% of the participants in both groups showed improvements in their systolic and/or diastolic BP. However, there was no significant difference between the study groups' BP and weight variables. The CDSMP was effective in decreasing BP and improving medication adherence. Further research is needed to evaluate effective coaching strategies that motivate Black women with HTN toward self-care management.

Fatigue and stress may affect medication adherence. This study explored fatigue, stress, and blood pressure (BP) medication adherence in Black and White adults (N= 152) who had experienced a myocardial infarction. Over half of the sample (55%) reported fatigue as moderate to severe. The regression model explained up to 40% of the variance (p < .001) with fatigue and race significantly predicting adherence. Black participants reported fatigue causing distress (r =.40), and White participants reported greater association of fatigue severity-related BP medication adherence (r =.49). Our findings support considering racial differences when evaluating fatigue associated with BP medication adherence.
ABSTRACT
BACKGROUND: Mitochondrial ATP production requires a small electron carrier, coenzyme Q10 (CoQ10), which has been used as adjunctive therapy in patients with cardiovascular disease (CVD) and hypertension (HTN) because of its bioenergetics and antioxidant properties. Randomized controlled trials (RCTs) beyond the last 2 decades evaluating CoQ10 added to conventional therapy resulted in mixed results and were underpowered to address major clinical endpoints. OBJECTIVES: The objective of this systematic review was to examine the impact of CoQ10 supplementation on older adults with CVD or HTN in the last 2 decades (2000-2020). METHODS: PubMed/Medline, Cochrane Database, CINAHL, and Google Scholar databases were searched systematically, and references from selected studies were manually reviewed, to identify RCTs or crossover studies evaluating the efficacy of CoQ10 supplementation. Data extracted from selected studies included trial design and duration, treatment, dose, participant characteristics, study variables, and important findings. RESULTS: A total of 14 studies (1067 participants) met the inclusion criteria. The effect of CoQ10 supplementation was examined among predominantly older adult males with heart failure (HF) (n = 6), HTN (n = 4), and ischemic heart disease (n = 3), and preoperatively in patients scheduled for cardiac surgery (n = 1). CoQ10 supplementation in patients with HF improved functional capacity, increased serum CoQ10 concentrations, and led to fewer major adverse cardiovascular events. CoQ10 had positive quantifiable effects on inflammatory markers in patients with ischemic heart disease. Myocardial hemodynamics improved in patients who received CoQ10 supplementation before cardiac surgery. Effects on HTN were inconclusive. CONCLUSIONS: In predominantly older adult males with CVD or HTN, CoQ10 supplementation added to conventional therapy is safe and offers benefits clinically and at the cellular level. However, results of the trials need to be viewed with caution, and further studies are indicated before widespread usage of CoQ10 is recommended in all older adults.

BACKGROUND: As recurrent myocardial infarctions (MIRs) constitute almost a third of the annual incidence of myocardial infarction, identifying the traditional and novel variables related to MIR is important. OBJECTIVE: The aim of this study was to examine modifiable cardiac risks, adiposity, symptoms associated with inflammation (fatigue, depression, sleep) and inflammatory cytokines, and MIR by sex and race. METHODS: Using a cross-sectional descriptive design, we recruited a convenience sample of adults (N = 156) discharged with first myocardial infarction or had MIR in the last 3 to 7 years. Surveys measured demographics, cardiac risk factors, depression, sleep, and fatigue. Anthropometric measures and cytokines tumor necrosis factor-α, interleukin-6, and high-sensitivity C-reactive protein (hsCRP) were obtained. A maximum likelihood regression was calculated to predict MIR. RESULTS: The sample included 57% male and 30% Black participants, and the mean (SD) age was 65 (12) years. The hsCRP was the only cytokine related to symptoms: fatigue ( r = 0.309, P < .001) and depression ( r = 0.255, P = .002). An MIR was not associated with race despite White participants reporting better sleep ( t146 = -3.25, P = .002), lower body mass index ( t154 = -3.49, P = .001), and fewer modifiable risk factors ( t152 = -2.05, P = .04). An MIR was associated with being male, higher hsCRP and tumor necrosis factor-α levels ( P < .001), and higher inflammatory symptoms of fatigue ( P = .04), depression ( P = .01), and poor sleep ( P < .001). CONCLUSION: Further examination of biomarkers to understand the mechanisms associated with inflammatory symptoms of fatigue, depression, and poor sleep and MIR is needed.

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.

In the United States, hypertension (HTN) is the leading risk factor for cardiovascular disease, and a more significant health problem for Blacks compared with other racial/ethnic groups. The prevalence of HTN in Black women is among the highest in the world, underscoring the need for effective prevention and management approaches for blood pressure (BP) control. We developed a two-arm randomized controlled trial repeated measures design study for improving HTN self-management among Black women. The study tests whether the Chronic Disease Self-Management Program (CDSMP) combined with interactive technology-enhanced coaching, can improve BP control and adherence to treatment (e.g., medication-taking, physical activity, calorie intake, and weight management) compared with the CDSMP alone. Repeated measurements were conducted at 3, 6, and 9 months. A sample of 90 community-dwelling Black women with uncontrolled Stage 1 HTN (BP ≥ 130/80) were enrolled, completed CDSMP training, and randomized. This study will contribute to our understanding of novel methods to empower Black women to increase their active involvement in self-care management of HTN.

BACKGROUND: Hypertension (HTN) is a global public health issue. Self-care is an essential component of HTN treatment, but no instruments are available with which to measure self-care of HTN. OBJECTIVES: The purpose of this study is to test the psychometric properties of the Self-care of Hypertension Inventory (SC-HI). METHODS: Using the Self-care of Chronic Illness theory, we developed a 24-item measure of maintenance, monitoring, and management appropriate for persons with chronic HTN, tested it for content validity, and then tested it in a convenience sample of 193 adults. Exploratory factor analysis was used to identify measure structure. Cronbach's α and factor determinacy scores and were used to assess reliability. Validity was tested with the Medical Outcomes Study General Adherence Scale and the Decision Making Competency Inventory. RESULTS: Seventy percent of the sample was female; mean age was 56.4 ± 13 years; mean duration of HTN was 11 ± 9 years. Removal of 1 item on alcohol consumption resulted in a unidimensional self-care maintenance factor with acceptable structure and internal consistency (α = .83). A multidimensional self-care management factor included "consultative" and "autonomous" factors (factor determinacy score = 0.75). A unidimensional confidence factor captured confidence in and persistence with each aspect of self-care (α = .83). All the self-care dimensions in the final 23-item instrument were associated with treatment adherence and several with decision making. CONCLUSION: These findings support the conceptual basis of self-care in patients with HTN as a process of maintenance, monitoring, and management. The SC-HI confidence scale is promising as a measure of self-efficacy in self-care.

Black women have the highest rate of hypertension (HTN) in the U.S. and perhaps the world. Because they are deemed the most religiously devout group in the U.S., it is plausible that faithfulness to spiritual/religious practices may yield more adherence to HTN medication regimens. This study examined spiritual/religious beliefs in relation to antihypertensive medication adherence in Black women with HTN. Although results showed no association between beliefs and adherence, women who developed trusting relationships with their healthcare provider were more likely to be adherent to their medications.

Black women have the highest prevalence of hypertension in the world, and depression is associated with both hypertension and lack of health promoting behaviors. Thus, it is important to identify factors that may contribute to depression in hypertensive women. This cross-sectional study was conducted with a convenience sample of 80 black women ages 18-60 who were prescribed anti-hypertensive medication. Data were collected using self-report instruments. The study showed that lower income level, greater number of comorbidities, lower active coping scores, and poorer medication adherence were significantly associated with higher depression scores. These findings have important implications for the development of screening protocols and interventions for black women.

Hypertension is the main cause of cardiovascular disease, especially in women. Black women (58%) are affected by higher rates of hypertension than other racial/ethnic groups contributing to increased cardio-metabolic disorders. To decrease blood pressure (BP) in this population, a pilot randomized controlled trial was conducted to examine the effects of Interactive Technology Enhanced Coaching (ITEC) versus Interactive Technology (IT) alone in achieving BP control, adherence to antihypertensive medication, and adherence to lifestyle modifications among Black women diagnosed with and receiving medication for their hypertension. Participants completed a 6-week Chronic Disease Self-Management Program (CDSMP), and 83 participants were randomly assigned to ITEC versus IT. Participants were trained to use three wireless tools and five apps that were synchronized to smartphones to monitor BP, weight, physical activity (steps), diet (caloric and sodium intake), and medication adherence. Fitbit Plus, a cloud-based collaborative care platform was used to collect, track, and store data. Using a mixed-effects repeated measures model, the main effect of group means indicated no significant difference between the treatment and referent groups on study variables. The main effect of time indicated significant differences between repeated measures for systolic BP (p < .0001), weight (p < .0001), and steps (p = .018). An interaction effect revealed differences over time and was significant for study measures except diastolic BP. An important goal of this preliminary analysis is to help Black women prioritize self-care management in their everyday environment. Future research is warranted in a geographically broader population of hypertensive Black women.

Objective: The purpose of this study was to explore perceived ease of use, usability, and the feasibility of using mobile health applications to manage hypertension self-care in rural Black older adults with hypertension. Methods: A convergent parallel mixed method design was used to study a purposeful sample of 30 Black older adults (29 females, 1 male) from rural East Texas. Quantitative data included demographic characteristics and measured blood pressure, height, and weight, along with questionnaires: the Hill-Bone Compliance to High Blood Pressure Therapy Scale, the Krousel-Wood Medication Adherence Scale-4, and the Technology Acceptance Model Questionnaire (adapted). Qualitative data were obtained from five focus groups and analyzed using thematic analysis. Results: Mean age was 66.3 ± 9.6 years. Less than half of the participants (46.7%) had a systolic and/or diastolic blood pressure >130/80. Greater participant adherence was noted with the Hill-Bone Compliance scale (63.3%) than the Krousel-Wood scale (23.3%). With the Technology Acceptance Model, perceived ease of use was significantly correlated with behavioral intention (r = 0.654, p < 0.000) and perceived usefulness (r = 0.585, p < 0.001), while behavioral intention was negatively associated with age r = -0.047 (p=0.009). Focus group data revealed five themes: 1) useful, 2) counterintuitive, 3) communication, 4) comfort with the status quo, and 5) educate/show me how. Conclusion: Smartphone technology and other health-related computer technologies were not preferred by older adults in this study due to limited digital literacy. Simplicity and easy navigation in the design of mHealth apps are needed to improve treatment adherence and blood pressure control in rural older adults with hypertension. Clinical Relevance: Mobile health applications have the potential to increase self-management of chronic hypertension if users are digitally literate. Health-care providers need to assess older patients for digital literacy and offer educational support and assistance.
ABSTRACT
ABSTRACT: The prevalence of hypertension in Black women (57.6%) is among the highest in the world. Many of those who identify as Black do not readily adhere to prescribed antihypertensive medications nor persist with long-term therapy. This qualitative study describes self-reported approaches used by Black women with consistent adherence and persistence to medication-taking for BP control.

BACKGROUND: Black women in the USA have the highest prevalence rate of hypertension (HTN) contributing to a higher risk of organ damage and death. Research has focused primarily on poorly controlled HTN, negative belief systems, and nonadherence factors that hinder blood pressure control. No known research studies underscore predominantly Black women who report consistent adherence to their antihypertensive medication-taking. The purpose of this study was to describe self-care management strategies used by Black women who self-report consistent adherence to their antihypertensive medication and to determine the existence of further participation in lifestyle modifications, such as eating a healthy diet and increasing physical activity. METHODS: Using a qualitative descriptive design, four focus groups with a total of 20 Black women aged 25-71 years were audio-taped. Transcripts were analyzed using qualitative content analysis. Participants were included in the study if they scored perfect adherence on the medication subscale of the Hill-Bone Compliance to High Blood Pressure Therapy Scale. RESULTS: Medication adherence was predicated on three themes: HTN experience, involvement with treatment regimen, and a strong motivated mentality. Black women would benefit from treatment approaches that are sensitive to 1) diverse emotional responses, knowledge levels, and life experiences; 2) two-way communication and trusting, collaborative relationships with active involvement in the treatment regimen; 3) lifestyle modifications that focus on health benefits and individual preferences; and 4) spiritual/religious influences on adherence. CONCLUSION: The use of self-care management strategies to enhance antihypertensive medication adherence is key to adequate blood pressure control and the reduction of cardiovascular events. This study provides preliminary insight for future research to develop interventions to aid those Black women who struggle with medication adherence and are disproportionately impacted by HTN.
ABSTRACT
BACKGROUND: Fatigue is prevalent after myocardial infarction (MI) and is a barrier to physical activity (PA). Because PA is an important health behavior in preventing or delaying recurrent MIs, examining the influence of biophysical markers and fatigue on PA is important as a prerequisite to developing effective interventions. OBJECTIVE: This study compared PA in 34 men and 38 women, aged 65 and older, 6-8 months post MI, and examined the influence of biophysiological measures and fatigue on PA in this sample. METHODS: Using a cross-sectional descriptive correlational design, adults completed a demographic form that included documentation of blood pressure, heart rate, height and weight; the Revised Piper Fatigue Scale (RPFS), and the Community Healthy Activities Model Program for Seniors Physical Activity Questionnaire for Older Adults, and blood collection for measurement of hemoglobin (Hgb), interleukin-6, and B-natriuretic peptide. RESULTS: There were no differences in frequency of PA between older men and older women; however, men reported a higher intensity of PA (p = .011). When controlling for sex, age, and biophysiological measures, the RPFS significantly explained 16% of the variance in the frequency of PA (p = .03), with no individual subscale serving as a significant predictor. The RPFS behavior/severity subscale explained 31% of the variance in energy expended on all PA (p < .001) and 40% of the variance in energy expended on moderate-intensity PA (p < .001). CONCLUSION: The older adults participating in this study did not participate in the recommended levels of PA, and fatigue significantly influenced PA post MI.

BACKGROUND: Black women have the highest prevalence of hypertension in the world. Reasons for this disparity are poorly understood. The historical legacy of medical maltreatment of Blacks in the U.S. provides some insight into distrust in the medical profession, refusal of treatment, and poor adherence to treatment regimens. METHODS: Black women (N = 80) who were prescribed antihypertensive medications were recruited from urban communities in North Carolina. Study participants completed the Trust in Physician and Hill-Bone Compliance to High Blood Pressure Therapy questionnaires. An exact discrete-event model was used to examine the relationship between trust and medication adherence. RESULTS: Mean age of study participants was 48 ± 9.2 years. The majority of participants (67%) were actively employed and 30% had incomes at or below the federal poverty level. Increasing levels of trust in the health care provider was independently associated with greater medication adherence (P Trend = 0.015). CONCLUSION: Black women with hypertension who trusted their health care providers were more likely to be adherent with their prescribed antihypertensive medications than those who did not trust their health care providers. Findings suggest that trusting relationships between Black women and health care providers are important to decreasing disparate rates of hypertension.
ABSTRACT
The prevalence of hypertension in African Americans exceeds that of all other racial/ethnic groups in the world. Hypertension in African Americans is less likely to be controlled and this problem is further complicated by failure to adhere to prescribed hypertension management regimens. Oftentimes, health care providers give African American patients with hypertension multiple health "rules" to follow that may arouse reactance behaviors: that is, patients may choose to do the opposite of what they are told to do. The theory of psychological reactance offers a framework for understanding the relationship between freedom of choice and adherence to hypertension regimens in African Americans.
