Improving hypertension knowledge, medication adherence, and blood pressure control: A feasibility study

The impact of the COVID-19 pandemic on the socioeconomic gradient of hypertension

The COVID-19 pandemic has brought into sharp focus the impact of socioeconomic factors on hypertension outcomes. This review examines the implications of the pandemic on the socioeconomic gradient of hypertension and explores the physiological and pathophysiological processes underlying this relationship. Changes in socioeconomic factors have disproportionately affected individuals with lower socioeconomic status, leading to adverse hypertension outcomes. The pandemic-related stressors, coupled with social isolation and disrupted daily routines, have contributed to elevated stress levels among individuals, particularly those with lower socioeconomic status. Equitable access to healthcare, enhancing health literacy and patient empowerment, and addressing social determinants of health are essential components of hypertension management strategies. By recognizing the specific challenges faced by individuals with lower socioeconomic status and implementing targeted interventions, public health efforts can help reduce the socioeconomic gradient of hypertension.

Knowledge and acceptance associated with medication adherence among hypertension individuals in Aceh province, Indonesia

Low adherence to anti-hypertensive medication is observed among individuals in Aceh, the westernmost province of Indonesia. Since uncontrolled hypertension has the potential to develop into a life-threatening disease, exploring medication adherence among this specific population is essential. Therefore, this study aimed to evaluate knowledge and acceptance associated with medication adherence among hypertensive individuals in Aceh Province. A cross-sectional study was conducted from March to July 2023 on 534 respondents diagnosed with hypertension, who were selected using the random sampling method. Demographic characteristics collected included body height and weight, age, gender, education, ethnicity, and occupation. Acceptance and knowledge were measured through a set of standardized questionnaires while the Morisky Medication Adherence Scale-8 was used for evaluating medication adherence. Logistic regression with a multinomial model was used to assess the correlations of acceptance and knowledge with medication adherence. The results showed that only 28.5 % of the respondents had high adherence to anti-hypertensive medication. Furthermore, a high level of acceptance towards hypertension significantly predicted medication adherence (p < 0.001; OR = 9.14 [95%CI: 3.49-23.94]). Knowledge about dosing frequency, the benefits of low-fat and sodium diets, and the negative impacts of drinking alcohol were correlated with high-level adherence (p < 0.01). Meanwhile, knowledge about renal complications correlated negatively with adherence level (p = 0.002; OR = 0.32 [95%CI: 0.16-0.66]). In conclusion, this study showed that acceptance and knowledge of hypertension correlated with the level of medication adherence.

Community-Based Culturally Tailored Education Programs for Black Communities with Cardiovascular Disease, Diabetes, Hypertension, and Stroke: Systematic Review Findings

BACKGROUND

Community-based culturally tailored education (CBCTE) programs for chronic diseases may reduce health disparities; however, a synthesis across chronic diseases is lacking. We explored (1) the characteristics and outcomes of CBCTE programs and (2) which strategies for culturally appropriate interventions have been used in CBCTE programs, and how they have been implemented.

METHODS

A systematic review was conducted by searching three databases to identify empirical full-text literature on CBCTE programs for Black communities with cardiovascular disease, hypertension, diabetes, or stroke. Studies were screened in duplicate, then data regarding study characteristics, participants, intervention, and outcomes were extracted and analyzed. Cultural tailoring strategies within programs were categorized using Kreuter and colleagues' framework.

RESULTS

Of the 74 studies, most were conducted in the USA (97%) and delivered in one site (53%; e.g., church/home). CBCTE programs targeted diabetes (65%), hypertension (30%), diabetes and hypertension (1%), cardiovascular disease (3%), and stroke (1%). Reported program benefits included physiological, medication-related, physical activity, and literacy. Cultural tailoring strategies included peripheral (targeted Black communities), constituent-involving (e.g., community informed), evidential (e.g., integrated community resources), linguistic (e.g., delivered in community's dialect/accent), and sociocultural (e.g., integrated community members' religious practices).

CONCLUSIONS

CBCTE programs may have beneficial outcomes, but a small sample size limited several. The strategies identified can be adopted by programs seeking to culturally tailor. Future interventions should clearly describe community members' roles/involvement and deliver programs in multiple locations to broaden reach.

Influencing factors of medication literacy among community-dwelling older adult patients with hypertension: a study based on social learning theory

Objective: This study aimed to examine the factors affecting medication literacy in community-dwelling older adults with hypertension, guided by social learning theory. It sought to analyze the pathways these factors influenced and provide a theoretical foundation for designing targeted intervention programs. Study design: This is a cross-sectional study. Methods: From October 2022 to February 2023, a total of 432 community-dwelling older adults with hypertension from Linghe District, Guta District, and Taihe District, Jinzhou City, Liaoning Province, China, were selected using convenience sampling. Data were collected using a socio-demographic questionnaire, a medication literacy questionnaire, the Brief Illness Perception Questionnaire, the General Self-efficacy Scale, and the Perceived Social Support Scale. The collected data were analyzed with Kruskal-Wallis and Mann-Whitney tests, correlation analysis, multiple stepwise regression analysis, and structural equation modeling (SEM). Results: The medication literacy score among the participants was 3.83 ± 1.91. Multi-factor analysis revealed key factors affecting their medication literacy, including blood pressure-control status, utilization of community health education resources, receiving guidance for medication usage, marital status, number of annual visits, social support, self-efficacy, and disease perception. The SEM based on social learning theory showed that general self-efficacy mediated the relationship between social support, disease perception, and medication literacy. Conclusion: The present study developed a model and provided potential intervention strategies to improve medication literacy, knowledge, and safety among community-dwelling older adults with hypertension, considering the relationships between the identified variables.

Patient activation, adherence to hypertension treatment plans and blood pressure control in Saudi Arabia: a cross-sectional study

OBJECTIVES

To explore the relationship between patient activation, adherence to hypertension treatment plans, blood pressure control and other important demographic factors.

DESIGN

A cross-sectional study.

SETTING

Primary healthcare centres in Riyadh province, Saudi Arabia.

PARTICIPANTS

A total of 114 adults with hypertension, including 68 men and 46 women.

OUTCOME MEASUREMENTS

Blood pressure control is achieved if (a) patients under 80 years of age with treated hypertension have blood pressure under 140/90 mm Hg or (b) patients aged 80 years or over with treated hypertension have blood pressure under 150/90 mm Hg. Secondary outcomes included patient activation, adherence to hypertension treatment plans and demographic factors (age, gender, education, income and comorbidity). Data were analysed using Pearson's correlation and multiple regression models.

RESULTS

57% (n=66) of participants did not achieve the ideal blood pressure target. Perfect adherence to hypertension treatment plans was significantly associated with lower systolic (r=-0.38, p<0.01) and diastolic blood pressure (r=-0.50, p<0.01). Age was significantly correlated with patient activation (r=-0.20, p<0.05) and diastolic blood pressure (r=-0.33, p<0.01). There was no statistically significant association between Patient Activation Measure, systolic blood pressure and diastolic blood pressure. In the hierarchical regression analysis, adherence to hypertension treatment plans was found to be a significant predictor and explained 15% of the variance in systolic blood pressure (β=-0.36, p<0.001) and 26% of the variance in diastolic blood pressure (β=-0.51, p<0.001).

CONCLUSION

The individual and family self-management theory can serve as an effective theory for understanding the key factors in achieving ideal blood pressure target. The majority of patients with hypertension reported lower levels of activation and poor blood pressure control. Inadequate adherence to treatment plans was related to poor blood pressure control. This work is pivotal in devising self-management interventions to assist patients in the management of hypertension disease, especially in Saudi Arabia.

Modifiable Risk Factors for Dementia Among Migrants, Refugees and Asylum Seekers in Australia: A Systematic Review

While the prevalence of non-communicable disease risk factors is understood to be higher among migrants than for people born in host nations, little is known about the dementia risk profile of migrants, refugees and asylum seekers. This systematic review examines published literature to understand what is currently reported about 12 identified modifiable risk factors for dementia among migrants, refugees, and asylum seekers residing in Australia. Three literature databases (PubMed/CINAHL/MEDLINE) were systematically searched to find articles reporting excessive alcohol consumption, traumatic brain injury, air pollution, lack of education, hypertension, hearing impairment, smoking, obesity, depression, physical inactivity, diabetes, and limited social contact in Australia's migrant, refugee and asylum seeker population samples. Papers were systematically reviewed following PRISMA guidelines. A total of 763 studies were found, of which 676 articles were excluded, and 79 articles remained. Despite wide variability in study design, size and purpose, the prevalence and correlates of modifiable risk factors of dementia appears markedly different among the studied samples. Compared with Australian-born participants, migrant samples had a higher prevalence of depression, social isolation, physical inactivity and diabetes mellitus. Insufficient information or conflicting evidence prevented inference about prevalence and correlates for the remaining dementia risk factors. A better understanding of the prevalence and correlates of modifiable dementia risk factors is needed in Australia's migrant, refugee and asylum seeker populations. This information, together with a deeper understanding of the contextual and cultural contributing factors affecting people who arrive in Australia through differing pathways is needed before preventive interventions can be realistically targeted and sensitively implemented.

Evaluation of Psychological Distress, Self-Care, and Medication Adherence in Association with Hypertension Control

Background. Most of the patients with hypertension (HTN) who undergo medical therapy unaccompanied by psychological and behavioral interventions may not achieve their goal in HTN treatment. Self-care is a key factor in controlling HTN. Given that depression, stress, and anxiety are the most psychological disorders in chronic illnesses. Their impact on self-care, quality of life, and HTN control must be studied more. Methods. We analyzed the difference in medication adherence in 252 patients with low vs. high psychological distress. Also, patients with controlled and uncontrolled HTN were compared according to their psychological distress scores. We further assessed the relation of psychological distress, self-care, and medication adherence with patients’ demographic characteristics. Results. 61.3% of our participants were female with a mean age of 60.6 ± 11.35 and male participants had a mean age of 60.5 ± 11.55. The psychological distress score was significantly higher in women with uncontrolled HTN ( $p$ value = 0.044). Also, individuals with controlled HTN tend to have a higher medication adherence score ( $p$ value = 0.01) and higher self-care score ( $p$ value = 0.033). Hypertensive females had a higher psychological distress score (3.35 ± 2.05) and a lower self-care score (64.05 ± 8.16). There was a positive relationship between age and drug adherence. The self-care score was higher (65.95 ± 7.88) in patients having lower psychological distress levels. Conclusion. A lower psychological distress score can result in better self-care, enhancing the probability of better HTN control; thus, psychological interventions may be necessary for the treatment of HTN. However, more studies are needed to assess the effectiveness of this intervention.

Endothelial MicroRNA-483-3p Is Hypertension-Protective

Hypertension is a high-risk factor for developing coronary heart disease and stroke. Endothelial dysfunction and arterial remodeling can lead to increased vascular wall thickness and arterial stiffness. Previous studies showed that microRNA-483 (miR-483) enhances endothelial cell (EC) function. Here, we investigated the protective role of miR-483 in hypertension. Data collected from two patient cohorts showed that the serum miR-483-3p level was associated with the progression of hypertension and positively correlated with vascular function. In cultured ECs, miR-483 targets a number of endothelial dysfunction-related genes, such as transforming growth factor-β (TGF-β), connective tissue growth factor (CTGF), angiotensin-converting enzyme 1 (ACE1), and endothelin-1 (ET-1). Overexpression of miR-483-3p in ECs inhibited Ang II-induced endothelial dysfunction, revealed by the decreased expression of TGF-β, CTGF, ACE1, and ET-1. Furthermore, miR-483-3p secreted from ECs was taken up by smooth muscle cells (SMCs) via the exosome pathway, which also decreased these genes in SMCs. Additionally, telmisartan could increase the aortic and serum levels of miR-483-3p in hypertension patients and spontaneous hypertension rats (SHR). These findings suggest that miR-483-3p exerts a protective effect on EC function during the onset of hypertension and thus may be considered a potential therapeutic target for hypertension-related cardiovascular diseases.

Development, feasibility, acceptability and preliminary evaluation of the internet and mobile phone-based BSHAPE intervention for Immigrant survivors of cumulative trauma

BACKGROUND

Cumulative trauma exposures can have a profound effect on women's health and well-being. Black immigrant women are disproportionately affected by cumulative trauma experiences that place them at risk for multiple health issues such as reproductive sexual health problems and HIV, or mental health problems such as PTSD. The trauma-informed internet and mobile phone-based Being Safe, Healthy, and Positively Empowered (BSHAPE) intervention was designed to comprehensively assess for cumulative traumatic experiences, for current safety, and to address women's co-occurring healthcare needs through educational, psychoeducational, and mindfulness-based stress-reduction components.

PURPOSE

This paper describes the development, feasibility, acceptability, and preliminary evaluation of the computer and phone delivered BSHAPE intervention among adult Black immigrant women survivors of cumulative trauma.

METHOD

Seventy women participated in the feasibility, acceptability, and preliminary evaluation of BSHAPE, with outcomes assessed at post-intervention. The feasibility and acceptability outcomes assessed were enrollment, adherence, and perceptions of the intervention. Preliminary evaluation outcomes included perceived stress, stress management, trauma coping self-efficacy, mindfulness, mental health (MH), HIV/STI risk, general empowerment, and empowerment related to safety.

CONCLUSIONS

Findings suggest that a BSHAPE intervention is feasible and acceptable. Overall, women reported satisfaction with BSHAPE and provided suggestions for improvement. Women showed significant reduction in perceptions of stress, improved stress-management, enhanced self-efficacy, reduced HIV/STI risk, and improved MH, overall empowerment, as well as empowerment related to safety. The findings of this study will be useful in further refining BSHAPE and testing it in a full-scale randomized controlled trial.
