mHealth Intervention for Promoting Hypertension Self-management Among African American Patients Receiving Care at a Community Health Center: Formative Evaluation of the FAITH! Hypertension App

BACKGROUND

African American individuals are at a higher risk of premature death from cardiovascular diseases than White American individuals, with disproportionate attributable risk from uncontrolled hypertension. Given their high use among African American individuals, mobile technologies, including smartphones, show promise in increasing reliable health information access. Culturally tailored mobile health (mHealth) interventions may promote hypertension self-management among this population.

OBJECTIVE

This formative study aimed to assess the feasibility of integrating an innovative mHealth intervention into clinical and community settings to improve blood pressure (BP) control among African American patients.

METHODS

A mixed methods study of African American patients with uncontrolled hypertension was conducted over 2 consecutive phases. In phase 1, patients and clinicians from 2 federally qualified health centers (FQHCs) in the Minneapolis-St Paul, Minnesota area, provided input through focus groups to refine an existing culturally tailored mHealth app (Fostering African-American Improvement in Total Health! [FAITH!] App) for promoting hypertension self-management among African American patients with uncontrolled hypertension (renamed as FAITH! Hypertension App). Phase 2 was a single-arm pre-post intervention pilot study assessing feasibility and patient satisfaction. Patients receiving care at an FQHC participated in a 10-week intervention using the FAITH! Hypertension App synchronized with a wireless BP monitor and community health worker (CHW) support to address social determinants of health-related social needs. The multimedia app consisted of a 10-module educational series focused on hypertension and cardiovascular risk factors with interactive self-assessments, medication and BP self-monitoring, and social networking. Primary outcomes were feasibility (app engagement and satisfaction) and preliminary efficacy (change in BP) at an immediate postintervention assessment.

RESULTS

In phase 1, thirteen African American patients (n=9, 69% aged ≥50 years and n=10, 77% women) and 16 clinicians (n=11, 69% aged ≥50 years; n=14, 88% women; and n=10, 63% African American) participated in focus groups. Their feedback informed app modifications, including the addition of BP and medication tracking, BP self-care task reminders, and culturally sensitive contexts. In phase 2, sixteen African American patients were enrolled (mean age 52.6, SD 12.3 years; 12/16, 75% women). Overall, 38% (6/16) completed ≥50% of the 10 education modules, and 44% (7/16) completed the postintervention assessment. These patients rated the intervention a 9 (out of 10) on its helpfulness in hypertension self-management. Qualitative data revealed that they viewed the app as user-friendly, engaging, and informative, and CHWs were perceived as providing accountability and support. The mean systolic and diastolic BPs of the 7 patients decreased by 6.5 mm Hg (P=.15) and 2.8 mm Hg (P=.78), respectively, at the immediate postintervention assessment.

CONCLUSIONS

A culturally tailored mHealth app reinforced by CHW support may improve hypertension self-management among underresourced African American individuals receiving care at FQHCs. A future randomized efficacy trial of this intervention is warranted.

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.

Knowledge as a Factor Associated with Lifestyle in Controlling Hypertension

Hypertension is also understood as the "silent killer" as the symptoms of hypertension are frequently not experienced by the sufferer, hence, the majority of hypertension patients are unaware that they suffer from hypertension. Uncontrolled hypertension can harm multiple organs. Hypertension cannot be cured; however, it can be managed such that blood pressure stays within normal limits. Changes in lifestyle and pharmacological therapy are employed to control hypertension. The objective of this study is to investigate the association between hypertension patients' characteristics and amount of awareness about lifestyle in controlling hypertension. A descriptive analytic design with a cross sectional approach was administered in this investigation. This study included all hypertension patients who visited the Cibubur Village Health Center. Purposive sampling was utilized in this study, yielding 115 respondents. The analysis technique involved the Chi-Square test. Results: There was a relationship between age and lifestyle (p=0.044), the last education and lifestyle (p = 0.017), and the level of knowledge with lifestyle (p=0.000). Meanwhile, gender, occupation, and family history of hypertension did not possess a significant relationship with lifestyle in controlling hypertension. Future studies are suggested to examine the role of external environmental support in influencing lifestyle to control hypertension.

Psychometric properties and validation of the revised Chinese Medication Literacy Scale for Hypertensive Patients (C-MLSHP-R)

Background

Medication literacy is one of the key indicators that can affect the self-management of medications and medication safety. This study aimed to revise the Chinese Medication Literacy Scale for hypertensive patients (C-MLSHP) and test the reliability and validity of the revised scale.

Methods

We revised the C-MLSHP by several methods, i.e., focus group discussion, expert consultation, patient interview, and pilot study, based on the established evaluation index system of medication literacy for hypertensive patients. Then, a formal survey using the revised Chinese Medication Literacy Scale for hypertensive patients (C-MLSHP-R) was carried out on hypertensive patients from hospitals and community healthcare centers in Changsha city of China to test its reliability and validity. The reliability was evaluated with Cronbach's α coefficient, split-half reliability, and test–retest reliability. The validity was evaluated with content validity, construct validity, convergent validity, discriminant validity, and criterion-related validity.

Results

The C-MLSHP-R contained 18 items within four domains, i.e., the knowledge domain included four items, the attitude domain had three items, the skill domain involved seven items, and the practice domain included four items. A total of 339 hypertensive patients participated in the formal survey. The results showed that the Cronbach's α coefficient of C-MLSHP-R was 0.802, and for each domain ranged from 0.639 to 0.815. The split-half reliability coefficient of C-MLSHP-R was 0.709, and for each domain ranged from 0.648 to 0.792. The test–retest reliability coefficient of C-MLSHP-R was 0.851, and for each domain ranged from 0.655 to 0.857. The I-CVI of each item ranged from 0.833 to 1.000, the S-CVI/Ave of C-MLSHP-R was 0.981, the S-CVI/UA was 0.889, and for each domain ranged from 0.958 to 1.000. Confirmatory factor analysis results showed that the model fitted well. The convergent validity of C-MLSHP-R was acceptable, and the discriminant validity was good. The criterion coefficient between C-MLSHP-R and C-MLSHP was 0.797, and for each domain ranged from 0.609 to 0.755.

Conclusion

Compared with C-MLSHP, the C-MLSHP-R with 18 items was much shorter for measuring, and had decreased reliability within the acceptable range and better validity, which was more appropriate and time-saving to assess the medication literacy level for hypertensive patients scientifically and conveniently.

Behavioral Factors Associated with Medication Nonadherence in Patients with Hypertension

Medication nonadherence is associated with an increased risk of complications in hypertensive patients. We investigated behavioral factors associated with medication nonadherence in hypertensive patients in southern Taiwan. Using questionnaires, we collected data regarding clinicodemographic characteristics and nonadherence behaviors from 238 hypertensive patients. We assessed the self-reported prevalence of specific behaviors of medication nonadherence and investigated factors associated with each behavior using multivariable logistic regression analysis. The most common behavior of medication nonadherence was forgetting to take medication (28.6%), followed by discontinuing medication (9.2%) and reducing the medication dose (8.8%). Age ≥ 65 years (adjusted odds ratio [aOR] = 0.32, 95% confidence interval [CI] = 0.15–0.69) and male sex (aOR = 2.61, CI = 1.31–5.19) were associated with forgetting to take medication. The presence of comorbidities (diabetes, kidney disease, or both) and insomnia (aOR = 3.97, 95% CI = 1.30–12.1) was associated with reducing the medication dose. The use of diet supplements was associated with discontinuing the medication (aOR = 4.82, 95% CI = 1.50–15.5). Compliance with a low oil/sugar/sodium diet was a protective factor against discontinuing medication (aOR = 0.14; 95% CI = 0.03–0.75). The most pervasive behavior associated with medication nonadherence among hypertensive patients was forgetting to take medication. Age <65 years, male sex, comorbidities, insomnia, noncompliance with diet, and the use of dietary supplements were specifically associated with medication nonadherence.

Adherence to lifestyle modifications and its associated factors in hypertensive patients

AIMS AND OBJECTIVES

To find out the adherence to lifestyle modifications and its associated factors in hypertensive patients.

BACKGROUND

Low adherence to lifestyle modifications leads to poor therapeutic effectiveness, decreased quality of life, poor health outcomes and increased health care costs. Various factors play an important role in determining the adherence level varying among the different cultural, social and national contexts.

DESIGN

A cross-sectional analytical research design was carried out.

METHODS

Information from 264 patients with hypertension was collected at the Outpatient Department of Manmohan Cardiothoracic, Vascular and Transplant Center, Kathmandu. A standard tool of WHO Steps Survey Questionnaire and Hypertension Fact Questionnaire was used for data collection. Chi-square test and binary logistic regression were used for analysis using SPSS 16.

RESULT

The overall adherence to lifestyle modifications was determined as 20.8% with the adherence rate being lowest up to 30.3% for adequate intake of fruits and vegetables. Likewise, 52.5% of patients had average knowledge of hypertension management. Age (p = .021), education (p = .001), occupation(p = .026), household income (p = .007) and family history(p = .011) had statistically significant association with the level of adherence. Younger age (AOR = 1.85 CI = 0.79-4.33) remained as the independent predictor of high adherence to lifestyle modifications. The study followed the STROBE checklist for reporting cross-sectional study.

CONCLUSION

This study identified that adherence to lifestyle modification is low in older patients. More effective lifestyle modification counselling and educational approaches focusing on the older age groups as well as considering educational level, occupation, family income and family history of hypertension are required to improve their level of adherence.

RELEVANCE TO CLINICAL PRACTICE

Nurses are frequently acquainted with the hypertensive patients in hospitals where they need to provide health teaching on lifestyle modifications. This study identifies the factors that need to be considered while counselling the hypertensive patients.

Our Whole Lives for Hypertension and Cardiac Risk Factors (OWL-H)—Combining a Teaching Kitchen Group Visit with an Online Platform: A Feasibility Trial (Preprint)

Background

Hypertension (HTN) affects millions of Americans. Our Whole Lives: an eHealth toolkit for Hypertension and Cardiac Risk Factors (OWL-H) is an eHealth platform that teaches evidence-based lifestyle strategies, such mindfulness and cooking skills, to improve self-management of HTN.

Objective

The primary goal of this pilot study was to evaluate the feasibility of OWL-H combined with teaching kitchen medical group visits (TKMGVs) in a low-income population of participants with HTN.

Methods

We conducted a pre-post 8-week study to assess the feasibility of a hybrid program (a web-based 9-module self-management program, which includes mindfulness and Mediterranean and Dietary Approaches to Stop Hypertension diet) accompanied by 3 in-person TKMGVs among patients with HTN. Data including demographics, platform use, and satisfaction after using OWL-H were examined. Outcome data collected at baseline and 8 weeks included the Mediterranean Diet Questionnaire, Hypertension Self-Care Profile Self-Efficacy Instrument, Blood Pressure Knowledge Questionnaire, and the number of self-reported blood pressure readings. For the statistical analysis, we used descriptive statistics, paired sample t tests (1-tailed), and qualitative methods.

Results

Of the 25 enrolled participants, 22 (88%) participants completed the study. Participants’ average age was 57 (SD 12.1) years, and 46% (11/24) of them reported a household income <US $30,000 per year. Among the 22 participants who logged in to OWL-H, the average number of mindfulness practices completed was 7 and the average number of module sessions accessed was 4. In all, 73% (16/22) of participants reported that they were “very satisfied” with using OWL-H to help manage their HTN. Participants’ blood pressure knowledge significantly increased from baseline (mean 5.58, SD 1.44) to follow-up (mean 6.13, SD 1.23; P=.03). Participants significantly increased their adherence to a Mediterranean diet from baseline (mean 7.65, SD 2.19) to follow-up (mean 9, SD 1.68; P=.004). Participants’ self-efficacy in applying heart-healthy habits, as measured by the Hypertension Self-Care Profile Self-Efficacy Instrument, increased from baseline (mean 63.67, SD 9.06) to follow-up (mean 65.54, SD 7.56; P=.14). At the 8-week follow-up, 82% (18/22) of the participants had self-reported their blood pressure on the OWL-H platform at least once during the 8 weeks.

Conclusions

The eHealth platform for HTN self-management, OWL-H, and accompanying in-person TKMGVs have the potential to effectively improve lifestyle management of HTN.

Adherence to antihypertensive medications and associated factors among hypertensive patients in Ethiopia: Systematic review and meta-analysis

The foundation of controlling hypertension is adherence to antihypertensive medication adherence. This systematic review and meta-analysis aimed to assess the magnitude and associated factors of adherence to antihypertensive medication among adult hypertensive patients in Ethiopia. A comprehensible bibliographic searching was conducted from PubMed, EMBASE, Scopus, and Web of Science core collection. All published and unpublished studies that had been accessible before 31 May 2020, and written in English were eligible. Joanna Briggs Institute assessment tool was used to evaluate the quality of the findings of the included studies. Stata software 16.0 was used to analyze the data. Study-specific estimates were pooled to determine the overall prevalence estimate across studies using a random-effects meta-analysis model. Publication bias and heterogeneity were checked. Fourteen studies with a total of 4938 hypertensive patients were included in the final systematic review and meta-analysis. The pooled prevalence of medication adherence among hypertensive patients in Ethiopia was 65.41% (95% confidence interval: 58.91-71.91). Sub-group analysis shown that the pooled prevalence of medication adherence was the highest (69.07%, 95% confidence interval: 57.83-80.31, I ² = 93.51) among studies using questionnaire technique whereas the lowest in Morisky Medication Adherence Scale eight-items (60.66%, 95% confidence interval: 48.92-72.40, I ² = 97.16). Moreover, medication adherence was associated with the presence of comorbidities (pooled odds ratio = 0.23, 95% confidence interval: 0.07-0.38, p = 0.030, I ² = 54.9%) and knowledge about the disease and its management (pooled odds ratio = 2.98, 95% confidence interval: 1.72-4.24, p = 0.04, I ² = 55.55%) but not with place of residence (pooled odds ratio = 1.22, 95% confidence interval: 0.51-1.93, p = 0.00, I ² = 76.9%). Despite a lack of uniformity among included studies, adherence to antihypertensive medication among the hypertensive population in Ethiopia was moderate. The presence of comorbidities and/or complications reduced the odds of adherence whereas having good knowledge about the disease increased chance of medication adherence among hypertensive patients.

Adherence to Lifestyle Modifications and Associated Factors Among Adult Hypertensive Patients Attending Chronic Follow-Up Units of Dessie Referral Hospital, North East Ethiopia, 2020

Background

Hypertension is a major health problem throughout the world which affects over one billion people due to severe complications and inadequate control. Even though lifestyle modification is one of the most effective ways to prevent and control hypertension, only little emphasis has been given for it compared with treating hypertension with medication. Therefore, the aim of this study was to assess adherence to lifestyle modifications and associated factors among hypertensive patients attending Dessie referral hospital.

Materials and Methods

Institutional-based cross-sectional study design was conducted among 301 hypertensive patients during May and June, 2020. The study participants were selected with a convenient sampling technique due to the COVID-19 pandemic. Data were collected using pre-tested and structured face to face interviewer-administered questionnaire and checked, cleaned and entered into Epi data version 4.4 and exported to SPSS version 25.0 software for analysis. The associations between independent variables and dependent variable were analyzed using binary logistic regression models.

Results

A total of 301 respondents participated in the study yielding a response of 100%. The overall adherence in this study was only 23.6%. Independent predictors of adherence to lifestyle modifications were divorced (AOR=0.35; 95% CI (0.13–0.94)) and widowed (AOR=0.27; 95% CI (0.10–0.75)), secondary school education (AOR=4.85; 95% CI (1.54–15.22)), no regular income (AOR=0.22; 95% CI (0.08–0.65)) or monthly income of ≥3000 ETB (AOR=5.58; 95% CI (2.46–12.66)), having co-morbidities (AOR=2.37; CI (1.23–4.57)), good knowledge about the disease (AOR=1.83; CI (0.92–3.65)) and good self-efficacy (AOR=3.64; CI (1.75–7.55)).

Conclusion and Recommendations

The overall adherence to recommended lifestyle modifications was very low. The independent predictors were marital status, educational level, monthly income, having co-morbidities, knowledge and self-efficacy. Therefore, multifaceted and collaborative implementation of strategies about lifestyle modifications for hypertension prevention and control are needed to address barriers at the patient, provider, system and community levels.
