The Relationship Among Health Beliefs, Depressive Symptoms, Medication Adherence, and Social Support in African Americans With Hypertension

Role of Perceived Social Support in Adherence to Antihypertensives and Controlled Hypertension: Findings of a Community Survey from Urban Nepal

Introduction

Social support is considered vital for effective management of chronic conditions, but its role in improving adherence to antihypertensive medication and control of hypertension in urban Nepal is unknown. We examined the role of social support in adherence to antihypertensives and controlled blood pressure to inform future interventions for hypertension management.

Methods

We analyzed cross-sectional data collected at baseline of a cluster randomized trial of hypertension patients (n=1252) in the community between May and November 2022. Multidimensional scale of perceived social support was used to measure social support, adherence to antihypertensives was measured using the Morisky medication adherence scale -8, and individuals with systolic- and diastolic- blood pressure less than 140 and 90 mmHg respectively were considered to have controlled hypertension. Modified Poisson regression models were used to estimate the prevalence ratios and corresponding 95% confidence intervals.

Results

We found that 914 (73%) individuals received moderate to high social support. Participants receiving high social support had a numerically lower proportion of controlled hypertension (51%) however not statistically significant. The proportion of good adherence to antihypertensives did not differ between the social support categories. There was no association in overall, family, friends, and significant other sub-scales of social support with controlled hypertension and adherence to antihypertensives.

Discussion

Further studies to understand the quality and mechanisms through which social support contributes to blood pressure control are needed for the health system to include social support in designing and implementing community-based interventions for hypertension management.

Unveiling the Nexus: Depressive Symptoms and Medication Adherence in Hypertensive Patients' Self-care: A Systematic Review

Background

Hypertension, a significant public health concern, is frequently linked to emotional disorders like depression. Research shows a reciprocal link between depression and hypertension, potentially influencing patients' adherence to self-care routines.

Objective

This systematic review aimed to examine the association between depressive symptoms and aspects of self-care, with a focus on medication adherence in individuals diagnosed with hypertension.

Methods

Following PRISMA guidelines, a systematic review was conducted by searching PubMed, PsycINFO and Scopus until March 17, 2023. The included studies involved quantitative primary research conducted in English, focusing on adults (≥18 years) diagnosed with hypertension and experiencing depressive symptoms. Observational studies were assessed using the Newcastle-Ottawa Scale, and randomized controlled trials were evaluated using the revised Cochrane Risk of Bias Tool (RoB 2.0). Due to the great diversity of these studies, a narrative synthesis of the results was undertaken. Results: A total of 18 studies involving 6,131 people with hypertension, that met our eligibility criteria were ultimately included. The reported rates of depressive symptoms ranged from 4% to 43%. Of these studies, nine reported a statistically significant association, showcasing an adverse impact of depressive symptoms on medication adherence. The remaining nine did not confirm the above.

Conclusion

This systematic review highlights the diverse body of research exploring depressive symptoms and medication adherence among individuals with hypertension. The review suggests a need for increased attention to self-care practices, particularly in relation to adherence to antihypertensive medication. However, it recommends the conduction of more robust longitudinal studies to comprehensively explore this relationship.

Association between depression and stroke and the role of sociodemographic factors: A study among hypertensive populations

OBJECTIVES

Studies have shown that depression increases the risk of stroke, and that this relationship can be modified by sex. However, few studies have explored this relationship in a hypertensive population, and an examination of sociodemographic factors may be useful in determining whether depression and stroke are related.

MATERIALS AND METHODS

We used data from the National Health and Nutrition Examination Survey conducted between 2005-2018. The relationship between depression and stroke was investigated using a multivariate logistic regression. Effect modification by sex was examined using an interaction analysis model.

RESULTS

Participants with mild or moderate depression had a 53 % (odds ratio, [OR] 1.53; 95 % confidence interval [CI], 1.15-2.04) higher risk of stroke than those without depression, with 1.76 times (95 % CI, 1.14-2.72) greater risk for major depression. Interaction analysis indicated that sex had no effect on this relationship (OR, 1.30; 95 % CI, 0.85-1.47, P=0.430). In comparison with Hispanics, non-Hispanic blacks and others/mixed-race individuals with depression had a greater risk of stroke (OR, 2.26; 95 % CI, 1.5-3.14; OR, 2.67, 95 % CI, 1.29-5.55).

CONCLUSIONS

Our study found that the degree of depression was positively correlated with stroke in a hypertensive population, and that this relationship was not affected by sex.

Validation and adaption of an Information-Motivation-Behavioral Skills model of medication adherence in older patients with multimorbidity

OBJECTIVE

To test and adapt the Information-Motivation-Behavioral Skills (IMB) model in explaining medication adherence for older patients with multimorbidity.

METHODS

Older patients with at least three chronic conditions (N = 254) were recruited from community health centers in Changsha, China. All participants completed a self-administrated questionnaire assessing adherence information, personal motivation, social motivation, behavioral skills, medication adherence, depressive symptoms, medication treatment satisfaction, treatment burden, and disease burden. Structural equation modeling was used to examine the hypothesized models and relationships between variables.

RESULTS

The final extended IMB model could explain 52.0% of the variance in adherence. Personal motivation (β = 0.29, p < 0.001), behavioral skills (β = 0.36, p < 0.001), and medication treatment satisfaction (β = 0.23, p = 0.001) had a positive direct effect on adherence. Information, social motivation, personal motivation, medication treatment satisfaction, and treatment burden could also affect adherence indirectly through multiple pathways.

CONCLUSION

This study demonstrated that an extended IMB model could be used to conceptualize determinants of medication adherence among older patients with multimorbidity.

PRACTICAL IMPLICATIONS

Adherence improvement programs might be more effective if targeting psychosocial factors, including adherence information, motivation, behavioral skills, treatment burden, and medication treatment satisfaction.

Prehospital Care of Coronary Artery Disease and Its Major Risk Factors in Geropsychiatric Inpatients

BACKGROUND

Older adults with serious mental illness have a high prevalence of coronary artery and its major risk factors, that is, arterial hypertension, dyslipidemia, and diabetes mellitus. The prevalence and clinical control of these conditions have not been compared in geropsychiatric inpatients with dementia versus those with mood or psychotic disorders.

STUDY QUESTION

What is the prevalence and acuity of coronary artery disease arterial hypertension, dyslipidemia, and diabetes mellitus among patients with dementia, mood, and psychotic disorders admitted for geropsychiatric care?

STUDY DESIGN

Patients 65 years of age or older were identified in a cohort of 1000 patients consecutively admitted over a 3-year period to the geropsychiatric unit of a 200-bed mental health hospital in suburban New York. All patients had a structured clinical and laboratory evaluation within 72 hours of admission.

DATA SOURCES

Primary psychiatric diagnoses, medical history, the frequency of poorly controlled cardiometabolic comorbidity, that is, requiring an immediate change in the management plan, and the Charlson Comorbidity Index.

RESULTS

The 65 years and older patient sample (N = 689) had a mean age of 74.8 years, and 58.8% of the subjects were women. The 205 patients with dementia were older (P < 0.001). Then, the 337 patients were with mood disorders and the 147 patients with psychotic. The numbers of medical conditions and Charlson Comorbidity Index after exclusion of dementia were similar in patients with dementia versus patients without dementia. A substantial number of patients had poorly controlled arterial hypertension (51.2%), dyslipidemia (25.4%), diabetes (24.2%), and coronary artery disease (15.4%). Patients with dementia had a lower prevalence of poorly controlled dyslipidemia (P = 0.0006), diabetes (P = 0.0089), and coronary artery disease (P = 0.045).

CONCLUSIONS

Compared with mood or psychotic disorder, a diagnosis of dementia with behavioral disturbance seemed to be associated with better control of coronary artery disease, dyslipidemia, and diabetes mellitus in geropsychiatric inpatients.

Challenges to dietary hypertension self-management as described by a sample of African American older adults

BACKGROUND

Hypertension rates are disproportionately higher among Black or African Americans (Black/African American) compared to other racial and ethnic groups in the United States. However, research on self-management strategies to control hypertension through healthy eating such as the Dietary Approaches to Stop Hypertension (DASH), and ketogenic diets has underexplored the use of dietary strategies among older Black/African American adults. In reporting contemporary challenges with implementing dietary strategies targeting blood pressure control among Black/African American older adults living with hypertension, this study addresses a clear need.

AIMS

Prior research has only partially addressed the challenges older Black/African Americans face in implementing and maintaining dietary strategies to control hypertension, therefore the current study aimed to address this gap by reporting contemporary challenges, as reported by a sample of Black/African American older adults living with hypertension.

METHODS

Nineteen Black/African American older adults living with hypertension participated in a focus group. An interview guide with open-ended questions on dietary approaches to self-management hypertension was used to guide data collection. Responses were audio-recorded, transcribed verbatim, and interpreted using qualitative thematic analysis.

RESULTS

Study participants were 71.6 years (SD = 8.3), 87.1% were women, and all were self-identified as Black/African American. Overall, participants shared that they were interested in improving their hypertension self-management skills. They expressed uncertainty about dietary strategies related in part to a lack of knowledge about incorporating or excluding certain foods and adhering to complex dietary recommendations. Participants also related financial concerns about accessing the recommended foods to control hypertension and expressed confusion about how to manage hypertension alongside other comorbidities.

LINKING EVIDENCE TO ACTION

This study highlights several barriers that Black/African American older adults face (lack of dietary knowledge, lack of financial resources, and unique barriers to managing multiple comorbid health conditions), which often pose simultaneous and intersecting barriers to managing hypertension using existing evidence-based dietary strategies.

Medication Adherence and Perceived Social Support of Hypertensive Patients in China: A Community-Based Survey Study

PURPOSE

Previous studies suggested perceived social support has impact on medication adherence among hypertensive patients, but did not simultaneously elucidate the different contents or key providers of social support that patients perceived. This study was to identify the contents and providers of perceived social support beneficial for improving medication adherence among hypertensive patients in China, which could prove important for targeted interventions.

PATIENTS AND METHODS

Following a multi-stage stratified sampling framework, a total of 903 hypertensive patients from 12 primary health institutions across a middle-income city were recruited from April to June 2021. Medication adherence was measured using the Chinese version of the Morisky, Green and Levine scale; perceived social support was determined using the name generator method. A binary logistic regression model was performed to identify the association between medication adherence and perceived social support. The contents of support included informational, emotional, and instrumental support (finances and caregiving). The support providers included spouse/partner, children, parents, siblings, other relatives, and friends.

RESULTS

A total of 506 (56.04%) patients optimally adhered to their antihypertensive medication. Female, older, urban patients, patients with shorter duration of hypertension and antihypertensive medications used showed better adherence (P<0.05). Optimal medication adherence was positively associated with the overall score of caregiving support (adjusted odds ratio [AOR] = 1.128; 95% confidence interval [CI] = [1.013-1.257]), informational support from the spouse/partner (AOR = 1.574; 95% CI = [1.112-2.227]), emotional support from the spouse/partner (AOR = 1.430; 95% CI = [1.032-1.981]), financial support from the spouse/partner (AOR = 1.439; 95% CI = [1.069-1.937]) and caregiving support from the spouse/partner (AOR = 1.652; 95% CI = [1.130-2.414]), whereas optimal medication adherence was negatively associated with caregiving support from friends (AOR = 0.499; 95% CI = [0.286-0.872]).

CONCLUSION

Informational, emotional, financial and caregiving support from spouses/partners have positive impacts on optimal medication adherence of hypertensive patients of community-level. Community-based interventions designed to improve medication adherence of hypertensive patients should target both patients and their spouses/partners; spouses/partners could be encouraged to provide various support to improve the medication adherence of hypertensive patients.

Sociodemographic moderation of the association between depression and stroke incidence in a retrospective cohort of 0.4 million primary care recipients with hypertension

BACKGROUND

Previous research has suggested an association between depression and subsequent acute stroke incidence, but few studies have examined any effect modification by sociodemographic factors. In addition, no studies have investigated this association among primary care recipients with hypertension.

METHODS

We examined the anonymized records of all public general outpatient visits by patients aged 45+ during January 2007-December 2010 in Hong Kong to extract primary care patients with hypertension for analysis. We took the last consultation date as the baseline and followed them up for 4 years (until 2011-2014) to observe any subsequent acute hospitalization due to stroke. Mixed-effects Cox models (random intercept across 74 included clinics) were implemented to examine the association between depression (ICPC diagnosis or anti-depressant prescription) at baseline and the hazard of acute stroke (ICD-9: 430-437.9). Effect modification by age, sex, and recipient status of social security assistance was examined in extended models with respective interaction terms specified.

RESULTS

In total, 396 858 eligible patients were included, with 9099 (2.3%) having depression, and 10 851 (2.7%) eventually hospitalized for stroke. From the adjusted analysis, baseline depression was associated with a 17% increased hazard of acute stroke hospitalization [95% confidence interval (CI) 1.03-1.32]. This association was suggested to be even stronger among men than among women (hazard ratio = 1.29, 95% CI 1.00-1.67).

CONCLUSION

Depression is more strongly associated with acute stroke incidence among male than female primary care patients with hypertension. More integrated services are warranted to address their needs.

Social Support and Self-Efficacy as Mediating Factors Affecting the Association Between Depression and Medication Adherence in Older Patients with Coronary Heart Disease: A Multiple Mediator Model with a Cross-Sectional Study

PURPOSE

Medication non-adherence is a major public health issue. Recent evidence suggests that depression, inadequate social support, and lower levels of self-efficacy are associated with poor medication adherence. However, the mechanism underlying the association among depression, social support, self-efficacy and medication adherence is unclear. This study aims to examine the mediating role of social support and self-efficacy between depression and medication adherence in older patients with coronary heart disease.

PATIENTS AND METHODS

Data were collected from 238 hospitalized older patients with coronary heart disease. Depression, social support, self-efficacy, and medication adherence were assessed using structured questionnaires. A serial multiple mediation model was tested using the PROCESS macro for SPSS.

RESULTS

A total of 238 older patients with CHD with a mean age of 70.5 years were involved in this cross-sectional study. Depression was negatively correlated with medication adherence in older patients with coronary heart disease. Social support and self-efficacy were positively associated with medication adherence, and fully mediated the relationship between depression and medication adherence. Three mediation paths were included in the model: (a) social support, (b) chain combination of social support and self-efficacy, and (c) self-efficacy.

CONCLUSION

Social support and self-efficacy explain the association of depression and medication adherence in older CHD patients and may be the keys target for enhanced intervention to improve medication adherence in older CHD patients with depression.

A predictive model for identifying low medication adherence among older adults with hypertension: A classification and regression tree model

Various individual characteristics may affect medication adherence; however, few studies have investigated the effect of interrelationships among these various individual characteristics on medication adherence. This cross-sectional study explored the interrelationships among risk factors for medication adherence and established a predictive model of low medication adherence among older adults with hypertension. Convenience sampling was used to recruit 300 older adults with hypertension. The following parameters were recorded: demographic and disease characteristics, health beliefs, self-efficacy, social support, and medication adherence of antihypertensive drugs. Classification and regression tree (CART) analysis was performed to develop a predictive model of low medication adherence. The CART model revealed that health belief, disease duration, self-efficacy, and social support interacted to contribute to various pathways of low medication adherence. The predicted accuracy of the model was validated with a low misclassification rate of 26%. The proposed classification model can help identify risk cases with low medication adherence. Suitable health education programs based on these risk factors to manage and improve medication adherence for older adults with hypertension could be considered.

The association between social support and medication adherence in patients with hypertension: A systematic review

Background:

Medication adherence is a primary determinant of treatment success in hypertensive patients. One of the challenges for healthcare providers that has received little attention is the impact of patients’ social supports on medication adherence.

Objective:

This review evaluates the impact of patients’ social supports on medication adherence in hypertensive patients.

Methods:

A systematic review methodology was used. Pubmed, CINAHL, Embase, and PsycINFO databases were searched systematically for relevant articles. The outcome measure in the studies was medication adherence in hypertension.

Results:

From 1155 articles, 238 were retained for further assessment, and finally, 14 met the inclusion criteria. Statistically significant positive associations between medication adherence and social support were found in nine studies (p<0.05).

Conclusions:

This review evaluated the impact of social support on medication adherence and highlighted gaps in the literature regarding the impact of social support on adherence. Family members or peer support may promote better adherence in some patient groups. This review suggests that healthcare providers may need to consider whether patients have appropriate social supports in place which will assist them adhering to and benefiting from treatment recommendations.

The Effect of Contextualized Racial and Gendered Stressors, Social Support, and Depression on Hypertension Illness Perceptions and Hypertension Medication Adherence in Young African American Women With Hypertension

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 (β = 0.22, P < .01) and depressive symptoms (β = 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.

Investigating Relationships Between Hypertension, Sleep, and Cognitive Risk in an Underserved Community

Purpose

The aim of this descriptive correlational pilot study was to investigate the relationship between hypertension, sleep deprivation, and risk of Alzheimer's disease in a rural, older, underserved, and ethnically diverse cohort.

Sample

Residents (n = 52) from three independent subsidized housing units for retired farmer workers, located in a rural Florida area known as the Glades, volunteered for the study.

Methods

A quantitative descriptive approach using Pearson correlations, t-tests, and scatter plot analysis was applied to surveys and Mini-CogTM results.

Findings

About a quarter (23.1%) of the participants were identified as being at risk for cognitive impairment. Hypertension risk correlated moderately with cognitive impairment risk (r = 0.40, p = 0.01). However, in this ethnically, diverse cohort, sleep quality did not significantly influence either blood pressure or cognitive status. This is contrary to other studies that have found an increased risk of Alzheimer's disease among persons with hypertension (Carnevale, Perrotta, Lembo, & Trimarco, 2015) and insufficient sleep (Brzecka et al., 2018).

Implications

These results suggest that further investigation is needed to examine if rural living or culture moderates Alzheimer's disease risk factors of diminished sleep and hypertension. Future findings could impact the design of interventions aimed at reducing AD risk in diverse rural settings.

Self-care research: Where are we now? Where are we going?

BACKGROUND AND OBJECTIVE

The beneficial effects of self-care include improved well-being and lower morbidity, mortality, and healthcare costs. In this article we address the current state of self-care research and propose an agenda for future research based on the inaugural conference of the International Center for Self-Care Research held in Rome, Italy in June 2019. The vision of this Center is a world where self-care is prioritized by individuals, families, and communities and is the first line of approach in every health care encounter. The mission of the Center is to lead the self-care research endeavor, improving conceptual clarity and promoting interdisciplinary work informed by a shared vision addressing knowledge gaps. A focused research agenda can deepen our theoretical understanding of self-care and the mechanisms underlying self-care, which can contribute to the development of effective interventions that improve outcomes.

METHODS

During conference discussions, we identified seven major reasons why self-care is challenging, which can be grouped into the general categories of behavior change and illness related factors. We identified six specific knowledge gaps that, if addressed, may help to address these challenges: the influence of habit formation on behavior change, resilience in the face of stressful life events that interfere with self-care, the influence of culture on self-care behavioral choices, the difficulty performing self-care with multiple chronic conditions, self-care in persons with severe mental illness, and the influence of others (care partners, family, peer supporters, and healthcare professionals) on self-care.

PLANS TO ACHIEVE RESULTS

To achieve the vision and mission of the Center, we will lead a collaborative program of research that addresses self-care knowledge gaps and improves outcomes, create a supportive international network for knowledge transfer and support of innovations in self-care research, and support and train others in self-care research. Beyond these specific short-term goals, important policy implications of this work are discussed.
