South Asians' experience of managing hypertension: a grounded theory study

Barriers and facilitators of lifestyle management among adult South Asian migrants living with chronic diseases: A mixed-methods systematic review

BACKGROUND AND AIM

South Asian migrants have a higher prevalence of chronic diseases than Caucasians. Despite much literature that has explored challenges in chronic disease management amongst the South Asian population in the past decades, their chronic disease management is still suboptimal. Understanding their determinants of disease management behaviour using the Theoretical Domains Framework will inform the development of a culturally sensitive intervention relevant to consumer-end-users. This study aimed to synthesise qualitative and quantitative studies on chronic disease management among adult South Asian immigrants.

METHODS

A mixed-methods systematic review was conducted using electronic databases. The Mixed Methods Appraisal Tool assessed the quality of the included studies. Quantitative data were transformed into qualitative data and analysed thematically. Subthemes were mapped in the Theoretical Domains Framework presenting barriers and facilitators under each theme.

RESULTS

18293 studies were identified, of which 37 studies were included. The barriers and facilitators identified were categorised into four overarching themes: patient-provider interaction and relationship (e.g., complex language use by health professionals), the impact of migration (e.g., weather conditions had an impact on engagement with physical activity), heritage-based practices (e.g., an obligation to consume energy-dense food in social gatherings), and chronic disease management strategies (e.g., lack understanding of appropriate disease management strategies).

CONCLUSION

This review provides a comprehensive understanding of the complexity of chronic disease management among South Asian migrants and insights into developing multifaceted interventions to address barriers to chronic disease management, guiding the healthcare professionals in helping overcome South Asians perceived barriers to managing chronic disease in the host countries.

Concordance between Dash Diet and Hypertension: Results from the Mediators of Atherosclerosis in South Asians Living in America (MASALA) Study

High blood pressure is an important predictor of atherosclerotic cardiovascular disease (ASCVD), particularly among South Asians, who are at higher risk for ASCVD when compared to other population groups. The Dietary Approaches to Stop Hypertension (DASH) dietary pattern is established as the best proven nonpharmacological approach to preventing hypertension in adults. Using data from the Mediators of Atherosclerosis in South Asians Living in America (MASALA) cohort, we calculated a DASH dietary score to examine the association between adherence to the DASH diet and its components, and prevalent and incident hypertension and systolic and diastolic blood pressure, after five years of follow-up. We found that the relative risk ratio (RRR) of incident hypertension was 67% lower among participants in the highest DASH diet score category (aRRR: 0.33; 95% CI: 0.13, 0.82; ptrend = 0.02) compared with those in the lowest DASH diet score category in fully adjusted models. These findings are consistent with previous clinical trials and large prospective cohort studies, adding to evidence that supports the diet-disease relationship established between DASH diet and hypertension. This study is the first to examine DASH diet adherence and hypertension among South Asian adults in the U.S.

Heightened risks of cardiovascular disease in South Asian populations: causes and consequences

INTRODUCTION

South Asian individuals comprise almost a quarter of the world's population and have an excess risk of atherosclerotic cardiovascular disease (ASCVD) compared to other ethnicities. In part, this can be explained by higher prevalence, earlier onset, and suboptimal control of traditional cardiovascular risk factors, such as insulin resistance, metabolic syndrome, and dyslipidaemia. However, there remains a significant residual excess risk associated with South Asian ethnicity after controlling for traditional risk factors.

AREAS COVERED

In this review, we describe the epidemiology of ASCVD in both native and diaspora South Asian populations. We explore how traditional cardiovascular risk factors, novel cardiovascular risk factors, and social determinants of health may contribute to the excess ASCVD risk seen in South Asian populations.

EXPERT OPINION

There should be increased awareness of the relative importance of South Asian ethnicity and related social determinants of health, as risk factors for ASCVD. Systematic screening processes should be tailored to this population, and modifiable risk factors should be treated aggressively. Further research is required to quantify determinants of the excess ASCVD risk seen in South Asian populations and to develop targeted interventions to address these factors.

Integrating Community Health Workers into Community-Based Primary Care Practice Settings to Improve Blood Pressure Control Among South Asian Immigrants in New York City: Results from a Randomized Control Trial

BACKGROUND

Blood pressure (BP) control is suboptimal in minority communities, including Asian populations. We evaluate the feasibility, adoption, and effectiveness of an integrated CHW-led health coaching and practice-level intervention to improve hypertension control among South Asian patients in New York City, Project IMPACT (Integrating Million Hearts for Provider and Community Transformation). The primary outcome was BP control, and secondary outcomes were systolic BP and diastolic BP at 6-month follow-up.

METHODS

A randomized-controlled trial took place within community-based primary care practices that primarily serve South Asian patients in New York City between 2017 and 2019. A total of 303 South Asian patients aged 18-85 with diagnosed hypertension and uncontrolled BP (systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg) within the previous 6 months at 14 clinic sites consented to participate. After completing 1 education session, individuals were randomized into treatment (n=159) or control (n=144) groups. Treatment participants received 4 additional group education sessions and individualized health coaching over a 6-month period. A mixed effect generalized linear model with a logit link function was used to assess intervention effectiveness for controlled hypertension (Yes/No), adjusting for practice level random effect, age, sex, baseline systolic BP, and days between BP measurements.

RESULTS

Among the total enrolled population, mean age was 56.8±11.2 years, and 54.1% were women. At 6 months among individuals with follow-up BP data (treatment, n=154; control, n=137), 68.2% of the treatment group and 41.6% of the control group had controlled BP (P<0.001). In final adjusted analysis, treatment group participants had 3.7 [95% CI, 2.1-6.5] times the odds of achieving BP control at follow-up compared with the control group.

CONCLUSIONS

A CHW-led health coaching intervention was effective in achieving BP control among South Asian Americans in New York City primary care practices. Findings can guide translation and dissemination of this model across other communities experiencing hypertension disparities.

Influence of “Hospital-Community-Family” Integrated Management on Blood Pressure, Quality of Life, Anxiety and Depression in Hypertensive Patients

Objective

To explore the Influence of “hospital-community-family” integrated management on blood pressure, quality of life, anxiety and depression in hypertensive patients.

Methods

A total of 60 patients with hypertension were treated in our hospital from July 2019 to July 2021. The patients were randomly divided into control group (n =30) and study group (n =30). The former accepts routine management, while the latter accepts “hospital-community-family” integrated management. Nursing satisfaction, blood pressure, disease awareness rate, anxiety and depression scores, disease control ability and quality of life scores were compared.

Results

First of all, we compared the nursing satisfaction: the study group was very satisfied in 25 cases, satisfactory in 4 cases, general in 1 case, the satisfaction rate was 100.00%, while in the control group, 10 cases were very satisfied, 8 cases were satisfied, 7 cases were general, and 5 cases were dissatisfied, the satisfaction rate was 83.33%; The nursing satisfaction of the study group was higher than that of the control group (P <0.05). Secondly, we compared the level of blood pressure. There was no significant difference before management (P >0.05) but the blood pressure decreased after treatment. In the control group, the level of blood pressure in the study group was lower than that in the control group (P <0.05). In terms of disease awareness rate the scores of hypertension related knowledge hypertension harmfulness community management methods regular reexamination and blood pressure monitoring in the study group were significantly higher than those in the control group (P <0.05). There was no significant difference in anxiety and depression scores before treatment (P >0.05), but decreased after treatment. Compared with the control group, the anxiety and depression scores of the study group were lower (P <0.05). In terms of disease control ability, the total scores of diet management, medication management, behavior management and information management in the study group were higher compared to the control group (P <0.05). Finally, we compared the scores of qualities of life. Before management, there exhibited no significant difference (P >0.05). After management, the scores of quality of life decreased. Compared to the control group, the scores of physiological function, psychological function, social function and health self-cognition in the study group were lower than those in control group (P <0.05).

Conclusion

The application of integrated “hospital, community and family” management can vertically integrate medical resources and establish a truly effective hierarchical treatment model. Integrated “hospital-community-family” management can improve patient compliance with treatment, enhance patients' self-management ability and confidence, and improve the management efficiency of medical staff.

Undiagnosed Hypertension in Vancouver's Punjabi Sikh Community: A Cross-Sectional Study

South Asians bear a greater burden of cardiovascular disease (CVD) compared to other ethnic groups and hypertension is a major modifiable risk factor. The purpose of this study was to examine rates and predictors of uncontrolled blood pressure among an immigrant Punjabi Sikh community in Vancouver. We recruited 350 adults (40% women; mean age 67.3 ± 11.9 years) across 5 Sikh temples and measured blood pressure, heart rate, height, weight, waist circumference, socio-demographic background, and health history. 42% of participants had uncontrolled blood pressure of which one-third reported no previous history of hypertension. Based on modified cut-offs for South Asians, the mean waist circumferences across groups were well above target and 50% classified as obese. A higher percentage in the uncontrolled group (vs. controlled group) were of an older age, had a diabetes history and reported a physically active lifestyle. Findings suggest more efforts are needed to reduce the rates of uncontrolled blood pressure in this community. Interventions such as blood pressure drives, community-based outreach programs, and physical activity and dietary interventions should be explored to lower this CVD risk factor in this community.

Assessment of health-related quality of life in hypertensive hemodialysis patients

BACKGROUND AND OBJECTIVES

Globally, the prevalence of hypertension (HTN) with the coexistence of chronic kidney disease (CKD) is increasing, resulting in poor quality of life. The main objective of the study was to measure the health-related quality of life (HRQoL) of hypertensive hemodialysis patients.

METHODS

A multicenter follow-up study was carried out in six public and two private dialysis centers in Pakistan. A total of 517 hypertensive hemodialysis patients responded by completing the questionnaire at baseline and two subsequent phases. The quality of life of these patients was assessed using the EQ-5D-5L questionnaire (a standardized instrument for measuring generic health status). Statistical analysis was done using a multivariate linear regression model, Friedman test and Kruskal Wallis test.

RESULTS

The majority of patients (58.2%) had normal body mass index and about 60.5% of the patients were taking less salt due to HTN. Friedman test gave the statistically significant results (p ≤ 0.001) in systolic blood pressure (BP), diastolic BP and EQ-5D visual analogue scale (VAS) score between three phases (initial visit, first follow-up and second follow-up). A significant improvement was observed in self-care and usual activities from initial visit to first follow-up (p < 0.05). The most problematic dimension among the hypertensive patients with CKD was pain/discomfort (86.5%).

CONCLUSIONS

HTN with coexisting CKD in hemodialysis patients severely affected HRQoL. Pain/discomfort was the most problematic dimension among the participants.

Hypertension in Women: A South-Asian Perspective

Introduction

Hypertension is an important contributor to cardiovascular disease related morbidity and mortality. Despite the magnitude of its negative impact on cardiovascular outcomes, treatment and control of hypertension remain suboptimal in both men and women.

Materials and Methods

Numerous databases, i.e., PubMed, ScienceDirect, etc., were searched using keywords to identify relevant studies to our narrative review. The findings from the most pertinent articles were summarized and integrated into our narrative review on hypertension in women.

Results

The pathophysiology of essential hypertension is still being delineated in both men and women; there are multiple sex specific factors in association with the development of hypertension in women, including age, combined oral contraceptives (COCs), polycystic ovarian syndrome (PCOS), preeclampsia, etc. There are several sex specific considerations in antihypertensives drug choices.

Discussion

Despite the magnitude of its negative impact on cardiovascular outcomes, treatment and control of hypertension remain suboptimal in women. Medical treatment and adherence is uniquely challenging for South Asian women due to a variety of socio-cultural-economic factors. Further research is warranted to identify optimal sex-specific treatment options that will improve the control of hypertension and decrease the risk of subsequent cardiovascular disease in both genders.

Development of a multimedia intervention to improve pneumoconiosis prevention in construction workers using RE-AIM framework

Pneumoconiosis is a common occupational lung disease among construction workers. Educational interventions targeting specific ethnic groups of construction workers are of benefit for pneumoconiosis prevention. The aim of this study was to develop a multimedia educational intervention for pneumoconiosis prevention for South Asian construction workers, and to evaluate its feasibility, acceptability and effectiveness in increasing knowledge of pneumoconiosis, modifying beliefs about pneumoconiosis, and enhancing intention to implement measures for its prevention among the workers. This evaluation was performed using the Reach-Effectiveness-Adoption-Implementation-Maintenance framework. A one-group design was adopted and intervention mapping was used to guide the process of intervention development, while the Health Belief Model guided the development of intervention content. The intervention was delivered at construction sites, ethnic minority associations and South Asian community centres. Data were collected via surveys completed at pre-intervention, post-intervention and 3 months after the intervention. A total of 1002 South Asian construction workers participated in the intervention. The participants reported a moderate-to-large increase in knowledge, perceived susceptibility, perceived severity, perceived benefits, cues to action and self-efficacy (Cohen's d: 0.37-0.89), a small reduction in perceived barriers (Cohen's d = 0.12) and a moderate improvement in attitudes and intention to practice (Cohen's d: 0.45, 0.51) at post-intervention. A follow-up survey of 121 participants found that the implementation of preventive measures appeared to increase. Overall, the findings demonstrate that the implementation of a culturally adapted multimedia educational intervention could be an effective approach to improving knowledge, self-efficacy and intention regarding pneumoconiosis prevention among South Asian construction workers.

Promoting adherence to physical activity among individuals with cardiovascular disease using behavioral counseling: A theory and research-based primer for health care professionals

Physical activity (PA) promotion remains a cornerstone of primary and secondary prevention efforts to reduce morbidity and mortality from cardiovascular disease (CVD). While frontline health care providers (HCPs; e.g., family physicians, cardiologists, registered nurses, nurse practitioners, etc.) are in an optimal position to administer PA-promoting interventions to their patients, many HCPs may feel ill-equipped to address common obstacles to implementing and maintaining complex health behavior change. Behavioral counseling refers to a collection of theory- and empirically-supported strategies and approaches to health behavior promotion that can be learned and applied by HCPs for CVD prevention and treatment. In this selective review, we discuss prominent theories of health behavior change and the empirical intervention literature regarding PA promotion in community and CVD-samples and provide practical recommendations for integrating effective behavioral counseling strategies to clinical practice for frontline HCPs. We argue that behavioral counseling interventions for PA can be effectively executed within the contextual constraints of health settings through subtle shifts in communication strategies and brief counseling approaches. The administration of behavioral counseling for PA by HCPs has enormous potential to reduce CVD incidence and progression at a population level.
