A Culturally Adapted, Telehealth, Community Health Worker Intervention on Blood Pressure Control among South Asian Immigrants with Type II Diabetes: Results from the DREAM Atlanta Intervention.

BACKGROUND: South Asians face a high prevalence of type II diabetes (DMII) and comorbid hypertension (HTN). Community health worker (CHW) interventions have the potential to improve chronic disease outcomes, yet few have been tailored to South Asian populations in the United States. OBJECTIVE: To test the effectiveness of an evidence-based CHW-led and culturally-tailored HTN and DMII management program for South Asian adults with diabetes and comorbid uncontrolled HTN (systolic blood pressure (SBP) > 130 mmHg or diastolic blood pressure (DBP) > 80 mmHg). DESIGN: Randomized-controlled Trial. PARTICIPANTS: South Asian adults with DMII and comorbid HTN. INTERVENTION: The Diabetes Research, Education, and Action for Minorities (DREAM) Atlanta intervention was a CHW telehealth intervention designed to improve blood pressure (BP). The treatment group received five virtual group-based health education sessions, an action plan, and follow-up calls to assess goal setting activities. The control group received only the first session. Main Measures included: feasibility, improvement in BP control, and decreases in SBP, DBP, weight, and hemoglobin A1c (HbA1c). KEY RESULTS: A total of 190 South Asian adults were randomized (97 to the treatment group and 93 to the control group); 94% of treatment group participants completed all 5 telehealth sessions. At endpoint, BP control increased 33.7% (95% CI: 22.5, 44.9, p < 0.001) in the treatment group and 16.5% (95%: 6.2, 26.8, p = 0.003) in the control group; the adjusted intervention effect was 1.8 (95% CI: 1.0, 3.2, p = 0.055). Mean weight decreased by 4.8 pounds (95% CI: -8.2, -1.4, p = 0.006) in the treatment group, and the adjusted intervention effect was -5.2 (95% CI: -9.0, -1.4, p = 0.007. The intervention had an overall retention of 95%. CONCLUSIONS: A culturally-tailored, CHW-led telehealth intervention is feasible and can improve BP control among South Asian Americans with DMII.

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. REGISTRATION: URL: https://www.

Promoting Physical Activity Among Immigrant Asian Americans: Results from Four Community Health Worker Studies.

Racial/ethnic minorities have demonstrated lower rates of physical activity (PA) than non-Hispanic Whites. This study examined outcomes in PA measures after participation in a community health worker (CHW) intervention. We performed a secondary data analysis from four randomized controlled trials utilizing CHWs (n = 842) in New York City (Bangladeshi-diabetes management, Filipino-hypertension management, and Korean and Asian Indian-diabetes prevention). Outcomes included total weekly PA, PA self-efficacy, PA barriers, and PA social interaction. Each measure was examined at baseline and study endpoint. Generalized estimating equation models were fitted to assess the repeated measures over time, while accounting for study group and socio-demographic factors. Moderate PA, recommended PA, and self-efficacy increased significantly among treatment group participants. PA social interaction increased significantly among Filipinos and Asian Indians. In adjusted regression analysis, time x group interaction was significant for all PA outcomes except for PA barriers. Culturally-adapted lifestyle interventions may potentially improve PA-related outcomes in Asian immigrant communities. Trial registration at ClinicalTrials.gov includes: NCT03530579 (RICE Project), NCT02041598 (DREAM Project), and NCT03100812 (AsPIRE).

Evaluation of a Diabetes Prevention Intervention for Korean American immigrants at Risk for Diabetes.

Purpose: Despite the small but growing number of studies documenting the increasing prevalence of diabetes among Korean Americans, no culturally adapted interventions have been developed for Korean Americans at risk for diabetes. We evaluate the efficacy of a culturally tailored lifestyle intervention among Korean American immigrants at risk for diabetes in New York City (NYC). Methods: Korean Americans at risk for diabetes were recruited into a culturally adapted, community health worker (CHW) intervention in NYC. Treatment group participants received 6 group sessions and 10 follow-up phone calls from CHWs over the 6-month period. Control participants received only the first session. Study outcomes included changes in weight, body mass index (BMI), blood pressure, physical activity (PA) and PA behaviors, nutrition behaviors, and diabetes knowledge. Paired t-tests and chi-square tests assessed group differences for each group for each outcome measure. Results: The treatment group reported significant positive changes in recommended weekly PA, PA self-efficacy, PA barriers, nutrition self-efficacy, diabetes knowledge, weight, BMI, and systolic blood pressure compared with control participants. Generalized estimated equations models for repeated measures assessed change across time while adjusting for study arm, time point, and the interaction between study arm and time point. The intervention effect was significant for weekly moderate and vigorous PA, recommended weekly PA, PA self-efficacy, and diabetes knowledge. Conclusions: Results suggest that a culturally adapted lifestyle intervention for Korean American immigrants at risk for diabetes have the potential to improve behaviors associated with cardiovascular disease outcomes and diabetes prevention. Further research among Korean Americans is warranted.

Implementation of a multi-level community-clinical linkage intervention to improve glycemic control among south Asian patients with uncontrolled diabetes: study protocol of the DREAM initiative.

BACKGROUND: A number of studies have identified patient-, provider-, and community-level barriers to effective diabetes management among South Asian Americans, who have a high prevalence of type 2 diabetes. However, no multi-level, integrated community health worker (CHW) models leveraging health information technology (HIT) have been developed to mitigate disease among this population. This paper describes the protocol for a multi-level, community-clinical linkage intervention to improve glycemic control among South Asians with uncontrolled diabetes. METHODS: The study includes three components: 1) building the capacity of primary care practices (PCPs) to utilize electronic health record (EHR) registries to identify patients with uncontrolled diabetes; 2) delivery of a culturally- and linguistically-adapted CHW intervention to improve diabetes self-management; and 3) HIT-enabled linkage to culturally-relevant community resources. The CHW intervention component includes a randomized controlled trial consisting of group education sessions on diabetes management, physical activity, and diet/nutrition. South Asian individuals with type 2 diabetes are recruited from 20 PCPs throughout NYC and randomized at the individual level within each PCP site. A total of 886 individuals will be randomized into treatment or control groups; EHR data collection occurs at screening, 6-, 12-, and 18-month. We hypothesize that individuals receiving the multi-level diabetes management intervention will be 15% more likely than the control group to achieve ≥0.5% point reduction in hemoglobin A1c (HbA1c) at 6-months. Secondary outcomes include change in weight, body mass index, and LDL cholesterol; the increased use of community and social services; and increased health self-efficacy. Additionally, a cost-effectiveness analysis will focus on implementation and healthcare utilization costs to determine the incremental cost per person achieving an HbA1c change of ≥0.5%. DISCUSSION: Final outcomes will provide evidence regarding the effectiveness of a multi-level, integrated EHR-CHW intervention, implemented in small PCP settings to promote diabetes control among an underserved South Asian population. The study leverages multisectoral partnerships, including the local health department, a healthcare payer, and EHR vendors. Study findings will have important implications for the translation of integrated evidence-based strategies to other minority communities and in under-resourced primary care settings. TRIAL REGISTRATION: This study was registered with clinicaltrials.gov: NCT03333044 on November 6, 2017.

A Culturally Adapted Diabetes Prevention Intervention in the New York City Sikh Asian Indian Community Leads to Improvements in Health Behaviors and Outcomes.

INTRODUCTION: Sikh Asian Indians are an underserved, minority group demonstrating high rates of diabetes. Community health workers (CHWs) are effective in addressing health disparities by reaching socially and linguistically isolated populations. There are no culturally-adapted programs for diabetes prevention among Sikh Asian Indians, thus, this study tests the efficacy of a culturally-tailored CHW intervention to improve diabetes prevention-related outcomes among Sikh Asian Indians at-risk for diabetes. METHODS: A quasi-experimental two-arm intervention among Sikh Asian Indian adults at-risk for diabetes and living in New York City (n=160) was conducted in 2013-2014. The treatment group received six monthly CHW group education sessions and ten follow-up phone calls; the control group received the first session. Main outcomes included weight, body mass index (BMI), blood pressure (BP), physical activity (PA), diet, and health self-efficacy. RESULTS: Positive and significant changes in weight, BMI, and diabetes prevention-related indicators were seen among both study groups. However, only treatment group participants showed significant changes over time for weight, BMI, PA self-efficacy, and health-related self-efficacy. Significant between-group differences were seen in adjusted analyses for weight, BMI, systolic BP, total weekly PA, PA self-efficacy, PA social interaction, portion control, barriers to healthy eating, and health self-efficacy. At 6-months, treatment participants were more likely to lose ≥5% and ≥7% of their weight compared to control participants (p=0.071, and p=0.015, respectively). CONCLUSIONS: Findings demonstrate that a culturally-adapted CHW diabetes prevention program in the Sikh community is efficacious, adding to the growing literature on CHWs' capacity to address health inequity among underserved populations.

The DREAM Initiative: study protocol for a randomized controlled trial testing an integrated electronic health record and community health worker intervention to promote weight loss among South Asian patients at risk for diabetes.

BACKGROUND: Electronic health record (EHR)-based interventions that use registries and alerts can improve chronic disease care in primary care settings. Community health worker (CHW) interventions also have been shown to improve chronic disease outcomes, especially in minority communities. Despite their potential, these two approaches have not been tested together, including in small primary care practice (PCP) settings. This paper presents the protocol of Diabetes Research, Education, and Action for Minorities (DREAM) Initiative, a 5-year randomized controlled trial integrating both EHR and CHW approaches into a network of PCPs in New York City (NYC) in order to support weight loss efforts among South Asian patients at risk for diabetes. METHODS/DESIGN: The DREAM Initiative was funded by the National Institute of Diabetes and Digestive and Kidney Diseases (National Institutes of Health). A total of 480 individuals at risk for type 2 diabetes will be enrolled into the intervention group, and an equal number will be included in a matched control group. The EHR intervention components include the provision of technical assistance to participating PCPs regarding prediabetes-related registry reports, alerts, and order sets. The CHW intervention components entail group education sessions on diabetes prevention, including weight loss and nutrition. A mixed-methods approach will be used to evaluate the feasibility, adoption, and impact (≥ 5% weight loss) of the integrated study components. Additionally, a cost effectiveness analysis will be conducted using outcomes, implementation costs, and healthcare claims data to determine the incremental cost per person achieving 5% weight loss. DISCUSSION: This study will be the first to test the efficacy of an integrated EHR-CHW intervention within an underserved, minority population and in a practical setting via a network of small PCPs in NYC. The study's implementation is enhanced through cross-sector partnerships, including the local health department, a healthcare payer, and EHR vendors. Through use of a software platform, the study will also systematically track and monitor CHW referrals to social service organizations. Study findings, including those resulting from cost-effectiveness analyses, will have important implications for translating similar strategies to other minority communities in sustainable ways. TRIAL REGISTRATION: This study protocol has been approved and is made available on ClinicalTrials.gov by NCT03188094 as of 15 June 2017.

A Faith-Based Intervention to Reduce Blood Pressure in Underserved Metropolitan New York Immigrant Communities.

Minority populations, including Asian Americans, face disparities in hypertension compared with non-Hispanic whites. This underscores the need for culturally adapted programs in settings that reach Asian American communities, such as faith-based organizations. We worked collaboratively with community partners to culturally adapt and implement an evidence-based community blood pressure monitoring program for Asian Americans (Asian Indians, Koreans, Filipinos, and Bangladeshis) in metropolitan New York during 2015 and 2016. The program included regularly scheduled volunteer-led screening and counseling events with congregants at faith-based organizations. Among participants with complete 6-month data (n = 348), health-related self-efficacy significantly improved after 6 months, and systolic and diastolic blood pressure was significantly reduced in some subgroups; reductions were highest in participants who self-reported a previous diagnosis of hypertension. Among Asian Americans, faith-based programs may be a replicable, low-cost, sustainable way to increase health-related self-efficacy and decrease blood pressure, specifically among individuals with self-reported hypertension.

Clinical Characteristics and Lifestyle Behaviors in a Population-Based Sample of Chinese and South Asian Immigrants With Hypertension.

BACKGROUND: Asian Americans are the fastest growing racial/ethnic group in the United States. Chinese Americans and their counterparts in Chinese countries have been shown to have an elevated risk of stroke compared to non-Hispanic Whites, while South Asian Americans and their counterparts in South Asian countries have an elevated risk of heart disease. Exactly how cardiovascular disease morbidity varies by Asian subgroup, however, is not well understood. The purpose of this analysis was to identify differences in clinical presentation and lifestyle behaviors between Chinese and South Asian American immigrants vs. non-Hispanic Whites in a representative sample of adults with self-report of physician-diagnosed hypertension. METHODS: Data on adults with self-reported hypertension were obtained from the New York City Community Health Survey 2009-2013 (Chinese: n = 555; South Asian: n = 144; non-Hispanic White: n = 5,987). RESULTS: Compared to non-Hispanic Whites with hypertension, foreign-born Chinese adults with hypertension were of a much lower socioeconomic profile and less likely to have private health insurance, and foreign-born Chinese and South Asian adults with hypertension had lower body mass index (BMI) values (25.3, 26.0 vs. 28.7kg/m(2); P < 0.001). South Asians were younger than non-Hispanic Whites (mean age: 49.5 vs. 62.1 years; P < 0.001) and had poorer diet quality. BMI and diet quality results persisted in multivariable regression models. CONCLUSIONS: Findings from this study highlight important clinical distinctions in hypertensive Chinese and South Asian immigrant communities with respect to age and body size. Whether targeted and culturally appropriate approaches would reduce cardiovascular disease-related mortality in these groups needs further study.

Correlates of Physical Activity Among Middle-Aged and Older Korean Americans at Risk for Diabetes.

PURPOSE: To explore correlates of meeting recommended physical activity (PA) goals among middle-aged and older Korean Americans at risk for diabetes mellitus (DM). DESIGN AND METHODS: PA patterns and their correlates were assessed among 292 middle-aged and older Korean Americans at risk for DM living in New York City using cross-sectional design of baseline information from a diabetes prevention intervention. PA was assessed by self-report of moderate and vigorous activity, results were stratified by age group (45-64 and 65-75 years), and bivariate analyses compared individuals performing less than sufficient PA and individuals performing sufficient PA. Logistic regression was used to calculate adjusted odds ratios predicting sufficient PA. FINDINGS: After adjusting for sex, age group, years lived in the United States, marital status, health insurance, and body mass index (BMI), sufficient PA was associated with male sex, older age, lower BMI, eating vegetables daily, and many PA-specific questions (lack of barriers, confidence, and engagement). When stratified by age group, male sex and eating vegetables daily was no longer significant among Koreans 65 to 75 years of age, and BMI was not significant for either age group. CONCLUSIONS: PA interventions targeting this population may be beneficial and should consider the roles of sex, age, physical and social environment, motivation, and self-efficacy. CLINICAL RELEVANCE: Clinical providers should understand the unique motivations for PA among Korean Americans and recognize the importance of culturally driven strategies to enable lifestyle changes and support successful aging for diverse populations.

Characteristics of Asian American, Native Hawaiian, and Pacific Islander community health worker programs: a systematic review.

Community health workers (CHWs) are frontline health workers who often serve socially and linguistically isolated populations, including Asian American, Native Hawaiian, and Pacific Islander (AA and NHPI) communities in the United States (U.S.) and U.S. territories. We conducted a systematic review of the peer-reviewed literature to assess the characteristics of CHW programs for AA and NHPI communities in the U.S. and U.S. territories, generating a total of 75 articles. Articles were coded using eight domains: ethnic group, health topic, geographic location, funding mechanism, type of analysis reported, prevention/management focus, CHW role, and CHW title. Articles describing results of an intervention or program evaluation, or cost-effectiveness analysis were further coded with seven domains: study design, intervention recruitment and delivery site, mode of intervention delivery, outcomes assessed, key findings, and positive impact. Results revealed gaps in the current literature and point towards recommendations for future CHW research, program, and policy efforts.

Diabetes prevention in the New York City Sikh Asian Indian community: a pilot study.

India has one of the highest burdens of diabetes worldwide, and rates of diabetes are also high among Asian Indian immigrants that have migrated into the United States (U.S.). Sikhs represent a significant portion of Asian Indians in the U.S. Diabetes prevention programs have shown the benefits of using lifestyle intervention to reduce diabetes risk, yet there have been no culturally-tailored programs for diabetes prevention in the Sikh community. Using a quasi-experimental two-arm design, 126 Sikh Asian Indians living in New York City were enrolled in a six-workshop intervention led by community health workers. A total of 108 participants completed baseline and 6-month follow-up surveys between March 2012 and October 2013. Main outcome measures included clinical variables (weight, body mass index (BMI), waist circumference, blood pressure, glucose, and cholesterol) and health behaviors (changes in physical activity, food behaviors, and diabetes knowledge). Changes were significant for the treatment group in weight, BMI, waist circumference, blood pressure, glucose, physical activity, food behaviors, and diabetes knowledge, and between group differences were significant for glucose, diabetes knowledge, portion control, and physical activity social interaction. Retention rates were high. Findings demonstrate that a diabetes prevention program in the Sikh community is acceptable, feasible, and efficacious.

A randomized-controlled, pilot intervention on diabetes prevention and healthy lifestyles in the New York City Korean community.

Asian Americans experience diabetes at a higher rate than non-Hispanic whites. Diabetes prevention programs using lifestyle interventions have been shown to produce beneficial results, yet there have been no culturally-tailored programs for diabetes prevention in the Korean community. We explore the impact and feasibility of a pilot Community Health Worker (CHW) intervention to improve health behaviors and promote diabetes prevention among Korean Americans using a randomized controlled trial. Between 2011 and 2012, a total of 48 Korean Americans at risk for diabetes living in New York City (NYC) participated in the intervention. Participants were allocated to treatment or control groups. A community-based participatory research approach guided development of the intervention, which consisted of 6 workshops held by CHWs on diabetes prevention, nutrition, physical activity, diabetes complications, stress and family support, and access to health care. Changes over 6 months were examined for clinical measurements (weight, BMI, waist circumference, blood pressure, glucose, and cholesterol); health behaviors (physical activity, nutrition, food behaviors, diabetes knowledge, self-efficacy, and mental health); and health access (insurance and self-reported health). In this small pilot study, changes were seen in weight, waist circumference, diastolic blood pressure, physical activity nutrition, diabetes knowledge, and mental health. Qualitative findings provide additional contextual information that inform ways in which CHWs may influence health outcomes. These findings demonstrate that a diabetes prevention program can be successful among a Korean American population in NYC, and important insight is provided for ways that programs can be tailored to meet the needs of vulnerable populations.
