The National Cambodian American Town Hall Meeting: a community dialogue on "eat, walk, sleep" for health

Secondary analysis of a randomized trial testing community health educator interventions for diabetes prevention among refugees with depression: effects on nutrition, physical activity and sleep

BACKGROUND

Refugees have high levels of psychological distress that hamper lifestyle change efforts. We previously reported that community health educator (CHE) diabetes prevention interventions decreased HbA1c and depressive symptoms among Cambodian-American refugees with depression; this paper reports health behavior outcomes of those interventions.

METHODS

Participants were aged 35-75, Khmer speaking, at risk for diabetes, and met study criteria for likely depression by either a) antidepressant medication and/or b) prolonged elevated depressive symptoms. Participants were randomized to one of three CHE interventions: 1) lifestyle intervention called Eat, Walk, Sleep (EWS), 2) EWS plus medication therapy management with a pharmacist/CHE team (EWS + MTM), or, 3) social services (SS; control). Physical activity and sleep were measured with 7 days of actigraphy. Nutrition was measured as carbohydrates as reported in a culturally tailored food frequency questionnaire. Assessments were at baseline, end point (12 months), and follow-up (15 months).

RESULTS

The n = 188 participants were 78% female, average age of 55 years, half had a household income < $20,000, and modal education was 7.0 years. Individuals in the two treatment groups that received the EWS intervention significantly increased their brown rice consumption (p < .001, Cohen's d = 0.76) and their moderate-to-vigorous activity (p = .039, d = 0.32). No intervention changed sleep duration, timing, efficiency or wake after sleep onset. Across groups, individuals who increased brown rice consumption, increased vigorous activity and decreased total sleep time variability showed decreased HbA1c, with small effect sizes.

CONCLUSIONS

CHEs may improve nutrition and physical activity in refugees with depression but more intensive interventions may be required to impact sleep. Improvements in all three behaviors appear to be associated with HbA1c lowering TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT02502929.

Community-based diabetes prevention randomized controlled trial in refugees with depression: effects on metabolic outcomes and depression

Depression and antidepressant medications increase risk for type 2 diabetes. Cambodian-Americans have exceedingly high rates of both depression and diabetes. This paper reports outcomes of a diabetes prevention trial for Cambodian-Americans with depression. Primary outcomes were HbA1c, insulin resistance and depressive symptoms. Participants were aged 35-75, Khmer speaking, at risk for diabetes, and met study criteria for likely depression by either (a) antidepressant medication and/or (b) prolonged elevated depressive symptoms. Participants were randomized to one of three community health worker (CHW) interventions: (1) lifestyle intervention called Eat, Walk, Sleep (EWS), (2) EWS plus medication therapy management sessions with a pharmacist/CHW team to resolve drug therapy problems (EWS + MTM), or, (3) social services (SS; control). Assessments were at baseline, post-treatment (12 months), and follow-up (15 months). The n = 188 participants were 78% female, average age of 55 years, half had a household income < $20,000, and modal educational attainment was 7.0 years. Compared to the other arms, EWS + MTM showed a significant decrease in HbA1c and a trend for reduced inflammation and stress hormones. Depressive symptoms improved for EWS and EWS + MTM relative to SS. There was no change in insulin resistance. Cardiometabolic and mental health can be improved in tandem among immigrant and refugee groups.

Self-reported outcomes of a randomized trial comparing three community health worker interventions for diabetes prevention among Cambodian Americans with depression

OBJECTIVE

Cambodian Americans have complex, interrelated and persistent medical and mental health problems stemming from genocide and the social determinants of health. We examined changes in multiple domains of self-reported health outcomes from a diabetes prevention trial.

METHODS

Cambodian Americans with depression and high risk for diabetes (n = 188) were randomized to one of three community health worker interventions: lifestyle vs lifestyle plus medication therapy management vs social services. Assessments were at baseline, 12- and 15-months.

RESULTS

The typical participant was 55 years old, female, earned below $20,000 annually, and had 7 years of education. About one-third were taking antidepressant medication and over half had elevated depressive symptoms. Relative to social services, lifestyle and lifestyle plus medication therapy management were both similarly effective at increasing diabetes knowledge, nutrition habits, sleep quality and decreasing pain; 2) lifestyle alone was superior to social services for self-reported health; and, 3) all three groups showed improved anxiety and insomnia. There were no effects on physical activity or physical functioning.

CONCLUSION

Community health worker interventions have multiple benefits beyond delaying diabetes.

PRACTICE IMPLICATIONS

Health promotion programs that are designed and delivered appropriately can impact even hard to reach and hard to treat groups.

Pharmacists and community health workers improve medication-related process outcomes among Cambodian Americans with depression and risk for diabetes

BACKGROUND

Cambodian Americans have high rates of cardiometabolic and psychiatric disorders and disadvantaged social determinants of health (SDOH). These factors can make it challenging to resolve drug therapy problems (DTPs) and improve medication-related outcomes. This manuscript reports planned analyses from a randomized controlled trial in which participants were randomized to one of 3 treatment arms: (1) community health worker (CHW)-delivered lifestyle intervention called Eat, Walk, sleep (EWS), (2) EWS plus pharmacist/CHW-delivered medication therapy management (EWS + MTM), or (3) social services (SS: control).

OBJECTIVES

We compared the 3 arms on changes in self-reported medication adherence, barriers, and beliefs. Within the EWS + MTM arm only, we assessed the impact of EWS + MTM on DTP resolution and examined predictors of DTP resolution.

METHODS

Cambodian Americans at the age of 35-75 years at high risk of developing diabetes and meeting the criteria for likely depression (N = 188) were randomized (EWS, n = 67; EWS + MTM, n = 63; SS, n = 50; control). For all participants, self-reported surveys were collected at baseline, 12 months, and 15 months. DTPs were assessed on the same schedule but only for participants in the EWS + MTM.

RESULTS

All 3 groups reported a significant decrease in barriers to taking medications. Compared with the other arms, the EWS + MTM arm reported a decrease in forgetting to take medications at 15 months. In the EWS + MTM arm, mean DTPs per patient was 6.57 and 84% of DTPs were resolved. SDOH predictors of DTP resolution included years of education (odds ratio [OR] 0.94, P = 0.016), ability to write English (OR 0.73, P = 0.015), difficulty communicating with provider (OR 1.39, P < 0.001), private insurance (OR 1.99, P = 0.030), disability (OR 0.51, P = 0.008), and years living under Pol Pot (OR 0.66, P = 0.045). Medication barriers at baseline predicted DTP resolution (OR 0.79, P = 0.019) such that each additional barrier was associated with a 21% reduction (1-0.79) in the odds of having a resolution.

CONCLUSION

CHWs can reduce medications barriers and help pharmacists reduce DTPs in disadvantaged populations.

A randomized trial to decrease risk for diabetes among Cambodian Americans with depression: Intervention development, baseline characteristics and process outcomes

Background:

Depression and antidepressant medications are associated with increased risk for type 2 diabetes. It is not known if diabetes can be prevented in the setting of depression. Cambodian Americans have high rates of both depression and diabetes. This paper reports intervention development, experimental design, baseline characteristics, and process outcomes of diabetes prevention interventions for Cambodian Americans with depression, “Diabetes Risk Reduction through Eat, Walk, Sleep and Medication Therapy Management” (DREAM).

Methods:

Participants were aged 35–75, Khmer speaking, at high risk for developing diabetes, and met criteria for likely depression by either a) antidepressant medication and/or b) elevated depressive symptoms at two time-points during a study eligibility period. Treatment arms were: 1) community health educator (CHE) delivered lifestyle intervention called Eat, Walk, Sleep (EWS), 2) EWS plus pharmacist/CHE-delivered medication therapy management (EWS + MTM), and, 3) social services (SS; control).

Results:

188 participants were randomized. Treatment fidelity was high (98% checklist adherence) and on a scale from 0 to 3, participants reported high EWS treatment satisfaction (M = 2.9, SD = 0.2), group cohesion (M = 2.9, SD = 0.3), and therapeutic alliance to CHEs (M = 2.9, SD = 0.2) and to pharmacists (2.9, SD = 0.3). Attendance was challenging but highly successful; in EWS, 99% attended ≥ one session and 86% completed ≥ 24 sessions, M = 27.3 (SD = 3.7) sessions. Of those randomized to EWS + MTM, 98% attended at least one MTM session and 77%) completed ≥ 4 sessions. Retention was high, 95% at 12-month and 96% at 15-month assessments.

Conclusions:

The interventions were successfully implemented. Lessons learned and suggestions for future trials are offered.

Remote Peer Learning Between US and Cambodian Lay Health Workers to Improve Outcomes for Cambodians with Type 2 Diabetes: a Pilot Study

BACKGROUND

This paper reports a single-group, pre-post pilot of a peer-learning intervention between community health workers (CHWs) in the USA and Village Health Support Guides (Guides) in Cambodia to improve outcomes for Cambodians with type 2 diabetes (T2D).

METHOD

Two US-based CHWs were trained in a culturally derived cardiometabolic education curriculum called Eat, Walk, Sleep (EWS) and they were also trained in principles of peer learning. They in turn trained five Cambodia-based Guides remotely through videoconference with a phablet in EWS. Finally, Cambodia-based Guides met with 58 patients with diabetes, face-to-face in their villages, monthly for 6 months to deliver EWS. US-based CHWs and Cambodia-based Guides responded to surveys at baseline and post-treatment. Patients responded to surveys and provided blood pressure and blood samples at baseline and post-treatment.

RESULTS

For US-based CHWs, scores on all surveys of diabetes knowledge, self-evaluation, job satisfaction, and information technology improved, though no statistical tests were run due to sample size. For Cambodia-based Guides, all scores on these same measures improved except for job satisfaction. For patients, n = 60 consented, 2 withdrew, and 7 were lost to follow-up leaving n = 51 for analysis. In paired t tests, patients showed significantly decreased A1c, decreased systolic and diastolic blood pressures, improved attitudes toward medicines, and a trend for switching from all-white to part-brown rice. No changes were detected in self-reported physical activity, medication adherence, sleep quality, or frequency or amount of rice consumed.

CONCLUSION

If proven effective in a controlled trial, cross-country peer learning could eventually help other diaspora communities.

A Health Profile and Overview of Healthcare Experiences of Cambodian American Refugees and Immigrants Residing in Southern California

Asian Americans are understudied in health research and often aggregated into one homogenous group, thereby disguising disparities across subgroups. Cambodian Americans, one of the largest refugee communities in the United States, may be at high risk for adverse health outcomes. This study compares the health status and healthcare experiences of Cambodian American refugees and immigrants. Data were collected via questionnaires and medical records from two community clinics in Southern California (n = 308). Chi square and t-tests examined the socio-demographic differences between immigrants and refugees, and ANCOVA models compared the mean differences in responses for each outcome, adjusting for age at immigration, education level, and clinic site. Cambodian American refugees reported overall lower levels of health-related quality of life (all p's < 0.05 in unadjusted models) and self-rated health [unadjusted means (SD) = 18.2 (16.8) vs. 21.7 (13.7), p < 0.05], but either similar or more positive healthcare experiences than Cambodian American immigrants. In adjusted analyses, refugees had higher rates of diabetes and cardiovascular disease risk (e.g. heart condition and hypertension; p's < 0.05) compared to Cambodian American immigrants. There were minimal differences in self-reported health behaviors between the two groups. There is a need for more health promotion efforts among Cambodian American refugees and immigrants to improve their health outcomes and perceived wellbeing.

Training Cambodian Village Health Support Guides in Diabetes Prevention: Effects on Guides' Knowledge and Teaching Activities Over 6 Months

BACKGROUND

Type 2 diabetes is a pressing public health concern in Cambodia, a country with limited human resource capacity due to genocide. Cambodian village health support guides (Guides) promote health at the local level.

PURPOSE

This paper reports preliminary results of training Guides in diabetes prevention.

METHOD

The curriculum, called Eat, Walk, Sleep was delivered to Guides in Siem Reap province once over 3 h. Participants completed a pretest and posttest on diabetes knowledge. Guides were offered continuing education through Eat, Walk, Sleep resources and were encouraged to teach Eat, Walk, Sleep in their villages. For each of 6 months following their training, Guides completed a checklist regarding their activities.

RESULTS

One hundred eighty-five Guides attended one of ten trainings. Knowledge scores increased significantly from pretest to posttest. During 6 months of follow-up, n = 159 Guides (85 %) completed at least one monthly checklist. Guides reported high rates of uptake and delivery of the Eat, Walk, Sleep curriculum and moderate rates of continuing education about diabetes.

CONCLUSION

Diabetes prevention in Cambodia is nascent. Guides show excellent uptake and dissemination of the curriculum. Future research should examine effect of support for Guide activities and the effect of the curriculum on villager health behaviors, and ultimately, on rates of type 2 diabetes.

Diabetes among refugee populations: what newly arriving refugees can learn from resettled Cambodians

A growing body of literature suggests that cardiometabolic disease generally and type 2 diabetes specifically are problems among refugee groups. This paper reviews rates of cardiometabolic disease and type 2 diabetes among refugees and highlights their unique risk factors including history of malnutrition, psychiatric disorders, psychiatric medications, lifestyle changes toward urbanization and industrialization, social isolation, and a poor profile on the social determinants of health. Promising interventions are presented for preventing and treating diabetes in these groups. Such interventions emphasize well-coordinated medical and mental health care delivered by cross-cultural and multidisciplinary teams including community health workers that are well integrated into the community. Finally, recommendations for service, policy, and research are made. The authors draw on local data and clinical experience of our collective work with Cambodian American refugees whose 30-year trajectory illustrates the consequences of ignoring diabetes and its risk factors in more recent, and soon to be arriving, refugee cohorts.
