ABSTRACT

BACKGROUND: Healthcare workers (HCWs) including community health extension workers (CHEWs) in the Federal Capital Territory, Nigeria participated in a hypertension training series following the Extension for Community Healthcare Outcomes (ECHO) model which leverages technology and a practical peer-to-peer learning framework to virtually train healthcare practitioners. We sought to evaluate the patient-level effects of the hypertension ECHO series. METHODS: HCWs from 12 of 33 eligible primary healthcare centers (PHCs) in the Hypertension Treatment in Nigeria Program (NCT04158154) were selected to participate in a seven-part hypertension ECHO series from August 2022 to April 2023. Concurrent Hypertension Treatment in Nigeria Program patient data were used to evaluate changes in hypertension treatment and control rates, and adherence to Nigeria's hypertension treatment protocol. Outcomes were compared between the 12 PHCs in the ECHO program and the 21 which were not. RESULTS: Between July 2022 and June 2023, 16,691 PHC visits were documented among 4340 individuals (ECHO: n = 1428 [33%], non-ECHO: n = 2912 [67%]). Patients were on average (SD) 51.5 (12.0) years old, and one-third were male (n = 1372, 32%) with no differences between cohorts in either characteristic (p ≥ 0.05 for both). Blood pressures at enrollment were higher in the ECHO cohort compared to the non-ECHO cohort (systolic p < 0.0001 and diastolic p = 0.0001), and patients were less likely to be treated with multiple medications (p < 0.0001). Treatment rates were similar at baseline (ECHO: 94.0% and Non-ECHO: 94.7%) and increased at a higher rate (interaction p = 0.045) in the ECHO cohort over time. After adjustment for baseline and within site variation, the difference was attenuated (interaction p = 0.37). Over time, control rates increased and medication protocol adherence decreased, with no differences between cohorts. Staffing levels, adult patient visits, and rates of hypertension screening and empanelment were similar between ECHO and non-ECHO cohorts (p ≥ 0.05 for all). CONCLUSIONS: The ECHO series was associated with moderately increased hypertension treatment rates and did not adversely affect staffing or clinical capacity among PHCs in the Federal Capital Territory, Nigeria. These results may be used to inform strategies to support scaling hypertension education among frontline HCWs throughout Nigeria, and use of the ECHO model for CHEWs. TRIAL REGISTRATION: The Hypertension Treatment in Nigeria Program was prospectively registered on November 8, 2019 at www. CLINICALTRIALS: gov (NCT04158154; https://clinicaltrials.gov/ct2/show/NCT04158154 ).

ABSTRACT

Importance: South Asian adults in the US experience excess cardiovascular disease (CVD) compared with other racial and ethnic groups. The effectiveness and reach of guideline-recommended lifestyle interventions have not been evaluated in this population. Objective: To evaluate whether a culturally adapted, group lifestyle intervention will improve CVD risk factors more effectively than written health education materials among US South Asian adults. Design, Setting, and Participants: This single-blind randomized clinical trial was conducted from March 6, 2018, to February 11, 2023 at community sites in the Chicago, Illinois, metropolitan area. South Asian adults aged 18 to 65 years who were overweight or obese, had no history of CVD events, and had at least 1 additional CVD risk factor (hypertension, dyslipidemia, prediabetes, or diabetes) were eligible for inclusion. Intervention: A 16-week, culturally adapted, group-based lifestyle intervention led by community health coaches. Lifestyle modification counseling was delivered in English, Gujarati, Hindi, and Urdu. Participants tracked their diet and physical activity (PA) and received 4 optional group maintenance sessions between months 5 and 11 of follow-up. The intervention was delivered in person prior to the onset of the COVID-19 pandemic and via videoconference starting in March 2020. The control group received written health education materials, delivered monthly. Main Outcomes and Measures: Primary outcomes were the between-group differences in CVD risk factor changes from baseline to 12 months, including weight, systolic blood pressure (SBP), diastolic blood pressure (DBP), glycated hemoglobin (HbA1c), and total cholesterol, estimated using multivariate mixed-effects regression models. Secondary outcomes were self-reported diet quality, PA, and self-efficacy, estimated using univariate mixed-effects regression models. Results: Among 549 randomized participants, 318 (57.9%) were women, and mean (SD) participant age was 49.2 (9.5) years. Mean differences in CVD risk factor changes from baseline to 12 months in the intervention vs control group were calculated for weight (mean difference, -0.07 kg; 95% CI, -0.55 to 0.42), SBP (mean difference, 0.47 mm Hg; 95% CI, -1.85 to 2.79), DBP (mean difference, 0.44 mm Hg; 95% CI, -1.06 to 1.95), cholesterol (mean difference, -2.47 mg/dL; 95% CI, -8.51 to 3.57), and HbA1c (mean difference, -0.07%; 95% CI -0.20% to 0.07%). Intervention participation was associated with greater improvements in dietary quality, PA, and self-efficacy than control. Conclusions and Relevance: In the SAHELI randomized clinical trial, a culturally adapted, group lifestyle intervention was not more effective than written health education materials for CVD risk factor reduction among US South Asian adults, but the intervention was associated with small improvements in self-reported health behaviors. Effective CVD prevention interventions for this elevated-risk population require further investigation. Trial Registration: ClinicalTrials.gov Identifier: NCT03336255.

ABSTRACT

BACKGROUND: National-level differences in myocardial infarction (MI) quality of care among Asian patients in the United States are unclear. We assessed the quality of MI care in the 6 largest US Asian ethnic groups. METHODS: Patients aged ≥18 years with ST-segment-elevation MI or non-ST-segment-elevation MI in the Get With The Guidelines-Coronary Artery Disease registry (711 US hospitals, 2015-2021) were assessed. The odds of MI-related quality of care and process outcomes were evaluated in Asian Indian, Chinese, Filipino, Japanese, Korean, Vietnamese, and other Asian adults compared with non-Hispanic White adults. Sex-stratified logistic regression models were adjusted for age and clinical characteristics. RESULTS: There were 5691 Asian patients (1520 Asian Indian, 422 Chinese, 430 Filipino, 114 Japanese, 283 Korean, 553 Vietnamese, and 2369 other Asian) and 141 271 non-Hispanic White patients, overall 30% female, and mean age of 66.5 years. Relative to non-Hispanic White adults, among patients with ST-segment-elevation MI, door-to-ECG time ≤10 minutes was less likely in Asian Indian (adjusted odds ratio [aOR], 0.64 [95% CI, 0.50-0.82]), Chinese (aOR, 0.65 [95% CI, 0.46-0.93]), and Korean (aOR, 0.57 [95% CI, 0.33-0.97]) men and in other Asian women (aOR, 0.61 [95% CI, 0.41-0.90]). Door-to-balloon time ≤90 minutes was less likely in Asian Indian men (aOR, 0.71 [95% CI, 0.56-0.90]) and Filipina women (aOR, 0.48 [95% CI, 0.24-0.98]). In patients with ST-segment-elevation MI or non-ST-segment-elevation MI, optimal medical therapy for MI was less likely in Korean men (aOR, 0.65 [95% CI, 0.47-0.90]) and more likely in Asian Indian men (aOR, 1.22 [95% CI, 1.06-1.40]) and women (aOR, 1.32 [95% CI, 1.04-1.67]) and Filipina women (aOR, 1.84 [95% CI, 1.27-2.67]). CONCLUSIONS: MI quality of care varies among US Asian patients with ST-segment-elevation MI and non-ST-segment-elevation MI. Quality improvement programs must identify and address the factors that result in suboptimal MI quality of care among US Asian patients.

ABSTRACT

BACKGROUND: South Asian Americans bear a high burden of atherosclerotic cardiovascular disease (ASCVD), but little is known about the sustainability of evidence-based interventions (EBI) to prevent ASCVD in this population. Using community-based participatory research, we previously developed and implemented the South Asian Healthy Lifestyle Intervention (SAHELI), a culturally-adapted EBI targeting diet, physical activity, and stress management. In this study, we use the Integrated Sustainability Framework to investigate multisectoral partners' perceptions of organizational factors influencing SAHELI sustainability and strategies for ensuring sustainability. METHODS: From 2022 to 2023, we conducted a mixed-methods study (quant- > QUAL) with 17 SAHELI partners in the Chicago area. Partners' settings included: community organization, school district, public health department, and healthcare system. Descriptive statistics summarized quantitative results. Two coders used a hybrid thematic analysis approach to identify qualitative themes. Qualitative and quantitative data were integrated and analyzed using mixed methods. RESULTS: Surveys (score range 1-5: higher scores indicate facilitators; lower scores indicate barriers) indicated SAHELI sustainability facilitators to be its "responsiveness to community values and needs" (mean = 4.9). Barriers were "financial support" (mean = 3.5), "infrastructure/capacity to support sustainment" (mean = 4.2), and "implementation leadership" (mean = 4.3). Qualitative findings confirmed quantitative findings that SAHELI provided culturally-tailored cardiovascular health education responsive to the needs of the South Asian American community, increased attention to health issues, and transformed perceptions of research among community members. Qualitative findings expanded upon quantitative findings, showing that the organizational fit of SAHELI was a facilitator to sustainability while competing priorities were barriers for partners from the public health department and health system. Partners from the public health department and health system discussed challenges in offering culturally-tailored programming exclusively for one targeted population. Sustainability strategies envisioned by partners included: transitioning SAHELI to a program delivered by community members; integrating components of SAHELI into other programs; and expanding SAHELI to other populations. Modifications made to SAHELI (i.e., virtual instead of in-person delivery) had both positive and negative implications for sustainability. DISCUSSION: This study identifies common sustainability barriers and facilitators across different sectors, as well as those specific to certain settings. Aligning health equity interventions with community needs and values, organizational activities, and local context and resources is critical for sustainability. Challenges also arise from balancing the needs of specific populations against providing programming for broader audiences.

ABSTRACT

Few prospective studies examine multilevel resilience resources and psychosocial factors in relation to cardiovascular health and disease. Recent research indicates that resilience resources are associated with a reduction in the incidence of cardiovascular disease-related events, but few studies have examined this relationship across different racial/ethnic populations or in large cohorts. Harmonization may address these limitations because it allows data from several cohorts to be analyzed together, potentially increasing sample size and in turn power overall and in minority populations. This paper describes the process involved in combining three cardiovascular health-focused cohorts: Jackson Heart Study, Multi-Ethnic Study of Atherosclerosis, and Mediators of Atherosclerosis in South Asians Living in America Study. Using a systematic process, we identified appropriate data harmonization techniques to use in harmonizing variables across cohorts. Variables included exposures (e.g., resilience resources), outcomes (e.g., American Heart Association's Life's Simple 7), and covariates (e.g., race and ethnicity). Post harmonization examinations included psychometric analyses of the harmonized variables. A total of 13,284 participants were included in the final harmonized dataset. This project provides opportunities for future research in resilience resources and informs future studies that need to harmonize data. Results based on the harmonized dataset could inform interventions and policies.

ABSTRACT

Importance: The high prevalence of hypertension calls for broad, multisector responses that foster prevention and care services, with the goal of leveraging high-quality treatment as a means of reducing hypertension incidence. Health care system improvements require stakeholder input from across the care continuum to identify gaps and inform interventions that improve hypertension care service, delivery, and retention; system dynamics modeling offers a participatory research approach through which stakeholders learn about system complexity and ways to model sustainable system-level improvements. Objective: To assess the association of simulated interventions with hypertension care retention rates in the Nigerian primary health care system using system dynamics modeling. Design, Setting, and Participants: This decision analytical model used a participatory research approach involving stakeholder workshops conducted in July and October 2022 to gather insights and inform the development of a system dynamics model designed to simulate the association of various interventions with retention in hypertension care. The study focused on the primary health care system in Nigeria, engaging stakeholders from various sectors involved in hypertension care, including patients, community health extension workers, nurses, pharmacists, researchers, administrators, policymakers, and physicians. Exposure: Simulated intervention packages. Main Outcomes and Measures: Retention rate in hypertension care at 12, 24, and 36 months, modeled to estimate the effectiveness of the interventions. Results: A total of 16 stakeholders participated in the workshops (mean [SD] age, 46.5 [8.6] years; 9 [56.3%] male). Training of health care workers was estimated to be the most effective single implementation strategy for improving retention in hypertension care in Nigeria, with estimated retention rates of 29.7% (95% CI, 27.8%-31.2%) at 12 months and 27.1% (95% CI, 26.0%-28.3%) at 24 months. Integrated intervention packages were associated with the greatest improvements in hypertension care retention overall, with modeled retention rates of 72.4% (95% CI, 68.4%-76.4%), 68.1% (95% CI, 64.5%-71.7%), and 67.1% (95% CI, 64.5%-71.1%) at 12, 24, and 36 months, respectively. Conclusions and Relevance: This decision analytical model study showed that community-based participatory research could be used to estimate the potential effectiveness of interventions for improving retention in hypertension care. Integrated intervention packages may be the most promising strategies.

ABSTRACT

BACKGROUND: Healthy plant-based diets have been associated with lower risk of type 2 diabetes (T2D). Metabolomics can be leveraged to identify potential pathways through which diet influences disease risk. OBJECTIVES: This study aimed to identify profiles of serum metabolites reflective of plant-based diets of varying quality and examine associations with cardiometabolic risk and T2D. METHODS: We included data from 687 participants of the Mediators of Atherosclerosis in South Asians Living in America (MASALA) cohort. An overall plant-based diet index (PDI), healthy PDI (hPDI), and unhealthy PDI (uPDI) were estimated from food frequency questionnaires. Serum metabolites were assayed using ultraperformance liquid chromatography mass spectrometry. Elastic net regression was used to identify sets of metabolites predictive of each diet index, and metabolite profile scores were calculated as the weighted sum of the selected metabolites. Cross-sectional associations between metabolite profile scores and cardiometabolic measures and prospective associations with incident T2D were evaluated with multivariable-adjusted linear and logistic regressions. RESULTS: Metabolite profiles for PDI, hPDI, and uPDI consisted of n = 51, 55, and 45 metabolites, respectively. Metabolites strongly positively correlated with diet indices included phosphatidylcholine (16:0/18:3) for PDI, phosphatidylethanolamine (20:1/20:4) and pantothenate for hPDI, and lysophosphatidylglycerol (18:2/0:0), proline, and lauric acid for uPDI. Higher metabolite profile scores for PDI and hPDI were associated with lower glycemia and lipids measures, whereas a higher uPDI metabolite score was associated with higher triglycerides and lower low density lipoprotein cholesterol and high density lipoprotein cholesterol. A higher metabolite score for hPDI was additionally associated with lower adiposity measures, higher liver fat attenuation, higher adiponectin, lower odds of overweight (odds ratio [OR]: 0.64; 95% confidence interval [CI]: 0.51, 0.81) and obesity (OR: 0.59; 95% CI: 0.48, 0.74), and lower odds of incident T2D (OR: 0.66; 95% CI: 0.45, 0.97). CONCLUSIONS: Metabolite profiles of different plant-based diets were identified. Metabolite profiles of overall and healthy plant-based diets were associated with favorable cardiometabolic risk profiles.

ABSTRACT

Importance: Persistent symptoms and disability following SARS-CoV-2 infection, known as post-COVID-19 condition or "long COVID," are frequently reported and pose a substantial personal and societal burden. Objective: To determine time to recovery following SARS-CoV-2 infection and identify factors associated with recovery by 90 days. Design, Setting, and Participants: For this prospective cohort study, standardized ascertainment of SARS-CoV-2 infection was conducted starting in April 1, 2020, across 14 ongoing National Institutes of Health-funded cohorts that have enrolled and followed participants since 1971. This report includes data collected through February 28, 2023, on adults aged 18 years or older with self-reported SARS-CoV-2 infection. Exposure: Preinfection health conditions and lifestyle factors assessed before and during the pandemic via prepandemic examinations and pandemic-era questionnaires. Main Outcomes and Measures: Probability of nonrecovery by 90 days and restricted mean recovery times were estimated using Kaplan-Meier curves, and Cox proportional hazards regression was performed to assess multivariable-adjusted associations with recovery by 90 days. Results: Of 4708 participants with self-reported SARS-CoV-2 infection (mean [SD] age, 61.3 [13.8] years; 2952 women [62.7%]), an estimated 22.5% (95% CI, 21.2%-23.7%) did not recover by 90 days post infection. Median (IQR) time to recovery was 20 (8-75) days. By 90 days post infection, there were significant differences in restricted mean recovery time according to sociodemographic, clinical, and lifestyle characteristics, particularly by acute infection severity (outpatient vs critical hospitalization, 32.9 days [95% CI, 31.9-33.9 days] vs 57.6 days [95% CI, 51.9-63.3 days]; log-rank P < .001). Recovery by 90 days post infection was associated with vaccination prior to infection (hazard ratio [HR], 1.30; 95% CI, 1.11-1.51) and infection during the sixth (Omicron variant) vs first wave (HR, 1.25; 95% CI, 1.06-1.49). These associations were mediated by reduced severity of acute infection (33.4% and 17.6%, respectively). Recovery was unfavorably associated with female sex (HR, 0.85; 95% CI, 0.79-0.92) and prepandemic clinical cardiovascular disease (HR, 0.84; 95% CI, 0.71-0.99). No significant multivariable-adjusted associations were observed for age, educational attainment, smoking history, obesity, diabetes, chronic kidney disease, asthma, chronic obstructive pulmonary disease, or elevated depressive symptoms. Results were similar for reinfections. Conclusions and Relevance: In this cohort study, more than 1 in 5 adults did not recover within 3 months of SARS-CoV-2 infection. Recovery within 3 months was less likely in women and those with preexisting cardiovascular disease and more likely in those with COVID-19 vaccination or infection during the Omicron variant wave.

ABSTRACT

New approaches are needed to lower blood pressure (BP) given persistently low control rates. QUARTET USA sought to evaluate the effect of four-drug, quarter-dose BP lowering combination in patients with hypertension. QUARTET USA was a randomized (1:1), double-blinded trial conducted in federally qualified health centers among adults with hypertension. Participants received either a quadpill of candesartan 2 mg, amlodipine 1.25 mg, indapamide 0.625 mg, and bisoprolol 2.5 mg or candesartan 8 mg for 12 weeks. If BP was >130/>80 mm Hg at 6 weeks in either arm, then participants received open label add-on amlodipine 5 mg. The primary outcome was mean change in systolic blood pressure (SBP) at 12 weeks, controlling for baseline BP. Secondary outcomes included mean change in diastolic blood pressure (DBP), and safety included serious adverse events, relevant adverse drug effects, and electrolyte abnormalities. Among 62 participants randomized between August 2019-May 2022 (n = 32 intervention, n = 30 control), mean (SD) age was 52 (11.5) years, 45% were female, 73% identified as Hispanic, and 18% identified as Black. Baseline mean (SD) SBP was 138.1 (11.2) mmHg, and baseline mean (SD) DBP was 84.3 (10.5) mmHg. In a modified intention-to-treat analysis, there was no significant difference in SBP (-4.8 mm Hg [95% CI: -10.8, 1.3, p = 0.123] and a -4.9 mmHg (95% CI: -8.6, -1.3, p = 0.009) greater mean DBP change in the intervention arm compared with the control arm at 12 weeks. Adverse events did not differ significantly between arms. The quadpill had a similar SBP and greater DBP lowering effect compared with candesartan 8 mg. Trial registration number: NCT03640312.

ABSTRACT

Background: Social and psychosocial determinants are associated with cardiovascular health (CVH). Objectives: To quantify the contributions of social and psychosocial factors to racial/ethnic differences in CVH. Methods: In the Multi-Ethnic Study of Atherosclerosis and Mediators of Atherosclerosis in South Asians Living in America cohorts, Kitagawa-Blinder-Oaxaca decomposition quantified the contributions of social and psychosocial factors to differences in mean CVH score (range 0-14) in Black, Chinese, Hispanic, or South Asian compared with White participants. Results: Among 7,978 adults (mean age 61 [SD 10] years, 52 % female), there were 1,892 Black (mean CVH score for decomposition analysis 7.96 [SD 2.1]), 804 Chinese (CVH 9.69 [1.8]), 1,496 Hispanic (CVH 8.00 [2.1]), 1,164 South Asian (CVH 9.16 [2.0]), and 2,622 White (CVH 8.91 [2.1]) participants. The factors that were associated with the largest magnitude of explained differences in mean CVH score were income for Black participants (if mean income in Black participants were equal to White participants, Black participants' mean CVH score would be 0.14 [SE 0.05] points higher); place of birth for Chinese participants (if proportion of US-born and foreign-born individuals among Chinese adults were equivalent to White participants, Chinese participants' mean CVH score would be 0.22 [0.10] points lower); and education for Hispanic and South Asian participants (if educational attainment were equivalent to White participants, Hispanic and South Asian participants' mean CVH score would be 0.55 [0.11] points higher and 0.37 [0.11] points lower, respectively). Conclusions: In these multiethnic US cohorts, social and psychosocial factors were associated with racial/ethnic differences in CVH.

ABSTRACT

BACKGROUND: South Asians are at higher risk for type 2 diabetes (T2D) than many other race/ethnic groups. Ectopic adiposity, specifically hepatic steatosis and visceral fat may partially explain this. Our objective was to derive metabolite risk scores for ectopic adiposity and assess associations with incident T2D in South Asians. METHODS: We examined 550 participants in the Mediators of Atherosclerosis in South Asians Living in America (MASALA) cohort study aged 40-84 years without known cardiovascular disease or T2D and with metabolomic data. Computed tomography scans at baseline assessed hepatic attenuation and visceral fat area, and fasting serum specimens at baseline and after 5 years assessed T2D. LC-MS-based untargeted metabolomic analysis was performed followed by targeted integration and reporting of known signals. Elastic net regularized linear regression analyses was used to derive risk scores for hepatic steatosis and visceral fat using weighted coefficients. Logistic regression models associated metabolite risk score and incident T2D, adjusting for age, gender, study site, BMI, physical activity, diet quality, energy intake and use of cholesterol-lowering medication. RESULTS: Average age of participants was 55 years, 36% women with an average body mass index (BMI) of 25 kg/m2 and 6% prevalence of hepatic steatosis, with 47 cases of incident T2D at 5 years. There were 445 metabolites of known identity. Of these, 313 metabolites were included in the MET-Visc score and 267 in the MET-Liver score. In most fully adjusted models, MET-Liver (OR 2.04 [95% CI 1.38, 3.03]) and MET-Visc (OR 2.80 [1.75, 4.46]) were associated with higher odds of T2D. These associations remained significant after adjustment for measured adiposity. CONCLUSIONS: Metabolite risk scores for intrahepatic fat and visceral fat were strongly related to incident T2D independent of measured adiposity. Use of these biomarkers to target risk stratification may help capture pre-clinical metabolic abnormalities.

ABSTRACT

BACKGROUND: This convergent parallel-design mixed-methods process evaluation of the QUARTET USA (Quadruple Ultra-Low-Dose Treatment for Hypertension USA) clinical trial (NCT03640312) explores patient and health care professional perceptions about the use of low-dose quadruple therapy (LDQT) as a novel strategy for hypertension management. METHODS AND RESULTS: A survey of all 62 patients enrolled in the QUARTET USA trial was conducted. A subsample of 13 patients and 11 health care professionals, recruited via purposive sampling, took part in semistructured interviews. At enrollment, 68% of participants (mean [SD] age, 51.7 [11.5] years; 56% self-identified as Hispanic: Mexican ethnicity, 16% as Hispanic: other ethnicity, 16% as Black race, 8% as White race, and 1.6% as South Asian race) reported that their current health depended on blood pressure medications, and 48% were concerned about blood pressure medications. At trial completion, 80% were satisfied with LDQT, 96% were certain the benefits of taking LDQT outweighed the disadvantages, and 96% reported that LDQT was convenient to take. Both patients and health care professionals found LDQT acceptable because it reduced patients' perceived pill burden and facilitated medication adherence. Health care professionals stated that a perceived limitation of LDQT was the inability to titrate doses. Steps to facilitate LDQT implementation include introducing stepped-care combinations and treatment protocols, inclusion in clinical practice guidelines, and eliminating patient cost barriers. CONCLUSIONS: LDQT was an acceptable strategy for hypertension treatment among patients and health care professionals involved in the QUARTET USA clinical trial. Although LDQT was generally perceived as beneficial for maintaining patients' blood pressure control and facilitating adherence, some clinicians perceived limitations in titration inflexibility, adverse effects, and costs.

ABSTRACT

Background: The Extension for Community Health Outcomes (ECHO) model has been used extensively to link care providers in rural communities with experts with the aim of improving local patient care. Objective: The aim of this qualitative research study was to assess the feasibility, acceptability, perceived needs, and contextual factors to guide implementation of a hypertension focused ECHO program for Community Health Extension Workers (CHEWs) in the Federal Capital Territory, Nigeria. Methods: From September 2020 to December 2020, key informant interviews were performed with seven global organizations (hubs) providing ECHO training focused on cardiovascular disease or nephrology to identify contextual factors and implementation strategies used by each hub. In February 2022, seven focus group discussions were performed with 42 frontline healthcare workers in the Federal Capital Territory to inform local adaptation of a hypertension ECHO program. Directed content analysis identified major themes which were mapped to the Consolidated Framework for Implementation Research. Qualitative analyses were performed using Dedoose, and results were synthesized using the Implementation Research Logic Model. Results: We found both barriers and facilitators across the Consolidated Framework for Implementation Research domains that mapped to a number of constructs in each one. The results of these analyses confirmed that the core components of the ECHO model are a feasible and appropriate intervention for hypertension education of healthcare workers. However, implementing the ECHO program within the Federal Capital Territory may require strategies such as utilizing communications resources effectively, developing incentives to motivate initial participation, and providing rewards or recognition for ongoing engagement. Conclusions: These results provide valuable formative insights to guide implementation of our proposed hypertension ECHO program for CHEWs in the Federal Capital Territory, Nigeria. This information was used for key decisions around: 1) scope and content of training, 2) format and frequency, 3) selection of implementation strategies, and 4) building a community of practice.

ABSTRACT

PURPOSE: South Asian (SA) persons have increased risks for diabetes mellitus (DM) and atherosclerotic cardiovascular disease (ASCVD). We examined whether the association of DM with subclinical atherosclerosis assessed by coronary artery calcium (CAC) differs in SA versus other ethnic groups. METHODS: We studied adults from the Multi-Ethnic Study of Atherosclerosis and the Mediators of Atherosclerosis in South Asians Living in America studies without ASCVD. CAC was examined among those normoglycemic, pre-DM and DM. Logistic regression examined pre-DM and DM with the odds of any CAC > 0 and CAC ≥ 100. RESULTS: Among 7562 participants, CAC > 0 and CAC ≥ 100 in those with DM was highest in non-Hispanic White (NHW) (80% and 48%) and SA (72% and 41%) persons. Adjusted Ln (CAC + 1) was highest in NHW (3.68 ± 0.21) and SA (3.60 ± 0.23) (p < .01) DM patients. SA and NHW adults with DM (vs normoglycemic) had highest odds of CAC > 0 (2.13 and 2.27, respectively, p < .01). For CAC ≥ 100, SA and Chinese adults had the highest odds (2.28 and 2.27, respectively, p < .01). Fasting glucose and glycated hemoglobin were most strongly associated with CAC among SA. CONCLUSIONS: Diabetes mellitus most strongly relates to any CAC in SA and NHW adults and CAC ≥ 100 in SA and Chinese adults, helping to explain the relation of DM with ASCVD in these populations.

ABSTRACT

Little is known about food insecurity and the extent of Supplemental Nutrition Assistance Program (SNAP) participation in the heterogeneous Asian American population. Using California Health Interview Survey data from the period 2011-20, we examined both issues among low-income Asian American adults from six origin groups: Chinese, Filipino, Japanese, Korean, South Asian, and Vietnamese. We found high and varied levels of overall food insecurity, with the highest burden among Filipino adults (40 percent). Food insecurity by severity was also heterogenous; very low food security affected 2 percent of Chinese adults but 9 percent and 10 percent of Filipino and Japanese adults, respectively. Participation in CalFresh (California-implemented SNAP) ranged from 11 percent and 12 percent among Korean and Chinese adults, respectively, to 20 percent among Vietnamese adults. Compared with English-proficient low-income Asian American adults, those with limited English proficiency were no less likely to participate in CalFresh, possibly reflecting language assistance required by California law and provided by community-based organizations. These results underscore the importance of collecting and reporting disaggregated data by Asian origin group that could inform targeted outreach and interventions.

ABSTRACT

AIMS: We examined associations between lipoprotein subfractions and prevalent and incident T2D in two race/ethnically diverse cohort studies. METHODS: Adults self-identifying as White, Black, Chinese, Hispanic and South Asian-American without cardiovascular disease, with fasting serum, demographic, and clinical data at enrollment and after 5 years of follow-up were included. Lipoprotein subfractions were measured at enrollment using NMR spectrometry. LASSO regularized logistic regression models adjusted for age, sex, race/ethnicity, lipid-lowering agent use, and waist circumference assessed odds of incident T2D in pooled analyses. RESULTS: There were 4474 participants with lipoprotein subfraction data at enrollment and 3839 participants without prevalent diabetes, mean age 62 years, 51 % women, with 234 incident T2D cases at 5 years. Triglycerides in small, dense LDL-5 [OR 1.26 (95 % CI 1.11,1.43)], VLDL triglycerides 1.30** [1.16,1.46] and phospholipids in VLDL-1 [OR 1.31 (1.17,1.47)] were associated with higher odds of incident T2D, while free cholesterol in large HDL-1 [OR 0.75 (95 % CI 0.63,0.89)] was inversely associated. The results were similar for prevalent diabetes and did not vary by race/ethnic group. CONCLUSIONS: Composition of lipoprotein subfractions is differentially associated with prevalent and incident T2D without difference by race/ethnic group. Assessment of lipoprotein composition may enhance targeted risk reduction for T2D.

ABSTRACT

BACKGROUND: Children of South Asian (SA) origin in the UK have lower levels of physical activity (PA), compared to their White counterparts. Parents play an important role in establishing PA habits among young children. The aim of this study was to compare PA and television (TV) viewing parenting practices for young children between SA British (SAB) and White British (WB) parents living in the UK. METHODS: We conducted a secondary analysis of the Born in Bradford (BiB) 1000 study, using survey data at child ages 24 and 36 months. The study sample included three groups of mothers (n = 1,149): foreign-born SAB (n = 458), UK-born SAB (n = 276), and WB (n = 455). Mothers completed a survey about parenting practices (i.e., PA supports, PA restrictions, TV viewing restrictions) at child age 24 months and child PA and TV viewing behaviors at child ages 24 and 36 months. Parenting practices were compared among the three groups. Multivariable linear regression analyses compared children's weekly walking frequency and daily TV viewing hours by parenting practices in the three groups. RESULTS: The foreign-born SAB group showed the lowest frequencies of PA-supportive parenting practices (verbal encouragement: 3.7 ± 3.1 times/week; logistic support: 1.5 ± 1.8 times/week) and the highest frequencies of PA-restrictive parenting practices (7.8 ± 7.7 times/week) among the three groups (p < 0.01). Children of Foreign-born SAB mothers had the most frequent TV watching during a mealtime (4.0 ± 3.1 times/week) among the three groups (p < 0.01). Less frequent PA-supportive parenting practices and SA ethnicity were associated with lower walking frequency at 24 and 36 months of age among children (p < 0.01). More frequent exposure to TV at mealtimes and SA ethnicity were associated with higher TV viewing time at 24 and 36 months of age among children (p < 0.01). CONCLUSIONS: This study demonstrated that SAB parents, particularly those who are foreign-born, apply parenting practices for their young children that are less supportive of PA and more supportive of TV viewing, and their children have lower PA and higher TV viewing time, compared with their WB counterparts.

ABSTRACT

Objective: Assess trusted sources of information, perceived message effectiveness, and preferred dissemination strategies regarding adolescent HPV vaccination among U.S. Vietnamese parents. Methods: Data came from an observational, explanatory sequential mixed-methods study with U.S. Vietnamese parents of adolescents (408 survey participants; 32 interview participants). Surveys and interviews were conducted in both Vietnamese and English. Mixed-methods data were integrated and analyzed for confirmation, expansion, or discordance. Results: Both quantitative and qualitative findings confirm high trust in HPV vaccination information from providers, government agencies, and cancer organizations. Messages perceived as effective emphasize vaccine safety, experts' endorsement, importance of vaccination prior to HPV exposure, and preventable cancers. Qualitative findings expanded quantitative results, demonstrating a desire for evidence-based information in the Vietnamese language and addressing cultural concerns (e.g., effectiveness or potential side effects specific to Vietnamese adolescents, whether parents should delay HPV vaccination for Vietnamese adolescents). Quantitative and qualitative findings were incongruent about whether parents would trust information about HPV vaccination that is disseminated via social media. Conclusion: We identified credible messengers, feasible strategies, and elements of impactful messages for interventions to increase adolescent HPV vaccination for U.S. Vietnamese. Innovation: We focus on a high-risk, underserved population and integrate mixed-methods design and analysis.

ABSTRACT

We examined relationships between resilience resources (optimism, social support, and neighborhood social cohesion) and cardiovascular disease (CVD) incidence and assessed potential effect-measure modification by psychosocial risk factors (e.g., stress, depression) among adults without CVD in 3 cohort studies (2000-2018): the Jackson Heart Study, the Multi-Ethnic Study of Atherosclerosis, and the Mediators of Atherosclerosis in South Asians Living in America (MASALA) Study. We fitted adjusted Cox models accounting for within-neighborhood clustering while censoring at dropout or non-CVD death. We assessed for effect-measure modification by psychosocial risks. In secondary analyses, we estimated standardized risk ratios using inverse-probability-weighted Aalen-Johansen estimators to account for confounding, dropout, and competing risks (non-CVD deaths) and obtained 95% confidence intervals (CIs) using cluster bootstrapping. For high and medium (versus low) optimism (n = 6,243), adjusted hazard ratios (HRs) for incident CVD were 0.94 (95% CI: 0.78, 1.13) and 0.90 (95% CI: 0.75, 1.07), respectively. Corresponding HRs were 0.88 (95% CI: 0.74, 1.04) and 0.92 (95% CI: 0.79, 1.06) for social support (n = 7,729) and 1.10 (95% CI: 0.94, 1.29) and 0.99 (95% CI: 0.85, 1.16) for social cohesion (n = 7,557), respectively. Some psychosocial risks modified CVD HRs. Secondary analyses yielded similar findings. For optimism and social support, an inverse relationship was frequently most compatible with the data, but a positive relationship was also compatible. For neighborhood social cohesion, positive and null relationships were most compatible. Thus, specific resilience resources may be potential intervention targets, especially among certain subgroups.
