Background: Asian people in the United States have different sociodemographic and health-related characteristics that might affect cardiovascular disease (CVD) risk by ethnicity and birthplace. However, they are often studied as a monolithic group in health care research. This study aimed to examine heterogeneity in CVD risk factors on the basis of birthplace among the 3 largest Asian subgroups (Chinese, Asian Indian, and Filipino) compared with US-born non-Hispanic White (NHW) adults., Methods and Results: A cross-sectional analysis was conducted using the 2010 to 2018 National Health Interview Survey data from 125 008 US-born and foreign-born Chinese, Asian Indian, Filipino, and US-born NHW adults. Generalized linear models with Poisson distribution were used to examine the prevalence and prevalence ratios of self-reported hypertension, diabetes, high cholesterol, physical inactivity, smoking, and overweight/obesity among Asian subgroups compared with US-born NHW adults. The study included 118 979 US-born NHW and 6029 Asian adults who self-identified as Chinese (29%), Asian Indian (33%), and Filipino (38%). Participants' mean (±SD) age was 49±0.1 years, and 53% were females. In an adjusted analysis, foreign-born Asian Indians had significantly higher prevalence of diabetes, physical inactivity, and overweight/obesity; foreign-born Chinese had higher prevalence of physical inactivity, and foreign-born Filipinos had higher prevalence of all 5 CVD risk factors except smoking compared with NHW adults., Conclusions: This study revealed significant heterogeneity in the prevalence of CVD risk factors among Asian subgroups by ethnicity and birthplace, stressing the necessity of disaggregating Asian subgroup data. Providers should consider this heterogeneity in CVD risk factors and establish tailored CVD prevention plans for Asian subgroups.

Background In the United States, Black adults have higher rates of cardiovascular disease (CVD) risk factors than White adults. However, it is unclear how CVD risk factors compare between Black ethnic subgroups, including African Americans (AAs), African immigrants (AIs), and Afro-Caribbeans, and White people. Our objective was to examine trends in CVD risk factors among 3 Black ethnic subgroups and White adults between 2010 and 2018. Methods and Results A comparative analysis of the National Health Interview Survey was conducted among 452 997 participants, examining sociodemographic characteristics and trends in 4 self-reported CVD risk factors (hypertension, diabetes, overweight/obesity, and smoking). Generalized linear models with Poisson distribution were used to obtain predictive probabilities of the CVD risk factors. The sample included 82 635 Black (89% AAs, 5% AIs, and 6% Afro-Caribbeans) and 370 362 White adults. AIs were the youngest, most educated, and least insured group. AIs had the lowest age- and sex-adjusted prevalence of all 4 CVD risk factors. AAs had the highest prevalence of hypertension (2018: 41.9%) compared with the other groups. Overweight/obesity and diabetes prevalence increased in AAs and White adults from 2010 to 2018 ( P values for trend <0.001). Smoking prevalence was highest among AAs and White adults, but decreased significantly in these groups between 2010 and 2018 ( P values for trend <0.001), as compared with AIs and Afro-Caribbeans. Conclusions We observed significant heterogeneity in CVD risk factors among 3 Black ethnic subgroups compared with White adults. There were disparities (among AAs) and advantages (among AIs and Afro-Caribbeans) in CVD risk factors, suggesting that race alone does not account for disparities in CVD risk factors.

Objective: To examine the association between social determinants of health, hypertension, and diabetes among African immigrants., Methods: The African Immigrant Health Study was a cross-sectional study of the health of African immigrants in the Baltimore-Washington Metropolitan Area. The outcomes of interest were self-reported diagnoses of hypertension and diabetes. Logistic regression was used to examine the relationship between educational status, employment, income, social support, health insurance, and self-reported diagnoses of hypertension and diabetes, adjusting for age, sex, and length of stay in the U.S., Results: A total of 465 participants with mean (±SD) age 47 (±11.5) years were included. Sixty percent were women, 64% had a college degree or higher, 83% were employed, 67% had health insurance, and 70% were married/cohabitating. Over half (60%) of the participants had lived in the United States for ≥ 10 years, and 84% were overweight/obese. The overall prevalence of hypertension and diabetes was 32% and 13%, respectively. The odds of diabetes was higher (aOR: 5.00, 95% CI: 2.13, 11.11) among those who were unemployed than among those who were employed, and the odds of hypertension was higher among those who had health insurance (aOR:1.73, 95% CI: 1.00, 3.00) than among those who did not., Conclusions: Among African immigrants, those who were unemployed had a higher likelihood of a self-reported diagnosis of diabetes than those who were employed. Also, people who had health insurance were more likely to self-report a diagnosis of hypertension. Additional studies are needed to further understand the influence of social determinants of health on hypertension and diabetes to develop health policies and interventions to improve the cardiovascular health of African immigrants.

In recent decades, the number of African immigrants in high-income countries (HICs) has increased significantly. However, the cardiometabolic health of this population remains poorly examined. Thus, we conducted a systematic review to examine the prevalence of cardiometabolic risk factors among sub-Saharan African immigrants residing in HICs. Studies were identified through searches in electronic databases including PubMed, Embase, CINAHL, Cochrane, Scopus, and Web of Science up to July 2021. Data on the prevalence of cardiometabolic risk factors were extracted and synthesized in a narrative format, and a meta-analysis of pooled proportions was also conducted. Of 8655 unique records, 35 articles that reported data on the specific African countries of origin of African immigrants were included in the review. We observed heterogeneity in the burden of cardiometabolic risk factors by African country of origin and HIC. The most prevalent risk factors were hypertension (27%, range: 6-55%), overweight/obesity (59%, range: 13-91%), and dyslipidemia (29%, range: 11-77.2%). The pooled prevalence of diabetes was 11% (range: 5-17%), and 7% (range: 0.7-14.8%) for smoking. Few studies examined kidney disease, hyperlipidemia, and diagnosed cardiometabolic disease. Policy changes and effective interventions are needed to improve the cardiometabolic health of African immigrants, improve care access and utilization, and advance health equity.

Objective: This study sought to assess the association between unidimensional acculturation and diabetes, and analyze mediating pathways of the association in African immigrants to the United States (U.S.). Hypothesis : Acculturation would be positively associated with diabetes and that BMI (Body mass index), physical activity, and psychological distress would mediate this association. Methods: An analysis of cross-sectional data from the 2010-2017 National Health Interview Surveys was performed. Adults aged ≥ 18 years who were born in Africa (African immigrants) and residing in the U.S. were considered. The outcome was self-reported diabetes, and acculturation was defined by percent of life spent in the U.S. and citizenship. Multivariable logistic regression analysis was used to assess the association between acculturation and diabetes, and mediation analysis was used to examine the mediating effects of BMI, physical activity, and psychological distress on this association. Results: The analytic sample included 1648 African immigrants with mean (SD) age of 41.3 ± 0.45 years; 56.4% male. Additionally, 46% had ≥ college education, and 21.4% lived below the poverty threshold. About two-thirds were overweight/obese. Less than 50% exercised at adequate levels of physical activity levels. A small percentage (1.8%) reported psychological distress. The prevalence of self-reported diabetes was 6.1%, and 76.5% reported being acculturated. In the multivariate logistic regression analysis, higher levels of acculturation were associated with higher odds of diabetes diagnosis (Odds Ratio (OR) = 2.2; 95% CI = 1.1-4.4). Although BMI mediated the association between acculturation and diabetes ( Z M e d i a t i o n  = 2.11, p  = 0.036), only 18.9% of the total effect of acculturation on diabetes was explained by BMI. Conclusions: Acculturation increased the odds of diabetes diagnosis, and BMI mediated the association. Thus, tailoring culturally-appropriate interventions to control BMI may contribute to preventing diabetes within African immigrant communities to the U.S.

Acculturation and immigration-related factors may impact preventive, routine cardiovascular risk (CV) screening among African immigrants. We examined the associations between length of stay, percent of life spent in the U.S. (proxy for acculturation), and CV screening. Outcomes were recent screening for hypertension, diabetes, and dyslipidemia. Multivariable logistic regression analyses were used to examine these relationships. Among 437 African immigrants, 60% were males, mean age was 47 years, 61% had lived in the U.S. for ≥10 years, mean length of stay was 15 years, and 81% were employed. Only 67% were insured. In the 12 months prior, 85% had screened for hypertension, 45% for diabetes, and 63% for dyslipidemia. African immigrants with a ≥10-year length of U.S. stay had 2.20 (95%Confidence Intervals: 1.31−3.67), and those with >25% years of life spent in the U.S. had 3.62 (95%CI: 1.96−6.68) higher odds of dyslipidemia screening compared to those with a <10-year length of stay and ≤25% years of life spent in the U.S., respectively. Overall, screening for CV risk higher in African immigrants who have lived longer (≥10 years) in the U.S. Recent African immigrants may experience challenges in accessing healthcare. Health policies targeting recent and uninsured African immigrants may improve access to CV screening services.

In the United States (U.S.), Blacks have higher morbidity and mortality from cardiovascular disease (CVD) than other racial groups. The Black racial group includes African Americans (AAs), African immigrants (AIs), and Afro-Caribbeans (ACs); however, little research examines how social determinants differentially influence CVD risk factors in each ethnic subgroup. We analyzed the 2010-2014 National Health Interview Survey, a cross-sectional, nationally representative survey of non-institutionalized civilians. We included 40,838 Blacks: 36,881 AAs, 1660 AIs, and 2297 ACs. Age- and sex-adjusted hypertension prevalence was 37, 22, and 21% in AAs, ACs, and AIs, respectively. Age- and sex-adjusted diabetes prevalence was 12, 10, and 7% in AAs, ACs, and AIs, respectively. In the multivariable logistic regression analyses, social determinants of hypertension and diabetes differed by ethnicity. Higher income was associated with lower odds of hypertension in AAs (aOR 0.86, 95% CI 0.77-0.96) and ACs (aOR 0.55, 95% CI 0.37-0.83). In AAs, those with some college education (aOR 0.79, 95% CI 0.68-0.92) and college graduates (aOR 0.62, 95% CI 0.53-0.73) had lower odds of hypertension than those with < high school education. In AIs, having health insurance was associated with higher odds of hypertension (aOR 1.59, 95% CI 1.04-2.42) and diabetes (aOR 3.22, 95% CI 1.29-8.04) diagnoses. We observed that the social determinants associated with hypertension and diabetes differed by ethnicity. Socioeconomic factors of health insurance and income were associated with a disparate prevalence of hypertension by ethnic group. Future research among Blacks should stratify by ethnicity to adequately address the contributors to health disparities.

Background: Ethnic minority populations in the United States (US) are disproportionately affected by cardiovascular disease (CVD) risk factors, including hypertension, overweight/obesity, and diabetes. The size and diversity of ethnic minority immigrant populations in the US have increased substantially over the past three decades. However, most studies on immigrants in the US are limited to Asians and Hispanics; only a few have examined the prevalence of CVD risk factors across diverse immigrant populations. The prevalence of diagnosed hypertension, overweight/obesity, and diagnosed diabetes was examined and contrasted among a socioeconomically diverse sample of immigrants. It was hypothesized that considerable variability would exist in the prevalence of hypertension, overweight and diabetes., Methods: A cross-sectional analysis of the 2010-2016 National Health Interview Survey (NHIS) was conducted among 41,717 immigrants born in Europe, South America, Mexico/Central America/Caribbean, Russia, Africa, Middle East, Indian subcontinent, Asia and Southeast Asia. The outcomes were the prevalence of diagnosed hypertension, overweight/obesity, and diagnosed diabetes., Results: The highest multivariable adjusted prevalence of diagnosed hypertension was observed in Russian (24.2%) and Southeast Asian immigrants (23.5%). Immigrants from Mexico/Central America/Caribbean and the Indian subcontinent had the highest prevalence of overweight/obesity (71.5 and 73.4%, respectively) and diagnosed diabetes (9.6 and 10.1%, respectively). Compared to European immigrants, immigrants from Mexico/Central America/Caribbean and the Indian subcontinent respectively had higher prevalence of overweight/obesity (Prevalence Ratio (PR): 1.19[95% CI, 1.13-1.24]) and (PR: 1.22[95% CI, 1.14-1.29]), and diabetes (PR: 1.70[95% CI, 1.42-2.03]) and (PR: 1.78[95% CI, 1.36-2.32]). African immigrants and Middle Eastern immigrants had a higher prevalence of diabetes (PR: 1.41[95% CI, 1.01-1.96]) and PR: 1.57(95% CI: 1.09-2.25), respectively, than European immigrants -without a corresponding higher prevalence of overweight/obesity., Conclusions: Immigrants from Mexico/Central America/Caribbean and the Indian subcontinent bore the highest burden of overweight/obesity and diabetes while those from Southeast Asia and Russia bore the highest burden of hypertension.

Background: Cardiometabolic risk (CMR) factors including hypertension, overweight/obesity, diabetes mellitus, and hyperlipidemia are high among United States ethnic minorities, and the immigrant population continues to burgeon., Methods and Results: Hypothesizing that acculturation (length of residence) would be associated with a higher prevalence of CMR factors, the authors analyzed data on 54, 984 US immigrants in the 2010-2014 National Health Interview Surveys. The main predictor was length of residence. The outcomes were hypertension, overweight/obesity, diabetes mellitus, and hyperlipidemia. The authors used multivariable logistic regression to examine the association between length of US residence and these CMR factors.The mean (SE) age of the patients was 43 (0.12) years and half were women. Participants residing in the United States for ≥10 years were more likely to have health insurance than those with <10 years of residence (70% versus 54%, P<0.001). After adjusting for region of birth, poverty income ratio, age, and sex, immigrants residing in the United States for ≥10 years were more likely to be overweight/obese (odds ratio [OR], 1.19; 95% CI, 1.10-1.29), diabetic (OR, 1.43; 95% CI, 1.17-1.73), and hypertensive (OR, 1.18; 95% CI, 1.05-1.32) than those residing in the United States for <10 years., Conclusions: In an ethnically diverse sample of US immigrants, acculturation was associated with CMR factors. Culturally tailored public health strategies should be developed in US immigrant populations to reduce CMR., (© 2016 The Authors.

In the 20th century, Africans in Sub-Saharan Africa had lower rates of cardiometabolic disease than Africans who migrated. However, in the 21st century, beyond infectious diseases, the triple epidemics of obesity, diabetes and hypertension have taken hold in Africa. Therefore, Africans are acquiring these chronic diseases at different rates and different intensity prior to migration. To ensure optimal care and health outcomes, the United States practice of grouping all African-descent populations into the "Black/African American" category without regard to country of origin masks socioeconomic and cultural differences and needs re-evaluation. Overall, research on African-descent populations would benefit from a shift from a racial to an ethnic perspective. To demonstrate the value of disaggregating data on African-descent populations, the epidemiologic transition, social, economic, and health characteristics of African immigrants are presented.
