High blood pressure in Hispanics in the United States: a review

Food insecurity and the risk of mortality among Hispanics with hypertension

BACKGROUND AND AIMS

Hypertension continues to be a major public health problem affecting almost half of the adults in the US. The intersection of hypertension with food insecurity has not been well-examined specifically among minority populations. We aimed to examine the influence of food insecurity on mortality among adult Hispanics.

METHODS AND RESULTS

Data on adult Hispanic (age≥ 20 years) respondents of the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2010 were analyzed. Mortality was assessed by linking these data with the National Death Index through December 31, 2019. Using complex samples Cox regression analysis, the relationship between hypertension, food insecurity, and mortality was assessed. Sociodemographic (age, gender, poverty-income-ratio, marital status, and citizenship status) and health-related characteristics (COPD, diabetes, cardiovascular disease, chronic kidney disease) of the population were included as covariates in the regression analysis to assess mortality risk. The crude hazard ratio (HR) for overall mortality related to hypertension was 4.95 (95% confidence interval [CI] = 4.22-5.82, p < .001). The adjusted HR was elevated, 2.01 (95%CI = 1.50-2.70, p < .001), among individuals with both hypertension and food insecurity. However, among individuals with hypertension and no food insecurity, there was no statistically significant increase in the risk of mortality (HR = 1.09, 95%CI = 0.89-1.34, p > 0.05).

CONCLUSIONS

In adult Hispanics, food insecurity significantly increases the risk of mortality among those with hypertension compared to food-secure individuals. Clinicians should be sensitized to the need for food security among Hispanics with hypertension to effectively manage hypertension and reduce premature mortality.

Hypertension Prevalence among Hispanics/Latinos of Dominican Background: A Transnational Comparison of HCHS/SOL and ENPREFAR-HAS-17

Background

Hispanics/Latinos of Dominican background living in United States (US) have the highest hypertension prevalence compared with other Hispanic/Latino persons.

Objective

To understand cardiovascular health among Dominicans, we evaluated hypertension prevalence and risk factors among Dominicans from the US and Dominican Republic (DR) using data from Hispanic Community Health Study/ Study of Latinos [HCHS/SOL] and the Prevalencia de Hipertension Arterial y Factores de Riesgo Cardiovasculares en la República Dominicana al 2017 (ENPREFAR-HAS 17) study.

Methods

Hypertension was defined as blood pressure ≥140/90 mmHg, self-reported hypertension, or antihypertensive use. Exposures included sociodemographic/socioeconomic, clinical, and lifestyle/behavioral characteristics. Weighted generalized linear models were used to estimate associations between study characteristics and hypertension prevalence (PR = prevalence ratio), age-and-sex adjusted. HCHS/SOL (n = 1,473, US Dominicans; mean age 41 years, 60.4% female) was analyzed with survey procedures, while ENPREFAR-HAS 17 (n = 2,015 DR Dominicans; mean age 40 years, 50.3% female) was analyzed with statistical analyses for simple random sampling.

Results

Hypertension prevalence was 30.5% and 26.9% for DR and US Dominicans, respectively. Hypertension control was low in both cohorts (36.0% DR, 35.0% US). Alcohol use among DR Dominicans was inversely associated with hypertension prevalence (PRDR = 0.8) with no association among US Dominicans. In both settings, diabetes (PRDR = 1.4; PRUS = 1.4) and obesity (PRDR = 1.8; PRUS = 2.0) were associated with greater hypertension prevalence in Hispanics/Latinos of Dominican background. Physical activity was lower among US Dominicans (PR = 0.80) but higher among DR Dominicans (PR = 1.16); all p < 0.05.

Conclusions

Variations in social, lifestyle/behavioral, and clinical characteristics associated with hypertension among Dominicans in the US and DR were identified, suggesting that social context and cultural factors matter among immigrant populations.

Disparities in Healthcare-Seeking Behavior and Decision Preference Among Hispanics: A Comparative Study Across Races/Ethnicities, SES, and Provider Types

Purpose

Hispanics, the largest minority in America, have increased risk of several medical issues and face noteworthy health disparities. This study compares care-seeking behaviors and choice experience among Hispanics, Asians, Blacks, and Whites, considering SES (income, education, and insurance status) and across five healthcare provider (HCP) types. Concurrent analysis provides a comprehensive view of how and where inequity manifests in healthcare.

Methods

A cross-sectional online survey assessed 1485 adults (Hispanic=314, Asian=313, Black=316, White=542, recruited through a panel agency) of the frequency of visiting primary care providers, dentists, optometrists, gynecologists, and specialists for chronic conditions. Participants also rated the importance of self-selecting a HCP and difficulty in finding one.

Results

Whites visited each HCP most regularly. Compared to Asians, more Hispanics saw specialists regularly (45.1% vs 56.5%, p=0.042), and Blacks saw dentists less (47.0% vs 38.3%, p=0.028) and gynecologists more often (21.2% vs 33.1%, p=0.024). No other frequency differences were observed among minorities. Low-income participants across four races saw dentists and gynecologists with comparable infrequency. Hispanics and Asians assigned similarly significantly lower self-choice importance and experienced more difficulty relative to Whites or Blacks. Participants with lower income or education visited HCPs less regularly yet perceived the same choice importance as higher-SES peers (p>0.05). Notably, discrepancies in visit frequency between Whites and minorities were more pronounced in higher-SES than lower-SES group. Differences in experiencing care-seeking difficulty were associated with income (p=0.029) and insurance type (p=0.009) but not education (p>0.05).

Conclusion

Higher income and education increase healthcare utilization; however, racial disparities persist, particularly among higher-SES groups. Despite similarities among minorities, the extent of disparities varied by SES and provider type. The findings help explain evident inequity in healthcare access and health outcomes. Tailored patient education, culturally-specific navigation support, and more inclusive services are needed to address barriers faced by minorities and disadvantaged populations.

Latino-White Disparities in Identification and Control of Elevated Blood Pressure Among Adults With Hypertension

BACKGROUND

Studies analyzing blood pressure (BP) management using the hypertension control cascade have consistently shown disparities in hypertension awareness, treatment, and BP control between Latino patients and non-Latino White patients. We analyze this cascade using electronic health record data from a multistate network of community health centers.

METHODS AND RESULTS

Data from 790 clinics in 23 US states from 2012 to 2020, including 1 270 174 patients, were analyzed to compare BP documentation in the electronic health record, clinician acknowledgment (diagnosis or treatment) of incident hypertension (BP ≥140/90), medication prescription, and BP control between non-Latino White patients, English-preferring Latino patients, and Spanish-preferring Latino patients, adjusted for patient-level covariates, and clustered on patients' primary clinics. Among the 429 182 patients with elevated BP (≥140/90) during ambulatory visits from 2012 to 2020, we found that clinician acknowledgment of hypertension was more likely in Spanish-preferring and English-preferring Latino patients versus non-Latino White patients (adjusted odds ratio [aOR], 1.17 [95% CI, 1.11-1.24]; aOR, 1.07 [95% CI, 1.02-1.12], respectively). In addition, Spanish-preferring Latino patients were more likely to receive a medication versus non-Latino White patients (aOR, 1.21 [95% CI, 1.16-1.28]). Among those receiving medication, Latino patients were as likely as non-Latino White patients to have their BP controlled (<140/90).

CONCLUSIONS

In a large retrospective study of community health center patients with incident hypertension, the expected disparities in hypertension management between Spanish-preferring Latino, English-preferring Latino, and non-Latino White patients were not identified. These findings add to the hypertension control cascade by examining robust electronic health record data from community health centers and may provide clues to reducing disparities in hypertension management.

Association of PFDeA exposure with hypertension (NHANES, 2013-2018)

Perfluoroalkyl and polyfluoroalkyl substances (PFASs) is a series of artificial compounds which is associated with human health. However, there are few studies on the relationship between PFASs and hypertension. In this study, we examined the association between different kinds of PFASs and hypertension. Multivariable logistic regression and subgroup analysis were adopted to assess the associations between PFASs and hypertension. Spline smoothing plots and linear regression were used to assess the relationship between PFASs and blood pressure. We found a positive association between serum PFDeA concentrations and the prevalence of hypertension after fully adjusting confounders (OR = 1.2, P = 0.01), but other types of PFASs showed no positive results. Subgroup analysis stratified by ethnicity showed there was a stronger relationship among non-Hispanics than Hispanics. Serum PFDeA concentrations were positively associated with systolic pressure (β = 0.7, P< 0.01) and diastolic blood pressure (β = 0.8, P< 0.01) among non-Hispanics who did not take antihypertensive drugs. This study showed that PFDeA exposure was associated with hypertension in Americans who identify as non-Hispanic. There was a positive association between PFDeA and blood pressure in non-Hispanic Americans who did not take antihypertensive drugs.

Hypertension, Cognitive Decline, and Mild Cognitive Impairment Among Diverse Hispanics/Latinos: Study of Latinos-Investigation of Neurocognitive Aging Results (SOL-INCA)

BACKGROUND

Hypertension can have deleterious effects on cognitive function; however, few studies have examined its effects on cognition among Hispanics/Latinos.

OBJECTIVE

To assess associations between hypertension status with 1) change in cognitive performance, and 2) having mild cognitive impairment (MCI) among diverse Hispanics/Latinos.

METHODS

This population-based, prospective cohort, multisite study included Hispanic/Latino adults aged 45 to 72 years in enrolled in the Hispanic Community Health Study/Study of Latinos at Visit 1 (2008-2011; mean age of 63.40±8.24 years), and the Study of Latinos-Investigation of Neurocognitive Aging at Visit 2 (2016-2018), with a mean follow-up duration of 7 years (n = 6,173). Hypertension status was assessed at both visits: normotension (no hypertension), incident hypertension (only at Visit 2), and persistent hypertension (at both visits). We examined change in cognitive performance and having MCI (only assessed at Visit 2) relative to hypertension status and adjusted for demographics and cardiovascular disease risk factors.

RESULTS

Compared to normotension, persistent hypertension was associated with significantly increased decline in verbal fluency (β= -0.08; CI = [-0.16;-0.01]; p < 0.05), and processing speed (β= -0.11; CI = [-0.20;-0.02]; p < 0.05). Incident hypertension was not associated with significant change in cognitive performance. Both incident (OR = 1.70; CI = [1.16;2.50]; p < 0.01) and persistent hypertension (OR = 2.13; CI = [1.57;2.88]; p < 0.001) were associated with significantly higher odds ratios of having MCI.

CONCLUSIONS

These findings indicate that persistent hypertension is associated with clinical impairment and domain-specific cognitive decline in middle-aged and older Hispanics/Latinos. It underscores the importance of monitoring blood pressure in routine healthcare visits beginning at midlife in this population to reduce the burden of cognitive decline.

Prevalence and Correlates of Uncontrolled Hypertension, Persistently Uncontrolled Hypertension, and Hypertensive Crisis at a Healthcare System

BACKGROUND

Uncontrolled hypertension significantly increases risk of cardiovascular disease and death. This study examined the prevalence of uncontrolled hypertension, persistently uncontrolled hypertension, and hypertensive crisis and factors associated with these outcomes in a real-world patient cohort.

METHODS

Electronic medical records from a large healthcare system in North Carolina were used to identify adults with uncontrolled hypertension (last ambulatory blood pressure [BP] measurement ≥140/90); persistently uncontrolled hypertension (≥2 ambulatory BP measurements with all readings ≥140/90); and hypertensive crisis (any BP reading ≥180/120) in 2019. Generalized linear mixed models tested the association between patient and provider characteristics and each outcome.

RESULTS

The study cohort included 213,836 patients (mean age 63.1 (±14.0) years, 55.5% female, 70.8% white). Of these, 29.7% and 13.1% had uncontrolled hypertension and hypertensive crisis, respectively. Among those experiencing hypertensive crisis, >50% did not have uncontrolled hypertension. Of the 171,061 patients with ≥2 BP measurements, 5.9% had persistently uncontrolled hypertension. The likelihood of uncontrolled hypertension, persistently uncontrolled hypertension, and hypertensive crisis was higher in patients with black race (vs. white), self-pay (vs. private), prior emergency room visit, and no attributed primary care provider. Readings taken in the evening (vs. morning) and at specialty (vs. primary care) practices were more likely to meet thresholds for uncontrolled hypertension and hypertensive crisis.

CONCLUSIONS

Hypertension control remains a significant challenge in healthcare. Health systems may benefit from segmenting their patient population based on factors such as race, prior healthcare use, and timing of BP measurement to prioritize outreach and intervention.

Stress and DNA Methylation of Blood Leukocytes among Pregnant Latina Women

Latinas experience physical and psychological stressors in pregnancy leading to increased morbidity and higher risk for adverse birth outcomes. Epigenetic changes, including DNA methylation (DNAm), have been proposed as markers to create more refined risk stratification, yet few of these studies have examined these changes in Latinas. We conducted a secondary analysis of stored blood leukocytes of Latina women (n = 58) enrolled in a larger National Institutes of Health funded R01 project (2011-2016). We examined DNAm on eight candidate stress genes to compare physically and psychologically stressed participants to healthy (low stress) participants. We found unique CpGs that were differentially methylated in stressed women early- and mid-pregnancy compared to the healthy group, though none remained significant after FDR correction. Both physical and psychological stress were associated with hypomethylation at two consecutive CpG sites on NR3C1 in early pregnancy and one CpG site on NR3C1 in mid-pregnancy before adjustment. Stress was also associated with hypomethylation at two CpG sites on FKBP5 in early and mid-pregnancy but were no longer significant after FDR adjustment. Though we did not find statistically significant differences in DNAm during pregnancy between stressed and healthy women in this sample, signals were consistent with previous findings. Future work in larger samples should further examine the associations between stress and DNAm in pregnancy as this mechanism may explain underlying perinatal health inequities.

Implementation Strategies to Improve Blood Pressure Control in the United States: A Scientific Statement From the American Heart Association and American Medical Association

Hypertension is one of the most important risk factors that contribute to incident cardiovascular events. A multitude of US and international hypertension guidelines, scientific statements, and policy statements have recommended evidence-based approaches for hypertension management and improved blood pressure (BP) control. These recommendations are based largely on high-quality observational and randomized controlled trial data. However, recent published data demonstrate troubling temporal trends with declining BP control in the United States after decades of steady improvements. Therefore, there is a widening disconnect between what hypertension experts recommend and actual BP control in practice. This scientific statement provides information on the implementation strategies to optimize hypertension management and to improve BP control among adults in the United States. Key approaches include antiracism efforts, accurate BP measurement and increased use of self-measured BP monitoring, team-based care, implementation of policies and programs to facilitate lifestyle change, standardized treatment protocols using team-based care, improvement of medication acceptance and adherence, continuous quality improvement, financial strategies, and large-scale dissemination and implementation. Closing the gap between scientific evidence, expert recommendations, and achieving BP control, particularly among disproportionately affected populations, is urgently needed to improve cardiovascular health.

The ACTIVATE Digital Health Pilot Program for Diabetes and Hypertension in an Underserved and Rural Community

BACKGROUND

Community health centers and patients in rural and agricultural communities struggle to address diabetes and hypertension in the face of health disparities and technology barriers. The stark reality of these digital health disparities were highlighted during the coronavirus disease 2019 pandemic.

OBJECTIVES

The objective of the ACTIVATE (Accountability, Coordination, and Telehealth in the Valley to Achieve Transformation and Equity) project was to codesign a platform for remote patient monitoring and program for chronic illness management that would address these disparities and offer a solution that fit the needs and context of the community.

METHODS

ACTIVATE was a digital health intervention implemented in three phases: community codesign, feasibility assessment, and a pilot phase. Pre- and postintervention outcomes included regularly collected hemoglobin A1c (A1c) for participants with diabetes and blood pressure for those with hypertension.

RESULTS

Participants were adult patients with uncontrolled diabetes and/or hypertension (n = 50). Most were White and Hispanic or Latino (84%) with Spanish as a primary language (69%), and the mean age was 55. There was substantial adoption and use of the technology: over 10,000 glucose and blood pressure measures were transmitted using connected remote monitoring devices over a 6-month period. Participants with diabetes achieved a mean reduction in A1c of 3.28 percentage points (standard deviation [SD]: 2.81) at 3 months and 4.19 percentage points (SD: 2.69) at 6 months. The vast majority of patients achieved an A1c in the target range for control (7.0-8.0%). Participants with hypertension achieved reductions in systolic blood pressure of 14.81 mm Hg (SD: 21.40) at 3 months and 13.55 mm Hg (SD: 23.31) at 6 months, with smaller reductions in diastolic blood pressure. The majority of participants also reached target blood pressure (less than 130/80).

CONCLUSION

The ACTIVATE pilot demonstrated that a codesigned solution for remote patient monitoring and chronic illness management delivered by community health centers can overcome digital divide barriers and show positive health outcomes for rural and agricultural residents.

Longitudinal Analysis of Social Isolation and Cognitive Functioning among Hispanic Older Adults with Sensory Impairments

OBJECTIVES

Understanding the intersection of age, ethnicity, and disability will become increasingly important as the global population ages and becomes more diverse. By 2060, Hispanics will comprise 28% of the U.S.

POPULATION

This study examines critical associations between sensory impairment, social isolation, and cognitive functioning among Hispanic older adults.

METHODS

Our sample consisted of 557 Hispanic older adults that participated in Rounds 1-3 or Rounds 5-7 of the National Health and Aging Trends Study. Longitudinal mediation models across a three-year span were estimated using Mplus, with vision, hearing, and dual sensory impairments predicting cognitive functioning directly and indirectly through social isolation.

RESULTS

Findings indicated that cognitive functioning was concurrently and, in certain cases, longitudinally predicted by vision and dual sensory impairments and by social isolation. Contrary to expectations, vision and hearing impairments were not predictive of social isolation. Dual sensory impairment was associated with social isolation, yet no significant indirect associations were found for sensory impairments predicting cognitive functioning through social isolation.

DISCUSSION

The finding that social isolation did not mediate the relationship between sensory impairment and cognitive decline among Hispanic older adults in the U.S. is contrary to findings from other studies that were not specifically focused on this population. This finding may be evidence that culturally motivated family support and intergenerational living buffer the impact of sensory impairments in later life. Findings suggest that Hispanic older adults experiencing dual sensory impairments may benefit from interventions that foster social support and include family members.

The therapeutic concordance approach reduces adverse drug reactions in patients with resistant hypertension

Background

Adverse drug reactions (ADRs) remain among the leading causes of therapy-resistant hypertension (TRH) and uncontrolled blood pressure (BP). We have recently reported beneficial results in BP control in patients with TRH adopting an innovative approach, defined as therapeutic concordance, in which trained physicians and pharmacists reach a concordance with patients to make them more involved in the therapeutic decision-making process.

Methods

The main scope of this study was to investigate whether the therapeutic concordance approach could lead to a reduction in ADR occurrence in TRH patients. The study was performed in a large population of hypertensive subjects of the Campania Salute Network in Italy (ClinicalTrials.gov Identifier: NCT02211365).

Results

We enrolled 4,943 patients who were firstly followed-up for 77.64 ± 34.44 months, allowing us to identify 564 subjects with TRH. Then, 282 of these patients agreed to participate in an investigation to test the impact of the therapeutic concordance approach on ADRs. At the end of this investigation, which had a follow-up of 91.91 ± 54.7 months, 213 patients (75.5%) remained uncontrolled while 69 patients (24.5%, p < 0.0001) reached an optimal BP control. Strikingly, during the first follow-up, patients had complained of a total of 194 ADRs, with an occurrence rate of 68.1% and the therapeutic concordance approach significantly reduced ADRs to 72 (25.5%).

Conclusion

Our findings indicate that the therapeutic concordance approach significantly reduces ADRs in TRH patients.

Answering calls for rigorous health equity research: a cross-sectional study leveraging electronic health records for data disaggregation in Latinos

INTRODUCTION

Country of birth/nativity information may be crucial to understanding health equity in Latino populations and is routinely called for in health services literature assessing cardiovascular disease and risk, but is not thought to co-occur with longitudinal, objective health information such as that found in electronic health records (EHRs).

METHODS

We used a multistate network of community health centres to describe the extent to which country of birth is recorded in EHRs in Latinos, and to describe demographic features and cardiovascular risk profiles by country of birth. We compared geographical/demographic/clinical characteristics, from 2012 to 2020 (9 years of data), of 914 495 Latinos recorded as US-born, non-US-born and without a country of birth recorded. We also described the state in which these data were collected.

RESULTS

Country of birth was collected for 127 138 Latinos in 782 clinics in 22 states. Compared with those with a country of birth recorded, Latinos without this record were more often uninsured and less often preferred Spanish. While covariate adjusted prevalence of heart disease and risk factors were similar between the three groups, when results were disaggregated to five specific Latin countries (Mexico, Guatemala, Dominican Republic, Cuba, El Salvador), significant variation was observed, especially in diabetes, hypertension and hyperlipidaemia.

CONCLUSIONS

In a multistate network, thousands of non-US-born, US-born and patients without a country of birth recorded had differing demographic characteristics, but clinical variation was not observed until data was disaggregated into specific country of origin. State policies that enhance the safety of immigrant populations may enhance the collection of health equity related data. Rigorous and effective health equity research using Latino country of birth information paired with longitudinal healthcare information found in EHRs might have significant potential for aiding clinical and public health practice, but it depends on increased, widespread and accurate availability of this information, co-occurring with other robust demographic and clinical data nativity.

Clinical perspectives and strategies for confronting disparities in social determinants of health for Hispanic bilinguals with aphasia

Disparities in social determinants of health (SDOH) such as socioeconomic status and access to quality healthcare present serious barriers to enrollment in clinical rehabilitation programs for individuals who have experienced a stroke, especially for those who identify with a racial-ethnic minority group. Hispanic bilinguals with aphasia (HBWA) are one marginalized group who face even greater enrollment challenges since post-stroke language impairment and limited English proficiency make it difficult to advocate for one's needs and identify appropriate rehabilitation programs. Given the increasing representation of Hispanic individuals in the U.S. (projected to be 30% of the population in 2050), it is imperative that clinicians counter disparities in stroke care by facilitating access to clinical services for HBWA. However, the Hispanic population remains largely understudied in the stroke and aphasia literature, due in part to reduced opportunities to enroll in large-scale clinical research studies. In this paper we highlight how our team at Boston University has designed and implemented a variety of recruitment practices, assessment modifications, and treatment accommodations to circumvent the known barriers to participation in clinical research experienced by HBWA. Furthermore, we discuss the importance of cultural responsiveness and demonstrate how including principles of sensitivity and humility in clinical trial protocols improves participant enrollment and retention. Although clinical adjustments in this study were developed for use with HBWA, the effectiveness of the procedures suggests they may be useful blueprints for expanding access to research opportunities for various marginalized groups.

Hypertension and Diabetes Status by Patterns of Stress in Older Adults From the US Health and Retirement Study: A Latent Class Analysis

Background

Hypertension and diabetes disproportionately affect older non‐Hispanic Black and Hispanic adults in the United States. Chronic stress may partially explain these disparities. This study identified underlying stress profiles of older US adults, analyzed stress profiles in relation to hypertension and diabetes, examined the distribution of stress profiles by race and ethnicity, and assessed patterns of change in latent classes of stress over time.

Methods and Results

Latent class analysis was conducted with a nationally representative sample of older US adults who completed 3 waves of the HRS (Health and Retirement Study) (ie, 2010 [n=6863], 2014 [n=4995], and 2018 [n=3089]). Latent classes of stress in 2010 (ie, stress profiles) were identified using 15 indicators of unmet needs within 5 categories (ie, physiological, safety/security, belonging, esteem, and self‐fulfillment). Hypertension and diabetes status were examined as outcomes of latent class membership at 3 time points, and race and ethnicity were examined in association with class membership, adjusting for sociodemographic covariates. Finally, a latent transition analysis examined the stability of latent class membership and racial and ethnic differences in the patterns of stress profiles experienced from 2010 to 2018. Five classes were identified: Generally Unmet Needs (13% of sample), Generally Met Needs (42% of sample), Unmet Self‐Efficacy/Goal Needs (12% of sample), Unmet Financial Needs (20% of sample), and Unmet Social Belonging Needs (13% of sample). Compared with the Generally Met Needs class, the Generally Unmet Needs class had higher odds of hypertension (odds ratio [OR], 1.80; [95% CI, 1.35–2.39]) and diabetes (OR, 1.94; [95% CI, 1.45–2.59]), and the Unmet Financial Needs class had higher odds of diabetes (OR, 1.50; [95% CI, 1.10–2.05]). Non‐Hispanic Black participants compared with non‐Hispanic White participants had higher odds of being members of the Generally Unmet Needs, Unmet Self‐Efficacy/Goal Needs, and Unmet Financial Needs classes (OR, 2.70; [95% CI, 1.59–4.58]; OR, 1.99; [95% CI, 1.15–3.43]; and OR, 4.74; [95% CI, 3.32–6.76], respectively). Class membership remained relatively stable over time, with 93% of participants remaining in Generally Met Needs and 78% of participants remaining in Generally Unmet Needs across time points. Compared with non‐Hispanic White participants, non‐Hispanic Black participants had lower odds of Generally Met Needs class membership at any time point (OR, 0.60; [95% CI, 0.42–0.84]) and had lower odds of moving into the Generally Met Needs class and higher odds of moving into the Unmet Financial Needs class from 2010 to 2014 (OR, 0.33; [95% CI, 0.13–0.86]; and OR, 3.02; [95% CI, 1.16–7.87], respectively).

Conclusions

Underlying classes of stress based on unmet needs were associated with hypertension and diabetes status. Racial and ethnic differences were observed for both latent class membership and transitions between classes over time. Latent classes of stress associated with unmet needs, hypertension, and diabetes and the ability to transition between classes may explain the perpetuation of racial and ethnic disparities in cardiovascular health. Interventions targeting unmet needs may be used to confront these disparities.

Blood Pressure and Stroke: A Review of Sex- and Ethnic/Racial-Specific Attributes to the Epidemiology, Pathophysiology, and Management of Raised Blood Pressure

Raised blood pressure (BP) is the leading cause of death and disability worldwide, and its particular strong association with stroke is well established. Although systolic BP increases with age in both sexes, raised BP is more prevalent in males in early adulthood, overtaken by females at middle age, consistently across all ethnicities/races. However, there are clear regional differences on when females overtake males. Higher BP among males is observed until the seventh decade of life in high-income countries, compared with almost 3 decades earlier in low- and middle-income countries. Females and males tend to have different cardiovascular disease risk profiles, and many lifestyles also influence BP and cardiovascular disease in a sex-specific manner. Although no hypertension guidelines distinguish between sexes in BP thresholds to define or treat hypertension, observational evidence suggests that in terms of stroke risk, females would benefit from lower BP thresholds to the magnitude of 10 to 20 mm Hg. More randomized evidence is needed to determine if females have greater cardiovascular benefits from lowering BP and whether optimal BP is lower in females. Since 1990, the number of people with hypertension worldwide has doubled, with most of the increase occurring in low- and-middle-income countries where the greatest population growth was also seen. Sub-Saharan Africa, Oceania, and South Asia have the lowest detection, treatment, and control rates. High BP has a more significant effect on the burden of stroke among Black and Asian individuals than Whites, possibly attributable to differences in lifestyle, socioeconomic status, and health system resources. Although pharmacological therapy is recommended differently in local guidelines, recommendations on lifestyle modification are often very similar (salt restriction, increased potassium intake, reducing weight and alcohol, smoking cessation). This overall enhanced understanding of the sex- and ethnic/racial-specific attributes to BP motivates further scientific discovery to develop more effective prevention and treatment strategies to prevent stroke in high-risk populations.

Health Promotion Among Mexican-Origin Survivors of Breast Cancer and Caregivers Living in the United States-Mexico Border Region: Qualitative Analysis From the Vida Plena Study

Background

Hispanic survivors of cancer experience increased cancer burden. Lifestyle behaviors, including diet and physical activity, may reduce the cancer burden. There is limited knowledge about the posttreatment lifestyle experiences of Hispanic survivors of cancer living on the United States–Mexico border.

Objective

This study aims to support the development of a stakeholder-informed, culturally relevant, evidence-based lifestyle intervention for Mexican-origin Hispanic survivors of cancer living in a border community to improve their dietary quality and physical activity.

Methods

Semistructured interviews with 12 Mexican-origin Hispanic survivors of breast cancer and 7 caregivers were conducted through internet-based teleconferencing. The interviews explored the impact of cancer on lifestyle and treatment-related symptoms, perception of lifestyle as an influence on health after cancer, and intervention content and delivery preferences. Interviews were analyzed using a deductive thematic approach grounded in the Quality of Cancer Survivorship Care Framework.

Results

Key survivor themes included perception of Mexican diet as unhealthy, need for reliable diet-related information, perceived benefits of physical activity after cancer treatment, family support for healthy lifestyles (physical and emotional), presence of cancer-related symptoms interfering with lifestyle, and financial barriers to living a healthy lifestyle. Among caregivers, key themes included effects of the cancer caregiving experience on caregivers’ lifestyle and cancer-preventive behaviors and gratification in providing support to the survivors.

Conclusions

The interviews revealed key considerations to the adaptation, development, and implementation of a theory-informed, evidence-based, culturally relevant lifestyle program to support lifestyle behavior change among Mexican-origin Hispanic survivors of cancer living in border communities. Our qualitative findings highlight specific strategies that can be implemented in health promotion programming aimed at encouraging cancer protective behaviors to reduce the burden of cancer and comorbidities in Mexican-origin survivors of cancer living in border communities.

Blood Pressure and Later-Life Cognition in Hispanic and White Adults (BP-COG): A Pooled Cohort Analysis of ARIC, CARDIA, CHS, FOS, MESA, and NOMAS

BACKGROUND

Ethnic differences in cognitive decline have been reported. Whether they can be explained by differences in systolic blood pressure (SBP) is uncertain.

OBJECTIVE

Determine whether cumulative mean SBP levels explain differences in cognitive decline between Hispanic and White individuals.

METHODS

Pooled cohort study of individual participant data from six cohorts (1971-2017). The present study reports results on SBP and cognition among Hispanic and White individuals. Outcomes were changes in global cognition (GC) (primary), executive function (EF) (secondary), and memory standardized as t-scores (mean [SD], 50 [10]); a 1-point difference represents a 0.1 SD difference in cognition. Median follow-up was 7.7 (Q1-Q3, 5.2-20.1) years.

RESULTS

We included 24,570 participants free of stroke and dementia: 2,475 Hispanic individuals (median age, cumulative mean SBP at first cognitive assessment, 67 years, 132.5 mmHg; 40.8% men) and 22,095 White individuals (60 years,134 mmHg; 47.3% men). Hispanic individuals had slower declines in GC, EF, and memory than White individuals when all six cohorts were examined. Two cohorts recruited Hispanic individuals by design. In a sensitivity analysis, Hispanic individuals in these cohorts had faster decline in GC, similar decline in EF, and slower decline in memory than White individuals. Higher time-varying cumulative mean SBP was associated with faster declines in GC, EF, and memory in all analyses. After adjusting for time-varying cumulative mean SBP, differences in cognitive slopes between Hispanic and White individuals did not change.

CONCLUSION

We found no evidence that cumulative mean SBP differences explained differences in cognitive decline between Hispanic and White individuals.

Impact of Amerind ancestry and FADS genetic variation on omega-3 deficiency and cardiometabolic traits in Hispanic populations

Long chain polyunsaturated fatty acids (LC-PUFAs) have critical signaling roles that regulate dyslipidemia and inflammation. Genetic variation in the FADS gene cluster accounts for a large portion of interindividual differences in circulating and tissue levels of LC-PUFAs, with the genotypes most strongly predictive of low LC-PUFA levels at strikingly higher frequencies in Amerind ancestry populations. In this study, we examined relationships between genetic ancestry and FADS variation in 1102 Hispanic American participants from the Multi-Ethnic Study of Atherosclerosis. We demonstrate strong negative associations between Amerind genetic ancestry and LC-PUFA levels. The FADS rs174537 single nucleotide polymorphism (SNP) accounted for much of the AI ancestry effect on LC-PUFAs, especially for low levels of n-3 LC-PUFAs. Rs174537 was also strongly associated with several metabolic, inflammatory and anthropomorphic traits including circulating triglycerides (TGs) and E-selectin in MESA Hispanics. Our study demonstrates that Amerind ancestry provides a useful and readily available tool to identify individuals most likely to have FADS-related n-3 LC-PUFA deficiencies and associated cardiovascular risk.

Global interventions in hypertension: new and emerging concepts

PURPOSE OF REVIEW

Hypertension (HTN) is the most prevalent risk factor for cardiovascular disease (CVD) worldwide, affecting 1.39 billion people. This review discusses recent literature regarding the global burden of HTN and emerging concepts in prevalence, treatment, and control in different regions around the globe.

RECENT FINDINGS

Community-based interventions and telemedicine may be useful in increasing access to care and identifying/assisting patients with HTN, especially in populations with geographical and economic barriers to healthcare. Home blood pressure monitoring is beneficial for HTN control in diverse regions. Polypills have proven benefits to decrease HTN and CVD risk. Continuation of treatment with angiotensin-converting-enzyme inhibitors and angiotensin-receptor blockers in high risk COVID-19 patients appears appropriate.

SUMMARY

Extensive research demonstrates that early screening/treatment, lifestyle modification, and pharmacotherapy are essential to control HTN worldwide. This review highlights recent research and novel concepts on effective interventions being used globally.

Toward a fine-scale population health monitoring system

Understanding population health disparities is an essential component of equitable precision health efforts. Epidemiology research often relies on definitions of race and ethnicity, but these population labels may not adequately capture disease burdens and environmental factors impacting specific sub-populations. Here, we propose a framework for repurposing data from electronic health records (EHRs) in concert with genomic data to explore the demographic ties that can impact disease burdens. Using data from a diverse biobank in New York City, we identified 17 communities sharing recent genetic ancestry. We observed 1,177 health outcomes that were statistically associated with a specific group and demonstrated significant differences in the segregation of genetic variants contributing to Mendelian diseases. We also demonstrated that fine-scale population structure can impact the prediction of complex disease risk within groups. This work reinforces the utility of linking genomic data to EHRs and provides a framework toward fine-scale monitoring of population health.

Air pollution exposure is linked with methylation of immunoregulatory genes, altered immune cell profiles, and increased blood pressure in children

Ambient air pollution exposure is associated with cardiovascular dysregulation and immune system alterations, yet no study has investigated both simultaneously in children. Understanding the multifaceted impacts may provide early clues for clinical intervention prior to actual disease presentation. We therefore determined the associations between exposure to multiple air pollutants and both immunological outcomes (methylation and protein expression of immune cell types associated with immune regulation) and cardiovascular outcomes (blood pressure) in a cohort of school-aged children (6–8 years; n = 221) living in a city with known elevated pollution levels. Exposure to fine particular matter (PM_2.5), carbon monoxide (CO), and ozone (O₃) was linked to altered methylation of most CpG sites for genes Foxp3, IL-4, IL-10 and IFN-g, all involved in immune regulation (e.g. higher PM_2.5 exposure 1 month prior to the study visit was independently associated with methylation of the IL-4 CpG24 site (est = 0.16; P = 0.0095). Also, immune T helper cell types (Th1, Th2 and Th17) were associated with short-term exposure to PM_2.5, O₃ and CO (e.g. Th1 cells associated with PM_2.5 at 30 days: est = − 0.34, P < 0.0001). Both B cells (est = − 0.19) and CD4+ cells (est = 0.16) were associated with 1 day NO2 exposure (P ≤ 0.031), whereas CD4+ and CD8+ cells were associated with chronic exposure to PAH₄₅₆, NOx and/or NO₂ (P ≤ 0.038 for all). Finally, diastolic BP (DBP) was inversely associated with long-term exposures to both CO and PAH₄₅₆, and both systolic and pulse pressure were associated with short-term NO₂ and chronic NOx exposure. Our findings demonstrate links between air pollution exposure and methylation of immunoregulatory genes, immune cell profiles and blood pressure, suggesting that even at a young age, the immune and cardiovascular systems are negatively impacted by exposure to air pollution.
