Objective: To determine the prevalence of obesity and metabolic syndrome (MS) in the population older than 45 years in rural Western Honduras and contribute to the limited literature on MS in Central America.

Methods: Descriptive cross-sectional study conducted in the District of Copan. The study includes 382 men and women aged 45 to 75 years. With proper consent, anthropometric parameters, blood pressure, blood sugar, and lipid profile were evaluated. MS was diagnosed by using the National Cholesterol Education Program Criteria - Adult Panel Treatment III (NCEP-ATP III). Data were stored in REDCap (Research Electronic Data Capture) and analyzed with STATA14.

Results: Data were collected on 382 patients; of these, 38% were male and 62% female. The prevalence of obesity was 24.1% for both sexes. The prevalence of MS was 64.9%. Prevalence in males and females was 54% and 71%, respectively. Notable parameters were elevated triglycerides (71%), low High-density lipoprotein cholesterol (HDL-C) (63.4%), and abdominal obesity (56.8%). In men, the distribution of MS was more homogeneous, with a mean result of 80% amongst all ages.

Conclusions: The overall prevalence of obesity and MS is severely underestimated in rural Honduras. The most remarkable parameter for MS was high triglycerides (71%). Sixty-nine percent of the population has above-normal Body Mass Index (BMI). Public health efforts to control comorbidities and tackle risk factors in this population should take utmost priority.

Introduction: Pragmatic clinical trials (PCTs) are designed to connect researchers with clinicians to assess the real-world effectiveness and feasibility of interventions, treatments, or health care delivery strategies in routine practice. Within PCTs larger, more representative sampling is possible to improve the external validity of the research. Older adults from underrepresented groups can benefit from PCTs given their historically lower engagement in clinical research. The current article focuses on older Hispanic adults with Alzheimer disease and related dementias (ADRDs). Older Hispanic adults represent 19% of the US population and have a higher prevalence of ADRDs than Whites. We provide data from 2 PCTs about the recruitment of older Hispanics with ADRDs and discuss unique challenges associated with conducting PCTs and propose strategies to overcome challenges.

Data and methods: The first PCT outlined is the Patient Priorities Care for Hispanics with Dementia (PPC-HD) trial. PPC-HD is testing the feasibility of implementing a culturally adapted version of the Patient Priorities Care approach for older Hispanic adults with multiple chronic conditions and dementia. The second PCT is the Dementia Care (D-CARE) Study, which is a multisite pragmatic study comparing the effectiveness of a health care system-based approach and a community-based approach to dementia care to usual care in patients with ADRDs and their family caregivers.

Lessons learned and recommendations for future studies: The lessons learned are summarized according to the various stakeholders that need to work together to effectively recruit diverse participants for PCTs: individuals, health care systems, research teams, and communities. Individual-level considerations include communication, priorities, and flexibility. Health care system-level considerations are grounded in 4 principles of Community-Based Participatory Research and include collaboration/partnership, available resources, priorities of the health care system, and sustainability. Research team-level considerations include team members, intentionality, and communication. Community-level considerations highlight the importance of partnerships, community members, and appropriate incentives.

Discussion: PCTs provide a unique and potentially impactful opportunity to test interventions in real-world settings that must be culturally appropriate to reach underrepresented groups. Collectively, considering variables at multiple levels to address the needs of older adults with ADRDs is crucial, and the examples and suggestions provided in this report are a foundation for future research.

Introduction: In recent years, premature "deaths of despair" (ie, due to alcohol, drug use, and suicide) among middle-aged White Americans have received increased attention in the popular press, yet there has been less discussion on what explains premature deaths among young African Americans. In this study, we examined factors related to deaths of despair (alcohol use, drug use, smoking) and contextual factors (perceived discrimination, socioeconomic status, neighborhood conditions) as predictors of premature deaths before the age of 65 years among African Americans.

Methods: The Jackson Heart Study (JHS) is a longitudinal cohort study of African Americans in the Jackson, Mississippi, metropolitan statistical area. We included participants younger than 65 years at baseline (n=4000). Participant enrollment began in 2000 and data for these analyses were collected through 2019. To examine predictors of mortality, we calculated multivariable adjusted hazard ratios (HRs; 95% CI), using Cox proportional hazard models adjusted for age, sex, ideal cardiovascular health metrics, drug use, alcohol intake, functional status, cancer, chronic kidney disease, asthma, waist circumference, depression, income, education, health insurance status, perceived neighborhood safety, and exposure to lifetime discrimination.

Results: There were 230 deaths in our cohort, which spanned from 2001-2019. After adjusting for all covariates, males (HR, 1.50; 95% CI, 1.11-2.03), participants who used drugs (HR, 1.53; 95% CI, 1.13-2.08), had a heavy alcohol drinking episode (HR, 1.71; 95% CI, 1.22-2.41), reported 0-1 ideal cardiovascular health metrics (HR, 1.78; 95% CI, 1.06-3.02), had cancer (HR, 2.38; 95% CI, 1.41-4.01), had poor functional status (HR, 1.68; 95% CI, 1.19-2.37), or with annual family income less than $25,000 (HR, 1.63; 95% CI, 1.02-2.62) were more likely to die before 65 years of age.

Conclusions: In our large cohort of African American men and women, clinical predictors of premature death included poor cardiovascular health and cancer, and social predictors included low income, drug use, heavy alcohol use, and being a current smoker. Clinical and social interventions are warranted to prevent premature mortality in African Americans.

Purpose: Hypertension, obesity, hyperlipidemia, and type 2 diabetes contribute primarily to noncommunicable disease deaths and together with human immunodeficiency virus contribute largely to mortality in South Africa. Our longitudinal study provides the necessary data and insights over a 10-year period to highlight the areas where improved management is required in urban and rural localities.

Methods: This study included 536 rural and 387 urban Black participants aged 32 to 93 years from the North-West province, South Africa. Disease prevalence, treatment, and control were determined in 2005 and were re-evaluated in 2015. Multiple measures analyses were used to determine the trends of blood pressure and waist circumference.

Results: The initial prevalence of hypertension was 53.2%, obesity was 23.6%, hyperlipidemia was 5.1%, diabetes was 2.9%, and human immunodeficiency virus was 10.7% in 2005. By 2015, the rural population had higher rates of hypertension (63.7% versus 58.5%) and lower rates diabetes (4.3% versus 7.9%) and hyperlipidemia (6.6% versus 18.0%) with similar obesity rates (41.7% versus 42.4%). The average blood pressure levels of urban hypertensives decreased (P_trend<.001), whereas levels were maintained in the rural group (P_trend=.52). In both locations, treatment and control rates increased from 2005 to 2015 for all conditions (all ≥6.7%), except for diabetes in which a decrease in control was observed. Waist circumference increased (P_trend>.001) in both sex and locality groups over the 10-year period.

Conclusion: Although average blood pressure of urban hypertensive individuals decreased, urgent measures focused on early identification, treatment, and control of the respective conditions should be implemented to decrease the burden of noncommunicable diseases.

Introduction: Immigration has been identified as an important social determinant of health (SDH), embodying structures and policies that reinforce positions of poverty, stress, and limited social and economic mobility. In the public health literature with regard to diet, immigration is often characterized as an individual-level process (dietary acculturation) and is largely examined in one racial/ethnic subgroup at a time. For this narrative review, we aim to broaden the research discussion by describing SDH common to the immigrant experience and that may serve as barriers to healthy diets.

Methods: A narrative review of peer-reviewed quantitative, qualitative, and mixed methods studies on cardiometabolic health disparities, diet, and immigration was conducted.

Results: Cardiometabolic disease disparities were frequently described by racial/ethnic subgroups instead of country of origin. While cardiovascular disease and obesity risk differed by country of origin, diabetes prevalence was typically higher for immigrant groups vs United States (US)-born individuals. Common barriers to achieving a healthy diet were food insecurity; lack of familiarity with US food procurement practices, food preparation methods, and dietary guidelines; lack of familiarity and distrust of US food processing and storage methods; alternative priorities for food purchasing (eg, freshness, cultural relevance); logistical obstacles (eg, transportation); stress; and ethnic identity maintenance.

Conclusions: To improve the health of immigrant populations, understanding similarities in cardiometabolic health disparities, diet, and barriers to health across immigrant communities-traversing racial/ethnic subgroups-may serve as a useful framework. This framework can guide research, policy, and public health practices to be more cohesive, generalizable, and meaningfully inclusive.

Scholars have been interested in the relationship between skin tone and health since at least the 1970s; however, no study, to our knowledge, has analyzed a diverse immigrant sample. In this study, we use the New Immigrant Survey and interactions to examine how skin tone and race/ethnicity - alongside gender - jointly pattern BMI among Legal Permanent Residents. Our approach allows for the analysis of BMI among multiple racial/ethnic immigrant groups, while considering skin tone. Our results document that darker skin shades are associated with higher BMI, but only for women. Further, we also tease out the relationship between gender and race/ethnicity for BMI, which allows us to better understand this critical connection for new immigrants' health in the United States. Together, our results highlight that BMI jointly varies by skin tone and race/ethnicity, which emphasizes the importance of an intersectional approach, especially for new immigrant women of color.

In 2020, the highest rates of cervical cancer incidence and mortality were reported in Asian and African regions of the world. Across the globe, growing evidence confirms cancer disparities among racial and ethnic minorities, low socioeconomic status groups, sexual and gender minorities, uninsured individuals, and rural residents. Recognition of these stark disparities has led to increased global efforts for improving screening rates overall and, in medically underserved populations, highlighting the urgent need for research to inform the successful implementation of cervical cancer screening. Implementation science, defined as the study of methods to promote the integration of research evidence into health care practice, is well-suited to address this challenge. With a multilevel, implementation focus, we present key research directions that can help address cancer disparities in resource-limited settings. First, we describe several global feasibility studies that acknowledge the effectiveness of self-sampling as a strategy to improve screening coverage. Second, we highlight Project ECHO as a strategy to improve providers' knowledge through an extended virtual learning community, thereby building capacity for health care settings to deliver screening. Third, we consider community health workers, who are a cornerstone of implementing public health interventions in global communities. Finally, we see tremendous learning opportunities that use contextually relevant strategies to advance the science of community engagement and adaptations that could further enhance the uptake of screening in resource-limited settings. These opportunities provide future directions for bidirectional exchange of knowledge between local and global resource-limited settings to advance implementation science and address disparities.

Harmful algal blooms (HABs) are a significant global environmental management challenge, especially with respect to microalgae that produce dangerous natural toxins. Examples of HAB toxin diseases with major global health impact include: ciguatera poisoning, paralytic shellfish poisoning (PSP), amnesic shellfish poisoning (ASP), diarrhetic shellfish poisoning (DSP), and neurotoxic (brevetoxin) shellfish poisoning (NSP). Such diseases affect communities globally and contribute to health inequalities within the United States and beyond. Sharing data and lessons learned about the factors determining bloom occurrence and associated exposure to contaminated seafood across locations can reduce public health risks. Knowledge sharing is particularly important as ongoing global environmental changes seem to alter the intensity, location, and timing of toxic HAB events, reducing the reliability of conventional guidance where toxin risks have been endemic and leading to emerging challenges in new settings. Political changes that disrupt membership in knowledge-sharing networks may impede efforts to share scientific expertise and best practices. In this commentary, we stress the importance of community and expert knowledge sharing for reducing HAB risks, both for vulnerable communities in the United States and globally. Considering the impacts of political changes, we note the indirect engagement sometimes required for continued participation in international coordination programs. As an example, we highlight how lessons learned from a Native-led toxin monitoring and testing program (the Southeast Alaska Tribal Ocean Research partnership) can inform programs in other settings. We also describe how international knowledge is mutually valuable for this program in Southeast Alaska.

Background: Rates of severe maternal morbidity and maternal mortality (SMM/MM) in the United States are rising. Disparities in SMM/MM persist by race, ethnicity and geography, and could partially be attributed to social determinants of health.

Purpose: Utilizing data from the largest, statewide referral hospital in Alabama, we investigated the relationship between residence in disadvantaged neighborhoods and SMM/MM.

Methods: Data on all pregnancies between 2010 and 2020 were included; SMM/MM cases were identified using CDC definitions. Area deprivation index (ADI) available at the census-block group was geographically linked to individual records and categorized using quintile cutoffs; higher ADI score indicated higher socioeconomic disadvantage. Generalized estimating equation models were used to adjust for spatial autocorrelation and ORs were computed to evaluate the relationship between ADI and SMM/MM, adjusted for covariates including age, race, insurance, residence in medically underserved areas/population (MUAP), and urban/rural residence.

Results: Overall, 32,909 live-birth deliveries were identified, with a prevalence of 9.8% deliveries with SMM/MM with blood transfusion and 5.3% without blood transfusion, respectively. Increased levels of ADI were associated with increased odds of SMM/MM. Compared to women in the lowest quintile, the adjusted OR for SMM/MM among women in highest quintile was 1.78 (95%CI, 1.22-2.59, P=.0027); increasing age, non-Hispanic Black, government insurance and residence in MUAP were also significantly associated with increased odds of SMM/MM.

Conclusion: Our results suggest that residence within disadvantaged neighborhoods may contribute to SMM/MM even after adjusting for patient-level factors. Measures such as ADI can help identify the most vulnerable populations and provide points to intervene.
