Addressing Neurocognitive Disorders, Dementias, and Alzheimer's Disease in Colonias of the Lower Rio Grande Valley: Establishing a Research Foundation Using Promotores

Burden of Diabetes Mellitus in the Medically Underserved Rio Grande Valley

Introduction Diabetes mellitus (DM) encompasses metabolic disorders characterized by elevated blood sugar. This study aimed to evaluate the prevalence and associated metrics of DM in the Rio Grande Valley (RGV), a low-income and medically underserved region in the United States, and compare these metrics to the national averages from 2012 to 2022. Methods  A retrospective cross-sectional analysis was conducted using publicly accessible data from the Centers for Medicare and Medicaid Services (CMS). Metrics analyzed included DM prevalence, average principal cost, rates of emergency department visits, hospitalizations, screenings, and prevalence of obesity. Data from the RGV counties were compared to national averages using Mann-Whitney U tests, with a p-value of <0.05 considered significant. Results From 2012 to 2022, DM affected patients in the RGV (43.95%) at significantly higher rates than the national average (26.73%) (p < 0.001). Obesity prevalence in the RGV was at higher rates than the national average (24.41% vs. 15.55%, p < 0.01). The screening rates of DM exceeded the national average (10.64% vs. 5.09%, p < 0.001). The average principal cost for patients in the RGV ($1,920.45) to treat DM was significantly greater than the national average principal cost ($859.64) (p < 0.001). The RGV also reported higher rates of ED visits (16.82 vs. 8.82 per 1,000 beneficiaries, p < 0.001) and hospitalizations (7.75 vs. 3.82 per 1,000 beneficiaries, p < 0.001). Conclusion The RGV exhibits significantly higher rates of DM and DM-associated metrics compared to the national averages, highlighting substantial public health disparities.

Bridging Bone Health: Osteoporosis Disparities in the Rio Grande Valley

INTRODUCTION

Osteoporosis is characterized by decreased bone mass and decreased bone quality, leading to increased bone fragility and risk of fractures. The number of fractures due to osteoporosis is projected to increase to over three million by the year 2025 and cost $25.3 billion annually. It ranks highly among diseases that cause patients to become bedridden with serious complications and reduced quality of life. Additionally, osteoporosis disproportionately affects Hispanics, which comprise most of the Rio Grande Valley (RGV) population. Therefore, our primary objective was to determine the prevalence of osteoporosis within the RGV. Additionally, we had secondary objectives to determine the screening rates of osteoporosis in the RGV and identify other potential risk factors associated with osteoporosis. We hypothesize that individuals residing in the RGV have higher rates of osteoporosis and lower rates of osteoporosis screening than the national average.

METHODS

This retrospective observational cross-sectional study utilized Medicare beneficiary data via the "Mapping Medicare Disparities by Population" interactive tool. Osteoporosis data were compared within the RGV (comprising Starr, Hidalgo, Cameron, and Willacy counties) and compared with national averages between the years 2016 and 2021. Statistical analysis included prevalence ratios with 95% confidence intervals and chi-square values when applicable.

RESULTS

Among Medicare beneficiaries residing in the RGV, there are higher rates of osteoporosis compared to the national average (11.5% vs. 7.20%; p < .00001). Screening for osteoporosis within the RGV is above the national average (9.29% vs. 6.67%, p < .00001). Hispanics residing in the RGV have higher overall rates of osteoporosis than Caucasians residing in the RGV (12.3% vs. 8.60%, p < .00001). Females residing in the RGV have nearly twice the rate of osteoporosis compared to the national average (19.1% vs. 11.8%, p < .00001) and 6.58 times the rate of males residing in the RGV (19.1% vs. 2.9%, p < .00001).

CONCLUSION

Individuals residing in the RGV are disproportionately affected by osteoporosis. Despite increased screening rates seen among Medicare beneficiaries, we also suspect many individuals, uninsured or undocumented, have not received any appropriate osteoporosis screening. Risk factors in the RGV associated with higher rates of osteoporosis could include low education levels, socioeconomic status, physical activity, and mineral intake. These results demonstrate a need to address osteoporosis health literacy, promote earlier interventions to treat osteoporosis and increase healthcare accessibility in the RGV.

Variations in racial and ethnic groups' trust in researchers associated with willingness to participate in research

Low enrollment in U.S. biomedical research by non-White adults has historically been attributed to mistrust, but few studies have simultaneously examined dimensions of trust in three or more racial/ethnic groups. Leveraging the racial/ethnic diversity of New Jersey, we prospectively recruited 293 adults (72% women, 38% older than 54 years of age) between October 2020 and February 2022 to complete two anonymous surveys in English or one of the common languages (e.g., Spanish, Mandarin Chinese). The first consisted of 12 Likert Scale questions related to trust in biomedical researchers (according to safety, equity, transparency), and the second assessed willingness to consider participation in eight common research activities (health-related survey, blood collection, genetic analysis, medication study, etc). Participants self-reported as Hispanic (n=102), Black (n=49), Chinese (n=48), other Asian (n=53), or White (n=41) race/ethnicity. Factor analysis showed three aspects related to trust in researchers: researchers as fiduciaries for research participants, racial/ethnic equity in research, and transparency. Importantly, we observed differences in the relationship between mistrust and willingness to participate. Whereas Chinese respondents' low trust in researchers mediated their low interest in research involving more than health-related surveys, Hispanic respondents' low trust in research equity did not deter high willingness to participate in research involving blood and genetic analysis. We caution that a generic association between trust and research participation should not be broadly assumed, and biomedical researchers should prospectively assess this relationship within each minoritized group to avoid hasty generalization.

Design, implementation, and evaluation of community health worker training programs in Latinx communities: A scoping review

This review examines the current reporting trends of program design, implementation, and evaluation of training programs for Latinx community health workers. Five scholarly databases were searched using a scoping review methodology to identify articles describing training programs for Latinx community health workers. The timeframe was 2009 to 2021. We identified 273 articles, with 59 meeting inclusion criteria. Researchers thematically coded the articles to identify reporting strategies related to program design, implementation, and evaluation. Findings suggest a lack of consensus in reporting elements critical to program resources, instructor qualifications, frequency and length of training implementation, theoretical background, and pedagogical tools associated with the training program. We offer detailed reporting recommendations of community health worker training programs to support the consistent dissemination of promising practices and facilitate the initiation of new programs for Latinx community health workers.
