“…Overall, members of this community have much higher obesity (50.9% BMI ≥30, 9.0% BMI ≥40) and T2D rates (28.0%) versus the average American population (35.7% BMI ≥30, 6.3% BMI ≥40, T2D 8.3%) [36-38]. These statistics reflect the general trend of Mexican Americans living along the entire US-Mexico border [27]. Participants in this study were slightly heavier but had lower T2D rates than the CCHC as a whole (60% BMI ≥30, 12.9% T2D).…”

“…Americans of Mexican descent (MAm) are at an increased risk of obesity and T2D compared to all Americans (Am) nationally (MAm 39.1% BMI ≥30, T2D 12.8%) (Am 35.7% BMI ≥30, T2D 8.3%) [25-27]. Diabetes in Hispanics occurs earlier (mean age of diagnosis 49.4 years for Hispanics, 53.8 years for all Americans), manifests with higher complication rates, and attacks at nearly twice the rate of non-Hispanic whites (WAm) (T2D 12.8% MAm, T2D 7.6% WAm [28]).…”

BackgroundObesity and type 2 diabetes (T2D) are major public health concerns worldwide, and their prevalence has only increased in recent years. Mexican Americans are disproportionately afflicted by obesity and T2D, and rates are even higher in the United States-Mexico border region. To determine the factors associated with the increased risk of T2D, obesity, and other diseases in this population, the Cameron County Hispanic Cohort was established in 2004.ResultsIn this study, we characterized the 16S gut community of a subset of 63 subjects from this unique cohort. We found that these communities, when compared to Human Microbiome Project subjects, exhibit community shifts often observed in obese and T2D individuals in published studies. We also examined microbial network relationships between operational taxonomic units (OTUs) in the Cameron County Hispanic Cohort (CCHC) and three additional datasets. We identified a group of seven genera that form a tightly interconnected network present in all four tested datasets, dominated by butyrate producers, which are often increased in obese individuals while being depleted in T2D patients.ConclusionsThrough a combination of increased disease prevalence and relatively high gut microbial homogeneity in the subset of CCHC members we examined, we believe that the CCHC may represent an ideal community to dissect mechanisms underlying the role of the gut microbiome in human health and disease. The lack of CCHC subject gut community segregation based on all tested metadata suggests that the community structure we observe in the CCHC likely occurs early in life, and endures. This persistent ‘disease’-related gut microbial community in CCHC subjects may enhance existing genetic or lifestyle predispositions to the prevalent diseases of the CCHC, leading to increased attack rates of obesity, T2D, non-alcoholic fatty liver disease, and others.Electronic supplementary materialThe online version of this article (doi:10.1186/s40168-015-0072-y) contains supplementary material, which is available to authorized users.

“…Diabetes mortality and prevalence rates for border Hispanic adults are 2 to 3 times higher than for non-Hispanic whites. 3,4 In the border region known as the Rio Grande Valley in South Texas, where this study was conducted, diabetes prevalence among aging Hispanics (28%) is higher than the national level (18%), as well as other US areas with large Hispanic populations including San Antonio (24%) and Houston (21%) in Texas, and San Diego (17%) in California (E. Moy, unpublished data, Hispanic Elders Community Chartbook, 2007). Studies also show that older Hispanics in the Rio Grande Valley receive less diabetes education and clinical testing, and fewer eye examinations than their non-Hispanic white counterparts (E. Moy, unpublished data, Hispanic Elders Community Chartbook, 2007).…”

Little is known about predictors of health care utilization for older Hispanics with chronic conditions. This study aimed to determine: (1) the level of health care access for older Hispanics with type 2 diabetes living in a US-Mexico border area; and (2) personal and health correlates to health care utilization (ie, physician visits, eye care, emergency room [ER] use). This was a cross-sectional study based on a community assessment conducted at a clinic, senior centers, and colonias. Colonias are impoverished neighborhoods with substandard living conditions along the US-Mexico border. Hispanics living in colonias are one of the most disadvantaged minority groups in the United States. The study sample consisted of 249 Hispanics age 60 years and older who have type 2 diabetes. Descriptive analyses, multiple linear regression, and generalized linear models were conducted. Older age (P = 0.02) and affordability of physician fees (P = 0.02) were significant correlates to more frequent physician visits. Factors significantly associated with eye care were being insured (P = 0.001) and reporting high cholesterol (P = 0.005). ER use was significantly associated with younger age (60-64 years old; P = 0.03) and suffering from hypertension (P = 0.02). Those who received diabetes education (P = 0.04) were less likely to use the ER. Identifying patterns of health care utilization services in aging underserved minorities who are disproportionately affected by diabetes may lead to culturally appropriate preventive practices and timely access to health care. Adequate health care access can decrease or delay the onset of diabetes complications in older Hispanics with type 2 diabetes who live along the US-Mexico border.

PURPOSE Peer support can promote diabetes control, yet research on feasible and effective peer support models is lacking. This randomized controlled trial tested a volunteer-based model of peer support for diabetes control.METHODS Thirty-four volunteer peer leaders were recruited and trained to provide support to 5 to 8 patients each through telephone contact, in-person, individual, and group support. Planned dose was 8 contacts, preferably in the first 6 months. Patients with uncontrolled diabetes were randomly sampled from the medical records of 3 community clinics. After a baseline interview and medical records review to obtain baseline values for the primary outcome, HbA 1c , 336 patient participants were randomly assigned to a 12-month peer support intervention or usual care. The assessment protocol was repeated at 6 and 12 months after baseline. RESULTSThirty peer leaders delivered an average of 4 contacts each per assigned participant (range 1-24). Despite the lack of intervention fidelity, the intervention was effective at reducing glycated hemoglobin (HbA 1c ) among intervention as compared with usual care participants (P=0.05). Similar trends were observed in frequency of meeting fruit and vegetable guidelines (P =0.09), a secondary outcome. Counterintuitively, usual care participants reported checking their feet more days out of 7 than intervention participants (P =0.03).CONCLUSIONS Given the modest changes we observed, combined with other evidence for peer support to promote diabetes control, additional research is needed on how to modify the system of care to increase the level of peer support delivered by volunteers.Ann Fam Med 2015;13(Suppl_1):S9-S17. doi: 10.1370/afm.1807.

INTRODUCTION D iabetes is prevalent in the United3 Health care use remains low in rural border communities, 4,5 and health care is underused for managing diabetes. 6,7 Research is needed on how to promote glycemic control in rural border communities.Controlling diabetes requires engaging in healthy behaviors such as exercise, self-monitoring, controlling symptoms, and using medication and health care properly. 8 An educator, potentially a peer leader, 9,10 can help persons with diabetes develop the necessary skills to make these behaviors part of their daily lives. In Latino and other racial/ethnic and low-income communities, community health workers (CHWs) often serve as educators and peer leaders, facilitating access to health care, training in selfmanagement behaviors, and providing emotional support. 9,[11][12][13][14][15][16][17][18][19] CHWs are typically members of the communities they serve and have direct or indirect experience with the health issue of interest.11 Most CHW interventions with Latinos to promote diabetes control have involved paid CHWs serving in various roles within a health care system or a community-...
