Costs and Projected Effect of a Federally Qualified Health Center-Based Mailed Colorectal Cancer Screening Program in Texas.

Introduction: Mailed stool testing for colorectal cancer (CRC) may improve screening uptake and reduce the incidence and mortality of CRC, especially among patients at federally qualified health centers (FQHCs). To expand screening programs it is important to identify cost-effective approaches. Methods: We developed a decision-analytic model to estimate the cost, effects on screening and patient outcomes (CRCs detected, CRCs prevented, CRC deaths prevented), and cost-effectiveness of implementing a state-wide mailed stool testing program over 5 years among unscreened, age-eligible (aged 50-75 y) patients at FQHCs in Texas. We compared various outreach strategies and organizational structures (centralized, regional, or a hybrid). We used data from our existing regional mailed stool testing program and recent systematic reviews to set parameters for the model. Costs included start-up and ongoing activities and were estimated in 2022 US dollars from the perspective of a hypothetical third-party payer. Cost-effectiveness was assessed by using both incremental and average cost-effectiveness ratios. Results: Using either a statewide centralized or hybrid organizational configuration to mail stool tests to newly eligible FQHC patients and patients who have responded at least once since program inception is likely to result in the best use of resources over 5 years, enabling more than 110,000 additional screens, detecting an incremental 181 to 194 CRCs, preventing 91 to 98 CRCs, and averting 46 to 50 CRC deaths, at a cost of $10 million to $11 million compared with no program. Conclusions: A statewide mailed stool testing program for FQHC patients can be implemented at reasonable cost with considerable effects on CRC screening outcomes, especially when its structure maximizes program efficiency while maintaining effectiveness.

Implementation and Evaluation of a Large Community-Based Colorectal Cancer Screening Program.

CONTEXT: Colorectal cancer (CRC) screening can significantly reduce incidence and mortality; however, screening rates are suboptimal. The lowest rates are among those with no usual source of care and the uninsured. OBJECTIVE: We describe the implementation and evaluation of a community-based CRC screening program from 2012 to 2015 designed to increase screening within a predominantly Hispanic US-Mexico border population. METHODS: The multicomponent, evidence-based program provided in-person, bilingual, culturally tailored health education facilitated by community health workers, no-cost primarily stool-based testing and diagnostic colonoscopy, and navigation. We recruited uninsured individuals due for CRC screening from clinics and community sites. An extensive qualitative and quantitative program process and outcome evaluation was conducted. RESULTS: In total, 20 118 individuals were approached, 8361 were eligible for screening; 74.8% completed screening and 74.6% completed diagnostic testing; 14 cancers were diagnosed. The mean age of participants was 56.8 years, and the majority were Hispanic, female, and of low socioeconomic status. The process evaluation gathered information that enabled effective program implementation and demonstrated effective staff training, compliance with processes, and high patient satisfaction. CONCLUSIONS: This program used a population-based approach focusing on uninsured individuals and proved successful at achieving high fecal immunochemical test kit return rates and colonoscopy completion rates. Key factors related to its success included tailoring the intervention to our priority population, strong partnerships with community-based sites and clinics, expertise in clinical CRC screening, and an active community advisory board. This program can serve as a model for similar populations along the border to increase CRC screening rates among the underserved.

Evaluating the persuasiveness of messages promoting mobile mammography among uninsured women.

Mobile mammography units (MMUs) can enhance access to breast cancer screening by providing convenient, cost-effective service, particularly for uninsured and underinsured women. However, prior studies indicate that acceptability concerns about quality and privacy, among other issues, may prevent women from utilizing MMUs. The current study employs a within-participant experimental design exposing participants to messages about different MMU characteristics to determine which characteristics are most effective in persuading them to use an MMU. The study also examined how messaging interacts with participants' ethnic identity to influence outcomes. Data were collected from a diverse sample of uninsured and underinsured women as part of a formative study to promote the utilization of a mobile mammography facility in Central Texas. Results of mixed-effect linear models show that messages about equity, appointment convenience, privacy and comfort, and quality of equipment and staff were rated as more persuasive than messages about convenience of location and language accessibility. However, Hispanic women rated language accessibility higher than other participants did. The results can guide MMU organizers and promotion managers as they determine the best approach to promote mobile mammography services in different communities.

Implementing a mailed stool sample screening program in clinics providing care for an underserved Hispanic population.

Colorectal cancer (CRC) is a leading cause of cancer-related deaths in Hispanics in the US. Despite this, Hispanics are being screened for CRC at a much lower rate than their non-Hispanic white counterparts. Implementing mailed fecal immunochemical tests (FITs) is a cost-effective intervention for increasing CRC screening rates in vulnerable populations, such as Hispanic populations in border metroplexes. We aimed to describe the effect of introductory calls coupled with mailed in-home FIT kits on CRC screening completion in two federally qualified health centers (FQHCs) in a US-Mexico border county. This was a prospective, pragmatic, two-arm intervention study with participants allocated to receive a FIT kit with a reminder call (usual care) or usual care preceded by an introductory call. The primary outcome was the percentage of patients who returned the FIT kits. Participants who returned to the FIT were primarily unemployed (54.4%), had less than a high school education (60.2%), lived in the US for at least 20 years (74.4%), and had poor self-reported health (54.4%). In addition, we observed a statistically significant increase in the absolute rate (4.5%, P = 0.003) of FITs returned when a mailed FIT kit was preceded by an introductory call compared with no initial call. This study demonstrated that adding an introductory phone call significantly improved the screening completion rate in a mailed-out CRC screening intervention in the US-Mexico border population.

Psychosocial Risk Profiles and Colorectal Cancer Screening: A Latent Profile Analysis in a Colorectal Cancer Screening Intervention Setting.

Health behavior theories have identified predictors of colorectal cancer screening. This study aimed to determine the psychosocial profiles of a predominantly Hispanic population of primarily Mexican origin receiving a colorectal cancer screening intervention and whether a specific combination of psychosocial profiles modified the effect of colorectal cancer screening intervention on colorectal cancer screening uptake.A total of 467 participants aged 50 to 75 years due for colorectal cancer screening received an educational intervention. Latent profile analysis (LPA) was performed on baseline psychosocial constructs to identify the homogenous clustering of individuals with similar psychosocial constructs. In addition, colorectal cancer screening rates and changes in psychosocial scores between the latent groups were compared.Three psychosocial profiles, including a low benefit and high susceptibility group (LBHS), a high benefit and low susceptibility group (HBLS), and a high barrier and high susceptibility group (HBHS), were identified in this study. The HBLS group had the lowest susceptibility, with no improvement in benefits and barriers. This group had the lowest screening rate (80.85%) compared with 88.8% in LBHS and 86.3% in HBHS following the intervention. Finally, the intervention effect size on psychosocial score changes was smaller in HBLS than in other groups.This subgroup analysis suggests that colorectal cancer educational interventions should be tailored to improve the benefits and barriers among individuals with high susceptibility scores. PREVENTION RELEVANCE: This LPA analysis provides some direction for tailoring colorectal cancer educational interventions to improve the benefits and barriers among individuals with high susceptibility scores in hard-to-screen populations such as our border population.

Understanding the role of access in Hispanic cancer screening disparities.

BACKGROUND: Hispanic populations in the United States experience numerous barriers to care access. It is unclear how cancer screening disparities between Hispanic and non-Hispanic White individuals are explained by access to care, including having a usual source of care and health insurance coverage. METHODS: A secondary analysis of the 2019 National Health Interview Survey was conducted and included respondents who were sex- and age-eligible for cervical (n = 8316), breast (n = 6025), or colorectal cancer screening (n = 11,313). The proportion of ever screened and up to date for each screening type was compared.  Regression models evaluated whether controlling for reporting a usual source of care and type of health insurance (public, private, none) attenuated disparities between Hispanics and non-Hispanic White individuals. RESULTS: Hispanic individuals were less likely than non-Hispanic White individuals to be up to date with cervical cancer screening (71.6% vs. 74.6%) and colorectal cancer screening (52.9% vs. 70.3%), but up-to-date screening was similar for breast cancer (78.8% vs. 76.3%). Hispanic individuals (vs. non-Hispanic White) were less likely to have a usual source of care (77.9% vs. 86.0%) and more likely to be uninsured (23.6% vs. 7.1%). In regressions, insurance fully attenuated cervical cancer disparities. Controlling for both usual source of care and insurance type explained approximately half of the colorectal cancer screening disparities (adjusted risk difference: -8.3 [-11.2 to -4.8]). CONCLUSION: Addressing the high rate of uninsurance among Hispanic individuals could mitigate cancer screening disparities. Future research should build on the relative successes of breast cancer screening and investigate additional barriers for colorectal cancer screening. PLAIN LANGUAGE SUMMARY: This study uses data from a national survey to compare cancer screening use those who identify as Hispanic with those who identify as non-Hispanic White. Those who identify as Hispanic are much less likely to be up to date with colorectal cancer screening than those who identify as non-Hispanic White, slightly less likely to be up to date on cervical cancer screening, and similarly likely to receive breast cancer screening. Improving insurance coverage is important for health equity, as is further exploring what drives higher use of breast cancer screening and lower use of colorectal cancer screening.

Colorectal neoplasia prevalence in a predominantly Hispanic community: Results from a colorectal cancer screening program in Texas.

BACKGROUND: A community-based, colorectal cancer (CRC) screening program for uninsured/underinsured individuals was successfully implemented in El Paso, Texas to increase CRC screening rates. Our aim was to determine the colorectal neoplasia prevalence among program participants and between screening groups. METHODS: We retrospectively reviewed participant records from 2012 to 2017. Average-risk patients were first screened with a fecal immunochemical test (FIT) and included if positive. Above average-risk patients due to a family history of CRC were referred directly for screening colonoscopy. Patients were excluded if experiencing melena or hematochezia or had a personal history of colon polyps or CRC. RESULTS: Of the 638 screening colonoscopies performed, 59.4% were in FIT-positive subjects and 40.6% were in subjects with a family history of CRC. Patients were predominantly female (72.9%), aged 50-65 years (84.2%), Hispanic (97.9%), and born in Mexico (92.4%). Overall, the detection rate for polyps, adenomas, and advanced adenomas was 46.2%, 34.3%, and 11.1%, respectively. Fifteen patients had adenocarcinoma (2.4%). Compared with colonoscopies in patients with a family history, FIT-positive patients demonstrated a higher prevalence of polyps (PR 1.39, 95% CI 1.09-1.78), adenomas (PR 1.55, 95% CI 1.15-2.07), advanced adenomas (PR 3.04, 95% CI 1.67-5.56). CONCLUSIONS: This community-based CRC screening program in an enriched cohort of predominantly Mexican Americans was effective in identifying colorectal neoplasia and cancer. Additionally, there was an increased prevalence of colorectal neoplasia in average-risk, FIT-positive patients undergoing screening colonoscopy compared with above average-risk patients with a family history of CRC. Similar screening programs would likely benefit at-risk populations.

Mediators of screening uptake in a colorectal cancer screening intervention among Hispanics.

BACKGROUND: Colorectal cancer (CRC) is the second leading cause of cancer deaths in the USA. Although a number of CRC screening tests have been established as being effective for CRC prevention and early detection, rates of CRC screening test completion in the US population remain suboptimal, especially among the uninsured, recent immigrants and Hispanics. In this study, we used a structural equation modelling approach to identify factors influencing screening test completion in a successful CRC screening program that was implemented in an uninsured Hispanic population. This information will enhance our understanding of influences on CRC screening among historically underscreened populations. METHODS: We used generalized structural equation models (SEM) utilizing participant reported information collected through a series of surveys. We identified direct and indirect pathways through which cofactors, CRC knowledge and individual Health Belief Model constructs (perceived benefits, barriers, susceptibility, fatalism and self-efficacy) and a latent psychosocial health construct mediated screening in an effective prospective randomized CRC screening intervention that was tailored for uninsured Hispanic Americans. RESULTS: Seven hundred twenty-three participants were eligible for inclusion; mean age was 56 years, 79.7% were female, and 98.9% were Hispanic. The total intervention effect was comparable in both models, with both having a direct and indirect effect on screening completion (n = 715, Model 1: RC = 2.46 [95% CI: 2.20, 2.71, p < 0.001]; n = 699, Model 2 RC =2.45, [95% CI: 2.18, 2.72, p < 0.001]. In Model 1, 32% of the overall effect was mediated by the latent psychosocial health construct (RC = 0.79, p < 0.001) that was in turn mainly influenced by self-efficacy, perceived benefits and fatalism. In Model 2, the most important individual mediators were self-efficacy (RC = 0.24, p = 0.013), and fatalism (RC = 0.07, p = 0.033). CONCLUSION: This study contributes to our understanding of mediators of CRC screening and suggests that targeting self-efficacy, perceived benefits and fatalism could maximize the effectiveness of CRC screening interventions particularly in Hispanic populations.

Evaluation of a Narrative Video to Promote Prevention and Early Detection of Cervical Cancer Among Latinas.

OBJECTIVE: To evaluate the impact of an online-delivered, theory-based narrative video on cervical cancer screening knowledge, attitudes, and beliefs in a predominantly Latino community. METHODS: The study design was a nonrandomized pretest-posttest evaluation. The eligibility criteria included men and women 18 years or older not previously enrolled in our community cervical cancer screening program who had internet access. Participants were recruited via in-person county-wide flyer distribution and social media dissemination. The intervention involved a narrative video designed for Latinas delivered via the internet. The 17-minute video is novella style, with a culturally tailored storyline and setting that covers cervical cancer risk factors and statistics, importance of screening, and addresses testing barriers. The measures were knowledge about cervical cancer and screening, perceived susceptibility, perceived seriousness, perceived benefits, perceived barriers, subjective norms, and self-efficacy. Analysis was performed using change scores for knowledge and psychosocial variables and descriptive statistics for satisfaction and acceptability of the video. RESULTS: Data from 227 surveys were analyzed; respondent mean age: 37.6 years; 98.8% female, 88.8% Hispanic; 42.0% had an annual income of $20,000 or less; and 85.2% had at least a high school education. Knowledge and all psychosocial variables improved significantly. More than 90% of the participants rated all of the satisfaction items as good or excellent. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: A culturally appropriate narrative video about cervical cancer and screening disseminated online effectively improved knowledge and psychosocial variables among Latinas. Our findings indicate that health promotion interventions online could be effective for improving desired health behavior through a new means of educational dissemination by way of websites and social media outlets.

Comparative effectiveness of five fecal immunochemical tests using colonoscopy as the gold standard: study protocol.

BACKGROUND: There are nearly 50,000 colorectal cancer (CRC) deaths in the United States each year. CRC is curable if detected in its early stages. Fecal immunochemical tests (FITs) can detect precursor lesions and many can be analyzed at the point-of-care (POC) in physician offices. However, there are few data to guide test selection. Broader use of FITs could make CRC screening more accessible, especially in resource-poor settings. METHODS: A total of 3600 racially and ethnically diverse individuals aged 50 to 85 years having either a screening or surveillance colonoscopy will be recruited. Each participant will complete five FITs on a single stool sample. Test characteristics for each FIT for advanced colorectal neoplasia (ACN) will be calculated using colonoscopy as the gold standard. RESULTS: We have complete data from a total of 2990 individuals. Thirty percent are Latino and 5.3% are black/African American. We will present full results once the study is completed. CONCLUSIONS: Our focus in this study is how well FITs detect ACN, using colonoscopy as the gold standard. Four of the five FITs being used are POC tests. Although FITs have been shown to have acceptable performance, there is little data to guide which ones have the best test characteristics and colonoscopy is the main CRC screening test used in the United States. Use of FITs will allow broader segments of the population to access CRC screening because these tests require no preparation, are inexpensive, and can be collected in the privacy of one's home. Increasing CRC screening uptake will reduce the burden of advanced adenomas and colorectal cancer.

Breast cancer screening outcomes among Mexican-origin Hispanic women participating in a breast cancer screening program.

Breast cancer is the commonest occurring cancer and the leading cause of cancer death among Hispanic women in the USA. Although their overall breast cancer incidence and mortality is lower, incidence rates are rising faster and mortality declines are lower than other groups. It is expected that the breast cancer burden will rise as this population ages and becomes more acculturated. It is therefore important to better characterize their screening outcomes. This is an observational study of socioeconomically disadvantaged Hispanic women participating in a community-based breast cancer screening program that offered no-cost testing and navigation services in two US-Mexico border counties. Outcomes include results of screening mammograms, diagnostic tests and breast findings. Of 1,966 eligible women, 1,675 (85%) completed a screening mammogram and were included in this analysis. Mean age was 56 years (SD: 6.8 years, range 50 to 75.6 years); 99% were Hispanic and 83.6% had less than high school education. 19.3% of the initial mammogram results were abnormal (BIRADS 0, 3, 4, or 5); a diagnostic mammogram was indicated in 12.2% (n = 205), a diagnostic ultrasound in 26.4% (n = 443), and biopsies in 3.0% (n = 51) of the total. Eleven women (0.66%) had breast cancer diagnosed. Mexican-origin Hispanic women had higher recall rates, but similar biopsy and cancer rates to general screening populations despite their overall lower incidence and mortality in the USA. This suggests that the expected rise in future breast cancer burden among US Hispanics due to aging and acculturation could occur sooner than expected.

Outcomes of a Multicomponent Culturally Tailored Cervical Cancer Screening Intervention Among Underserved Hispanic Women (De Casa en Casa).

Hispanic women have almost double the cervical cancer incidence and are twice as likely to die from cervical cancer compared with non-Hispanic White women. Cervical cancer is preventable with screening, and based on available data, multiple component screening interventions have been proposed as a strategy to maximize screening, but such studies are lacking. We sought to test the effectiveness of a multicomponent screening intervention for primary prevention and early detection of cervical cancer among underserved Hispanic women. We conducted a prospective community-based cervical cancer screening intervention utilizing a quasi-experimental design. The intervention was theory based, delivered by bilingual community health workers, combined education and reduction of noneconomic barriers, and addressed economic barriers. Components included outreach, education, provision of no-cost Papanicolaou and human papillomavirus screening, on-site diagnostic and treatment colposcopy, and patient navigation with tracking to facilitate screening, diagnosis, and treatment. The main outcome was self-reported screening. We recruited 300 intervention group and 299 control group participants. Mean age of the sample was 44.7 years. The majority were Hispanic (98%), born in Mexico (79%), and had a Spanish-language preference (86%). In intention-to-treat analyses, the intervention group had a relative risk of screening of 14.58 (95% confidence interval = 8.57-24.80, p < .001) compared with the control group. A multilevel, multiple component culturally tailored bilingual cervical cancer screening intervention combining education, navigation, and no-cost screening can significantly increase cervical cancer screening uptake in a high-risk, underscreened population and has the potential to affect cervical cancer health disparities.

What are the contextual risk factors for low colorectal cancer screening uptake in El Paso County, Texas? Spatial cross-sectional analysis.

OBJECTIVE: This study examines the geographical and socioeconomic factors associated with uptake of colorectal cancer (CRC) screening (colonoscopies or faecal immunochemical test (FIT) testing). DESIGN: Secondary data analysis. SETTING: The Against Colorectal Cancer in our Community (ACCION) programme was implemented in El Paso County, Texas, to increase screening rates among the uninsured and underinsured. PARTICIPANTS: We successfully geocoded 5777 who were offered a free colonoscopy or FIT testing kit. PRIMARY OUTCOME MEASURE: Census-tract CRC screening uptake average. RESULTS: Medicare recipient mortality (ß=0.409, p-value=0.049) and % 65 years or older (ß=-0.577, p value=0.000) were significant census tract contextual factors that were associated with the prevalence of CRC screening uptake in the geographically weighted Poisson regression. Neither Latino ethnicity nor immigrant concentration were significant predictors of CRC screening uptake in the ACCION programme. Hot spot analysis demonstrated that there was a significant low-value cluster in South Central El Paso. There was a similar hot spot for % 65 years or older in this same area, suggesting that uptake was lowest in an area that had the highest concentration of older adults. CONCLUSION: The results from this study revealed not only feasibility of hot spot analysis but also its utility in geographically tracking successful CRC screening uptake in cancer prevention and intervention programmes.

The Prevalence of Genital Human Papillomavirus Subtypes in a Cohort of Hispanic Women Presenting for Cervical Cancer Screening Along the US-Mexico Border.

Introduction : Hispanic women residing along the US-Mexico border have the highest cervical cancer incidence rates in the US. Genital human papillomavirus (HPV) is the major causative agent, but more information is needed about the prevalence and distribution of genital HPV subtypes in this high-risk population. Methods : A population-based cross-sectional study of uninsured Hispanic women along the US-Mexico border was conducted and participants had their cervical specimens undergo DNA extraction followed by HPV genotype testing using the Linear Assay from Roche® Diagnostics, to identify 37 genital HPV subtypes. Results : Among the 585 women aged 21-65 years, 584 self-identfied as Hispanic. Any HPV subtype prevalence was 53.2% (95% CI: 49.0%-57.3%) and of these 52% (i.e. 27.5% of the total) had single infections and 48% (i.e. 25.6% of the total) had multiple infections. High-risk HPV prevalence was 15.6% (95% CI: 24-31.3%). The mean number of subtypes among those testing positive was 2.1 (SD 1.6). The prevalence of any HPV and high-risk HPV showed a U shaped pattern with age; and prevalence of 16/18 and non-16/18 high-risk subtypes (e.g. 31, 33, 35, 39, 45, 51, 52, 58); also varied with age. Forty-one percent of high-risk HPV occurrences were of a subtype not covered by the current nonavalent HPV vaccine. Discussion : Our findings suggest a different high-risk HPV subtype pattern and age distribution among Hispanic women in the USA, which could have implications for future cervical cancer prevention strategies.

Breast Cancer Fear Among Mexican American Women in the United States.

INTRODUCTION: Fear has been described as potentially important in affecting breast cancer screening completion. Limited information is available on the prevalence and determinants of fear among Mexican American women. This study describes perceived breast cancer fear and its association with personal characteristics and screening behavior among Mexican American women. METHODS: This is a secondary analysis of data collected during the implementation of the Breast Cancer Education, Screening and NavigaTion program among eligible uninsured women in two Texas border counties. Participants completed a 26-item survey to assess eligibility, risk status, prior screening, and breast cancer fear. Descriptive statistics and multivariable analyses were used to determine associations between the fear score, personal characteristics, and mammography screening. RESULTS: In all, 1916 of 2012 eligible women completed the study. The mean age was 57.3 years, 99.2% were Hispanic, and 88% were born in Mexico; 15% had a family history of breast cancer and 14% had never had a mammogram. The mean breast cancer fear score was 25.5 (standard deviation: 10.52; range: 8-40); 54.0 % (95% confidence interval: 52.1%-56.7%) had a high fear level. In multivariable analyses, better health status (P < .001), older age (P = .039), birth in the United States (P = .020), and having a regular doctor (P = .056) were associated with lower fear scores. There was no association between breast cancer fear and mammography screening. CONCLUSION: Breast cancer fear is high and varies by personal characteristics and health status among uninsured Mexican American border-residing women due for screening, but is not associated with screening behavior. Further research is needed to clarify the effect of interventions designed to help reduce breast cancer fear among these women, including educational interventions to reduce breast cancer fear.

Impact of a Culturally Tailored Diabetes Education and Empowerment Program in a Mexican American Population Along the US/Mexico Border: A Pragmatic Study.

BACKGROUND: The study purpose was to deliver a diabetes education program under real world conditions and evaluate its effect on diabetes-related clinical, self-management and psychosocial outcomes among Mexican Americans residing along the US/Mexico border. METHODS: A pragmatic study was conducted among adult patients with diabetes in three primary care clinics located along the US/Mexico border. A bilingual culturally tailored diabetes education program incorporating hands-on participatory techniques was delivered in 4 - 8 weekly group sessions. Clinical, self-management and psychosocial outcomes were evaluated pre- and post-intervention with surveys and medical record review. RESULTS: A total of 209 participants were enrolled; mean age was 58.9 years (range 23 - 94, standard deviation: 11.2); 68.4% were female; 91.1% were Hispanic. Significant improvements were observed in glycated hemoglobin (-1.1%, P < 0.001, n = 79), total cholesterol (-17.2 mg/dL, P = 0.041, n = 63), glucose self-monitoring (+1.3 times a week, P = 0.021, n = 115), exercise less than once a week (-18.2%, P < 0.001, n = 129), nutritional behavior (+2.23, P < 0.001, n = 115), knowledge (+1. 83, P < 0.001, n = 141) and diabetes-related emotional distress (-7.32, P = 0.002, n = 111). Benefits were observed with attendance rates as low as 50%. CONCLUSION: A clinic-based culturally competent diabetes education/self-management program resulted in significant improvements in outcomes among Hispanic participants. Experimentally tested culturally appropriate interventions adapted for real world situations can benefit Mexican American diabetic patients even when attendance is imperfect.

Using Electronic Medical Record Data to Better Understand Obesity in Hispanic Neighborhoods in El Paso, Texas.

The prevalence of obesity has been persistent amongst Hispanics over the last 20 years. Socioeconomic inequities have led to delayed diagnosis and treatment of chronic medical conditions related to obesity. Factors contributing include lack of insurance and insufficient health education. It is well-documented that obesity amongst Hispanics is higher in comparison to non-Hispanics, but it is not well-understood how the socioeconomic context along with Hispanic ethnic concentration impact the prevalence of obesity within a community. Specifically studying obesity within Hispanic dominant regions of the United States, along the Texas-Mexico border will aid in understanding this relationship. El Paso, Texas is predominantly Mexican-origin Hispanic, making up 83% of the county's total population. Through the use of electronic medical records, BMI averages along with obesity prevalence were analyzed for 161 census tracts in the El Paso County. Geographic weighted regression and Hot Spot technology were used to analyze the data. This study did identify a positive association between Hispanic ethnic concentration and obesity prevalence within the El Paso County. Median income did have a direct effect on obesity prevalence while evidence demonstrates that higher education is protective for health.

The Association of Background Parenchymal Enhancement at Breast MRI with Breast Cancer: A Systematic Review and Meta-Analysis.

BackgroundThe higher level of background parenchymal enhancement (BPE) at breast MRI has the potential for early detection and prediction of the risk of breast cancer. However, conflicting findings have been reported about the association between the level of BPE at breast MRI and the presence of breast cancer.PurposeTo evaluate the association between qualitative and quantitative BPE at dynamic contrast material-enhanced MRI and breast cancer among populations with average risk and high risk separately.Materials and MethodsA retrospective meta-analysis of observational studies comparing either qualitative or quantitative assessments of BPE in women with and women without breast cancer was performed for studies published through July 2018. Pooled odds ratios (ORs) or standardized mean differences and 95% confidence intervals (CIs) were estimated by using DerSimonian-Laird random-effects models. The heterogeneity across the studies was measured by using the statistic I 2. Sensitivity analyses were conducted to test this association according to different study characteristics. P values less than or equal to 5% were considered to indicate statistically significant results.ResultsEighteen studies comprising 1910 women with breast cancer and 2541 control participants were included in the analysis. Among women with high risk, at least moderate BPE (OR, 1.6; 95% CI: 1.0, 2.6; P = .04) or at least mild BPE (OR, 2.1; 95% CI: 1.5, 3.0; P < .001) was associated with higher odds of breast cancer. Furthermore, women with breast cancer showed a higher average BPE percentage compared with control participants with high risk (standardized mean difference, 0.5; 95% CI: 0.2, 0.9; P = .001). No association was observed between at least mild BPE level (P = .15) or at least moderate BPE level (P = .38) and the presence of breast cancer among the population with average risk.ConclusionA higher level of background parenchymal enhancement measured at breast MRI is associated with the presence of breast cancer in women with high risk, but not in women with average risk.© RSNA, 2019Online supplemental material is available for this article.See also the editorial by Mann and Pinker in this issue.

Hereditary Breast Cancer Risk Analysis in Uninsured Mexican-Origin Women Living in the U.S.-Mexico Border Region.

PURPOSE: This article describes the risk of hereditary breast cancer (HBC) in low-income Hispanic women living on the U.S.-Mexico border using the Pedigree Assessment Tool (PAT). METHOD: The PAT was administered as part of the El Paso and Hudspeth County Breast Cancer Education, Screening and NavigaTion program (BEST). Baseline data (n = 1,966) from this program was used to analyze risk factors for HBC. Analysis was conducted to determine significant covariates associated with the presence of any PAT risk factors. RESULTS: The PAT identified 17% (95% CI [15%, 19%]) of the women in the study as having some risk of HBC. Having had a mammogram within 3 years was significantly associated with having any PAT risk factors (odds ratio [OR] = 1.79, p = .006). Women who immigrated to the United States during childbearing age (OR = 0.610, p = .009) or during peri/menopause (OR = 0.637, p = .024) were significantly less likely to have any PAT risk factors. DISCUSSION: The PAT instrument detected a substantial pool of women who may be at risk for HBC. A significant proportion of these women were not up to date mammogram. CONCLUSIONS: The PAT is an effective tool to identify women at risk for HBC and encourage regular screening.
