  • Latinx individuals in the US have a higher prevalence of Type 2 diabetes by 13%, which is more than the national average. Poorly managed diabetes can lead to serious complications such as diabetic retinopathy, amputations, or cardiovascular disease, making it critical to understand the factors that can help support effective diabetes management and medication adherence. Although prior research studies have linked social networks to health behaviors and adherence, limited research has focused on older Latinx adults living with diabetes. The purpose of this study was to examine how perceived social support influences diabetes management and medication adherence among Latinx Adults aged 65 and older. Using a qualitative design, data were collected through a short survey followed by a focus group with 5 older Latinx participants and one additional patient through an individual interview, 4women, 2 men, ranging in ages 65 to 86 years of age, discussing their day-to-day experiences managing diabetes, taking medication, and the support they receive. Findings suggest that social support plays a significant and complex role in diabetes management. Support from family that helps in practical ways, such as reminders, assistance picking up medication, and transportation, often improves medication adherence. At the same time, however, support was not always experienced or described positively, with participants reporting they would sometimes feel judged, controlled, and even stigmatized by their family members and other members of the community, especially around food restrictions, while others described limited involvement from family. Overall, these findings help show that perceived social support affects diabetes medication adherence not only with direct assistance but also with emotional and healthcare access. Our results highlight the need for better cultural understanding, family-informed and accessible interventions that can help strengthen supportive relationships and address barriers that impact this population.tion text goes here

  • Latinx people with ADHD face issues with delayed diagnosis and treatment, having approximately 8% of youth diagnosed with ADHD compared to 11% of their non-Hispanic counterparts. ADHD in Latinx communities is often surrounded by stigma and misinformation. Latinx students specifically often face delays in accessing care, which has been shown to correlate to poorer academic performance, poorer mental health, and a worse application of long-term support systems. This lack of access to care and decreased likelihood of receiving a diagnosis highlights the importance of studying the common issues, barriers, and facilitators faced when navigating this environment. This project, currently in progress, aims to find these factors by surveying and interviewing Latinx UCI students with ADHD. During a 70-minute interview, we collect demographic information, age of diagnosis and treatment, and the self-reported experiences of Latinx UCI students who present with a formal ADHD diagnosis and are aged 18 or older. Participants receive a $20 gift card for completing the interview. Interviews are recorded, transcribed, and deidentified for patient confidentiality, then analyzed by the research team using thematic analysis. From our first two completed interviews have found themes between them that show a delay in ADHD diagnosis and access to treatment from intersecting factors. These included racial disparities in recognition of symptoms, immigration-related family resistance to treatment, and insurance and medication access issues. Our overall dilemma is a reflection of how our healthcare and awareness system is failing these communities, and by implementing more culturally-tailored resources over surface-level translations, we would be able to address much of the stigma at its origin. Building on these preliminary findings, we will improve on this by building upon our outreach resources and scope.


Feasibility of an Audio-Vignette Study on Spanish Communication Style in Healthcare


  • Effective communication between healthcare providers and Spanish-speaking patients is essential for quality care, yet differences in communication style may influence patient understanding and perceptions. While prior research has focused on language concordance, less is known about how variations in Spanish communication style such as formal versus conversational approaches affect patient experience. This study aimed to evaluate the feasibility of using an audio vignette–based survey to assess these differences. In this pilot study, adult participants (N = 6) completed an online survey administered via REDCap. Participants listened to a short (~90-second) Spanish-language audio vignette in either a formal/technical or conversational/culturally aligned style describing hypertension. Following the vignette, participants completed Likert-scale measures assessing trust, language quality, and perceived comprehension, as well as knowledge-based questions to assess objective comprehension. Survey completion time and response patterns were examined to evaluate feasibility. All participants completed the survey with no missing responses, indicating high engagement and feasibility of the study design. Descriptive results demonstrated variability in both perceived and objective comprehension across participants. Survey completion time varied by age group, with participants aged 18–24 completing the survey in approximately 6 minutes on average, compared to approximately 17 minutes for participants aged 25–34 and 45–64. These findings suggest that audio vignette based surveys are a feasible approach for studying Spanish-language healthcare communication and can generate meaningful, variable data for larger-scale studies, though differences in completion time across age groups may have implications for usability. Future research with a larger sample size is needed to further evaluate the impact of communication style on patient outcomes.

  • Breast cancer is the most common cancer among women worldwide. In the United States, it affects one-in-eight White women and one-in-nine Hispanic/Latina women with fewer breast cancer diagnoses than their white counterparts, but are 20% more likely to be diagnosed with an advanced or late-stage of breast cancer, suggesting poorer access to screening and early detection. Promotoras, or community health workers that provide health resources and culturally-tailored health education to Latine communities via interactive group discussions or private one-on-one conversations, have been shown to increase knowledge and access for preventive health resources, but little is known specifically about the experience of women who receive education on breast cancer from promotoras. This qualitative study analyzed the impact of promotoras on Latinas learning and engagement with breast cancer topics. Promotoras are community health workers that provide health resources and culturally-tailored health education to Latine communities via interactive group discussions or private one-on-one conversations to address concerns related to health exams. There is a lack of research on the role that local community members such as promotoras have in supporting patient’s understanding of health screenings. To evaluate the impact of integrating cultural relevance in health education via promotoras, eight Spanish-speaking Latinas completed in-person interviews before and after receiving information on breast cancer and mammograms. Using a thematic analysis approach, the following three themes were identified: (1) addressed breast cancer and health screenings knowledge gaps, (2) changes in attitudes with sensitive topics, (3) and sustained motivation to continue learning about breast cancer. Latina participants highlighted that promotoras helped them understand mammograms, recognize abnormalities in their chest area, and motivated them to become more proactive in their own health even if it is not related to breast cancer. Findings suggest that culturally-tailored health education provided by promotoras may improve Latinas knowledge and empower Latinas to openly discuss topics relating to breast cancer and mammograms. These results emphasize the importance of community-based education intertwined with cultural components as an avenue for public awareness of breast cancer and mammograms.

Language Access as a Determinant of Cardiometabolic Outcomes: Associations Between Interpreter Use, Blood Pressure, and Medication Beliefs Among Latinx Adults



  • Managing cardiometabolic conditions such as diabetes and hypertension can be especially challenging for patients who face language barriers, as understanding treatment and feeling heard are essential to effective care. This study builds on the Mi Propio Camino (MPC) study, which focuses on how medication beliefs influence adherence among Latinx patients, many of whom experience concerns about medications that are not always addressed in clinical settings. This study examined whether access to medical interpreters is associated with blood pressure control, measured by 1-month systolic blood pressure, and whether medication beliefs help explain this relationship among Latinx adults receiving care at federally qualified health centers. Interpreter access was associated with more positive medication beliefs, suggesting that improved communication may help patients feel more informed and supported. However, interpreter access was not associated with 1-month systolic blood pressure, and medication beliefs were not related to blood pressure outcomes. These findings suggest that while communication is an important part of care, it may not be enough on its own to improve clinical outcomes. Supporting patients in managing chronic conditions likely requires addressing not only how care is communicated, but also the broader challenges they face in their daily lives.

  • Delays in communicating test results can lead to missed treatment opportunities and reduced trust between patients and providers, particularly among underserved communities. Telehealth has emerged as a critical tool for improving access to care. This study examines how digital accessibility and telehealth-related factors influence perceptions of patient-centered care among Hispanic/Latino patients receiving care at UC Irvine’s FQHC. Guided by principles of patient-centered care and the Theory of Planned Behavior, this research explores the role of digital access, telehealth usability, and cultural responsiveness in shaping patient experiences. Data were collected from Mi Propio Camino, an NIH-funded study conducted by the HELIOS Lab focused on hypertension management among Spanish-speaking Hispanic/Latino patients. Participants were recruited from UC Irvine’s FQHC in Santa Ana/Anaheim and completed questionnaires assessing understanding of their hypertension diagnosis, treatment adherence, and perceptions of telemedicine. It will examine associations between digital accessibility, telehealth attitudes, subjective norms, perceived behavioral control, and patient-centered care outcomes. We hypothesize that patients who perceive telehealth services as accessible, personalized, and culturally responsive will report higher levels of patient-centered care compared to those experiencing digital barriers. Additionally, positive attitudes toward telehealth, supportive subjective norms, and greater perceived behavioral control are expected to be associated with enhanced perceptions of patient-centered care in virtual settings. Findings from this study aim to inform culturally responsive and equity-driven telehealth interventions and highlight the importance of addressing digital and language barriers to improve patient-centered care among Hispanic/Latino populations in safety-net healthcare settings.

  • Today's revolutionary drug Glucagon-like peptide-1 receptor agonists (GLP-1) is an extremely effective treatment for type 2 diabetes. However, diabetic patients have limited access to GLP-1 treatment, raising concerns about disparities in diabetes care. This study investigates clinical, behavioral, insurance, and patient-level factors that are associated with GLP-1 prescription among adults with type 2 diabetes. The study analyses data from electronic health records from HELIOS Lab’s Mi Propio Camino (MPC) study. The outcomes being observed are GLP-1 order status and duration of use. Independent variables include age, gender, body mass index (BMI), HbA1c, insurance type, medication beliefs, and patient-centered care. SPSS will be used to determine descriptive statistics and any associations between the patient factors and GLP-1. In a multivariable logistic regression analysis, higher BMI and elevated A1c levels were significant predictors of GLP-1 prescription. Each unit increase in BMI was associated with greater odds of receiving a GLP-1 (OR = 1.09, p < .001). Patients with A1c levels of 7–9 (OR = 4.1, p = .004) and ≥9 (OR = 12.8, p < .001) had substantially higher odds of prescription. Patient-centered care was not a statistically significant predictor (p = .09), although a positive trend was observed. Overall, these findings indicate that clinical indicators, particularly glycemic control and BMI, are the primary drivers of GLP-1 prescribing. This study's purpose is to identify key determinants of GLP-1 access and continuity of use, providing insight into structural and patient-level barriers to current diabetes treatment. By informing these insights, we aim to improve equity in diabetes care.

  • GLP-1 agonists, such as Ozempic, Wegovy, Zepbound, Victoza have revolutionized the management of type 2 diabetes—and more recently, obesity. These medications not only improve glycemic control, but they also reduce cardiovascular risk and promote significant weight loss. They’re becoming a cornerstone of modern metabolic care. With the recent changes to GLP-1 coverage announced by MediCal concerning cuts to coverage for those using GLP-1s such as Wegovy and Zepbound for weight loss purpose, it is important to understand the views of physicians and patients on such decisions as well as the impact GLP-1s have had on their lives. This qualitative study aims to understand the experiences of patients with GLP-1 agonists. Interviews will be conducted with patients who have Type 2 diabetes to learn what they were hesitant about before taking GLP-1s, their experiences taking them and how they’ve affected their lives. Patients will also be asked if their coverage plan has changed and how it has affected them.

  • Latino/Hispanic adults experience disproportionately high rates of Type 2 diabetes, yet many diabetes self-management strategies fail to account for the cultural and familial factors that influence health behaviors within these communities. This study applies the Theory of Planned Behavior to examine how family dynamics shape diabetes self-management behaviors among Latino/Hispanic adults. Within many Latino/Hispanic households, collectivism, interdependence, and shared family responsibility strongly influence attitudes, perceived social norms, and perceived behavioral control related to health decision-making.
    The purpose of this project was to explore how family influences affect diabetes self-care behaviors, including dietary habits, physical activity, medication adherence, and glucose monitoring. A qualitative, theory-driven approach was used to analyze how family attitudes, expectations, and support systems may either encourage or hinder effective disease management. Findings suggest that family members frequently act as both motivators and barriers by reinforcing cultural practices surrounding food, caregiving, and health behaviors.
    This research highlights the importance of moving beyond individual-centered health models and incorporating the broader social and cultural context into diabetes care. By integrating family-centered perspectives into the Theory of Planned Behavior framework, this study provides a more comprehensive understanding of diabetes self-management within Latino/Hispanic populations. The findings support the development of culturally tailored, family-based interventions that leverage family support systems to improve diabetes outcomes, reduce health disparities, and promote sustainable long-term disease management.

  • Hispanic individuals experience higher rates of type 2 diabetes, a chronic metabolic condition where the body becomes resistant to insulin, making it difficult to maintain normal blood glucose levels. Previous studies show that DSME (Diabetes Self-Management Education) programs help patients manage diabetes effectively, but traditional models often fail to meet the cultural, linguistic, and access needs of marginalized Hispanic communities.

    To explore a more culturally competent framework, we evaluated a Group Medical Visit (GMV) model at the UCI Family Health Center in Santa Ana, integrating medical care with group-based diabetes education, peer support, culturally tailored teaching, and shared discussion with a healthcare provider. Pre‑ and post‑intervention surveys assessed lifestyle habits, food behaviors, diabetes management, and attitudes. The Arizona Lifestyle Index measured weekly (0–7 days) engagement in key health behaviors. Data was analyzed using SPSS and REDCap to generate a quantitative dataset.

    The Arizona Lifestyle Index increased from 3.5 to 4.4 days/week after GMVs (+0.9, p = .002). Statistically significant improvements (p < .05) were observed in behaviors emphasized during the GMV curriculum, including vegetable intake, relaxation/stress‑management activities, and sleeping 7–9 hours. This suggests that interventions in GMVs improve outcomes by promoting healthier lifestyle behaviors.

As Type 2 diabetes cases rise, insulin self-titration becomes increasingly important for managing blood glucose levels. While effective, many patients are reluctant to adopt this titration method due to various barriers. Understanding patients’ perspectives are essential for improving self-management strategies for diabetic patients. This study aims to explore the perspectives of UCI Family Center in Santa Ana patients with uncontrolled diabetes regarding insulin self-titration, identifying key barriers to its implementation. Focus groups were conducted effectively to assess patient experiences in navigating diabetes management and their attitudes towards this titration method. 14 patients participated providing valuable insights into clinical and personal challenges. An inductive thematic analysis was conducted from the focus groups identifying recurring themes in responses. The study’s findings suggest that the patients encounter several challenges in adopting insulin self-titration, including mistrust and uncertainty, fear and apprehension, and knowledge gaps. Additionally, patients expressed preferences for clear, physician-led instructions, and language accessibility to improve comprehension. These results emphasize the complexity of self-titration adoption and highlight the need for educational support. Addressing these barriers may improve patient confidence, promote self-management, and lead to better glycemic control. Future research should focus on developing interventions that enhance provider support, and develop strategies to empower patients to confidently self-titrate insulin.

Patient-centered care (PCC) has emerged as a critical approach in addressing health disparities by prioritizing the individual needs, preferences, and cultural backgrounds of patients. This is especially vital in communities where language and systemic barriers often hinder access to quality care. This study examines the impact of Patient-Centered Care (PCC) on medication adherence among Spanish-speaking hypertensive patients in Santa Ana, a population that faces significant healthcare disparities due to language barriers and limited access to culturally competent care. By exploring the connection between PCC and adherence, this study aims to identify strategies for improving treatment outcomes in this underserved community. Survey data from 390 patients at UCI’s clinic assessed PCC through an 11-question survey on patient-doctor relationships and visit experiences. Findings suggest that patients who reported positive interactions with their doctors had higher PCC ratings and better medication adherence, while those who experienced negative visits were less likely to adhere to their prescribed treatment. These results highlight the importance of fostering strong patient-doctor relationships to improve medication adherence and overall health outcomes in Latinx populations.

Hispanic Americans experience a disproportionate incidence of food insecurity, contributing to higher rates of chronic conditions like hypertension. The Mi Propio Camino (MPC) study evaluated a culturally tailored group medical visit model to improve blood pressure (BP) management and medication adherence in the Latinx community. A total of 650 hypertensive Hispanic patients from UCI FQHCs were retrospectively divided into food secure (FS, n=313) and food insecure (FI, n=355) groups. Participants completed a four-session hypertension management course, with pre- and post-intervention assessments of BP, lifestyle habits, and self-reported medication adherence. At baseline, FI patients had similar BP readings to FS patients but showed lower adherence to medication (t=-1.548, p=0.061) and healthy behaviors (t=4.123, p<0.001). One month after the intervention, BP differences remained nonsignificant (t=0.596, p=0.277), while the FI group showed improved medication adherence (non adherence decreased from 57.26% to 48.23%) and lifestyle behaviors (mean increased from 3.64 to 4.44; t=-0.778, p=0.219). Following MPC, a subset of patients with FI were invited to a focus group to share patient perceptions of experiences of managing FI with high blood pressure. Focus groups with FI patients (n=6) highlighted a strong desire to eat healthy, but persistent social and economic barriers. These findings suggest community-based, culturally sensitive education can support improved hypertension outcomes and address medication hesitancy. Ongoing follow-up and thematic analysis will further explore the impact of food insecurity on patient health behaviors.

Medication non-adherence is a significant contributor to poor chronic disease outcomes, particularly within the Latinx community. Failing to follow prescribed medication can lead to worsening health conditions, increased complications, and higher rates of hospitalization. Previous research has shown that the Safran Reasons for Non-adherence Scale (SRNS) is a valid predictor of health outcomes for Latinx adults with hypertension.This study compares the validity of two self-reported vs. objective measures of non-adherence to predict successful hypertension management. Spanish-speaking adult patients with hypertension were enrolled and asked to use MEMS caps, which recorded each time the pill bottle was opened over a 30 day period. After 30 days, participants returned for a follow up visit where MEMS caps were collected, blood pressure (BP) was measured and both MMAS and SRNS were administered. Participants were categorized as “Self-reported adherent” or “Self-reported non-adherent” based on survey responses. Objective non-adherence was defined as taking less than 80% of prescribed doses, as determined from MEMS data, and was compared between the self-reported adherent and non-adherent groups using independent sample t-test. BP levels were compared between adherent and non-adherent patients for both measures using independent samples t-tests. The MEMS cap detected fewer non-adherent patients (35%) compared to MMAS (44%) and SRNS (64%), highlighting disagreement across methods. However, only MEMS based adherence was strongly associated with blood pressure outcomes, with non-adherent patients showing significantly higher systolic and diastolic BP (p<0.001). These findings suggest that while self-report tools identify more perceived barriers, objective monitoring provides a more reliable predictor of future blood pressure control.

Medication nonadherence remains a pervasive issue in clinical care, leading to adverse health outcomes and increased healthcare costs. While numerous factors contribute to nonadherence, language barriers are often overlooked. As part of the Mi Propio Camino (MPC) study—a broader investigation into barriers to chronic disease management in diverse populations—we hypothesize that patients who need an interpreter but lack consistent access to one are more likely to report low medication adherence. This analysis explores how interpreter availability affects self-reported medication adherence among patients with varying levels of language access. We analyzed baseline data from 666 patients who completed the Morisky Medication Adherence Scale (MMAS) as part of the MPC study. Patients were grouped based on interpreter access: (1) Interpreter Not Needed (n = 232), (2) Interpreter Always Available (n = 249), and (3) Interpreter Not Always Available (n = 185). Nonadherence was coded as a binary outcome (1 = low adherence, 0 = moderate/high adherence). Adherence rates were compared across groups using one-way ANOVA. Significant differences in adherence were found between the three groups (p < 0.001). The proportion of patients reporting low adherence increased with decreased language access: Interpreter Not Needed: 50.0%, Interpreter Always Available: 59.0%, and Interpreter Not Always Available: 74.0%. Language access is a critical determinant of medication adherence. Patients who required but did not consistently receive interpreter support were more likely to report nonadherence. These findings underscore the need for healthcare systems to invest in consistent interpreter services and language-concordant care to promote equity and improve patient outcomes.

Understanding the Impact of Health Literacy on Medication Adherence within the Hispanic/Latinx Community

Stacy Segura

Health Literacy among the Hispanic community is a crucial issue that is often overlooked due to multifaceted factors such as language barriers, economic issues, and food insecurity. Health literacy—a patient’s ability to understand the degree of their overall health and comprehend medical treatment plans— is a major contributing factor impacting medication adherence. This is significant because the depth of understanding one’s diagnosis and treatment contributes in the expansion of better health management and better health outcomes. Medication Adherence continues to be a challenge due to persistent communication gaps and limited knowledge exchange between patients and providers. The purpose of this research is to access how 391 Spanish-speaking Hispanic/Latinx patients at the UC Irvine’s Federally Qualified Health Center (FQHC) understand their diagnoses and how this understanding affects their adherence to prescribed medications. This was evaluated through three major health literacy measures; did the provider check the patient’s understanding, was the patient satisfied with interpersonal care, and was the patient involved in decisions regarding their medication. Additionally, the findings concluded that 67% of patients whose provider checked their understanding had low adherence (p=0.363), 71% of patients who did not have a provider with strong interpersonal care had low adherence (p=0.02), 72.2% of patients whose provider did not involve them in decision-making had low adherence (p=0.03). The hypothesized results suggest that patients with higher health literacy and stronger communication with the provider demonstrate higher levels of medication adherence in additional to better lifestyle changes. These results underscore the importance of addressing health literacy and provider-patient barriers. Utilizing this data can inform strategies to improve health outcomes by strengthening patient engagement, education, and culturally competent care within the Hispanic/Latinx communities.

Imagine choosing between buying groceries for your family and refilling a prescription for your high blood pressure. For many low-income Hispanic patients, this is not just hypothetical, it is a daily reality. My study examines how life tradeoffs such as financial constraints, conflicting obligations, and beliefs about medication overuse influence medication adherence among Hispanic patients receiving care at UCI’s Federally Qualified Health Centers (FQHCs). While prior studies focused on general barriers to medication adherence, like language, cost, or access, few have closely examined the specific tradeoffs patients are actively making. Patients at UCI FQHCs were surveyed on financial tradeoffs and medication adherence. Patients who answered “often” or “sometimes” had to cut back on other expenses and were grouped as Yes Tradeoffs. Patients who answered “never” were grouped as No Tradeoffs. We compared adherence scores and analyzed beliefs about medications using four subscales: General Overuse, General Harms, Specific Necessity, and Specific Concerns. Among the 668 patients surveyed, those who reported making financial tradeoffs, such as cutting back on basic needs to afford medications, had significantly lower medication adherence rates than those who did not. 74% of patients in the Yes Tradeoffs group (N=122) reported non-adherence, while 57% of those in the No Tradeoffs group (N=546)  reported adherence. Patients who experienced tradeoffs also held more negative beliefs about medications. These findings highlight the need for healthcare providers to engage in more empathetic and personalized conversations with patients to address economic realities and medication concerns to improve health outcomes.

Experiencing language barriers in accessing healthcare is a prevalent issue within the Hispanic community, often resulting in limited access to healthcare services and disparities in treatment and outcomes. With Spanish being the second most spoken language in the US and a high prevalence of hypertension among Hispanic adults in the US (64.5%), addressing this issue is critical. This study aims to investigate the impact of interpreter availability on the quality of patient-centered care (PCC) and interpersonal processes of care (IPC) for Spanish-speaking hypertensive patients. PCC was assessed through an 11-question survey focusing on patient-doctor relationships, while IPC was evaluated based on consistent interpersonal care, provider communication, and patient involvement in decision-making. Survey data was collected from 390 Spanish-speaking hypertensive patients at UCI’s clinic in Santa Ana and categorized into three groups based on interpreter accessibility (interpreter not needed, interpreter always available when needed, and interpreter not always available when needed). Results indicate that inadequate interpreter access significantly diminishes the quality of care received by patients. Understanding the influence of interpreter availability on patient care is crucial for improving healthcare delivery, particularly for Spanish-speaking hypertensive patients. Ultimately, to enhance the overall quality of care provided to hypertensive Spanish-speaking patients improving health outcomes within this population.

Hispanic Americans face disproportionate challenges with food insecurity, leading to elevated rates of chronic conditions such as hypertension. The Mi Propio Camino (MPC) study uses a group medical visit model to assess the efficacy of culturally tailored blood pressure (BP) management classes in improving medication adherence and hypertension prognosis within the Latinx community. The study recruited 650 hypertensive Hispanic patients from UCI FQHCs, dividing them retrospectively into food secure (FS) (n=313) and food insecure (FI) (n=355) groups. Participants underwent a four-session hypertension management course. Pre- and post-intervention assessments included BP measurements, adherence to healthy lifestyle choices, and self-reported medication adherence. At baseline, FI patients exhibited comparable systolic and diastolic BP values (t=-.292, p=0.385, and t=-.807, p=0.210, respectively) to FS patients but demonstrated lower medication adherence (t=-1.548, p=0.061) and healthy behaviors adherence (t=4.123, p<0.001). One month following classes, BP values showed no significant difference between the FI vs. FS groups (t=0.596, p=.277), while medication nonadherence decreased (from 57.26% nonadherent to 48.23% nonadherent) and healthy behaviors (x = 3.64, s=1.26 to x = 4.44, s=1.11) improved in the FI group (t=-0.778, p=0.219). These findings suggest that community-based classes may positively influence blood pressure management and decrease culturally reinforced medication hesitancy. We hope to monitor patients’ progress over time and conduct a focus group to understand the nuances of food insecurity in patients’ lives.

Many undergraduate students join research labs to gain experience in their desired field of study. Although studies have described the general benefits of undergraduate research, more information is needed to determine how labs affect student confidence in fulfilling their desired careers. This study focuses on the HELIOS Lab at UCI, which aims to create a more equitable healthcare system by training the next generation of healthcare professionals. The goal of this study is to conduct an internal review of the HELIOS Lab, examine how the lab supports students, and determine whether participation in the lab leads to higher student confidence in their career goals. HELIOS students were given an intake, quarterly, and exit survey where they answered questions about themselves, their confidence level, and support from UCI faculty on a scale of 1 to 5, with 1 indicating not confident/supported at all and 5 indicating extremely confident/supported. Of the 38 students, 82% identified as first-generation and 68% as Hispanic/Latinx. Overall, students felt more supported by faculty within the HELIOS Lab compared to outside faculty. Additionally, students had a higher average confidence level in the exit form compared to the intake form (4.18 + 0.84 versus 3.56 + 0.81, respectively). These results provide preliminary information suggesting that the HELIOS lab has features that improve student confidence. More work is needed to determine which research lab practices are useful for students. This information will allow other UCI labs to prioritize useful tools to help their students.

Cardiorenal syndrome (CRS) encompasses a range of pathophysiological conditions affecting the heart and kidneys, where dysfunction in one organ can lead to dysfunction in the other, either acutely or chronically. The prevalence of CRS is on the rise globally, attributed to the increasing incidence of acute and chronic cardiovascular diseases (CVD), resulting in elevated rates of hospitalization, symptom severity, mortality, and healthcare expenditures. Despite the disproportionate impact of CVD on marginalized communities, the influence of disparities on CRS remains understudied within diverse populations. The purpose of this research is to investigate how health disparities impact the overall experience and management of Cardiorenal Syndrome (CRS) within the Latino community. The problem we are trying to solve in this research project is to understand and address the health disparities prevalent in the Latino community, particularly CRS. By examining how these disparities affect the overall experience and management of CRS among Latinos, including their access to healthcare, treatment efficacy, and overall quality of life, we aim to identify areas for intervention and improvement in healthcare delivery and outcomes for this population.

The Hispanic population faces a higher risk of suffering from food insecurity, primarily stemming from financial constraints that hinder consistent access to nutritious meals. Research has shown that when a family’s income decreases, they are most likely to shift to buying cheaper food choices, but few studies investigate the additional impact of emergency savings on the ability of patients to follow dietary recommendations. Our study examined the impact of food insecurity status and emergency savings on adherence to dietary recommendations in Hispanic patients with hypertension (N = 663) from UC Irvine’s Family Qualified Health Centers. Patients completed a questionnaire where they answered questions related to their food insecurity status, emergency savings, and the number of days they ate breakfast/fruits or vegetables. Patients were categorized into 3 groups, those who were food secure with emergency savings, food secure with no emergency savings, and food insecure (regardless of whether or not they had emergency savings). We found that patients who were food secure with emergency savings reported eating breakfast more days (M = 6.4) compared to those who were food secure with no savings (M = 5.8) and those who were food insecure (M = 5.6). Our results suggest that emergency savings are important when considering adherence to dietary recommendations for those who are food insecure and food secure. Therefore, addressing food deserts, increasing funding for food assistance programs, and creating community partnerships are crucial for increasing food security in low-income communities where emergency savings are scarce.

Emergency room (ER) overutilization leads to overcrowding, higher medical bills, and poorer quality of care. Because Black patients have a higher prevalence of utilizing the ER for avoidable cases, this contributes to racial health disparities. To better understand this pattern, this study sought associations between race, healthcare discrimination, and ERuse. Self-reported data was collected from over 45,000 California adults surveyed in the 2021-2022 California Health Interview Survey (CHIS) Public Use File. Then, the data was analyzed with STATA 18 software, using unadjusted and adjusted logistic regression models with sample weighting. Adjusted models were controlled for covariates including age, gender, chronic conditions, history of COVID-19, and having a usual source of care other than the ER. It was found that Black adults had significantly higher odds of being discriminated against compared to non-Hispanic White adults (25% vs. 2%, p<0.0001), as well as slightly higher rates of visiting the ER (23% vs. 16%, p=0.001). When controlling the responses for covariates, it was found that regardless of race, Californians had a 22% greater odds of using the ER if they had experienced healthcare discrimination (p=0.0006). When comparing Black and non-Hispanic White Californians who had not experienced healthcare discrimination, ER use was similar among both populations, although this finding was not statistically significant (18.4% vs. 16.2%, p>0.05). However, when Black and non-Hispanic White Californians who had experienced healthcare discrimination, Black Californians had higher odds of using the ER (34.9% vs. 25.6%, p<0.05). These findings reveal the strong association that healthcare discrimination has with ER use. Additionally, they reveal the higher odds that Black Californians have of experiencing healthcare discrimination than non-Hispanic White Californians. These results may explain, in part, the racial health disparity Black patients face in the context of ER use. However, with this being a cross-sectional study, it is unknown whether or not discrimination occurred in a primary care office or within the ER itself. This may be the basis of future studies.

This research aims to investigate the primary concerns hindering regular Pap smear screenings among women from underserved communities and lower socioeconomic backgrounds to address the issues with physician-centered care and patient-centered teachings. The study seeks to identify the predominant fears preventing patients from undergoing regular pap smear screenings, especially those near the Orange County area as opposed to other studies which survey broader regions or other countries. The questionnaire surveys were given by students in person to patients who had not scheduled a pap smear by the guideline-recommended date. Surveys involved questions regarding patient's experiences, stigmas, and socioeconomic background in relation to their cervical health.

Relevant literature demonstrates that stigma and discrimination in the healthcare industry from language often leads to apprehensive attitudes toward receiving proper treatment for patients’ conditions, limiting the treatment options patients have. Understanding what factors are involved in a patient seeking treatment is crucial to gaining better insight for what rhetoric to use with these patients in the field of integrative medicine (IM). In a pilot study involving 90 patients with mood/stress related disorders from the UCI Family Medical Center in Santa Ana, California, patients’ attitudes toward IM services were assessed. Taking approximately five minutes per questionnaire, a background assessment was used to collect patient demographics such as age, gender, education level, religious orientation, and preference for integrative or western medicine. Immediately following was a ten-point Likert scale survey that prompted the patient to rank various levels of importance in healthcare treatment preferences such as cost of care, symptom management, friend/family experiences, and reputability of the care itself. The pilot study was interpreted through an analysis of variance using an independent sample t-test. Findings suggest that factors such as associating IM as a safe and effective practice and having prior experience using IM, have a relationship with a patient's intention to use IM. The factors associated with patients’ attitudes toward the use of IM can help shape future intervention studies of interpreting which types of language used with mood/stress related disorder patients lead to an experience that involves less stigma and discrimination.


A Pilot Study of Diabetes Education Videos to Reduce Knowledge Gaps in Patients from an FQHC

The UCI Family Health Center in Santa Ana serves predominantly low-income Latinx Spanish-speaking patients, many of whom have type 2 diabetes mellitus. Physicians have limited time to assess the patient’s diabetes, their overall level of knowledge of the disease and important gaps in that knowledge. To help establish a baseline of basic diabetes knowledge, we worked with a family medicine physician to develop a two-minute educational video about diabetes–how it affects the body and how to treat it–available in English and Spanish. Two versions were created in each language—one with visuals (graphics that complement the video content) and one without visuals (only the physician talking). In this pilot study, 38 patients were randomized to view one of the two versions in their preferred language. Patients then filled out a survey where they rated their understanding of the video content and to assess their diabetes knowledge. Although this study’s small sample size did not have statistical power to detect significant differences, descriptive analysis comparing understanding and knowledge between the patients in the two video versions showed the overall level of understanding was high and knowledge was moderate. Knowledge scores were higher in participants with visuals (79.2% [SD]) versus those without visuals (72.2% [SD]), suggesting a hypothesis that visuals increase knowledge gain is worth exploring further. The main finding is that health education videos can be well-received and understandable to patients, with or without visuals. Research in this domain is important for proper patient education and improved health outcomes.

Latinx adults are more likely to have untreated hypertension (HTN) than any other race-ethnic group nationally. Medication adherence proves to be a key variable for HTN management and research is examining influences from one’s social network. An understudied social influence is health-related social control (HRSC), which focuses on interpersonal interactions that specifically entail influence and regulation. HRSC control has two main subtypes: pressure or persuasion. As such, this study aims to investigate the effects of HRSC on medication adherence in Latinx adults diagnosed with hypertension. Data was collected through a baseline questionnaire from the Mi Propio Camino study. Medication adherence was measured using Morisky Medication Adherence Scale and HRSC was assessed with ten questions regarding behaviors expressed by loved ones on a 6 point Likert scale. We ran a binary logistic regression between medication adherence and HRSC components and used participant ratings at 25th and 75th quartile to see how changes in the level of pressure and persuasion may impact medication non-adherence. We found that participants with higher levels of persuasion were more likely to be non-adherent than those reporting lower levels (p= 0.04), while pressure did not have a statistically significant relationship (p= 0.96). Additionally, 75% of participants with both low and high levels of pressure were non-adherent. Comparatively, 83% of individuals with reports of high persuasion were non-adherent, while 67% of those with reports of low persuasion were non-adherent. To better understand this relationship, we will conduct focus groups with participants to hear their direct experience.

Non-adherence to medication is very common among the Latinx population and often has detrimental impacts on patients’ lives, and may be related to the mistrust of medication and healthcare professionals. The purpose of this project is to examine the connection of patient-reported hesitancy to an objective measure of adherence to blood pressure medication among Latinx Adults with hypertension. Medication hesitancy was collected using the Beliefs About Medicines Questionnaire (BMQ), which was scored to categorize patients into high vs. low hesitancy groups.  Patients were then asked to use a digital pill-bottle cap monitor (MEMS caps) to estimate adherence by recording time stamps for everytime the bottle is opened for a 30 day monitoring period.  Nonadherence was defined as taking less than 80% of the prescribed doses over 30 days, and was compared between high hesitancy and low hesitancy groups of patients using Fisher’s exact test. In total, 44 patients (average ± SD age = 56 ± 9 years, 73% female, 98% born outside the US) completed the protocol, with 15 (34%) categorized as high hesitancy and 29 (66%) as low hesitancy.  67% of high hesitancy versus 45% low hesitancy patients exhibited nonadherence in their MEMS cap data (p=0.20).  Although not statistically significant, the magnitude of the difference is large and warrants further investigation in a larger sample to determine the association of medication hesitancy with subsequent nonadherence in this population.

Latinos are the largest minority group in the U.S. with the leading cause of death being cardiovascular disease (CVD). Previous research has shown that stress and sleep contribute to hypertension, a risk factor for CVD. However, the interplay between sleep quality and stress has not been investigated extensively as a risk factor for hypertension among Latinos. Financial stress has been associated with a higher risk for myocardial infarction and worse self-rated health. Within the study, we see if sleep quality is a protective factor against exposure to financial stress. Latino adults (n=208) were recruited from a federally qualified health center. Self-reported sleep quality in the past 7 days and current financial stress were assessed. Systolic (SBP) and diastolic (DBP) blood pressure were measured. We hypothesized that there would be a relation between financial stress and blood pressure, which would be moderated by sleep quality. We found a significant difference in sleep quality (t = 6.3, p <.001) between those with high versus low financial stress but not a difference in SBP or DBP (p > 05). We found a significant interaction between financial stress and sleep quality on DBP (F = 4.54, p = .03), wherein patients with high financial stress and low sleep quality had worse DBP (M = 86.59, SD = 13.34) than those with high financial stress and high sleep quality (M = 79.31, SD = 8.56). Our results reveal that among Latino patients, sleep quality may be protective for Latinx hypertensive patients facing financial stress.

Latinas are 40% more likely to be diagnosed with, and 30% more likely to die from cervical cancer compared to non-Latina whites. Previous research has found family support informs whether young adult Latina women obtain HPV vaccination, an effective form of cervical cancer prevention. We examined the perspective of Spanish-speaking Latina mothers about their communication on cervical cancer prevention with their daughters. A total of 12 semi-structured interviews were conducted with Latina mothers who were mostly recruited from a larger NIH-funded project, Mi Propio Camino. Questions included topics on health knowledge, their relationships with their daughters, and mothers’ level of involvement in their daughter’s health decisions. Data were analyzed with the qualitative software program Dedoose, using both deductive and inductive coding. Participants were between 45-64 years old, and 75% of them had health insurance. We found that most participants have had Pap smears in the past, did not know about the HPV test, and only a few were aware of the HPV vaccine. Themes included: limited knowledge of cervical cancer, mothers believing it's their responsibility to inform daughters about cervical cancer prevention, feelings of shame from their  Pap smear experiences, lack of access to care due to limited resources and lack of insurance, and positive mother-daughter relationships. A unique finding included some mothers' interest in daughters spreading health information to their peers. It is suggested to explore the communication among Latina siblings or peers, as an effective avenue to spread information on cervical cancer and its prevention.

Changing Minds or Following Interests? Predictors of behavior change in Latinx hypertension patients in the Mi Propio Camino study.

Managing a chronic health condition like hypertension requires adopting self management behaviors like taking medications and following a healthy lifestyle.  Health education interventions focus on encouraging participants to adopt these behaviors with mixed success.  The present study examines the degree to which the adoption of new self management behaviors observed in a health education intervention can be attributed to the interests that participants already held prior to the start of the intervention versus developing new interests during the intervention.  We are analyzing data from the Mi Propio Camino hypertension education study, in which 205 Spanish-speaking Latinx patients have completed a 4-session series of weekly group education classes.  Prior to the classes, participants completed validated questionnaires assessing level of interest in and prior adoption of six different hypertension self management behaviors (medication taking, healthy eating, physical activity, nutritional supplements, stress management and sleep hygiene).  Then in the classes, strategies to increase all of these behaviors were presented, and participants were invited to choose which behaviors they wished to adopt.  Adoption of each behavior was assessed again throughout the four week course using a daily diary, and after the final session using the same questionnaire from baseline.  Our team is currently analyzing (1) the percentage of patients that adopted each behavior, and (2) the correlation between baseline interest in a specific behavior and the likelihood of adopting that behavior.  These findings will add to the evidence on the merits of following participants’ prior interests versus introducing new strategies when designing health education interventions for Latinx hypertension patients.

Food Insecurity and Time to COVID-19 Vaccination

Latines in the U.S. have a greater risk of developing type 2 diabetes, and once diagnosed, have worse outcomes compared to other groups, often attributed to limited health literacy. To determine if diabetes health literacy is related to diabetes self-management, primarily Spanish-speaking patients (N=52) averaging 55-64 years of age were assessed through the Spoken Knowledge in Low Literacy in diabetes scale (SKILLD), a 10-item scale evaluating diabetes knowledge in patients at the UCI FQHC. SKILLD Scores were compared between patients with blood sugar (measured as hemoglobin A1c) “above target” vs. “at target” of 8.0% using an independent samples t-test. Above target patients had a mean SKILLD score of 6.2, compared to at target patients with a mean score of 5.2 (p= 0.212). Knowledge on most of the 10 items was similar between the two groups, with the exception of knowledge about symptoms of high blood sugar (answered correctly by 77 % of above target vs. 40% of at target patients; p= 0.009). This outcome might be due to increased intervention of patients with more severe diabetes. Although the sample size was limited, there is no evidence for an association between lower knowledge and poorer diabetes control. In fact, patients with higher A1cs may have as much or more knowledge as patients with lower A1c. Future studies should consider the benefits of addressing knowledge gaps alongside other factors to drive successful diabetes management, and should include larger samples with more comprehensive assessment of potential confounding variables.

COVID-19 has disproportionately impacted vulnerable populations. It is crucial to understand vaccination barriers to guide policies that address socioeconomic factors that impede vaccination uptake. Food insecurity, or the inability to meet nutritional needs, has been shown to affect access to some preventive services. Therefore, we examined the correlation between food insecurity and COVID-19 vaccination uptake. We retrospectively studied Spanish-speaking hypertensive adult patients (n = 285) in a federally qualified health center in Orange County, comparing the vaccination times of both food insecure and non-food insecure groups.We collected data from electronic health records and used survival analysis (Kaplan-Meier test) to analyze the correlation between food insecurity and time to COVID-19 vaccination. Participants mean (SD) age was 58 ± 10 and 67.6% were women. Median time for vaccination with the first dose was 106 days for both food insecure and non-food insecure participants. For the second dose median time was 28 days for the non-food insecure group while the food insecure group was 29 days. For the booster, median time for food insecure participants was 270 days and 282 days for non-food insecure participants. Time to first dose, second dose, and booster shot were similar between food insecure and food insecure patients (all p’s>0.05), indicating no significant difference between groups. The lack of influence food insecurity has on vaccination timing is a significant finding, indicating the need to allocate resources to other socioeconomic factors that have a greater impact on vaccination uptake and by extension implementing more effective policies.

Medication nonadherence contributes to disparities in chronic disease outcomes among Latinx communities. Prior research shows that the Safran Reasons for Nonadherence Scale (SRNS) is a valid predictor of health outcomes for Latinx adults with diabetes. We examined the validity of expanding the use of the SRNS to predict successful hypertension management. Spanish-speaking adult hypertension patients were invited to monitor their medication adherence using a pill bottle cap monitor (MEMS cap) that recorded every time the bottle was opened for a 30 day period. After 30 days, MEMS caps were collected, blood pressure (BP) was measured and the SRNS was collected for each patient. Participants were categorized as “Self-reported adherent” or “Self-reported nonadherent” based on SRNS responses. Objective nonadherence was defined from MEMS data as <80% of prescribed doses taken, and was compared between the self-reported adherent versus nonadherent groups using Fisher’s exact test. BP was compared between adherent versus nonadherent patients for both measures with independent samples t-tests. Of the 44 participants completing the study, self-reported adherent (N=15) versus nonadherent (N=29) patients did not differ in objective nonadherence rates (53% vs. 52%, respectively; p=0.99). BP did not differ between self-reported adherence groups, but systolic BP was significantly higher among objective nonadherent vs. adherent patients (150±19mmHg vs. 128±12mmHg; p<0.001). Although the sample size is limited, there is no strong evidence that the SRNS is a valid predictor of objective nonadherence or BP, but objective nonadherence measured by MEMS caps is highly predictive of BP.

Spanish-speaking, Latinx adults with hypertension are disproportionately affected by poor blood pressure control linked to lower uptake of recommended management strategies and less access to culturally and linguistically appropriate services. Group health education classes offered in Spanish and focused on peer support and individualized goal setting may help improve management behaviors and outcomes. In a longitudinal, observational study, we examined changes in knowledge, attitudes, behaviors, and blood pressure among Spanish-speaking Latinx hypertensive patients from the UCI Family Health Center in Santa Ana participating in four weekly classes. A total of 44 females and 16 males averaging 56 years of age participated. Surveys and blood pressure measurements were collected pre and post-intervention, with pre to post changes examined with paired t-tests for continuous variables and McNemar’s test for categorical variables. Knowledge scores did not change significantly, but attitudes towards blood pressure management improved, with the proportion of patients reporting negative beliefs about medications dropping from 71.1% to 40.0% (p=0.003). There were modest increases in health behaviors, including an increase in patients engaging in breathing exercises to reduce stress from 50% to 82% (p=0.022). Marginal blood pressure changes were observed for average (±SD) systolic (pre: 142 ± 17mmHg vs. post: 138 ± 14mmHg; p=0.065) and diastolic (pre: 85 ± 10mmHg, post: 83± 9mmHg; p=0.103) readings. These findings suggest that group health education classes offered in Spanish can promote positive attitudes about behavior change even if knowledge ratings do not change significantly.

Patients' ability to attend appointments is vital for managing their chronic illness and overall preventing more serious health outcomes. Transportation may act as a barrier to healthcare access within the Latinx community, especially patients who lack control over their transportation. Latinx patients with hypertension who see healthcare providers at an FQHC in Santa Ana completed a questionnaire as a part of an NIH-funded study. A multivariable adjusted model indicated that distance was not statistically significant (p-value = 0.61) in not attending hypertension health classes. However, this study highlights and validates a patient’s journey to receiving care, as transportation is oftentimes overlooked when a patient attends their visit. Of the patients that completed the questionnaire (n=284), there were 90 males and 192 females, with a mean age of 58.2 (± 9.98). For patients that relied on another person to drop them off (n=25), 12% were male and 88% were female. For patients that rely on transportation (n=17), 11.8% had an income above $20,000 and 70.5% had an income below $20,000. This suggests that gender and income influence how much autonomy patients have with their transportation, which may act as a barrier for healthcare access within the Latinx community. However, this data is limited to Orange County and is not representative of the whole Latinx community. Therefore, data should be collected beyond Santa Ana to better understand how transportation could act as a barrier for the Latinx community in managing chronic illness(es).

Marginalized groups in the United States encounter barriers that prevent their access to healthcare. The aim of this study is to better understand what influences patients’ motives to attend in-person health education classes. Participants were recruited for the Mi Propio Camino (MPC) study and completed a baseline questionnaire that collects data on their demographics, beliefs about medications, food insecurity, readiness to change, and attitudes between patient and provider interactions. Data on patient attendance for at least one MPC class was collected using RedCap. Upon bivariate analyses, there were a total of 284 participants with an average age of 58.24 (± 9.98) and composed of 60% of female participants. The only significant variable associated with class attendance was patients’ readiness to change (RTC). The RTC data collected considered changes in multiple healthy lifestyle strategies, and for every 1 point increase in RTC score, participants were twice as likely to attend an MPC class. Notably, age (p-value= 0.013), distance (p-value=0.61) to the intervention site, and food insecurity (p-value=0.14) were not significant predictors of class attendance. These findings suggest that readiness to change plays a significant role when participants are deciding whether to attend educational classes. Research can be done to further understand ways to increase patient attendance, for instance, participants' perception of RTC values.

Since the COVID-19 vaccine’s public release, there has been a drop in cases, signifying its importance in protecting our communities. Prior research indicates correlation between medication avoidance and influenza vaccine hesitancy. Therefore, we aim to explore disparities in vaccination by investigating the relationship between medication beliefs and the time to receiving COVID-19 vaccinations, to evaluate for a similar trend. In this study, responses from the Beliefs about Medication Questionnaire (BMQ) and medical records of 283 Spanish-speaking hypertensive adult patients (mean (SD) age = 58 (10)) at UCI FQHC in Santa Ana, CA were collected prior to 06/01/2021, when COVID-19 vaccines became widely available. Unadjusted survival analysis via the Kaplan-Meier test evaluated patient beliefs of the necessity and potential harms of medication to determine any differences in vaccination status between those with positive (necessity>concerns), neutral (concerns=necessity) or negative (concerns>necessity) medication beliefs. Median time to first dose, full vaccination and booster from administration of previous dose were 106, 28 and 243 days, respectively. In comparing time to event with medication beliefs, there was a marginal association between the three groups of medication beliefs and their time to the first dose (median time = 98, 106, and 115 for positive, neutral and negative groups, respectively; p=0.073), second dose (p=0.92), and booster dose (p=0.65). These findings show that medication beliefs alone may not differentiate time to COVID vaccination. Further research can analyze different measures of medication beliefs and co-variables in order to address health disparities.

Current biomedical research lacks minority participation specifically from the Hispanic/Latino community. By one estimate, only 1% of Latinos participate in clinical trials. The All of Us Research Program funded by the NIH seeks to create a diverse and inclusive medical data set from one million or more participants in the United States to advance precision medicine, and aims to include communities that are underrepresented in biomedical research like the Hispanic/Latino community. In this study, we are conducting focus groups to understand why Hispanics/Latinos are hesitant to participate in biomedical research. We anticipate that mistrust among healthcare providers and investigators, as well as limited formal education among participants, may be barriers negatively impacting participation in biomedical research. Currently, one focus group has been conducted. 12 Spanish speaking participants, with an average age of 57.6 + 10.7 ranging from 38 to 72 years, were recruited from a health care clinic in Santa Ana, California. A brief overview of the All of Us study was provided and the participants were asked questions regarding the benefits, risks, and requirements of biomedical research participation. Preliminary qualitative analysis of transcripts from the focus group suggest themes of mistrust, fear of manipulation, concerns about the personal benefits of participating, and lack of knowledge about the research protocol were identified. Additional focus groups will be conducted to triangulate the findings. The preliminary results suggest that barriers to participation may be better understood and addressed through community engagement processes focused on engendering trust.
