Health literacy is generally low in marginalized groups, leading to delays in accessing care, poor health outcomes, and health disparities. Yet, some individuals in these groups demonstrate higher health literacy and better health outcomes. These exceptional cases exemplify 'positive deviance' because they have found ways to be successful where others have not. Identifying the methods, practices, and resources that these individuals have used to gain health literacy and healthcare access may have generalized application to improve health literacy, access to care, and health outcomes. Using the Integrated Model of Health Literacy, the main objectives of this study are to (1) identify facilitators, barriers, and strategies to gain sexual and reproductive health literacy and healthcare access and (2) to explore each of the core domains of health literacy as they relate to successful access of sexual and reproductive healthcare services among individuals identified as positive deviants. For the purposes of this mixed methods community engaged study, positive deviants are defined as Mexican American young women aged 18-29 years old living in Rural Western New York who have accessed sexual and reproductive healthcare within the past year. A community advisory committee will be formed to provide community-engaged guidance and support for the recruitment of participants. Positive deviants will participate in a survey and semi-structured interview. Data collection and analysis will be simultaneous and iterative. Results will provide evidence of positive deviant methods, practices, and strategies to gain health literacy and access to sexual and reproductive healthcare. Findings may reveal characteristics and patterns in the relationship of health literacy and healthcare access that can inform interventions to improve health literacy and make healthcare more accessible for this demographic group and context.

BACKGROUND: Health disparities in osteoarthritis (OA) outcomes exist both in the occurrence and treatment of functional limitation and disability for Mexican Americans. Although the effect of self-management of chronic illness is well established, studies demonstrate little attention to self-management of function or disability, despite the strong potential effect on both and, consequently, on patients' lives. OBJECTIVE: The purpose of this study pilot was to develop and test key variable relationships for a measure of disability self-management among Mexican Americans. METHODS: In this sequential, two-phased, mixed-methods, biobehavioral pilot study of Mexican American women and men with OA, a culturally tailored measure of disability self-management was created, and initial relationships among key variables were explored. RESULTS: First, a qualitative study of 19 adults of Mexican American descent born in Texas (United States) or Mexico was conducted. The Mexican American Disability Self-Management Scale was created using a descriptive content analysis of interview data. The scale was tested and refined, resulting in 18 items and a descriptive frequency of therapeutic management efforts. Second, correlations between study variables were estimated: Disability and function were negatively correlated. Disability correlated positively with social support and activity effort. Disability correlated negatively with disability self-management, pain, and C-reactive protein. Function was positively correlated with age, pain, and depression. Liver enzymes (alanine transaminase) correlated positively with pain and anxiety. DISCUSSION: This mixed-methods study indicates directions for further testing and interventions for disability outcomes among Mexican Americans.

AIMS: Three smoking cessation studies (CARE, Break Free, Por Nuestra Salud [PNS]) were used to measure changes in average alcohol consumption, binge drinking and alcohol-related problems during a smoking cessation attempt and to explore co-action with smoking abstinence. DESIGN: CARE and PNS were longitudinal cohort cessation studies; Break Free was a two-arm randomized clinical trial. SETTING: Texas, USA. PARTICIPANTS: Participants were current smokers who were recruited from the community and received smoking cessation interventions. All participants received nicotine replacement therapy and smoking cessation counseling. CARE included 424 smokers (1/3 White, 1/3 African American and 1/3 Latino); Break Free included 399 African American smokers; PNS included 199 Spanish-speaking Mexican-American smokers. MEASUREMENTS: Weekly alcohol consumption was collected multiple times pre and post-quit, and binge drinking and alcohol-related problems were collected at baseline and 26 weeks post-quit. Analyses included only those who indicated current alcohol use. FINDINGS: Average alcohol consumption decreased from baseline to 26 weeks post-quit in CARE (F = 17.09, P < 0.001), Break Free (F = 12.08, P < 0.001) and PNS (F = 10.21, P < 0.001). Binge drinking decreased from baseline to 26 weeks post-quit in CARE (F = 3.94, P = 0.04) and Break Free (F = 10.41, P < 0.001) but not PNS. Alcohol-related problems decreased from baseline to 26 weeks post-quit in CARE (Chi-sq = 6.41, P = 0.010) and Break Free (Chi sq = 14.44, P = 0.001), but not PNS. CONCLUSIONS: Among current drinkers, alcohol use/problems appear to decrease during a smoking cessation attempt and remain low through 26 weeks after the quit attempt. Little evidence was found for co-action, with smoking abstainers and relapsers showing similar change in alcohol use/problems.

PURPOSE: To examine the association of a traditional Mexican diet score with risk of total, breast, and colorectal cancer among women of Mexican ethnic descent in the Women's Health Initiative (WHI). METHODS: Participants were WHI enrollees who self-identified as being of Mexican descent. Data from food frequency questionnaires self-administered at study baseline were used to calculate the MexD score, with higher scores indicating greater adherence to an a priori-defined traditional Mexican diet (high in dietary fiber, vegetables, and legumes). Incident cancers were self-reported by participants from 1993 to 2020 and adjudicated by trained physicians. We used multivariable-adjusted Cox proportional hazards models to calculate hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS: Among 2,343 Mexican descent women (median baseline age: 59 years), a total of 270 cancers (88 breast, 37 colorectal) occurred during a mean follow-up of 14.4 years. The highest tertile of MexD score was associated with a lower risk of all-cancer incidence (HR: 0.67; 95% CI 0.49-0.91; p-trend: 0.01) and colorectal cancer (HR: 0.38; 95% CI 0.14-0.998; p-trend < 0.05), with each unit increase in the MexD score associated with a 6% lower risk of all-cancer incidence (HR: 0.94; 95% CI 0.88-0.99). There was no statistically significant association with risk of breast cancer. CONCLUSION: Consumption of a traditional Mexican diet was associated with a significantly lower risk of all-cancer incidence and colorectal cancer. Confirmation of these findings in future studies is important, given the prevalence of colorectal cancer and a growing U.S. population of women of Mexican descent.

We examined the relationship between vision impairment (VI) and new-onset frailty among non-frail Mexican American older adults (≥70 years) at baseline and determined the differential impact of VI on each frailty criteria. Data were from an 18-year prospective cohort from the Hispanic Established Population for the Epidemiologic Study of the Elderly (1998/1999, N = 1072 to 2016, N = 175). Frailty was defined as ≥3 criteria: unintentional weight loss of >10 pounds, weakness, exhaustion, low physical activity, and slowness. VI was defined as difficulty in recognizing a friend at arm's length's away, across the room, or across the street. We found that participants with VI (near or distant) and distant VI had greater odds of frailty (near or distant VI, OR = 1.89, 95% CI = 1.30-2.73 and distant VI, OR = 1.95, 95% CI = 1.34-2.86, respectively) after controlling for covariates over time. Early screening (optimal management) of VI may prevent or delay onset of frailty among older Mexican Americans.

BACKGROUND: We explored whether the reported racial differences in subclinical myocardial injury (SCMI) are due to variations in the prevalence or differential impact of the SCMI risk factors. METHODS: This analysis included 3074 Whites, 1337 Blacks, and 1441 Mexican Americans from the Third National Health and Nutrition Examination Survey who were free of cardiovascular disease. SCMI was defined from standard electrocardiograms as a cardiac infarction/injury score ≥ 10 points. Multivariable logistic regression analysis was used to assess the association of SCMI with its risk factors stratified by race. Multiplicative interaction between each risk factor and race was also examined. RESULTS: Overall prevalence of SCMI was 20.3%, with Mexican Americans exhibiting a lower prevalence than Whites and Blacks (16.5%, 20.4%, and 20.7%, respectively). Whites had more prevalence of dyslipidemia and smoking. Mexican Americans had more diabetes, while Blacks had more hypertension, obesity, and left ventricular hypertrophy. Significant risk factors for SCMI were older age, lower income (<20 K), smoking, diabetes, and no regular exercise. The association of SCMI with age was more pronounced in Mexican Americans (p-value for interaction 0.03), whereas the associations of SCMI with smoking, no-regular exercise, and diabetes were stronger in Whites (p-value for interaction 0.04, 0.001, 0.007, respectively). CONCLUSIONS: Heterogeneity in the racial differences in the prevalence of SCMI risk factors exists, but they do not explain racial differences in SCMI. The stronger associations of smoking, diabetes, and no regular exercise with SCMI partially explain the higher prevalence of SCMI in Whites.

BACKGROUND: The National Institutes of Health has advocated for improved minority participation in clinical research, including clinical trials and observational epidemiologic studies since 1993. An understanding of Mexican Americans (MAs) participation in clinical research is important for tailoring recruitment strategies and enrollment techniques for MAs. However, contemporary data on MA participation in observational clinical stroke studies are rare. We examined differences between Mexican Americans (MAs) and non-Hispanic whites (NHWs) participation in a population-based stroke study. METHODS: We included 3,594 first ever stroke patients (57.7% MAs, 48.7% women, median [IQR] age 68 [58-79]) from the Brain Attack Surveillance in Corpus Christi Project, 2009-2020 in Texas, USA, who were approached and invited to participate in a structured baseline interview. We defined participation as completing a baseline interview by patient or proxy. We used log-binomial models adjusting for prespecified potential confounders to estimate prevalence ratios (PR) of participation comparing MAs with NHWs. We tested interactions of ethnicity with age or sex to examine potential effect modification in the ethnic differences in participation. We also included an interaction between year and ethnicity to examine ethnic-specific temporal trends in participation. RESULTS: Baseline participation was 77.0% in MAs and 64.2% in NHWs (Prevalence Ratio [PR] 1.20; 95% CI, 1.14-1.25). The ethnic difference remained after multivariable adjustment (1.17; 1.12-1.23), with no evidence of significant effect modification by age or sex (Pinteraction by age = 0.68, Pinteraction by sex = 0.83). Participation increased over time for both ethnic groups (Ptrend < 0.0001), but the differences in participation between MAs and NHWs remained significantly different throughout the 11-year time period. CONCLUSION: MAs were persistently more likely to participate in a population-based stroke study in a predominantly MA community despite limited outreach efforts towards MAs during study enrollment. This finding holds hope for future research studies to be inclusive of the MA population.

BACKGROUND: Thyroid disease is a prominent endocrine disorder, yet the clinical epidemiology of this condition remains unclear. This study aims to describe the recent trends in the prevalence of thyroid disease in US adults from 1999-2018. METHODS: This cross-sectional study used nationally representative data collected through the National Health and Nutrition Examination Survey (NHANES) from January 1, 1999 to December 31, 2018. Patients with thyroid disease were defined as patients who reported having a thyroid disease and were on thyroid-related treatment. Age-standardized prevalence of thyroid disease was calculated within 4-year survey periods (1999-2002, 2003-2006, 2007-2010, 2011-2014, and 2015-2018). RESULTS: During the NHANES 1999-2018, a total of 57 540 participants were examined. The age-standardized prevalence of thyroid disease was 5.05% (95% CI, 4.55%-5.60%) from 2015-2018, signifying a significant increase from the 1999-2002 period (P <.0002). However, prevalent thyroid disease remained steady between 2003 and 2014. The highest prevalence of thyroid disease was observed in non-Hispanic Whites (8.1%; 95% CI, 7.3%-9.0%), individuals aged ≥60 years (15.4%; 95% CI, 13.3%-17.8%), and tended to be higher in women (7.6%; 95% CI, 6.8%-8.5%). Multiple regression analysis revealed that age, women sex, non-Hispanic White and Mexican American, body mass index, higher education and incomes were independently associated with increased risks of thyroid disease. CONCLUSION: The age-standardized prevalence of thyroid disease among US adults increased from 1999-2003, remained stable between 2003 and 2014, and then saw an increase from 2014-2018, with the highest rate observed among elders, women, and non-Hispanic Whites.

Using baseline data from three partnering federally qualified health centers, we examined factors associated with depressive symptoms among Mexican-origin adults at risk of chronic disease living in three counties in Southern Arizona (i.e., Pima, Yuma, and Santa Cruz). Multivariable linear regression models identified correlates of depressive symptoms for this population controlling for sociodemographic characteristics. Among 206 participants, 85.9% were female and 49% were between 45 and 64 years of age. The proportion of depressive symptoms was 26.8%. Low levels of physical pain and high levels of hope and social support were also reported. Physical pain was positively and significantly related to depressive symptoms (ß = 0.22; 95% CI = 0.13, 0.30). Conversely, hope was negatively and significantly associated with depressive symptoms (ß = -0.53; 95% CI = -0.78, -0.29). A better understanding of factors related to depressive symptoms among Mexican-origin adults is necessary to fulfill their mental health needs, as well as to achieve health equity and to eliminate health disparities in the US-Mexico border region.

Diabetes is the seventh leading cause of death in the United States, and it is particularly problematic among the Latine population. This study employed multivariable logistic regression models to examine how hypertension, depression, and sociodemographics were associated with diabetes in a cross-sectional sample of Mexican-origin adults living in three counties of Southern Arizona. The overall prevalence of diabetes from this primary care sample was 39.4%. Holding covariates at fixed values, individuals having hypertension were 2.36 (95% CI: 1.15, 4.83) times more likely to have diabetes, when compared to individuals not having hypertension. The odds of having diabetes for individuals with ≥12 years of educational attainment were 0.29 (95% CI: 0.14, 0.61) times the corresponding odds of individuals with <12 years of educational attainment. For individuals with depression, the odds of having diabetes for those who were born in Mexico and had <30 years living in the US were 0.04 (95% CI: 0, 0.42) times the corresponding odds of individuals without depression and who were born in the US. Findings suggest clinical and public health systems should be aware of the potential increased risk of diabetes among Mexican-origin adults with hypertension and lower educational attainment.

Racial and ethnic disparities in COVID-19 incidence are pronounced in underserved U.S./Mexico border communities. Working and living environments in these communities can lead to increased risk of COVID-19 infection and transmission, and this increased risk is exacerbated by lack of access to testing. As part of designing a community and culturally tailored COVID-19 testing program, we surveyed community members in the San Ysidro border region. The purpose of our study was to characterize knowledge, attitudes, and beliefs of prenatal patients, prenatal caregivers, and pediatric caregivers at a Federally Qualified Health Center (FHQC) in the San Ysidro region regarding perceived risk of COVID-19 infection and access to testing. A cross-sectional survey was used to collect information on experiences accessing COVID-19 testing and perceived risk of COVID-19 infection within San Ysidro between December 29, 2020 and April 2, 2021. A total of 179 surveys were analyzed. Most participants identified as female (85%) and as Mexican/Mexican American (75%). Over half (56%) were between the age of 25 and 34 years old. Perceived Risk: 37% reported moderate to high risk of COVID-19 infection, whereas 50% reported their risk low to none. Testing Experience: Approximately 68% reported previously being tested for COVID-19. Among those tested, 97% reported having very easy or easy access to testing. Reasons for not testing included limited appointment availability, cost, not feeling sick, and concern about risk of infection while at a testing facility. This study is an important first step to understand the COVID-19 risk perceptions and testing access among patients and community members living near the U.S./Mexico border in San Ysidro, California.


COVID-19 testing strategies that fail to incorporate culturally competent methods to reach traditionally underserved communities can lead to persistent transmission and increased infection rates. During the early stages of the COVID-19 pandemic, we surveyed 179 people living in a community with high burden of COVID-19 infection about their perception of infection risk and their experiences accessing testing. Capturing and understanding these community perceptions on COVID-19 risk are vital when developing a testing program that is accessible and appropriate for the target population. In our study, we found half of survey respondents thought their risk of COVID-19 infection as low to none and over half of respondents stated they had already been tested for COVID-19. These findings provide insight to the beliefs of individuals who live and seek health care in communities with high rates of COVID-19 infection and will help guide the design and implementation of culturally tailored testing strategies.

Secular trends in earlier initiation of puberty have been observed in recent decades. One risk factor appears to be increases in adiposity, as measured by body mass index. This trend is particularly notable among Latino populations, who have higher rates of overweight/obesity compared with non-Latino White youth. Previous research has focused primarily on White girls, resulting in data gaps regarding male puberty and among potentially high-risk populations. Using data from the Center for the Health Assessment of Mothers and Children of Salinas (CHAMACOS) study, we examined body mass index at age 5 years (2005-2006) and multiple markers of pubertal onset, assessed repeatedly and longitudinally at 7 in-person visits, starting at age 9 and continuing through age 14 (2009-2015), among 336 Mexican Americans in Salinas, California. We observed no associations among boys, but found significantly earlier thelarche in overweight (HR = 1.7, 95% CI: 1.1, 2.7) and obese girls (HR = 1.5, 95% CI: 1.0, 2.4), menarche in overweight girls (HR = 1.6; CI: 1.0, 2.4), and pubarche in obese girls (HR = 1.9; CI: 1.2, 3.0), compared with normal-weight girls. This study examined an understudied population and included key covariates, such as birth weight and early adverse events, which are typically omitted in studies.

INTRODUCTION: Representation of Mexican Americans in Alzheimer's disease (AD) clinical research has been extremely poor. METHODS: Data were examined from the ongoing community-based, multi-ethnic Health & Aging Brain among Latino Elders (HABLE) study. Participants underwent functional exams, clinical labs, neuropsychological testing, and 3T magnetic resonance imaging of the brain. Fasting proteomic markers were examined for predicting mild cognitive impairment (MCI) and AD using support vector machine models. RESULTS: Data were examined from n = 1649 participants (Mexican American n = 866; non-Hispanic White n = 783). Proteomic profiles were highly accurate in detecting MCI (area under the curve [AUC] = 0.91) and dementia (AUC = 0.95). The proteomic profiles varied significantly between ethnic groups and disease state. Negative predictive value was excellent for ruling out MCI and dementia across ethnic groups. DISCUSSION: A blood-based screening tool can serve as a method for increasing access to state-of-the-art AD clinical research by bridging between community-based and clinic-based settings.

Emerging research suggests associations of physical and psychosocial stressors with epigenetic aging. Although this work has included early-life exposures, data on maternal exposures and epigenetic aging of their children remain sparse. Using longitudinally collected data from the California, Salinas Valley CHAMACOS study, we examined relationships between maternal Adverse Childhood Experiences (ACEs) reported up to 18 years of life, prior to pregnancy, with eight measures (Horvath, Hannum, SkinBloodClock, Intrinsic, Extrinsic, PhenoAge, GrimAge, and DNAm telomere length) of blood leukocyte epigenetic age acceleration (EAA) in their children at ages 7, 9, and 14 years (N = 238 participants with 483 observations). After adjusting for maternal chronological age at delivery, pregnancy smoking/alcohol use, parity, child gestational age, and estimated leukocyte proportions, higher maternal ACEs were significantly associated with at least a 0.76-year increase in child Horvath and Intrinsic EAA. Higher maternal ACEs were also associated with a 0.04 kb greater DNAm estimate of telomere length of children. Overall, our data suggests that maternal preconception ACEs are associated with biological aging in their offspring in childhood and that preconception ACEs have differential relationships with EAA measures, suggesting different physiologic utilities of EEA measures. Studies are necessary to confirm these findings and to elucidate potential pathways to explain these relationships, which may include intergenerational epigenetic inheritance and persistent physical and social exposomes.

Hepatic steatosis (HS) is a growing problem in adults worldwide, with racial/ethnic disparity in the prevalence of the disease. The purpose of this study was to characterize the racial/ethnic prevalence of the stages (normal/mild [S0/S1], moderate [S2], and severe [S3]) of HS in Mexican Americans and other Hispanics compared to other racial/ethnic groups. We analyzed data for 5,492 individuals 12 years and older from the newly released National Health and Nutrition Examination Survey 2017-2018, which is a representative sample of the US adult population. HS was diagnosed by FibroScan using controlled attenuation parameter values: S0, <238; S1, 238-259; S2, 260-290; S3, >290. We analyzed the data using the bivariate chi-squared test and multinomial regression. The prevalence of HS overall was 46.9% (S2,16.6%; S3, 30.3%). The prevalence of S3 was highest among Mexican Americans (42.8%), lowest among Blacks (21.6%), 27.6% in other Hispanics, and 30.6% in Whites (P < 0.05). Mexican Americans were about 2 times more likely than Whites to have S2 and S3, while other Hispanics showed no difference from Whites. In an adjusted model, the common risk factors of S2 and S3 were male sex, older ages, high waist-to-hip ratio, body mass index ≥25, and high triglycerides (P < 0.05). Other risk factors for S3 were hemoglobin A1c ≥5.7 and highly sensitive C-reactive protein ≥10 mg/dL (P < 0.05). Conclusion: Our study challenges the paradigm that HS is higher in Hispanics overall; rather, our data show that HS is higher in Mexican Americans and not non-Mexican American Hispanics.

BACKGROUND: Hispanic older adults are a high-risk population for Alzheimer's disease and related dementias (ADRD) but are less likely than non-Hispanic White older adults to have ADRD documented as a cause of death on a death certificate. OBJECTIVE: To investigate characteristics associated with ADRD as a cause of death among Mexican-American decedents diagnosed with ADRD. METHODS: Data came from the Hispanic Established Populations for the Epidemiologic Study of the Elderly, Medicare claims, and National Death Index. RESULTS: The final sample included 853 decedents diagnosed with ADRD of which 242 had ADRD documented as a cause of death. More health comorbidities (OR = 0.40, 95% CI = 0.28-0.58), older age at death (OR = 1.18, 95% CI = 1.03-1.36), and longer ADRD duration (OR = 1.08, 95% CI = 1.03-1.14) were associated with ADRD as a cause of death. In the last year of life, any ER admission without a hospitalization (OR = 0.45, 95% CI = 0.22-0.92), more physician visits (OR = 0.96, 95% CI = 0.93-0.98), and seeing a medical specialist (OR = 0.46, 95% CI = 0.29-0.75) were associated with lower odds for ADRD as a cause of death. In the last 30 days of life, any hospitalization with an ICU stay (OR = 0.55, 95% CI = 0.36-0.82) and ER admission with a hospitalization (OR = 0.67, 95% CI = 0.48-0.94) were associated with lower odds for ADRD as a cause of death. Receiving hospice care in the last 30 days of life was associated with 1.98 (95% CI = 1.37-2.87) higher odds for ADRD as a cause of death. CONCLUSION: Under-documentation of ADRD as a cause of death may reflect an underestimation of resource needs for Mexican-Americans with ADRD.

OBJECTIVE: Racial/ethnic minorities face unique stressors, including perceived discrimination (PD), that may increase the difficulty of quitting smoking relative to the general population of smokers. The current study examines the impact of acute PD on smoking lapse during a quit attempt, as well as potential mechanisms linking PD to lapse among Spanish-speaking Mexican Americans. METHOD: Participants (N = 169) were Spanish-speaking Mexican Americans living in the United States who completed ecological momentary assessments (EMAs) multiple times per day for 21 days postquit. A multilevel structural equation model decomposed the effect of PD on smoking lapse into indirect effects through negative affect, positive affect, smoking urge, motivation to quit, and self-efficacy. RESULTS: Results indicated that PD operated indirectly through negative affect, positive affect, and urge to smoke, above and beyond other mechanisms, to increase risk for smoking lapse. CONCLUSIONS: Findings have direct implications for intervention development among this population, including the potential for developing strategies to buffer the impact of PD, as well as skills to directly manage increased negative affect and urge to smoke. Just-in-time adaptive interventions (JITAIs) might be particularly useful, given they are designed to deliver treatment in real-time (e.g., delivery of strategies to build resilience and implement coping strategies) that could counter the impact of PD on smoking lapse.

CONTEXT: The body mass index (BMI) and waist circumference (WC) as diagnostic tools of obesity do not reflect the same level of fat mass and whether obesity leads to various effects on cardiometabolic risk factors among different racial/ethnic population is unknown. OBJECTIVE: The study aims to address the multicollinearity between BMI and WC by using the residual model approach and to assess and compare the effects of obesity metrics on cardiometabolic risk factors among different races/ethnicities. DESIGN, SETTING, AND PARTICIPANTS: Data from a nationally representative sample of mainland Chinese adults collected in 2010 and data from the National Health and Nutrition Evaluation Survey 2005-2016 were used. By conducting a regression analysis between WC and BMI, the variation of BMI was removed from WC measures and residual of WC was obtained. The associations between obesity metrics and cardiometabolic risk factors were compared among different races/ethnicities by sex. RESULTS: The residual WC was significantly associated with all the cardiometabolic risk factors in mainland Chinese, and most of the factors in non-Hispanic white and non-Hispanic black adults, but not in the other races/ethnicities. The standardized regression coefficients of the associations between obesity metrics and cardiometabolic factors showed that the obesity metrics had greater impact on systolic blood pressure, diastolic blood pressure, and triglyceride in Chinese adults than those of other racial/ethnic groups. CONCLUSIONS: Chinese adults are more susceptible to the effects of overall obesity and fat distribution on cardiometabolic risk factors than the other racial/ethnic population.

PURPOSE: Among healthy postmenopausal women, levels of CA125 and CA15.3 are influenced by demographic and reproductive factors, including race/ethnicity. In this study, we sought to examine the interaction between race/ethnicity and other correlates of these biomarkers and whether the racial differences observed are simply determined by other correlates with racial differences. METHODS: In archived sera from 946 postmenopausal women who participated in the 2001-2002 cycle of the National Health and Nutrition Examination Survey, we measured CA125 and CA15.3 and examined their associations with health survey and examination data available in this cohort. We used multivariable linear regression to examine the association between CA125 and CA15.3 and race/ethnicity. We then calculated geometric means of these markers by demographic and reproductive factors stratified by race/ethnicity and used likelihood ratio tests to evaluate heterogeneity. RESULTS: Non-white race was associated with lower CA125, with Non-Hispanic Black women being associated with - 29.0% (95% CI - 42.5%, - 12.2%) difference and Mexican American women being associated with - 6.4% (95% CI - 18.1%, 6.9%) difference on average compared to Non-Hispanic White women. Associations between CA125 and age and parity varied by race/ethnicity. Non-Hispanic Black women were associated with higher CA15.3 compared to Non-Hispanic White women, with 17.3% (95% CI - 0.5%, 38.3%) differences on average. Associations between CA15.3 and age, number of births, and age at natural menopause varied by race/ethnicity. CONCLUSIONS: Among postmenopausal women, Non-Hispanic Black women were associated with lower CA125 and higher CA15.3 levels compared to Non-Hispanic White women. Our results support that race/ethnicity should be considered when assigning thresholds for these biomarkers being tested for diagnostic or screening purposes.

OBJECTIVE: To investigate perspectives of diabetes, nutrition, and health among underrepresented Mexican-origin males and elucidate on contributing factors of type 2 diabetes disparities. RESEARCH DESIGN: Audio-recorded, semi-structured interviews were conducted with 15 native Spanish-speaking, Mexican-origin males. Men were between the ages of 40 and 64 and at risk for type 2 diabetes-defined as > 40 years of age, BMI > 25, and sedentary over the last 3 months. Data collected included clinical measures (height, weight, waist circumference, blood pressure) and demographic characteristics (years living in the U.S., marital status, employment, occupational physical activity, income, educational attainment, and average physical activity levels). The audio recordings, each lasting approximately 60 min, were transcribed verbatim and underwent three-cycle coding with analysis for codebook formation, categorization, and thematic extraction. RESULTS: Barriers to engaging in health behaviors among Mexican-origin males include poor understanding of diabetes and nutrition, unreliable sources of health information, and socioeconomic status. Enablers of health neglect include intense perceptions of diabetes severity and a reactive health culture rooted in medical machismo and valemadrismo. Perspectives of personal responsibility and the desire to learn through culturally specific recommendations detail potential facilitators of health behaviors. CONCLUSION: The data convey a network of sociocultural factors that inhibit health prioritization and promote disease misconceptions among Mexican-origin males. Pragmatic, culturally tailored education represents serviceable strategies for health promotion and diabetes prevention. These findings explicate cultural considerations for educators and clinicians seeking optimization of programs and clinical interactions with Mexican-origin men.
