Cumulative All-Cause Mortality in Diverse Hispanic/Latino Adults : A Prospective, Multicenter Cohort Study.

BACKGROUND: All-cause mortality among diverse Hispanic/Latino groups in the United States and factors underlying mortality differences have not been examined prospectively. OBJECTIVE: To describe cumulative all-cause mortality (and factors underlying differences) by Hispanic/Latino background, before and during the COVID-19 pandemic. DESIGN: Prospective, multicenter cohort study. SETTING: Hispanic Community Health Study/Study of Latinos. PARTICIPANTS: 15 568 adults aged 18 to 74 years at baseline (2008 to 2011) of Central American, Cuban, Dominican, Mexican, Puerto Rican, South American, and other backgrounds from the Bronx, New York; Chicago, Illinois; Miami, Florida; and San Diego, California. MEASUREMENTS: Sociodemographic, acculturation-related, lifestyle, and clinical factors were assessed at baseline, and vital status was ascertained through December 2021 (969 deaths; 173 444 person-years of follow-up). Marginally adjusted cumulative all-cause mortality risks (11-year before the pandemic and 2-year during the pandemic) were examined using progressively adjusted Cox regression. RESULTS: Before the pandemic, 11-year cumulative mortality risks adjusted for age and sex were higher in the Puerto Rican and Cuban groups (6.3% [95% CI, 5.2% to 7.6%] and 5.7% [CI, 5.0% to 6.6%], respectively) and lowest in the South American group (2.4% [CI, 1.7% to 3.5%]). Differences were attenuated with adjustment for lifestyle and clinical factors. During the pandemic, 2-year cumulative mortality risks adjusted for age and sex ranged from 1.1% (CI, 0.6% to 2.0%; South American) to 2.0% (CI, 1.4% to 3.0%; Central American); CIs overlapped across groups. With adjustment for lifestyle factors, 2-year cumulative mortality risks were highest in persons of Central American and Mexican backgrounds and lowest among those of Puerto Rican and Cuban backgrounds. LIMITATION: Lack of data on race and baseline citizenship status; correlation between Hispanic/Latino background and site. CONCLUSION: Differences in prepandemic mortality risks across Hispanic/Latino groups were explained by lifestyle and clinical factors. Mortality patterns changed during the pandemic, with higher risks in persons of Central American and Mexican backgrounds than in those of Puerto Rican and Cuban backgrounds.

Associations between sodium, potassium, and blood pressure: results from the Hispanic Community Health Study/Study of Latinos, a prospective cohort study.

BACKGROUND: Although the subject of numerous studies, the associations between dietary sodium, potassium, and the ratio of dietary sodium to potassium with blood pressure are not clear-cut. In addition, there is a paucity of research on these relationships in prospective cohort studies with representation from diverse Hispanic/Latino adults. OBJECTIVES: To evaluate the associations between dietary intake of sodium, potassium, and the ratio of dietary sodium to potassium and blood pressure in a diverse sample of Hispanics living in the United States. METHODS: This analysis included 11,429 Hispanic/Latino participants of the prospective cohort Hispanic Community Health Study/Study of Latinos recruited between 2008 and 2011 in visit 1 who participated in a follow-up visit in 2014-2017. Dietary sodium and potassium intakes were averaged from 2 interviewer-administered 24-h diet recalls collected at visit 1. At both visits, blood pressure was measured 3 times in a seated position and averaged. We assessed the relationship between dietary sodium, potassium, and the sodium-to-potassium ratio with changes in systolic and diastolic blood pressure using survey-weighted multivariable-adjusted regression models. RESULTS: At visit 1, the mean age was 41 y, and the mean sodium intake was 3203 mg/d. Each 500 mg/d sodium increment in intake was associated with an increase in systolic blood pressure (ß: 0.35 [mmHg]; 95% confidence interval: 0.06, 0.63) and diastolic blood pressure (ß: 0.45 [mmHg]; 95% confidence interval: 0.08, 0.82). Dietary potassium and the molar ratio of dietary sodium to potassium were not associated with changes in systolic or diastolic blood pressure. CONCLUSIONS: Among a large sample of diverse United States Hispanic/Latino adults, higher sodium intake was associated with small increases in systolic blood pressure over 6 y. This research underscores the importance of dietary sodium reduction in maintaining lower blood pressure.

Economic and Psychosocial Impact of COVID-19 in the Hispanic Community Health Study/Study of Latinos.

Objectives: To examine the prevalence and correlates of economic hardship and psychosocial distress experienced during the initial phase of the coronavirus disease 2019 (COVID-19) pandemic in a large cohort of Hispanic/Latino adults. Methods: The Hispanic Community Health Study/Study of Latinos (HCHS/SOL), an ongoing multicenter study of Hispanic/Latino adults, collected information about COVID-19 illness and psychosocial and economic distress that occurred during the pandemic (N=11,283). We estimated the prevalence of these experiences during the initial phase of the pandemic (May 2020 to May 2021) and examined the prepandemic factors associated with pandemic-related economic hardship and emotional distress using multivariable log linear models with binomial distributions to estimate prevalence ratios. Results: Almost half of the households reported job losses and a third reported economic hardship during the first year of the pandemic. Pandemic-related household job losses and economic hardship were more pronounced among noncitizens who are likely to be undocumented. Pandemic-related economic hardship and psychosocial distress varied by age group and sex. Contrary to the economic hardship findings, noncitizens were less likely to report pandemic-related psychosocial distress. Prepandemic social resources were inversely related to psychosocial distress. Conclusions: The study findings underscore the economic vulnerability that the pandemic has brought to ethnic minoritized and immigrant populations in the United States, in particular noncitizens. The study also highlights the need to incorporate documentation status as a social determinant of health. Characterizing the initial economic and mental health impact of the pandemic is important for understanding the pandemic consequences on future health.

Evolving Science on Cardiovascular Disease Among Hispanic/Latino Adults: JACC International.

The landmark, multicenter HCHS/SOL (Hispanic Community Health Study/Study of Latinos) is the largest, most comprehensive, longitudinal community-based cohort study to date of diverse Hispanic/Latino persons in the United States. The HCHS/SOL aimed to address the dearth of comprehensive data on risk factors for cardiovascular disease (CVD) and other chronic diseases in this population and has expanded considerably in scope since its inception. This paper describes the aims/objectives and data collection of the HCHS/SOL and its ancillary studies to date and highlights the critical and sizable contributions made by the study to understanding the prevalence of and changes in CVD risk/protective factors and the burden of CVD and related chronic conditions among adults of diverse Hispanic/Latino backgrounds. The continued follow-up of this cohort will allow in-depth investigations on cardiovascular and pulmonary outcomes in this population, and data from the ongoing ancillary studies will facilitate generation of new hypotheses and study questions.

Doubled-Up Households, Self-Management Behaviors, Diabetes Preventive Care Services, and Hospital Use in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) 2015-2020.

OBJECTIVE: We investigated associations of living in a doubled-up household (i.e., adults living with adult children, other related adults, or other unrelated adults) with diabetes self-management behaviors, occurrence of diabetes preventive care services, and hospital use by Hispanic/Latino adults with diabetes. RESEARCH DESIGN AND METHODS: We analyzed data from the second clinical visit (2014-2017) through subsequent annual follow-up interviews completed through January 2020 of all participants with diabetes in the Hispanic Community Health Study/Study of Latinos. Multivariable regression was used to test associations between doubled-up status with diabetes self-management behaviors (i.e., checking blood glucose level, checking feet for sores), diabetes preventive care services done by a doctor (i.e., dilated-eye examination, feet checked, hemoglobin A1c measured, urine analysis for kidney function), and hospital use (i.e., emergency department [ED] visits and hospitalizations). RESULTS: Hispanic/Latino adults living doubled up were less likely to have their urine checked by a doctor for kidney disease compared with adults not in doubled-up households. Doubled-up status was not associated with diabetes self-management behaviors. Adults living doubled up in a household with other related adults had a 33% increased risk of ED visits compared with adults living doubled up in a household with adult children. CONCLUSIONS: Health care settings where Hispanic/Latino adults with diabetes receive trusted care should add housing characteristics such as doubled-up status to social-needs screening to identify residents in need of connecting with housing or social services and more targeted diabetes management services.

Subjective cognitive decline and objective cognition among diverse U.S. Hispanics/Latinos: Results from the Study of Latinos-Investigation of Neurocognitive Aging (SOL-INCA).

INTRODUCTION: Despite increased risk of cognitive decline in Hispanics/Latinos, research on early risk markers of Alzheimer's disease in this group is lacking. Subjective cognitive decline (SCD) may be an early risk marker of pathological aging. We investigated associations of SCD with objective cognition among a diverse sample of Hispanics/Latinos living in the United States. METHODS: SCD was measured with the Everyday Cognition Short Form (ECog-12) and cognitive performance with a standardized battery in 6125 adults aged ≥ 50 years without mild cognitive impairment or dementia (x̄age  = 63.2 years, 54.5% women). Regression models interrogated associations of SCD with objective global, memory, and executive function scores. RESULTS: Higher SCD was associated with lower objective global (B = -0.16, SE = 0.01), memory (B = -0.13, SE = 0.02), and executive (B = -0.13, SE = 0.02, p's < .001) function composite scores in fully adjusted models. DISCUSSION: Self-reported SCD, using the ECog-12, may be an indicator of concurrent objective cognition in diverse middle-aged and older community-dwelling Hispanics/Latinos.

Periodontal Disease and Incident CKD in US Hispanics/Latinos: The Hispanic Community Health Study/Study of Latinos.

RATIONALE & OBJECTIVE: Recent studies suggest that periodontal disease may be associated with incident chronic kidney disease (CKD). However, studies have focused on older populations, and US Hispanics/Latinos were not well represented. STUDY DESIGN: Observational cohort. SETTING & PARTICIPANTS: We analyzed data from the Hispanic Community Health Study/Study of Latinos who completed a baseline visit with a periodontal examination and a follow-up visit, and did not have CKD at baseline. PREDICTORS: Predictors included ≥30% of sites with clinical attachment loss ≥3 mm, ≥30% of sites with probing depth ≥4 mm, percentage of sites with bleeding on probing, and absence of functional dentition (<21 permanent teeth present). OUTCOMES: Outcomes were incident low estimated glomerular filtration rate (eGFR) (eGFR <60 mL/min/1.73 m2 and decline in eGFR ≥1 mL/min/year); incident albuminuria (urine albumin:creatinine ratio [ACR] ≥30 mg/g); and change in eGFR and ACR. ANALYTIC APPROACH: Poisson and linear regression. RESULTS: For the sample (n = 7.732), baseline mean age was 41.5 years, 45.2% were male, 11.7% had ≥30% of sites with clinical attachment loss ≥3 mm, 5.1% had ≥30% of sites with probing depth ≥4 mm, 30.7% had ≥50% of sites with bleeding on probing, and 16.2% had absent functional dentition. During a median follow-up of 5.9 years, 149 patients developed low eGFR and 415 patients developed albuminuria. On multivariable analysis, presence versus absence of ≥30% of sites with probing depth ≥4 mm and absence of functional dentition were each associated with increased risk for incident low eGFR (incident density ratio, 2.31; 95% CI, 1.14-4.65 and 1.65, 95% CI, 1.01-2.70, respectively). None of the other predictors were associated with outcomes. LIMITATIONS: Only a single kidney function follow-up measure. CONCLUSIONS: In this cohort of US Hispanics/Latinos, we found that select measures of periodontal disease were associated with incident low eGFR. Future work is needed to assess whether the treatment of periodontal disease may prevent CKD.

Retaining Hispanics: Lessons From the Hispanic Community Health Study/Study of Latinos.

We aimed to examine the retention of Hispanics/Latinos participating in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), a prospective cohort study of 16,415 adults in 4 US cities who were enrolled between 2008 and 2011. We summarized retention strategies and examined contact, response, and participation rates over 5 years of annual follow-up interviews. We then evaluated motivations for participation and satisfaction with retention efforts among participants who completed a second in-person interview approximately 6 years after their baseline interview. Finally, we conducted logistic regression analyses estimating associations of demographic, health, and interview characteristics at study visit 1 (baseline) with participation, high motivation, and high satisfaction at visit 2. Across 5 years, the HCHS/SOL maintained contact, response, and participation rates over 80%. The most difficult Hispanic/Latino populations to retain included young, single, US-born males with less than a high school education. At visit 2, we found high rates of motivation and satisfaction. HCHS/SOL participants primarily sought to help their community and learn more about their health. High rates of retention of Hispanics/Latinos can be facilitated through the employment of bilingual/bicultural staff and the development of culturally tailored retention materials.

Cultural factors and oral health-related quality of life among dentate adults: Hispanic community health study/study of Latinos.

Objective: Research on the relationships between acculturation, ethnic identity, and oral health-related quality of life (OHRQOL) among the U.S. Hispanic/Latino population is sparse. The aim of this study is to examine the association between acculturation, ethnic identity, and OHRQOL among 13,172 adults in the 2008-2011 Hispanic Community Health Study/Study of Latinos (HCHS/SOL).Design: Participants self-reported their acculturation (immigrant generation, birthplace, residence in the U.S., language, and social acculturation), ethnic identity (sense of belonging and pride), and four OHRQOL measures. Key socio-demographic, behavioral, and oral health outcomes were tested as potential confounders.Results: Overall, 57% of individuals experienced poor OHRQOL in at least one of the domains examined. In multivariable analyses, some elements of higher acculturation were associated with greater food restriction and difficulty doing usual jobs/attending school, but not associated with pain or difficulty chewing, tasting, or swallowing. While sense of belonging to one's ethnic group was not associated with poor OHRQOL, low sense of pride was associated with food restriction. Socio-behavioral characteristics were significant effect modifiers.Conclusion: This study contributes to the understanding of the role of Hispanic/Latino's cultural factors in OHRQOL perception and can inform targeted strategies to improve OHRQOL in this diverse population.

A research framework for cognitive aging and Alzheimer's disease among diverse US Latinos: Design and implementation of the Hispanic Community Health Study/Study of Latinos-Investigation of Neurocognitive Aging (SOL-INCA).

Hispanics/Latinos are the largest ethnic/racial group in the United States and at high risk for Alzheimer's disease and related dementia (ADRD). Yet, ADRD among diverse Latinos is poorly understood and disparately understudied or unstudied compared to other ethnic/racial groups that leave the nation ill-prepared for major demographic shifts that lay ahead in coming decades. The primary purpose of this Perspectives article was to provide a new research framework for advancing Latino ADRD knowledge, encompassing the unique sociocultural, cardiometabolic, and genomic aspects of Latino health, aging, and ADRD. In addition, we describe some of the research challenges to progress in Latino ADRD research. Finally, we present the Study of Latinos - Investigation of Neurocognitive Aging (SOL-INCA) as an example of implementing this new framework for advancing Latino ADRD research.

Prevalence and correlates of mild cognitive impairment among diverse Hispanics/Latinos: Study of Latinos-Investigation of Neurocognitive Aging results.

INTRODUCTION: We estimated the prevalence and correlates of mild cognitive impairment (MCI) among middle-aged and older diverse Hispanics/Latinos. METHODS: Middle-aged and older diverse Hispanics/Latinos enrolled (n = 6377; 50-86 years) in this multisite prospective cohort study were evaluated for MCI using the National Institute on Aging-Alzheimer's Association diagnostic criteria. RESULTS: The overall MCI prevalence was 9.8%, which varied between Hispanic/Latino groups. Older age, high cardiovascular disease (CVD) risk, and elevated depressive symptoms were significant correlates of MCI prevalence. Apolipoprotein E4 (APOE) and APOE2 were not significantly associated with MCI. DISCUSSION: MCI prevalence varied among Hispanic/Latino backgrounds, but not as widely as reported in the previous studies. CVD risk and depressive symptoms were associated with increased MCI, whereas APOE4 was not, suggesting alternative etiologies for MCI among diverse Hispanics/Latinos. Our findings suggest that mitigating CVD risk factors may offer important pathways to understanding and reducing MCI and possibly dementia among diverse Hispanics/Latinos.

Alcohol use, acculturation and socioeconomic status among Hispanic/Latino men and women: The Hispanic Community Health Study/Study of Latinos.

The objective of this study was to examine the prevalence and patterns of alcohol use among U.S. Hispanic/Latino adults of diverse backgrounds. The population-based Hispanic Community Health Study/ Study of Latinos (HCHS/SOL) enrolled a cohort of Hispanic/Latino adults (N = 16,415) ages 18-74 years at time of recruitment, from four US metropolitan areas between 2008-11. Drinking patterns and socio-demographics questionnaires were administered as part of the baseline examination. The relationship between age, sex, socio-demographics, acculturation, current alcohol use, and alcohol risk disorder, defined by the National Institute on Alcohol Abuse and Alcoholism (NIAAA) [no risk (i.e., never drinker), low risk (i.e., women<7 drinks/week; men<14 drinks/week), and at-risk (i.e., women>7 drinks/week; men>14 drinks/week)] were assessed in unadjusted and adjusted multinomial logistic regression analyses. Men reported a higher prevalence than women of at-risk drinking. For women, increased odds of at-risk alcohol use was associated with: a younger age, greater education, full-time employment, and acculturation after adjustment. For men, having a lower income (vs. higher income) or a higher income (vs. not reported) and being employed fulltime (vs. retired) was associated with at-risk alcohol use. For both men and women, there were variations in odds of at-risk drinking across Hispanic/Latino heritage backgrounds, after adjustment. Exact values, odds ratios and p-values are reported within the text. Common factors across sex associated with at-risk drinking included being of Mexican background and being employed full-time. Intervention strategies should consider diversity within the Hispanic/Latino community when designing alcohol abuse prevention programs.

Unfair Treatment and Periodontitis Among Adults in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL).

This study investigates how perceived unfair treatment, towards self and observed towards others due to ethnicity, is associated with periodontitis among diverse Hispanic/Latino adults, accounting for sociodemographic, health behavior, and acculturation factors. Baseline (2008-2011) dental and survey data from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), a multicenter epidemiologic study, were analyzed (N = 12,750). Crude and adjusted prevalence ratios and confidence limits were estimated. Half (49%) reported never being treated unfairly, while 41% reported they were sometimes, and 10% reported it often/always. One third (32%) never saw others treated unfairly, while 42% reported it sometimes, and 26% reported it often/always. In the final fully adjusted model, the prevalence of periodontitis was higher among adults who were as follows: non-Dominican, older, male, had a past year dental visit, current and former smokers, and among those who observed unfair treatment towards others. Lower prevalence was associated with higher income, higher educational attainment, less than full-time employment, reporting experiencing unfair treatment, higher acculturation scores, and having health insurance. Perceived unfair treatment towards self was negatively associated with periodontitis prevalence, while observed unfair treatment towards others was positively associated with the outcome among diverse Hispanics/Latinos. The associations between unfair treatment and periodontitis warrant further exploration.

Validation of the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being-Expanded (FACIT-Sp-Ex) Across English and Spanish-Speaking Hispanics/Latinos: Results From the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study.

The validity of the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being (FACIT-Sp) has been examined in primarily non-Hispanics/Latinos with chronic illness. This study assessed the psychometric properties of the non-illness, expanded FACIT-Sp (FACIT-Sp-Ex) in 5,163 U.S. Hispanic/Latino adults. Measures were interviewer-administered in English or Spanish. Confirmatory factor analyses indicated four factors: Meaning, Peace, Faith, and Relational. The scale demonstrated measurement invariance across English and Spanish. Subscales displayed adequate internal and test-retest reliability. Scores were positively associated with Duke Religion Index (DUREL) subscales. When all subscales were entered in a single model, Meaning and Peace were inversely associated with depressive symptoms and positively associated with HRQOL. Faith was positively associated with depressive symptoms and inversely associated with HRQOL. Relational was not associated with any outcome. FACIT-Sp-Ex subscales were generally more strongly associated than DUREL subscales with well-being. The FACIT-Sp-Ex appears to be a valid measure of spiritual well-being in U.S. Hispanics/Latinos.

Analytical and biological variability in biomarker measurement in the Hispanic Community Health Study/Study of Latinos.

BACKGROUND: Biomarker variability, which includes within-individual variability (CVI), between-individual variability (CVG) and methodological variability (CVP+A) is an important determinant of our ability to detect biomarker-disease associations. Estimates of CVI and CVG may be population specific and little data exists on biomarker variability in diverse Hispanic populations. Hence, we evaluated all 3 components of biomarker variability in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) using repeat blood collections (n=58) and duplicate blood measurements (n=761-929 depending on the biomarker). METHODS: We estimated the index of individuality (II) ((CVI+CVP+A)/CVG) for 41 analytes and evaluated differences in the II across sexes and age groups. RESULTS: Biomarkers such as fasting glucose, triglycerides and ferritin had substantially higher inter-individual variability and lower II in HCHS/SOL as compared to the published literature. We also found significant sex-specific differences in the II for neutrophil count, platelet count, hemoglobin, % eosinophils and fasting glucose. The II for fasting insulin, post oral glucose tolerance test glucose and cystatin C was significantly higher among the 18-44y age group as compared to the 45+y age group. CONCLUSIONS: The implications of these findings for determining biomarker-disease associations in Hispanic populations need to be evaluated in future studies.

Association of Impaired Glucose Regulation and Insulin Resistance With Cardiac Structure and Function: Results From ECHO-SOL (Echocardiographic Study of Latinos).

BACKGROUND: We examined the relationship between glucose homeostasis and comprehensive measures of cardiac structure and function among a representative sample of US Hispanics. METHODS AND RESULTS: ECHO-SOL (Echocardiographic Study of Latinos), an echocardiographic ancillary study of the HCHS/SOL (Hispanic Community Health Study/Study of Latinos), enrolled 1818 Hispanic/Latino men (43%) and women (57%) aged ≥45 years (mean=56). Glucose intolerance was defined as follows: (1) prediabetes: hemoglobin (HbA1c) ≥5.7 and <6.5% and (2) diabetes mellitus: fasting plasma glucose ≥126 mg/dL, 2-hour postload glucose ≥200 mg/dL, HbA1c ≥6.5%, or hypoglycemic agent use. Uncontrolled diabetes mellitus was defined as HbA1c ≥7.0%. Insulin resistance was defined using the homeostatic model assessment for insulin resistance. Echocardiography examinations assessed left ventricular structure and systolic/diastolic function. Multivariable linear and logistic regression models were used. Prediabetes prevalence was 42%, and diabetes mellitus prevalence was 28% (47% uncontrolled). Glucose intolerance was associated with increased left ventricular posterior wall and interventricular septal and relative wall thicknesses (all P<0.05), reduced ejection fraction (P<0.01), reduced stroke and end-diastolic volumes (both P<0.001), decreased peak E' velocity (lateral and septal P<0.001), and increased E/E' ratio (lateral and septal P<0.01). The odds ratios (95% confidence intervals) for diastolic dysfunction among individuals with prediabetes and diabetes mellitus (versus diabetes mellitus free) were 1.36 (0.96-1.9) and 1.90 (1.3-2.8), respectively(P=0.006). Results were consistent for uncontrolled diabetes mellitus versus diabetes mellitus. Homeostatic model assessment for insulin resistance was associated with increased E/E' (P<0.001), and greater relative wall thickness and septal thickness (both P<0.05); lower stroke volume (P<0.0001); and lower peak lateral and septal E' velocities (both P<0.01). CONCLUSIONS: Glucose intolerance and insulin resistance are associated with unfavorable cardiac structure and function, particularly worsened measures of diastolic function, even before the development of diabetes mellitus.

Burden of Systolic and Diastolic Left Ventricular Dysfunction Among Hispanics in the United States: Insights From the Echocardiographic Study of Latinos.

BACKGROUND: Population-based estimates of cardiac dysfunction and clinical heart failure (HF) remain undefined among Hispanics/Latino adults. METHODS AND RESULTS: Participants of Hispanic/Latino origin across the United States aged 45 to 74 years were enrolled into the Echocardiographic Study of Latinos (ECHO-SOL) and underwent a comprehensive echocardiography examination to define left ventricular systolic dysfunction (LVSD) and left ventricular diastolic dysfunction (LVDD). Clinical HF was defined according to self-report, and those with cardiac dysfunction but without clinical HF were characterized as having subclinical or unrecognized cardiac dysfunction. Of 1818 ECHO-SOL participants (mean age 56.4 years; 42.6% male), 49.7% had LVSD or LVDD or both. LVSD prevalence was 3.6%, whereas LVDD was detected in 50.3%. Participants with LVSD were more likely to be males and current smokers (all P<0.05). Female sex, hypertension, diabetes mellitus, higher body mass index, and renal dysfunction were more common among those with LVDD (all P<0.05). In age-sex adjusted models, individuals of Central American and Cuban backgrounds were almost 2-fold more likely to have LVDD compared with those of Mexican backgrounds. Prevalence of clinical HF with LVSD (HF with reduced EF) was 7.3%; prevalence of clinical HF with LVDD (HF with preserved EF) was 3.6%. 96.1% of the cardiac dysfunction seen was subclinical or unrecognized. Compared with those with clinical cardiac dysfunction, prevalent coronary heart disease was the only factor independently associated with subclinical or unrecognized cardiac dysfunction (odds ratio: 0.1; 95% confidence interval: 0.1-0.4). CONCLUSIONS: Among Hispanics/Latinos, most cardiac dysfunction is subclinical or unrecognized, with a high prevalence of diastolic dysfunction. This identifies a high-risk population for the development of clinical HF.

Factors Associated With Ocular Health Care Utilization Among Hispanics/Latinos: Results From an Ancillary Study to the Hispanic Community Health Study/Study of Latinos (HCHS/SOL).

IMPORTANCE: Regular ocular care is critical to early detection and prevention of eye disease and associated morbidity and mortality; however, there have been relatively few studies of ocular health care utilization among Hispanics/Latinos of diverse backgrounds. OBJECTIVE: To examine factors associated with ocular health care utilization among Cuban, Central American, and South American Hispanics/Latinos in a cohort study. DESIGN, SETTING, AND PARTICIPANTS: An ancillary study to the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) evaluating ocular health, knowledge, risk factors, and health care use was conducted with 1235 HCHS/SOL participants (aged ≥40 years) at the Miami, Florida, study site. Data were collected from October 17, 2011, to September 30, 2013, and analyses were conducted from May 28, 2014, to March 18, 2015. Descriptive and multivariable logistic regression analyses were performed for 3 ocular health care outcomes. Regression models were built sequentially with variables conceptually grouped according to Andersen's Behavioral Model of Health Services Use. MAIN OUTCOMES AND MEASURES: Ever having an eye examination, having an eye examination performed within the past 2 years, and difficulty obtaining needed eye care in the past year. RESULTS: Of the 1235 participants, 478 were men and 757 were women, and they had a mean (SD) age of 53.6 (8.1) years. Those who never had insurance were less likely to have had an eye examination (with data reported as odds ratios [95% CIs]) ever, 0.19 (0.07-0.53) and in the past 2 years, 0.22 (0.15-0.33) and were more likely to have had difficulty obtaining needed eye care in the past year (3.72 [1.75-7.93]). Those with less than excellent or good self-rated eyesight were less likely to ever have had an eye examination (0.26 [0.12-0.56]) and more likely to have had difficulty obtaining care (3.00 [1.48-6.11]). Men were less likely to ever have had an eye examination (0.31 [0.18-0.53]). Older (55-64 years) Hispanics/Latinos (3.04 [1.47-6.31]) and those with a high school degree or general educational development certification (2.06 [1.02-4.13]) or higher levels of education (4.20 [2.12-8.30]) were more likely to ever have had an eye examination. Finally, those living in the United States for more than 15 years (0.42 [0.21-0.82]) were less likely to have had difficulty obtaining care. CONCLUSIONS AND RELEVANCE: Our findings suggest that increasing insurance coverage, decreasing the costs of care, and increasing the availability of care for Hispanics/Latinos with poor self-rated eyesight are relevant issues to address to improve ocular health care use among Hispanics/Latinos of diverse backgrounds.

The distribution of hepatitis B virus exposure and infection in a population-based sample of U.S. Hispanic adults.

UNLABELLED: Little is known regarding the prevalence and distribution of hepatitis B virus (HBV) infection in U.S. Hispanics/Latinos. We sought to determine the prevalence of HBV exposure (serum HBV core antibody; anti-HBc), active HBV infection (serum HBV surface antigen; HBsAg), and vaccine-induced HBV immunity (antibody against HBV surface antigen; anti-HBs) in U.S. Hispanics/Latinos and consider how these data inform clinical screening recommendations. Our analysis included 11,999 women and men of the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), a population-based, household survey in four urban communities (Bronx, NY; Miami, FL; Chicago, IL; and San Diego, CA) of U.S. civilian, noninstitutionalized self-identifying Hispanic/Latino adults ages 18-74. Vaccine-induced immunity was defined as detection of anti-HBs, but not anti-HBc. However, if anti-HBc were present, it was considered evidence of exposure to HBV, with detection of HBsAg used to distinguish those with active HBV infection. Mean age was 45.7 years, and 7,153 were women. Vaccine-induced immunity was greatest among those ages 18-29 years (60.2% in women, 54% in men) and decreased with increasing age, regardless of country of birth. The prevalence of active HBV infection was 0.29% (95% confidence interval: 0.19-0.43), but varied by country of birth. Those born in the Dominican Republic had the highest prevalence of HBV exposure (20.3% in women, 29.7% in men) and active HBV infection (0.95%). CONCLUSIONS: The overall age-standardized prevalence of active HBV infection in Hispanic/Latino adults (0.29%) was no different from the general U.S. population estimate (0.27%) and did not exceed 2%, regardless of country of birth. These data do not support targeting HBV screening to US Hispanic/Latino adults based upon background.

Prevalence of suspected nonalcoholic fatty liver disease in Hispanic/Latino individuals differs by heritage.

BACKGROUND & AIMS: Nonalcoholic fatty liver disease (NAFLD) was shown to disproportionally affect Hispanic persons. We examined the prevalence of suspected NAFLD in Hispanic/Latino persons with diverse backgrounds. METHODS: We studied the prevalence of suspected NAFLD among 12,133 persons included in the Hispanic Community Health Study/Study of Latinos. We collected data on levels of aminotransferase, metabolic syndrome (defined by National Cholesterol Education Program-Adult Treatment Panel III guidelines), demographics, and health behaviors. Suspected NAFLD was defined on the basis of increased level of aminotransferase in the absence of serologic evidence for common causes of liver disease or excessive alcohol consumption. In multivariate analyses, data were adjusted for metabolic syndrome, age, acculturation, diet, physical activity, sleep, and levels of education and income. RESULTS: In multivariate analysis, compared with persons of Mexican heritage, persons of Cuban (odds ratio [OR], 0.69; 95% confidence interval [CI], 0.57-0.85), Puerto Rican (OR, 0.67; 95% CI, 0.52-0.87), and Dominican backgrounds (OR, 0.71; 95% CI, 0.54-0.93) had lower rates of suspected NAFLD. Persons of Central American and South American heritage had a similar prevalence of suspected NAFLD compared with persons of Mexican heritage. NAFLD was less common in women than in men (OR, 0.49; 95% CI, 0.40-0.60). Suspected NAFLD associated with metabolic syndrome and all 5 of its components. CONCLUSIONS: On the basis of an analysis of a large database of health in Latino populations, we found the prevalence of suspected NAFLD among Hispanic/Latino individuals to vary by region of heritage.
