Demographic and sociocultural risk factors for adulthood weight gain in Hispanic/Latinos: results from the Hispanic Community Health Study / Study of Latinos (HCHS/SOL).

BACKGROUND: United States (US) Hispanic/Latinos experience a disproportionate burden of obesity, which may in part be related to demographic or sociocultural factors, including acculturation to an US diet or inactive lifestyle. Therefore, we sought to describe the association between adulthood weight histories and demographic and sociocultural factors in a large diverse community-based cohort of US Hispanic/Latinos. METHODS: We estimated the effect of several factors on weight gain across adulthood, using multivariable linear mixed models to leverage 38,759 self-reported current body weights and weight histories recalled for 21, 45 and 65 years of age, from 15,203 adults at least 21 years of age at the baseline visit of the Hispanic Community Health Study/Study of Latinos (2008-2011). RESULTS: The average rate of weight gain was nearly 10 kg per decade in early adulthood, but slowed to < 5 kg a decade among individuals 60+ years of age. Birth cohort, gender, nativity or age at immigration, Hispanic/Latino background, and study site each significantly modified the form of the predicted adulthood weight trajectory. Among immigrants, weight gain during the 5 years post-migration was on average 0.88 kg (95% CI: 0.04, 1.72) greater than the weight gain during the 5 years prior. The rate of weight gain appeared to slow after 15 years post-migration. CONCLUSIONS: Using self-reported and weight history data in a diverse sample of US Hispanic/Latinos, we revealed that both demographic and sociocultural factors were associated with the patterning of adulthood weight gain in this sample. Given the steep rate of weight gain in this population and the fact that many Hispanic/Latinos living in the US immigrated as adults, efforts to promote weight maintenance across the life course, including after immigration, should be a top priority for promoting Hispanic/Latino health and addressing US health disparities more broadly.

Hemiarthroplasty vs Total Hip Arthroplasty for Femoral Neck Fractures: 2010-2017 Trends in Complication Rates.

BACKGROUND: Optimal treatment of femoral neck fractures (FNFs) remains debated. Recent data suggest that total hip arthroplasty (THA) confers improved functional outcomes compared to hemiarthroplasty (HA) in active patients. However, temporal trends in complication rates between these treatments lack study. METHODS: The National Surgical Quality Improvement Program database was retrospectively queried to compare differences between HA and THA over time (2010-2012, 2013-2015, and 2016-2017) in blood transfusions, operation time, major complications, minor complications, and 30-day readmission, among FNF patients aged ≥50 years. Analyses adjusted for age, gender, anesthesia type, smoking, body mass index, hypertension, bleeding disorder, steroid use, and American Society of Anesthesiologists classification. RESULTS: In total, 16,213 patients were identified. THA was associated with higher transfusion rates in 2010-2012 (mean = 0.34 vs 0.28, P = .001) and 2013-2015 (mean = 0.21 vs 0.19, P = .002), but not in 2016-2017 (mean = 0.13 vs 0.14, P = .146). Operation time was significantly higher for THA across all periods (P's < .001), but declined over time. In recent years, THA was associated with less major (2016-2017: 5.4% vs 10.2%, P = .02; 2013-2015: 5.3% vs 10.3%, P < .001) and minor (2016-2017: 6.2% vs 9.8%, P = .02; 2013-2015: 7.2% vs 12.4%, P < .001) complications compared to 2010-2012 (major: 7.2% vs 10.6%, P = .87; minor: 12.6% vs 10.1%, P = .89). No differences in 30-day readmission were noted. CONCLUSION: THA was associated with less major and minor complications in recent time periods compared to HA for the treatment of FNF, controlling for comorbidities. THA trends in transfusions and operation duration have improved over time compared to HA.

Childhood Trauma and Adult Risk Factors and Disease in Hispanics/Latinos in the US: Results From the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) Sociocultural Ancillary Study.

OBJECTIVE: Adverse childhood experiences (ACEs) are implicated in diseases of adulthood. We report the prevalence of ACEs in Hispanics/Latinos in the US and their association with major risk factors and diseases in adulthood. METHODS: Data from the Sociocultural Ancillary Study of the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) were used. The Sociocultural Ancillary Study of the Hispanic Community Health Study/Study of Latinos is an epidemiological study conducted in four urban communities in the US: Bronx, Chicago, Miami, and San Diego. The analytic sample comprised 5117 participants, ages 18 to 74 at baseline. Linear and logistic models, adjusted for sociodemographic factors, were used to examine associations of ACEs and risk factors (depressive symptoms, obesity, smoking, and alcohol use) and chronic disease (coronary heart disease, stroke, diabetes, asthma, chronic obstructive pulmonary disease, and cancer); the latter were also adjusted for risk factors. RESULTS: Most participants (77.2%) experienced at least one ACE, and 28.7% experienced four or more. Adverse childhood experiences were common among all ancestry groups, with variability among them. Prevalence of four or more ACEs was higher among women than men (31.2% and 25.8%, respectively). Adverse childhood experiences were associated with depressive symptoms, body mass index, smoking, alcohol use, cancer, coronary heart disease, and chronic obstructive pulmonary disease, but not asthma, diabetes, or stroke. Associations were not moderated by social support. CONCLUSIONS: Adverse childhood experiences are prevalent among US Hispanics/Latinos and are involved in disease in adulthood. The apparent higher prevalence of ACEs in US Hispanics/Latinos did not correspond with stronger associations with disease. Further studies are needed to identify factors that may moderate the associations of ACE with adult disease.

Family Environment and the Metabolic Syndrome: Results from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) Sociocultural Ancillary Study (SCAS).

BACKGROUND: Metabolic syndrome (MetS) is a risk factor for cardiovascular disease. Very limited work has evaluated associations of sociocultural processes with prevalence of the MetS. PURPOSE: The purpose of the present study was to evaluate associations between family environment (cohesion/conflict) and the MetS, in a multi-site sample of US Hispanics/Latinos. METHODS: A total of 3278 participants from the Hispanic Community Health Study/Study of Latinos underwent a clinical exam and completed psychosocial measures including family environment (cohesion and conflict) as part of the Sociocultural Ancillary Study. RESULTS: The association between family environment and the MetS was moderated by sex. Among all women, higher family conflict was associated with MetS prevalence. Results by ancestry group showed that only among Cuban women, higher conflict was associated with the MetS, whereas only among Dominican men, greater cohesion was associated with the MetS. CONCLUSIONS: The family context may be a sociocultural protective or risk factor among Hispanics/Latinos in terms of MetS risk, but these associations may vary by sex and Hispanic background.

Cigarette Smoking and Depressive Symptoms Among Hispanic/Latino Adults: Results From the Hispanic Community Health Study/Study of Latinos (HCHS/SOL).

INTRODUCTION: In the present study, we investigated associations among cigarette smoking, smoking cessation treatment, and depressive symptoms in Hispanic/Latino adults. METHODS: The multisite prospective population-based Hispanic Community Health Study/Study of Latinos (HCHS/SOL) enrolled a cohort of Hispanic/Latino adults (aged 18-74) from diverse backgrounds (n = 16,412) in 4U.S. communities (Chicago, San Diego, Miami, and Bronx). Households were selected using a stratified 2-stage probability sampling design and door-to-door recruitment, and sampling weights calibrated to the 2010U.S. Population Census. Hispanic/Latino individuals of Dominican, Central American, South American, Cuban, Mexican, and Puerto Rican background were considered. Cigarette smoking, smoking cessation treatment, and depressive symptoms were measured by self-report. RESULTS: Results indicated that current smokers had greater odds for significant depressive symptoms (CES-D score ≥ 10) than never smokers in all Hispanic background groups [odds ratio (OR) > 1.5]. Depressed persons were not more likely to receive prescribed smoking cessation medications from a doctor (OR = 1.43, 95% CI = 0.98-2.08), take over-the-counter medications (OR = 1.11, 95% CI = 0.75-1.66), or receive psychotherapy (OR = 1.02, 95% CI = 0.57-1.85). CONCLUSIONS: In conclusion, these findings suggest that the positive association between smoking status and depressive symptoms is present in all examined Hispanic/Latino background groups.

Mental Health and Exposure to the United States: Key Correlates from the Hispanic Community Health Study of Latinos.

We examined the association between exposure to the U.S. and symptoms of poor mental health among adult Hispanic/Latinos (N = 15,004) overall and by Hispanic/Latino background. Using data from the Hispanic Community Health Study of Latinos (HCHS/SOL), we estimated logistic regressions to model the risk of moderate to severe symptoms of psychological distress, depression, and anxiety as a function of years in the U.S. and six key psychosocial risk and protective factors. In unadjusted models, increased time in the U.S. was associated with higher risk of poor mental health. After adjustment for just three key factors--perceived discrimination, perceived U.S. social standing, and the size of close social networks--differences in the odds of poor mental health by years in the U.S became insignificant for Hispanics/Latinos overall. However, analyses by Hispanic/Latino background revealed different patterns of association with exposure to the U.S. that could not be fully explained.

Depressive symptoms and carotid intima-media thickness in South American Hispanics: results from the PREVENCION study.

This study aimed to: (1) examine the relationship between depressive symptoms and subclinical atherosclerosis, measured by carotid intima-media thickness (IMT); and, (2) Determine the moderating effect of gender in this relationship among South American Hispanics. We studied 496 adults enrolled in the population-based PREVENCION study. Carotid IMT was measured with high-resolution ultrasonography. Depressive symptoms were assessed using the Hospital Anxiety and Depression Scale. Mean carotid IMT was 0.66 mm. (SD = 0.17) and mean depression score was 5.6 (SD = 3.5). Depressive symptoms were not associated with carotid IMT (ß = 0.04, p = 0.222) in multivariate analyses. A significant moderating effect of gender was found (ß for interaction = 0.10, p = 0.030), resulting from a significant association between depressive symptoms and carotid IMT in men but not women. Depressive symptoms were associated with subclinical atherosclerosis in South American Hispanic men but not women after controlling for demographic characteristics and traditional cardiovascular risk factors.

Digital Fluoroscopic Navigation for Limb Length Restoration During Anterior Total Hip Arthroplasty.

Background: Restoration of limb length is important in total hip arthroplasty. Clinical evaluation and preoperative templating establish the intended lengthening. The purpose of this study was to assess whether digital fluoroscopic navigation (DF) improved the accuracy of planned lengthening in direct anterior approach total hip arthroplasty (DAA-THA). Methods: Planned lengthening measurements on 100 consecutive unilateral DAA-THA patients, along with patient characteristics, were prospectively collected by 2 surgeons. One surgeon utilized DF to achieve intended length (n = 50), while the other utilized unaided standard fluoroscopy (SF; n = 50). A third surgeon blinded to the procedures assessed actual limb length using an ipsilateral overlay technique on the 6-week postoperative radiograph. The difference between the mean planned and actual limb lengthening stratified by DF and SF was assessed using bivariate and multivariate statistics. Results: The mean (standard deviation) planned lengthening in DF and SF groups was 3.96 (2.1) and 3.47 (2.2) mm, respectively. The mean (standard deviation) actual lengthening in DF and SF groups was 3.11 (4.0) and 0.68 (4.6) mm, respectively. After accounting for age, sex, body mass index, laterality, and the Bone Index, multivariate regression results showed that the average difference between planned and actual limb lengthening in the DF group was significantly lower than that in the SF group (ß = -1.92; 95% confidence interval: -3.51, -0.33; P < .02). A greater percentage of patients in the DF group (66% vs 40%) were within 3 mm of the intended plan (P < .01). Conclusions: Fluoroscopy helps achieve the intended surgical lengthening in DAA-THA. The use of DF resulted in more accurate execution of lengthening.

Unicompartmental Knee Arthroplasty vs Total Knee Arthroplasty: A Risk-adjusted Comparison of 30-day Outcomes Using National Data From 2014 to 2018.

Background: When clinically indicated, the choice of performing a total knee arthroplasty (TKA) vs a unicompartmental knee arthroplasty (UKA) is dictated by patient and surgeon preferences. Increased understanding of surgical morbidity may enhance this shared decision-making process. This study compared 30-day risk-adjusted outcomes in TKA vs UKA using a national database. Methods: We analyzed data from the National Safety and Quality Improvement Program database, for patients who received TKA or UKA between 2014-2018. The main outcomes were blood transfusion, operation time, length of stay, major complication, minor complication, unplanned reoperation, and readmission. Comparisons of odds of the outcomes of interest between TKA and UKA patients were analyzed using multivariate regression models accounting for confounders. Results: We identified 274,411 eligible patients, of whom 265,519 (96.7%) underwent TKA, while 8892 (3.3%) underwent UKA. Risk-adjusted models that compared perioperative and postoperative outcomes of TKA and UKA showed that the odds of complications such as blood transfusion (adjusted odds ratio [aOR], 19.74; 95% confidence interval [CI]: 8.19-47.60), major (aOR, 1.87; 95% CI: 1.27-2.77) and minor complications (aOR, 1.43; 95% CI: 1.14-1.79), and readmission (aOR, 1.41; 95% CI: 1.16-1.72) were significantly higher among patients who received TKA than among those who received UKA. In addition, operation time (aOR, 7.72; 95% CI: 6.72-8.72) and hospital length of stay (aOR, 1.11; 95% CI: 1.05-1.17) were also higher among the TKA recipients compared to those who received UKA. Conclusions: UKA is associated with lower rates of adverse perioperative outcomes compared to TKA. Clinical indications and surgical morbidity should be considered in the shared-decision process.

Risk factor control across the spectrum of cardiovascular risk: Findings from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL).

BACKGROUND: Presence of cardiovascular disease (CVD) risk factors (RFs) should prompt patients and their providers to work aggressively towards controlling those that are modifiable. The extent to which a greater CVD RF burden is related to CVD RF control in a contemporary and diverse Hispanic/Latino population is not well-understood. METHODS: Using multicenter community-based data from the Hispanic Community Health Study/Study of Latinos, we assessed the self-reported prevalence of hypertension, hypercholesterolemia, diabetes, and prevalent CVD (ischemic heart disease or stroke). We used contemporaneous guidelines to define RF control. Multivariable logistic regression for complex survey sampling was used to examine whether having more CVD RFs was associated with CVD RF control (adjusting for age, sex, Hispanic background group, education, and health insurance). RESULTS: Our sample included 8521 participants with at least one CVD RF or prevalent CVD. The mean age in HCHS/SOL target population was 49 (SE 0.3) years and 56% were women. Frequency of one, two, or three self-reported CVD RFs was 57%, 26%, 8%, respectively, and overall 9% of participants had prevalent CVD. After adjusting for sociodemographic factors, compared to those reporting one CVD RF, individuals with three CVD RFs were the least likely to have blood pressure, cholesterol, and glucose optimally controlled (odds ratio [OR]: 0.56; 95% confidence interval [CI]: 0.40-0.80). However, those with prevalent CVD were more likely to have all three risk factors controlled, (OR: 1.43; 95% CI: 1.01-2.01). CONCLUSION: Hispanic/Latino adults with three major CVD RFs represent a group with poor overall CVD RF control. Secondary CVD prevention fares better. The potential contributors to inadequate CVD RF control in this highly vulnerable group warrants further investigation.

Loneliness, Cardiovascular Disease, and Diabetes Prevalence in the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study.

The relationship between loneliness and both cardiovascular disease (CVD) and diabetes mellitus (DM) has been understudied in U.S. Hispanics, a group at high risk for DM. We examined whether loneliness was associated with CVD and DM, and whether age, sex, marital status, and years in U.S moderated these associations. Participants were 5,313 adults (M (SD) age = 42.39 (15.01)) enrolled in the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study. Loneliness was assessed via the 3-item Revised UCLA Loneliness Scale. Level of reported loneliness was low. Loneliness was significantly associated with CVD: OR 1.10 (CI 1.01-1.20) and DM: OR 1.08 (CI 1.00-1.16) after adjusting for depression, demographics, body mass index, and smoking status. Age, sex, marital status, and years in U.S. did not moderate associations. Given that increased loneliness is associated with higher cardiometabolic disease prevalence beyond depressive symptoms, regardless of age, sex, marital status, or years in the U.S., Hispanic adults experiencing high levels of loneliness may be a subgroup at particularly elevated risk for CVD and DM.

Resiliency in the face of disadvantage: do Hispanic cultural characteristics protect health outcomes?

Hispanics living in the United States may face substantial adversity, given stresses of immigration and acculturation, low incomes, poor educational and occupational opportunities, inadequate access to health care, and exposure to discrimination. Despite these disadvantages, the Hispanic population often shows equal or better health outcomes when compared to non-Hispanic Whites, a trend that has puzzled researchers and has been referred to as the "Hispanic Paradox." Hispanics with non-U.S. nativity also tend to show better health than those born in the United States, although this advantage dissipates with increasing time spent in the United States. The current article discusses the Reserve Capacity Model (L.C. Gallo & K. A. Matthews, 2003) as a potential framework for understanding how psychosocial risk and resilient factors may contribute to health disparities associated with broad sociocultural factors, such as low socioeconomic status or minority ethnicity. In addition, we examine theory concerning features of the Hispanic culture that may enhance resilience (e.g., social resources, familism, religiousness; G. Marin & B. V. Marin, 1991) in the face of adverse circumstances. We summarize some of our recent work that has empirically tested effects of risk and resilient factors in Hispanic health in the contexts of prostate cancer and cardiovascular disease. We conclude by discussing future directions and opportunities for researchers interested in culture-specific resiliency factors in relation to health outcomes.

Association of acculturation with cardiac structure and function among Hispanics/Latinos: a cross-sectional analysis of the echocardiographic study of Latinos.

OBJECTIVE: Hispanics/Latinos, the largest immigrant population in the USA, undergo the process of acculturation and have a large burden of heart failure risk. Few studies have examined the association of acculturation on cardiac structure and function. DESIGN: Cross-sectional. SETTING: The Echocardiographic Study of Latinos. PARTICIPANTS: 1818 Hispanic adult participants with baseline echocardiographic assessment and acculturation measured by the Short Acculturation Scale, nativity, age at immigration, length of US residence, generational status and language. PRIMARY AND SECONDARY OUTCOME MEASURES: Echocardiographic assessment of left atrial volume index (LAVI), left ventricular mass index (LVMI), early diastolic transmitral inflow and mitral annular velocities. RESULTS: The study population was predominantly Spanish-speaking and foreign-born with mean residence in the US of 22.7 years, mean age of 56.4 years; 50% had hypertension, 28% had diabetes and 44% had a body mass index >30 kg/m2. Multivariable analyses demonstrated higher LAVI with increasing years of US residence. Foreign-born and first-generation participants had higher E/e' but lower LAVI and e' velocities compared with the second generation. Higher acculturation and income >$20K were associated with higher LVMI, LAVI and E/e' but lower e' velocities. Preferential Spanish-speakers with an income <$20K had a higher E/e'. CONCLUSIONS: Acculturation was associated with abnormal cardiac structure and function, with some effect modification by socioeconomic status.

Association of dispositional optimism with Life's Simple 7's Cardiovascular Health Index: results from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) Sociocultural Ancillary Study (SCAS).

OBJECTIVES: Mounting evidence links positive psychological functioning to restorative health processes and favourable medical outcomes. However, very little is known about the relationship between optimism, an indicator of psychological functioning and the American Heart Association (AHA)-defined concept of cardiovascular health (CVH), particularly in Hispanics/Latinos of diverse backgrounds. To address limitations of existing literature, this study investigated the association between dispositional optimism and CVH in a heterogeneous sample of Hispanics/Latinos residing in the USA. DESIGN: Cross-sectional study. PARTICIPANTS AND SETTING: Data were analysed from 4919 adults ages 18-75 of the Hispanic Community Health Study/Study of Latinos parent study and the Sociocultural Ancillary Study. MAIN OUTCOME MEASURES: Optimism was assessed using the 6-item Life Orientation Test-Revised (range from 6 to 30). AHA classification standards were used to derive an additive CVH score with operationalisation of indicators as Ideal, Intermediate and Poor. The overall CVH score included indicators of diet, body mass index, physical activity, cholesterol, blood pressure, fasting glucose and smoking status. Multivariate linear and logistic regressions were used to examine associations of optimism with CVH (Life's Simple 7), after adjusting for sociodemographic factors and depressive symptoms. RESULTS: Each increase in the optimism total score was associated with a greater CVH score (ß=0.03 per unit increase, 95% CI 0.01 to 0.05). When modelling tertiles of optimism, participants with moderate (ß=0.24 to 95% CI 0.06 to 0.42) and high (ß=0.12, 95% CI 0.01 to 0.24) levels of optimism displayed greater CVH scores when compared with their least optimistic peers. CONCLUSION: This study offers preliminary evidence for an association between optimism and CVH in a large heterogeneous group of Hispanic/Latino adults. Our study adds scientific knowledge of psychological assets that may promote CVH and suggests a novel therapeutic target for consideration. Future studies are needed to explore causality and potential mechanism underlying the relationship between positive emotion and heart health.

Machismo, Marianismo, and Negative Cognitive-Emotional Factors: Findings From the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study.

There is limited research on the traditional Hispanic male and female gender roles of machismo and marianismo, respectively, in relation to negative cognitions and emotions. Given the vulnerability of Hispanics to negative cognitions and emotions, it is important to examine sociocultural correlates of emotional distress. Therefore, we examined associations of machismo and marianismo with negative cognitive-emotional factors (i.e., depression symptoms; cynical hostility; and trait anxiety and anger) in the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study, a cross-sectional cohort study of sociocultural and psychosocial correlates of cardiometabolic health. Participants were aged 18-74 years and self-identified as Hispanic of Central American, Cuban, Dominican, Mexican, Puerto Rican, South American, and other Hispanic background (N = 4,426). Results revealed that specific components of machismo (traditional machismo) and marianismo (family and spiritual pillar dimensions) were associated with higher levels of negative cognitions and emotions after adjusting for socio-demographic factors (p < .05); these associations remained consistent across sex, Hispanic background group, and acculturation. Findings can inform mental health interventions and contribute to our understanding of the importance of gender role socialization in the context of self-reported negative cognitive-emotional factors in Hispanics.

Self-Reported Cancer Prevalence among Hispanics in the US: Results from the Hispanic Community Health Study/Study of Latinos.

Cancer has surpassed heart disease as the leading cause of death among Hispanics in the U.S., yet data on cancer prevalence and risk factors in Hispanics in regard to ancestry remain scarce. This study sought to describe (a) the prevalence of cancer among Hispanics from four major U.S. metropolitan areas, (b) cancer prevalence across Hispanic ancestry, and (c) identify correlates of self-reported cancer prevalence. Participants were 16,415 individuals from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), who self-identified as Cuban, Dominican, Mexican, Puerto Rican, Central or South American. All data were collected at a single time point during the HCHS/SOL baseline clinic visit. The overall self-reported prevalence rate of cancer for the population was 4%. The rates varied by Hispanic ancestry group, with individuals of Cuban and Puerto Rican ancestry reporting the highest cancer prevalence. For the entire population, older age (OR = 1.47, p < .001, 95% CI, 1.26-1.71) and having health insurance (OR = 1.93, p < .001, 95% CI, 1.42-2.62) were all significantly associated with greater prevalence, whereas male sex was associated with lower prevalence (OR = 0.56, p < .01, 95% CI, .40-.79). Associations between study covariates and cancer prevalence also varied by Hispanic ancestry. Findings underscore the importance of sociodemographic factors and health insurance in relation to cancer prevalence for Hispanics and highlight variations in cancer prevalence across Hispanic ancestry groups. Characterizing differences in cancer prevalence rates and their correlates is critical to the development and implementation of effective prevention strategies across distinct Hispanic ancestry groups.

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.

Neurocognitive function among middle-aged and older Hispanic/Latinos: results from the Hispanic Community Health Study/Study of Latinos.

We sought to examine and describe neurocognitive function among middle-aged and older Hispanic/Latino Hispanic Community Health Study/Study of Latinos (HCHS/SOL) participants. We analyzed baseline cross-sectional data from the middle-aged and older (ages 45-74 years old) participants (n = 9,063) to calculate neurocognitive function scores and their correlates. Older age and higher depressive symptoms scores were associated with lower average neurocognitive performance, whereas greater educational attainment and household income were associated with higher neurocognitive performance. Hispanic/Latino heritage groups significantly varied in neurocognitive performances. Some neurocognitive differences between Hispanics/Latinos were maintained after controlling for language preference, education, household income, and depressive symptoms. We found notable differences in neurocognitive scores between Hispanic/Latino heritage groups that were not fully explained by the cultural and socioeconomic correlates examined in this study. Further investigations into plausible biological and environmental factors contributing to the Hispanic/Latino heritage group differences in neurocognitive found in the HCHS/SOL are warranted.

Do all components of the metabolic syndrome cluster together in U.S. Hispanics/Latinos? Results from the Hispanic Community Health study/Study of Latinos.

PURPOSE: Metabolic syndrome (MetS), the clustering of several risk factors for cardiovascular disease, is highly prevalent in Hispanics/Latinos. We tested whether all components significantly loaded on the syndrome in Hispanics/Latinos and whether their contribution differed by sex and Hispanic ancestry. We also examined associations of MetS with prevalent diabetes and coronary heart disease in Hispanics/Latinos. METHODS: Data were obtained from a population-based cohort of n = 15,823 participants in the HCHS/SOL study who self-identified as being of Central American, Cuban, Dominican, Mexican American, Puerto Rican, or South American ancestry and were aged 18 to 74 years at screening. RESULTS: A latent variable model of waist circumference, systolic and diastolic blood pressure, triglycerides, high-density lipoprotein cholesterol (HDL-C), and fasting glucose fit the data in men and women, but the contribution of HDL-C was weak. No difference in the latent model of MetS was detected across Hispanic/Latino ancestry groups. MetS was significantly associated with diabetes and coronary heart disease. CONCLUSIONS: Our results indicate that similar criteria for MetS may be applied across Hispanic/Latino ancestry groups but call into question the role of HDL-C in classifying the MetS in Hispanics/Latinos.
