Comparison of genetic and health risk factors for mild cognitive impairment and Alzheimer's disease between Hispanic and non-Hispanic white participants. Alzheimers Dement 2023; 19:5086-5094. [PMID: 37104247 DOI: 10.1002/alz.13110] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Revised: 03/28/2023] [Accepted: 04/03/2023] [Indexed: 04/28/2023]
Abstract
INTRODUCTION The influence of apolipoprotein E (APOE) genotype on mild cognitive impairment (MCI) and Alzheimer's disease (AD) is well studied in the non-Hispanic white (NHW) population but not in the Hispanic population. Additionally, health risk factors such as hypertension, stroke, and depression may also differ between the two populations. METHODS We combined three data sets (National Alzheimer's Coordinating Center [NACC], Alzheimer's Disease Neuroimaging Initiative [ADNI], Health and Aging Brain Study: Health Disparities [HABS-HD]) and compared risk factors for MCI and AD between Hispanic and NHW participants, with a total of 24,268 participants (11.1% Hispanic). RESULTS APOEε4 was associated with fewer all-cause MCI cases in Hispanic participants (Hispanic odds ratio [OR]: 1.114; NHW OR: 1.453), and APOEε2 (Hispanic OR: 1.224; NHW OR: 0.592) and depression (Hispanic OR: 2.817; NHW OR: 1.847) were associated with more AD cases in Hispanic participants. DISCUSSION APOEε2 may not be protective for AD in Hispanic participants and Hispanic participants with depression may face a higher risk for AD. HIGHLIGHTS GAAIN allows for discovery of data sets to use in secondary analyses. APOEε2 was not protective for AD in Hispanic participants. APOEε4 was associated with fewer MCI cases in Hispanic participants. Depression was associated with more AD cases in Hispanic participants.

Abstract
Poor sleep and different patterns of marital status among Hispanics/Latinos have been documented, yet the extent to which marital status is associated with sleep health and the moderating role of gender in this association among Hispanics/Latinos is poorly understood.Demographic and sleep data were obtained from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL: n= 16,415), an epidemiological cohort study, and the Sueño Study (n= 2,252) that is an ancillary to HCHS/SOL. Sleep duration, insomnia symptoms, daytime sleepiness, napping, and snoring were self-reported and drawn from HCHS/SOL. Sleep efficiency, sleep fragmentation, and inter-day stability were objectively assessed in the Sueño Study.Complex sample analyses indicated that being married or cohabiting was associated with better sleep health in general, including having normal sleep duration, fewer insomnia symptoms, and higher sleep efficiency (F> 2.804, p< .044). These associations were more prominent in objectively measured sleep indices and among females.Findings suggest being in a committed relationship associated with better sleep health in Hispanics/Latinos in the US, a diverse and under-represented population. Findings may have implications for tailoring sleep health interventions to at-risk populations who may less likely to be in a committed relationship.

Abstract
OBJECTIVE/BACKGROUND Short and long sleep duration, later sleep midpoint, and greater intra-individual sleep variability are associated with lower physical activity, but previous research lacks objective and concurrent assessment of sleep and physical activity. This cross-sectional study examined whether sleep duration, midpoint, and variability in duration and midpoint were related to wrist actigraphy-measured physical activity. PARTICIPANTS Participants were 2156 Hispanics/Latinos in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) Sueño Ancillary Study. METHODS Participants wore Actiwatch devices to measure sleep and physical activity via the wrist for ≥5 days. Physical activity was defined as minutes/day in the upper quartile of the sampling distribution's non-sleep activity, capturing light to vigorous physical activity. RESULTS An inverse linear relationship between sleep duration and physical activity was found such that each additional sleep hour related to 29 fewer minutes of physical activity (B = -28.7, SE = 3.8), p < .01). Variability in sleep midpoint was also associated with physical activity; with each 1-hr increase in variability there were 24 more minutes of physical activity (B = 24.2, SE = 5.6, p < .01). In contrast, sleep midpoint and variability in duration were not associated with physical activity. Sensitivity analyses identified an association of short sleep duration and greater variability in sleep duration with greater accelerometry-derived moderate-to-vigorous physical activity measured at the HCHS/SOL baseline (M = 2.1 years before the sleep assessment). CONCLUSIONS Findings help clarify inconsistent prior research associating short sleep duration and sleep variability with greater health risks but also contribute novel information with simultaneous objective assessments.

Abstract
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.

Abstract
Although increasing emotional well-being has been proposed as a potential pathway to drive cardiac health, emotional well-being interventions for people with cardiac risk are underdeveloped, particularly among Hispanic/Latino adults. Our objective was to pilot a well-being intervention drawing on positive psychology concepts to determine feasibility and acceptability in Hispanics/Latinos at risk for cardiovascular disease (CVD). We developed a Spanish-language positive psychological intervention, with cultural tailoring informed by formative qualitative work, to promote emotional well-being and its antecedents in Hispanics/Latinos. Hispanic/Latino adults (n = 19) self-reporting two or more CVD risk factors were enrolled in our single-arm 8-week pilot trial. The group intervention consisted of 8 weekly 90-min sessions delivered by a bilingual licensed clinical social worker. Mean age was 54.1 years, 68.8% were female, and 50% had ≤eighth-grade education. Eleven of 19 Hispanic/Latino adults completed the 8-week program for a 57.89% retention rate, with a majority of factors leading to dropout unrelated to program content or mode of delivery. Most participants felt satisfied overall with each session (97.1%). Largest increases relative to baseline after receiving the intervention were found in engagement in happiness-inducing behaviors (e.g., meditation), emotional vitality, and subjective happiness using metrics of reliable change and effect sizes. This single-arm trial documented adequate feasibility and acceptability, although strategies to increase retention are warranted. Future studies should test our intervention using a randomized trial design with a larger sample size and inclusion of biomarkers (e.g., C-reactive protein) to document impact of our intervention on cardiac-related health.

Abstract
Background The role of acculturation in dietary behaviors among Hispanics/Latinos in the United States remains unclear. Discrepancies may be explained by variations in acculturation constructs or ethnicity-specific dynamics. Objective We aimed to compare relations between 3 different acculturation constructs with dietary quality and patterns among Puerto Ricans in the mainland United States. Methods We analyzed cross-sectional data with 1194-1380 Puerto Ricans, aged 45-75 y. Acculturation was measured with the use of a language-based scale (0-100; higher score denotes more English use), a psychological-based scale (0-50; higher score denotes stronger US orientation), and years living in the mainland United States. Diet quality scores (higher scores denote healthier diet) were defined with the use of the Alternate Healthy Eating Index-2010 (AHEI) and the Mediterranean Diet Score (MeDS). Three dietary patterns were previously derived with the use of principal components analysis. Adjusted multivariable regression models tested the association of each acculturation construct with diet quality score or pattern. Interaction terms were included for income or education status. Results Psychological-based acculturation, but not the other constructs, was positively associated with AHEI (β ± SE: 0.013 ± 0.004; P = 0.002) and MeDS (0.009 ± 0.005; P = 0.041). Income, but not education, moderated this association (P = 0.03), with higher diet quality observed with higher income (>$25,000) and stronger US orientation. All constructs were inversely associated with a traditional dietary pattern, with the language-based scale being stronger (z score β ± SE: -0.160 ± 0.032; P < 0.0001) than the psychological-based scale (-0.097 ± 0.028; P = 0.001) or years living in the mainland United States (-0.058 ± 0.028; P = 0.041). No associations were observed for the Western or sweets/desserts patterns. Conclusions In Puerto Rican adults, stronger psychological US orientation was associated with higher diet quality, particularly with higher income. More Spanish use, stronger psychological Puerto Rican orientation, and shorter length of mainland-US residency were associated with traditional dietary patterns. Appropriate diet-related acculturation constructs should be carefully considered among Hispanics/Latinos. This trial was registered at clinicaltrials.gov as NCT01231958.

Does the Immigrant Advantage in Overweight/Obesity Persist over Time in Mexican American Youth? NHANES 1988-1994 to 2005-2014. Obesity (Silver Spring) 2018; 26:1057-1062. [PMID: 29797556 PMCID: PMC5975978 DOI: 10.1002/oby.22178] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2017] [Revised: 01/30/2018] [Accepted: 02/24/2018] [Indexed: 11/06/2022]
Abstract
OBJECTIVE To examine whether the relationship between nativity and overweight/obesity has changed over time among Mexican American children and to investigate the implications of this pattern on overweight/obesity disparities relative to non-Hispanic white children. METHODS Using cross-sectional data from Mexican American and non-Hispanic white children aged 4 to 17 years participating in the National Health and Nutrition Examination Surveys (1988-1994 [N = 4,720] and 2005-2014 [N = 7,275]) log-binomial regression was used to calculate prevalence ratios (PRs) of overweight/obesity by nativity status adjusting for sociodemographic covariates, survey period, and a nativity-by-survey period interaction. A separate covariate-adjusted model tested a three-level interaction between ethnicity, nativity, and survey period that included non-Hispanic white children. RESULTS In 1988-1994, foreign-born Mexican Americans had significantly lower prevalence of overweight/obesity compared with US-born Mexican Americans (PR = 0.75, 95% CI: 0.61-0.94). However, by 2005-2014, the nativity gap in overweight/obesity had closed (PR = 0.94, 95% CI: 0.84-1.07). Moreover, while foreign-born Mexican Americans had the lowest levels of overweight/obesity in 1988-1994, by 2005-2014, foreign-born and US-born Mexican Americans had comparable estimates, both significantly higher than that of non-Hispanic white individuals. CONCLUSIONS Although overweight/obesity disparities between Mexican Americans and non-Hispanic white Americans had previously been specific to US-born Mexican Americans, disparities in more recent years have extended to foreign-born Mexican Americans.

Abstract
Background Away-from-home foods (AFHFs) influence diet quality, a modifiable obesity risk factor, with limited generalizable evidence in Hispanic/Latino adults. Objective We investigated associations between AFHF intake with diet quality and overweight or obesity among US Hispanic/Latino adults. Methods Cross-sectional baseline (2008-2011) analyses included adults (n = 16,045) aged 18-74 y in the national Hispanic Community Health Study/Study of Latinos. Participants self-reported AFHF consumption frequency from 10 different settings and dietary intake (2-d 24-h recall). The Alternate Healthy Eating Index-2010 (AHEI-2010) was used to measure diet quality; higher scores indicated a healthier diet and scores were categorized into tertiles. WHO classifications categorized overweight [body mass index (BMI; kg/m2): 25.0-29.9] and obesity (BMI ≥30). Multivariate-adjusted associations of AFHF frequency or type with AHEI-2010, overweight, or obesity were assessed by using complex survey logistic regression (ORs and 95% CIs). Results Almost half of participants (47.1%) reported eating AFHFs ≥5 times/wk. The mean ± SE AHEI-2010 score was 47.5 ± 0.2. More than one-third (37.2%) were classified as overweight and 39.6% classified as obese. Compared with consuming AFHFs ≥5 times/wk, consuming AFHFs <1 time/wk or 1-2 times/wk was associated with greater odds of being in higher AHEI-2010 tertiles, indicating a healthier diet [<1 time/wk-tertile 2: OR (95% CI): 1.6 (1.4, 1.9); tertile 3: 2.5 (2.1, 3.1); 1-2 times/wk-tertile 2: OR (95% CI): 1.4 (1.2, 1.6); tertile 3: 1.5 (1.2, 1.8)]. Consumption of AFHFs ≥1 time/wk from each AFHF setting, compared with consumption of any AFHFs <1 time/wk was associated with lower odds of being in higher AHEI-2010 tertiles. Increasing AFHF intake frequency was not associated with odds of overweight or obesity. Eating from on-street vendors ≥1 time/wk was associated with obesity (OR: 1.5; 95% CI: 1.1, 2.0). Conclusions Consumption of AFHFs was prevalent among Hispanic/Latino adults and was associated with poorer diet quality. Findings may help to identify dietary targets to improve diet quality and prevent obesity in US Hispanics/Latinos.

Abstract
The Center for Epidemiologic Studies Depression Scale (CES-D) is a widely used self-report measure of depression symptomatology. This study evaluated the reliability, validity, and measurement invariance of the CES-D 10 in a diverse cohort of Hispanics/Latinos from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). The sample consisted of 16,415 Hispanic/Latino adults recruited from 4 field centers (Miami, FL; San Diego, CA; Bronx, NY; Chicago, IL). Participants completed interview administered measures in English or Spanish. The CES-D 10 was examined for internal consistency, test-retest reliability, convergent validity, and measurement invariance. The total score for the CES-D 10 displayed acceptable internal consistencies (Cronbach's alpha's = .80-.86) and test-retest reliability (r values = .41-.70) across the total sample, language group and ethnic background group. The total CES-D 10 scores correlated in a theoretically consistent manner with the Spielberger State-Trait Anxiety Inventory, r = .72, p < .001, the Patient Health Questionnaire-9 depression measure, r = .80, p < .001, the Short Form-12's Mental Component Summary, r = -.65, p < .001, and Physical Component Summary score, r = -.25, p < .001. A confirmatory factor analysis showed that a 1-factor model fit the CES-D 10 data well (CFI = .986, RMSEA = .047) after correlating 1 pair of item residual variances. Multiple group analyses showed the 1-factor structure to be invariant across English and Spanish speaking responders and partially invariant across Hispanic/Latino background groups. The total score of the CES-D 10 can be recommended for use with Hispanics/Latinos in English and Spanish. (PsycINFO Database Record

Abstract
BACKGROUND Low health literacy is associated with poor medication adherence in persons with human immunodeficiency virus (HIV), which can lead to poor health outcomes. As linguistic minorities, Spanish-dominant Hispanics (SDH) face challenges such as difficulties in obtaining and understanding accurate information about HIV and its treatment. Traditional health educational methods (e.g., pamphlets, talking) may not be as effective as delivering through alternate venues. Technology-based health information interventions have the potential for being readily available on desktop computers or over the Internet. The purpose of this research was to adapt a theoretically-based computer application (initially developed for English-speaking HIV-positive persons) that will provide linguistically and culturally appropriate tailored health education to Spanish-dominant Hispanics with HIV (HIV + SDH). METHODS A mixed methods approach using quantitative and qualitative interviews with 25 HIV + SDH and 5 key informants guided by the Information-Motivation-Behavioral (IMB) Skills model was used to investigate cultural factors influencing medication adherence in HIV + SDH. We used a triangulation approach to identify major themes within cultural contexts relevant to understanding factors related to motivation to adhere to treatment. From this data we adapted an automated computer-based health literacy intervention to be delivered in Spanish. RESULTS Culture-specific motivational factors for treatment adherence in HIV + SDH persons that emerged from the data were stigma, familismo (family), mood, and social support. Using this data, we developed a culturally and linguistically adapted a tailored intervention that provides information about HIV infection, treatment, and medication related problem solving skills (proven effective in English-speaking populations) that can be delivered using touch-screen computers, tablets, and smartphones to be tested in a future study. CONCLUSION Using a theoretically-grounded Internet-based eHealth education intervention that builds on knowledge and also targets core cultural determinants of adherence may prove a highly effective approach to improve health literacy and medication decision-making in this group.

Abstract
The Interpersonal Support Evaluation List-12 (ISEL-12; Cohen, Mermelstein, Kamarck, & Hoberman, 1985) is broadly employed as a short-form measure of the traditional ISEL, which measures functional (i.e., perceived) social support. The ISEL-12 can be scored by summing the items to create an overall social support score; three subscale scores representing appraisal, belonging, and tangible social support have also been proposed. Despite extensive use, studies of the psychometric properties of ISEL-12 scores have been limited, particularly among Hispanics/Latinos, the largest and fastest growing ethnic group in the United States. The current study investigated the reliability and structural and convergent validity of ISEL-12 scores using data from 5,313 Hispanics/Latinos who participated in the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study. Participants completed measures in English or Spanish and identified their ancestry as Dominican, Central American, Cuban, Mexican, Puerto Rican, or South American. Cronbach's alphas suggested adequate internal consistency for the total score for all languages and ancestry groups; coefficients for the subscale scores were not acceptable. Confirmatory factor analyses revealed that the one-factor and three-factor models fit the data equally well. Results from multigroup confirmatory factor analyses supported a similar one-factor structure with equivalent response patterns and variances between language groups and ancestry groups. Convergent validity analyses suggested that the total social support score related to scores of social network integration, life engagement, perceived stress, and negative affect (depression, anxiety) in the expected directions.

Abstract
OBJECTIVE Recent guidelines highlight the importance of improving cardiovascular health in the general population in addition to disease prevention among high risk individuals. We investigated factors associated with ethnic and nativity-related differences in the prevalence of low cardiovascular risk (optimal levels of all major cardiovascular risk factors). METHODS We used logistic regression to estimate differences in likelihood of being low risk (not currently smoking; no diabetes; untreated total cholesterol <200mg/dL; untreated blood pressure <120/<80; and body mass index <25 kg/m(2)) among 8693 foreign- and U.S.-born Mexican-American and non-Hispanic White 2003-2008 U.S. National Health and Nutrition Examination Survey participants before and after adjustment for socioeconomic, lifestyle, and acculturation-related factors. RESULTS Foreign-born Mexican-Americans were more likely to be low risk than non-Hispanic Whites after adjustment for all covariates (Odds Ratio [OR]: 1.53; 95% Confidence Interval [CI]: 1.00, 2.34). In contrast, U.S.-born Mexican-Americans were less likely to be low risk compared to Whites (OR: 0.60; 95% CI: 0.43, 0.84). Differences between foreign-born and U.S.-born Mexican-Americans were largely attenuated after adjustment for acculturation indicators. CONCLUSIONS Our findings support the healthy migrant hypothesis and suggest that acculturation-related factors may be important drivers of ethnic and nativity-related differences in low cardiovascular risk.

Estimates of the population prevalence of injection drug users among hispanic residents of large US metropolitan areas. J Urban Health 2012; 89:527-64.

Abstract
Little information exists on the population prevalence or geographic distribution of injection drug users (IDUs) who are Hispanic in the USA. Here, we present yearly estimates of IDU population prevalence among Hispanic residents of the 96 most populated US metropolitan statistical areas (MSAs) for 1992-2002. First, yearly estimates of the proportion of IDUs who were Hispanic in each MSA were created by combining data on (1) IDUs receiving drug treatment services in Substance Abuse and Mental Health Services Administration (SAMHSA)'s Treatment Entry Data System, (2) IDUs being tested in the Centers for Disease Control and Prevention (CDC) HIV-Counseling and Testing System, and (3) incident AIDS diagnoses among IDUs, supplemented by (4) data on IDUs who were living with AIDS. Then, the resulting proportions were multiplied by published yearly estimates of the number of IDUs of all racial/ethnic groups in each MSA to produce Hispanic IDU population estimates. These were divided by Hispanic population data to produce population prevalence rates. Time trends were tested using mixed-effects regression models. Hispanic IDU prevalence declined significantly on average (1992 mean = 192, median = 133; 2002 mean = 144, median = 93; units are per 10,000 Hispanics aged 15-64). The highest prevalence rates across time tended to be in smaller northeastern MSAs. Comparing the last three study years to the first three, prevalence decreased in 82% of MSAs and increased in 18%. Comparisons with data on drug-related mortality and hepatitis C mortality supported the validity of the estimates. Generally, estimates of Hispanic IDU population prevalence were higher than published estimates for non-Hispanic White residents and lower than published estimates for non-Hispanic Black residents. Further analysis indicated that the proportion of IDUs that was Hispanic decreased in 52% and increased in 48% of MSAs between 2002 and 2007. The estimates resulting from this study can be used to investigate MSA-level social and economic factors that may have contributed to variations across MSAs and to help guide prevention program planning for Hispanic IDUs within MSAs. Future research should attempt to determine to what extent these trends are applicable to Hispanic national origin subgroups.

Abstract
OBJECTIVES This study examines the relationship between depressive symptoms and walking behavior across 30 months in a prospective study of 217 community-dwelling, Hispanic older adults in Miami, Florida (ages 70-100 years). METHOD Analyses examine the direction of the relationship between depressive symptoms and physical activity (i.e., walking) over time, as well as test for a potential bi-directional or reciprocal relationship between these two variables. RESULTS Structural equation modeling (SEM) with a cross-lagged panel design revealed that walking was unrelated to subsequent depressive symptoms. However, depressive symptoms were related to subsequent walking behavior at every time-point, such that higher levels of depressive symptoms were predictive of less walking in the future. Older adults who had clinically-relevant depressive symptoms at the initial assessment had 1.34 times the risk of not walking 30 months later, compared to older adults without clinically-relevant depressive symptoms. CONCLUSION Results support the need for primary care providers to evaluate and address depressive symptoms among older adults, as a means of reducing sedentary behavior and potentially improving health. Further research on the prevention and management of depressive symptoms and sedentary behavior is needed, given the morbidity related to both of these health risks, particularly for minority and low-socio-economic status (SES) older adults.
