Abstract
PURPOSE The purpose of the study was to explore the feasibility of using commonly available technology, such as text messaging, for diabetes prevention in rural Mexican American communities during COVID-19. METHODS Participants were selected from a diabetes prevention study funded by the National Institutes of Health that, prior to COVID-19, involved in-person group intervention sessions. Participants were predominantly female adults born in Mexico and Spanish-speaking. A subsample (n = 140) was divided into 3 cohorts: (1) 50 who completed the initial in-person intervention prior to the COVID-19 research pause, (2) 60 who needed additional support sessions to complete the intervention and thus received 10 text messages with links to relevant online diabetes prevention videos (TM+), and (3) 30 who received enhanced usual care involving health guidance offered during data collection (control). Repeated measures analysis of covariance was used to evaluate cohort differences at 24 months post baseline. RESULTS No significant cohort differences were found for depression, eating self-efficacy, alcohol intake, fat avoidance, or sedentary behaviors. Differences in A1C showed both in-person and TM+ cohorts having lower mean A1C levels (5.5%) than the control cohort (5.7%). The TM+ cohort had lower body mass index than other cohorts and a lower diabetes conversion rate (22.2%) compared to the control cohort (28%). Participants indicated preferences for in-person/TM+ combination interventions. The strongest positive feedback was for the TM+ intervention cooking demonstration videos. CONCLUSIONS Augmented text messaging combined with in-person sessions had similar outcomes to the all in-person strategy and thus has the potential for expanding the reach of diabetes prevention to many Mexican American communities.

Patterns of Alcohol Use in Hispanic Individuals with TBI over the Ten Years Post-Injury: A Model Systems Study. J Pers Med 2024; 14:105. [PMID: 38248806 PMCID: PMC10817313 DOI: 10.3390/jpm14010105] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 12/22/2023] [Accepted: 01/12/2024] [Indexed: 01/23/2024] Open
Abstract
The study's aim was to examine alcohol consumption patterns and predictors of consumption across time among Hispanics with traumatic brain injury (TBI) in the U.S. within ten years post-injury. This longitudinal cohort study included 1342 Hispanic individuals (77.6% males) from the multi-site, longitudinal TBI Model Systems (TBIMS) database. The main outcome measures were consumption information, demographic, and injury characteristics. Across the full sample, alcohol consumption variables generally demonstrated quadratic movement characterized by an initial increase followed by a plateau or slight decrease over the ten years post-injury. The predictors of higher consumption were being men, single, with a history of excessive alcohol use, with a nonviolent mechanism of injury, shorter duration of PTA, and higher levels of education. Participants had a greater number of 5+ drinks/episode occurrences in the past month if they were men and had had a greater number of 5+ drinks/episode occurrences in the month before injury. There was no differential change in alcohol consumption over time as a function of these predictors. This study identified a profile of at-risk Hispanics with TBI for increased alcohol consumption. These individuals should be identified and targeted for early evidence-based alcohol intervention after TBI when results might be most favorable.

Hemoglobin β-Globin Variants In Hispanic Patients: An Institutional Experience From Dallas, Texas. Hemoglobin 2023; 47:167-171. [PMID: 37782073 DOI: 10.1080/03630269.2023.2263356] [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: 07/27/2023] [Accepted: 09/20/2023] [Indexed: 10/03/2023]
Abstract
Hemoglobinopathies are the most common single-gene disorders in humans. There are 1,424 variants of human hemoglobin described with 951 involving the β-globin gene. Ancestry and geography play a significant role in the incidence and nature of hemoglobinopathies, with African, Asian, and Mediterranean populations and their descendants being amongst the most affected. Investigation of variants in individuals of Hispanic descent is needed to reflect the changing demographics of the United States. Hemoglobin β-globin evaluation through gel electrophoresis, high-performance liquid chromatography, and HBB gene sequencing was performed on patients from Texas hospitals between 2010 and 2015 and demographic parameters (age, sex, ethnicity) was subsequently analyzed. A total of 846 patients underwent hemoglobinopathy evaluation. A β chain variant was detected in 628 of the 846 total patients. Hispanic patients represented 37% (314/846 patients), which were equally distributed between females (50%; 156/314) and males (50%; 156/314). A β-globin chain variant was found in 67% of Hispanic patients with a distribution across 10 variants seen in greater than 1% of patients. For hemoglobin variants, an understanding of the regional and ethnic prevalence will improve patient care through more effective screening and identification of the variant, early diagnosis, and appropriate treatment if necessary, and better genetic counseling.

Abstract
Older people are at high risk of developing and dying from pulmonary infections like tuberculosis (TB), but there are few studies among them, particularly in Hispanics. To address these gaps, we sought to identify host factors associated with TB and adverse treatment outcomes in older Hispanics by conducting a cross-sectional study of TB surveillance data from Tamaulipas, Mexico (2006-2013; n = 8381). Multivariable logistic regressions were assessed for older adults (OA ≥65 years) when compared to young (YA, 18-39 years) and middle-aged adults (40-64 years). We found that the OA had features associated with a less complicated TB (e.g., lower prevalence of extra-pulmonary TB and less likely to abandon treatment or have drug resistant TB), and yet, were more likely to die during TB treatment (adj-OR 3.9, 95% 2.5, 5.25). Among the OA, excess alcohol use and low body mass index increased their odds of death during TB treatment, while a higher number of reported contacts (social support) was protective. Diabetes was not associated with adverse outcomes in OA. Although older age is a predictor of death during TB disease, OA are not prioritized by the World Health Organization for latent TB infection screening and treatment during contact investigations. With safer, short-course latent TB infection treatment available, we propose the inclusion of OA as a high-risk group in latent TB management guidelines.

Abstract
INTRODUCTION Individuals with melanin-rich skin account for the majority of the world's population. However, literature data regarding dermatoscopic characteristics of skin cancer in skin of color (SoC) are scarce. The dermatoscopic characteristics of cutaneous tumors might differ among skin types due to heterogeneity in composition and pigmentation. OBJECTIVES To summarize literature data on the dermatoscopic findings of skin neoplasms, according to the skin color and race. METHODS The literature search was performed using PubMed database up to December 30, 2022 and was conducted with the use of terms referring to dermatoscopy, race (Caucasians, Hispanics, Asians, and Black/African) and skin cancer types (BCC, SCC, keratoacanthoma, Bowen's disease and melanoma). RESULTS In total, 30 race-specific records were included. 9 SoC records for BCCs (2 BCC studies in Hispanics, 1 BCC study in Black individuals and 6 BCC studies in Asians ), 9 SoC records for SCCs ( 1 SCC study in Hispanics, 1 SCC study in Black individuals and 7 SCCs in Asian population) and 8 SoC records for melanoma (2 melanoma studies in Hispanics, 1 melanoma study in Blacks and 5 melanoma studies in Asians) were compared with 4 records that involved only Caucasian population, according to their participant section as well as with studies on dermatoscopy characteristics without focusing on race origins and phototype of the patient. In Hispanics and in both fair and dark-skinned Asians, BCCs were more often pigmented or at least with pigmented structures on dermoscopy. Squamous cell carcinoma (SCC) and keratoacanthoma were the least studied in SoC patients. Bowen's disease in SoC patients can be pigmented in a higher frequency compared to Caucasians, with glomerular vessels and a squamous surface being the most common dermatoscopic findings. The most frequent pattern of melanomas in SoC individuals were the parallel ridge pattern in palmoplantar region. CONCLUSION Based on a review of studies including Caucasians, Hispanics, Asians and Blacks /Africans, SoC patients present with more frequent and unique dermatoscopy features of skin cancers.

Effects of caregiver-child acculturation on child obesity among US Latino individuals. Obesity (Silver Spring) 2023; 31:2103-2109. [PMID: 37394865 PMCID: PMC10523851 DOI: 10.1002/oby.23791] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Revised: 02/03/2023] [Accepted: 03/27/2023] [Indexed: 07/04/2023]
Abstract
OBJECTIVE The goal of this study was to assess the association of Latino caregiver-child nativity status (US- and foreign-born) with child obesity using a nationally representative sample. METHODS Using data from the National Health and Nutrition Examination Survey (NHANES 1999-2018), this study used generalized linear models to identify associations between caregiver-child nativity status (as a proxy for acculturation) and children's BMI. RESULTS Compared with foreign-born caregiver-child dyads, US-born caregiver-child dyads had 2.35 times the risk of class 2 obesity (95% CI: 1.59-3.47) and 3.60 times the risk of class 3 obesity (95% CI: 1.86-6.96). Foreign-born caregiver and US-born child dyads had 2.01 times the risk of class 2 obesity (95% CI: 1.42-2.84) and 2.47 times the risk of class 3 obesity (95% CI: 1.38-4.44; p < 0.05 for class 2 and class 3). CONCLUSIONS Compared with foreign-born Latino caregiver-child dyads, dyads with US-born caregivers and children and dyads with foreign-born caregivers and US-born children had significantly increased risk across the severe classes of obesity. Examining the influence and relationship of varying acculturation levels in an immigrant household will help guide more effective clinical and policy guidelines surrounding obesity and weight management in both pediatric and adult US Latino populations.

Abstract
Self-rated health (SRH) has been used to predict cognitive decline in various populations; however, this relationship has not been examined in Latinos. This study examines the relationship between SRH and cognition among middle-aged and older Latinos. A cross-sectional analysis was conducted among Latinos (n = 425, Mage = 64.13 ± 7.65, 82% female). Participants rated their health as poor/fair, good, and excellent and completed cognitive performance tests. Analyses of covariance (ANCOVA) examined differences in cognition between SRH categories. ANCOVAs showed significant differences in SRH categories for working memory (F [2, 357] = 3.63, p = .028) and global cognition (F [2, 348] = 3.074, p = .047), such that those who self-rated their health as good had better scores compared to participants in the poor/fair category. Findings show that SRH is associated with cognition among middle-aged and older Latinos. SRH may serve as an indicator of early signs of cognitive decline.

Abstract
Obesity is a serious, chronic disease that is associated with a range of adiposity-based comorbidities, including cardiovascular disease, type 2 diabetes, and nonalcoholic fatty liver disease. In the United States, obesity is a public health crisis, affecting more than 40% of the population. Obesity disproportionately affects Latinx people, who have a higher prevalence of obesity and related comorbidities (such as cardiovascular disease, type 2 diabetes, and nonalcoholic fatty liver disease) compared with the general population. Many factors, including genetic predisposition, environmental factors, traditional calorie-dense Latinx diets, family dynamics, and differences in socioeconomic status, contribute to the increased prevalence and complexity of treating obesity in the Latinx population. Additionally, significant heterogeneity within the Latinx population and disparities in health care access and utilization between Latinx people and the general population add to the challenge of obesity management. Culturally tailored interventions have been successful for managing obesity and related comorbidities in Latinx people. Antiobesity medications and bariatric surgery are also important options for obesity treatment in Latinx people. As highlighted in this review, when managing obesity in the Latinx population, it is critical to consider the impact of genetic, dietary, cultural, and socioeconomic factors, in order to implement an individualized treatment strategy.

Abstract
Triple negative breast cancer (TNBC) is an aggressive type of cancer that accounts for ~23% of breast tumors in Mexico. In an attempt to understand in an improved way the behavior of TNBC, throughout the years, gene expression in these tumors has been studied. Lehman et al identified 6 subtypes of gene expression in TNBC with distinct characteristics. In the present study, it was aimed to assess clinical, pathological and prognostic characteristics of TNBC in a Mexican-based cohort. A total of 55 patients diagnosed with TNBC at Mexico's National Institute of Cancer (INCan) were included. Tumor needle biopsy samples were obtained and subjected to microarray analysis. Patients were thus classified into one of the 6 TNBC molecular subtypes. The prognostic, clinical and pathological information of patients was obtained, and differences across molecular subtypes were sought. Out of the 55 included patients, the following subtypes were identified: 9 basal-like-1, 11 basal-like-2 (BSL2), 16 immunomodulatory (IM), 12 mesenchymal, 6 androgen receptor-like and 1 mesenchymal stem-like. Mean follow-up time was 47.1 months. The IM molecular subtype had the best overall survival (OS) (median OS was not reached). BSL2 had the worst OS (15 months). A complete pathologic response to neoadjuvant chemotherapy was obtained more often in the IM subtype (P=0.032). No significant associations were found between any of the clinical or pathological characteristics and the TNBC molecular subtypes. The results obtained from the present study should be considered when seeking to implement a clinical-molecular model for TNBC patient care, particularly in Hispanic-based populations, as they have been frequently underrepresented in clinical studies assessing TNBC molecular subtypes.

Abstract
PURPOSE OF REVIEW This review provides a 6-year update on the prevalence and treatment of eating disorders among Hispanic/Latinx Americans in the United States. RECENT FINDINGS Prevalence of eating disorders tends to be lower in Hispanic/Latinx American adolescents and adults relative to non-Hispanic White peers. Numerous risk factors for disordered eating symptoms have been identified, including negative body image, depression, sexual assault and culturally specific risk factors, including ethnic discrimination and acculturative stress. Hispanic/Latinx individuals seek treatment less often with the most influential barriers being cost of treatment, eating disorder stigma, eating disorder shame and mental health shame in general. Limited research on the treatment for eating disorders continue to persist. Culturally adapted cognitive behavioural therapy yielded similar outcomes to traditional cognitive behaviour therapy and had better treatment adherence and retention rates. SUMMARY The medical and sociopolitical climate of the United States has changed significantly since our previous review. The need for research on the effectiveness of eating disorder treatments for Hispanic/Latinx Americans remains important for one of the fastest growing populations in the U.S.

Abstract
Objective: Mexican Americans are disproportionally affected by non-alcoholic fatty liver disease (NAFLD), liver fibrosis and hepatocellular carcinoma. Noninvasive means to identify those in this population at high risk for these diseases are urgently needed. Approach: The Cameron County Hispanic Cohort (CCHC) is a population-based cohort with high rates of obesity (51%), type 2 diabetes (28%) and NAFLD (49%). In a subgroup of 564 CCHC subjects, we evaluated 339 genetic variants previously reported to be associated with liver injury markers aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in United Kingdom and Japanese cohorts. Results: Association was confirmed for 86 variants. Among them, 27 had higher effect allele frequency in the CCHC than in the United Kingdom and Japanese cohorts, and 16 had stronger associations with AST and ALT than rs738409 (PNPLA3). These included rs17710008 (MYCT1), rs2519093 (ABO), rs1801690 (APOH), rs10409243 (S1PR2), rs1800759 (LOC100507053) and rs2491441 (RGL1), which were also associated with steatosis and/or liver fibrosis measured by vibration-controlled transient elastography. Main contributors to advanced fibrosis risk were rs11240351 (CNTN2), rs1800759 (LOC100507053), rs738409 (PNPLA3) and rs1801690 (APOH), with advanced fibrosis detected in 37.5% of subjects with 3 of these 4 variants [AOR = 11.6 (95% CI) = 3.8-35.3]. AST- and ALT-associated variants implicated distinct pathways (ethanol and galactose degradation versus antigen presentation and B cell development). Finally, 8 variants, including rs62292950 (DNAJC13), were associated with gut microbiome changes. Conclusion: These genotype-phenotype findings may have utility in risk modeling and disease prevention in this high-risk population.

Abstract
Background. Hospice has been shown to improve patient and family satisfaction with care, reduce hospitalizations and hospital costs, and reduce pain and symptoms. Despite more than 40 years of hospice care and related research in the U.S., few studies examining hospice experiences have included Hispanics. Thus, little is known about hospice barriers, facilitators, and outcomes among Hispanics.Aim. This systematic literature review aimed to provide a comprehensive overview of studies assessing knowledge of and attitudes toward hospice, barriers and facilitators to hospice use, utilization patterns, and hospice-related outcomes among Hispanics.Design. Between March 2019 and March 2020 we searched Ovid Medline (PubMed), EMBASE, and CINAHL, using search terms for hospice care, end-of-life care, Hispanics, and Latinos. All steps were guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols. U.S. studies that examined Hispanics' knowledge and attitudes towards hospice, facilitators or barriers to hospice use, hospice use, and hospice-related outcomes were included. Qualitative studies and non-empirical work were excluded. Study quality was assessed using Hawker's quality criteria.Results. Of the 4,841 abstracts reviewed, 41 peer-reviewed articles met the inclusion criteria. These studies largely report lower hospice knowledge and awareness among Hispanics and mixed results around hospice use and outcomes in comparison to Whites.Conclusion. There has been relatively little research focused specifically on Hispanics' experience with hospice. Future research should focus on testing interventions for overcoming hospice-related disparities among Hispanics and on improving access to quality hospice care among terminally ill Hispanics.

Abstract
BACKGROUND AND AIMS Disparities in gastric cancer incidence and mortality have been reported among ethnic/racial groups. While gastric cancer is not common in the U.S., it is among the top 10 causes of cancer-related death among Hispanics living in Puerto Rico (PRH). This study compared gastric cancer incidence rates during a 15-year period (2002-2006, 2007-2011, and 2012-2016) between PRH and racial/ethnic groups in the mainland U.S., including Non-Hispanic Whites (NHW), Non-Hispanics Blacks (NHB), Hispanics (USH), and Non-Hispanic Asian or Pacific Islanders (NHAPI). METHODS Primary gastric cancer cases (ICD-O-3 codes C16.0 to C16.9) from the Puerto Rico Central Cancer Registry and SEER diagnosed from January 1, 2002 to December 31, 2016 were included in the analysis. The Joinpoint Regression Program and standardized rate ratios were used to estimate Annual Percent Changes (APC) and differences in gastric cancer incidence among racial/ethnic groups, respectively. RESULTS Our analysis included 83,369 gastric cancer cases (PRH n = 4202; NHW n = 43,164; NHB n = 10,414; NHAPI n = 11,548; USH n = 14,041). USH had the highest number of cases among individuals <50 years, whereas NHW and PRH had the highest percentage among individuals ≥50 years. PRH and USH were the only groups with increasing APCs among individuals <50 years. CONCLUSIONS Gastric cancer continues to be a common cancer among PRH, despite the overall decrease in incidence among other racial/ethnic groups. Studies evaluating the gastric cancer risk factors among high-risk groups are necessary to establish health policy and modify gastric cancer screening algorithms among Hispanics.

Abstract
The number of Latinos living with Alzheimer's disease is projected to grow. Latinos currently make one-fifth of U.S. family caregivers. In this paper, we explore the cultural scripts and gendered practice of care in Latino families in relation to the underutilization of services to persons with Alzheimer's disease and related dementias. We conducted interviews with 24 Latino caregivers in Miami-Dade, Florida representing six Latin American countries of origin. Interviews were analyzed using a grounded theory approach. We critically examined the concept of familism in order to better understand in-depth experiences of diverse Latino caregivers and concluded that an ethics of care model better elucidates the complexities of the care experience. Our analysis illustrates the ambivalence, contradictions, and changes in the beliefs and practice of care. These findings can help advance understanding among researchers and providers to develop a formal support system that is responsive to Latino caregiver needs.

Abstract
BACKGROUND Determining amyloid positivity is possible with cerebrospinal fluid and brain imaging of amyloid, but these methods are invasive and expensive. OBJECTIVE To relate plasma amyloid-β (Aβ), measured using Single-molecule array (Simoatrademark) assays, to in vivo brain Aβ, measured using positron emission tomography (PET), examine the accuracy of plasma Aβ to predict brain Aβ positivity, and the relation of APOE ɛ4 with plasma Aβ. METHODS We performed a cross-sectional analysis in a cohort of 345 late middle-aged Hispanic men and women (age 64 years, 72% women). Our primary plasma variable was Aβ42/Aβ40 ratio measured with Simoa. Brain Aβ burden was measured as global SUVR with 18F-Florbetaben PET examined continuously and categorically. RESULTS Plasma Aβ42/Aβ40 ratio was inversely associated with global Aβ SUVR (β= -0.13, 95% Confidence Interval (CI): -0.23, -0.03; p = 0.013) and Aβ positivity (Odds Ratio: 0.59, 95% CI: 0.38, 0.91; p = 0.016), independent of demographics and APOE ɛ4. ROC curves (AUC = 0.73, 95% CI: 0.64, 0.82; p < 0.0001) showed that the optimal threshold for plasma Aβ42/Aβ40 ratio in relation to brain Aβ positivity was 0.060 with a sensitivity of 82.4% and specificity of 62.8%. APOE ɛ4 carriers had lower Aβ42/Aβ40 ratio and a higher Aβ positivity determined with the Aβ42/Aβ40 ratio threshold of 0.060. CONCLUSION Plasma Aβ42/Aβ40 ratio assayed using Simoa is weakly correlated with in vivo brain amyloid and has limited accuracy in screening for amyloid positivity and for studying risk factors of brain amyloid burden when in vivo imaging is not feasible.

Abstract
Pre-pandemic disparities placed Latinos at risk for COVID-19. This report describes the associations between increased viral exposure through social contact and material hardship and the uneven distribution of COVID-19 morbidity among Latino older adults using data from the recently released supplement to the National Social Life, Heath, and Aging Project (NSHAP) (N = 2672), a population-based panel study of adults born 1920-1965. Logistic regression revealed that material hardship and reliance on outside help were significantly correlated with COVID-19 infection, which may partially explain the disproportionate burden Latinos experience during the pandemic.

Sun Exposure Is Associated with Reduced Breast Cancer Risk among Women Living in the Caribbean: The Atabey Study in Puerto Rico. Cancer Epidemiol Biomarkers Prev 2022; 31:430-435. [PMID: 34810207 PMCID: PMC9190767 DOI: 10.1158/1055-9965.epi-21-0932] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2021] [Revised: 10/29/2021] [Accepted: 11/15/2021] [Indexed: 02/03/2023] Open
Abstract
BACKGROUND Though inconsistent, there is evidence that sun exposure is associated with reduced breast cancer risk. Previous studies have been conducted in geographical regions with seasonal variation in UV radiation, including periods of low to no exposure, and among participants mostly of European descent. Puerto Rico has no significant seasonal fluctuation, with continuous exposure to very high UV radiation. METHODS We conducted a population-based case-control study of breast cancer among women in metropolitan San Juan, Puerto Rico, examining a cumulative sun exposure index (SEI) based on a comparison of reflectance of sun-exposed and non-exposed skin. A chromameter was used to measure skin reflectance and estimate the difference between constitutive (unexposed) and facultative (exposed) skin pigmentation in 307 cases and 328 controls. Breast cancer risk factors were ascertained with interviewer-administered questionnaires. OR and 95% confidence intervals (CI) were estimated with unconditional logistic regression. RESULTS Adjusted breast cancer odds were lower for the highest tertile of the SEI (ORadj = 0.47; 95% CI, 0.29-0.74). Results were similar within strata of estrogen receptor status. In analyses stratified by constitutive skin pigmentation, among participants with darker skin color, breast cancer risk was lower with more sun exposure (ORadj = 0.33; 95% CI, 0.16-0.70). CONCLUSIONS We found lower risk of breast cancer associated with greater sun exposure in a population living with high, continuous sun exposure. This beneficial finding should be placed in the context of other effects of sun exposure. IMPACT Sun exposure is a modifiable factor that may contribute, directly or indirectly, to lower breast cancer risk.

Oral microbiota and periodontitis severity among Hispanic adults. Front Cell Infect Microbiol 2022; 12:965159. [PMID: 36452304 PMCID: PMC9703052 DOI: 10.3389/fcimb.2022.965159] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Accepted: 10/11/2022] [Indexed: 11/16/2022] Open
Abstract
Background Periodontitis, one of the most common bacterial infections characterized by chronic inflammation, is also known to be a risk factor for chronic conditions, including cardiovascular disease and cancer. This inflammation is driven by an altered microbiota with an increase in pathogenic bacteria. We evaluated the association between oral microbiota and periodontitis severity in high-risk Hispanics. Method This cross-sectional study recruited 134 sexually active participants aged 21 to 49 years old from STI Clinics in Puerto Rico. A periodontal examination, saliva collection, and an interviewer-administered questionnaire were performed. Periodontal severity was categorized as: having no disease, mild, and moderate/severe and BOP and tooth loos was noted. Saliva samples were collected for genomic DNA extraction, downstream 16S rDNA amplification sequencing, and bioinformatics analyses. Results The structure, composition, and diversity of bacterial communities differed significantly according to periodontal severity. The richness and overall diversity also differed between participants without periodontitis and participants with some level of periodontal disease. A higher abundance of Prevotella, Veillonella, or Treponema was attributed to periodontal disease and Aggregatibacter to severe bleeding on probing, while Neisseria was found in higher abundance in healthy participants, decreasing its levels with drinking, smoking, and oral sex practices. Conclusions Our findings indicate that dysbiosis occurs as periodontal disease progresses, and both alcohol consumption and smoking habits pose risk factors for oral dysbiosis. These results are of public health and clinical impact, as several bacteria identified could serve in the future as biomarkers for periodontitis and oral cancer risk.

Abstract
BACKGROUND Studies of cumulative anticholinergic drug burden on cognitive function and impairment are emerging, yet few for Hispanics/Latinos. OBJECTIVE To examine associations between anticholinergic use and neurocognitive performance outcomes among diverse Hispanics/Latinos. METHODS This prospective cohort study included diverse Hispanic/Latino participants, enrolled in the Study of Latinos-Investigation of Neurocognitive, from New York, Chicago, Miami, and San Diego (n = 6,249). Survey linear regression examined associations between anticholinergic use (measured during baseline [Visit 1] and average 7-year follow up [Visit 2]) with global cognition, episodic learning, memory, phonemic fluency, processing speed, executive functioning, and average 7-year change. RESULTS Anticholinergic use was associated with lower cognitive global cognition (β= -0.21; 95% CI [-0.36; -0.05]), learning (β= -0.27; 95% CI [-0.47; -0.07]), memory (β= -0.22; 95% CI [-0.41; -0.03]), and executive functioning (β= -0.22; 95% CI [-0.40; -0.03]) scores, particularly among those who took anticholinergics at both visits. Anticholinergic use was associated with faster decline in global cognition, learning, and verbal fluency (β: -0.28 [95% CI: -0.55, -0.01]; β: -0.28 [95% CI: -0.55, -0.01]; β: -0.25, [95% CI -0.47, -0.04], respectively). Sex modified associations between anticholinergic use with global cognition, learning, and executive functioning (F3 = 3.59, F3 = 2.84, F3 = 3.88, respectively). CONCLUSION Anticholinergic use was associated with lower neurocognitive performance, especially among those who used anticholinergics at both visits, among a study population of diverse Hispanics/Latinos. Findings will support evidence-based decisions regarding anticholinergic prescriptions and efforts to minimize cognitive impact.

Prevalence of self-reported obesity among diverse Latino adult populations in New York City, 2013-2017. Obes Sci Pract 2021; 7:379-391. [PMID: 34401197 PMCID: PMC8346377 DOI: 10.1002/osp4.490] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2020] [Revised: 01/02/2021] [Accepted: 01/24/2021] [Indexed: 11/09/2022] Open
Abstract
INTRODUCTION Latinos in the United States represent a heterogeneous population disproportionally impacted by obesity. Yet, the prevalence of obesity by specific Latino group is unclear. Using the New York City Community Health Survey (2013-2017), this study compared self-reported obesity in the city's largest Latino adult populations (Puerto Ricans, Mexicans, Dominicans, Ecuadorians, and Colombians). METHODS Age-standardized prevalence using the 2000 Census and prevalence ratios (PRs) for self-reported obesity (BMI ≥30 kg/m2) by country of origin were estimated using weighted multivariable logistic regression adjusting for socio-demographic characteristics, health status, and behaviors. RESULTS Obesity prevalence among Mexicans (36.8%; 95% CI [31.5, 42.4]) and Puerto Ricans (36.3%; 95% CI [31.7, 41.3]) was significantly higher than that among Colombians (23.8%; 95% CI [18.8, 29.5]), Ecuadorians (24.2%; 95% CI [20.7, 28.1]), and Dominicans (27.0%; 95% CI [25.0, 29.1]). After adjusting for covariates, compared to Mexicans, the PRs of obesity remained significantly lower for Colombians (PR = 0.80; 95% CI [0.64, 1.00]), Ecuadorians (PR = 0.72; 95% CI [0.61, 0.86]) and Dominicans (PR = 0.75; 95% CI [0.65, 0.85]). There was no significant difference between Mexicans and Puerto Ricans. CONCLUSION Obesity prevalence differs by country of origin, suggesting that clustering of Latinos in public health research may obscure unique risks among specific groups. Despite group differences, all Latino groups exhibit high prevalence of obesity and warrant renewed efforts tailored to the specific context and culture of each group to prevent and reduce obesity.

Abstract
OBJECTIVE This study aimed to estimate the association between cycles of poverty, measured by intergenerational educational attainment (IEA), and the burden of obesity and metabolic dysfunction among Hispanic/Latino individuals in the United States. METHODS This is a cross-sectional study utilizing data from 392 adults linked to 286 biologic parents from the Niños Lifestyle and Diabetes Study and the Sacramento Area Latino Study on Aging. The educational attainment of parents and offspring was dichotomized in order to categorize IEA. Outcomes included obesity and metabolic syndrome (MetS). Model-based standardization with population weights was used to compare obesity and MetS across generations, and Poisson regression was used to estimate prevalence ratios by IEA. RESULTS A higher prevalence of obesity and MetS was observed in offspring (54% and 69%, respectively) compared with their parents (48% and 42%, respectively). Compared with stable-low IEA, any category with high offspring education was associated with lower obesity and MetS prevalence. The upwardly mobile group saw the greatest benefit; they were 38% (95% CI: 10%-57%) and 46% (95% CI: 21%-63%) less likely to have obesity or MetS. CONCLUSIONS IEA strongly patterns cardiometabolic health among Hispanic/Latino individuals living in the United States, suggesting that promotion of higher education is associated with reductions in obesity and MetS, potentially benefitting future generations of this population.

Abstract
Progressive supranuclear palsy (PSP) is a neurodegenerative disease that usually develops after the sixth decade of life, and the diagnosis is purely clinical except in cases of pathologically confirmed autopsies. A multidisciplinary approach to meet the patients' complex needs is the current core treatment strategy for this devastating disorder. No medications can reverse the disease course. In this report, we present a case of PSP that developed after the sixth decade of life and where the diagnosis was supported by clinical and neuroimaging data. Despite the fact that PSP is a rapidly progressive neurodegenerative disorder and no effective treatments are currently available, our case illustrates the clinically significant improvement in cognition and function achieved in a patient with a treatment involving a combination of antidepressant medications and rivastigmine.

Abstract
Background: Evidence indicates escalating rates of cigarette use among foreign-born Latinx as their time in the U.S increases. As such, it's important to understand shifts in pre- to post-immigration smoking patterns early in the immigration process and its associated factors.Objectives: To examine 1) cigarette use among recent Latinx immigrants (RLIs) during their initial year in the U.S.; 2) whether cigarette use after immigration is influenced by smoking patterns in immigrant's country of origin; and 3) associations between pre/post immigration sociocultural factors and changes in cigarette use after immigration.Methods: Baseline data were utilized from an on-going longitudinal study of 540 young adult (50% females) RLIs. Inclusion criteria was being between ages 18 and 34, residing in Miami-Dade County, Florida, and having immigrated from a Latin American country within the past yearResults: Approximately 31% of participants reported being smokers in their country of origin while 26% were current smokers (while residing in the U.S). Post-immigration cigarette use was substantially influenced by country of origin cigarette use (V = .68); 84% of pre-immigration smokers reported no change in smoking frequency, while 11% lowered and 6% increased their cigarette use post-immigration. Reduction in smoking after immigration was more likely among participants with higher pre-immigration social support (aOR = 1.87) and less likely among those residing in high-crime neighborhoods (aOR = .84).Conclusion: Interventions aimed to discourage cigarette use should begin early in the immigration process and account for RLIs' pre-immigration smoking patterns. Interpersonal supports and neighborhood contextual factors should be considered when developing smoking cessation programs with this population.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is the fastest growing cancer in the United States. Studies have shown that compared to Blacks and non-Hispanic Whites, Hispanics have a higher HCC incidence and mortality rate. Most studies investigating HCC in Hispanics have been conducted utilizing data largely from the Western and Southern United States. These findings may, however, not be highly representative of Hispanics in the Northeast, given the nonhomogenous distribution and diversity of Hispanics across the United States. METHODS Some 148 HCC patients diagnosed between 1996 and 2012 were identified from a tertiary center in the northeastern United States. Hispanic patients were randomly matched to non-Hispanic White patients by year of diagnosis. Patient characteristics, HCC risk factors, treatment, and outcome were recorded. A Kaplan-Meier (KM) plot with log-rank tests was used for survival analysis. RESULTS Compared to non-Hispanic White patients (n=89), Hispanic HCC patients (n=59) were more likely to have chronic hepatitis C infection (69.5% vs. 38.2%, p < 0.01), alcoholic liver disease (37.3% vs. 21.4%, p = 0.04) and were less likely to have chronic hepatitis B infection (6.8% vs. 24.7%, p = 0.01), and private insurance (37.3% vs. 57.3%, p = 0.02). Hispanics were more likely to be diagnosed with an earlier stage disease (Barcelona Clinic Liver Cancer, BCLC stages A and B) compared to non-Hispanic patients (71.7% vs. 36.8%, p < 0.01) and were more likely to receive locoregional treatment. Although Hispanics trended towards improved overall survival, this finding did not hold when stratified by the BCLC stage. CONCLUSION Risk factors for HCC in the northeastern Hispanic population are like those found among Hispanics in other US regions. Other research suggests Hispanics are at increased risk for hepatic injury and HCC. However, HCC in this northeastern Hispanic population appears to be less aggressive (earlier stage and trend towards better overall survival) than non-Hispanics. Further research may be needed to identify potential differences by ethnic group for HCC risk factors, presentation, and outcomes.

Abstract
The incidence of inflammatory bowel disease (IBD) is on the rise in Latin America. The aims of this study were to examine epidemiologic trends of IBD in Colombia by demographics, region, urbanicity, and to describe the IBD phenotype in a large well-characterized Colombian cohort.We used a national database of 33 million adults encompassing 97.6% of the Colombian population in order to obtain epidemiologic trends of IBD using International Classification of Diseases 10codes for adults with ulcerative colitis (UC) and Crohn disease (CD). We calculated the incidence and prevalence of UC and CD from 2010-2017 and examined epidemiologic trends by urbanicity, demographics, and region. We then examined the IBD phenotype (using Montreal Classification), prevalence of IBD-related surgeries, and types of IBD-medications prescribed to adult patients attending a regional IBD clinic in Medellin, Colombia between 2001 and 2017.The incidence of UC increased from 5.59/100,000 in 2010 to 6.3/100,000 in 2017 (relative risk [RR] 1.12, confidence interval (CI) (1.09-1.18), P < .0001). While CD incidence did not increase, the prevalence increased within this period. The Andes region had the highest incidence of IBD (5.56/100,000 in 2017). IBD was seen less in rural regions in Colombia (RR=.95, CI (0.92-0.97), p < .01). An increased risk of IBD was present in women, even after adjusting for age and diagnosis year (RR 1.06 (1.02-1.08), P = .0003). The highest IBD risk occurred in patients 40 to 59 years of age. In the clinic cohort, there were 649 IBD patients: 73.7% UC and 24.5% CD. Mean age of diagnosis in CD was 41.0 years and 39.9 years in UC. UC patients developed mostly pancolitis (43%). CD patients developed mostly ileocolonic disease and greater than a third of patients had an inflammatory, non-fistulizing phenotype (37.7%). A total of 16.7% of CD patients had perianal disease. CD patients received more biologics than UC patients (odds ratio: 3.20, 95% CI 2.19-4.69 P < .001).Using both a national representative sample and a regional clinic cohort, we find that UC is more common in Colombia and is on the rise in urban regions; especially occurring in an older age cohort when compared to Western countries. Future studies are warranted to understand evolving environmental factors explaining this rise.

Early life gut microbiota is associated with rapid infant growth in Hispanics from Southern California. Gut Microbes 2021; 13:1961203. [PMID: 34424832 PMCID: PMC8386720 DOI: 10.1080/19490976.2021.1961203] [Citation(s) in RCA: 29] [Impact Index Per Article: 9.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2021] [Revised: 07/06/2021] [Accepted: 07/20/2021] [Indexed: 02/04/2023] Open
Abstract
We aimed to determine if the newborn gut microbiota is an underlying determinant of early life growth trajectories. 132 Hispanic infants were recruited at 1-month postpartum. The infant gut microbiome was characterized using 16S rRNA amplicon sequencing. Rapid infant growth was defined as a weight-for-age z-score (WAZ) change greater than 0.67 between birth and 12-months of age. Measures of infant growth included change in WAZ, weight-for-length z-score (WLZ), and body mass index (BMI) z-scores from birth to 12-months and infant anthropometrics at 12-months (weight, skinfold thickness). Of the 132 infants, 40% had rapid growth in the first year of life. Multiple metrics of alpha-diversity predicted rapid infant growth, including a higher Shannon diversity (OR = 1.83; 95% CI: 1.07-3.29; p = .03), Faith's phylogenic diversity (OR = 1.41, 95% CI: 1.05-1.94; p = .03), and richness (OR = 1.04, 95% CI: 1.01-1.08; p = .02). Many of these alpha-diversity metrics were also positively associated with increases in WAZ, WLZ, and BMI z-scores from birth to 12-months (pall<0.05). Importantly, we identified subsets of microbial consortia whose abundance were correlated with these same measures of infant growth. We also found that rapid growers were enriched in multiple taxa belonging to genera such as Acinetobacter, Collinsella, Enterococcus, Neisseria, and Parabacteroides. Moreover, measures of the newborn gut microbiota explained up to an additional 5% of the variance in rapid growth beyond known clinical predictors (R2 = 0.37 vs. 0.32, p < .01). These findings indicate that a more mature gut microbiota, characterized by increased alpha-diversity, at as early as 1-month of age, may influence infant growth trajectories in the first year of life.

Abstract
BACKGROUND Hispanics/Latinos in the United States are more likely to live in neighborhoods with greater exposure to air pollution and are projected to have the largest increase in dementia among race/ethnic minority groups. OBJECTIVE We examined the associations of air pollution with performance on cognitive function tests in Hispanic/Latino adults. METHODS We used data from the San Diego site of the Hispanic Community Health Study/Study of Latinos, an ongoing cohort of Hispanics/Latinos. This analysis focused on individuals ≥45 years of age who completed a neurocognitive battery examining overall mental status, verbal learning, memory, verbal fluency, and executive function (n = 2,089). Air pollution (PM2.5 and O3) before study baseline was assigned to participants' zip code. Logistic and linear regression were used to estimate the associations of air pollution on overall mental status and domain-specific standardized test scores. Models accounted for complex survey design, demographic, and socioeconomic characteristics. RESULTS We found that for every 10μg/m3 increase in PM2.5, verbal fluency worsened (β: -0.21 [95%CI: -0.68, 0.25]). For every 10 ppb increase in O3, verbal fluency and executive function worsened (β: -0.19 [95%CI: -0.34, -0.03]; β: -0.01 [95%CI: -0.01, 0.09], respectively). We did not identify any detrimental effect of pollutants on other domains. CONCLUSION Although we found suggestions that air pollution may impact verbal fluency and executive function, we observed no consistent or precise evidence to suggest an adverse impact of air pollution on cognitive level among this cohort of Hispanic/Latino adults.

Abstract
BACKGROUND Emerging adulthood (ages 18-26) is a time of identity exploration, experimentation, focusing on self or others, and instability, themes captured in the Inventory of Dimensions of Emerging Adulthood (IDEA). Preliminary evidence suggests that emerging adults (EAs) with a history of adverse childhood experiences (ACE) score differently on transition dimensions than their peers, however, the role of ACE in the IDEA-substance use relationship is unknown. METHOD Data are from a longitudinal study of acculturation and health among Hispanics in California (N = 1,065). Multivariable regression models assessed the association between IDEA and ACE (no ACE, 1-3 ACE, and ≥ 4 ACE) for substance use behaviors over 2 time points. Interaction terms assessed whether ACE moderated the association between subjective perceptions of IDEA at age 20 and substance use at age 24. RESULTS ACE-exposed EAs scored higher on identity exploration, instability, self-focus, and experimentation dimensions than their peers (ps < .01-.001). Scores on experimentation, identity exploration, and self-focus at age 20 were associated with divergent patterns of substance use across ACE exposure categories. In comparison to other groups, individuals in ≥ 4 ACE group who strongly identified with these transition themes at age 20 had the highest probability of binge drinking, past 30-day alcohol, marijuana, and illicit drug use at age 24 (adjusted odds ratios = 1.09-1.49, confidence interval [1.02-2.58]). CONCLUSION Our findings suggest that ACE can affect subjective perceptions of transition themes and increased risk for substance use over time. Implications for substance use prevention efforts tailored to Hispanic EAs are discussed. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

[PMID: 29347825 DOI: 10.1080/13557858.2018.1427704] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/17/2017] [Accepted: 12/18/2017] [Indexed: 06/07/2023]
Abstract
Objectives: This paper investigates a community-based intervention for young fathers, FatherWorks, compared to care-as-usual, 24/7 Dads. We hypothesized that utilizing the FatherWorks intervention (a 15 session parenting intervention, 13 session employment class, paid internship, case management, and access to behavioral health services) will assist in readiness to use condoms and increase condom usage, which may differ by race/ethnicity.Methods: Eligible males (n = 328) were enrolled into a Randomized Control Trial. Participants were 15-24 years old and had fathered one or more children with a female under the age of 21. A survey was taken at baseline and at 15 weeks following the intervention.Results: Analyses of changes indicated that intervention participants improved from the pre-contemplation stage of condom usage towards contemplation, and from preparation to action. The pattern of improvement in the condom use stage of change was different in African-American versus Hispanic participants. Changes in condom use during last intercourse were not significant.Conclusions: Study findings indicate that FatherWorks is successful in increasing the intent to use condoms, with the effect manifesting differently in African-American and Hispanic young fathers. Future work with minority fathers indicates a need for cultural adaptation of the intervention.

Abstract
BACKGROUND Among older adults, poorer cognitive functioning has been associated with impairments in instrumental activities of daily living (IADLs). However, IADL impairments among older Hispanics/Latinos is poorly understood. OBJECTIVE To characterize the relationships between cognition and risk for IADL impairment among diverse Hispanics/Latinos. METHODS Participants included 6,292 community-dwelling adults from the Study of Latinos - Investigation of Neurocognitive Aging, an ancillary study of 45+ year-olds in the Hispanic Community Health Study/Study of Latinos. Cognitive data (learning, memory, executive functioning, processing speed, and a Global cognitive composite) were collected at Visit 1. IADL functioning was self-reported 7 years later, and treated as a categorical (i.e., risk) and continuous (i.e., degree) measures of impairment. Survey two-part models (mixture of logit and generalized linear model with Gaussian distribution) and ordered logistic regression tested the associations of cognitive performance (individual tests and composite z-score) with IADL impairment. Additionally, we investigated the moderating role of age, sex, and Hispanic/Latino background on the association between cognition and IADL impairment. RESULTS Across all cognitive measures, poorer performance was associated with higher odds of IADL impairment 7 years later. Associations were generally stronger for the oldest group (70+ years) relative to the youngest group (50-59 years). Sex and Hispanic/Latino background did not modify the associations. Across the full sample, lower scores on learning, memory, and the Global cognitive composite were also associated with higher degree of IADL impairment. CONCLUSION Across diverse Hispanics/Latinos, cognitive health is an important predictor of everyday functioning 7 years later, especially in older adulthood.

Abstract
OBJECTIVE Improvement in health-related quality of life (HRQoL) is a public health goal of Healthy People 2020. Hispanics living in the United States are at risk for poor HRQoL, but the causes and correlates of this risk are not well understood. Thus, the present study examined individual-level psychosocial and neighborhood-level built environment correlates of physical and mental HRQoL among Hispanic adults. METHOD A community sample of Hispanic adults (N = 383) completed self-report health-related questionnaires, and census tract was used to collect data on neighborhood-level built environment variables. Multilevel modeling was used to examine individual-level psychosocial (language preference, religiosity, subjective social status, discrimination, and number of years lived in the United States) and neighborhood-level built-environment (the retail food environment, proximity to alcohol retailers, and tobacco retailer density) correlates of physical and mental HRQoL. RESULTS Higher subjective social status was significantly associated with better HRQoL, and more experiences with discrimination were significantly associated with lower HRQoL. For physical HRQoL, these relationships were stronger in neighborhoods with a higher density of tobacco retail outlets. CONCLUSIONS Findings from this study suggest that subjective social status and discrimination play important roles in HRQoL among Hispanics, in particular in neighborhoods with a higher density of tobacco retail outlets. This study highlights the importance of considering neighborhood context, and in particular neighborhood disadvantage, when examining the relationship between social status, discrimination and HRQoL among Hispanics.

Abstract
Introduction Hispanics are the largest ethnic minority group in the United States. The prevalence of depression and co-morbid depression in the Hispanic population is well-recognized. The positive association between physical activity and psychological health improves mood, emotional well-being, and prognostic outcome. Objectives There are two aspects of our research paper. First, it critically reviews the available literature showing the correlation between physical exercise and depression. Second, it analyzes the association between exercise and depression in uncontrolled diabetic Hispanics using data collected from the local community intervention program. Method A chi-square analysis was conducted to examine whether levels of physical activity reported at the baseline were associated with the frequency of depressed mood and anhedonia self-reported for the previous two weeks. This study utilized the use of the PHQ-2 scale for the assessment of depressive symptoms. The PHQ-2 scale is a useful tool to screen for depression in the integrated care setting. Participants from a local community intervention program were stratified on the basis of their gender and preferred language. Data were collected and represented in tables according to demographic characteristics. Results Our study established a statistically significant association between the levels of physical activity and the frequency of depression symptoms among Spanish speaking participants from the local community intervention program. These results provide convincing evidence that biological, developmental, social, and psychological factors facilitate the association between physical activity and depression.

Ethnicity, educational attainment, and physical health of older adults in the United States. Aging Med (Milton) 2019; 2:104-111. [PMID: 31608316 PMCID: PMC6788632 DOI: 10.1002/agm2.12050] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2018] [Revised: 12/29/2018] [Accepted: 01/01/2019] [Indexed: 01/15/2023] Open
Abstract
OBJECTIVE Minorities' diminished returns theory suggests that socioeconomic status (SES) resources generate fewer health benefits for racial and ethnic minority groups, compared to the majority group. The current study aimed to compare Hispanic and non-Hispanic white older adults for the association between educational attainment and poor physical self-rated health (SRH). METHODS The first wave of the University of Michigan National Poll on Healthy Aging (UM-NPHA) included 1820 older adults who were 50-80 years old and were either non-Hispanic white (n = 1618) or Hispanic white (n = 202). The main independent variable of interest was educational attainment. The main dependent variable of interest was poor physical SRH. Gender, age, marital status, and employment status were covariates. Ethnicity was the focal effect modifier. RESULTS Overall, higher level of educational attainment was associated with better physical SRH. A significant interaction was found between ethnicity and level of educational attainment, which was indicative of a smaller physical SRH gain due to high educational attainment for Hispanic white compared to non-Hispanic white older adults. In ethnic-specific models, we found evidence suggesting that high educational attainment reduced the odds of poor physical SRH for non-Hispanic whites but not for Hispanic whites. CONCLUSION Compared to non-Hispanic whites, Hispanic whites gain less physical SRH benefits from their educational attainment.

Influence of Sleep Duration on Postpartum Weight Change in Black and Hispanic Women. Obesity (Silver Spring) 2019; 27:295-303. [PMID: 30597751 PMCID: PMC6345591 DOI: 10.1002/oby.22364] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/07/2018] [Accepted: 10/14/2018] [Indexed: 01/19/2023]
Abstract
OBJECTIVE The primary purpose of this study was to examine associations of objectively measured sleep duration with weight changes in black and Hispanic mothers over the first postpartum year. METHODS Data were from 159 mothers (69% black, 32% Hispanic). Nocturnal sleep duration was assessed using wrist actigraphy at 6 weeks and 5 months post partum, examined as a continuous variable and in categories (< 7 vs. ≥ 7 hours/night, consistent with American Academy of Sleep Medicine recommendations). Body weights were abstracted from medical records in pregnancy and measured at 6 weeks, 5 months, and 12 months post partum. Outcomes included early postpartum (6 weeks to 5 months) and late postpartum (5 to 12 months) weight changes. RESULTS The majority of participants slept < 7 hours/night at 6 weeks (75%) and 5 months (63%) post partum. Early postpartum weight change did not differ by 6-week sleep duration category. By contrast, adjusted average late postpartum weight gain (SE) was 1.8 (0.7) kg higher in participants sleeping < 7 hours/night at 5 months post partum compared with those sleeping ≥ 7 hours/night (P = 0.02). Results did not show statistically significant associations of continuous measures of sleep duration, nor of measures of sleep quality, with postpartum weight changes. CONCLUSIONS Sleeping < 7 hours/night was associated with late postpartum weight gain in minority mothers.

Abstract
This randomized controlled trial tested the efficacy of a Web-based intervention to increase sexual communication between parents and adolescents. Parent/adolescent dyads (n = 660) were recruited from communities in the San Juan area and randomly assigned to the Cuídalos sexual communication or physical activity program. Parent assessments were obtained preintervention and at 3-, 6-, and 12-month follow-up. Parents in the experimental group reported significantly more sexual communication (ie, peer pressure, sexual prevention, protection, risk) over time than parents in the control group. Results support the efficacy of the Cuídalos Web-based format and provide insight into future Web-based sexual health interventions for this population.

Abstract
Molecular subtypes of triple negative breast cancer (TNBC) are associated with variation in survival and may assist in treatment selection. However, the association of patient race or ethnicity with subtypes of TNBC and clinical outcome has not been addressed. Using nCounter Gene Expression Codesets, we classified TNBCs into subtypes: basal-like immune-activated (BLIA), basal-like immunosuppressed (BLIS), luminal androgen receptor (LAR), and mesenchymal (MES) in 48 Hispanic, 12 African-American, 21 Asian, and 34 White patients. Mean age at diagnosis was significantly associated with subtype, with the youngest mean age (50 years) in MES and the oldest mean age (64 years) in LAR (p < 0.0005). Subtype was significantly associated with tumor grade (p = 0.0012) and positive lymph nodes (p = 0.021), with a marginally significant association of tumor stage (p = 0.076). In multivariate Cox-proportional hazards modeling, BLIS was associated with worst survival and LAR with best survival. Hispanics had a significantly higher proportion of BLIS (53%, p = 0.03), whereas Asians had a lower proportion of BLIS (19%, p = 0.05) and a higher proportion of LAR (38%, p = 0.06) compared to the average proportion across all groups. These differences in proportions of subtype across racial and ethnic groups may explain differences in their outcomes. Determining subtypes of TNBC facilitates understanding of the heterogeneity of the TNBCs and provides a foundation for developing subtype-specific therapies and better predictors of TNBC prognosis for all races and ethnicities.

Abstract
OBJECTIVE Subjective social status (SSS), perceived rank in the social ladder, is associated with weight, but determinants of SSS in youth remain unknown. Relationships between youth SSS and income, food insecurity, parent SSS, and BMI change were investigated during an obesity intervention. METHODS Data came from a family-centered, community-based obesity intervention for low-income families. Parent and youth SSS were assessed using a validated, age-appropriate SSS scale. Food insecurity and socioeconomic factors were assessed in parents; child and parent weight-related data were measured at baseline and post intervention. RESULTS Participants included 110 primarily Hispanic (97%) low-income youth and their parents. Food insecurity was reported in 66.4% of families. Youth SSS was positively associated with parent SSS (P = 0.0014). In both parents and children, the association between income and SSS was moderated by food insecurity such that lower income was more strongly associated with lower SSS among food-insecure households (P = 0.0286 and P = 0.0327, respectively). Youth SSS was not associated with youth BMI reduction. CONCLUSIONS Youth SSS was not predictive of weight loss in this intervention. Intriguingly, the association between income and SSS was modified by food insecurity, suggesting that food insecurity shapes the contribution of socioeconomic factors to one's perceived social status.

Abstract
INTRODUCTION While individuals live with dementia for many years, utilization and expenditures from disease onset through the end-of-life period have not been examined in ethnically diverse samples. METHODS We used a multiethnic, population-based, prospective study of cognitive aging (Washington Heights-Inwood Columbia Aging Project) linked to Medicare claims to examine total Medicare expenditures and health care utilization among individuals with clinically diagnosed incident dementia from disease onset to death. RESULTS High-intensity treatment (hospitalizations, life-sustaining procedures) was common and mean Medicare expenditures per year after diagnosis was $69,000. Non-Hispanic blacks exhibited higher spending relative to Hispanics and non-Hispanic whites 1 year after diagnosis. Non-Hispanic blacks had higher total (mean=$205,000) Medicare expenditures from diagnosis to death compared with non-Hispanic whites (mean=$118,000). Hispanics' total expenditures and utilization after diagnosis was similar to non-Hispanic whites despite living longer with dementia. DISCUSSION Health care spending for patients with dementia after diagnosis through the end-of-life is high and varies by ethnicity.

It Weigh(t)s on You: Everyday Discrimination and Adiposity Among Latinos. Obesity (Silver Spring) 2018; 26:1474-1480. [PMID: 30175908 PMCID: PMC6159926 DOI: 10.1002/oby.22248] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2016] [Revised: 08/22/2016] [Accepted: 10/31/2016] [Indexed: 12/16/2022]
Abstract
OBJECTIVE Evidence suggests discrimination increases the risk of obesity. The biopsychosocial model of racism posits that psychological factors such as depressive symptoms may link experiences of perceived interpersonal discrimination to obesity. This study tested whether self-reported experiences of everyday discrimination were associated with adiposity indicators and whether depressive symptoms explained these associations. METHODS Cross-sectional survey data of 602 Latino adults living in Lawrence, Massachusetts, from the Latino Health and Well-being Project (2011-2013) were used. Participants completed questionnaires assessing perceived everyday discrimination and depressive symptoms. Anthropometric measures (i.e., BMI and waist circumference [WC]) were obtained by trained staff. Structural equation modeling was employed to test for direct and indirect effects of perceived everyday discrimination on adiposity. RESULTS Perceived everyday discrimination was directly and positively associated with higher BMI and WC, independent of sociodemographic factors, physical activity, and stressful life events. Perceived everyday discrimination was not indirectly associated with BMI and WC through depressive symptoms. However, perceived everyday discrimination was associated with higher levels of depressive symptoms. CONCLUSIONS Self-reported everyday discrimination among Latino adults is associated with adiposity. Day-to-day interpersonal discrimination may be implicated in obesity disparities for Latino adults.

Abstract
AIM We investigated the cross-sectional association between diet quality and severe periodontitis in a sample of diverse Hispanics from the Hispanic Community Health Study/Study of Latinos. MATERIALS AND METHODS A total of 13,920 Hispanic/Latinos aged 18-74 years of different heritages underwent a full-mouth oral examination and completed two 24-hr dietary recalls during 2008-2011. Severe periodontitis was defined as having ≥30% tooth sites with clinical attachment loss ≥5 mm. Diet quality was assessed using the Alternative Healthy Eating Index (AHEI-2010). We evaluated the association of diet quality with severe periodontitis adjusting for age, sex, nativity status, income, education, last dental visit, current insurance, cigarette smoking, diabetes, and energy intake. RESULTS Relative to those at the lowest quartile of diet quality, individuals at the highest quartile had significantly lower odds of severe periodontitis (adjusted OR = 0.57, 95% CI: 0.39-0.82), with evidence of a dose-response relationship across AHEI quartiles. Among AHEI-2010 components, higher consumption of whole grains and fruits, and lower consumption of red/processed meats were associated with lower odds of severe periodontitis. CONCLUSION Better-quality diet was associated with lower prevalence of severe periodontitis although the causal pathways need to be clarified in future work.

Abstract
OBJECTIVE The objective of this study was to evaluate cross-sectional associations of sodium and potassium with BMI, waist circumference (WC), and body fat and to determine whether the nativity and/or duration of United States (US) residence modified these associations. METHODS Sodium and potassium were derived from 24-hour diet recalls from 16,156 US participants of the 2008 to 2011 Hispanic Community Health Study/Study of Latinos (HCHS/SOL) and from 24-hour urine in 447 HCHS/SOL participants. BMI, WC, and body fat were measured. RESULTS Dietary sodium that was 500 mg/d higher was cross-sectionally associated with a 0.07-kg/m2 higher BMI (P < 0.05) and a 0.18-cm larger WC (P = 0.04). Dietary potassium that was 500 mg/d higher was only associated with lower BMI and smaller WC among those who were foreign-born with 10 + years in the US (-0.13 kg/m2 , P < 0.01 and -0.36 cm, P = 0.01, respectively) and among those who were US-born (-0.62 kg/m2 , P < 0.01 and -1.42 cm, P < 0.01, respectively). Urinary sodium that was 500 mg/d higher was associated with a 0.27-kg/m2 higher BMI (P < 0.01) and 0.54 kg more body fat (P < 0.01). CONCLUSIONS Sodium intake was associated with higher BMI, WC, and body fat. Potassium intake was associated with lower BMI and smaller WC among US-born participants and participants with a longer duration of US residence.

Abstract
OBJECTIVE This study aimed to explore the genetic mechanisms of regional fat deposition, which is a strong risk factor for metabolic diseases beyond total adiposity. METHODS A genome-wide association study of 7,757,139 single-nucleotide polymorphisms (SNPs) in 983 Mexican Americans (nmale = 403; nfemale = 580) from the Insulin Resistance Atherosclerosis Family Study was performed. Association analyses were performed with and without sex stratification for subcutaneous adipose tissue, visceral adipose tissue (VAT), and visceral-subcutaneous ratio (VSR) obtained from computed tomography. RESULTS The strongest signal identified was SNP rs2185405 (minor allele frequencies [MAF] = 40%; PVAT = 1.98 × 10-8 ) with VAT. It is an intronic variant of the GLIS family zinc finger 3 gene (GLIS3). In addition, SNP rs12657394 (MAF = 19%) was associated with VAT in males (Pmale = 2.39×10-8 ; Pfemale = 2.5 × 10-3 ). It is located intronically in the serum response factor binding protein 1 gene (SRFBP1). On average, male carriers of the variant had 24.6 cm2 increased VAT compared with noncarriers. Subsequently, genome-wide SNP-sex interaction analysis was performed. SNP rs10913233 (MAF = 14%; Pint = 3.07 × 10-8 ) in PAPPA2 and rs10923724 (MAF = 38%; Pint = 2.89 × 10-8 ) upstream of TBX15 were strongly associated with the interaction effect for VSR. CONCLUSIONS Six loci were identified with genome-wide significant associations with fat deposition and interactive effects. These results provided genetic evidence for a differential basis of fat deposition between genders.

Abstract
OBJECTIVE We assessed the hypothesis that metabolic syndrome is associated with adverse changes in cardiac structure and function in participants of the Echocardiographic Study of Latinos (Echo-SOL). METHODS Non-diabetic Echo-SOL participants were included in this cross-sectional analysis. Metabolic syndrome was defined according to the American Heart Association/National Heart, Lung, and Blood Institute 2009 Joint Scientific Statement. Survey multivariable linear regression analyses using sampling weights were used adjusting for multiple potential confounding variables. Additional analysis was stratified according to the presence/absence of obesity (body mass index (BMI) ≥25 kg/m2) and the presence/absence of metabolic syndrome. RESULTS Within Echo-SOL, 1260 individuals met inclusion criteria (59% female; mean age 55.2 years). Compared with individuals without metabolic syndrome, those with metabolic syndrome had lower medial and lateral E' velocities (-0.4 cm/s, (SE 0.1), p=0.0002; -0.5 cm/s (0.2), p=0.02, respectively), greater E/E' (0.5(0.2), p=0.01) and worse two-chamber left ventricular longitudinal strain (0.9%(0.3), p=0.009), after adjusting for potential confounding variables. Increased left ventricular mass index (9.8 g/m2 (1.9), p<0.0001 and 7.5 g/m2 (1.7), p<0.0001), left ventricular end-diastolic volume (11.1 mL (3.0), p=0.0003 and 13.3 mL (2.7), p<0.0001), left ventricular end-systolic volume (5.0 mL (1.4), p=0.0004 and 5.7 mL (1.3) p<0.0001) and left ventricular stroke volume (10.2 mL (1.8), p<0.0001 and 13.0 mL (2.0), p<0.0001) were observed in obese individuals with and without metabolic syndrome compared with individuals with normal weight without metabolic syndrome. In sensitivity analyses, individuals with normal weight (BMI <25 kg/m2) and metabolic syndrome had worse left ventricular global longitudinal strain (2.1%(0.7), p=0.002) and reduced left ventricular ejection fraction (-3.5%(1.4), p=0.007) compared with normal-weight individuals without metabolic syndrome. CONCLUSIONS In a sample of US Hispanics/Latinos metabolic syndrome was associated with worse left ventricular systolic and diastolic function. Adverse changes in left ventricular size and function were observed in obese individuals with and without metabolic syndrome but decreased left ventricular function was also present in normal-weight individuals with metabolic syndrome.

Trends in colorectal cancer mortality in hispanics: a SEER analysis. Oncotarget 2017; 8:108771-108777. [PMID: 29312566 PMCID: PMC5752479 DOI: 10.18632/oncotarget.21938] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2016] [Accepted: 07/23/2017] [Indexed: 02/07/2023] Open
Abstract
Background Colorectal cancer (CRC) mortality among Hispanics is lower than Non-Hispanic Whites (NHW). If Hispanics receive equitable care and achieve the same degree of health benefit, their trend of better survival should be maintained. This study assesses mortality trends among Hispanics overtime to compare their survival improvement with NHW. Methods We used the Incidence-Based Mortality database of the Surveillance, Epidemiology, and End Results Program (SEER) to assess the mortality gap, which is defined as the difference in stage-specific mortality between NHWs and Hispanics, and currently has an advantage for Hispanics. Results There is a statistically significant disparity in stage-specific mortality of CRC by race, with a higher proportion of deaths from metastatic disease among Hispanics than NHW (48% vs. 44% respectively). Comparing the time intervals of 2000-2005 and 2006-2011, mortality was reduced by 15.1% for NHWs and 5.9% for Hispanics, resulting in a narrowing of the mortality gap. The mortality gap between Hispanics and NHW is tapering overtime for every stage of the disease, reflecting that Hispanics have a disparity in CRC mortality. Conclusion The mortality gap between Hispanics and NHWs is narrowing, supporting a significantly lower rate of mortality improvement in Hispanics. If the current trend continues, mortality rates in Hispanics will outpace that of NHWs.

Abstract
OBJECTIVE Adiponectin is found in human serum in three groups of multimers (high molecular weight [HMW], medium molecular weight [MMW], and low molecular weight [LMW]). Two ethnic-specific variants in ADIPOQ, G45R (Hispanic-Americans) and R55C (African-Americans), were previously reported. Although carriers of both variants had mean adiponectin levels ≤ 20% of those of noncarriers, they were not clinically different from noncarriers. To compare carriers of both variants and noncarriers, relative quantification of adiponectin isoforms to total adiponectin was performed on serum samples. METHODS The multimeric patterns of serum adiponectin in G45R carriers (n = 23), R55C carriers (n = 3), and Hispanic- and African-American noncarriers (n = 84 and 44, respectively) from the Insulin Resistance Atherosclerosis Family Study were explored using native Western blotting and densitometry. RESULTS Serum samples from carriers showed an absence of the HMW isoform and a marked reduction in the MMW isoform but an approximate twofold increase in the amount of the LMW isoform. Thus, individuals making only LMW adiponectin are metabolically normal. CONCLUSIONS The results contrast with the proposed biological importance of the HMW multimer. This suggests that the LMW isoform may functionally compensate for some of the loss or reduction of the higher-order multimers in carriers of the G45R and R55C mutations.

Exome sequencing reveals novel genetic loci influencing obesity-related traits in Hispanic children. Obesity (Silver Spring) 2017; 25:1270-1276. [PMID: 28508493 PMCID: PMC5687071 DOI: 10.1002/oby.21869] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2017] [Revised: 03/28/2017] [Accepted: 03/30/2017] [Indexed: 01/01/2023]
Abstract
OBJECTIVE To perform whole exome sequencing in 928 Hispanic children and identify variants and genes associated with childhood obesity. METHODS Single-nucleotide variants (SNVs) were identified from Illumina whole exome sequencing data using integrated read mapping, variant calling, and an annotation pipeline (Mercury). Association analyses of 74 obesity-related traits and exonic variants were performed using SeqMeta software. Rare autosomal variants were analyzed using gene-based association analyses, and common autosomal variants were analyzed at the SNV level. RESULTS (1) Rare exonic variants in 10 genes and 16 common SNVs in 11 genes that were associated with obesity traits in a cohort of Hispanic children were identified, (2) novel rare variants in peroxisome biogenesis factor 1 (PEX1) associated with several obesity traits (weight, weight z score, BMI, BMI z score, waist circumference, fat mass, trunk fat mass) were discovered, and (3) previously reported SNVs associated with childhood obesity were replicated. CONCLUSIONS Convergence of whole exome sequencing, a family-based design, and extensive phenotyping discovered novel rare and common variants associated with childhood obesity. Linking PEX1 to obesity phenotypes poses a novel mechanism of peroxisomal biogenesis and metabolism underlying the development of childhood obesity.

Randomized controlled trial of an early child obesity prevention intervention: Impacts on infant tummy time. Obesity (Silver Spring) 2017; 25:920-927. [PMID: 28332324 PMCID: PMC5404992 DOI: 10.1002/oby.21779] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2016] [Revised: 12/01/2016] [Accepted: 12/31/2016] [Indexed: 12/26/2022]
Abstract
OBJECTIVE To describe infant activity at 3 months old and to test the efficacy of a primary care-based child obesity prevention intervention on promoting infant activity in low-income Hispanic families. METHODS This study was a randomized controlled trial (n = 533) comparing a control group of mother-infant dyads receiving standard prenatal and pediatric primary care with an intervention group receiving "Starting Early," with individual nutrition counseling and nutrition and parenting support groups coordinated with prenatal and pediatric visits. Outcomes included infant activity (tummy time, unrestrained floor time, time in movement-restricting devices). Health literacy was assessed using the Newest Vital Sign. RESULTS Four hundred fifty-six mothers completed 3-month assessments. Infant activity results were: 82.6% ever practiced tummy time; 32.0% practiced tummy time on the floor; 34.4% reported unrestrained floor time; 56.4% reported ≥1 h/d in movement-restricting devices. Inadequate health literacy was associated with reduced tummy time and unrestrained floor time. The intervention group reported more floor tummy time (OR 2.16, 95% CI 1.44-3.23) and unrestrained floor time (OR 1.69, 95% CI 1.14-2.49) compared to controls. No difference in the time spent in movement-restricting devices was found. CONCLUSIONS Tummy time and unrestrained floor time were low. Primary care-based obesity prevention programs have potential to promote these activities.

Ageing out of place: The meaning of home among hispanic older persons living in the United States. Int J Older People Nurs 2017; 12. [PMID: 28393460 DOI: 10.1111/opn.12150] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2016] [Accepted: 02/14/2017] [Indexed: 11/30/2022]
Abstract
AIM To explore the meaning of home among older Hispanic immigrants who are "aging out of place." BACKGROUND Emerging evidence supports the concept of older persons ageing in place. Nurse researchers have demonstrated that older person who age in place have better physical, psychological and cognitive outcomes. Less, however, is known about older persons who are "aging out of place," meaning out of their country of origin. With the growth of home health care, there is a need to understand the older immigrants' meaning of home when ageing out of their country of origin. DESIGN AND METHOD An inductive, qualitative descriptive research design was used. Seventeen Hispanic participants, ranging in age from 65 to 83 years were interviewed using a semi-structured interview protocol. FINDINGS Two major finding of the study focused on participants' descriptions of home in their country of origin and in the USA. The majority of participants described their home in their native country as the community, countryside or town (pueblo) and in the U.S.A. as family. The level of social isolation and loneliness among participants was evident. CONCLUSIONS Older Hispanic immigrants who are "aging out of place" integrate their past experiences of sense of place in their native country with their present experiences of home in the USA. The need to understand the role of the community and the family in the provision of nursing care in the home may be more important than the physical structure or setting in which it is delivered. Further intra- and cross-national studies are needed to provide a framework for understanding the issues of ageing and immigration globally. IMPLICATIONS FOR PRACTICE Gerontological nurses need to recognise the complexity of family relationships for older Hispanic persons who are ageing out of place of origin and their risk of depression, social isolation, and loneliness.

Racial and ethnic variations in phthalate metabolite concentration changes across full-term pregnancies. JOURNAL OF EXPOSURE SCIENCE & ENVIRONMENTAL EPIDEMIOLOGY 2017; 27:160-166. [PMID: 26860587 PMCID: PMC4980273 DOI: 10.1038/jes.2016.2] [Citation(s) in RCA: 43] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/09/2015] [Accepted: 11/25/2015] [Indexed: 05/18/2023]
Abstract
Higher concentrations of certain phthalate metabolites are associated with adverse reproductive and pregnancy outcomes, as well as poor infant/child health outcomes. In non-pregnant populations, phthalate metabolite concentrations vary by race/ethnicity. Few studies have documented racial/ethnic differences between phthalate metabolite concentrations at multiple time points across the full-course of pregnancy. The objective of the study was to characterize the change in phthalate metabolite concentrations by race/ethnicity across multiple pregnancy time points. Women were participants in a prospectively collected pregnancy cohort who delivered at term (≥37 weeks) and had available urinary phthalate metabolite concentrations for ≥3 time points across full-term pregnancies (n=350 women). We assessed urinary concentrations of eight phthalate metabolites that were log-transformed and specific gravity-adjusted. We evaluated the potential racial/ethnic differences in phthalate metabolite concentrations at baseline (median 10 weeks gestation) using ANOVA and across pregnancy using linear mixed models to calculate the percent change and 95% confidence intervals adjusted for sociodemographic and lifestyle factors. Almost 30% of the population were non-Hispanic black or Hispanic. With the exception of mono-(3-carboxypropyl) (MCPP) and di-ethylhexyl phthalate (DEHP) metabolites, baseline levels of phthalate metabolites were significantly higher in non-whites (P<0.05). When evaluating patterns by race/ethnicity, mono-ethyl phthalate (MEP) and MCPP had significant percent changes across pregnancy. MEP was higher in Hispanics at baseline and decreased in mid-pregnancy but increased in late pregnancy for non-Hispanic blacks. MCPP was substantially higher in non-Hispanic blacks at baseline but decreased later in pregnancy. Across pregnancy, non-Hispanic black and Hispanic women had higher concentrations of certain phthalate metabolites. These differences may have implications for racial/ethnic differences in adverse pregnancy and child health outcomes.
