Faculty, Staff and Student Publications

COVID-19 vaccination is being rapidly rolled out in the US and many other countries, and it is crucial to provide fast and accurate assessment of vaccination coverage and vaccination gaps to make strategic adjustments promoting vaccine coverage. We reported the effective use of real-time geospatial analysis to identify barriers and gaps in COVID-19 vaccination in a minority population living in South Texas on the US-Mexico Border, to inform vaccination campaign strategies. We developed 4 rank-based approaches to evaluate the vaccination gap at the census tract level, which considered both population vulnerability and vaccination priority and eligibility. We identified areas with …

Faculty, Staff and Student Publications

BACKGROUND: Previous studies have shown that various social determinants of health (SDOH) may have contributed to the disparities in COVID-19 incidence and mortality among minorities and underserved populations at the county or zip code level.

OBJECTIVE: This analysis was carried out at a granular spatial resolution of census tracts to explore the spatial patterns and contextual SDOH associated with COVID-19 incidence from a Hispanic population mostly consisting of a Mexican American population living in Cameron County, Texas on the border of the United States and Mexico. We performed age-stratified analysis to identify different contributing SDOH and quantify their effects by …

Trends In Race/Ethnicity Of Pediatric Residents And Fellows: 2007-2019, Kimberly Montez, Emma A Omoruyi, Kenya Mcneal-Trice, Wendy J Mack, Lahia Yemane, Alissa R Darden, Christopher J Russell

Faculty, Staff and Student Publications

BACKGROUND AND OBJECTIVES: A diverse pediatric workforce reflecting the racial/ethnic representation of the US population is an important factor in eliminating health inequities. Studies reveal minimal improvements over time in the proportions of underrepresented in medicine (URiM) physicians; however, studies assessing trends in pediatric URiM trainee representation are limited. Our objective was to evaluate longitudinal trends in racial/ethnic representation among a cross-section of US pediatric trainees and to compare it to the US population.

METHODS: Repeated cross-sectional study of graduate medical education census data on self-reported race/ethnicity of pediatric residents and subspecialty fellows from 2007 to 2019. To evaluate trends …

Association Of Long-Term Trajectories Of Neighborhood Socioeconomic Status With Weight Change In Older Adults, Dong Zhang, Cici Bauer, Tiffany Powell-Wiley, Qian Xiao

Faculty, Staff and Student Publications

IMPORTANCE: Studying long-term changes in neighborhood socioeconomic status (SES) may help to better understand the associations between neighborhood exposure and weight outcomes and provide evidence supporting neighborhood interventions. Little previous research has been done to examine associations between neighborhood SES and weight loss, a risk factor associated with poor health outcomes in the older population.

OBJECTIVE: to determine whether improvements in neighborhood SES are associated with reduced likelihoods of excessive weight gain and excessive weight loss and whether declines are associated with increased likelihoods of these weight outcomes.

DESIGN, STUDY, AND PARTICIPANTS: This cohort study was conducted using data from …

Structural Racism And Immigrant Health: Exploring The Association Between Wage Theft, Mental Health, And Injury Among Latino Day Laborers, Maria Eugenia Fernández-Esquer, Lynn N Ibekwe, Rosalia Guerrero-Luera, Yesmel A King, Casey P Durand, John S Atkinson

Faculty, Staff and Student Publications

BACKGROUND: Although wage theft has been discussed primarily as a labor and human rights issue, it can be conceptualized as an issue of structural racism with important consequences for immigrant health.

OBJECTIVES: The objectives of this study were to: 1) identify sociodemographic, employment, and stress-related characteristics that increase Latino day laborers' odds of experiencing wage theft; 2) assess the association between wage theft and serious work-related injury; 3) assess the association between wage theft and three indicators of mental health-depression, social isolation, and alcohol use-as a function of wage theft; and 4) assess serious work-related injury as a function of …

Faculty, Staff and Student Publications

Variation in levels of the human metabolome reflect changes in homeostasis, providing a window into health and disease. The genetic impact on circulating metabolites in Hispanics, a population with high cardiometabolic disease burden, is largely unknown. We conducted genome-wide association analyses on 640 circulating metabolites in 3,926 Hispanic Community Health Study/Study of Latinos participants. The estimated heritability for 640 metabolites ranged between 0%-54% with a median at 2.5%. We discovered 46 variant-metabolite pairs (p value < 1.2 × 10

Prenatal Depression And Risk Of Short Interpregnancy Interval In A Predominantly Puerto Rican Population, Sami Backley, Alex Knee, Penelope Pekow, Glenn Markenson, Katharine O White, Corina Schoen, Lisa Chasan-Taber

Faculty, Staff and Student Publications

Background: Short interpregnancy interval (IPI) is associated with risk of adverse pregnancy outcomes; however, few studies have evaluated the role of depression as a risk factor for short IPI. Puerto Rican women in the United States experience disparities in adverse birth outcomes and have the highest birth rates.

Methods: We analyzed the association between prenatal depressive symptoms and IPI in Proyecto Buena Salud, a prospective cohort of predominantly Puerto Rican women in Western Massachusetts (2006–2011). Depression was measured using the Edinburgh Postnatal Depression Scale (EPDS) in early, mid, and late pregnancy. We calculated follow-up time as the difference between the …

Faculty, Staff and Student Publications

BACKGROUND: Latino day laborers face substantial injuries at work. We present a comprehensive assessment of their injury experience and explore the predictors of selfreported injuries.

METHODS: Worker and injury characteristics were collected from 331 day laborers using an innnovative injury assessment tool. The odds of injury were estimated using a logistic regression.

RESULTS: Participants were foreign-born, Spanish monolingual, and employed in construction. Sixty-seven individuals reported 88 past-year injuries, mostly involving the upper or lower extremities. Injuries were caused by moving heavy objects, falling, or being struck an object. Of the documented injuries, 24% were not reported at work due to …

Exposures At Day Labor Corners: Using Existing Georeferenced Data To Describe Features Of Urban Environments, Maria Eugenia Fernández-Esquer, Amy E Hughes, Sandi L Pruitt

Faculty, Staff and Student Publications

PURPOSE: Latino day laborers are male immigrants from mainly Mexico and Central America who congregate at corners, that is, informal hiring sites, to solicit short-term employment. Studies describing the occupational environment of Latino day laborers traditionally measure jobsite exposures, not corner exposures. We sought to elucidate exposures at corners by describing their demographic, socioeconomic, occupational, business, built, and physical environmental characteristics and by comparing corner characteristics with other locations in a large urban county in Texas.

METHODS: We used multiple publicly available data sets from the U.S. Census, local tax authority, Google's Nearby Places Application Programming Interface, and Environmental Protection …

BACKGROUND: The electrocardiographically quantified QRS duration measures ventricular depolarization and conduction. QRS prolongation has been associated with poor heart failure prognosis and cardiovascular mortality, including sudden death. While previous genome-wide association studies (GWAS) have identified 32 QRS SNPs across 26 loci among European, African, and Asian-descent populations, the genetics of QRS among Hispanics/Latinos has not been previously explored.

METHODS: We performed a GWAS of QRS duration among Hispanic/Latino ancestry populations (n = 15,124) from four studies using 1000 Genomes imputed genotype data (adjusted for age, sex, global ancestry, clinical and study-specific covariates). Study-specific results were combined using fixed-effects, inverse variance-weighted …

Prevalence And Patterns Of Sexting Among Ethnic Minority Urban High School Students, Melissa Fleschler Peskin, Christine M Markham, Robert C Addy, Ross Shegog, Melanie Thiel, Susan R Tortolero

Faculty, Staff and Student Publications

Although sexting among U.S. youth has received much popular media attention, there are only limited data on its prevalence among ethnic minority youth. This study, therefore, specifically examined the prevalence and patterns of sexting (sending and/or receiving a nude or semi-nude picture/video or a sexual text-only message) among a sample of black and Hispanic youth. Data from 1,034 tenth graders from a large, urban school district in southeast Texas were used to calculate the prevalence of sexting by gender-race/ethnicity. Overlap among sexting behaviors was also examined. Electronic surveys were administered via an audio-computer-assisted self-interview on laptop computers. Prevalence estimates were …

Spina Bifida Subtypes And Sub-Phenotypes By Maternal Race/Ethnicity In The National Birth Defects Prevention Study, A J Agopian, Mark A Canfield, Richard S Olney, Philip J Lupo, Tunu Ramadhani, Laura E Mitchell, Gary M Shaw, Cynthia A Moore

Faculty, Staff and Student Publications

Spina bifida refers to a collection of neural tube defects, including myelomeningocele, meningocele, and myelocele (SB(M) ), as well as lipomyelomeningocele and lipomeningocele (SB(L) ). Maternal race/ethnicity has been associated with an increased risk for spina bifida among offspring. to better understand this relationship, we evaluated different spina bifida subtypes (SB(M) vs. SB(L) ) and sub-phenotypes (anatomic level or presence of additional malformations) by maternal race/ethnicity using data from the National Birth Defects Prevention Study. This study is a large, multisite, population-based study of nonsyndromic birth defects. Prevalence estimates were obtained using data from spina bifida cases (live births, fetal …

Multiple Independent Genetic Factors At Nos1ap Modulate The Qt Interval In A Multi-Ethnic Population, Dan E. Arking, Amit Khera, Chao Xing, W H Linda Kao, Wendy Post, Eric Boerwinkle, Aravinda Chakravarti

Faculty, Staff and Student Publications

Extremes of electrocardiographic QT interval are associated with increased risk for sudden cardiac death (SCD); thus, identification and characterization of genetic variants that modulate QT interval may elucidate the underlying etiology of SCD. Previous studies have revealed an association between a common genetic variant in NOS1AP and QT interval in populations of European ancestry, but this finding has not been extended to other ethnic populations. We sought to characterize the effects of NOS1AP genetic variants on QT interval in the multi-ethnic population-based Dallas Heart Study (DHS, n = 3,072). The SNP most strongly associated with QT interval in previous samples …
