RESUMO
Mexican Americans have a high prevalence of diabetes and burden of diabetes-related complications, highlighting the need for novel preventive strategies and noninvasive predictors of diabetes risk tailored to this population. Changes in the gut microbiome have the potential to predict diabetes. Here, we aimed to identify alterations in the gut microbiome associated with diabetes in the high-risk population of Mexican Americans in South Texas. Stool samples were collected from 216 subjects from the population-based Cameron County Hispanic Cohort. Among them, 75 had type 2 diabetes. Taxonomic and functional profiling of the stool samples were assessed by 16S and shotgun metagenomic sequencing, and the influence of genetic factors was explored. The gut microbiome of subjects with diabetes was enriched with proinflammatory Proteobacteria members (Enterobacteriaceae, Escherichia-Shigella) and depleted of butyrate-producing Clostridiales members (Faecalibacterium prausnitzii, Peptostreptococcaceae, and Clostridium sensu stricto 1). The accompanying metagenomic changes in subjects with diabetes suggested dysregulated amino acid metabolism, reduced galacturonate and glucuronate catabolism (correlating with Faecalibacterium prausnitzii abundance), and enriched heme biosynthesis (correlating with Enterobacteriaceae abundance). Polymorphism rs7129790 near MMP27 was strongly associated with high Proteobacteria abundance and was more frequent in this cohort and in individuals of Mexican ancestry than in Europeans. In conclusion, Mexican Americans in South Texas with diabetes display distinct gut microbiome and metagenomic signatures. These signatures may have utility in risk modeling and disease prevention in this high-risk population. IMPORTANCE The gut microbiome composition varies across ethnicities and geographical locations, yet studies on diabetes-associated microbiome changes specific to high-risk Mexican Americans are lacking. Here, we aimed to identify specific alterations associated with diabetes in this population, as well as host genetic factors that may explain increased disease susceptibility in this ethnic group. Using samples from a population-based cohort of Mexican Americans with a high prevalence of obesity and diabetes, we confirmed findings from studies on other ethnicities that suggested promotion of a chronic proinflammatory environment, loss of butyrate production, and compromised intestinal barrier integrity. High abundance of proinflammatory Proteobacteria was associated with a polymorphism that was more frequent in this cohort and in individuals of Mexican ancestry than in Europeans. Validation of microbiome-based risk models for diabetes should be evaluated in prospective cohort studies.

BACKGROUND AND PURPOSE: Mexican Americans (MAs) have worse stroke outcomes and a different profile of multiple chronic conditions (MCC) compared with non-Hispanic White people. MCC has implications for stroke treatment, complications, and poststroke care, which impact poststroke functional outcome (FO). We sought to assess the contribution of MCC to the ethnic difference in FO at 90 days between MAs and non-Hispanic White people. METHODS: In a prospective cohort of ischemic stroke patients (2008-2016) from Nueces County, Texas, data were collected from patient interviews, medical records, and hospital discharge data. MCC was assessed using a stroke-specific and function-relevant index (range, 0-35; higher scores greater MCC burden). Poststroke FO was measured by an average score of 22 activities of daily living (ADLs) and instrumental ADLs at 90 days (range, 1-4; higher scores worse FO). The contribution of MCC to the ethnic difference in FO was assessed using Tobit regression. Effect modification by ethnicity was examined. RESULTS: Among the 896 patients, 70% were MA and 51% were women. Mean age was 68±12.2 years; 33% of patients were dependent in ADL/instrumental ADLs (FO score >3, representing a lot of difficulty with ADL/instrumental ADLs) at 90 days. MAs had significantly higher age-adjusted MCC burden compared with non-Hispanic White people. Patients with high MCC score (at the 75th percentile) on average scored 0.70 points higher in the FO score (indicating worse FO) compared with those with low MCC score (at the 25th percentile) after adjusting for age, initial National Institutes of Health Stroke Scale, and sociodemographic factors. MCC explained 19% of the ethnic difference in FO, while effect modification by ethnicity was not statistically significant. CONCLUSIONS: MAs had a higher age-adjusted MCC burden, which partially explained the ethnic difference in FO. The prevention and treatment of MCC could potentially mitigate poststroke functional impairment and lessen ethnic disparities in stroke outcomes.

OBJECTIVES: We conducted a cluster randomized controlled trial to test the a priori hypothesis that students attending an intervention middle school would be less likely to report physical adolescent relationship abuse (ARA) 1 year later compared with students attending a control school. Secondary objectives were to determine if the intervention reduced substance misuse, bullying, and fighting. METHODS: Twenty-four Texas public middle schools were matched by the size of student enrollment, number of economically disadvantaged students, and race and ethnicity of the student body and randomly assigned to the intervention (n = 12; 1237 participants) or the control (n = 12; 1531participants) group. The intervention, Fourth R, is a classroom-based curriculum delivered by existing teachers and consists of 21 lessons on injury prevention, substance use, and growth and development. RESULTS: Participants (50% female) self-reported ethnicity as Hispanic or Latinx (35%), Black or African American (24%), Asian American (17%), White (8%), and multiethnicity or other (16%). Among those who have dated, students in the intervention schools were less likely to report perpetrating physical ARA (intervention = 14.9% versus control = 18.3%) relative to students in the control schools (adjusted odds ratio, 0.66; 95% confidence interval, 0.43-1.00; P = .05). In the overall sample, no significant differences emerged between control and intervention groups with respect to substance misuse, fighting, and bullying. CONCLUSIONS: The middle school version of Fourth R is effective in reducing physical ARA perpetration over at least 1 year. The intervention did not have an effect on bullying perpetration, physical fighting with peers, and substance misuse. Long-term assessment, especially follow-up that covers the transition to high school, is needed to examine the program benefit on key outcomes.

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 the highest vaccination gaps using different assessment approaches. Real-time geospatial analysis to identify vaccination gaps is critical to rapidly increase vaccination uptake, and to reach herd immunity in the vulnerable and the vaccine hesitant groups. Our results assisted the City of Brownsville Public Health Department in adjusting real-time targeting of vaccination, gathering coverage assessment, and deploying services to areas identified as high vaccination gap. The analyses and responses can be adopted in other locations.

OBJECTIVES: There are currently 1,308,327 immigrants in removal proceedings, over 80% of whom are Latinx (TRAC, 2021b). This study examined the relation among putative protective markers (i.e. social support, religious support, and legal support) and the emotional and physical well-being of Latinx individuals facing removal proceedings. HYPOTHESES: We hypothesized that increased social support, religious support, and legal support would buffer the negative relations between hopelessness, poor self-efficacy, and well-being measures (depression, anxiety, stress, mental well-being, somatic symptoms, and physical well-being). METHOD: Participants (N = 157; 31.2% men, M age = 33.4 years) had an active immigration court case in Texas and completed a demographic questionnaire, the Beck Hopelessness Scale, General Self-Efficacy Scale, Multidimensional Scale of Perceived Social Support, Multi-Faith Religious Support Scale, Depression, Anxiety, Stress Scale-21, Patient Health Questionnaire-15, and Short Form Health Survey-12. RESULTS: Higher levels of hopelessness and poor self-efficacy were associated with more negative well-being outcomes, while social support was associated with more positive well-being outcomes. Contrary to hypotheses, religious support and legal support served as risk markers independently, while legal support interacted with hopelessness, such that decreased legal support was associated with higher mental well-being at lower levels of hopelessness and interacted with poor self-efficacy, such that increased legal support was associated with poorer mental well-being at lower levels of self-efficacy. All effect sizes were small (rsp2 = .04 to .16). CONCLUSIONS: Targeting hopelessness and poor self-efficacy while promoting social support may help mental health professionals improve the well-being of immigrants in removal proceedings.

BACKGROUND: Since February 2020, over 2.5 million Texans have been diagnosed with COVID-19, and 20% are young adults at risk for SARS-CoV-2 exposure at work, academic, and social settings. This study investigated demographic and clinical risk factors for severe disease and readmission among young adults 18-29 years old, who were diagnosed at a hospital encounter in Houston, Texas, USA. METHODS AND FINDINGS: A retrospective registry-based chart review was conducted investigating demographic and clinical risk factors for severe COVID-19 among patients aged 18-29 with positive SARS-CoV-2 tests within a large metropolitan healthcare system in Houston, Texas, USA. In the cohort of 1,853 young adult patients diagnosed with COVID-19 infection at a hospital encounter, including 226 pregnant women, 1,438 (78%) scored 0 on the Charlson Comorbidity Index, and 833 (45%) were obese (≥30 kg/m2). Within 30 days of their diagnostic encounter, 316 (17%) patients were diagnosed with pneumonia, 148 (8%) received other severe disease diagnoses, and 268 (14%) returned to the hospital after being discharged home. In multivariable logistic regression analyses, increasing age (adjusted odds ratio [aOR] 1.1, 95% confidence interval [CI] 1.1-1.2, p<0.001), male gender (aOR 1.8, 95% CI 1.2-2.7, p = 0.002), Hispanic ethnicity (aOR 1.9, 95% CI 1.2-3.1, p = 0.01), obesity (3.1, 95% CI 1.9-5.1, p<0.001), asthma history (aOR 2.3, 95% CI 1.3-4.0, p = 0.003), congestive heart failure (aOR 6.0, 95% CI 1.5-25.1, p = 0.01), cerebrovascular disease (aOR 4.9, 95% CI 1.7-14.7, p = 0.004), and diabetes (aOR 3.4, 95% CI 1.9-6.2, p<0.001) were predictive of severe disease diagnoses within 30 days. Non-Hispanic Black race (aOR 1.6, 95% CI 1.0-2.4, p = 0.04), obesity (aOR 1.7, 95% CI 1.0-2.9, p = 0.046), asthma history (aOR 1.7, 95% CI 1.0-2.7, p = 0.03), myocardial infarction history (aOR 6.2, 95% CI 1.7-23.3, p = 0.01), and household exposure (aOR 1.5, 95% CI 1.1-2.2, p = 0.02) were predictive of 30-day readmission. CONCLUSIONS: This investigation demonstrated the significant risk of severe disease and readmission among young adult populations, especially marginalized communities and people with comorbidities, including obesity, asthma, cardiovascular disease, and diabetes. Health authorities must emphasize COVID-19 awareness and prevention in young adults and continue investigating risk factors for severe disease, readmission and long-term sequalae.

This study introduces an innovative methodological approach to identify potential drivers of structuring HIV-1 transmission clustering patterns between different subpopulations in the culturally and racially/ethnically diverse context of Houston, TX, the largest city in the Southern United States. Using 6332 HIV-1 pol sequences from persons newly diagnosed with HIV during the period 2010-2018, we reconstructed HIV-1 transmission clusters, using the HIV-TRAnsmission Cluster Engine (HIV-TRACE); inferred demographic and risk parameters on HIV-1 transmission dynamics by jointly estimating viral transmission rates across racial/ethnic, age, and transmission risk groups; and modeled the degree of network connectivity by using generalized estimating equations (GEE). Our results indicate that Hispanics/Latinos are most vulnerable to the structure of transmission clusters and serve as a bridge population, acting as recipients of transmissions from Whites (3.0 state changes/year) and from Blacks (2.6 state changes/year) as well as sources of transmissions to Whites (1.8 state changes/year) and to Blacks (1.2 state changes/year). There were high rates of transmission and high network connectivity between younger and older Hispanics/Latinos as well as between younger and older Blacks. Prevention and intervention efforts are needed for transmission clusters that involve younger racial/ethnic minorities, in particular Hispanic/Latino youth, to reduce onward transmission of HIV in Houston.

Examining variation in reasoning about sustainability between diverse populations provides unique insight into how group norms surrounding resource conservation develop. Cultural institutions, such as religious organizations and formal schools, can mobilize communities to solve collective challenges associated with resource depletion. This study examined conservation beliefs in a Western industrialized (Austin, Texas, USA) and a non-Western, subsistence agricultural community (Tanna, Vanuatu) among children, adolescents, and adults (N = 171; n = 58 7-12-year-olds, n = 53 13-17-year-olds, and n = 60 18-68-year-olds). Participants endorsed or rejected four types of justifications for engaging in land and animal conservation: sustainability, moral, religious, or permissible. In both populations, participants endorsed sustainability justifications most frequently. Religious justifications increased with age in Tanna and decreased with age in Austin. Tannese participants were also more likely to endorse multiple justifications for conservation than Austin participants. Data across all justification types show a main effect of age in both communities; endorsement of conservation decreased with age in Austin, but increased with age in Tanna. Across age groups, participants were more likely to endorse the conservation of animals than land in Austin, yet equally as likely to endorse the conservation of land and animals in Tanna. Overall, these results reveal similarities and differences in the beliefs that support the conservation of natural resources across populations.

BACKGROUND: Diversion programs are considered alternatives to the arrest and incarceration of non-violent drug offenders, including those found in possession of smaller amounts of cannabis in states with prohibitive laws. Despite the progressive nature of such programs, the inability to complete diversion program requirements can often result in greater involvement with the criminal justice system than traditional case adjudication. Few studies have evaluated racial group differences in cannabis diversion program completion. METHODS: The current study examined a sample of 8323 adult participants in Harris County, Texas' Marijuana Misdemeanor Diversion Program (MMDP) between March 2017 and July 2019. Gender, age, and race/ethnicity were examined as predictors of program completion and time to completion using Chi square, Kruskal Wallis tests, and Cox proportional hazard regression models. RESULTS: Both males and African Americans were over-represented (80 % and 50 %, respectively) among participants of Harris County's MMDP. African American (HR = 0.782, 95 % CI [.735-.832], p < .001) and Latino American MMDP participants (HR = .822, 95 % CI [.720-.937], p = .003) had significantly lower odds of MMDP completion and a longer interval to program completion as compared to non-Latino White participants. CONCLUSIONS: The current study identified racial/ethnic and gender disparities in a large county's cannabis diversion program. These findings may be related to law enforcement disparities which disproportionately target males and people of color. Findings may serve to inform the continued reform of the criminal justice system, particularly laws relating to cannabis.

BACKGROUND AND PURPOSE: Stroke incidence and mortality are declining rapidly in developed countries. Little data on ethnic-specific stroke recurrence trends exist. Fourteen-year stroke recurrence trend estimates were evaluated in Mexican Americans and non-Hispanic whites in a population-based study. METHODS: Recurrent stroke was ascertained prospectively in the population-based BASIC (Brain Attack Surveillance in Corpus Christi) project in Texas, between 2000 and 2013. Incident cases were followed forward to determine 1- and 2-year recurrence. Fine & Gray subdistribution hazard models were used to estimate adjusted trends in the absolute recurrence risk and ethnic differences in the secular trends. The ethnic difference in the secular trend was examined using an interaction term between index year and ethnicity in the models adjusted for age, sex, hypertension, diabetes mellitus, smoking, atrial fibrillation, insurance, and cholesterol and relevant interaction terms. RESULTS: From January 1, 2000 to December 31, 2013 (N=3571), the cumulative incidence of 1-year recurrence in Mexican Americans decreased from 9.26% (95% CI, 6.9%-12.43%) in 2000 to 3.42% (95% CI, 2.25%-5.21%) in 2013. Among non-Hispanic whites, the cumulative incidence of 1-year recurrence in non-Hispanic whites decreased from 5.67% (95% CI, 3.74%-8.62%) in 2000 to 3.59% (95% CI, 2.27%-5.68%) in 2013. The significant ethnic disparity in stroke recurrence existed in 2000 (risk difference, 3.59% [95% CI, 0.94%-6.22%]) but was no longer seen by 2013 (risk difference, -0.17% [95% CI, -1.96% to 1.5%]). The competing 1-year mortality risk was stable over time among Mexican Americans, while for non-Hispanic whites it was decreasing over time (difference between 2000 and 2013: -4.67% [95% CI, -8.72% to -0.75%]). CONCLUSIONS: Mexican Americans had significant reductions in stroke recurrence despite a stable death rate, a promising indicator. The ethnic disparity in stroke recurrence present early in the study was gone by 2013.

BACKGROUND: Human milk is the preferred source of infant nourishment; yet, acceptance of human milk as the norm for infant feeding is debated. In the United States there is a disparity in breastfeeding rates, which are significantly lower in African Americans compared to Whites. Multiple variables appear to influence breastfeeding, including the male partner. OBJECTIVES: To assess and compare breastfeeding exposure, attitude, and knowledge between African American and White college males with no biological children. A second objective was to explore the relationship between breastfeeding variables and educational attainment, academic major, and sibling presence. METHODS: A subset of responses from a larger cross-sectional survey were analyzed. African American and White collegiate males aged 18-40 years without biological children were included in the study. The questionnaire included demographic, exposure, attitude, and knowledge items. RESULTS: A total of 117 African American and 713 White males were included and represented all academic colleges on campus. African American participants documented less exposure to breastfeeding, a more positive attitude, and similar poor knowledge scores compared to their White counterparts. Sibling presence was linked with exposure, and exposure was linked to attitude. Both African American and White science majors scored higher on all factors than humanities or business majors. CONCLUSIONS FOR PRACTICE: Breastfeeding exposure influences males' attitudes toward breastfeeding. Future research should consider types of exposure to identify the sources most influential. Furthermore, tailoring breastfeeding interventions to increase exposure and knowledge in core wellness courses may improve attitudes and social acceptance among collegiate males.

BACKGROUND: Among Latinas with breast cancer, residence in an ethnic enclave may be associated with survival. However, findings from prior studies are inconsistent. METHODS: The authors conducted parallel analyses of California and Texas cancer registry data for adult (aged ≥18 years) Latinas who were diagnosed with invasive breast cancer from 1996 to 2005, with follow-up through 2014. Existing indices applied to tract-level 2000 US Census data were used to measure Latinx enclaves and neighborhood socioeconomic status (nSES). Multivariable Cox proportional hazard models were fit for all-cause and breast cancer-specific survival adjusted for year of diagnosis, patient age, nativity (with multiple imputation), tumor stage, histology, grade, size, and clustering by census tract. RESULTS: Among 38,858 Latinas, the majority (61.3% in California and 70.5% in Texas) lived in enclaves. In fully adjusted models for both states, foreign-born women were found to be more likely to die of breast cancer and all causes when compared with US-born women. Living in enclaves and in neighborhoods with higher SES were found to be independently associated with improved survival from both causes. When combined into a 4-level variable, those in low nSES nonenclaves had worse survival for both causes compared with those living in low nSES enclaves and, in the all-cause but not breast cancer-specific models, those in high nSES neighborhoods, regardless of enclave status, had improved survival from all causes. CONCLUSIONS: Applying the same methods across 2 states eliminated previously published inconsistent associations between enclave residence and breast cancer survival. Future studies should identify specific protective effects of enclave residence to inform interventions.

BACKGROUND: The purpose of this study was to compare knowledge of a stroke education module provided to bilingual members of the Ethiopian immigrant population in Dallas, Texas, presented in the Amharic language as compared to in English. METHODS: A convenience sample of 84 participants were recruited using a snowball technique and randomly assigned to receive education in English or Amharic. The participants completed a pre- and posttest of their knowledge about strokes, a demographic survey, and a satisfaction survey. Data was analyzed using a general linear model and chi-square analysis. RESULTS: There were no statistically significant differences between satisfaction scores comparing those educated in Amharic versus English (χ2 = 6.5108, p = .0107). Although mean pretest (10.8) and posttest (16.4) stroke knowledge scores were higher across all groups (p < .001), the mean posttest scores were lower for subjects who watched the Amharic versus the English video (14.9 vs. 18.1, p = .003). CONCLUSION: This study did not show a statistically significant increase in knowledge about stroke when presented learning materials in subjects' native language compared to in English. The use of video to present stroke and stroke-risk educational content can be used in future research and global health initiatives to increase stroke knowledge in the Amharic-speaking community.

Objective: The severity and disease course of cutaneous lupus erythematosus (CLE) are highly variable. Consequently, outcome measures for CLE clinical improvement are heterogeneous, complicating treatment decisions and therapeutic development. This study characterises CLE outcome measures and identifies the influence of clinical improvement thresholds on strengths of associations with patient demographic and clinical factors. Methods: In this pilot cohort study, multivariable models identified factors associated with CLE activity and skin damage improvement, defined as relative decreases in Cutaneous Lupus Activity and Severity Index (CLASI) activity (CLASI-A) and damage (CLASI-D) scores, over ranges of response thresholds. Results: 66 patients with 119 visit-pairs were included in the CLASI-A analysis. 74 patients with 177 visit-pairs were included in the CLASI-D analysis. Factors associated with CLE activity and damage improvement depended on the response threshold. Some associations were stronger at more stringent thresholds, including subacute CLE predominance with increased likelihood of CLASI-A improvement (R2=0.73; 50% reduction: OR 1.724 (95% CI 0.537 to 5.536); 75%: 5.67 (95% CI 1.56 to 20.5)) and African-American race with decreased likelihood of CLASI-D improvement (R2=0.80; 20%: 0.40 (95% CI 0.17 to 0.93); 40%: 0.25 (95% CI 0.08 to 0.82)). Other associations were stable across multiple thresholds, including older age of CLE development with increased likelihood of CLASI-A improvement (R2=0.25; 50%: 1.05 (95% CI 1.01 to 1.09]; 75%: 1.05 (95% CI 1.00 to 1.10)) and higher initial disease activity with decreased likelihood of CLASI-D improvement (R2=0.55; 20%: 0.91 (95% CI 0.84 to 0.98); 40%: 0.88 (95% CI 0.79 to 0.97)). Conclusions: Examining a range of CLASI threshold outcomes can comprehensively characterise changes in disease course in patients with CLE. Insufficiently stringent thresholds may fail to distinguish meaningful clinical change from natural fluctuation in disease activity.

BACKGROUND: Inequity in adverse birth outcomes between black and white women in the U.S. is persistent, despite decades of research and prevention efforts. Neighborhood environments are plausibly related to pre-pregnancy health and other risk factors for adverse birth outcomes and may help explain black/white inequities. Despite the fact that neighborhoods change over time, most prior work has relied upon cross-sectional measures of neighborhood economic contexts. METHODS: We used birth certificates for non-Hispanic black and white women in Texas (2009-2011, Nâ¯=â¯470,896) to examine whether longitudinal measures of neighborhood economic context (poverty and income inequality, based on census tract data from 1990 to 2010) were associated with preterm birth, low birthweight and small-for-gestational-age (SGA) with hierarchical generalized linear models. We also tested whether (1) the longitudinal measures explained black/white inequities or (2) moderated the effect of race on the birth outcomes. Finally, we compared the models with longitudinal measures to models with cross-sectional measures of neighborhood economic context. RESULTS: Longitudinal measures of neighborhood economic context were associated with all three birth outcomes, but did not explain racial inequities. Except for income inequality and SGA, there was no evidence of moderation by race. Substituting cross-sectional measures of economic context for longitudinal ones resulted in similar findings. CONCLUSION: Policies that either address structural neighborhood-level economic disadvantage or mitigate the effects of such disadvantage are warranted to improve the health of mothers and prevent adverse birth outcomes.

Background: Although US cigarette smoking rates have steadily declined, the changing nature of nicotine consumption and the popularity of non-combustible nicotine products urges us to revise tobacco prevention strategies. Research on smoking perspectives among Hispanic youth is limited yet crucial for prevention efforts with Hispanics being the largest minority in the U.S.Objective: This study sought to understand the experience and perceptions of low-income Hispanic youth regarding tobacco use.Methods: Forty-nine adolescents (ages 9 to 19) from El Paso, Texas, participated in five extended focus group discussions about tobacco/nicotine use.Results: Adolescents were predominantly exposed to tobacco through relatives, although school and party contexts became more relevant as youth aged. Youth had negative perceptions of tobacco and smokers, but believed their peers often viewed tobacco positively. Youth also saw tobacco use as a functional stress-management strategy, especially within their extended family. Health and family were strong motivators not to smoke.Conclusions: Youth maintain several tensions in their views on tobacco. Tobacco use is considered unpleasant and harmful, yet youth perceive their peers to view it as cool. Peer to peer discussion of tobacco experiences and perceptions may help correct these incongruent viewpoints. Adding to this tension is the perception that tobacco is used to manage stress. Given the importance of the home environment for Hispanic youth, tobacco prevention efforts may benefit from engaging family to identify the ways in which tobacco use causes stress.

BACKGROUND: Low socioeconomic status (SES) is linked to failure to quit smoking. Health inequity models suggest that low SES smokers experience barriers to quitting in part due to greater exposure to pro-smoking social contexts. PURPOSE: The current study examined longitudinal associations among socioeconomic status, pro-smoking social context factors (i.e., exposure to other smokers, places where smoking was allowed), cigarette availability, and smoking lapse during a quit attempt. METHODS: Ecological momentary assessments (EMA) were gathered from a multiethnic sample of 365 smokers engaged in a quit attempt. A multilevel structural equation model estimated a latent variable for SES indicated by income, education, health insurance, and employment, associations among EMAs for pro-smoking social contexts and cigarette availability, and indirect effects of SES through, pro-smoking social contexts and cigarette availability to subsequent smoking lapse. RESULTS: Lower SES scores were associated with a higher likelihood of smoking lapse. Decomposition of the path from SES to smoking lapse into indirect effects showed significant paths through exposure to places where smoking is allowed and cigarette availability. Additionally, significant serial indirect paths from SES through both exposure to other smokers and places where smoking was allowed, in turn, through cigarette availability, and, ultimately, to smoking lapse were noted. CONCLUSIONS: Consistent with models positing that SES influences health behaviors via contextual factors, the current study demonstrated that low SES smokers attempting to quit experienced greater pro-smoking social contexts that affected subsequent risk for lapse.

Annually, retirees known as Winter Texans travel to spend the winter along the Texas/Mexico border and while there, many purchase medicine in Mexico. However, strategies that are used when purchasing Mexican medicine and the health implications of doing so have not been adequately explored. The results of the study we report illustrate that Winter Texans are knowledgeable about their healthcare and act more as choice-making consumers than patients seeking care. Furthermore, the use of Mexican medication did not increase rates of adverse drug events or decrease health-related quality of life scores.

BACKGROUND: There is considerable variability in the prevalence of birth defects among racial/ethnic groups. This study estimated birth defect prevalence among the less studied non-Hispanic (NH) Asian/Pacific Islander (PI) and American Indian/Alaska Native (AI/AN) populations in Texas relative to NH Whites. METHODS: Data were obtained from the Texas Birth Defect Registry from 1999 to 2015 for deliveries to Texas-resident women who were NH White, NH Asian/PI, or AI/AN. This covers a live birth population of 2.6 million. Prevalence ratios and 95% confidence intervals (95% CIs) were calculated for NH Asian/PIs and AI/ANs (relative to NH Whites) for 44 birth defects using Poisson regression adjusting for maternal age. RESULTS: After adjustment there were 33 statistically significant prevalence ratios (aPRs). Among NH Asian/PIs, 23 defects had a lower aPR (0.38-0.86) and three defects had a higher aPR (1.19-2.50). AI/ANs had one defect with a significantly lower aPR (0.64) and six with a higher aPR (1.36-4.63). CONCLUSIONS: Non-Hispanic Asian/PIs generally have a lower prevalence ratio for many birth defects while AI/ANs have a higher prevalence ratio compared to NH Whites. These findings update the limited literature on this topic and warrant additional research to identify the true associations across a range of birth defects among these understudied racial/ethnic groups.
