Ethnic discrimination, acculturative stress, and sexual risk among Latinx emerging adults: Examining moderation effects of familism support and ethnic identity.

OBJECTIVES: Ethnic discrimination and acculturative stress play an important role in sexual risk behaviors for Latinx emerging adults, who are at disproportionate risk for sexually transmitted infections. Factors such as familism support and ethnic identity may be protective, yet research is limited. This study is guided by a culturally adapted stress and coping framework to examine associations of ethnic discrimination and acculturative stress with sexual risk behaviors (i.e., multiple sex partners, alcohol or drug use before sex, and condomless sex with a primary or casual partner), and examine the moderating roles of familism support and ethnic identity among Latinx emerging adults. METHOD: Participants were recruited from Arizona and Florida and were primarily female (51.3%) with a mean age of 21.48 years (SD = 2.06). Using cross-sectional data from 158 sexually active Latinx emerging adults, this study employed multiple logistic regression and moderation analyses. RESULTS: Higher levels of ethnic discrimination and pressure to acculturate were associated with fewer sex partners, and higher levels of pressure against acculturation were associated with increased condomless sex with a casual partner. The moderation effect of higher levels of familism support on pressure to acculturate was associated with fewer sex partners, and the moderation effect of higher levels of ethnic identity on pressure against acculturation was associated with decreased condomless sex with casual partners. CONCLUSIONS: Examining the results within a culturally informed theoretical framework supports that protective factors may help mitigate sexual risk factors among Latinx emerging adults experiencing acculturative stress.

Factors Associated With COVID-19 Vaccination Among Racial/Ethnic Minority Groups With HIV in South Florida.

BACKGROUND: Racial/ethnic minority groups with HIV in the United States are particularly vulnerable to COVID-19 consequences and can significantly benefit from increased uptake of COVID-19 vaccines. This study identified factors associated with full COVID-19 vaccination among people with HIV. SETTING: Ryan White HIV/AIDS Program in Miami-Dade County, FL. METHODS: Data were collected from 299 Ryan White HIV/AIDS Program adult clients during January-March 2022 using a cross-sectional phone survey. Multivariable logistic regression was used to estimate adjusted odds ratios (aORs) with 95% confidence intervals (CIs). All analyses were weighted to be representative of the race/ethnicity and sex distribution of clients in the Ryan White HIV/AIDS Program. RESULTS: Eighty-four percent of participants were fully vaccinated with a primary vaccine series; stratified by race/ethnicity, the percentages were 88.9% of Hispanic, 72.0% of black/African American, and 67.5% of Haitian participants. Fully vaccinated participants were less likely to be black/African American than Hispanic (aOR = 0.18; 95% CI: 0.05 to 0.67) and more likely to not endorse any misconceptions about COVID-19 vaccines (aOR = 8.26; 95% CI: 1.38 to 49.64), to report encouragement to get vaccinated from sources of information (aOR = 20.82; 95% CI: 5.84 to 74.14), and to perceive that more than 50% of their social network was vaccinated (aOR = 3.35; 95% CI: 1.04 to 10.71). Experiences of health care discrimination, structural barriers to access vaccines, and recommendations from HIV providers were not associated with full vaccination. CONCLUSIONS: These findings highlight the importance of delivering accurate and positive messages about vaccines and engaging social networks to promote COVID-19 vaccination among people with HIV. This information can be leveraged to promote uptake of subsequent boosters and other recommended vaccines.

Increased alcohol use during the COVID-19 pandemic among people with HIV from racial/ethnic minority groups in South Florida.

People with HIV (PWH) from racial/ethnic minority groups may be particularly vulnerable to the effects of the COVID-19 Pandemic. Exacerbated COVID-19-related stressors may lead to maladaptive coping mechanisms such as increased alcohol use. This study examined socioeconomic and psychosocial predictors of increased alcohol use during the first year of the COVID-19 Pandemic among PWH from racial/ethnic minority groups in South Florida. Data were collected from Ryan White Program clients during October 2020-January 2021 using a cross-sectional phone survey, and were analyzed using logistic regression modeling. Among 139 participants, 20% reported increased alcohol use. Findings showed that being unable to buy needed food (adjusted odds ratio [aOR]: 3.37; 95% confidence interval [CI]: 1.01-11.31) and spending more time caring for children (aOR: 5.22, 95% CI: 1.61-16.88) was associated with increased alcohol use during the Pandemic. Providing support to alleviate food insecurity and manage caregiving burden during public health crises like the COVID-19 Pandemic might help prevent increases in alcohol use among PWH.

Barriers and facilitators to retention in care and treatment adherence among racially/ethnically diverse women with HIV in South Florida: a qualitative study.

Women, particularly those from racial/ethnic minority groups, experience disparities in HIV care and treatment, and in achieving viral suppression. This study identified barriers and facilitators influencing retention in HIV care and treatment adherence among women belonging to racial/ethnic minority groups. We conducted semi-structured interviews with 74 African American, Hispanic/Latina and Haitian cisgender women receiving care from the Ryan White HIV/AIDS Program in Miami-Dade County, Florida in 2019. Data were analyzed using a thematic analysis approach. The most salient barriers faced by women were competing life priorities, mental health and substance use issues, medication-related concerns and treatment burden, negative experiences with HIV care services, transportation and parking issues and stigma and discrimination. Important facilitators identified by women included taking personal responsibility for health, social support, and patient-friendly and supportive HIV care services. Our findings suggest that HIV care could be enhanced for this population by understanding the non-HIV needs of the women in care, provide more flexible and relevant services in response to the totality of these needs, and simplify and expand access to care and supportive services.

Clients' Perspectives on Patient-Centeredness: a Qualitative Study with Low-Income Minority Women Receiving HIV Care in South Florida.

Low-income, minority women living with HIV often experience multiple barriers in care that contribute to suboptimal care outcomes. Medical case managers (MCM) and medical providers are key players involved in care coordination and aid women along the HIV care continuum. The objective of this study was to identify current and potential patient-centered practices that facilitate adherence to medication and retention in care, from the perspective of racially and ethnically diverse women living with HIV. We implemented a qualitative study using semi-structured interviews with 75 African American, Hispanic/Latina, and Haitian women who were enrolled in the Ryan White HIV/AIDS Program in South Florida in 2019. We organized domains of exploration using a patient-centered care framework to identify practices in which providers acknowledged, respected, and responded to clients' preferences, needs, and values. Interviews were analyzed using consensual thematic analysis approach. Findings reflect women valued MCMs who were proactive and directive in care, provided motivation, and aided with navigation of shame, fear, and stigma. Women valued medical providers who upheld simple educational communication. Moreover, women reported that providers who reviewed medical results with clients, incorporated questions about families, and inquired about multiple physical and clinical needs beyond HIV created opportunities for women to feel respected, valued, and in turn, enhanced their involvement in their care. Findings identify specific interpersonal practices that can enhance the ability to better meet the needs of diverse groups of women, specifically those from racial/ethnic minority groups who face multiple sociocultural barriers while in care.

Post-immigration factors affecting retention in HIV care and viral suppression in Latin American and Caribbean immigrant populations in the United States: a systematic review.

OBJECTIVES: To reduce disparities in HIV care outcomes among Latin American and Caribbean (LAC) immigrants living with HIV in the U.S., it is necessary to identify factors influencing HIV care in this population. A systematic review that provides a comprehensive understanding of factors influencing retention in HIV care and viral suppression among LAC immigrants living with HIV in the U.S. is lacking. This systematic review used the Immigrant Health Services Utilization theoretical framework to provide an understanding of these factors. DESIGN: We searched for peer-reviewed publications in MEDLINE, EMBASE, CINAHL, PsycINFO, and ASSIA, from January 1996 to June 2020. RESULTS: A total of 17 qualitative (n = 10) and quantitative (n = 7) studies were included in the review. The most commonly reported general and immigrant-specific factors appearing in studies were undocumented immigration status, HIV stigma, homophobia, cultural norms, values and beliefs, family and social support, language barriers, structure, complexity and quality of the U.S. healthcare delivery system, and patient-provider relationship. CONCLUSION: These findings highlight the importance of considering immigrant-specific factors along with general factors to improve the provision of HIV care services and HIV care outcomes among LAC immigrant populations.

Development and Validation of Vulnerable and Enabling Indices for HIV Viral Suppression among People with HIV Enrolled in the Ryan White Program.

BACKGROUND: Numerous factors impact HIV care, often requiring consideration of indices to prevent collinearity when using statistical modeling. Using the Behavioral Model for Vulnerable Populations, we developed vulnerable and enabling indices for people living with HIV (PLWH). METHODS: We used Ryan White Program (RWP) data and principal component analysis to develop general and gender- and racial/ethnic-specific indices. We assessed internal reliability (Cronbach's alpha), convergent validity (correlation coefficient), and predictive utility (logistic regression) with non-viral suppression. RESULTS: Three general factors accounting for 79.2% of indicators' variability surfaced: mental health, drug use, and socioeconomic status (Cronbach's alpha 0.68). Among the overall RWP population, indices showed convergent validity and predictive utility. Using gender- or racial/ethnic-specific indices did not improve psychometric performance. DISCUSSION: General mental health, drug use, and socioeconomic indices using administrative data showed acceptable reliability, validity, and utility for non-viral suppression in an overall PLWH population and in gender- and racial/ethnic-stratified populations. These general indices may be used with similar validity and utility across gender and racial/ethnic diverse populations.

Pre- and Post-immigration HIV Testing Behaviors among Young Adult Recent Latino Immigrants in Miami-Dade County, Florida.

HIV testing early in the immigration process can facilitate timely linkage to HIV prevention and treatment services for immigrants. This study aims to determine the prevalence of self-report HIV testing pre- and post-immigration and the associations between pre-immigration HIV sexual risk behaviors, access to healthcare post-immigration, and HIV testing post-immigration among young adult recent Latino immigrants. Cross-sectional data from 504 recent Latino immigrants aged 18 to 34 who immigrated to Miami-Dade County, Florida during the 12 months before assessment were analyzed using robust Poisson regression models. We found that 23.8% of participants reported HIV testing post-immigration and 56.7% reported HIV testing pre-immigration. The prevalence ratio for post-immigration HIV testing was higher for participants that had health insurance (adjusted prevalence ratio [aPR]: 1.70, 95% confidence interval [CI]: 1.21-2.38) and a regular doctor or healthcare provider after immigration (aPR: 1.43, 95% CI 1.03-2.00), and post-immigration HIV testing was higher for participants that had ever been tested for HIV before immigration (aPR: 2.41, 95% CI 1.68-3.45). Also, the prevalence ratio was lower for those who engaged in condomless sex in the three months prior to immigration (aPR: 0.65, 95% 0.47-0.90). These findings suggest that addressing barriers to healthcare and prevention services for young adult recent Latino immigrants is needed to scale-up HIV testing in this population early in the immigration process.

RESUMEN: Obtener una prueba del VIH al inicio del proceso de inmigración puede facilitar una conexión inmediata con los servicios de prevención y tratamiento del VIH. Este estudio tiene como propósito determinar la prevalencia auto informada de las pruebas de VIH antes y después de la inmigración, y las asociaciones entre las conductas sexuales de riesgo antes de la inmigración, el acceso a los servicios médicos después de la inmigración y las pruebas de VIH realizadas después de la inmigración en Latinos jóvenes adultos recién llegados a los Estados Unidos. Los datos transversales de 504 inmigrantes Latinos recién llegados entre los 18 y 34 años, que inmigraron al condado de Miami-Dade, Florida, durante los 12 meses anteriores a la evaluación, se analizaron utilizando modelos de regresión de Poisson robustos. Encontramos que 23.8% de los participantes informaron haberse realizado la prueba del VIH después de la inmigración y 56.7% informaron haberse realizado la prueba del VIH antes de la inmigración. El índice de prevalencia para las pruebas del VIH después de la inmigración fue mayor para los participantes que tenían seguro médico [índice de prevalencia ajustado (IPa): 1.70, intervalo de confianza (IC) del 95%: 1.21-2.38] y un médico o proveedor regular de atención médica después de la inmigración [IPa: 1.43, IC del 95%: 1.03-2.00], y para los participantes que se habían hecho la prueba del VIH antes de la inmigración [IPa: 2.41, IC de 95%: 1.68-3.45]. Además, el índice de prevalencia fue menor para aquellos participantes que tuvieron relaciones sexuales sin condón en los tres meses previos a la inmigración [IPa: 0.65, IC del 95%: 0.47-0.90]. Estos resultados sugieren que es necesario abordar las barreras a los servicios médicos y de prevención en los inmigrantes Latinos jóvenes adultos recién llegados a los Estados Unidos para ampliar las pruebas del VIH en esta población al inicio del proceso de inmigración.

A qualitative study of antiretroviral therapy adherence interruptions among young Latino men who have sex with men with HIV: Project D.A.I.L.Y.

Consistent antiretroviral therapy (ART) adherence is necessary for HIV viral suppression. However, adherence may fluctuate around daily routines and life events, warranting intervention support. We examined reasons for ART adherence interruptions, using in-depth, semi-structured qualitative interviews, among young (18-34-year-old) Latino men who have sex with men (YLMSM) with HIV. Interviews (n = 24) were guided by the Theory of Planned Behavior, the Information-Motivation-Behavioral Skills Theory, and the Socio-Ecological Model. Two coders independently coded transcripts using NVivo 12 software and synthesized codes into themes using Thematic Content Analysis. Results suggested 4 primary influences on ART adherence interruptions: (1) HIV diagnosis denial, (2) breaks in daily routine, (3) substance use, and (4) HIV status disclosure. Participant quotes highlighted routinization of pill-taking and planning ahead for breaks in routine as critically important. The narrative suggested modification of pill-taking routines during alcohol use, and that periods most vulnerable for long-term interruptions in ART adherence were following an HIV diagnosis and during periods of drug use. Support at the time of HIV diagnosis, including a plan for routinization of pill taking, and adaptive interventions incorporating real-time support during breaks in routines and substance use episodes may be one way to help YLMSM adhere to ARTs.

HIV testing intentions and cognitive reappraisal among Latino emerging adults.

Negative emotions related to HIV testing may influence an individual's intentions to test for HIV. However, emotion regulation strategies such as cognitive reappraisal which involves reframing the meaning of an event to modify one's emotional response to it may potentially help to regulate these emotions and facilitate decisions to get tested for HIV. In this exploratory study, we examined the association between cognitive reappraisal and HIV testing intentions and whether this association differs by gender. Cross-sectional data were collected from a convenience sample of 157 Latino emerging adults aged 18-25 years living in Arizona and Florida through an online survey. Hierarchical logistic regression models were used to analyze the data. Results indicated that cognitive reappraisal was significantly associated with HIV testing intentions (aOR: 1.44, 95% CI:1.04-1.99) and that this association was specific to females (aOR: 2.48, 95% CI: 1.39-4.43). Our results demonstrate the potential of cognitive reappraisal to facilitate HIV testing intentions among females. HIV prevention interventions should incorporate cognitive reappraisal training to regulate and adapt to the negative emotions associated with HIV testing in efforts to increase HIV testing.

Psychosocial stress, bicultural identity integration, and bicultural self-efficacy among Hispanic emerging adults.

Most studies on psychosocial stress among Hispanics have focused on risk factors. To better understand psychosocial stress among this population, this study aimed to examine components of bicultural identity integration and bicultural self-efficacy, that may be associated with lower psychosocial stress among Hispanic emerging adults (ages 18-25). This aim was tested on a cross-sectional sample of Hispanic emerging adults (Mage = 21.30, SD = 2.09) that included 200 participants (Arizona n = 99, Florida n = 101). The sample included men (n = 98) and women (n = 102). Most participants were US-born (70%), college students (69.5%), and of Mexican heritage (44%). Standardized coefficients from a hierarchical multiple regression model indicate that higher levels of the bicultural harmony component of bicultural identity integration (ß = -0.26, p < 0.001) and the social groundedness component of bicultural self-efficacy (ß = -0.23, p < 0.01) were associated with lower levels of psychosocial stress. To our knowledge, this is the first study to examine components of bicultural identity integration and bicultural self-efficacy and their respective associations with psychosocial stress among any racial/ethnic group. Thus, more studies are needed to replicate our findings to determine if bicultural identity integration and bicultural self-efficacy should be considered in psychosocial stress interventions for Hispanics.

Depression and Gender Roles among Hispanic Immigrant Women: Examining Associations of Gender Egalitarianism, Marianismo, and Self-Silencing.

Background: Efforts in the prevention and treatment of depression among Hispanic immigrant women require studies to identify modifiable factors of depression. Some factors that may merit investigation are gender roles such as egalitarian gender attitudes, marianismo, and self-silencing. Methods: This cross-sectional study included 231 Hispanic immigrant women living in Miami-Dade County, Florida. Logistic regression was used to examine associations of covariates, egalitarian gender attitudes, marianismo, and self-silencing in relation to depression. Results: Egalitarian gender attitudes were not associated with depression. For marianismo domains, higher scores on the spiritual pillar scale were associated with lower odds of depression. With regard to self-silencing, higher scores on externalizing self-perception and divided self were associated with higher odds of depression. Conclusions: Findings add to the limited literature on depression among Hispanic immigrants and provides some insight on sociocultural factors that may be considered in depression interventions for Hispanic immigrant women.

Alcohol use severity among Hispanic emerging adults: Examining the roles of bicultural self-efficacy and acculturation.

OBJECTIVE: This study aimed to (1) examine respective associations of acculturation orientations (e.g., U.S. orientation and Hispanic orientation) and domains (e.g., social groundedness and role repertoire) of bicultural self-efficacy, the perceived confidence to function effectively within the receiving culture and the heritage culture, with alcohol use severity among Hispanic emerging adults. This study also aimed to (2) examine potential moderating factors of respective associations among acculturation orientations and bicultural self-efficacy with alcohol use severity. METHOD: 200 Hispanic emerging adults from Arizona (n = 99) and Florida (n = 101) completed a cross-sectional survey. Inclusion criteria were being ages 18-25, self-identify as Hispanic or Latina/o, and currently living in Maricopa County or Miami-Dade County. Data were analyzed using hierarchical multiple regression and moderation analyses. RESULTS: Findings indicate that neither of the acculturation orientations nor role repertoire had main effects with alcohol use severity. However, higher social groundedness was associated with lower alcohol use severity. Moderation analyses indicate that the interaction between the U.S. orientation and study site and the interaction between the Hispanic orientation and social groundedness were statistically significant in relation to alcohol use severity. CONCLUSIONS: Considering that the U.S. orientation was associated with alcohol use severity only in Arizona highlights the need for multisite studies on acculturation. Our findings demonstrate that other sociocultural processes such as acculturation can impact bicultural self-efficacy; and that the association between bicultural self-efficacy and alcohol merits further investigation. However, more thorough assessments of bicultural self-efficacy are needed to better understand its effects on alcohol.

Self-efficacy and HIV testing among Latino emerging adults: examining the moderating effects of distress tolerance and sexual risk behaviors.

Latino emerging adults in the United States are at a high risk of HIV and have a low prevalence of HIV testing. This study examined the association between self-efficacy for HIV testing, distress tolerance and lifetime history of HIV testing, and tested the moderating effect of distress tolerance and sexual risk behaviors on the association between self-efficacy and lifetime history of HIV testing. Data were collected from a cross-sectional sample of 157 Latino emerging adults aged 18-25 using an online survey and were analyzed using hierarchical logistic regression and moderation analyses. We found that 62.8% of those engaging in sexual risk behaviors had ever been tested for HIV. Participants that reported higher levels of self-efficacy (aOR=3.49, 95%CI: 1.78-6.83) were more likely to have ever been tested for HIV in their lifetime. There was a statistically significant three-way interaction among self-efficacy for HIV testing, distress tolerance and sexual risk behaviors (b=2.76, 95%CI: .52, 5.00, p=.016). This interaction suggests that among those that reported any sexual risk behaviors, higher levels of self-efficacy were associated with lifetime history of HIV testing only at higher levels of distress tolerance. Further research is warranted to determine how self-efficacy and distress tolerance work together among high-risk groups to promote HIV testing.

HIV Testing Among Latino Emerging Adults: Examining Associations with Familism Support, Nativity, and Gender.

Research examining factors associated with low uptake of HIV testing among Latino emerging adults is scarce. Thus, this study examined the association between familism support and lifetime history of HIV testing among Latino emerging adults, and whether nativity status and gender moderated this association. A cross-sectional online survey of 157 Latino emerging adults aged 18-25 years living in Arizona and Florida was conducted and data were analyzed using robust Poisson regression models. Results indicated that 59.9% of participants reported a lifetime history of HIV testing. Higher familism support was associated with a decreased prevalence of lifetime history of HIV testing (aPR = 0.81, 95% CI: 0.68- 0.95). Nativity status moderated the association between familism support and lifetime history of HIV testing, with this negative association, only found among immigrants (aPR = 0.46, 95% CI: 0.28-0.74). Gender did not moderate this association. Familism support plays a role in HIV testing behaviors, and thus should be considered when developing programs to increase HIV testing among Latinos.

Depressive Symptoms and Resilience among Hispanic Emerging Adults: Examining the Moderating Effects of Mindfulness, Distress Tolerance, Emotion Regulation, Family Cohesion, and Social Support.

Emerging adulthood has been described as a difficult stage in life and may be particularly stressful for Hispanic emerging adults who are disproportionately exposed to adversity and chronic sociocultural stressors. To better prevent and treat depressive disorders among Hispanic emerging adults, more research is needed to identify and understand modifiable determinants that can help this population enhance their capacity to offset and recover from adversity and sociocultural stressors. As such, this study aimed to (1) examine the association between resilience and depressive symptoms among Hispanic emerging adults, and (2) examine the extent to which intrapersonal resources (e.g., mindfulness, distress tolerance, emotion regulation strategies) and interpersonal resources (e.g., family cohesion, social support) moderate the association between resilience and depressive symptoms. To examine these aims, 200 Hispanic emerging adults (ages 18-25) from Arizona (n = 99) and Florida (n = 101) completed a cross-sectional survey, and data were analyzed using hierarchical multiple regression and moderation analyses. Findings from the hierarchical multiple regression indicate that higher resilience was associated with lower depressive symptoms. Findings from the moderation analyses indicate that family cohesion, social support, and emotion regulation strategies (e.g., cognitive reappraisal and expressive suppression) functioned as moderators; however, mindfulness and distress tolerance were not significant moderators. Findings from this study add to the limited literature on resilience among Hispanics that have used validated measures of resilience. Furthermore, we advance our understanding of who may benefit most from higher resilience based on levels of intrapersonal and interpersonal resources.

Testing the Efficacy of an HIV Prevention Intervention Among Latina Immigrants Living in Farmworker Communities in South Florida.

Latina immigrants living in farmworker communities are a population in need of HIV risk reduction interventions due to their high risk for HIV and their limited access to health care and prevention services. The present study is the first to evaluate the efficacy of SEPA intervention on a cohort of 234 pre-established Latina immigrants living in farmworker communities in South Florida. SEPA is a CDC evidenced-based and Latinx culturally tailored HIV risk reduction intervention. Data were collected through structured interviews at baseline and 6-months post intervention and were analyzed using generalized linear mixed modeling. Results showed that SEPA was effective on increasing condom use during vaginal and anal sex with male partners, self-efficacy for condom use, intentions to negotiate safe sex and HIV-related knowledge from baseline to 6-months post intervention. These findings contribute to the evidence supporting the efficacy of SEPA by confirming previous results and demonstrating the efficacy of this intervention for Latinas of diverse backgrounds.

Continued Medical Waste Exposure of Recyclable Collectors Despite Dumpsite Closures in Brazil.

BACKGROUND: Brasilia, the capital of Brazil, currently has the largest dumpsite of the Americas at Estrutural, with over 30 million tons of waste accumulated. Recyclable waste collectors are a group of workers who, in addition to having a low socioeconomic status and residing in vulnerable areas, work sorting garbage in inadequate and unsanitary areas. This profession puts individuals at risk, resulting in death, mutilation, and disease for workers. OBJECTIVES: The aim of this study was to understand the effects of waste on recyclable collectors, along with their perceptions of associated risks. METHODS: A qualitative study was conducted, using interviews with 34 participants at Estrutural. RESULTS: Collectors were exposed to several hazards, including biological, physical, and more extreme hazards (e.g. being run over by waste trucks). Personal protective equipment was not adequately used, exposing recyclable collectors to injury. Accidents included cuts, burns, skin lesions, eyes lesions, and arm, leg, head, feet, and hand injuries and amputations. Often, homecare remedies and collected medical waste (e.g. pain killers) were used on these injuries instead of seeking out proper medical care. CONCLUSIONS: Recyclable collectors were aware of occupational hazards, but lacked education on the risks and consequences associated with exposure to medical hazards. Moreover, Brazil recently formally closed all dumpsites, complicating this issue. The findings of the present study confirm the need to address these hazards to provide a safe working environment for waste pickers. PARTICIPANT CONSENT: Obtained. ETHICS APPROVAL: This study was approved by the Research and Ethics Committee of the Health School of Brasília University under Opinion n. 1.517.670/2016. COMPETING INTERESTS: The authors declare no competing financial interests.

Efficacy of a school-based intervention to bring awareness about PCB contamination and exposure avoidance in Guánica, Puerto Rico.

Production of polychlorinated biphenyls (PCB) was banned in the US in 1970s. However, susceptible populations especially those living at/around the contaminated sites continue to be at a risk of elevated exposure to PCBs because information about the contamination (of the environment) and its associated health risks may not reach these populations. A recent study found the second highest concentration of PCBs ever recorded worldwide in the sediment samples of Guánica Bay, located in the southwestern part of Puerto Rico. PCB levels in fish from the bay were also higher than the tolerance limit of Food and Drug Administration (FDA), which motivated this research to initiate a school-based campaign to bring community awareness about the contamination of the bay and engage students in preventive strategies to reduce their exposure to PCBs. Surveys before and after the campaign were administered in the high school as well as in the communities of Guánica Municipality. The analyses of the survey data suggest that the campaign was effective in bringing awareness among schoolchildren (6.6% before versus 69.7% after the campaign; χ2 ~ 60.4; p < 0.001) and strategies to reduce PCB exposure and its toxicity such as removing adipose tissues from seafood/fish and exercising. In the community, there was a significant decline in the consumption of seafood/fish harvested from the bay after the campaign (54.6% before versus 33% after the campaign; χ2 ~ 10.85; p < 0.001). However, the awareness did not result in significant behavior modifications among schoolchildren, such as avoiding swimming and fishing in the bay. Given hazardous levels of PCBs and some students use the bay for various purposes, including one-third of community members still use seafood/fish harvested from the bay, attention of different stakeholders is warranted for clean-up efforts as well as engaging children and communities in PCB exposure avoidance strategies.

Associations of Self-Silencing and Egalitarian Attitudes with HIV Prevention Behaviors Among Latina Immigrant Farmworkers.

Latinas in farmworker communities are at particularly higher risk for human immunodeficiency virus (HIV) due to the vulnerable circumstances they experience. However, little is known about the factors influencing HIV prevention behaviors in this population. The aim of this study was to examine the associations of self-silencing behaviors and egalitarian attitudes toward women in relation to three HIV prevention behaviors: self-efficacy for HIV prevention, intentions to negotiate safe sex, and HIV-related knowledge. This study is a cross-sectional analysis that used hierarchical multiple regression models to examine these previously mentioned associations, among Latina immigrant farmworkers from Miami-Dade County, Florida (n = 232). Findings indicated that self-silencing behaviors were adversely associated with the three HIV preventive behaviors whereas egalitarian attitudes were positively associated. Findings from this study may help to advance the understanding of sociocultural determinants of HIV prevention behaviors among Latina immigrants.
