Adverse childhood experiences among black sexually minoritized men and Black transgender women in Chicago.

BACKGROUND: Adverse childhood experiences (ACE) are important predictors of mental health outcomes in adulthood. However, commonly used ACE measures such as the Behavioural Risk Factor Surveillance System (BRFSS) have not been validated among Black sexually minoritized men (SMM) nor transgender women (TW), whom are known to have higher rates of ACE and poorer mental health outcomes. Assessing the psychometric properties of the measure is important for health equity research, as measurements that are not valid for some populations will render uninterpretable results. METHODS: Data are drawn from the Neighborhoods and Networks (N2) study, a longitudinal cohort of Black SMM and TW living in Southern Chicago. We conducted confirmatory factor analysis, correlation analysis and a two-parameter Item Response Theory (IRT) on the BRFSS ACE measure, an 11-item measure with 8 domains of ACE. RESULTS: One hundred forty seven participants (85% cisgender male) completed the BRFSS ACE measurement in the N2 study with age ranges from 16-34. The cohort were from a low socioeconomic background: about 40% of the cohort were housing insecure and made than $10,000 or less annually. They also have a high number of ACEs; 34% had endorsed 4 or more ACE domains. The three-factor structure fit the BRFSS ACE measure best; the measurement consisted of three subscales: of "Household Dysfunction", "Emotional / Physical", and "Sexual Abuse" (CFI = 0.975, TLI = 0.967, and RMSEA = 0.051). When the 8 domains of ACE were summed to one score, the total score was is correlated with depressive symptoms and anxiety scores, establishing concurrent validity. Item Response Theory model indicated that the "parental separation" domain had a low discrimination (slope) parameter, suggesting that this domain does not distinguish well between those with and without high ACE. CONCLUSIONS: The BRFFS ACE measure had adequate reliability, a well-replicated structure and some moderate evidence of concurrent validity among Black SMM and TW. The parental separation domain does not discriminate between those with high and low ACE experiences in this population. With changing population demographics and trends in marriage, further examination of this item beyond the current study is warranted to improve health equity research for all.

Neighborhood violent crime exposure is associated with PrEP non-use among black sexually minoritized men and transgender women: A GPS Study.

OBJECTIVE: The objective of this study is to use GPS technology to determine if violent and property crime exposure to participants activity spaces affect outcomes of the HIV prevention and care continuum (PCC) among Young Black sexually minoritized men (YBSMM) and Transgender women (TW), a subgroup at high vulnerability for new HIV diagnoses. Exposure to violent and property crime adversely affects a variety of acute and chronic medical conditions; however the relationship between exposure to violent and property crime and HIV risk (e.g., PrEP non use) is unknown. Spatial analytic analysis using dynamic Global Position Systems (GPS) technology can accurately detect geospatial associations between the crime exposure and objective HIV related outcomes. METHODS: With the Neighborhoods and Networks (N2) Cohort Study, GPS technology to identify the activity space of 286 (123 PLWH and 163 PWoH) YBSMM & TW living in Chicago, IL, to identified spatial associations between violent and property crime exposures with HIV PCC outcomes. RESULTS: We found that YBSMM & TGW with higher exposure areas with higher levels of violent crime were less likely to use HIV preexposure prophylaxis (PrEP) therapy (aOR 0.76, 95% CI 0.63-0.91, p = 0.03). CONCLUSION: This study demonstrates the importance of clinical providers to consider violent crime as a potential sociostructural barrier that may impact medication adherence and health care outcomes among vulnerable populations. Additionally, GPS technology offers an alternative data analytic process that may be used to future studies to assist in identifying barriers to ending the HIV epidemic.

PROGRESO-II: Developing Culturally Tailored Materials for a Social Network-Based Intervention to Promote HIV Pre-Exposure Prophylaxis Initiation Among Latina Seasonal Farmworkers.

Latina Seasonal Farmworkers (LSFW) in South Florida are a community affected by human immunodeficiency virus (HIV) due to cultural barriers, stigma, and lack of awareness of pre-exposure prophylaxis (PrEP). Building on the PROGRESO study, this study sought to: (1) develop and pre-test scientifically supported and culturally tailored PrEP materials for PROGRESO and (2) assess the acceptability of these PrEP materials by LSFW who use alcohol and/or drugs. PrEP messages were selected based on a literature review, feedback from experts working on PrEP programs, and recommendations from a four-member scientific expert panel through a two-level Delphi method. A culturally tailored PrEP presentation was developed and presented to sixteen LSFW, who engaged in four focus groups. Materials were modified based on participants' suggestions. Thematic analysis was used to assess the acceptability and usability of these materials in the LSFW community. Participants responded positively to the PrEP messages and understood their importance for Latinx communities. Participants felt empowered and comfortable enough with the information to distribute the messages to partners, children, and friends with the aid of a physical pamphlet or flyer. A strong cultural context of familialismo and confianza was present in comments made by our participants. This study has the potential to increase LSFW's PrEP awareness and initiation. Future studies may implement a hybrid-interview approach, allowing individuals to self-select into a virtual or in-person focus group. Such flexibility may increase participation and discussion by allowing participants to attend in a format they are most comfortable with, as noted by participants in this study.

A Network Science Approach to Sex-Polydrug Use Among Black Sexually Minoritized Men and Transgender Women: The N2 Cohort Study.

Black sexually minoritized men (SMM) and transgender women (TW) are subgroups with lower rates of substance use and comparable rates of condom use relative to White SMM and TW yet experience heightened vulnerability to HIV. This study sought to explore associations of substance use, including sex-drug use (i.e., drug or alcohol use during sex to enhance sex), and condomless sex among Black SMM and TW. Data were collected from Black SMM and TW living in Chicago, Illinois, enrolled in the Neighborhoods and Networks (N2) cohort study, from November 2018 to April 2019. We used bivariate analyses followed by a multilevel egocentric network analysis to identify factors associated with condomless sex. We conducted Spearman correlation coefficients to examine correlations between pairs of sex-drugs to enhance sex. We used a bipartite network analysis to identify correlates of sex-drug use and condomless sex. A total of 352 Black SMM and TW (egos) provided information about 933 sexual partners (alters). Of respondents, 45% reported condomless sex and 61% reported sex-drug use. In unadjusted analyses, marijuana (34%) and cocaine/crack (5%) sex-drug use were associated with condomless sex (p < 0.05). Condomless sex was positively associated with sex-polydrug use, or the use of 2+ drugs or 1 drug and alcohol (OR = 1.48; 95% CI: 1.02-2.14; p = 0.039), and negatively associated with sharing an HIV-negative serostatus with a sexual partner (OR = 0.57; 95% CI: 0.33-0.98; p = 0.041), having a different HIV serostatus with a sexual partner (OR = 0.37; 95% CI: 0.21-0.64; p < 0.001) or not knowing the HIV serostatus of a sexual partner (OR = 0.47; 95% CI: 0.26-0.84; p = 0.011). The following pairs of sex-polydrug use had Spearman correlation coefficients higher than 0.3: marijuana and alcohol, ecstasy and alcohol, cocaine/crack and ecstasy, and methamphetamine and poppers (p < 0.05). HIV prevention interventions for Black SMM and TW designed to reduce HIV transmission through egocentric sexual networks could address sex-drug use through sex-positive and pleasure-centered harm reduction strategies and provide and promote biomedical prevention and care options at supraoptimal levels.

Patterns of Polydrug Use Classes Among a Subset of Latino Male Seasonal Workers in South Florida: A Latent Class Analysis.

BACKGROUND: Little is known about polydrug use among Latino seasonal farmworkers. This cross-sectional study with male Latino seasonal workers (LSWs) living in South Florida categorized distinct classes of drug use and then characterized each drug use typology by demographic, structural, and psychological factors. METHODS: One hundred and twenty-five male LSWs were recruited during community events using convenience sampling between July 2019-March 2020. Latent class analysis was conducted by leveraging measures of self-reported use of nine drugs in the past year (sedatives, cannabis, stimulants, heroin, opioids, cocaine, PCP, hallucinogens, and inhalants). Correlates of latent class membership were examined using 3-step categorical latent variable logistic regression. Analyses were performed using Mplus version 8 and SAS 9.4. RESULTS: Four drug use classes were identified, male LSWs who exhibited: 1) use of illegal opioids only (n = 32); 2) concurrent cannabis and cocaine use (n = 75); 3) concurrent sedative and cannabis use (n = 13); and 4) high concurrent drug use (n = 5). About 84.7% of the sample reported use of at least one drug in the past 12 months. LSWs who identified as White and were married or in a stable relationship were likely to only use illegal opioids. LSWs with less than high school education and self-reported good to excellent health were more likely to use cannabis and cocaine. Men with moderate to severe anxiety and self-reported bad health were classified as engaging in sedative and cannabis co-use. Survivors of physical abuse were more commonly classified as people using high concurrent substances relative to non-abused men among the four classes. CONCLUSIONS: This pilot study suggests the presence of heterogeneity in polydrug use classes among LSWs in South Florida.

Latent Profile Patterns of Network-Level Norms and Associations with Individual-Level Sexual Behaviors: The N2 Cohort Study in Chicago.

Individual-level behavior can be influenced by injunctive and descriptive social network norms surrounding that behavior. There is a need to understand how the influence of social norms within an individual's social networks may influence individual-level sexual behavior. We aimed to typologize the network-level norms of sexual behaviors within the social networks of Black sexual and gender minoritized groups (SGM) assigned male at birth. Survey data were collected in Chicago, Illinois, USA, between 2018 and 2019 from Black SGM. A total of 371 participants provided individual-level information about sociodemographic characteristics and HIV vulnerability from sex (i.e., condomless sex, group sex, use of alcohol/drugs to enhance sex) and completed an egocentric network inventory assessing perceptions of their social network members' (alters') injunctive and descriptive norms surrounding sexual behaviors with increased HIV vulnerability. We used Latent Profile Analysis (LPA) to identify network-level norms based on the proportion of alters' approval of the participant engaging in condomless sex, group sex, and use of drugs to enhance sex (i.e., injunctive norms) and alters' engagement in these behaviors (i.e., descriptive norms). We then used binomial regression analyses to examine associations between network-level norm profiles and individual-level HIV vulnerability from sex. The results of our LPA indicated that our sample experienced five distinct latent profiles of network-level norms: (1) low HIV vulnerability network norm, (2) moderately high HIV vulnerability network norm, (3) high HIV vulnerability network norm, (4) condomless sex dominant network norm, and (5) approval of drug use during sex dominant network norm. Condomless anal sex, group sex, and using drugs to enhance sex were positively and significantly associated with higher HIV vulnerability social network norm profiles, relative to low HIV vulnerability norm profiles. To mitigate Black SGM's HIV vulnerability, future HIV risk reduction strategies can consider using network-level intervention approaches such as opinion leaders, segmentation, induction, or alteration, through an intersectionality framework.

Sociodemographic Correlates of Affordable Community Behavioral Health Treatment Facility Availability in Florida: A Cross-Sectional Study.

Behavioral health disorders such as mental disorders (MD) and substance use disorders (SUD) are epidemics in the US; however, the availability of treatment and prevention services remains low. This study assessed neighborhood-level sociodemographic attributes to characterize the availability of behavioral health treatment facilities in Florida. The American Community Survey and SAMHSA's Behavioral Health Treatment Locator were used to identify behavioral health treatment facilities in Florida and calculate their density by census tract. Spatial lag regression models were used to assess census tract-level correlates of facility density for 390 MD treatment facilities, 518 SUD facilities, and subsets of affordable MD and SUD facilities. Behavioral health treatment facility density was negatively associated with rurality and positively associated with the proportion of non-Latino Black, Latino, insured, and college-educated populations. Stark rural-urban disparities in behavioral health treatment availability present opportunities to prioritize telehealth and mobile interventions and improve treatment utilization.

Network-level HIV risk norms are associated with individual-level HIV risk and harm reduction behaviors among people who inject drugs: a latent profile analysis.

The COVID-19 related U.S.-Mexico border-crossing restrictions disrupted social networks and HIV harm reduction services among people who inject drugs (PWID) in San Diego and Tijuana. We assessed associations of descriptive network norms on PWID's HIV vulnerability during this period. Between 10/2020 and 10/2021, 399 PWID completed a behavioral and egocentric questionnaire. We used Latent Profile Analysis to categorize PWID into network norm risk profiles based on proportions of their network (n = 924 drug use alters) who injected drugs and engaged in cross-border drug use (CBDU), among other vulnerabilities. We used logistic and linear regressions to assess network profile associations with individual-level index of HIV vulnerability and harm reduction behaviors. Fit indices specified a 4-latent profile solution of descriptive network risk norms: lower (n = 178), moderate with (n = 34) and without (n = 94) CBDU and obtainment, and higher (n = 93). Participants in higher risk profiles reported more HIV vulnerability behaviors and fewer harm reduction behaviors. PWID's gradient of HIV risk was associated with network norms, warranting intervention on high-vulnerability networks when services are limited.

Life Instability Associated with Lower ART Adherence and Other Poor HIV-Related Care Outcomes in Older Adults with HIV.

BACKGROUND: Life instability may be an important factor for HIV-related care outcomes in older adults living with HIV (OALWH). This study examined the degree to which an 11-item life instability index (LII) composed of individual- and community-level indicators was associated with HIV-related care outcomes-viral load, antiretroviral (ART) medication adherence, rates of detectable viral load, and HIV care appointment non-adherence among OALWH in the Miami area. METHODS: Six hundred twenty-three OALWH completed an interviewer-administered assessment (English or Spanish), which was matched with medical record data. RESULTS: Participants reported about six LII indicators each (M = 6.08, SD = 1.44). Greater index scores were associated with worse self-reported ART adherence (b = - 1.14, p = 0.03), lower observed appointment adherence (b = 0.02, p < 0.01), higher viral load (b = 0.09, p = 0.02), and greater odds of viral detection (OR = 1.22, p = 0.01). Regarding health behaviors, life instability was significantly associated with increased illicit substance use among participants and not associated with depression or anxiety. The association of life instability to ART adherence remained significant (although attenuated) when controlling for the significant effects of substance use (b = - 0.40, BSTP [- 0.87, - 0.09]). CONCLUSION: This present study is the first to examine an additive life instability index and its association with HIV-related behavioral and biomedical health outcomes among a population of OALWH. Greater indicators of life instability among OALWH may lead to poorer HIV-related health outcomes above and beyond the net of the effects of depression, anxiety, and substance use.

Geographic Disparities in Availability of Spanish-Language PrEP Services Among Latino Sexual Minority Men in South Florida.

Latino sexual minority men (LSMM) experience barriers in accessing HIV pre-exposure prophylaxis (PrEP), such as lack of proximate culturally-appropriate PrEP navigation services. We examined associations between LSMM's immigration status and Spanish-language PrEP service availability. LSMM clinically indicated for PrEP were recruited from October 2018 to August 2019 in South Florida and completed an interviewer-administered questionnaire. PrEP service navigators in South Florida were identified using the CDC PrEP Directory. We constructed network service areas of 1-, 2-, and 5-miles from Spanish-speaking PrEP navigators. We used multilevel logistic regression to examine associations of individual (i.e., age, income, immigration status, network density) and zip code-level (i.e., population density, poverty, HIV risk) measures with availability of Spanish-language PrEP navigation services. A total of 131 participants clustered into 60 zip codes in South Florida. Latin American-born LSMM reported higher immigration and discrimination stress, and were 91% less likely to have PrEP navigation service availability, relative to LSMM born in the US. Zip code-level HIV incidence was associated with higher service availability within a 1-mile network of Spanish-speaking PrEP navigators. Spanish-language PrEP navigation services were available in high-HIV incidence zip codes; however, Latin American-born LSMM experienced reduced availability. Immigration and discrimination stress may explain lack of availability.

Binge Drinking Moderates Unprotected Sex Among HIV Sero-Similar Same Sex Male Couples: An Actor-Partner Interdependence Model.

Most new HIV diagnoses in the US occur among sexual minority men (SMM). The majority (69%) of new HIV diagnoses among US SMM are due to transmission from main sex partners. We identified multilevel correlates of unprotected anal intercourse (UAI; condomless anal intercourse while not using a biomedical strategy) among SMM couples using the Actor Partner Interdependence Model (APIM). Participants were US SMM over 18 years, with a primary male partner > 6 months. Couples were recruited online from April 2016 until June 2017 and interviewed using self-administered computer-assisted surveys. We used a series of APIM regressions to assess multilevel associations with UAI. We also tested the moderating role of an individual's binge drinking on the relationship between HIV status similarity and UAI. Among 798 participants (n = 411 couples), 61% reported UAI in the past 6 months. Binge drinking (52%) and physical intimate partner violence (IPV; 34%) were considerably high within our sample. Actor's binge drinking, reporting experiencing and/or perpetrating physical IPV, and partner's trust were positively associated with UAI. Actor having other sexual partner(s), using illegal drugs (not marijuana), and length of relationship were negatively associated with UAI. Binge drinking positively moderated UAI among HIV serostatus similar partners. HIV prevention programming should integrate components on IPV and binge drinking reduction- especially among HIV serostatus similar couples.

Associations between living arrangement and sexual and gender minority stressors among university students since the start of the COVID-19 pandemic.

OBJECTIVE: To examine the associations between COVID-19-related living arrangements and sexual and gender minority (SGM)-related stressors (ie, identity concealment and familial rejection). PARTICIPANTS: N = 478 SGM university students (Mage = 22 years, SD = 4.00). METHODS: SGM university students were surveyed cross-sectionally between May and August 2020 regarding SGM-related stressors and living arrangements since the start of COVID-19. RESULTS: Approximately half (48.7%) of the sample reported a living rearrangement to their parents' home due to COVID-19. Living rearrangement to parents' homes was associated with an increased degree of identity concealment (ß [95% C.I.] = 0.62 [0.10, 1.15]; p = .020) and familial rejection (ß [95% C.I.] = 1.56 [0.72, 2.41]; p < .001) since the start of COVID-19 compared to stably living without parents (34.3%). Stably living with parents (17.0%) was not associated with increased degree of SGM-related stressors compared to experiencing a living rearrangement. CONCLUSIONS: Stakeholders must consider the unique identity-related vulnerabilities of SGM students living with parents and who experience living rearrangements due to COVID-19.

Feasibility and Acceptability of HIV Self-Test Kit Distribution Through PrEP Clients' Social and Sexual Networks to Increase HIV Testing and PrEP Information.

OBJECTIVE: To determine the feasibility, acceptability, and implementation of a HIV self-test (HIVST) program through PrEP clients' social and sexual networks. BACKGROUND: HIV testing is critical for treatment and prevention engagement. HIVST kits can overcome barriers to testing. A negative result is an opportunity to provide PrEP information. We describe implementation factors associated with engaging current Mobile PrEP (MP) clients to distribute HIVST kits and PrEP information through their networks. SETTING: Community venues in Miami-Dade County, Florida. METHODS: A baseline survey collected network information and explored distribution plans for offering HIVST kits. A follow-up survey evaluated use and distribution. A logic model describes the process of implementation and evaluation. Up to 4 Ora-Quick HIV ST kits were offered to 81 MP clients. A brief training included resources for posttest engagement. RESULTS: Forty-four percent of the kits were reported as distributed. Of 81 MP clients offered kits, 50 (62%) accepted. In a follow-up survey, 77% of MP clients distributed at least 1 kit. Fifty-six (86%) social network members were Latino, and 9 (14%) were Black. Three of 4 MP clients engaged in PrEP discussions (77%) with SN members. Reported reasons for HIVST kit use included convenience, confidentiality, privacy concerns, and discomfort with going to a testing site. MP clients reported that kit distribution was affected by the COVID-19 pandemic. CONCLUSION: HIV ST kits allowed PrEP users to engage others in their social and sexual networks for HIV testing and information regarding PrEP. Work to scale-up this intervention is underway.

The association between egocentric sexual networks and sexual meeting venues with PrEP conversation and encouragement for use among Latinx men who have sex with men.

Despite the increasing availability of pre-exposure prophylaxis (PrEP), Latinx men who have sex with men (LMSM) are not receiving PrEP-related information. To understand the influence of LMSM sexual networks on PrEP-related conversations and encouragement to use PrEP, this cross-sectional egocentric network study characterized the PrEP-related communication of 130 LMSM egos with 507 sexual partners (alters). Participants were recruited using respondent-driven sampling methods from a Miami-Dade County community-health organization. Egocentric-level data were collected from 2018-2019 and analyzed using multilevel modeling. Of egos, 30% reported using PrEP. Closeness between participants and sexual partners played a role in PrEP conversation and encouragement. Participants believed they would have less success convincing sexual partners to use PrEP if partners were older. Participants perceived higher likelihood to talk about PrEP or success in encouraging alters to use PrEP if, relative to meeting sexual partners on Grindr, they met at a friend's party, gay-centric community event, or school/work. Given that increased closeness and in-person sexual partner meeting venues are associated with PrEP information dissemination and encouragement, social network-based interventions can capitalize on PrEP navigators who run network visualizations, and with this information develop a longitudinal plan to increase PrEP conversation and encouragement as needed for each network.

The Association Between Homophily on Illicit Drug Use and PrEP Conversations Among Latino Men Who Have Sex with Men Friends: A Dyadic Network and Spatially Explicit Study.

Despite the wide availability of PrEP, Latino men who have sex with men (LMSM) continue to experience access barriers. Novel HIV prevention research strategies to increase PrEP uptake and adherence among the high incidence populations, such as LMSM who misuse drugs, include social network analyses. This study identified the associations of drug use homophily within LMSM friendship networks and PrEP promotion conversations and described the physical overlap between geographic drug risk areas with conversations of PrEP promotion. Respondent-driven sampling was used to recruit 10 sociocentric networks. Quadratic assignment procedure (QAP) correlations and multiple regression QAPs were used to identify influences of drug use homophily, and geocoding and visualizations to describe drug use polygons and PrEP conversations. Friendship relationships in which both friends used cocaine or marijuana were more likely to report PrEP-related conversations in the past six months. The likelihood of talking about PrEP in the next six months was higher among dyads with cocaine use homophily and ecstasy use homophily, while lower among dyads with marijuana use homophily. Participants reported using marijuana and cocaine throughout Miami-Dade County while ecstasy polygons were mostly in urban areas. The majority of drug polygons associated with PrEP conversations were located in north and central Miami. Future interventions can consider enrolling entire sociocentric friendship groups, configuring friendship networks to connect those without PrEP information to those with information, and incorporating peer leaders.

COVID-19 Related Racial Discrimination in Small Asian Communities: A Cross Sectional Study.

Since the outbreak of COVID-19, there has been a surge of discrimination against Asians across the globe. However, there is a knowledge gap of COVID-19 related racial discrimination against Asians in smaller Asian populations. A total of 221 adults living in Florida completed an online survey between June-July 2020. Adjusted logistic regression assessed associations between sociodemographic factors and experienced discrimination, hypervigilance of safety, nervousness in public, and anticipated discrimination. Statistical analyses were performed using SPSS. Asian respondents were more likely than non-Asians to experience discrimination during COVID-19 (AOR = 12.58; 95% CI 4.74, 33.38; p ≤ 0.001). Asians were more likely to anticipate discrimination after the pandemic ends (AOR = 4.35, 95% CI 1.33, 14.17; p < 0.05). We found that Asians in smaller Asian populations suffer from a disproportionate level of discrimination due to COVID-19, relative to non-Asians. Our findings support previous research that racial discrimination exists on a continuum of violence and can have severe negative health consequences.

Influences of immigration stress and occupational exploitation on Latina seasonal workers' substance use networks: a qualitative study.

US female Latina seasonal farm workers (LSW) are a medically underserved community experiencing severe health disparities. We explored the relationship between alcohol and prescription medication, and LSW social networks using a qualitative approach. In 2015, this study used convenience sampling to recruit 28 LSWs in South Florida for three focus group discussions in Spanish. Focus groups were translated to English for analysis, which employed a general inductive approach. Themes included prescription medication distribution within networks, spirituality/religion practice with friends and family, and alcohol use with friends. Substance abuse prevention and treatment interventions should account for the unique needs of LSW.

Condom use likelihood within the context of PrEP and TasP among men who have sex with men in Florida: a short report.

Despite the development of targeted interventions for men who have sex with men, this population continues to comprise the majority of new HIV diagnoses. Though condoms are highly efficacious, some sexually active MSM use sero-sorting as a method of HIV prevention. This study aimed to characterize: (1) differences between partner sero-status and condom use likelihood, and (2) demographic, behavioral, and knowledge-related factors influencing condom use likelihood with varying sero-status partners. Using convenience sampling, 150 sexual and gender minority men completed a survey on PrEP and sexual behaviors. The majority of participants identified as racial/ethnic minorities (51.7%), having 4 years of college or more (52.0%), and being HIV-negative (not on PrEP) (68.8%). Our sample reported the lowest average condom use likelihood with a partner on PrEP (2.93 ± 1.39) and the highest average likelihood with an HIV-positive partner (unknown VL) (4.57 ± 0.98). Age, race/ethnicity, education, HIV-status, and HIV and PrEP knowledge were significantly associated with differences in condom use likelihood. Our findings elucidate the complexity of sero-sorting scenarios and decision-making processes in the context of biomedical HIV prevention. These results may provide insight for future condom use and sero-sorting interventions in the context of biomedical HIV prevention.

Why Re-Invent the Wheel? Social Network Approaches Can Be Used to Mitigate SARS-CoV-2 Related Disparities in Latinx Seasonal Farmworkers.

Latinx seasonal farmworkers are essential workers and are at elevated risk for SARS-CoV-2 in the United States. Risk factors for SARS-CoV-2 are unique to this population and include crowded living conditions, isolated social networks, and exploitative working environments. The circumstances and cultural values of Latinx seasonal farmworkers pose a unique challenge to public health authorities working to contain the spread of SARS-CoV-2. This community is in dire need of urgent public health research to identify opportunities to prevent SARS-CoV-2 transmission: social network methods could be the solution. Using previously collected and new information provided by a team of experts, this commentary provides a brief description of Latinx seasonal farmworker disparities that affect tracking and treating SARS-CoV-2 in this important group, the challenges introduced by SARS-CoV-2, and how social network approaches learned from other infectious disease prevention strategies can address these disparities.

The Association Between Social and Spatial Closeness With PrEP Conversations Among Latino Men Who Have Sex With Men.

BACKGROUND: US Latino men who have sex with men (LMSM) are a group at highest risk for HIV. One driver of HIV among LMSM is inadequate access to pre-exposure prophylaxis (PrEP) information. The social network theory of homophily suggests that sharing similar sociodemographic factors could influence PrEP conversations within networks. This study aimed to determine how the effects of homophily across sociodemographic, immigration, cultural, and PrEP-related factors are associated with PrEP-related communication. SETTING: This study was conducted in Miami-Dade County, FL. METHODS: Data collected between August 2018 and October 2019 included 10 sociocentric friendship groups of 13 LMSM (N = 130). Participants were recruited using respondent-driven sampling by a community-based organization in Miami. We used the multiple regression quadratic assignment procedure to identify the effects of homophily and relationship characteristics on PrEP-related conversations using R software. RESULTS: More frequent PrEP-related conversations were associated with dyadic friendships characterized by homophily on knowledge of PrEP effectiveness, heterophily on depressive symptom severity, home addresses proximity, friend closeness, and interaction frequency. Past PrEP-related conversation frequency also increased based on heterophily on the Latino cultural value of familism (ie, emotional support to family). Racial homophily, heterophily on severity of depressive symptoms, home addresses proximity, friendship closeness, and frequency of interactions increased likelihood to encourage a friend to use PrEP. DISCUSSION: Social and spatial closeness and homophily play a role in PrEP-related conversations. Information from social networks contextualized in geographic settings can be elucidated to contribute toward the design of novel opportunities to end HIV.
