Syndemic Psychosocial Conditions among Youth Living with HIV: a Latent Class Analysis.

Drug use, mental distress, and other psychosocial factors threaten HIV care for youth living with HIV (YLWH). We aimed to identify syndemic psychosocial patterns among YLWH and examine how such patterns shape HIV outcomes. Using baseline data from 208 YLWH enrolled in an HIV treatment adherence intervention, we performed latent class analysis on dichotomized responses to 9 psychosocial indicators (enacted HIV stigma; clinical depression and anxiety; alcohol, marijuana, and illicit drug misuse; food and housing insecurity; legal history). We used multinomial logistic regression to assess latent class-demographic associations and the automatic Bolck-Croon-Hagenaars method to assess HIV outcomes by class. Mean age of participants was 21 years; two thirds identified as cis male, 60% were non-Hispanic Black, and half identified as gay. Three classes emerged: "Polydrug-Socioeconomic Syndemic" (n = 29; 13.9%), "Distress-Socioeconomic Syndemic" (n = 35, 17.1%), and "Syndemic-free" (n = 142, 69.0%). Older, unemployed non-students were overrepresented in the "Polydrug-Socioeconomic Syndemic" class. Missed/no HIV care appointments was significantly higher in the "Polydrug-Socioeconomic Syndemic" class (81.4%) relative to the "Syndemic-free" (32.8%) and "Distress-Socioeconomic Syndemic" (31.0%) classes. HIV treatment nonadherence was significantly higher in the "Polydrug-Socioeconomic Syndemic" class (88.5%) relative to the "Syndemic-free" class (59.4%) but not the "Distress-Socioeconomic Syndemic" class (70.8%). Lack of HIV viral load suppression was non-significantly higher in the "Polydrug-Socioeconomic Syndemic" class (29.7%) relative to the "Syndemic-free" (16.2%) and "Distress-Socioeconomic Syndemic" (15.4%) classes. Polydrug-using, socioeconomically vulnerable YLWH are at risk for adverse HIV outcomes, warranting tailored programming integrated into extant systems of HIV care.

Socio-cognitive facilitators of ART-adherence among predominantly black sexual and gender minoritized persons living with HIV in Atlanta, Georgia: a latent profile analysis.

The Integrated Change Model describes several social and cognitive factors (e.g., health attitudes, social support, self-efficacy) that can affect medication adherence. Guided by this model, we sought to identify profiles of socio-cognitive facilitators of ART (antiretroviral therapy) adherence among diversely minoritized persons living with HIV enrolled in a behavioral intervention trial in Atlanta, Georgia (N = 477). To do this, we performed latent profile analysis on baseline responses to scales assessing 6 indicators of interest: HIV-care self-efficacy, social support, TasP (treatment-as-prevention) beliefs, trust in healthcare providers, perceived need for ART, and trust in ART. We regressed emergent profiles on internalized, enacted, and microaggressive HIV stigma and compared prospective 30-day ART adherence and several cross-sectional HIV outcomes across profiles. Mean age was 29 years; 83% of participants were non-Hispanic Black, 53% were gay/homosexual-identifying, and 12% were gender expansive. Three profiles emerged: "Constrained/Capable" (6%), featuring high self-efficacy but low-moderate provider trust, social support, TasP beliefs, ART trust, and ART need; "Conflicted" (13%), featuring high TasP beliefs, provider trust, and ART need but moderate self-efficacy, ART trust, and social support; and "Motivated" (81%), featuring high levels of all indicators. Greater internalized, enacted, and microaggressive stigma were positively associated with "Conflicted" relative to "Motivated" profile membership. ART-nonadherence, unsuppressed viral load, and viral load unawareness were more likely for the "Conflicted" relative to the "Motivated" profile. Personalized HIV care tailored to such profiles may improve ART adherence and related outcomes for minoritized persons living with HIV.

Emotion regulation as a potential moderator of the association between HIV stigma and nonadherence to antiretroviral therapy among youth living with HIV.

INTRODUCTION: Human immunodeficiency virus (HIV)-related stigma affects adherence to antiretroviral therapy (ART) for youth living with HIV. Emotion regulation strategies such as cognitive reappraisal (reinterpreting adversity to mitigate emotional impact) and expressive suppression (inhibiting emotion-expressive behavior activated by adversity) may moderate the HIV stigma-ART adherence relationship in this group. METHODS: Using baseline data from 208 youth living with HIV aged 15-24 years enrolled in an mHealth ART-adherence intervention, we performed modified Poisson regressions with robust variance between HIV stigma (internalized, anticipated, enacted) and ART nonadherence. We tested for multiplicative interaction via product terms between HIV stigma and emotion regulation scores, and additive interaction via relative excess risk due to interaction and attributable proportion using dichotomous HIV stigma and emotion regulation variables. RESULTS: Mean age was 21 years; ≥50% of participants were cisgender male, non-Hispanic Black, and gay-identifying; 18% reported ART nonadherence. Confounder-adjusted regressions showed positive associations between each HIV stigma variable and ART nonadherence. Internalized HIV stigma and cognitive reappraisal negatively, multiplicatively interacted (as internalized HIV stigma increased, ART nonadherence increased for those with low cognitive reappraisal). High internalized HIV stigma positively, additively interacted with low cognitive reappraisal and low expressive suppression (when high internalized HIV stigma and low levels of either emotion regulation strategy were present, ART nonadherence increased dramatically). CONCLUSION: Cognitive reappraisal and expressive suppression may protect against internalized HIV stigma's harmful association with ART nonadherence. These modifiable emotion regulation strategies may be targeted to potentially buffer the effects of internalized HIV stigma and support ART adherence for youth living with HIV.

Intersecting Sexual Behavior and Gender Identity Stigmas Among Transgender Women in the United States: Burden and Associations with Sexual Health.

In the United States, a context of multiple marginalization shapes sexual health disparities experienced by transgender women. Using data from 396 transgender women with negative or unknown HIV status, we performed exploratory factor analysis on responses to gender identity and sexual behavior stigma items and regressed sexual health outcomes on extracted factors via modified Poisson regression with robust variance estimation. Overall, 97.2% of participants endorsed ≥ 1 gender identity stigma; 67.2% endorsed ≥ 1 sexual behavior stigma; and 66.9% endorsed ≥ 1 of each. Extracted factors included gender-identity social stigma, reflecting experiences related to family, fearfulness in public, and verbal harassment (α = 0.68); gender-identity institutional stigma/violence, reflecting experiences related to healthcare, police interactions, and interpersonal violence (α = 0.73); and global sexual behavior stigma, reflecting experiences related to family, friends, and healthcare, as well as police interactions, fearfulness in public, verbal harassment, and interpersonal violence (α = 0.83). Gender-identity social stigma was significantly, positively associated with testing for HIV and testing for sexually transmitted infections. Gender-identity institutional stigma/violence and global sexual behavior stigma were both significantly, positively associated with condomless anal sex, sex work, testing for HIV, testing for sexually transmitted infections, and use of HIV pre-exposure prophylaxis. Stigma-mitigation remains critical to improve quality of life and sexual health for transgender women in the United States.

Injection Drug Use and Sexual Risk Behaviors Among People who Inject Drugs in Ukraine: A Random-Intercept Latent Transition Analysis.

HIV transmission in Ukraine is driven in part by unsafe injection drug use and sexual risk behaviors among people who inject drugs. We performed a random-intercept latent transition analysis on responses to 9 binary injection drug use and sexual behavior items from 1195 people who inject drugs with negative HIV status enrolled in a clustered randomized clinical trial of a social network intervention in Odessa, Donetsk, and Nikolayev, Ukraine. We identified 5 baseline classes: "Social injection/equipment-sharing" (11.7%), "Social injection" (25.9%), "High-risk collective preparation/splitting" (17.0%), "Collective preparation/splitting" (11.3%), and "Dealer-facilitated injection" (34.1%). After 12 months, intervention participants were more likely to transition to the "Collective preparation/splitting" class, which featured the fewest risk behaviors. Transitioning from the "Collective preparation/splitting" to the "Social injection/equipment-sharing" class was associated with HIV acquisition for control participants. Research to illuminate the stability of these patterns and how they may benefit from uniquely tailored programming to reduce unsafe behaviors is needed.

Promoting HIV care continuum outcomes among people who use drugs and alcohol: a systematic review of randomized trials evaluating behavioral HIV care interventions published from 2011 to 2023.

BACKGROUND: Substance use remains a robust predictor of HIV infection and a serious impediment to HIV care continuum progression for people living with HIV. The primary research question of this systematic review is focused on understanding the extent to which behavioral HIV care interventions have been efficacious in helping people who live with HIV and who use substances along the HIV care continuum. METHODS: Using PubMed and ProQuest databases, we performed a systematic review of randomized trials of behavioral HIV care continuum interventions among people who use substances published from 2011 to August 2023, since the beginning of the treatment-as-prevention era. RESULTS: We identified 11 studies (total participants: N = 5635), ten intentionally targeting substance-using populations. Four studies involved samples using ≥ 1 substance (e.g., alcohol, opioids, stimulants, marijuana); four involved injection drug use; one involved methamphetamine use; and one involved alcohol use. One study targeted a population with incidental substance use (i.e., alcohol, injection drug use, non-injection drug use reported in most participants). Each study defined one or more HIV care outcomes of interest. Viral suppression was an outcome targeted in 9/11 studies, followed by uptake of antiretroviral therapy (ART; 7/11), ART adherence (6/11), retention in care (5/11), and linkage to care (3/11). While most (nine) of the studies found significant effects on at least one HIV care outcome, findings were mostly mixed. Mediated (2/11) and moderated (2/11) effects were minimally examined. CONCLUSIONS: The results from this systematic review demonstrate mixed findings concerning the efficacy of previous HIV care interventions to improve HIV care continuum outcomes among people who use substances. However, heterogeneity of study components (e.g., diversity of substances used/assessed, self-report vs. objective measures, attrition) prevent broad deductions or conclusions about the amenability of specific substance-using populations to HIV care intervention. More coordinated, comprehensive, and targeted efforts are needed to promote and disentangle intervention effects on HIV care continuum outcomes among substance-using populations.

Lifetime prevalence of syphilis infection among predominantly Black sexual and gender minorities living with HIV in Atlanta, Georgia: a cross-sectional analysis.

OBJECTIVES: Syphilis infection disproportionately impacts Black sexual and gender minorities (SGM) in the United States. The extent of this impact among those living with HIV has been minimally examined. This study sought to examine lifetime syphilis prevalence and associated factors in a community sample of predominantly Black SGM living with HIV in the Southeastern US. DESIGN: Participants (N = 174) enrolled in a stigma-mitigation trial for people living with HIV in Atlanta, Georgia, completed a sub-study involving testing for Treponema pallidum antibodies, indicative of lifetime syphilis infection. We performed chi-square and Fisher's exact tests to assess sociodemographic and healthcare differences by presence/absence of lifetime syphilis infection. RESULTS: Most participants identified as non-Hispanic Black (n = 142/174; 81.6%) and cisgender male (n = 146/174; 83.9%). More than two thirds (n = 120/174) identified as gay/homosexual. We documented a 55.7% (n = 97/174) lifetime prevalence of syphilis infection and observed differences by sexual identity, with 77.3% (n = 75/97) of those screening positive reporting gay/homosexual identity relative to 58.4% (n = 45/77) of those screening negative (chi-square[1] = 7.8, p < 0.010). CONCLUSION: Findings underscore how syphilis prevention efforts have missed the most marginalized, warranting a renewed, comprehensive strategy for improving the sexual health of Black SGM. Embedding targeted, respectful community engagement, expanded testing access, and healthcare provider training into broader sexual health and psychosocial wellness efforts is needed.

Branched sexuality and sexual health among Black cisgender sexual minority men in Baltimore, Maryland: an exploratory study.

Branched sexuality - in form of combinations of sexual identity, behaviour and attraction (e.g. heterosexual identity, sex with men, attraction to women) that differ from coincident combinations (e.g. gay/homosexual/same-gender-loving identity, sex with men, attraction to men) - has been observed among Black sexual minority men and may correlate with sexual health. Using baseline survey data from Black sexual minority men (N = 323) enrolled in a sexual health intervention trial, we examined sexual identity, behaviour and attraction to determine the prevalence of branched sexuality and used modified Poisson regression with robust variance estimation to test associations with sexual health. Black sexual minority men reporting branched sexuality (n = 50, 15.5%) were marginally more likely to endorse negative condom-use attitudes compared to those reporting coincident sexuality (n = 273, 84.5%; adjusted prevalence ratio [aPR] = 1.48, 95% confidence interval [CI] = 0.94, 2.32) and significantly more likely to endorse negative condom-use attitudes compared to those reporting gay/homosexual/same-gender-loving-coincident sexuality (aPR = 1.85, 95% CI = 01.07, 3.22). Those reporting branched sexuality were significantly less likely to report past-year testing for sexually transmitted infections compared to those reporting coincident (PR = 0.52, 95% CI = 0.28, 0.94) or gay/homosexual/same-gender-loving-coincident sexuality (PR = 0.46, 95% CI = 0.25, 0.84) in bivariate analyses only. Increased understanding of Black sexual minority men's sexuality and improved sexuality data collection efforts are needed.

Effects of a social network intervention on HIV seroconversion among people who inject drugs in Ukraine: moderation by network gender composition.

BACKGROUND: Women who inject drugs in Ukraine are disproportionately burdened by HIV. To help address the needs of this population, a greater understanding of how interventions may uniquely benefit women who inject drugs is needed. METHODS: Data come from a randomized controlled trial of a social network intervention targeting people who inject drugs in Ukraine (N = 1195). Indexes, plus two of their injection network members, received HIV testing and counseling (control arm) or HIV testing and counseling plus a social network intervention (intervention arm), in which indexes were trained to influence network members' risk behaviors. We used Cox regressions with interaction terms to assess differences in time to HIV seroconversion between arms by network gender composition and gender of the index. For significant interaction terms, we calculated simple effects, generated survival functions using Kaplan-Meier methods, and compared survival curves using log-rank tests. RESULTS: At 12 months, there were 45 seroconversions among women (40.0 [28.3, 51.7] per 100 person years) and 111 among men (28.4 [23.1, 33.6] per 100 person years) in the control arm; there were 27 seroconversions among women (17.1 [10.7, 23.6] per 100 person years) and 77 among men (18.7 [14.5, 22.9] per 100 person years) in the intervention arm. Network gender composition (but not gender of the index) moderated the intervention effect on HIV incidence (p < 0.05). Specifically, the intervention appeared to be even more protective against HIV acquisition as female gender composition increased. In the intervention arm, the HIV seroconversion hazard rate was 44% lower with 1 network female; 61% lower with 2 network females; and 72% lower with 3 network females. CONCLUSIONS: A greater number of women in an injection network, coupled with the provision of risk-reduction strategies, is associated with HIV risk-mitigation, though the mechanisms through which this occurs remain unclear. Findings can support new research and practice directions that prioritize women who inject drugs and more thoughtfully support their health and wellbeing.

Metrics of Sexual Behavior Stigma Among Cisgender Men Who Have Sex With Men in 9 Cities Across the United States.

Men who have sex with men (MSM) in the United States are stigmatized for their same-sex practices, which can lead to risky sexual behavior, potentiating risk for human immunodeficiency virus (HIV) infection. Improved measurement is necessary for accurately reporting and mitigating sexual behavior stigma. We added 13 sexual behavior stigma items to local surveys administered in 2017 at 9 sites in the Centers for Disease Control and Prevention's National HIV Behavioral Surveillance system, which uses venue-based, time-sampling procedures to survey cisgender MSM in US Census Metropolitan Statistical Areas. We performed exploratory factor analytical procedures on site-specific (Baltimore, Maryland; Denver, Colorado; Detroit, Michigan; Houston, Texas; Nassau-Suffolk, New York; Portland, Oregon; Los Angeles, California; San Diego, California; and Virginia Beach-Norfolk, Virginia) and pooled responses to the survey items. A 3-factor solution-"stigma from family" (α = 0.70), "anticipated health-care stigma" (α = 0.75), and "general social stigma" (α = 0.66)-best fitted the pooled data and was the best-fitting solution across sites. Findings demonstrate that MSM across the United States experience sexual behavior stigma similarly. The results reflect the programmatic utility of enhanced stigma measurement, including tracking trends in stigma over time, making regional comparisons of stigma burden, and supporting evaluation of stigma-mitigation interventions among MSM across the United States.

Patient sexuality disclosure experience and associations with clinical sexual health outcomes among HIV-negative men who have sex with men in Mexico.

Many men who have sex with men (MSM) do not disclose their sexuality to their healthcare provider, despite potential health benefits. Data from the 2017 Encuesta de Sexo Entre Hombres online survey of 13,277 HIV-negative or unknown status MSM in Mexico were used to explore MSM patients' sexuality disclosure experience on sexual health outcomes using multivariable Poisson models with robust variance estimation to estimate adjusted prevalence ratios (aPR). Sexual health outcomes included Hepatitis B (HepB) and human papillomavirus (HPV) vaccination, and lifetime and past year HIV testing. Overall, 53.9% (n/N) disclosed their sexuality to their healthcare provider, and of those 6.4%, 62.9%, and 30.7% reported a negative, neutral, or positive disclosure experience, respectively. In comparison to no disclosure, neutral and positive disclosure experiences were associated with HepB vaccination (aPR[95% Confidence Interval (95% CI)] = 1.17[1.09, 1.25], p < 0.001; aPR[95% CI] = 1.35[1.25, 1.46], p < 0.001, respectively) and positive disclosure experiences were associated with HPV vaccination (aPR[95% CI] = 1.46[1.24, 1.71], p < 0.001). Those who disclosed their sexual behavior were more likely than those who did not disclose their sexual behavior to have received an HIV test in their lifetime (negative: aPR[95% CI] = 1.51[1.43, 1.60], p < 0.001; neutral: aPR[95% CI] = 1.61[1.56, 1.66], p < 0.001; positive: aPR[95% CI] = 1.64[1.58, 1.69], p < 0.001) and an HIV test in the past year (negative: aPR[95% CI] = 1.89[1.70, 2.10], p < 0.001; neutral: aPR[95% CI] = 2.09[1.98, 2.20], p < 0.001; positive: aPR[95% CI] = 2.24[2.12, 2.37], p < 0.001). There is a need to implement trainings for healthcare providers that focus on sexual health risk assessments and creating a space that encourages MSM patients and healthcare providers to discuss sexual health.

Metrics of sexual behavior stigma among cisgender men who have sex with men in Mexico: exploratory and confirmatory factor analyses.

Cisgender gay, bisexual, and other men who have sex with men (MSM) in Mexico experience disparities in sexual health outcomes, perhaps most notably in HIV prevalence, HIV testing and status awareness, and condom use. Sexual behavior stigma, underpinned by socio-structural factors specific to Mexico (e.g., machismo), uniquely shapes these sexual health disparities. However, few reliable, valid measures are available to document, track, and ultimately mitigate sexual behavior stigma in this context. Exploratory and confirmatory factor analyses were performed on responses to a 13-item sexual behavior stigma scale from 15,681 MSM recruited online across Mexico. Associations with extracted factors were tested to assess construct validity. Three subscales were identified in exploratory factor analysis and validated in confirmatory factor analysis: "stigma from family and friends" (α = 0.65), "anticipated healthcare stigma" (α = 0.84), and "general social stigma" (α = 0.70). External construct validity was indicated through each subscale's strong association (all p < 0.001) with perceived community intolerance of MSM and perceived community discrimination toward people living with HIV. These subscales show promise as reliable, valid measures for assessing sexual behavior stigma among MSM in Mexico, and as tools for documenting and tracking sexual behavior stigma trends, comparing regional burdens of sexual behavior stigma, and tracking the progress of stigma-mitigation interventions among MSM in Mexico. Future research is needed to understand the extent to which each subscale is differentially associated with sexual (and other) health outcomes, which can inform the development and implementation of uniquely tailored stigma-mitigation, HIV-prevention, HIV-care, and other needed interventions for MSM in Mexico.

Sex-Positivity, Medical Mistrust, and PrEP Conspiracy Beliefs Among HIV-Negative Cisgender Black Sexual Minority Men in Atlanta, Georgia.

Because the public health response to the disproportionate HIV burden faced by Black sexual minority men (BSMMM) has focused on sexual risk reduction and disease prevention, other vital components of sexual health (e.g., intimacy, pleasure, benefits of sex) have been often overlooked. Sex-positive describes a more open, holistic approach toward sex and sexuality that prioritizes these other components, though such an approach is rarely applied to BSMM's sexual health. For sex-positive BSMM, risk/preventive discourse may foster or exacerbate medical mistrust as a reaction to the dissonance between how these men view sexual health and how the medical establishment views it, which may discourage sexual healthcare-seeking. We assessed sex-positivity and its association with medical mistrust and PrEP conspiracy beliefs among 206 HIV-negative cisgender BSMM in Atlanta, Georgia. We performed exploratory factor analytic procedures on responses to a sex-positivity scale, followed by multivariable linear regressions to determine sex-positivity's associations with medical mistrust and PrEP conspiracy beliefs. We extracted two sex-positivity factors: sexual freedom (α = 0.90), reflecting openness toward casual sex and rejection of sexual mores, and essence of sex (α = 0.77), reflecting the intimate, relational, and pleasurable qualities of sex. Sexual freedom was independently associated with perceived provider deception (ß = 0.19, CI = 0.04, 0.34). Essence of sex was independently associated with PrEP conspiracy beliefs (ß = 0.16, CI = 0.02, 0.31) and marginally associated with perceived provider deception (ß = 0.14, CI = - 0.00, 0.29). Healthcare providers and public health practitioners may cultivate greater trust with BSMM by incorporating a sex-positive approach into patient/participant interactions, clinical decision-making, and interventions. Improving access to sexual pleasure acknowledges BSMM's right to optimal, holistic sexual health.

Associations between HIV testing and multilevel stigmas among gay men and other men who have sex with men in nine urban centers across the United States.

BACKGROUND: Complex manifestation of stigma across personal, community, and structural levels and their effect on HIV outcomes are less understood than effects in isolation. Yet, multilevel approaches that jointly assesses HIV criminalization and personal sexual behavior stigma in relation to HIV testing have not been widely employed or have only focused on specific subpopulations. The current study assesses the association of three types of MSM-related sexual behavior-related stigma (family, healthcare, general social stigma) measured at both individual and site levels and the presence/absence of laws criminalizing HIV transmission with HIV testing behaviors to inform HIV surveillance and prevention efforts among HIV-negative MSM in a holistic and integrated way. METHODS: We included nine National HIV Behavioral Surveillance (NHBS) 2017 sites: Baltimore, MD; Denver, CO; Detroit, MI; Houston, TX; Long Island/Nassau-Suffolk, NY; Los Angeles, CA; Portland, OR; San Diego, CA; and Virginia Beach and Norfolk, VA. Multivariable generalized hierarchical linear modeling was used to examine how sexual behavior stigmas (stigma from family, anticipated healthcare stigma, general social stigma) measured at the individual and site levels and state HIV criminalization legislation (no, HIV-specific, or sentence-enhancement laws) were associated with past-year HIV testing behaviors across sites (n = 3,278). RESULTS: The majority of MSM across sites were tested for HIV in the past two years (n = 2,909, 95.4%) with the average number of times tested ranging from 1.79 (SD = 3.11) in Portland, OR to 4.95 (SD = 4.35) in Los Angeles, CA. In unadjusted models, there was a significant positive relationship between stigma from family and being tested for HIV in the past two years. Site-level HIV-specific criminalization laws were associated with an approximate 5% reduction in the prevalence of receiving any HIV test in the past two years after individual level stigma and sociodemographic covariate adjustments (PR = 0.94, 95% CI, 0.90-0.99). CONCLUSIONS: Structural barriers faced by MSM persist and ending the HIV epidemic in the US requires a supportive legal environment to ensure effective engagement in HIV services among MSM. Home-based solutions, such as self-testing, used to deliver HIV testing may be particularly important in punitive settings while legal change is advocated for on the community and state levels.

Disclosure of same-sex practices and experiences of healthcare stigma among cisgender men who have sex with men in five sub-Saharan African countries.

BACKGROUND: For men who have sex with men (MSM) across sub-Saharan Africa (SSA), disclosure of same-sex practices to family and healthcare workers (HCWs) can facilitate access to HIV prevention services and support, but can also lead to experiences of stigma. METHODS: We performed mixed-effects regressions on pooled data from MSM in Cameroon, Senegal, Côte d'Ivoire, Lesotho, and eSwatini to assess associations between disclosure and sexual behavior stigma in healthcare contexts; we used logistic regressions to analyze country-specific data. RESULTS: Compared to participants who had not disclosed to either family or HCWs, those who had disclosed only to family were more likely to have been gossiped about by HCWs (aOR = 1.70, CI = 1.18, 2.45); the association between having disclosed to family and having felt mistreated in a health center approached, but did not achieve, statistical significance (aOR = 1.56, CI = 0.94, 2.59). Those who had disclosed only to HCWs were more likely to have feared to seek health services (aOR = 1.60, CI = 1.14, 2.25), avoided health services (aOR = 1.74, CI = 1.22, 2.50), and felt mistreated in a health center (aOR = 2.62, CI = 1.43, 4.81). Those who had disclosed to both were more likely to have feared to seek health services (aOR = 1.71, CI = 1.16, 2.52), avoided health services (aOR = 1.59, CI = 1.04, 2.42), been gossiped about by HCWs (aOR = 3.78, CI = 2.38, 5.99), and felt mistreated in a health center (aOR = 3.39, CI = 1.86, 6.20). Country-specific analyses suggested that data from Cameroon drove several of these associations. CONCLUSIONS: Research to determine the factors driving disclosure's differential effect on healthcare stigma across contexts is needed. Ultimately, supportive environments enabling safe disclosure is critical to understanding HIV-acquisition risks and informing differentiated HIV-prevention, treatment, and testing services for MSM across SSA.

SEX COMPOSITION OF TWINS AND ASSOCIATIONS WITH MORBIDITY, MORTALITY AND MATERNAL TREATMENT-SEEKING OUTCOMES IN RESOURCE-POOR SETTINGS.

Societal gender inequality and a preference for male children has been shown to be detrimental to girls' health. This is despite females' innate biological advantage early in life. The negative effects of gender inequity on female health are most pronounced in resource-poor countries, where cultural norms supporting a preference for male children are strongest. However, most of what is known about gender inequality and child health comes from studies of singleton births. There is little evidence for how, or if, the disadvantages associated with gender bias and son preference extend to multiple births, a population inherently at risk for a number of health challenges. This analysis examines whether gender bias in health outcomes exists for twins. Data on live twin births from 38 Demographic and Health Surveys were compiled (n=11,528 individuals) and twins were categorized as girl/girl, girl/boy, boy/girl or girl/girl. Gender inequality was measured via the Gender Inequality Index. Multilevel logistic regression models examined associations between twin sex composition, gender inequality and eight outcomes of infant and child morbidity, mortality and mother's treatment-seeking behaviours. Twin pairs containing girls had significantly lower odds of first-year mortality. Higher country-level gender inequality was associated with higher odds of reporting diarrhoea and fever/cough, as well as an increased odds of post-neonatal mortality. Results suggest that the biological advantage for females may be stronger than son preference and gender inequality in the first year of life. Understanding these relationships has the potential to inform efforts to curb the influence of gender preference on the health of female children in resource-poor settings.

Measuring sexual behavior stigma among cisgender men who have sex with men: an assessment of cross-country measurement invariance.

Objectives: Globally, cisgender men who have sex with men experience sexual stigma, but limited investigation of cross-population scale performance hinder comparisons. As measurement invariance is a necessary but seldom-established criterion of valid cross-cultural comparisons, we assessed invariance in scales of stigma related to sexual behavior across 9 countries. Methods: This secondary analysis used data collected from adult (mean age=29.6, standard deviation=12.5) cisgender men who have sex with men (n=8,669) in studies from 6 West African, 2 Southern African, and 1 North American country from 2012-2016. A common item set assessed 2 sexual behavior stigma domains. A sequential process was used to test the factor structure and measurement invariance, which included multigroup confirmatory factor analyses (CFA). Individual countries, items, living with HIV, and disclosure were explored as possible sources of noninvariance. Results: Goodness-of-fit statistics indicated adequate fit of the same 2-factor model in 7 of the 9 countries. The chi2 difference test comparing a constrained and unconstrained 7-country model in which loadings and thresholds were freely estimated was significant (p<0.001), indicating metric and scalar noninvariance, but removing the US provided evidence of invariance and freeing certain items led to a finding of partial invariance. Sexuality disclosure exhibited a direct relationship with select stigma items in several countries. Conclusions: Our findings point to the utility of the two stigma scale dimensions in making cross-country comparisons, but also to the necessity of assessing invariance with explicit attention to several factors including differential disclosure of sexuality across contexts to ensure valid comparisons.

Targeted Violence as a Risk Factor for Posttraumatic Stress Disorder Among Cisgender Gay, Bisexual, and Other Men Who have Sex with Men in the United States.

Gay, bisexual, and other men who have sex with men (GBMSM) in the United States (US) are disproportionately exposed to interpersonal violence, which carries a high conditional risk for developing posttraumatic stress disorder (PTSD) and which is often motivated by sexual prejudice. We determined PTSD prevalence by violence attribution (motivated by sexual prejudice or not) and measured PTSD-attribution associations. Using a 2020 nationwide cross-sectional survey of 2,886 GBMSM who reported ever experiencing interpersonal violence, we performed multivariable modified Poisson regressions with robust variance estimators to examine differences in prevalence of current PTSD by how participants attributed the violence (occurring due to one's same-sex practices, not occurring due to one's same-sex practices, or being unsure if it occurred due to one's same-sex practices). Model results are reported as adjusted prevalence ratios (aPR) with 95% confidence intervals (CI). Median age was 27 years; 78.8% of participants identified as gay, and 62.2% were non-Hispanic White. Violence was attributed to same-sex practices by 45.8% of participants; 46.3% did not make this attribution, and 7.0% were unsure (0.9% preferred not to answer). Overall, 23.0% screened positive for PTSD, and PTSD prevalence was greater for those who attributed violence to same-sex practices (25.9% [342/1,321]; aPR = 1.55, 95% CI [1.34, 1.79]) and those who were unsure (33.5% [68/203]; aPR = 1.80, 95% CI [1.44, 2.25]) compared to those who did not make the attribution (18.1% [242/1,335]). Age modified this association, with participants 15 to 19 years old who made the attribution being significantly more likely to have PTSD relative to 20+ participants who also made the attribution. In addition to violence-prevention and stigma-mitigation efforts, interventions targeting attribution styles may be useful for violence-exposed GBMSM, especially teenagers.

Factors Associated with Disclosure of Sexual Orientation Among Black Sexual Minority Men.

Purpose: This study evaluated the characteristics associated with sexual orientation disclosure among HIV-negative Black sexual minority men (BSMM) in the greater Atlanta, Georgia area. Survey data were collected from 475 HIV-negative BSMM from 2017 to 2019 as part of a larger behavioral intervention study focused on stigma, prejudice, and HIV-testing uptake. Methods: Participants reported their levels of sexual orientation disclosure globally, to their community, and to their family. Data were analyzed using one-way analysis of variance and multinomial logistic regression to determine whether demographic, minority stress, substance use, and mental health were associated with sexual orientation disclosure globally, to community members, and to family members. Results: Findings revealed that participants with older age, bisexual identity, and higher levels of internalized homophobia had higher odds of global, community, and family sexual orientation nondisclosure. Furthermore, participants with higher levels of resilience had lower odds of partial sexual orientation disclosure compared with their fully disclosed counterparts. Conclusions: These findings reveal variations associated with sexual orientation disclosure across varying contexts among HIV-negative BSMM, particularly among family member disclosure.
