HIV testing and HIV knowledge among men who have sex with men in Natal, Northeast Brazil

Barriers and facilitators for HIV rapid testing among transgender women and gay and other men who have sex with men in Brazil: A scoping review

Transgender women (TGW) and men who have sex with other men (MSM) often encounter disparities in accessing HIV testing, leading to delayed diagnoses and worse prognoses. We analysed barriers and facilitators for accessing HIV rapid testing by TGW and MSM in Brazil, 2004-2023. Citations were included whether the study population consisted of individuals aged ≥18y old, and studies addressed HIV testing and have been conducted in Brazil. The study protocol was based on Joanna Briggs' recommendations for scoping reviews. We included 11 studies on TGW and 17 on MSM. The belief that one is not at risk of contracting HIV infection, fear expressed in different ways (e.g. lack of confidentiality) and younger age were the main barriers. Feeling at risk for HIV infection, curiosity, and favourable characteristics of the setting where the testing takes place were cited as the main facilitators. Barriers and facilitators specifically for HIV self-testing included, respectively, concerns about conducting the test alone vs. autonomy/flexibility. Brazil is unlikely to achieve the UN' 95-95-95 goal without minimising testing disparities. Combating prejudice against TGW and MSM in testing settings, along with educational campaigns and transparent protocols to ensure confidentiality, can help increase HIV testing among these populations.

Knowledge of HIV and/or AIDS and HIV testing services among young men in South Africa

BACKGROUND

The youth is at a heightened risk of immunodeficiency virus and/or acquired immunodeficiency syndrome (HIV and/or AIDS) infection because of risk-taking behaviour. There remains a gap in understanding young men's knowledge of HIV and/or AIDS and HIV testing services (HTS) in hard-to-reach communities in South Africa.

AIM

This article aimed to explore young men's knowledge of HIV and/or AIDS, including HTS in Ladysmith, KwaZulu-Natal (KZN).

SETTING

Rural and peri-urban areas around the town of Ladysmith.

METHODS

Employing a qualitative descriptive research design, 17 young men aged between 18 and 30 years were purposively and conveniently sampled and interviewed using WhatsApp and landline audio calls to collect their data, which was thematically analysed.

RESULTS

Young men had good knowledge of HIV and/or AIDS but lacked knowledge about HTS and HIV self-testing (HIVST). They obtained their information about HIV and/or AIDS and HTS from various sources and were aware of where to access HTS. They were generally unaware and supportive of HIVST.

CONCLUSION

Male-targeted HIV and/or AIDS knowledge and testing interventions are needed to encourage and support young men to test for HIV. Human immunodeficiency virus self-testing should be explored as an alternative to clinic-based service to encourage young men to know their status, specifically those with limited access to or are reluctant to attend clinics. Strengthening HIV and/or AIDS education could facilitate better decision-making towards HIV testing among young men.Contribution: This study contributes to an understanding of young adult men's knowledge of HIV and/or AIDS and HTS in underserved settings in South Africa.

Factors associated to HIV prevalence among adolescent men who have sex with men in Salvador, Bahia State, Brazil: baseline data from the PrEP1519 cohort

Adolescent men who have sex with men (AMSM) are at a heightened vulnerability for human immunodeficiency virus (HIV). This study aimed to estimate the prevalence of HIV and associated individual, social, and programmatic factors among AMSM in Salvador, Bahia State, Brazil. This is a cross-sectional study which analyzed baseline data from the PrEP1519 cohort in Salvador. Descriptive, bivariate, and multivariate analyses were conducted using the dimensions of vulnerability to HIV as hierarchical levels of analysis. Logistic regression models were used to estimate the odds ratios (OR) of the association between predictor variables and HIV infection. The prevalence of HIV infection among the 288 AMSM recruited to the project was 5.9% (95%CI: 3.7-9.3). Adjusted analysis showed a statistically significant association between self-identifying as a sex worker (OR = 3.74, 95%CI: 1.03-13.60) and HIV infection. Other associations with borderline statistical significance were the use of application programs to find sexual partners (OR = 3.30, 95%CI: 0.98-11.04), low schooling level (OR = 3.59, 95%CI: 0.96-13.41), failing to be hired or being dismissed from a job because of sexual orientation (OR = 2.88, 95%CI: 0.89-9.28), and not using health services as a usual source of care (OR = 3.14, 95%CI: 0.97-10.17). We found a high HIV prevalence among AMSM in Salvador. Furthermore, our study found that individual, social, and programmatic factors were associated with HIV infection among these AMSM. We recommend intensifying HIV combined-prevention activities for AMSM.

Development and Evaluation of Short-Form Measures of the HIV/AIDS Knowledge Assessment Tool Among Sexual and Gender Minorities in Brazil: Cross-sectional Study

Background

In theoretical models of health behavior, knowledge about disease transmission and self-protective behaviors are conceptualized as important drivers of behavior change. Several studies conducted in Brazil point to an unfortunate convergence of sexual and gender minority (SGM) populations with low levels of HIV knowledge and younger age, lower education, engagement in higher-risk sexual behavior, and never having tested for HIV. Measures to assess level of HIV knowledge have been previously published, including the 12-item HIV/AIDS Knowledge Assessment (HIV-KA) tool. However, measure length can be a barrier to assessment.

Objective

We started from the 12-item HIV-KA tool and developed candidate short forms using statistical procedures, evaluated their psychometric properties, and tested the equivalency of their associations with other measures of HIV knowledge compared to the 12-item version.

Methods

A convenience sample of SGM was recruited during September 2020 to complete an online survey through advertisements on two social networking apps (Grindr and Hornet). The survey instrument included items on sociodemographic information, prior HIV testing and HIV test results, preexposure prophylaxis (PrEP) and antiretroviral treatment use, sexual behavior, and 3 HIV knowledge measures: the HIV-KA, World Health Organization Knowledge About HIV Transmission Prevention Indicator, and the Brief HIV Knowledge Questionnaire. We used exploratory factor analysis and confirmatory factor analysis (CFA) to assess the factor structure of the of the HIV-KA. We used optimal test assembly (OTA) methods to develop candidate short forms of the HIV-KA and evaluated them based on prespecified reliability, concurrent validity, and statistically equivalent convergent validity criteria.

Results

Among 2552 SGM individuals from Brazil, mean age was 35.1 years, 98.2% (2507/2552) cisgender men and 1.8% (45/2552) transgender/nonbinary, 56.5% (1441/2552) White, and 31.0% (792/2552) self-reported HIV positive. CFA indicated a 1-factor structure for the 12-item HIV-KA. Concurrent validity correlations were high for all short forms with 6 items, but only versions with 9 items were as reliable as the full-length form and demonstrated equivalency for convergent validity correlations. Suggesting post hoc convergent validity, HIV knowledge scores using the 9- and 10-item short forms were higher for participants who perceived the Undetectable Equals Untransmittable (U=U) slogan as completely accurate versus not accurate. Suggesting post hoc concurrent validity, participants of younger age, of Black, Pardo or indigenous race, and reporting lower education and lower income scored lower on HIV knowledge. Participants who never tested for HIV scored lower than those who tested negative or positive, while those currently using PrEP scored higher than those reporting past or never use.

Conclusions

OTA methods were used to shorten the 12-item HIV-KA to 9-item and 10-item versions while maintaining comparable reliability and validity among a large sample of Brazilian SGM. However, these short forms did not shorten sufficiently to justify deviation from the full measure.

Factors associated with past HIV testing among men who have sex with men attending university in China: a cross-sectional study

Background HIV prevalence has been rapidly increasing among men who have sex with men (MSM) attending university in China, but HIV testing rates remain suboptimal. The factors associated with past HIV testing in this population in Beijing, China, were investigated.

METHODS

This study used data from the baseline survey of an HIV intervention clinical trial among MSM who did not have a history of a positive HIV diagnosis. This analysis focused on the HIV testing experience in a subgroup of university student MSM participants. Log-binomial models were used to evaluate factors associated with past HIV testing.

RESULTS

Of 375 university student MSM, the median age was 22 years; 89.3% were Han ethnic. Approximately half (50.4%, n = 189) had ever taken an HIV test before the survey. In a multivariable log-binomial model, older age (adjusted prevalence ratio (APR), 1.04; 95% confidence interval (CI), 1.02-1.06), had first sexual intercourse at age <18 years (APR, 1.35; 95% CI, 1.08-1.45) and knew someone living with HIV (APR, 1.33; 95% CI, 1.07-1.61) were associated with a higher likelihood of past testing. Self-reported barriers to taking a test included perceived low HIV risk, fear of a positive diagnosis, did not know where to get tested and fear of discrimination. Facilitators included anonymity in taking a test, confidentiality of testing results and availability of home-based and rapid testing.

CONCLUSIONS

The HIV testing rate among university student MSM was low. Interventions should be implemented to address structural, institutional and individual barriers to HIV testing in this vulnerable population.

Testagem para o HIV e profilaxia pós-exposição entre homens que fazem/ não fazem sexo com homens

Resumo Objetivos identificar a realização da testagem para o HIV e o conhecimento sobre profilaxia pós-exposição (PEP) entre homens; e comparar os dados entre homens que fazem (ou não) sexo com homens. Método estudo transversal realizado com 271 homens participantes do carnaval no Rio de Janeiro, selecionados através da amostragem por conveniência. Os dados foram coletados no sambódromo, com auxílio de um questionário em fevereiro de 2017. A análise foi realizada por meio do software SPSS. Resultados houve disparidades na realização de testagem para o HIV e conhecimentos sobre PEP entre homens que fazem (ou não) sexo com homens. Homens que fazem sexo com homens possuem comportamentos e conhecimento melhores de enfrentamento ao HIV. Conclusão e implicações para a prática as políticas de enfrentamento ao HIV têm conseguido alcançar uma das populações-chave da epidemia, os homens que fazem sexo com homens, contudo homens que não fazem sexo com homens continuam vulneráveis.

Acceptability of HIV self-testing is low among men who have sex with men who have not tested for HIV: a study with respondent-driven sampling in Brazil

BACKGROUND

Brazil has many people living with HIV (PLWH) who are unaware of their serostatus. The public health system has recently added HIV self-testing (HIVST) for key populations such as men who have sex with men (MSM). This study estimates HIVST acceptability among Brazilian MSM and explores factors associated with acceptability among MSM who have never tested for HIV or who had a previous negative result.

METHODS

Respondent-driven sampling (RDS) was used to recruit 4176 MSM in 12 Brazilian cities in 2016 to this biological and behavioral surveillance study. We excluded from this analysis all MSM who were aware of their positive HIV serostatus. Descriptive, bivariate and multivariate analyses were conducted. Overall proportions were weighted with Gile's estimator in RDS Analyst software and 95% confidence intervals were calculated. The analyses of HIVST acceptability were stratified by prior HIV testing (never or one or more times).

RESULTS

For this analysis, 3605 MSM were included. The acceptability of HIVST was 49.1%, lower among those who had never tested for HIV (42.7%) compared to those who had a previous HIV negative test (50.1%). In the subgroup of MSM who had never tested for HIV, those who reported discrimination or who had a medical appointment in the last 12 months reported higher HIVST acceptability. Among MSM who had a previous negative HIV test, only those reporting condomless receptive anal sex reported higher HIVST acceptability. In addition, we observed that high levels of knowledge of HIV/AIDS, taking part in lesbian, gay, bisexual, and transgender nongovernmental organizations (LGBT-NGO), or complete secondary or incomplete higher undergraduate education reported higher acceptability.

CONCLUSIONS

The acceptability of HIVST was low among MSM, especially among those who never tested for HIV. Given access to HIVST in Brazil, we point to the need for programs that enhance promotion of testing addressed to MSM.
