Factors Associated with Having both Male and Female Recent Sexual Partnerships Among Men Who Have Sex with Men in Harare and Bulawayo, Zimbabwe.

To better understand male and female sexual partnerships among men who have sex with men (MSM), we used data from a 2019 biobehavioral survey among MSM in Harare and Bulawayo, Zimbabwe to conduct bivariate analyses and multivariable logistic regression to determine whether sociodemographic characteristics and HIV-related factors were associated with having both male and female sexual partnerships within the last 6 months. Of included MSM (N = 1143), 31% reported both male and female partnerships in the last 6 months. Being married/cohabiting (adjusted odds ratio (aOR) = 8.58, 95% confidence interval (CI) = 4.92-14.95) or separated/divorced/widowed (aOR = 1.96, 95% CI = 1.24-3.08) vs. being single, and hazardous alcohol consumption (aOR = 1.58, 95% CI 1.19-2.09) were associated with higher odds of having both male and female recent partnerships. Being aged 35 + vs. 18-24 (aOR = 0.50, 95% CI = 0.31-0.81), condomless receptive anal intercourse at last sex with the main male partner (aOR = 0.43, 95% CI = 0.26-0.74), and positive HIV status (aOR = 0.46, 95% CI = 0.31-0.67) were associated with lower odds of recent male and female partnerships. MSM in Harare who reported harassment/abuse (aOR = 3.16, 95% CI = 1.72-5.79) had higher odds of both male and female partnerships than MSM in Bulawayo reporting harassment/abuse. The prevalence of both male and female recent partnerships (31%) was lower among MSM in this survey than in other biobehavioral surveys of MSM in sub-Saharan Africa. Findings suggest that MSM with recent male and female partnerships compared to MSM with only male recent partners have lower odds of positive HIV status and participate in behaviors that lower HIV risk; however, the direction of these relationships cannot be determined due to the cross-sectional nature of the data. The findings also suggest a possible connection between experiences of stigma of MSM behavior and not having both male and female partnerships that warrants further exploration. Accessible, stigma-free HIV testing and education programming that considers the potential overlap between the MSM and general populations via both male and female partnerships and the associated behaviors could be a key component of HIV elimination in Zimbabwe.

High Burden of Active Syphilis and Human Immunodeficiency Virus/Syphilis Coinfection Among Men Who Have Sex With Men, Transwomen, and Genderqueer Individuals in Zimbabwe.

BACKGROUND: Syphilis increases human immunodeficiency virus (HIV) acquisition risk and impacts the immunologic and virologic response among people living with HIV (PLHIV). We assessed the prevalence of active or current syphilis and HIV/syphilis and their correlates among men who have sex with men (MSM), transwomen, and genderqueer (TGW/GQ) individuals in Zimbabwe. METHODS: Among a respondent-driven sample of MSM and TGW/GQ who were tested for HIV and syphilis in Harare and Bulawayo, Zimbabwe in 2019 (n = 1511), multiple logistic regression was used to assess correlates of active syphilis. Unadjusted logistic regression was used among PLHIV (n = 340) due to small sample size. All analyses were unweighted as data did not reach convergence for HIV. RESULTS: Prevalence of active syphilis overall and among PLHIV was 5.5% and 10.1%, respectively, in Harare, and 5.6% and 11.0%, respectively, in Bulawayo. Participants were more likely to have active syphilis if they were PLHIV (adjusted odds ratio [aOR], 2.2; 95% confidence interval [CI], 1.4-3.6), aged 25-34 years (aOR, 2.2 years; 95% CI, 1.3-3.8 years; reference, 18-24 years), or self-report sexually transmitted infection symptoms (aOR, 1.8; 95% CI, 1.1-3.0). Compared with Bulawayo TGW/GQ, MSM in Harare (aOR, 0.2; 95% CI, 0.1-0.5) and Bulawayo (aOR, 0.2; 95% CI, 0.1-0.4), and TGW/GQ in Harare (aOR, 0.2; 95% CI, 0.1-0.6) were less likely to have active syphilis. Among PLHIV, coinfection was 13.0% among TGW/GQ and 9.7% among MSM. Odds of coinfection were higher for those aged 25 to 34 years (OR, 3.7 years; 95% CI, 1.2-11.1 years) and lower among Harare MSM (OR, 0.2; 95% CI, 0.1-0.7), Bulawayo MSM (OR, 0.1; 95% CI, 0.0-0.4), and Harare TGW/GQ (OR, 0.1; 95% CI, 0.0-0.4) compared with Bulawayo TGW/GQ. CONCLUSIONS: Findings highlight a high burden of syphilis among MSM and TGW/GQ and underscore the importance of HIV/syphilis detection and improved service delivery for these groups.

Stigma, Social Cohesion, and HIV Risk Among Sexual and Gender Minorities in Two Cities in Zimbabwe.

Though stigma is a recognized contributor to the disproportionate HIV burden among sexual and gender minorities (SGM) in sub-Saharan Africa, data describing this association among Zimbabwean SGM are limited. We examined relationships between SGM stigma and HIV and the potential for social cohesion to moderate the association among Zimbabwean men who have sex with men, transgender women, and genderqueer individuals. Consenting participants (n = 1511) recruited through respondent-driven sampling for a biobehavioral survey in Harare and Bulawayo completed structured interviews and received HIV testing. Reported SGM stigma was common (68.9% in Harare and 65.3% in Bulawayo) and associated with HIV infection in Harare (adjusted prevalence ratio [aPR] = 1.82, 95% confidence interval [CI] = 1.27-2.62) and Bulawayo (aPR = 1.51, 95% CI = 1.15-2.00) in relative risk regression. Social cohesion did not moderate these relationships. Findings demonstrate stigma's association with HIV vulnerability among Zimbabwean SGM, highlighting the need for stigma-mitigation to reduce HIV transmission in this population.

Social and structural drivers of HIV vulnerability among a respondent-driven sample of feminine and non-feminine presenting transgender women who have sex with men in Zimbabwe.

INTRODUCTION: We sought to characterize social and structural drivers of HIV vulnerability for transgender women (TGW) in Zimbabwe, where TGW are not legally recognized, and explore differences in vulnerability by feminine presentation. METHODS: A secondary analysis was conducted with a sub-sample of participants recruited from a 2019 respondent-driven sampling survey that comprised men who have sex with men, TGW and genderqueer individuals assigned male sex at birth, from two cities in Zimbabwe. Survey questionnaires captured information related to socio-demographics, sexual and substance use behaviours, and social and structural barriers to HIV services. Secondary analyses were restricted to participants who identified as female, transfemale or transwomen (236/1538) and were unweighted. Descriptive statistics were used to calculate sample estimates and chi-square and Fisher's exact tests were used to assess differences in vulnerability by feminine presentation. RESULTS: Among 236 TGW, almost half (45.3%) presented as feminine in the 6 months preceding the survey and 8.5% had ever used hormones to affirm their gender identities. Median age among TGW was 23 years (interquartile range: 20-26). Feminine presenting TGW in our sample had higher prevalence of arrest (15.9% vs. 3.9%), rejection by family/friends (38.3% vs. 14.0%), employment termination (11.2% vs. 3.9%), employment refusal (14.0% vs. 3.9%), denial of healthcare (16.8% vs. 2.3%), physical, sexual or verbal harassment or abuse (59.8% vs. 34.1%), alcohol dependence (32.7% vs. 12.4%), recent transactional sex with a male or TGW partner (30.8% vs. 13.3%) and recent non-injection drug use (38.3% vs. 20.2%) than non-feminine presenting TGW (all p-value <0.05). CONCLUSIONS: Findings suggest that TGW, particularly feminine presenting TGW, experience social and structural inequities which may contribute to HIV vulnerability. Interventions aimed at addressing inequities, including trans competency training for providers and gender-affirming, psychosocial and legal support services for TGW, might mitigate risk.

Hepatitis B virus infection (HBV) and HIV-HBV coinfection among men who have sex with men, transgender women, and genderqueer individuals in Harare and Bulawayo Zimbabwe, 2019.

Objectives: To measure HIV and Hepatitis B virus (HBV) prevalence and associated risk behaviors among men who have sex with men (MSM) and transgender women/genderqueer individuals (TGW/GQ) in Zimbabwe. Methods: We conducted a biobehavioral survey using respondent-driven sampling (RDS) among adult MSM and TGW/GQ in Harare and Bulawayo, Zimbabwe in 2019. Participants completed a questionnaire and underwent testing for HIV and HBV. Results: Overall, 1,510 (Harare: 694, Bulawayo 816) participants were enrolled and consented to testing; 3.8 % (58) tested positive for HBV, 22.5 % (339) tested positive for HIV, and 2.2 % (33) tested positive for both HIV and HBV. HBV prevalence was higher among participants with HIV compared to HIV-negative participants (9.7 % vs. 2.1 %, p < 0.0001). Overall, HBV prevalence was not statistically different between MSM and TGW/GQ (3.7 % vs 4.5 %, p = 0.49) nor between Harare and Bulawayo (3.3 % vs 4.3 %, p = 0.33). Conclusions: Our survey demonstrates the prevalence of HBV among MSM and TGW/GQ is lower than other estimates of HBV among MSM in Africa but remains high among our survey population living with HIV highlighting the need to expand HBV testing and treatment services, especially among people with HIV in Zimbabwe.

Characterizing acceptable and appropriate implementation strategies of a biobehavioral survey among men who have sex with men and others assigned male who have sex with men in Zimbabwe.

Key populations including men who have sex with men (MSM), female sex workers, people who inject drugs, transgender persons, and prisoners account for nearly 50% of new HIV infections globally. To inform the HIV response and monitor trends in HIV prevalence and incidence among key populations, countries have increased efforts to implement biobehavioral surveys (BBS) with these groups as part of routine surveillance. Yet the marginalized nature of populations participating in a BBS requires contextually acceptable and appropriate strategies for effective implementation. We conducted a formative assessment to inform the first BBS conducted with MSM and others assigned male who have sex with men (OAMSM) in Zimbabwe, where same-sex sexual behaviors are illegal and highly stigmatized and describe applications of our findings. Qualitative data were collected through four focus groups with 32 MSM/OAMSM and 25 in-depth interviews (15 MSM/OAMSM, 10 service providers/gatekeepers) from December 2018 to January 2019. Rapid assessment techniques were employed including rapid identification of themes from audio recordings and review of detailed field notes and memos to identify key themes. Findings from this assessment included contextually relevant considerations including behaviors and terminology to avoid when working with MSM/OAMSM in Zimbabwe, appropriate compensation amounts for survey participation, proposed data collection sites, and differences in sexual openness, marital status, and networks among younger and older MSM/OAMSM. Participants also reported strong network ties suggesting respondent-driven sampling-a peer chain referral approach-to be an appropriate recruitment method in this context. Taken together, these findings highlighted key considerations and strategies for implementation to ensure the subsequent BBS in Zimbabwe was both acceptable and appropriate. These results and applications of these results are important for informing surveillance efforts and broader HIV-related engagement efforts among MSM/OAMSM in Zimbabwe as well as in other contextually similar countries in Southern Africa.

HIV care cascade and associated factors among men who have sex with men, transgender women, and genderqueer individuals in Zimbabwe: findings from a biobehavioural survey using respondent-driven sampling.

BACKGROUND: Globally, men who have sex with men (MSM), transgender women, and genderqueer individuals are at greater risk for HIV than the general population although little data are available from these groups in Zimbabwe, a country with a national adult HIV prevalence of 12·9%. We aimed to examine progress towards the UNAIDS 90-90-90 treatment targets and factors associated with meeting the targets among a sample of MSM, transgender women, and genderqueer individuals in Zimbabwe. METHODS: In this cross-sectional survey in 2019, we used respondent-driven sampling to identify MSM, transgender women, and genderqueer individuals aged at least 18 years to participate in a biobehavioural survey in Harare and Bulawayo, Zimbabwe. Participants were eligible to participate if they were assigned male at birth; had engaged in anal or oral sex with a man in the past 12 months; resided in Harare or Bulawayo for at least 1 month; spoke English, Shona, or Ndebele; provided written informed consent; and were in possession of a valid recruitment coupon if applicable. Enrolled participants completed a questionnaire and underwent HIV testing, and off-site viral load testing was done on all HIV-positive samples. Unweighted bivariate analyses and multivariable logistic regression models were used to evaluate the association of sociodemographic, behavioural, and other factors with HIV-positive status awareness among MSM, transgender women, and genderqueer individuals, and with viral load suppression among MSM. Analyses were done firstly using self-reported information and then by classifying those with a viral load of less than 200 copies per mL as being aware of their status and on treatment (viral load recategorisation). FINDINGS: Among MSM, 248 (21%; 95% CI 19-24) of 1176 tested positive for HIV. Of those who tested positive, based on self-report, 119 (48%; 95% CI 42-54) reported knowing their HIV status, of whom 112 (94%; 88-98) reported using antiretroviral therapy (ART), of whom 89 (79%; 71-87) had viral load suppression. Based on viral load recategorisation, 180 (73%; 67-78) of 248 MSM testing HIV positive reported knowing their HIV status, of whom 174 (97%; 93-99) reported using ART, of whom 151 (87%; 81-91) had viral load suppression. 92 (28%; 23-33) of 335 transgender women and genderqueer individuals tested positive for HIV. Based on self-reports from these individuals 34 (37%; 27-48) of 92 participants reported knowing their HIV status, of whom 31 (91%; 76-98) reported using ART, of whom 27 (87%; 70-96%) had viral load suppression. Based on viral load recategorisation of data from transgender women and genderqueer participants, 53 (58%; 47-58) of 92 reported awareness of their HIV status, of whom 50 (94%; 84-99) reported using ART, of whom 46 (92%; 81-98) had viral load suppression. HIV-positive MSM aged 18-24 years had lower odds of being aware of their status than those aged at least 35 years (adjusted odds ratio [aOR] 0·34; 95% CI 0·13-0·92), as did HIV-positive MSM aged 25-34 years (aOR 0·26; 0·12-0·56). HIV-positive MSM aged 18-24 years also had a lower odds of having viral load suppression than those aged 35 years and older (aOR 0·35; 0·16-0·78), as did those aged 25-34 years (aOR 0·36; 0·19-0·67). No factors were significantly associated with awareness among transgender women and genderqueer individuals in multivariable models. INTERPRETATION: Our survey showed that HIV prevalence was high and the largest difference between our results and the 90-90-90 treatment targets was in HIV status awareness, indicating the need for improvements in engaging MSM (especially young MSM), transgender women, and genderqueer individuals in HIV testing services.
