RESUMEN

HIV is highly prevalent in men who have sex with men (MSM) in West Africa. Many MSM in the region also have sex with women (MSMW). Accordingly, they are a potential bridge subpopulation for HIV transmission to women. We aimed to evaluate the proportions and characteristics of West African MSMW at high behavioral risk of acquiring HIV from male partners and transmitting it to female partners (HBRMF). The cohort ANRS-12324 CohMSM Study included 630 HIV-negative MSM in Burkina Faso, Cote d'Ivoire, Mali, and Togo. Among MSMW (i.e., with ≥ 1 female partner) in the cohort, HBRMF was identified using trajectory models based on seven at-risk sexual practices with male and female partners, including inconsistent condom use, multiple partnerships, and receptive same-sex anal intercourse. To assess the relevance of using trajectory models, we compared the proportions of participants who seroconverted during the cohort follow-up among those at HBRMF and those not at HBRMF. Factors associated with HBRMF were identified using a generalized estimation equation logistic regression model accounting for longitudinal data. Approximately half (47%) of the 304 MSMW (22% of all CohMSM study participants) were at HBRMF. This group accounted for 75% of the 28 HIV seroconversions observed during follow-up (p = 0.001). HBRMF was positively associated with being aged < 25 years (aOR 95% CI 1.67 [1.23-2.27]), being sexually attracted only to men (1.97 [1.38-2.78]), feelings of loneliness (1.92 [1.38-2.65]), and homonegative violence score (1.22 [1.05-1.41]). HBRMF was negatively associated with having had both stable and casual female partners in the previous 6 months (0.34 [0.20-0.60] vs. only a stable female partner). HBRMF tended to be negatively associated with having ≥ 4 sexual intercourses with female partners in the previous four weeks (0.54 [0.27-1.06] vs. no intercourse). Establishing official relationships with women might be a strategy for young and/or stigmatized MSMW to comply with social pressure to display a heterosexual lifestyle. However, this seems to increase the risk of HIV transmission to female partners. In the present study, almost half of MSMW were at HBRMF. This result stresses the need to adapt HIV research and prevention to MSMW and their female partners.

RESUMEN

In developed countries, vaccinations against hepatitis B (HBV), hepatitis A (HAV), and human papillomavirus (HPV) are often recommended to men who have sex with men (MSM) because of the risky sexual practices in which some engage. Vaccine coverage against these diseases is not optimal in France, probably due in part to vaccine hesitancy (VH). The overall aim of this survey among MSM was to estimate the prevalence of different grades of VH for these vaccines as well as of general VH (toward any vaccine). The specific objectives were to study the sociodemographic correlates of MSM specific and general VH and its association with vaccine uptake. A cross-sectional electronic survey (February-August 2022) collected information from 3,730 French MSM about their perceptions of HBV, HAV, and HPV and their related vaccines, to construct "specific VH" variables. Information about their past vaccination behaviors for any vaccine was used to construct a "general VH" variable, based on the World Health Organization definition. Almost 90% of MSM showed moderate or high specific VH for HBV, HAV, and/or HPV, and 54% general VH. A higher education level and comfortable financial situation were associated with lower grades of specific and general VH. Younger age was associated with less frequent specific VH and more frequent general VH. Specific VH, versus general, was more strongly associated with frequent self-reported non-vaccination against these three disease. Addressing their concerns about vaccines, improving their knowledge of vaccine-preventable sexually transmitted infections, and motivating them to get vaccinated are public health priorities.

RESUMEN

Loss to follow-up (LTFU) from HIV pre-exposure prophylaxis (PrEP) care compromises the goal of HIV elimination. We investigated the proportion of LTFU and associated risk factors among men who have sex with men (MSM) enrolled in a PrEP demonstration project in Burkina Faso, Côte d'Ivoire, Mali, and Togo. CohMSM-PrEP, a prospective cohort study, was conducted between November 2017 and June 2021 in community-based clinics. MSM aged 18 years or older at substantial risk of HIV infection received a comprehensive prevention package, including PrEP and peer education. LTFU was defined as not returning to the clinic for six months. Associated risk factors were investigated using a time-varying Cox's model. Of 647 participants followed up for a median time of 15 months, 372 were LTFU (57.5%). LTFU was associated with younger age (adjusted hazard ratio [95% Confidence Interval]; 1.50 [1.17-1.94]), unemployment (1.33 [1.03-1.71]), depression (1.63 [1.12-2.38]), and perceiving no HIV risk with stable male partners (1.61 [1.23-2.10]). Contacting peer educators outside of scheduled visits was protective (0.74 [0.56-0.97]). Our findings show that LTFU from PrEP care in West African MSM is a major challenge to achieving HIV elimination, but that the involvement of peer educators in PrEP delivery helps to limit LTFU by providing users with adequate support.

RESUMEN

BACKGROUND: Multiple barriers compromise pre-exposure prophylaxis (PrEP) engagement (i.e., use and adherence) in men who have sex with men (MSM). In low/middle-income countries, little is known about PrEP engagement in this population. In West Africa, the CohMSM-PrEP study was one of the rare interventions providing PrEP to MSM. We estimated PrEP use and correct adherence rates in CohMSM-PrEP, together with associated factors over time.  METHODS: CohMSM-PrEP recruited MSM in four community-based clinics in Mali, Côte d'Ivoire, Burkina Faso, and Togo. Quarterly follow-up included collecting socio-behavioral data, and providing a comprehensive HIV prevention package, PrEP (daily or event-driven), and peer educator (PE)-led counselling. Using repeated measures, multivariate generalized estimating equations models were used to identify factors associated with self-reported i) PrEP use and ii) correct PrEP adherence during participants' most recent anal intercourse (defined as four pills/week for daily users and 2 + 1 + 1 for event-driven users). RESULTS: Five hundred twenty participants were included with a median follow-up time of 12 months (IQR 6-21). Of the 2839 intercourses declared over the follow-up period, PrEP use was self-reported for 1996 (70%), and correct PrEP adherence for 1461 (73%) of the latter. PrEP use was higher in participants who also attended participating clinics outside of scheduled visits (adjusted odds ratio (aOR) [95% Confidence Interval, CI], p-value; 1.32[1.01-1.71], 0.040), and in those who practiced condomless anal sex (1.86[1.54-2.24], < 0.001). Correct adherence was higher in those who often contacted PE outside of scheduled visits (2.16[1.01-4.64], 0.047) and in participants who adopted receptive/versatile sexual positions with stable partners (1.36[1.03-1.81], 0.030). Instead, after an interaction effect between financial situation and regimen was tested, it was lower in event-driven users with a difficult/very difficult financial situation (comfortable/just making ends meet & daily, 4.19[2.56-6.86], < 0.001; difficult/very difficult & daily, 6.47[4.05-10.30], < 0.001; comfortable/just making ends meet & event-driven, 1.63[1.22-2.17], 0.001), and in participants who felt alone (0.76[0.58-0.99], 0.042). CONCLUSIONS: Community-based clinic attendance and PE contact outside of scheduled visits were both associated with higher PrEP engagement, but some socially and economically marginalized participants struggled with adherence. As scale-up continues in West Africa, we recommend implementing community-based interventions and providing extra support for vulnerable users to ensure adequate PrEP engagement.

RESUMEN

We investigated the rate and predictors of ineffective HIV protection in men who have sex with men (MSM) taking pre-exposure prophylaxis (PrEP) in a prospective cohort study from November 2017 to November 2020 in Mali, Côte d'Ivoire, Burkina Faso, and Togo. MSM had to be 18 years or older and at high risk of HIV infection to participate. They also received a comprehensive sexual health prevention package, including PrEP, in community-based clinics as part of the cohort study. Using socio-behavioral/clinical data, HIV protection during their most recent anal intercourse with a male partner was categorized as effective or ineffective (i.e., incorrect PrEP adherence and no condom use). Seventeen percent (500/2839) of intercourses were ineffectively protected for the 520 study participants. Predictors of ineffective HIV protection included being an event-driven user with financial difficulties, having a high alcohol misuse score, and not being a member of a community association. PrEP programs in West Africa must be tailored to socially vulnerable MSM who struggle to adopt PrEP.


RESUMEN: En este artículo hemos investigado la proporción y los factores predictivos de la protección ineficaz de VIH en un grupo de hombres, que tienen sexo con hombres (HSH) y que usan la profilaxis pre-exposición (PrEP). Se usaron los datos de un estudio de cohorte prospectivo realizado entre noviembre del 2017 y noviembre del 2020 en Mali, Costa de Marfil, Burkina Faso y Togo. Los participantes son HSH, de 18 años o más, y con alto riesgo de contaminación por el VIH. Estos han recibido un paquete completo de prevención en salud sexual incluyendo la PrEP en clínicas comunitarias como parte del estudio de cohorte. La protección contra el VIH durante la última relación sexual anal con un hombre fue categorizada como eficaz o ineficaz a partir de datos socio-comportamentales/clínicos (i.e. adhesión incorrecta à la PrEP y no utilización del condón). Concerniente a 520 participantes, 17% (500/2839) de las relaciones sexuales fueron protegidas de manera ineficaz. Entre los factores predictivos de la protección ineficaz contra el VIH se encuentran, el uso intermitente de la PrEP asociado a una situación financiera difícil, el consumo de alcohol y no ser miembro de una asociación comunitaria. Los programas de PrEP en África del Oeste, deben adaptarse a los HSH más vulnerables quienes podrían tener más dificultad para adoptar la PrEP.

RESUMEN

INTRODUCTION: Transgender identity is poorly accepted in France, and data on living conditions and the daily difficulties transgender people encounter are scarce. This lack of data reinforces their invisibility in social life, contributes to their stigmatisation and probably increases the burden of HIV infection, especially for HIV-positive transgender people (TRHIV). The main objective of the community-based research study ANRS Trans&HIV is to identify personal and social situations of vulnerability in TRHIV, the obstacles they encounter in terms of access to and retention in medical care, and their gender affirmation and HIV care needs. METHODS AND ANALYSIS: ANRS Trans&HIV is a national, comprehensive, cross-sectional survey of all TRHIV currently being followed in HIV care units in France. TRHIV women are exclusively included in the quantitative component, and TRHIV men in the qualitative component. Data are collected by community-based interviewers and will be analysed to explore patient care pathways and living conditions in the TRHIV population with regard to gender affirmation and HIV. Data collection began in October 2020 and should be completed in December 2021. The statistical analyses techniques used will be adapted to each of the study's objectives and to the type of data collected (cross-sectional (questionnaires) and retrospective (biographical trajectory)). The study's results will provide a greater understanding of TRHIV health needs in order to suggest possible national recommendations for comprehensive HIV and gender affirmation medical care. ETHICS AND DISSEMINATION: ANRS Trans&HIV was approved by Inserm's Ethical Evaluation Committee (no 20-694 on 12 May 2020) and is registered with the National Commission on Informatics and Liberty under number 2518030720. Potential participants are informed about the study through an information note provided by their attending HIV physician. All results published in peer-reviewed journals will be disseminated to the HIV transgender community, institutional stakeholders and healthcare providers. TRIAL REGISTRATION NUMBER: NCT04849767.

RESUMEN

OBJECTIVE: The study aimed to explore longitudinal interactions between homonegativity and sexual behaviors with female partners among HIV-negative West African men who have sex with men and women (MSMW). DESIGN AND METHOD: The community-based cohort CohMSM ANRS 12324 - Expertise France enrolled MSM in Togo, Burkina Faso, Côte d'Ivoire and Mali. Sociobehavioral data were collected every 6 months. Using 30-month follow-up data, a multiprobit analysis was performed to investigate the relationship between psychosocial and behavioral variables ex-ante (t - 1) and ex-post (t). RESULTS: MSMW (n = 326) accounted for half of all participants in CohMSM. They reported inconsistent condom use with women in 39% of visits. Perceived and internalized homonegativity at t - 1 tended to lead to sexual violence toward women at t (P < 0.1), which was associated with inconsistent condom use with them at t (P < 0.05). CONCLUSION: Given the high HIV prevalence in West African MSM, widespread condom-less sex with women in MSMW, and the aggravating effect of social and internalized homonegativity, more research in the MSMW subpopulation is needed to assess the risk of HIV bridging to women and to design support activities.

RESUMEN

BACKGROUND AND OBJECTIVES: In Mali, the non-governmental association (NGO) ARCAD Santé PLUS launched the CovidPrev program in response to the COVID-19 outbreak to ensure continuity of HIV care-related activities. This study aimed to identify individual and structural factors associated with mental health disorders (MHD) in the NGO's healthcare workers (HCW) in the early stage of the outbreak. METHODS: Data were collected between April 6 and 11, 2020 for 135 HCW in ARCAD Santé PLUS's 18 community-based HIV care centers. Outcomes corresponded to the PHQ-9, GAD-7 and ISI instruments for depression, anxiety and insomnia, respectively. A general mixture model with a negative binomial distribution was implemented. RESULTS: Most HCW were men (60.7%) and median age was 40 years IQR[33-46]. Symptoms of depression, anxiety and insomnia were declared by 71.9, 73.3, and 77% participants, respectively. Women were at greater risk of MHD. A lack of personal protection equipment and human resources, especially nurses, was associated with a high risk of MHD. CONCLUSIONS: Health policy must place non-front line HCW, including those in NGOs, at the core of the healthcare system response to the COVID-19 outbreak, as they ensure continuity of care for many diseases including HIV. The efficacy of public health strategies depends on the capacity of HCW to fully with and competently perform their duties.

RESUMEN

BACKGROUND: In West Africa, few HIV services target men who have sex with men (MSM). In 2015, the interventional cohort CohMSM started offering a community-based prevention package for MSM. Participants expressed interest in pre-exposure prophylaxis (PrEP) and their eligibility was demonstrated. In 2017, PrEP was added to services already offered as part of a new program, CohMSM-PrEP, which recruited CohMSM participants and new participants. We aimed to determine whether the introduction of PrEP as an additional prevention tool influenced the type of participant signing up for CohMSM-PrEP. METHODS: CohMSM-PrEP recruited HIV-negative MSM in community-based clinics in Mali, Cote d'Ivoire, Burkina Faso, and Togo. Quarterly follow-up included free clinical examinations, PrEP, HIV/sexually transmitted infection screening, peer education, condoms, and lubricants. Sociobehavioral data were collected every 3 months using face-to-face questionnaires. Our outcome was participant type: new participants vs CohMSM participants. Logistic regression was performed to identify the factors associated with being a new participant. RESULTS: Of the 524 MSM included in CohMSM-PrEP, 41% were new participants. After adjustment, multivariate analysis showed they were more socioeconomically disadvantaged with financial insecurity, social isolation-including isolation within the MSM community-and riskier sexual practices. CONCLUSION: The introduction of PrEP as an additional prevention tool and the use of peer-based outreach services over time influenced the type of participant signing up for a community-based HIV prevention cohort in West Africa. Adding these elements to existing interventions in Sub-Saharan Africa could be the key to reaching MSM marginalized from HIV prevention and care programs.

RESUMEN

The first COVID-19 cases in Mali were reported almost 1 month after the first case in the African continent. However, the outbreak continues to spread faster there than in other countries which, along with Mali, successfully tackled the 2014 Ebola outbreak in Africa. Given this context, specific actions targeting people living with HIV (PLWH) are needed to reinforce prevention. Community-based involvement is crucial to ensure continuity of care and treatment for PLWH. Furthermore, the health of frontline healthcare workers must take priority in any actions taken. The long-established trustful relationship between NGOs and PLWH in Mali is indispensable to disseminate key messages about COVID-19.

RESUMEN

OBJECTIVES: Whether regular HIV testing and counselling reduce risky sexual behaviours in African men who have sex with men (MSM) is still a matter for debate. We aimed to identify behavioural trajectories based on HIV risk exposure (HRE) and factors affecting their evolution. METHODS: Data were collected from 621 HIV-negative West African MSM (Mali, Cote d'Ivoire, Burkina Faso and Togo) included in a community-based cohort providing quarterly HIV testing and counselling. Sociobehavioural data were collected every 6 months. HRE was defined as reporting inconsistent condom use during receptive anal sex with male partners of unknown HIV status in the previous 6 months. Using 18-month follow-up data, group-based trajectory modelling helped identify behavioural trajectories and determine the factors associated with their evolution. HIV seroconversions (n=67) were specified in each group trajectory. RESULTS: Two distinct group trajectories were identified: medium-risk exposure MSM (ME-MSM) (61%, 6.4% of whom having seroconverted) and high-risk exposure MSM (HE-MSM) (39%, 17.5% of whom having seroconverted). A significant declining trend in the probability of reporting HRE over time ((95% CI)) was observed for HE-MSM (from 0.59 (0.48 to 0.70) at M0 to 0.31 (0.22 to 0.41) at M18), while it remained constant for ME-MSM (0.034 (0.0 to 0.079)). This can be explained by a progressive use of risk reduction strategies (less receptive anal sex, better knowledge of their partners' status and increasing condom use). Being younger, living in Burkina Faso, self-considering both a man and a woman and reporting a higher level of depression were all associated with HE membership. Among HE-MSM, HRE was higher in those practising transactional or group sex and those experiencing psychological harassment. CONCLUSIONS: Quarterly HIV testing and counselling seem to reduce risky sexual behaviours in HIV-negative MSM at greatest risk of infection. Specific support for young MSM, focusing on identity and mental health, is needed to strengthen HIV prevention in West African MSM.

RESUMEN

Understanding the dynamics of HIV infection in men who have sex with men (MSM) can help improve efficiency in existing prevention strategies. We aimed to identify and describe the sexual behaviors of MSM most at risk of HIV infection in West Africa. HIV-negative MSM were provided a quarterly preventive follow-up package in the community-based cohort CohMSM. They completed face-to-face sociobehavioral questionnaires every 6 months. This sub-study on 520 participants used a baseline, 6-, 12- and 18-month data cluster analysis to categorize two profiles (high risk [HRE] and moderate risk [MRE] of exposure to HIV) based on three risky sexual practices over the previous 6 months. HRE-MSM (61%) were more engaged in receptive practices, had a higher proportion of inconsistent condom use during anal sex, and reported more sexual partners than MRE-MSM (39%). The proportion of HIV seroconversions observed during the first 18 months of follow-up using sexual behavioral profiles (92% are HRE-MSM) was higher than using the three risky sexual practices separately. Factors associated with the HRE-MSM profile were being younger (18-21 years), reporting stigma, and having had no female partner while being attracted only to men. Our findings suggest that in order to identify MSM most at risk of HIV infection, several risky sexual practices need to be evaluated in a combined approach. Prevention programs should pay particular attention to younger MSM, and implement activities addressing questions of MSM identity and stigma in order to reduce the dynamic of HIV infection in Western African MSM.

RESUMEN

Although the HIV epidemic is generalized in West Africa, some population groups such as men who have sex with men (MSM), especially those engaged in transactional sex (TS), are thought to be particularly more vulnerable to HIV than others. However, few data are available to help identify their health-related needs with a view to implementing targeted prevention interventions. To fill this knowledge gap, we aimed to characterize MSM reporting TS (MSM-TS) and to identify factors associated with their sexual practices using data from the prospective cohort study CohMSM, which was conducted in Burkina Faso, Côte d'Ivoire, Mali and Togo. Three stigmatization sub-scores were constructed (experienced, perceived and internalized). The generalized estimating equation method was used for data analysis. Of the total 630 HIV-negative MSM recruited in CohMSM, 463, 410 and 244 had a follow-up visit at 6, 12 and 18 months, respectively. In a total of 1747 follow-up visits, 478 TS encounters were reported by 289 MSM-TS (45.9%). Of the latter, 91 regularly reported TS (31.5%), 55 (19.0%) stopped reporting TS after baseline, and 53 (18.3%) reported TS after baseline and 90 (31.1%) occasionally reported TS. The following variables, regarding the previous 6 months, were positively associated with TS: being younger (aOR[95%CI]:1.86[1.39-2.50]), less educated (aOR[95%CI]:1.49[1.09-2.03]), unmarried status (aOR[95%CI]:1.79[1.10-2.93]), satisfaction with current sex life (aOR[95%CI]:1.41[1.06-1.88]), group sex with men (aOR[95%CI]:2.07[1.46-2.94]), multiple male sexual partners (aOR[95%CI]:1.85[1.40-2.44]), receptive or versatile anal sex with male partners (aOR [95%CI]:1.48[1.12-1.96]), giving benefits in exchange for sex with a man (aOR[95%CI]:2.80[1.97-3.98]), alcohol consumption (aOR[95%CI]:1.44[1.08-1.93]) and drug use (aOR[95%CI]:1.82[1.24-2.68]) during sex, and finally experiencing stigmatization (aOR [95%CI]:1.15[1.07-1.25]). Condom use during anal sex (aOR[95%CI]:0.73[0.53-0.99]) was negatively associated with TS.

RESUMEN

Female sex workers (FSW) in mining sites are considered to be at very high risk of HIV infection. We aimed to characterize FSW at the Kôkôyô artisanal gold mining site in Mali, and identify factors associated with sex work using data from ANRS-12339 Sanu Gundo, a cross-sectional survey conducted in 2015 at the mine by ARCAD-SIDA, a Malian non-governmental organisation. People attending HIV-prevention activities were invited to participate in the quantitative and qualitative parts of the survey. A probit logistic regression was used for data analysis. Of 101 women who participated in the survey, 26.7% reported sex work as their main activity. Multivariate analysis showed that the probability of sex work as a main activity decreased by 1% per 1-year age increase (p = 0.020). Sex work was significantly more likely to be reported by single, divorced and widowed women (25.4% probability; p = 0.007). FSW were significantly more likely to be non-Malian (36.3% probability; p = 0.003), more likely to have a secondary activity (77% probability; p = 0.002), to work fewer than 56h/week (40.2% probability; p = 0.001) and to be in good health (12.1% probability; p = 0.016). In addition, being aware of the existence of sexually transmitted infection, using psychoactive substances, and having unprotected receptive anal sex during the previous six months were significantly associated with sex work (50.2%; p = 0.006; 45.6%, p = 0.003; and 7.4%, p = 0.016 probability, respectively). Qualitative findings confirm that poverty and boyfriends' refusal to use condoms remain key barriers to systematic condom use among FSW.

RESUMEN

Research on male clients of male sex workers (MCMSW) has been neglected for a long time globally. We aimed to characterize MCMSW and to identify factors associated with their sexual practices using data from the prospective cohort study CohMSM conducted in Burkina Faso, Côte d'Ivoire, Mali and Togo. Our study focused on HIV-negative men who have sex with other men (MSM), recruited between 06/2015 and 01/2018 by a team of trained peer educators. Scheduled study visits at 6, 12 and 18 months included medical examinations, HIV screening, risk-reduction counselling and face-to-face interviews to collect information on their sociodemographic characteristics, sexual behaviours, and HIV risk-reduction strategies (HIV-RRS). Three stigmatization sub-scores were constructed (experienced, perceived and internalized). Mixed-effects logistic regression was used for data analysis. Of the 280 participants recruited at baseline, 238, 211 and 118, respectively, had a follow-up visit at 6, 12 and 18 months. Over a total of 847 visits, 47 transactional sex (TS) encounters were reported by 38 MCMSW (13.6%). Of the latter, only one participant reported systematic TS (2.6%), 18 (47.4%) stopped reporting TS after baseline, while 6 (15.8%) reported TS after baseline. Thirteen participants (34.2%) reported occasional TS. After adjusting for country of study and age, the following self-reported factors were associated with a greater likelihood of being MCMSW: protected anal sex, exclusively insertive anal sex with male sexual partners, avoidance of sex after consuming psychoactive products and experiencing stigmatization (all during the previous 6 months). The majority of MCMSW in this study practiced HIV-RRS with male sexual partners, including engaging in protected anal sex, avoidance of sex when consuming psychoactive products, and practising exclusively insertive anal sex.

RESUMEN

OBJECTIVE: To explore the interest in taking PrEP among Western African men who have sex with men (MSM). METHODS: A cross-sectional survey was implemented at enrolment of HIV-negative MSM in a multiple centre community-based cohort study in four West African countries (Mali, Côte d'Ivoire, Burkina Faso, Togo). A standardised face-to-face questionnaire collected data on socio-demographic and behavioural characteristics over the previous 6 months. Descriptive analysis and multivariate logistic regression helped identify factors associated with the interest in taking PrEP. RESULTS: Of 564 participants, 87% were interested in taking PrEP. Interest in PrEP was associated with inconsistent condom use for anal sex (adjusted odds ratio (aOR): 2.11; 95% confidence interval (CI) 1.21-3.67), transactional sex (aOR: 2.02; 95% CI 1.11-3.71), searching for male sexual partners on the Internet in the previous month (aOR: 1.86; 95% CI 1.01-3.43), having a high level of self-esteem (aOR: 1.20; 95% CI 1.06-1.36), having at least one sexually transmitted infections at enrolment (aOR: 5.08; 95% CI 1.40-18.4) and not being aware of PrEP (aOR: 2.03; 95% CI 1.04-3.96). Participants having sex with HIV-positive male partners (aOR: 0.28; 95% CI 0.11-0.74), those being more sexually attracted to women than to men (aOR: 0.20; 95% CI 0.07-0.89) and those reporting psychological and material support from close friends (aOR: 0.33; 95% CI 0.15-0.73) were less interested in taking PreP. CONCLUSIONS: Western African HIV-negative MSM appear very interested in taking PrEP, especially those most at risk of HIV infection. PrEP implementation in a comprehensive prevention package should be considered urgently.

RESUMEN

OBJECTIVES: The aim of this article was to estimate HIV prevalence and the factors associated with HIV seropositivity in the population living and working at the informal artisanal small-scale gold mining (IASGM) site of Kokoyo in Mali, using data from the Sanu Gundo survey. Our main hypothesis was that HIV prevalence is higher in the context of IASGM than in the country as a whole. DESIGN: The ANRS-12339 Sanu Gundo was a cross-sectional survey conducted in December 2015. The quantitative survey consisted of face-to-face administration of questionnaires. Five focus groups were conducted for the qualitative survey. HIV prevalence was calculated for the sample, and according to the type of activity performed in IASGM. SETTINGS: The IASGM site of Kokoyo, one of the largest sites in Mali (between 6000 and 1000 people). PARTICIPANTS: 224 respondents: 37.5% were gold-diggers, 33% retail traders, 6.7% tombolomas (ie, traditional guards) and 9% female sex workers. The remaining 13.8% reported another activity (mainly street vending). PRIMARY AND SECONDARY OUTCOME MEASURES: HIV prevalence and HIV prevalence according to subgroup, as defined by their activity at the Kokoyo IASGM. A probit logistic regression was implemented to estimate the characteristics associated with HIV seropositivity. RESULTS: HIV prevalence for the total sample was 8% (95% CI 7.7% to 8.3%), which is much higher than the 2015 national prevalence of 1.3%Joint United Nations Programme on HIV/AIDS (UNAIDS). The probability of HIV seropositivity was 7.8% (p=0.037) higher for female non-sex workers than for any other category, and this probability increased significantly with age. Qualitative data revealed the non-systematic use of condoms with sex workers; and long distance from health services was the main barrier to accessing care. CONCLUSIONS: Integrated policymaking should pay special attention to infectious diseases among populations in IASGM zones. Bringing information/prevention activities closer to people working in gold mining zones is an urgent public health action.

RESUMEN

In addition to being the targets of frequent discrimination and violence,African men who have sex with men (MSM) are being hit hard by the HIV/AIDS epidemic. Although there is still insufficient research regarding the methods of HIV transmission in sub-Saharan Africa, several studies show that the prevalence of HIV infection among MSM is more than ten times higher than among the general population.
