Men who have sex with Men (MSM) are a key population in the transmission of Human Immunodeficiency Virus (HIV) infection. In Benin, there is a lack of strategic information to offer appropriate interventions for these populations who live hidden due to their stigmatization and discrimination. The objective is to identify contributing factors that affect HIV incidence in the MSM population. Study of a prospective cohort of 358 HIV-negative MSM, aged 18 years and over, reporting having had at least one oral or anal relationship with another man during the last 12 months, prior to recruitment. The monitoring lasted 30 months with a follow-up visit every six months. Univariate analyses and a Cox proportional hazards multivariate regression were used to examine the association between bio-behavioral, socio-demographic and knowledge-related characteristics with HIV incidence. The retention rate for the follow-up of the 358 participants was 94.5%. On the 813.5 person-years of follow-up, 48 seroconversions with an HIV incidence of 5.91 per 100 person-years were observed (95% CI: 4.46-7.85). Factors associated with the high risk of HIV were age (HR = 0.4; 95% CI: 0.2-0.8), living in couple (HR = 0.5 95% CI: 0.2-0.96) and the lack of condom systematic use with a male partner during high-risk sex (HR = 3.9; 95% CI: 1.4-11.1). HIV incidence is high within MSM population and particularly among young people. Targeted, suitable and cost-effective interventions for the delivery of the combination prevention package in an environment free of stigma and discrimination are necessary and vital for reaching the 90x90x90 target.

[Sexual Behaviours at Risk of HIV Infection among Male to Female Transgender People in Benin].

Bull Soc Pathol Exot 2020 ;113(3):298-305

Plan international Bénin, Cotonou, Bénin.

Transgender people are a population vulnerable to the human immunodeficiency virus (HIV) due to frequent adoption of risky sexual behaviours. To reorient prevention interventions in this population, this study aims to identify factors associated with high-risk sexual behaviours. It's a cross-sectional study. The subjects were recruited by driven respondents sampling throughout the country in December 2017. They included subjects who identified themselves as Male to Female transgender and who adopted such an image. The data were collected by questionnaire. The variables were multi-partnership and condom use during sex. Proportion comparisons were made with Pearson's Chi2 test and multiple logistic modeling was performed. The prevalence of multipartnership was 83.85% and the prevalence of condom use during last intercourse was 92.41%. Sexual risk behaviours were associated with age (P = 0.004), occupation (P = 0.000), education level (P = 0.025), family and friends' attitudes towards transgender status (P = 0.044) and HIV prevention knowledge level (P < 0.05). The factors identified should be integrated into transgender interventions in Benin with a focus on improving knowledge in HIV prevention.

Acceptability of pre-exposure prophylaxis (PrEP) among men who have sex with men (MSM) in Benin: a qualitative study.

In Benin, consistent condom use among men who have sex with men (MSM)  is relatively low and providing them with Pre-exposure prophylaxis (PrEP) could be of great relevance. We aimed to describe PrEP knowledge and intention to use it; identify key facilitators and barriers to PrEP; and describe the perceived impact of PrEP on unsafe sexual behavior. MSM, 18 years or older, HIV-negative or of unknown status, were enrolled in five cities of Benin. Intention to use PrEP was assessed through five focus groups (FG). Data were analyzed using manual thematic sorting. Thirty MSM (six per city) participated in the FG. Mean age (standard deviation) was 27.1 (5.0) years. All participants expressed the intention to use PrEP if made available. Facilitators of PrEP use were: availability of medication, safety, absence of constraints as well as freedom to have multiple sex partners and sex with HIV-positive friends. Barriers were: complex procedures for obtaining medication, size and taste of medication, cost of medication, poor PrEP awareness.. Eighteen men admitted that PrEP could lead to decrease in or even abandonment of condom use. In conclusion, MSM showed openness to use PrEP if available, although they recognized that it could lead to risk compensation.

A Behavioral and Serological Survey on HIV Prevalence Among Prisoners in Benin.

J Public Health Afr 2017 Jun 24;8(1):678. Epub 2017 Aug 24.

Cases of HIV are common in Benin, with infection rates varying according to socioeconomic and cultural factors, and by region. Certain segments of the population, such as prison inmates, sex worker clients and truck drivers are at high risk for HIV/AIDS. The aim of this study is to identify which behavioral and serological indicators contribute to the spread of HIV among prisoners. A total of 496 inmates from prisons located in all major cities in Benin were surveyed. Data was collected through interview sessions carried out using a questionnaire and through blood samples. The results show that most inmates are Beninese (83.5%), and the average age is 33 years (range: 14-80 years). No prisoner reported using a condom the last time they engaged in sexual intercourse. Blood exposure was found in 14.6% of inmates and HIV was detected in 1.4% of cases. Our analysis indicates that the length of detention and gender are factors that influence HIV status. However, age, education, nationality and HIV awareness had no significant effect on HIV prevalence among inmates. The results highlight the need to raise awareness in prisons about HIV. This can be achieved by strengthening communication strategies and by organizing HIV and sexually transmitted diseases information sessions for both prison officers and inmates.
