Association between sexual role and HIV status among Peruvian men who have sex with men seeking an HIV test: a cross-sectional analysis

The Prevalence of HIV Among Men Who Have Sex With Men (MSM) and Young MSM in Latin America and the Caribbean: A Systematic Review

Young men who have sex with men (YMSM) under 25 years old are among the few populations with increasing numbers of new HIV infections in parts of the world where HIV incidence is declining overall. In this systematic review, we synthesize the literature on HIV prevalence among MSM in Latin America and the Caribbean focusing on YMSM. Results were stratified according to study population sampling method used (probability and non-probability based). Forty-seven studies from 17 countries were published in the last 10 years. Among studies using probability-based sampling method (N = 21), HIV prevalence among MSM ranged from 1.2 to 32.6%. HIV prevalence tended to increase over time in studies sampling at different time points. HIV prevalence among YMSM exceeded 5.0% in more than a half of studies (51%; N = 22/43). Our review corroborates the high and potentially rising incidence of HIV among YMSM and characterizes the region's greatest challenge to ending the epidemic.

Socio-demographic factors predicting HIV test seeking behaviour among MSM in 6 EU cities

Background

HIV testing is generally accepted as being the lynchpin of a prevention strategy to tackle the HIV epidemic among MSM. However, few studies have analysed in detail the factors that influence HIV test seeking behaviour.

Methods

The objective of this article is to analyse the relationship between HIV test seeking behaviour and individual, social and demographic factors in a sample of MSM recruited though a multi-centre bio-behavioural cross-sectional study. A multi-level analysis was conducted to identify factors associated with HIV test seeking behaviour.

Results

A total of 2400 men were included in the sample. Age, self-reported sexual orientation, residence, household composition, educational status and perceived homonegativity all seem to impact on test seeking behaviour.

Conclusions

The results suggest the need for more targeted testing promotion strategies among MSM that take structural and environmental factors into consideration, as part of a comprehensive public health strategy to address the HIV epidemic.

HPV knowledge, burden and genital wart location among heterosexually identified versus homosexually identified men who have sex with men in Lima, Peru: cross-sectional results from a cohort study

OBJECTIVES

The relationship between sexual practices, identity and role among Latino men who have sex with men (MSM) and HIV risk is the subject of ongoing investigation but less is known about how these aspects of sexuality relate to human papilloma-virus (HPV), an independent risk factor for HIV. This observational study investigated the relationship between HPV and sexual practices, identity and role as well as other sexually transmitted infection (STI)/HIV risk factors among HIV-negative heterosexually and homosexually identified Peruvian MSM.

SETTING

Community-based clinic for MSM in Lima, Peru.

PARTICIPANTS

756 subjects were screened based on inclusion criteria of: born anatomically male; age ≥18 years; had any anal intercourse with a man during the previous 12 months; residing in metropolitan Lima; HIV negative; willing to commit to twice-yearly clinic visits for 24 months; had not participated in an HIV or HPV vaccine study. 600/756 participants met the inclusion criteria and were enrolled, of whom 48% (284) identified as homosexual and 10% (57) as heterosexual, the basis of the analyses performed.

RESULTS

Compared with homosexually identified MSM, heterosexually identified MSM had completed fewer years of formal education and were less likely to have: anogenital HPV or visible anal warts; given oral sex to a man; or used a condom with their most recent female sexual partner (all p<0.05). Conversely, heterosexually identified MSM were more likely to have: visible penile warts; used a condom during last anal intercourse; smoked cigarettes; had transactional sex; and used drugs during sex in the previous month (all p<0.01). There was no difference found between heterosexually and homosexually identified MSM by syphilis or high-risk HPV prevalence.

CONCLUSIONS

HPV burden, wart type (penile vs anal) and select HIV/STI risk behaviours differed between heterosexually and homosexually identified Peruvian MSM. Understanding the implications of these differences can lead to tailored HIV/STI prevention interventions for heterosexually identified MSM.
