Men who have sex with men (MSM) remain one of the groups most at risk of HIV, particularly in countries with concentrated epidemics.

Men who have sex with men (MSM) remain one of the groups most at risk of HIV, particularly in countries with concentrated epidemics. Here, we review findings from behavioural research with MSM and discuss the potential of behavioural interventions.

Increasing sexual risk behaviour and HIV transmission among MSM is apparent. Although risk reduction strategies, including serosorting and strategic positioning, are being widely reported, these appear to offer limited protection to HIV-negative MSM. There are emerging HIV epidemics among MSM in low-income and middle-income countries, with reported high levels of HIV and sexual risk behaviour. Studies of African MSM report higher HIV prevalence than that in the adult male general population. Evidence of effective behavioural interventions is growing. However, further trials, incorporating biological endpoints, are required.
