Although many of the earliest cases of AIDS and HIV infection in Thailand were men who had sex with other men (MHSWM), transmission by heterosexual intercourse and needle sharing rapidly became dominant. This resulted in comparatively little attention being given to studies of risk behaviour and seroprevalence in groups of MHSWM with a consequent lack of information about these populations relevant to designing effective interventions. In the Partner Relations Survey, 3.3% of male Thais described their orientation as bisexual or homosexual, most probably an underestimate of the occurrence of same sex behaviour in Thai males. This paper briefly reviews the situation and presents results from a survey in the northeast of Thailand among men who have sex with men. Substantial levels of risk behaviour were found in MHSWM in the Northeast, with high rates of partner exchange and low levels of consistent condom use in insertive and receptive anal intercourse. Significant defects in AIDS knowledge existed implying a strong need for enhanced and expanded interventions in this community. Factors relevant to the design of interventions are highlighted and recommendations for further studies of MHSWM in Thailand are presented.
