HIV, sexually transmitted infections, and related risk behavior among Cambodian men who have sex with men

Background:
Cambodia surveillance data suggest that HIV prevalence is declining among female sex workers and their clients; trends among men who have sex with men (MSM), however, are unknown. In 2000, 15% of MSM surveyed in Phnom Penh (PNP) were estimated to be HIV-infected. To obtain additional information, we conducted an integrated biological-behavioral survey among MSM in three Cambodian cities.


Methods:
From March to May, 2005, respondent driven sampling (RDS) was used to recruit MSM for a cross-sectional survey in PNP (the capital) and in two provincial cities, Battambang and Siem Reap. After providing informed consent, MSM were interviewed face-to-face using a standard questionnaire. Blood, urine, and rectal swabs were collected for syphilis, HIV, chlamydia, and gonorrhea testing.


Results:
Among 299 MSM from PNP and 249 from the provinces, 72% were younger than 25 years; 28% were aged 15-19. About 40% reported having sex with women in the past year. HIV prevalence was 8.9% in PNP and 0.8% in the provinces. In PNP, 18% of MSM had at least one sexually transmitted infection (STI) compared with 10% in the provinces. In PNP, 58% had sold sex in the past month compared with 41% in the provinces; consistent condom use in these encounters was higher in PNP (63%) than in the provinces (18%). Although more provincial MSM (94%) reported having receptive or insertive anal sex in the past month than PNP MSM (69%), very few (16%) used condoms consistently during anal sex (compared with 54% in PNP).


Conclusions:
HIV and STI prevalence among MSM was lower in the provinces than in the capital, despite a larger proportion of provincial MSM reporting recent anal sex and inconsistent condom useage. Interventions aimed at risk-reduction are urgently needed to prevent an HIV epidemic from emerging in this highly vulnerable population of provincial MSM.
