A retrospective study was performed to determine the incidence of HIV seroconversion among repeat consultants attending the voluntary testing and counselling centre of the Institut Pasteur of Cambodia as well as factors associated with HIV seroconversion. From 1996 to 1999, 5541 repeat consultants were selected for the study. Exclusion criteria included being aged under 15 years, having initially tested positive or inconclusive and a time span of fewer than 30 days since the last test. In all, 276 persons had seroconverted to HIV, giving an incidence rate of 5.56 per 100 person-years. The seroconversion rate declined from 8.46% in 1996, to 3.06% in 1999 (chi 2 test for trend, p = 10(-5)). Among the risk factors analysed, 3 were significantly associated with lack of seroconversion: being a student (RR = 0.53, p = 0.032) or a civil servant (RR = 0.63, p = 0.012) and systematic condom use with causal partners (RR = 0.37, p = 10(-5)). The decline of HIV seroconversion among repeat consultants attending the VCT centre over the study period may reflect changes in risk behaviour and the beneficial impact of counselling.
