OBJECTIVE: To follow time trends in HIV seroprevalence in the general population of Quebec, using persons attending outpatient surgery services (OSS) as a proxy population. METHODS: From November 1990 to October 1992, sera from subjects attending the OSS of 19 collaborating hospitals distributed all over the province were tested for HIV antibodies when blood was collected for other purposes (anonymous, unliked study). Data on test results, year of birth, sex and region of residence were collected. All repeatedly positive EIA were confirmed by RIPA. RESULTS: Over this two-year period, 61428 sera have been collected. Of these, 18% were from patients living in Montreal and 44% from men. Median age was 37 years. Crude seroprevalence was 13.3 per 10000 (82/61428). Seroprevalence per 10000 was much higher in men than in women (25.2 vs 4.1, p < 0.001). When comparing the second year of data collection (Nov. 91-Oct. 92) to the first one, seroprevalence significantly increased in men living in Montreal (1.5% vs 0.7%, p = 0.03). After adusting for age, sex, area of residence (using the actual distribution of these variables in the province) and for the recent increase in men from Montreal, global seroprevalence was 17.1 per 10000 (11,182 HIV-infected in a population of 6,527,750). CONCLUSIONS: The rise in HIV seroprevalence in men from Montreal may either reflect increased transmission in the male population of this city or be due to a bias related to changes in attendance of OSS by HIV infected men during the study period. The reasons for this increase will be closely investigated in the next few months.
