SO Int Conf AIDS. 1994 Aug 7-12;10(1):291 (abstract no. PC0089). Unique Identifier : AIDSLINE ICA10/94370082 AB OBJECTIVES: Data on the prevalence of HIV infection among homosexual men in The Netherlands are lacking. In this cross-sectional study the unique possibility exists to correct the prevalence estimate for selection bias related with the HIV test. To our knowledge this has not been done on a national level before. METHODS: Participants in the study including a blood test (n = 308), were recruited in 1991/1992 among 1134 male respondents of a non-HIV specific questionnaire without a blood test included in 1989 in the 'Gay Krant', a national magazine for homosexuals. Participants in the blood test in 1991/1992 were compared (bi- and multivariate) with the other respondents of 1989, on self-reported risk behavior and self-reported serostatus in 1989. On the basis of self-reported serostatus in 1989 the measured seroprevalence in 1991/1992 was corrected in a logistic model for selection bias connected with the blood test. Other studies indicate that readers of the Gay Krant possibly have a lower risk of HIV infection than homosexual men in general. RESULTS: Among the 308 participants in the blood test 20 were seropositive (prevalence 6.5%, 95% CI 4.0-10.0). Risk behavior showed to be high and increasing. Participation in the blood test was not related to self-reported serostatus, but was related to self-reported risk behavior in 1989. After correction, the HIV-prevalence in 1991/1992 among male readers of the Gay Krant is estimated to be 5.6% (95% CI 3.4-7.8). A recent aselect population study indicates that 4% of adult males in the Netherlands had recent homosexual contacts, so the estimated number of HIV-infected homosexual men in The Netherlands in 1991/1992 is estimated between 6500 and 15,000. CONCLUSIONS: It is possible to carry out seroepidemiological research among homosexual men with selection bias being assessed and corrected for in the prevalence estimate. The prevalence of HIV among homosexual men in The Netherlands is substantial, even outside of Amsterdam.
