title: [HIV testing in Denmark in 1993: were the tests relevant?].
abstract: In order to describe HIV-testing activity among adults in Denmark, a cross-sectional study was designed using an anonymous questionnaire, which was forwarded with all HIV-test results in a given two-week period in 1993. Notified first-time identified HIV-positive cases were used for comparisons. The response rate was 50%. A total of 996 women and 834 men were included, among whom 68% of men and 62% of women were classified as having a behaviour that put them at increased risk for acquiring HIV, p < 0.02. Women were younger than men, p < 0.001. Around 1/3 of both men and women had previously been HIV-tested, a proportion that increased with increasing risk for HIV, p < 0.00001 for trend. HIV-tested adults were younger and less frequently living in the Copenhagen area than the first-time identified HIV-infected persons reported to the mandatory national HIV-surveillance system. The overall HIV prevalence was 0.3%, being 0.5% among men and 0.2% among women. Estimates showed that the yearly number of first-time identified HIV-infections among tested homo/bisexual men per 10(5) men were 100 times as high as among the heterosexual population. Also, 12% of Danish homo/bisexual men had an HIV test per year, a proportion that was 2.3% among adult women and 1.8% among adult heterosexual men without i.v. drug use. The yearly test-activity decreases with increasing age among both men and women. In conclusion, studies among the HIV-tested population along with results from systematic surveillance of first-time identified HIV-infections are useful in order to estimate the frequency and the relevancy of HIV testing in the entire population. Also, these results may help when planning national information campaigns.
