[The extent of HIV testing in the Norwegian population seen in relation to sex behavior]

To estimate the incidence of clinical HIV-testing and the association between testing and sexual habits, data from a 1992 population-based, anonymous survey of sexual behaviour were analysed. The sample size was 10,000 subjects between 18 and 60 years of age and the response rate was 48%. 15% of the males and 13% of the females reported having been HIV-tested at least once during the period 1985-92, and 1% of the sample four times or more. The incidence of testing has increased. However, a decrease in first time testing was observed after 1990. The best predictors of HIV-testing are the partner's test behaviour and the number of sexual partners during a lifetime.
