Sexual behaviour data are crucial for understanding the spread of sexually transmitted diseases (STD).
Over a period (1987-1992) in which the HIV epidemic increased public awareness of safe sexual practices, we describe predictors of condom use, changes in condom use over time, and the estimated effects of these changes on the spread of STD.
Condom use reported by females aged 18-35 years with non-cohabiting partners was analysed using data from two cross-sectional postal surveys performed 5 years apart (1987 and 1992) on two separate representative samples of 10 000 subjects aged 18-60 years living in Norway.
A simple mathematical model was used to assess the effects of selection bias.
A more complicated model was used to predict the effects of condom use on the prevalence of STD in a population which includes a core group of highly sexually active subjects.
We found an increase in the prevalence of condom use in the latest intercourse from 14% to 20% with non-foreign partners and from 10% to 38% with foreign partners, from 1987 to 1992.
In a logistic regression model, low frequency of intercourse, high education, one lifetime partner, and late sexual debut were predictors for condom use.
