To determine whether the pattern of change with regard to condom use and multiple sexual partners is influenced by gender or educational level. Findings from data collected from 1987 to 1990 about changes in condom use and multiple-partner activities are presented, based on telephone interviews with 9416 participants aged 18 to 44 years resident in central Scotland, UK. Change in patterns over time were modelled in a multivariate logistic regression using a linear interactive modelling program. Several models showing changes in the proportion of multiple-partner respondents and condom users yielded a complicated pattern of behavioural change in educational status and gender. There is a large difference in reported condom use and multiple sexual partners by gender, but the difference is decreasing over time. Better educated respondents increased their use of condoms while less educated respondents showed a decrease in the proportion of multiple partners.
