    Summary
    Against the background of an upward trend in newly diagnosed HIV infections and the increasing importance of heterosexual HIV transmission in Europe and Switzerland, the theory of planned behaviour has been tested and extended in a prospective study on condom use in a community sample of heterosexual men. Nine hundred eighty-two Swiss men between the ages of 25 and 65 were surveyed using standardised questionnaires in two computer-assisted telephone interviews. The theory of planned behaviour proved to be able to predict condom use in sexual encounters with new and casual partners. Condom use was predicted by intention. Perceived behavioural control and attitude were significant predictors of intention, whereas the subjective norm was not. Thus, in line with other studies, the present study highlighted the somewhat limited explanatory power of the theory. By adding the socio-cultural variable "somatic culture” to the model, the proportion of explained variance of intention was increased from 36 to 45 per cent. In light of these findings, prevention efforts should be more differentiated and specific in order to meet the specificities of the different types of somatic culture of the men they are targeting
