Self-administered anonymous questionnaires were included in the nationwide gay magazines "Pan" and "Cock" with the object of revealing the needs and possibilities of improved health educational effort in prevention of sexually transmitted HIV infection among homosexual and bisexual men. This was undertaken in March 1988 to illustrate the utilization and satisfaction of various sources of safe sex. The investigation reveals that campaigns about safe sex have been of great interest among the section of the target group which an investigation of this type could attract. In particular, the general efforts made by the Danish Health Board have attracted attention in a very broad section of men with homosexual contacts. Among those who employ the offers specifically made for the target gay group, considerable satisfaction is expressed. Compared with this, the employment of and satisfaction with medical help are considerably less. The significance of connections with a series of sociodemographic and subcultural subgroups are illustrated. Only where the gay-specific information is concerned was a significant association observed between receipt of information and the replier's reproduction of the given information about the risks involved in use of condoms. As regards the significance of single sources for sexual behaviour, a non-significant tendency was observed for persons who had received gay-specific written information to have a lower sex risk than those who had not received this information. It is recommended that the campaign hitherto initiated should be continued with intensification of AIDS prevention among the hidden homosexual men and men with sexual contacts with both sexes.
