The potential for an increase in the transmission of Acquired Immune Deficiency Syndrome (AIDS) exists because the practice of sexual intercourse among unmarried individuals has increased in all age groups. Nonetheless, an earlier study in 1984 had found that the sexual activity and minimal condom use of college students had not changed significantly since a previous year. This study was conducted to replicate earlier studies and obtain current data for college students in the United States. College students (N=99) responded to a survey which requested each subject to list each partner with whom they had engaged in sexual intercourse, the year of the activity, the number of intercourse experiences, the number of times condoms were used, the number of anal intercourse experiences, and the number of times condoms were used. They were also asked in which year they learned that AIDS was transmitted sexually, and those who indicated that they had engaged in intercourse without a condom were asked why. The results supported research showing that college students' sexual behavior has increased in the last 15 years, and that even though the students are aware of AIDS, over 40% of them still do not use condoms half of the time that they have intercourse. The use of condoms decreased as the number of partners increased. The results of the study indicate that students need to be informed about the risks entailed in trusting partners' statements of prior sexual history. (ABL)
