[Predictors of sexual behavior in a group of heterosexual university students at risk for AIDS in Montreal].

In order to evaluate the predictors of risky sexual behavior and AIDS, 573 male and female college students enrolled in French speaking universities in Montreal answered a questionnaire dealing with their sexual behaviors, from which an index of risks was computed (CASH). The analyses show that the best predictors of the CASH for men are associated to their sexual partner taking the pill, peer attitudes toward sexuality and individual sensation-seeking index. For women the best predictors of risky sexual behaviors are the perception of chances to catch AIDS, use of drugs or alcohol during coital behavior, peer group attitudes, personal sexual attitudes and using the pill as a contraceptive. These results suggest that risky sexual behaviors depend on complex processes associated to lifestyle and personality structures.
