From this group, 425 college students who reported engaging in casual heterosexual behaviors in the past year were included, of whom 53 (12.47%, 53\/425) engaged in high risky sexual behavior. The results of the multivariable logistic regression analysis indicated that the participants who accepted sexual behavior with men who had sex with men (MSM), those who involved in commercial sexual activities with monetary transactions in the past year were more likely to have engaged in high risky sexual behavior. Additionally, the participants who consistently used condoms during sexual activity with casual sexual partners and those who used condoms occasionally were less likely to have engaged in high risky sexual behavior.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This study identified several key factors associated with high risky sexual behavior among college students engaging in casual heterosexual experience.
