The odds of engaging in CSBI in the past 6 months were significantly higher among MSM who watched pornographic videos \u22653 times per month (adjusted Odds Ratio (aOR)\u202f=\u202f2.404, 95% confidence interval (CI): 1.598\u20133.617), and those who had a regular male sexual partner (aOR\u202f=\u202f1.900, 95% CI:1.369\u20132.637). The odds of inconsistent condom use with CSPI in the past 6 months were significantly higher among participants who disclosed sexual orientation (aOR\u202f=\u202f1.711, 95% CI: 1.010\u20132.898), those identified as bisexual or uncertain sexual orientation (aOR\u202f=\u202f2.228, 95% CI: 1.241\u20133.999), and those had sexual contact with \u201cboth student and non-student partners\u201d (aOR\u202f=\u202f1.897, 95% CI: 1.092\u20133.297). In contrast, participants with a high level of condom use self-efficacy (aOR\u202f=\u202f0.340, 95% CI: 0.212\u20130.657) and those who obtained human immunodeficiency virus (HIV) knowledge from the MSM communities (aOR\u202f=\u202f0.447, 95% CI: 0.245\u20130.815) had a significantly lower odds of inconsistent condom use.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>A high prevalence of web-based casual sexual behavior was observed among MSM college students, particularly among those who frequently viewed pornography or maintained a stable male sexual partner. Students who have sexual contact with non-student partners were associated with inconsistent condom use.
