In a random sample of undergraduate students, we aimed to: (1) establish the prevalence of choking and being choked; (2) examine demographic and situational predictors of being choked, and (3) examine demographic and situational predictors of choking someone. Participants: 4168 randomly sampled undergraduates at a large public U.S. university. Methods: A cross-sectional, confidential online survey. Results: We found that 26.5% of women, 6.6% of men, and 22.3% of transgender and gender non-binary participants reported having been choked during their most recent sexual event. Additionally, 5.7% of women, 24.8% of men, and 25.9% of transgender and non-binary participants reported that they choked their partner at their most recent event. Choking was more prevalent among sexual minority students. Conclusions: Choking is prevalent among undergraduate students; implications for college sexual health education are discussed.
