Hook ups are sexual encounters that can include a variety of behaviours (e.g., kissing to intercourse) with no expectation of future contact or a committed relationship. Although hooking up is reported to be common on college campuses across the USA, little is known about whether the frequency of hooking up changes over the course of the college experience. Using cross-sectional data and the covariates alcohol use, gender and relationship status, we examined a synthetic cohort of undergraduate students (n = 1003) on rates of hooking up using (1) logistic regression and (2) an applied form of survival analysis. Whereas both analytic techniques produced similar results, survival analysis provided a more complete picture by showing an increase in the rate of hooking up that peaked between spring semester of the first year of college and autumn semester of the second year of college, followed by a gradual decline in hook up rates over subsequent semesters. Findings indicate that gender is significantly related to hooking up in the logistic regression analysis, with women reporting fewer hook ups; however, gender was not significantly related to hooking up in the survival analysis, indicating that there are no differences in the pattern across cohorts. Implications for promoting the sexual health of college students and future research are discussed.
一夜情是指包括各种行为（如亲吻到性交）的性接触，且不期望有未来的联系或确定的恋爱关系。尽管据报道在美国各大学校园里一夜情很普遍，但对于在大学期间一夜情的频率是否会发生变化却知之甚少。我们利用横断面数据以及饮酒、性别和恋爱状况等协变量，通过（1）逻辑回归和（2）一种应用形式的生存分析，研究了一个由1003名本科生组成的综合队列的一夜情发生率。虽然两种分析技术得出了相似的结果，但生存分析通过显示一夜情发生率在大学一年级春季学期到大学二年级秋季学期之间达到峰值，随后在后续学期中逐渐下降，从而提供了更完整的情况。研究结果表明，在逻辑回归分析中，性别与一夜情显著相关，女性报告的一夜情次数较少；然而，在生存分析中，性别与一夜情没有显著关系，这表明不同队列之间在模式上没有差异。本文还讨论了对促进大学生性健康的意义以及未来的研究方向。
