Sexual assault perpetrated against older adults remains understudied. This research examined sexual assault incidents perpetrated against older women and men (aged 60+) reported to law enforcement. It compared these sexual assault incidents with those committed against middle-age (aged 40–59) and younger (aged 18–39) women and men. National Incident-Based Reporting System data (1992–2015) were analyzed using multinomial logistic regression models. Findings showed incidents involving an older woman, relative to a middle-age and/or younger woman, were significantly more likely to involve stranger perpetrators, occur at a private location, and involve additional violent crime or property crime. Incidents involving an older man, relative to a middle-age and/or younger man, were significantly more likely to involve offenders of more than one sex, older offenders, stranger perpetrators, and additional violent crime or property crime. Results are discussed in relation to prior work and future directions.

对老年人的性侵犯仍未得到充分研究。这项研究调查了向执法部门报告的针对老年女性和男性（60 岁以上）的性侵犯事件。它将这些性侵犯事件与针对中年（40-59 岁）和年轻（18-39 岁）女性和男性的性侵犯事件进行了比较。使用多项逻辑回归模型分析了基于国家事件的报告系统数据（1992-2015 年）。调查结果显示，与中年和/或年轻女性相比，涉及老年女性的事件更有可能涉及陌生人肇事者，发生在私人场所，并涉及额外的暴力犯罪或财产犯罪。与中年和/或年轻男子相比，涉及年长男子的事件明显更有可能涉及不止一种性别的罪犯，年长的罪犯、陌生人的肇事者以及其他暴力犯罪或财产犯罪。讨论结果与先前的工作和未来的方向有关。
