Abstract In early 2020, the novel coronavirus 2019 (COVID-19) spread across the United States and mitigation measures drastically affected the daily lives of Americans. In this study, we assessed the association between COVID-related relationship conflict and changes in intimate and sexual behaviors and experiences. Using data from an online nationally representative probability survey of 1,010 American adults in April 2020, we estimated the impact of coronavirus-related relationship conflict on changes in intimate and sexual behaviors among those in any type of romantic or sexual relationship (Nweighted=742). Further, we assessed the association between conflict and experience of orgasm and feeling emotionally close to partner. Among individuals in relationships, 34% reported some degree of conflict with their romantic partners due to the spread of COVID-19 and its related restrictions. Those experiencing frequent coronavirus-related conflict with their partner were significantly more likely to report decreased frequency of several solo and partnered intimate and sexual behaviors compared to those not experiencing any such conflict, exhibiting a dose-response trend among partnered sexual behaviors. Since the spread of coronavirus and associated social distancing measures in the United States, Americans have experienced escalations in conflict in their romantic partnerships, which was associated with changes to their intimate and sexual lives.

由COVID-19大流行引起的恋爱关系冲突以及在美国全国有代表性的样本中亲密和性行为的变化

摘要在2020年初，新型冠状病毒2019（COVID-19）遍及美国，缓解措施严重影响了美国人的日常生活。在这项研究中，我们评估了COVID相关的关系冲突与亲密和性行为及经历的变化之间的关联。利用2020年4月对1,010名美国成年人进行的全国代表性在线概率调查的数据，我们估算了冠状病毒相关关系冲突对任何类型的恋爱或性关系中人的亲密和性行为变化的影响（Nweighted = 742）。此外，我们评估了冲突与性高潮经历以及情感上与伴侣关系密切之间的关联。在有关系的个人中，由于COVID-19的传播及其相关限制，有34％的人表示与他们的浪漫伴侣有些冲突。与未经历过与伴侣发生频繁冠状病毒相关冲突的人相比，未经历过此类冲突的人更有可能报告几种单独和伴侣的亲密和性行为的发生频率降低，并且在伴侣的性行为中表现出剂量反应趋势。自从冠状病毒在美国传播和相关的社会疏远措施以来，美国人在恋爱关系中的冲突不断升级，这与他们亲密和性生活的改变有关。与未经历过与伴侣发生频繁冠状病毒相关冲突的人相比，未经历过此类冲突的人更有可能报告几种单独和伴侣的亲密和性行为的发生频率降低，并且在伴侣的性行为中表现出剂量反应趋势。自从冠状病毒在美国传播和采取相关的社会疏远措施以来，美国人在恋爱关系中的冲突不断升级，这与他们亲密和性生活的改变有关。与伴侣发生频繁与冠状病毒相关的冲突的人比未经历此类冲突的人更有可能报告几种单独和伴侣的亲密和性行为发生频率降低的情况，在伴侣的性行为中表现出剂量反应趋势。自从冠状病毒在美国传播和采取相关的社会疏远措施以来，美国人在恋爱关系中的冲突不断升级，这与他们亲密和性生活的改变有关。
