To understand how household context factors impacted self-reported changes in solo and sexual behaviors in U.S. adults during early stages of the COVID- 19 pandemic, we conducted an online, nationally representative, cross-sectional survey of U.S. adults (N = 1010; aged 18–94 years; 62% response rate) from April 10–20, 2020. We used weighted descriptive statistics with Wilcoxon rank sign tests to understand the population prevalence and significance of self-reported changes (five-point scale: much less to much more) in 10 solo and partnered sexual behaviors. Ordinal regression was used to assess the impact of household predictor variables–including number of children at home, number of adults in home, partnership status (unpartnered, partnered and not living together, partnered and living together) and employment status (not working, employed not as essential worker, employed as essential worker). All models were adjusted for gender, age, sexual orientation, race/ethnicity, and residence location (urban, suburban, rural).All solo and partnered sexual behaviors showed some amount of significant change–increased activity for some and decreased for others–for U.S. adults during the pandemic. Not living with a partner was broadly associated with decreased affectionate partnered sexual behaviors; unpartnered adults reported increased sexting. Individuals not employed reported increased oral sex and increased consumption of sexually explicit materials as compared to non-essential workers. Number of children at home and household size were not significantly linked to self-reported behavior change. Ongoing sexual health-focused research should continue to focus on understanding how adults manage opportunities and constraints to their sexual lives in the context of a still-going pandemic. While many aspects of social life look more “normal” (e.g., many people have returned to their in-person offices and children are largely back in school), new and more-infectious strains of COVID-19 have proven that the pandemic may still yet impact daily living. Lessons learned from COVID need to include sexual health planning both for any future strains of COVID, as well as for future public health emergencies.

为了解家庭环境因素如何影响 COVID-19 大流行早期美国成年人自我报告的独奏和性行为变化，我们对美国成年人进行了一项具有全国代表性的在线横断面调查（N = 1010; 18-94岁；62% 的响应率）从 2020 年 4 月 10 日至 20 日。我们使用加权描述统计和 Wilcoxon 等级符号检验来了解 10 个人中自我报告变化（五分制：少到多）的人口流行率和显着性和伴侣的性行为。序数回归用于评估家庭预测变量的影响——包括家庭中的儿童数量、家庭中的成年人数量、伙伴关系状态（无伴侣、有伴侣但未同居、有伴侣且同居）和就业状态（未工作、受雇不是基本工人，而是作为基本工人受雇）。所有模型都针对性别、年龄、性取向、种族/民族和居住地（城市、郊区、农村）进行了调整。在大流行期间，对于美国成年人来说，所有单独和伴侣的性行为都显示出一定程度的显着变化——一些人的活动增加了，另一些人的活动减少了。不与伴侣同住广泛地与亲密伴侣性行为减少有关；没有伴侣的成年人报告性短信增加。与非必要工作者相比，未就业的个人报告称口交和色情材料消费增加。家里的孩子数量和家庭规模与自我报告的行为变化没有显着关联。正在进行的以性健康为重点的研究应继续侧重于了解成年人如何在仍在持续的大流行的背景下处理性生活的机会和限制。虽然社交生活的许多方面看起来更“正常”（例如，许多人已经回到他们的办公室，孩子们大部分都回到了学校），新的和更具传染性的 COVID-19 毒株已经证明，这种流行病可能仍会影响日常生活。从 COVID 中吸取的教训需要包括针对未来任何 COVID 毒株以及未来突发公共卫生事件的性健康计划。
