Introduction: 

In March 2020, Australian state and federal governments introduced physical distancing measures alongside widespread testing to combat COVID-19. These measures may decrease people's sexual contacts and thus reduce the transmission of HIV and other sexually transmissible infections (STIs). We investigated the impact of physical distancing measures due to COVID-19 on the sexual behavior of gay and bisexual men in Australia.

Methods: 

Between April 4, 2020, and April 29, 2020, 940 participants in an ongoing cohort study responded to questions to measure changes in sexual behaviors during the COVID-19 pandemic. Men reported the date they become concerned about COVID-19 and whether they engaged in sexual behavior with regular or casual partners or “fuckbuddies” in the 6 months before becoming concerned about COVID-19 (hereafter referred to as “before COVID-19”), and following the date, they become concerned about COVID-19 (hereafter referred to as “since COVID-19”). Before and since COVID-19 was based on individual participants' own perceived date of becoming concerned about COVID-19.

Results: 

The mean age of was 39.9 years (SD: 13.4). Most participants (88.3%) reported sex with other men during the 6 months before COVID-19. Of the 587 men (62.4%) who reported sex with casual partners before COVID-19, 93 (15.8%) continued to do so in the period since COVID-19, representing a relative reduction of 84.2%.

Conclusion: 

Gay and bisexual men in Australia have dramatically reduced their sexual contacts with other men since COVID-19. These behavioral changes will likely result in short-term reductions in new HIV and STI diagnoses. If sexual health screenings are undertaken before resuming sexual activity, this could present a novel opportunity to interrupt chains of HIV and STI transmission.

由于COVID-19而导致的身体走动扰乱了澳大利亚男同性恋和双性恋男性的性行为：对艾滋病毒和其他性传播传染病趋势的影响

介绍： 

2020年3月，澳大利亚各州和联邦政府采取了物理隔离措施，并进行了广泛的测试以对抗COVID-19。这些措施可能会减少人们的性接触，从而减少艾滋病毒和其他性传播传染病的传播。我们调查了由于COVID-19而造成的身体疏远措施对澳大利亚同性恋者和双性恋男人的性行为的影响。

方法： 

在2020年4月4日至2020年4月29日之间，正在进行的队列研究中的940名参与者回答了一些测量COVID-19大流行期间性行为变化的问题。男性报告了他们开始关注COVID-19的日期，以及在开始关注COVID-19之前的6个月内是否与正式或休闲伴侣或“ fuckbuddies”进行性行为（以下称为“ COVID-19之前”）。 ，自此之后，他们开始关注COVID-19（以下称为“自COVID-19起”）。在COVID-19之前和之后，其依据是各个参与者自己对COVID-19的关注日期。

结果： 

平均年龄为39.9岁（标准差：13.4）。大多数参与者（88.3％）报告说在COVID-19之前的6个月内与其他男性发生过性行为。在COVID-19之前报告过与休闲伴侣发生性关系的587名男性（62.4％）中，自COVID-19以来的这一期间，有93名男性（15.8％）继续这样做，相对减少了84.2％。

结论： 

自COVID-19以来，澳大利亚的男同性恋和双性恋男人已大大减少了与其他男人的性接触。这些行为改变可能会导致短期内减少新的HIV和STI诊断。如果在恢复性活动之前进行性健康检查，这可能会提供一个新的机会来中断HIV和STI传播链。
