Abstract

BACKGROUND

The Undetectable=Untransmittable (U=U) message has been promoted since it was demonstrated that viral suppression through HIV treatment prevents sexual transmission between serodiscordant partners (HIV treatment as prevention). Our study assessed familiarity with, perceived accuracy of, and willingness to rely on U=U in a national sample of gay and bisexual men in Australia.

METHODS

We conducted a national, online cross-sectional survey in April-June 2021. Eligible participants were gay, bisexual and queer men and non-binary people who lived in Australia. Logistic regression was used to identify factors associated with familiarity, perceived accuracy and willingness to rely on U=U (by having condomless sex with a partner with HIV who has an undetectable viral load).

RESULTS

Of 1280 participants, most were familiar with U=U (1006/1280; 78.6%), the majority of whom believed U=U was accurate (677/1006; 67.3%). Both familiarity and perceived accuracy were higher among participants living with HIV, followed by pre-exposure prophylaxis (PrEP) users, HIV-negative participants not taking PrEP, and untested/unknown status participants. Knowing at least one person living with HIV, among other factors, was associated with familiarity and perceived accuracy of U=U; and familiarity was associated with perceived accuracy. Among participants familiar with U=U, less than half were willing to rely on U=U (473/1006; 47.0%). Familiarity with U=U and knowing at least one person living with HIV were associated with willingness to rely on U=U, among other factors.

CONCLUSIONS

We found familiarity with U=U was associated with perceived accuracy and willingness to rely upon it. There is an ongoing need to educate gay and bisexual men (particularly HIV-negative men) about U=U and its benefits.

摘要

背景

自从通过 HIV 治疗抑制病毒从而防止血清不一致的伴侣之间的性传播(HIV 治疗即预防)被证实以来,“无法检测即无法传播”(U=U)的信息已经得到了推广。我们的研究评估了澳大利亚全国范围内男同性恋和双性恋男性群体对 U=U 的熟悉程度、感知准确性和依赖意愿。

方法

我们在 2021 年 4 月至 6 月期间进行了一项全国性的在线横断面调查。合格的参与者为居住在澳大利亚的男同性恋、双性恋和酷儿男性以及非二进制人群。逻辑回归用于识别与熟悉程度、感知准确性和依赖 U=U(与 HIV 病毒载量无法检测的伴侣进行无保护性行为)的意愿相关的因素。

结果

在 1280 名参与者中,大多数人熟悉 U=U(1006/1280;78.6%),其中大多数人认为 U=U 是准确的(677/1006;67.3%)。熟悉 U=U 的参与者中,HIV 感染者、使用暴露前预防(PrEP)的人群、未接受 PrEP 的 HIV 阴性参与者以及未检测/未知状况的参与者比例较高。除其他因素外,了解至少一位 HIV 感染者与熟悉 U=U 以及对 U=U 的感知准确性有关;熟悉程度与感知准确性有关。在熟悉 U=U 的参与者中,不到一半(473/1006;47.0%)愿意依赖 U=U。除其他因素外,熟悉 U=U 和了解至少一位 HIV 感染者与依赖 U=U 的意愿有关。

结论

我们发现,对 U=U 的熟悉程度与感知准确性和依赖意愿有关。需要继续向男同性恋和双性恋男性(特别是 HIV 阴性男性)宣传 U=U 及其益处。
