In this study, we documented the perceived accuracy of U\u00a0=\u00a0U in Brazil in three different groups: PLHIV, HIV\u2010negative\/unknown cisgender gay\/bisexual men who have sex with men (GBM) and HIV\u2010negative\/unknown other populations (POP).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Adult (age\u00a0\u2265\u00a018y) Brazilians were recruited during October 2019 to complete a web\u2010based survey advertised on Grindr, Facebook and WhatsApp. Perceived accuracy of U\u00a0=\u00a0U was assessed with the question: \u201cWith regards to HIV\u2010positive individuals transmitting HIV through sexual contact, how accurate do you believe the slogan U\u00a0=\u00a0U is?\u201d Response options ranged from 1 (Completely inaccurate) to 4 (Completely accurate) plus a fifth option (I don\u2019t know what \u201cundetectable\u201d means). Participants\u2019 characteristics were described according to perceived accuracy of U\u00a0=\u00a0U. Logistic regression models assessed the factors associated with perceived accuracy of U\u00a0=\u00a0U (completely accurate vs. partially accurate\/inaccurate or completely inaccurate) by group.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of 2311 individuals accessing the questionnaire, 1690 (73.1%) met inclusion\/exclusion criteria and completed it. Of these, 347 (20.5%) were PLHIV, 785 (46.4%) GBM and 558 (33.0%) POP. More PLHIV perceived U\u00a0=\u00a0U as completely accurate (79.0%), compared to 44.2% GBM and 17.2% POP (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001). Among PLHIV, Black identity was associated with decreased odds of perceiving U\u00a0=\u00a0U as completely accurate while having a steady partner was associated with increased odds. Among GBM, being gay, having middle\/higher income, being a resident of state capital metropolitan areas and ever testing for HIV were associated with increased odds. Lastly, among POP, ever testing for HIV increased the odds of perceiving U\u00a0=\u00a0U as completely accurate.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>There was a significant difference in perceived accuracy of U\u00a0=\u00a0U across population groups. Accurate understanding of the slogan needs to be promoted in more vulnerable populations such as PLHIV of Black identity and GBM of lower income to maximize individual and societal prevention benefits. Moreover, broader understating of U\u00a0=\u00a0U among the general population can help decrease societal stigma towards PLHIV.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jia2.25630","type":"journal-article","created":{"date-parts":[[2020,11,6]],"date-time":"2020-11-06T15:20:22Z","timestamp":1604676022000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":38,"title":["A
