This rapid surveillance report describes the sixth cycle of data collection (September-December 2018; AMIS 2018). The key indicators were the same as those previously reported for past AMIS cycles. The AMIS methodology has not substantively changed since AMIS 2017. MSM were recruited from a variety of websites using banner advertisements and email blasts. In addition, participants from AMIS 2017 who agreed to be recontacted for future research were emailed a link to AMIS 2018. Men were eligible to participate if they were aged \u226515 years, resided in the United States, provided a valid US ZIP code, and reported ever having sex with a man or identified as gay or bisexual. The analysis was limited to those who reported having oral or anal sex with a male partner in the past 12 months. We examined demographic and recruitment characteristics using multivariable regression modeling (P&lt;.05) stratified by the participants\u2019 self-reported HIV status. The AMIS 2018 round of data collection resulted in 10,129 completed surveys from MSM representing every US state, Puerto Rico, and Guam. Most participants were non-Hispanic White, aged between 15 and 24 years, living in urban areas in the southern United States, and recruited from general social networking websites. The plurality (4230\/10,129, 41.76%) of participants was in the youngest age group, 15-24 years, followed by the 40 years and older age group (3088\/10,129, 30.49%). The self-reported HIV prevalence was 6.08% (616\/10,129). Compared with HIV-negative or unknown status participants, HIV-positive participants were more likely to have had anal sex without a condom with a male partner in the past 12 months (adjusted odds ratio [aOR] 2.02, 95% CI 1.63-2.50) and more likely to have had anal sex without a condom with a serodiscordant or an unknown status partner (aOR 3.90, 95% CI 3.27-4.66). The reported use of marijuana in the past 12 months was higher among HIV-positive participants than among HIV-negative or unknown status participants (aOR 1.39, 95% CI 1.15-1.68). The reported use of methamphetamines and other illicit substances in the past 12 months was higher among HIV-positive participants than among HIV-negative or unknown status participants (aOR 3.42, 95% CI 2.41-4.87 and aOR 1.90, 95% CI 1.56-2.32, respectively). Most HIV-negative or unknown status participants (6838\/9513, 71.88%) reported ever taking an HIV test previously, and 52.51% (4995\/9513) of the participants reported undergoing HIV testing in the past 12 months. HIV-positive participants were more likely to report testing and diagnosis of sexually transmitted infections than HIV-negative or unknown status participants (aOR 3.50, 95% CI 2.89-4.24 and aOR 2.61, 95% CI 2.10-3.25, respectively).<\/jats:p>","DOI":"10.2196\/21812","type":"journal-article","created":{"date-parts":[[2021,1,17]],"date-time":"2021-01-17T12:59:31Z","timestamp":1610888371000},"page":"e21812","source":"Crossref","is-referenced-by-count":27,"title":["The Annual American Men\u2019s Internet Survey of Behaviors of Men Who Have Sex With Men in the United States: Key Indicators Report 2018"],"prefix":"10.2196","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0533-8257","authenticated-orcid":false,"given":"Sarah","family":"Wiatrek","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3245-0175","authenticated-orcid":false,"given":"Maria","family":"Zlotorzynska","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3225-6919","authenticated-orcid":false,"given":"Ramona","family":"Rai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7728-0587","authenticated-orcid":false,"given":"Patrick","family":"Sullivan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1133-4762","authenticated-orcid":false,"given":"Travis","family":"Sanchez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2021,3,4]]},"reference":[{"issue":"14","key":"ref1","first-page":"1","volume":"60","author":"Finlayson, T","year":"2011","journal-title":"MMWR Surveillence Summaries"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.2196\/publichealth.4314"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.2196\/publichealth.5476"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.2196\/publichealth.7119"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.2196\/11313"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.2196\/16847"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1007\/s10461-018-2168-4"},{"key":"ref8","unstructured":"HUD USPS ZIP code crosswalk files2017-02-15https:\/\/www.huduser.gov\/portal\/datasets\/usps_crosswalk.html"},{"key":"ref9","unstructured":"USPS ZIP code lookup2017-02-15https:\/\/tools.usps.com\/go\/ZipLookupAction_input"},{"key":"ref10","unstructured":"Centers for Disease ControlPreventionHiv infection risk, prevention, and testing behaviors among men who have sex with menNational HIV Behavioral Surveillance, 20 U.S. Cities20142021-02-16https:\/\/www.cdc.gov\/hiv\/pdf\/library\/reports\/surveillance\/cdc-hiv-surveillance-special-report-number-15.pdf"},{"issue":"166","key":"ref11","first-page":"1","author":"Ingram, DD","year":"2014","journal-title":"Vital Health Stat 2"}],"container-title":["JMIR Public Health and Surveillance"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/publichealth.jmir.org\/2021\/3\/e21812","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,6,30]],"date-time":"2026-06-30T17:30:01Z","timestamp":1782840601000},"score":1,"resource":{"primary":{"URL":"https:\/\/publichealth.jmir.org\/2021\/3\/e21812"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,3,4]]},"references-count":11,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2021]]}},"URL":"https:\/\/doi.org\/10.2196\/21812","relation":{"has-preprint":[{"id-type":"doi","id":"10.2196\/preprints.21812","asserted-by":"object"}]},"ISSN":["2369-2960"],"issn-type":[{"value":"2369-2960","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,3,4]]}}}
