Hotspots were grouped into five strata (betting shops; car parks\/washes; bus stations\/taxi ranks; churches; and markets\/shopping streets) and day\/times when hotspots were frequented by men were listed. Within each stratum, three hotspots were randomly selected. Subsequently, 1\u2009day\/time was randomly selected for each hotspot. Men aged 20\u201335 were approached for participation and data was collected between July and October 2022. We describe participation in the survey, socio\u2010demographics, and sexual behaviours. Using logistic regression, we explored factors associated with knowledge of HIV status.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>339 men were approached, among whom 304 (90%) were eligible and 297 (98%) consenting to participate. Overall, 61% knew their HIV status. Adjusting for recruitment strata, knowledge of HIV status was similar by age (20\u201324: 56%; 25\u201329: 68%; and 30\u201335: 55%; <jats:italic>p<\/jats:italic>\u2009=\u20090.19). Among men reporting sex in the last month, men reporting no condomless sex were more likely to know their HIV status (78.2%) compared to men reporting one condomless sex partner in the past 1\u2009month (55.5%; age\u2010adjusted OR\u2009=\u20093.02; 95%CI 1.07, 8.55; <jats:italic>p<\/jats:italic>\u2009=\u20090.07). Knowledge of HIV status was lower among men who thought their friends were testing every 2\u20135\u2009years (48%; <jats:italic>n<\/jats:italic>\u2009=\u200912\/29) compared to those assuming that their friends tested more frequently (70.0%; adjOR\u2009=\u20090.28; 95%CI 0.08, 0.98; <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The time location sampling survey was acceptable among men, as evidenced by high participation. Overall, 40% of young men did not know their HIV status. A hotspot\u2010driven approach to delivering HIV testing services may prove effective at reaching men. Furthermore, time location sampling surveys should be explored as a tool to evaluate interventions targeting men.<\/jats:p><\/jats:sec>","DOI":"10.1111\/tmi.14128","type":"journal-article","created":{"date-parts":[[2025,5,24]],"date-time":"2025-05-24T09:33:57Z","timestamp":1748079237000},"page":"712-720","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Knowledge of <scp>HIV<\/scp> status among men aged 20\u201335\u2009years in Lusaka, Zambia: Findings from a pilot time location sampling survey in the \u201c<scp>Yaba Guy Che<\/scp>\u201d (for the guys) study"],"prefix":"10.1111","volume":"30","author":[{"given":"Mwelwa Muleba","family":"Phiri","sequence":"first","affiliation":[{"name":"Zambart  Lusaka Zambia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lucheka M.","family":"Sigande","sequence":"additional","affiliation":[{"name":"Zambart  Lusaka Zambia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chisanga","family":"Mwansa","sequence":"additional","affiliation":[{"name":"Zambart  Lusaka Zambia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ab","family":"Schaap","sequence":"additional","affiliation":[{"name":"Zambart  Lusaka Zambia"},{"name":"Department of Infectious Disease Epidemiology Faculty of Epidemiology and Population Health, London School of Hygiene and Tropical Medicine  London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sian","family":"Floyd","sequence":"additional","affiliation":[{"name":"Department of Infectious Disease Epidemiology Faculty of Epidemiology and Population Health, London School of Hygiene and Tropical Medicine  London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Loyd","family":"Kalekanya","sequence":"additional","affiliation":[{"name":"Zambart  Lusaka Zambia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charles","family":"Banda","sequence":"additional","affiliation":[{"name":"Zambart  Lusaka Zambia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Steve","family":"Belemu","sequence":"additional","affiliation":[{"name":"Zambart  Lusaka Zambia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Helen","family":"Ayles","sequence":"additional","affiliation":[{"name":"Zambart  Lusaka Zambia"},{"name":"Department of Clinical Research Faculty of Infectious and Tropical Diseases, London School of Hygiene and Tropical Medicine  London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Musonda","family":"Simwinga","sequence":"additional","affiliation":[{"name":"Zambart  Lusaka Zambia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernadette","family":"Hensen","sequence":"additional","affiliation":[{"name":"Department of Public Health Institute of Tropical Medicine  Antwerp Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,5,24]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/QAD.0000000000002321"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/jia2.25818"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/jia2.25855"},{"issue":"1","key":"e_1_2_11_5_1","first-page":"125","article-title":"Understanding barriers to HIV testing and treatment: a study of young men and healthcare providers in KwaZulu\u2010Natal and Mpumalanga","volume":"2019","author":"Sharma S","year":"2019","journal-title":"South African Heal Rev"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1186\/1744-8603-7-13"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/jia2.25517"},{"key":"e_1_2_11_8_1","unstructured":"MwansaC PhiriM BelemuS KalekanyaL BandaC SigandeL et al.Exploring barriers and facilitators to accessing HIV services among men aged 20\u201335\u2009years in Lusaka Zambia: findings from the Yaba Guy Che \u201cfor the guys\u201d study.
