We sought to describe changes in the context and typology of sex work between the first (early) and past month (recent) of sex work among YFSW to inform HIV prevention programming for sex workers.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec002\">\n<jats:title>Methods<\/jats:title>\n<jats:p>We used data from a cross-sectional survey (April-November 2015), administered using physical location-based sampling to 408 cis-women, aged 14\u201324 years, who self-identified as sex workers, in Mombasa, Kenya. We collected self-reported data on the early and recent month of sex work. The analysis focused on changes in a) sex work context and typology (defined by setting where sex workers practice sex work) where YFSW operated, b) primary typology of sex work, and c) HIV programme outcomes among YFSW who changed primary typology, within the early and recent month of sex work. We analysed the data using a) SPSS27.0 and excel; b) bivariate analysis and \u03c72 test; and c) bivariate logistic regression models.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>Overall, the median age of respondents was 20 years and median duration in sex work was 2 years. Higher proportion of respondents in the recent period managed their clients on their own (98.0% vs. 91.2%), had sex with &gt;5 clients per week (39.3% vs.16.5%); were able to meet &gt; 50% of living expenses through sex work income (46.8% vs. 18.8%); and experienced police violence in the past month (16.4% vs. 6.5%). YFSW reported multiple sex work typology in early and recent periods. Overall, 37.2% reported changing their primary typology. A higher proportion among those who used street\/ bus stop typology, experienced police violence, or initiated sex work after 19 years of age in the early period reported a change. There was no difference in HIV programme outcomes among YFSW who changed typology vs. those who did not.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusions<\/jats:title>\n<jats:p>The sex work context changes even in a short duration of two years. Hence, understanding these changes in the early period of sex work can allow for development of tailored strategies that are responsive to the specific needs and vulnerabilities of YFSW.<\/jats:p>\n<\/jats:sec>","DOI":"10.1371\/journal.pone.0288717","type":"journal-article","created":{"date-parts":[[2023,7,25]],"date-time":"2023-07-25T17:36:27Z","timestamp":1690306587000},"page":"e0288717","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":4,"title":["Changes in context, typology and programme outcomes between early and recent periods of sex work among young female sex workers in Mombasa, Kenya: A cross-sectional study"],"prefix":"10.1371","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3277-7693","authenticated-orcid":true,"given":"Parinita","family":"Bhattacharjee","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shajy","family":"Isac","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helgar","family":"Musyoki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Gichangi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huiting","family":"Ma","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9235-0547","authenticated-orcid":true,"given":"Marissa","family":"Becker","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"Hontelez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8492-5470","authenticated-orcid":true,"given":"Sharmistha","family":"Mishra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"on behalf of the Transitions team","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2023,7,25]]},"reference":[{"issue":"2","key":"pone.0288717.ref001","doi-asserted-by":"crossref","first-page":"149","DOI":"10.1080\/13691058.2013.845692","article-title":"Circumstances, experiences and processes surrounding women\u2019s entry into sex work in India.","volume":"16","author":"LM McClarty","year":"2014","journal-title":"Culture, Health & Sexuality."},{"key":"pone.0288717.ref002","article-title":"Identifying changing trends in the sex work dynamics among female sex workers (FSWs) in India.","author":"B Rakshase","journal-title":"National AIDS Control Organisation (NACO) and Tata Institute of Social Sciences (TISS)"},{"issue":"8","key":"pone.0288717.ref003","doi-asserted-by":"crossref","first-page":"635","DOI":"10.1136\/sextrans-2013-051203","article-title":"Demographic changes and trends in risk behaviours, HIV and other sexually transmitted infections among female sex workers in Bangalore, India involved in a focused HIV preventive intervention.","volume":"89","author":"GC Jayaraman","year":"2013","journal-title":"Sexually Transmitted Infections"},{"key":"pone.0288717.ref004","doi-asserted-by":"crossref","first-page":"1494","DOI":"10.1007\/s10461-019-02410-1","article-title":"Changes Over Time in HIV Prevalence and Sexual Behaviour Among Young Female Sex-Workers in 14 Sites in Zimbabwe, 2013\u20132016.","volume":"23","author":"ST Chabata","year":"2019","journal-title":"AIDS and Behavior."},{"key":"pone.0288717.ref005","doi-asserted-by":"crossref","first-page":"413","DOI":"10.1136\/sti.2006.020982","article-title":"What happens to women who sell sex?
