We investigated the incidence of and factors associated with LTFU among Zambian female sex workers (FSWs) in an HIV-incidence cohort from 2012 to 2017. Enrolled participants returned at month one, month three and quarterly thereafter. FSWs were considered LTFU if they missed six consecutive months, or if their last visit was six months before the study end date. Of 420 FSWs, 139 (33%) were LTFU at a rate of 15.7 per 100 person years. In multivariable analysis, LTFU was greater for FSWs who never used alcohol, began sex work above the age of consent, and had a lower volume of new clients. Our study appeared to retain FSWs in most need of HIV-prevention services offered at follow-up. specialized alcohol incidence studies prevention trials risk behaviour ZAMBIE 056 052 19 4 296-303 2020 1608-5906 https://www.documentation.ird.fr/hor/fdi:010080455 10.2989/16085906.2020.1836005 1608-5906 [F B010080455] https://www.documentation.ird.fr/hor/fdi:010080455 https://www.documentation.ird.fr/intranet/publi/2021/01/010080455.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2021-02-08 2025-02-24 fdi:010080455 fre
