  abstract = {{HIV}-incidence studies are used to identify at-risk populations for {HIV}-prevention trials and interventions, but loss to follow-up ({LTFU}) can bias results if participants who remain differ from those who drop out. {W}e investigated the incidence of and factors associated with {LTFU} among {Z}ambian female sex workers ({FSW}s) in an {HIV}-incidence cohort from 2012 to 2017. {E}nrolled participants returned at month one, month three and quarterly thereafter. {FSW}s were considered {LTFU} if they missed six consecutive months, or if their last visit was six months before the study end date. {O}f 420 {FSW}s, 139 (33%) were {LTFU} at a rate of 15.7 per 100 person years. {I}n multivariable analysis, {LTFU} was greater for {FSW}s who never used alcohol, began sex work above the age of consent, and had a lower volume of new clients. {O}ur study appeared to retain {FSW}s in most need of {HIV}-prevention services offered at follow-up.},
