Proportion and predictors of loss to follow-up in a longitudinal cohort study of female entertainment and sex workers in Cambodia

The study estimated the proportion of loss to follow-up among female entertainment and sex workers in an HIV prevention intervention trial in Cambodia. The authors found that women with no living children and those who recently experienced food insecurity are more likely to be lost to follow-up. Women who were members of a prevention program for more than six months were more likely to stay in the study. This suggests that stabilizing women’s lives, including reducing food insecurity and creating communities of engagement for this population, will help them adhere to a study or intervention.
