Limited data is available on risky sexual practices affecting sexually transmitted infections among female sex workers in Ecuador. Factors such as age, membership in an FSW association, and self-reported previous STI diagnosis were associated with engaging in risky sexual practices. Among this population of sex workers, increasing age and belonging to an FSW association were linked to a higher likelihood of risky sexual behavior with clients, highlighting the importance of engaging with FSW organizations to reduce the burden of STIs.
Background There are limited published data on factors related to risky sexual practices (RSP) affecting sexually transmitted infections (STIs) among female sex workers (FSWs) in Ecuador. Methods Cross-sectional study of FSWs presenting for a consultation in a primary health care centre during 2017. A questionnaire was administered to collect information on RSP and potential risk factors including age, membership of an FSW association, self-report of previous STI diagnosis, previous treatment for suspected STI and temporary migration for sex work. Associations between RSP and potential risk factors were estimated by logistic regression. The proportion of STI was estimated from vaginal swabs by real-time PCR for four sexually transmitted pathogens (Neisseria gonorrhoeae, Trichomonas vaginalis, Chlamydia trachomatis, and Mycoplasma genitalium). Results Of 249 FSWs recruited, 22.5% had reported RSPs at least once during sex work. Among FSWs reporting unprotected vaginal sex in the previous three months, 25.5% had at least one other RSP type. 17.6% (95%CI 13.3-22.8) had at least one active STI. Prevalence of co-infections was 2.4% (95%CI 1.1-5.2). In multivariable analysis, RSP was associated with age (adjusted OR 1.06; 95%CI 1.02-1.10), membership of an FSWs association (aOR 3.51; 95%CI 1.60-7.72) and self-reported previous STI (aOR 3.43; 95%CI 1.28-9.17). Conclusions Among a population of female sex workers with high proportion of STIs, increasing age and belonging to an FSWs association was associated with a higher likelihood of engaging in RSP with clients. Engaging with FSWs organisations may reduce the burden of STI among sex workers.
