Background
The aim of this study was to estimate the prevalence and factors associated with Trichomonas vaginalis (T. vaginalis) among female sex workers (FSW) in Togo in 2017. A cross-sectional bio-behavioral study was conducted from August to October 2017 using a respondent-driven sampling method in four cities in Togo.
Method
A standardized questionnaire was used to record socio-demographic data and sexual behavior patterns. T. vaginalis detection by molecular biology tests was performed using Allplex STI Essential Assay which detect also 6 others micro-organisms. A blood sample was drawn and serological test using SD Bioline Duo VIH/Syphilis rapid test was performed for Human immunodeficiency virus (HIV) and syphilis testing.
Results
A total of 310 FSW with median age 25 years, interquartile range (IQR) [21–32 years] were included. The prevalence of T. vaginalis was 6.5% (95%CI = [4.1–9.9]) and, overall, prevalence of other STI ranged from 4.2% (95%CI = [2.3–7.2]) for N. gonorrhoeae to 10.6% (95% CI = [7.5–14.7]) for HIV. Binary logistic regression was conducted to assess factors associated with T. vaginalis infection. Living in Lomé (aOR = 3.19; 95%CI = [1.11–11.49]), having had sexual intercourse before the age of 18 (aOR = 5.72; 95%CI = [1.13–10.89]), and being infected with C. trachomatis (aOR = 3.74; 95%CI = [2.95–12.25]) were factors associated with T. vaginalis among FSW.
Conclusion
The prevalence of T. vaginalis infection using molecular test was low among FSW in Togo. Extensive studies are needed to confirm and to better understand the epidemiology of T. vaginalis among this population and in other populations in Togo.
