- Abstract
Background: The effective testing of sexually transmitted infections (STIs) requires sampling from potential infection sites. This study aimed to assess the choice, satisfaction, and performance of self-collected samples (SCS) from potential infection sites for STI testing among transgender women in Brazil. Methods: TransOdara was a multicentric, cross-sectional STI prevalence study conducted in 5 Brazilian cities. Using respondent-driven sampling, 1317 transgenderwomen 18 years or older were recruited. Participants completed interviewer-led questionnaires and provided swab samples from multiple sites (anorectal, oropharyngeal, genital) for Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and human papillomavirus (HPV) testing. Participants were given a choice of SCS or provider-collected samples (PCS) at each site. Results: Most participants selected SCS for anorectal (74.9%; 95% confidence interval [CI], 72.4-77.3) and genital (72.7%; 95% CI, 70.2-75.1) sites, whereas fewer chose for oropharyngeal samples (49.8%; 95% CI, 47.0-52.6). For future testing, most participants expressed a preference for SCS for genital (72.2%; 95% CI, 69.5-74.7) and anorectal (70.2%; 95% CI, 67.6-72.7) sites. There was no significant difference in the positive test results for CTand NG between SCS and PCS at anorectal and oropharyngeal sites, or for HPVat anorectal and genital (penile or neovaginal) sites. Conclusions: This study demonstrated a high level of acceptability and usability of self-sampling for STI testing among transgender women. A preference for SCSwas evident at the anorectal and genital sites, and the results of SCS were comparable to those of PCS. The findings suggest that multisite STI testing utilizing self-collection methods as a provided option can be effectively integrated into sexual health services for transgender women.
