Introduction: Unintended pregnancies and abortion may be considered as occupational hazards for female sex workers (FSWs). As our understanding of contraceptive and abortion practices of Iranian FSWs is very limited, this study tries to assess the dynamics of contraception and abortion among this sub-population.
Methods: This survey was conducted in 2010, by recruiting 872 FSWs through facility-based sampling from 21 sites in 14 cities in Iran. Data were collected through face-to-face interviews using a pilot-tested standardized risk assessment questionnaire. We applied the logistic regression model to investigate the correlates of induced abortion among FSWs.
Results: Of the 863 participants with valid responses to the abortion variable, 35.3% (95% CI: 32.1-38.6) acknowledged ever induced abortion and the annual rate of abortion was estimated at 20.7 per 1000 women. Around 31.2% of FSWs reported no usual contraceptive use, 32.6% barrier method, 23.6% non-barrier modern contraception methods, and 12.5% dual protection. In our multivariable model, older age (Adjusted Odds Ratio (AOR) = 1.74, 95% Confidence Interval (CI): 1.02, 2.96), group sex (AOR = 1.92, 95% CI: 1.10, 3.35), history of travel for sex work (AOR = 1.55, 95% CI: 1.09, 2.20), sexual violence (AOR = 1.77, 95% CI: 1.25, 2.50), STIs in last year (AOR = 1.53, 95% CI: 1.09, 2.14), and accessing family planning services (AOR = 1.76, 95% CI: 1.24, 2.49) were significant predictors of lifetime abortion.
Conclusions: The reproductive health needs of Iranian FSWs are unmet and around one-third of FSWs reported induced abortion. Scaling-up comprehensive family planning services and empowering FSWs to have safer sex practices may help them to prevent unintended pregnancies and further risk of HIV transmission.
