Kauntim mi tu, an integrated bio-behavioural survey (IBBS) of women and girls who sell and exchange sex (from here on referred to as FSW), and men who have sex with men and transgender women (from here on referred to as MSM/TG), was conducted to support the scale up of essential HIV prevention and treatment services for these populations. The survey was conducted in Port Moresby between June and November 2016 and used respondent-driven sampling (RDS) to recruit participants. Kauntim mi tu had two goals: 1) to conduct Papua New Guinea’s first population size estimations of FSW and MSM/TG; and 2) to collect representative bio-behavioural data about FSW and MSM/ TG in order to inform HIV and STI prevention and treatment services and policy.
- In total, 674 women and girls involved in the selling and exchanging of sex for goods, services or money participated in the study. The median age of FSW in Port Moresby was 27 years, with 28.0% aged 35 years or older.
- Prevalence of sexually transmitted infections (STI) was high and 52.1% of FSW had at least one STI (excluding HIV). The most prevalent infections were anorectal and genital chlamydia and were roughly equal (31.8% and 29.7%, respectively).
- A total of 400 MSM and TG participated in the study. The median age of MSM and TG was 27 years, with more than one-third (37.8%) between the ages of 15 and 24 years.
- Prevalence of sexually transmitted infections (STI) was high and 34.0% of MSM and TG had at least one STI (excluding HIV). Genital chlamydia was the most common STI (12.3%) followed by anorectal chlamydia was 9.6%.
