Obstetrics and Gynaecology, East Africa

Introduction: A decreased frequency of unprotected sex during episodes of concurrent relationships may dramatically reduce the role of concurrency in accelerating the spread of HIV. Such a decrease could be the result of coital dilution - the reduction in per-partner coital frequency from additional partners - and/or increased condom use during concurrency. To study the effect of concurrency on the frequency of unprotected sex, we examined sexual behaviour data from three communities with high HIV prevalence around Cape Town, South Africa.

Methods: We conducted a cross-sectional survey from June 2011 to February 2012 using audio computer-assisted self-interviewing to reconstruct one-year …

Obstetrics and Gynaecology, East Africa

Background. In South Africa, information on sex workers’ characteristics, sexual behaviour and health needs is limited. Current social, legal and institutional factors impede a safe working environment for sex workers and their clients.

Objectives. To describe characteristics and sexual behaviour of female, male and transgender sex workers, and assess their risk factors for unprotected sex.

Methods: Repeat cross-sectional surveys among sex workers were conducted in Hillbrow, Sandton, Rustenburg and Cape Town in 2010. Sex workers were interviewed once; any re-interviews were excluded from analysis. Unprotected sex was defined as any unprotected penetrative vaginal or anal sex with last two clients. …

Evaluating Audio Computer Assisted Self-Interviews In Urban South African Communities: Evidence For Good Suitability And Reduced Social Desirability Bias Of A Cross-Sectional Survey On Sexual Behaviour, Roxanne Beauclair, Fei Meng, Nele Deprez, Marleen Temmerman, Alex Welte, Wim Delva, Niel Hens

Obstetrics and Gynaecology, East Africa

Background: Efficient HIV prevention requires accurate identification of individuals with risky sexual behaviour. However, self-reported data from sexual behaviour surveys are prone to social desirability bias (SDB). Audio Computer-Assisted Self-Interviewing (ACASI) has been suggested as an alternative to face-to-face interviewing (FTFI), because it may promote interview privacy and reduce SDB. However, little is known about the suitability and accuracy of ACASI in urban communities with high HIV prevalence in South Africa. To test this, we conducted a sexual behaviour survey in Cape Town, South Africa, using ACASI methods.

Methods: Participants (n = 878) answered questions about their sexual relationships on …
