BACKGROUND: Anal intercourse is an efficient mode of HIV transmission and
may play a role in the heterosexual HIV epidemics of southern Africa.
However, little information is available on the anal sex practices of
heterosexual individuals in South Africa. PURPOSE: To examine the
occurrence of anal intercourse in samples drawn from community and clinic
settings. METHODS: Anonymous surveys collected from convenience samples of
2593 men and 1818 women in two townships and one large city sexually
transmitted infection (STI) clinic in Cape Town. Measures included
demographics, HIV risk history, substance use and 3-month retrospective
sexual behaviour. RESULTS: A total of 14% (n = 360) men and 10% (n = 172)
women reported engaging in anal intercourse in the past 3 months. Men used
condoms during 67% and women 50% of anal intercourse occasions. Anal
intercourse was associated with younger age, being unmarried, having a
history of STI, exchanging sex, using substances, having been tested for
HIV and testing HIV positive. CONCLUSIONS: Anal intercourse is reported
relatively less frequently than unprotected vaginal intercourse among
heterosexual individuals. The low prevalence of anal intercourse among
heterosexual individuals may be offset by its greater efficiency for
transmitting HIV. Anal sex should be discussed in heterosexual HIV
