Coital bleeding and HIV risks among men and women in Cape Town, South Africa.

Background: South Africa has one of the world's fastest growing HIV epidemics. Genital bleeding during sexual intercourse may play a role in facilitating HIV transmission in South Africa.

Purpose: The purpose of this study was to examine the prevalence and sources of coital bleeding among men and women living in a Cape Town South Africa township.

Methods: A purposive sample of 464 men and 531 women completed anonymous street intercept surveys of HIV risk history and sexual behaviors.

Results: Thirty-one percent of men and 26% of women had a lifetime history of engaging in sexual intercourse that involved genital bleeding, and 21% of men and 16% of women reported coital bleeding in the previous 3 months. Over 75% of coital bleeding was attributed to menses. Across genders and controlling for demographic, sexual behavior, and life history factors, coital bleeding in the previous 3 months was associated with being an indigenous African, having multiple sexual partners, and higher rates of unprotected intercourse during that time period. People who reported coital bleeding were over 3 times more likely to have been diagnosed with a sexually transmitted infection even after controlling for having had genital ulcers.

Conclusions: Coital bleeding may be common in South Africa. Prevention messages that promote condom use or refraining from sex when there is genital bleeding are therefore needed.
