Study Design: The authors interviewed by telephone 422 white Americans (WA) and 44 African Americans (AA) selected using random-digit dialing, and 135 AA selected from a listed sample of census tracks having a population of at least 40% AA. Results: After adjusting for lifetime numbers of vaginal sex partners, sex during menses was associated with self-reported history of chlamydial infection among women (WA: odds ratio [OR] = 3.9; confidence interval [CI]: 1.1, 14.0; AA: OR = 1.6; CI: 0.6, 4.2), Anal sex was associated with self-reported history of genital warts, genital herpes, hepatitis, and gonorrhea; douching with a twofold increase in self-reported pelvic inflammatory disease, Anal sex was most common in women with a history of same-and opposite-sex: partners. Conclusions: These data confirm the association of douching and anal sex with various STD and suggest that sex during menses is associated with chlamydial infection.
