Vaginal practices of HIV-negative Zimbabwean women.

ABSTRACT

BACKGROUND: Vaginal practices (VPs) may increase HIV risk by injuring vaginal epithelium or by increasing risk of bacterial vaginosis, an established risk factor for HIV. METHODS: HIV-negative Zimbabwean women (n = 2,185) participating in a prospective study on hormonal contraception and HIV risk completed an ancillary questionnaire capturing detailed VP data at quarterly followup visits for two years. RESULTS: Most participants (84%) reported ever cleansing inside the vagina, and at 40% of visits women reported drying the vagina using cloth or paper. Vaginal tightening using cloth/cotton wool, lemon juice, traditional herbs/powders, or other products was reported at 4% of visits. Women with ≥15 unprotected sex acts monthly had higher odds of cleansing (adjusted odds ratio (aOR) 1.17, 95% CI 1.04-1.32). Women with sexually transmitted infections had higher odds of tightening (aOR 1.42, 95% CI 1.08-1.86). CONCLUSION: Because certain vaginal practices were associated with other HIV risk factors, synergism between VPs and other risk factors should be explored.
