Associations between intravaginal practices and bacterial vaginosis in Kenyan female sex workers without symptoms of vaginal infections

Abstract

Bacterial vaginosis (BV) is highly prevalent among African women and has been associated with adverse pregnancy outcomes, sexually transmitted diseases, and HIV-1. GOAL:

The goal of this study was to analyze the relationship among intravaginal practices, bathing, and BV. STUDY DESIGN:

The authors conducted a cross-sectional study of HIV-1-seronegative Kenyan female sex workers without symptoms of vaginal infections. RESULTS:

Of 237 women enrolled, 206 (87%) reported vaginal washing using either a finger or cloth. Increasing frequency of vaginal washing was associated with a higher likelihood of BV (chi(2) test for trend, P = 0.05). In multivariate analysis, vaginal lubrication with petroleum jelly (odds ratio [OR] = 2.8, 95% confidence interval [CI] = 1.4-5.6), lubrication with saliva (OR = 2.3, 95% CI = 1.1-4.8), and bathing less than the median for the cohort (14 times/week; OR = 4.6, 95% CI = 1.2-17.5) were associated with a significantly higher likelihood of BV. CONCLUSIONS:

Modification of intravaginal and general hygiene practices should be evaluated as potential strategies for reducing the risk of BV.
