Abstract：Objective To evaluate the clinical features and risk factors for bacterial vaginosis. Methods The study was designed as a prospective ease-controlled study. Case group included 150 bacterial vaginasis (BV) patients, and control group consisted of 100 normal women. Results The mean age Of BV was 31.92±9.15. 66.7% of women with bacterial vaginosis noted odor, discharge. Some BV patients (17.3%) are asymptomatic. In 88.7 % of women with bacterial vaginosis, vaginal pH is more than 4.5. Vaginal clean degree is usually grade Ⅰ or grade Ⅱ (90.7%), Out of 14(9.3%) grade Ⅲ～ grade Ⅳ , 4 complicated with vulvovaginal candidiasis, 3 with trichomonal vaginitis, 7 with aerobic vaginitis. The risk factors associated with BV included: Panty liners used during intermenstruation (P =0.016), oral sexual habits (P = 0.003), vaginitis history (P = 0.001). Condom use was a protective factor (P = 0.000). Conclusion The prevalence of bacterial vaginosis is found in women during their reproductive age. Odor or discharge is main complaints, however some women are asymptomatie. Vaginal clean degree is usually grade Ⅰ or grade Ⅱ in BV. ff vaginal clean degree is grade Ⅲ or grade Ⅳ, it suggests that there is a mixed infection. Panty liners used during inter-menstruation, oral sexual habits, vaginitis history are risk factors for BV. Condom use is a protective factor.
