Outline of Final Research Achievements

Bacterial vaginosis in pregnant women is a risk factor for premature birth. This study examined the relationship between pregnant women's lifestyle and the vaginal flora. First, we reviewed the literature. Second, we conducted observational research. It was suggested that the vaginal flora of pregnant women is related to work, intake of mushroom and Natto, use of panty-liner, use of shower toilet, and oral sex woman receives. The Nugent score and vaginal secretions pH are used to evaluate the vaginal flora. As a result, Nugent score and vaginal secretions pH was correlated, but the concentration of inflammatory cytokines in the vaginal secretions have been seen correlated more strongly with vaginal secretions pH than Nugent score. Accordingly, it is suggested that vaginal secretions pH is likely superior in evaluation to Nugent score of vaginal flora of pregnant women.
