Bacterial vaginosis has been associated with prematurity and other perinatal complications. However, the efficacy of the treatment for preventing such complications has not yet been well established. The objective of this study was to evaluate the impact of treatment for bacterial vaginosis on a low-risk population of Brazilian pregnant women, in order to prevent prematurity and other perinatal complications. Observational retrospective cohort study, at the Obstetric and Gynecology Department, Universidade Estadual de Campinas (Unicamp). Vaginal bacterioscopy results from 785 low-risk pregnant women were studied. Three different groups of women were identified: 580 without bacterial vaginosis during pregnancy, 134 with bacterial vaginosis treated using imidazoles (metronidazole, tinidazole, or secnidazole) during pregnancy, and 71 with bacterial vaginosis not treated during pregnancy. The diagnosis of bacterial vaginosis was based on Nugent's criteria, from the vaginal bacterioscopy performed during the first prenatal care visit. The frequency of prematurity was 5.5% among the women without bacterial vaginosis, 22.5% among those with untreated bacterial vaginosis and 3.7% among those with treated bacterial vaginosis.
