OBJECTIVE: Long term effects of perineal @entity937 pose a major worldwide health issue for @entity1 during delivery. Since @entity6981 is related to major obstacles in obstetrics the aim of this study was to determine the relationship between @entity6981 and the occurrence of perineal @entity937 during vaginal delivery. METHODS: Between June 2013 and December 2013 pregnant @entity1 delivering after 37 weeks were recruited at one University hospital / tertiary care referral center in the course of this single-center, prospective cohort study. @entity6981 was assessed according to Nugent score method. Logistic-regression model was used to estimate odds ratios, adjusted for other risk factors to test the relationship between @entity6981 and the occurrence of 1st to 4th degree perineal @entity937 in @entity1 undergoing vaginal delivery. RESULTS: A total of 728 @entity1 were included, 662 analyzed with a complete Nugent Score of the vaginal swab. The prevalence of 1st to 4th degree perineal @entity937 was 35.8% (95% Confidence Interval (95%CI) = [32.2; 39.6]). The presence of BV was not significantly associated to the incidence of perineal @entity937 neither in the univariate analysis (crude Odds Ratio = 1.43; 95%CI = [0.79; 2.60]; p = 0.235) nor in the multivariate analysis (adjusted Odds Ratio = 1.65; 95%CI = [0.81; 3.36]; p = 0.167). Instrumental delivery was the most important risk factor for perineal lacerations. CONCLUSIONS: There is no evidence that @entity6981 is a risk factor for vaginal @entity937 . TRIAL REGISTRATION: ClinicalTrials.gov N   NCT01822782.
