Spontaneous and assisted vaginal deliveries were analyzed separately with and without the application of UFP. Odds ratios were adjusted in a multivariate logistic regression analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>Prevalence of UFP was 8.9% in spontaneous and 12.1% in assisted vaginal deliveries. UFP was associated with a higher incidence of shoulder dystocia in both spontaneous (adjusted odds ratio [adj. OR] 2.44, confidence interval [CI] 95% 1.23\u20134.84) and assisted vaginal deliveries (adj. OR 6.88 CI 95% 3.50\u201313.53). Fetal acidosis (arterial umbilical pH&lt;7.2) was seen more often after the application of UFP in spontaneous vaginal deliveries (adj. OR 3.18, CI 95% 2.64\u20133.82) and assisted vaginal deliveries (adj. OR 1.59 CI 95% 1.17\u20132.16). The incidence of 5\u2032-Apgar&lt;7 (adj.

A higher incidence of anal sphincter tears (AST) (adj.
