The number of samples was 37 cases and 37 controls. Data analysis was carried out univariate and bivariate using the Odds Ratio test. The results showed that the factors associated with the incidence of prolonged first stageof labor were Age (p=0.403; OR=2.121), Education (p=0.627; OR=0.789), Parity (p=0.011; OR=3.544), Contraction (p= 0.000; OR=0.072), Fetal Weight (p=1,000; OR=1,000).
