Aim: This research aims to identify the correlation between parity and premature rupture of membrane (PROM) incidence at KIA Sadewa Hospital in 2013. Methods: The research was observational analytic research with a cross-sectional design. The sampling employed total sampling. This research population was all women giving birth at KIA Sadewa Hospital from January to December 2013 who had complete data as many as 2,645 women. The samples used in this study were 2388 women with expected delivery and 257 women who experienced the PROM. The data were secondary data obtained from medical records and then analyzed in univariate and bivariate analysis using a chi-square test with p-value = 0.005. Results: Women giving birth at KIA Sadewa Hospital in 2013 were mostly multipara. The incidence of premature rupture of membrane at KIA Sadewa Hospital in 2013 indicated 9.7% of them experiencing the PROM and 90.3% not experiencing the PROM. Conclusion. There was a correlation between parity and the incidence of premature rupture of membrane at KIA Sadewa Hospital in 2013. There is a correlation between parity with the incidence of premature rupture of membrane at KIA Sadewa Hospital in 2013. Keywords: Parity, Premature Rupture of Membrane
