<![CDATA[Background: Perineal rupture is a complication of vaginal delivery that can cause pain, bleeding, infection, and impaired quality of life in postpartum mothers. This condition is influenced by various factors, including nutritional status and perineal length, which affect tissue elasticity and the ability of the perineum to withstand stretching during childbirth. However, studies evaluating these two factors simultaneously remain limited. Purpose: This study aimed to determine the relationship between nutritional status and perineal length and the incidence of perineal rupture in vaginal delivery. Methods: This study employed an analytical cross-sectional design and was conducted at Klinik Pratama Alfa Medika, Surabaya. The study subjects were postpartum mothers after vaginal delivery who met the inclusion and exclusion criteria. A total of 53 respondents were selected using a consecutive sampling technique. Data were collected from primary and secondary sources, including measurements, observations, and medical records, and were analyzed using the chi-square test with a significance level of p < 0.05. Result: The results showed that almost all respondents had normal nutritional status (81.1%), most respondents had normal/long perineal length (67.9%), and the majority of respondents experienced perineal rupture (73.6%). The chi-square test results showed p > 0.05 (p = 0.609) for the relationship between nutritional status and perineal rupture, while p < 0.05 (p = 0.003) was found for the relationship between perineal length and perineal rupture. Conclusion: Based on the findings of this study, it can be concluded that perineal length was associated with the incidence of perineal rupture in vaginal delivery, whereas nutritional status was not significantly associated with perineal rupture.]]>
