【Objective】 To investigate influential factors on successful application of double balloon catheter for labor induction in the third trimester pregnancy. 【Methods】 The medical documents of 108 patients were reviewed retrospectively and the data were collected. Univariate and multivariate Logistic regression analyses were performed

in which the discharged results (success or failure) as dependent variables and characteristics (including age

parity

maternal body mass index (BMI)

engagement onset of head

et al) as independent variables were included. 【Results】 In univariate regression

the significant positive variables for outcome were parity and engagement onset of head

and the negative variables were weight

BMI

birth and weight. The variables entered the multivariate regression included age

parity

BMI

engagement onset of head. 【Conclusion】 The age

parity

BMI and engagement shows good prediction performance for prognosis of double balloon catheter for labor induction.
