Abstract:
PURPOSE: To examine the relationship between weight gain and the success of VBAC by using body mass index (BMI). To examine the relationship between weight gain and the success of VBAC by using body mass index (BMI). METHODS: The study compared clinical features taken from 112 patients who tried VBAC at our institute from January 2001 through December 2006. There were divided into two GROUPS: 92 patients for the success (82.1%) and 20 patients for the failure group (17.9%). Excluding 36 patients with no BMI data, we constructed Receive-operating characteristics (ROC) curve to make the optimum BMI value for the prediction of success of VBAC. Based on the BMI 26 or more, two groups of patient were surveyed the interrelation between weight gain and success of VBAC. RESULTS: Between success and failure group, the weight gain during pregnancy showed significant differences which are 11.2+/-4 kg of the success group and 13.2+/-5 kg of the other one (p<0.05) A survey on the availability of the BMI date to estimate success of VBAC, the criteria with the standard BMI 26 is not statistically valuable (p=0.837). By comparing normal weight and overweight based on BMI 26, some factors showed statistically significant discrepancies: number of prenatal visit, maternal weight gain, maternal weight at the time of delivery, use of oxytocin and birth weight. CONCLUSION: BMI value of 26 has limitations in using as an estimate criteria on success of VBAC. Patients, however, who had relatively small scale of weight gain, showed significant clinical factors to increased success rate of VBAC.
