A total of 280 women were included in our study.
Descriptive analysis is exposed at table 1. In summary, mean age was 32,4 years (+/-5,4), with mean BMI of 26,8 kg/m2 (+/- 7,2). Type of delivery was eutocic in 213 cases (76.3%), with a mean of birth length of 7.1h (+/-4.9), 60 episiotomies (21.5%), 5 OASIS (1.8%) and mean birth weight 3215,9g (+/-584,6).
Results of main endpoint was: mean of ICIQ-SF (points) 1,2+/- 3.5, with a incidence of urine incontinence of 11,8% (33 cases) and fecal incontinence 0.4% (1 case).
We considered that one case of fecal incontinence was insuficient to look for risk factors, and we decided not to continue with the search for associations to fecal incontinence.
In the bivariant analysis , we compared differences in age, parity, type of anesthesia, type of delivery, perineal tear, BMI, birth weight, episiotomy and onset of labour on patients with and without UI at 6 month-postpartum. Of those, age (p=0,0049) and type of anesthesia (p=0,016) were stadistically related to UI.
In the multivariant analysis the model which the best AUC was the one that includes age, parity, type of anesthesia, type of delivery, perineal tear and BMI. However, according to our bivariant results, a multivariate logistic regression was performed taking age and type of anesthesia into account. Predictive model resulting was shown in figure 2.
