BackgroundThis study was carried out to identify risk factors associated with urinary incontinence in women three months after giving birth.

MethodsUrinary incontinence before and during pregnancy was assessed at study enrolment early in the third trimester.
Incontinence was re-assessed three months postpartum.
Logistic regression analysis was used to assess the role of maternal and obstetric factors in causing postpartum urinary incontinence.
This prospective cohort study in 949 pregnant women in Quebec, Canada was nested within a randomised controlled trial of prenatal perineal massage.

ResultsPostpartum urinary incontinence was increased with prepregnancy incontinence adjusted odds ratio adj0R 6.44, 95% CI 4.15, 9.98, incontinence beginning during pregnancy adjOR 1.93, 95% CI 1.32, 2.83, and higher prepregnancy body mass index adjOR 1.07-unit of BMI, 95% CI 1.03,1.11.
Caesarean section was highly protective adjOR 0.27, 95% CI 0.14, 0.50.
While there was a trend towards increasing incontinence with forceps delivery adjOR 1.73, 95% CI 0.96, 3.13 this was not statistically significant.
The weight of the baby, episiotomy, the length of the second stage of labour, and epidural analgesia were not predictive of urinary incontinence.
Nor was prenatal perineal massage, the randomised controlled trial intervention.
When the analysis was limited to women having their first vaginal birth, the same risk factors were important, with similar adjusted odds ratios.

ConclusionsUrinary incontinence during pregnancy is extremely common, affecting over half of pregnant women.
Urinary incontinence beginning during pregnancy roughly doubles the likelihood of urinary incontinence at 3 months postpartum, regardless whether delivery is vaginal or by Caesarean section.
