Table II. Distribution of risk factors according to continence status 4–12 years after 1st delivery.
Group A) women who were continent 4–12 years after 1st delivery; B) women who were continent 4 years after 1st delivery and 12 years after; C) women who were incontinent 4 years after 1st delivery and became continent 12 years after, and D) women incontinent 4–12 years after 1st delivery.
Three bivariate logistic regressions were performed between groups A versus B, C vs. D, and B vs. D. Significant results (p <0.20) are indicated by the index letter of the group concerned by the comparison.

UI: Urinary incontinence.
BMI at baseline: Body Mass Index in 2000 (four years after first delivery).
Delta BMI during follow-up: variation of Body Mass Index between 2000 and 2008 (between four and twelve years after first delivery).
Parity at baseline: parity four years after first delivery.
Additional parity during follow-up: number of subsequent pregnancies between 2000 and 2008 (between four and twelve years after first delivery).
