Urinary incontinence significantly increases during pregnancy, affecting over half of women by week 30. Parity, age, and BMI are key risk factors for this common pregnancy complication.

Area of Science:

  • Obstetrics and Gynecology
  • Urology
  • Epidemiology

Background:

  • Urinary incontinence (UI) is a common condition affecting women's quality of life.
  • Pregnancy is a known period of increased risk for UI, but incidence and prevalence data require further investigation.

Purpose of the Study:

  • To determine the incidence and prevalence of urinary incontinence during pregnancy.
  • To identify associated risk factors for UI in pregnant women.

Main Methods:

  • A large cohort study involving 43,279 women from the Norwegian Mother and Child Cohort Study.
  • Questionnaire data collected by week 30 of pregnancy, analyzing UI type, frequency, amount, and risk factors using logistic regression.

Main Results:

  • Prevalence of UI rose from 26% pre-pregnancy to 58% by week 30.
  • Parity was a significant risk factor (OR 2.0-3.5), with higher rates in parous women (67% vs. 48% in nulliparous by week 30).
  • Stress urinary incontinence was most common; age and BMI were also significant risk factors.

    • Conclusions:

    • Urinary incontinence prevalence significantly increases during pregnancy.
    • Parity, maternal age, and body mass index are associated with UI both before and during pregnancy.
