Urinary incontinence in nulliparous women: results from a nationwide sample

View Poster


Urinary incontinence (UI) is a common problem in women, affecting approximately 30% of women in the US. Pregnancy and childbirth are known risk factors associated with UI. Less is known regarding rates of UI in nulliparous women. We aim to evaluate patient-reported urinary outcomes in nulliparous women in the US.


The NHANES database was queried for all women during the years 2007-2014. Only women that reported never having been pregnant were included in analysis. Demographic and gynecologic history was quantified amongst women. Multivariable logistic regression was performed to assess the effect of factors on urinary outcomes.
