Obesity is a risk factor for pelvic floor disorders (PFDs), but limited information exists about the public awareness of this association.

Our primary objective was to assess awareness of the association between obesity and PFDs, comparing 2 cohorts of women with body mass index (BMI) <30 versus BMI ≥30.

We conducted a cross-sectional, survey-based cohort study. The survey included questions about demographics, height and weight self-assessment, and the risk of PFDs with obesity. Our primary outcome was the rate of women correctly identifying that obesity increases the risk of PFDs.

Of 377 eligible participants 272 (72.1%) completed the survey, with 266 analyzed. Of these, 159 (59.8%) had a BMI <30 and 107 (40.2%) had a BMI ≥30. Comparing the cohorts, the lower BMI cohort was older (mean age of 54.4 ± 18.3 vs 48.4 ± 17.5 years, P = 0.008) and had higher rates of graduate/professional school (35.2% vs 19.6%, P = 0.04). Both groups had similarly high rates of PFDs. There was no difference in identifying obesity as a risk factor for PFDs, although the lower BMI group was less likely to identify the implications of weight loss on urinary incontinence (UI) (27.7% vs 45.8%, P = 0.002). Controlling for potential confounders, obesity remained positively associated with knowledge about the implications of weight loss on UI (odds ratio, 2.5; 95% confidence interval, 1.5–4.4).

Few women identified the increased risk of PFDs with obesity. Obese women may have increased awareness of the implications of weight loss on UI.
