Prevalence and incidence of pelvic organ prolapse, bowel and urinary dysfunction in the Integrated Woman's Health Program

Objective

Despite its high prevalence, little information is available on the natural history of pelvic floor dysfunction. We aimed to determine the prevalence, incidence and persistence of pelvic organ prolapse (POP), bowel and urinary symptoms over 6–7 years and its associated factors.

Study design

Women from a midlife cohort in Asia completed baseline and 6–7-year follow-up assessments. Sociodemographic characteristics and health conditions were obtained at baseline using validated questionnaires. Body mass index (BMI) and physical performance were objectively measured.

Main outcome measures

POP, bowel, and urinary dysfunction were measured using the Pelvic Floor Distress Inventory Short Form 20 at both timepoints. Binary logistic regression was used to analyze independent associations between baseline risk factors and prevalent, new, and persistent symptoms.

Results

Of the 1201 women enrolled at baseline, 62.3 % had symptoms in at least one domain of pelvic floor dysfunction. Poor sleep, poorer perceived health, and disability were associated with prevalent pelvic floor symptoms, while poor sleep doubled the adjusted risk of incident POP (adjusted odds ratio, aOR: 2.3, 95 % Confidence Interval: 1.4–3.9), bowel (aOR: 2.3, 1.4–3.7) and urinary (aOR: 1.7, 1.1–2.9) symptoms at the 6.6-year follow-up visit. Postmenopausal women had reduced risks of prevalent POP (aOR: 0.5, 0.3–0.7) and urinary symptoms (aOR: 0.4, 0.3–0.6), as well as a reduced risk of developing incident urinary symptoms (aOR: 0.4, 0.2–0.8). Good physical performance scores at baseline reduced the risk of incident bowel symptoms (aOR: 0.5, 0.2–0.9), whereas obesity increased the risks of persistent symptoms.

Conclusion

Poor sleep quality independently predicted incident pelvic floor dysfunction, while poor physical performance was associated with incident bowel symptoms.
