Introduction: Few studies have investigated pelvic organ prolapse (POP) at a national level,especially diagnosed in a physical objective examination.

Objective?The aim of this study is to provide estimates of the prevalence and potential risk factors associated with POP based on Pelvic Organ Prolapse quantification system and the bother it imposes in a nationwide population-based sample of adult women in China.

Methods: We conducted a national cross-sectional study from February 2014 through March 2016. A nationally representative sample of 54,000 adults who were 20 years old or older were sampled using multi-stage, stratified, cluster sampling at six populous provinces in mainland China among participants of National Mass Screening on Breast and Cervical Cancers.POP was assessed using Pelvic Organ Prolapse Quantification (POP-Q) stage and validation questionnaires. Multivariable logistic regression was used to assess factors associated with each degree or bother POP.

Results:The prevalence of symptomatic POP (POP-Q stage II or higher) was 9.56%. Stage II POP was the most common (7.52%) and 6.88% involved anterior compartment. Incidence increased with age for all stages (P≤0.05). Minor or moderate bother were the most common responses that were reported for every stage of POP (9.72%). Only 0.08% of the participants reported that the condition had a severe impact on their quality of life. Older age, postmenopausal status, and multiple vaginal deliveries increased the odds of every kind of POP (p ≤ 0.05).

Conclusion: Based on physical objective examination, 1 in 10 adult women have been reported to complain about POP or bother POP and mainly involved anterior compartment. Older age, postmenopausal status, and multiple vaginal deliveries increased the odds of every kind of POP.
