Introduction And Hypothesis:
Estimation on prevalence and distribution of pelvic organ prolapse (POP) signs in a general female population is difficult. We therefore developed and validated a prediction model and prognostic instrument.
Methods:
Questionnaires were sent to a general female population (45-85 years). A random sample underwent vaginal examination for POP (POPQ). A prediction model was developed using multivariate analysis and validated in a subgroup of participants.
Results:
Positive questionnaire-response rate was 46.8% (1,397 of 2,979). From the questionnaire group, 649 women were vaginally examined (46.5%). Prevalence of clinically relevant POP was 21%. Multivariate analysis demonstrated significantly higher odds ratios on the report of vaginal bulging, parity > or = 2 and a mother with POP. The receiver operating characteristic curve showed areas under the curve of 0.672 and 0.640.
Conclusions:
The prevalence of POP at or beyond the hymen could be estimated in a general female population using our prediction model with 17 questions and our POP score chart with eight questions.
