Annual Incidence of New Women Presenting with Pelvic Floor Disorders in Europe: Focus on Pelvic Organ Prolapse, Urinary Incontinence, and Faecal Incontinence
Introduction
Pelvic floor disorders (PFDs) represent a significant public health concern in Europe, profoundly affecting women’s quality of life, social participation, and economic productivity. The primary conditions within this spectrum include pelvic organ prolapse (POP), urinary incontinence (UI), and faecal incontinence (FI). These disorders frequently co-occur and, while they are not life-threatening, they often lead to chronic disability, emotional distress, and increased healthcare utilization. Their incidence is influenced by various factors, most notably, aging, obstetric history, obesity, menopause, and certain lifestyle factors. Understanding the annual incidence and prevalence trends of PFDs in Europe is pivotal for developing prevention strategies, guiding policy interventions, and improving clinical outcomes.
Despite the high prevalence and social impact of these conditions, comprehensive and standardized data on annual incidence for each pelvic floor disorder by European country are scarce. Most available evidence is derived from prevalence studies, with annual incidence estimates often requiring extrapolation. This report presents an analytical synthesis of the most recent epidemiological data, major trends, and contributory risk factors regarding pelvic floor disorders among European women. It draws upon a broad array of reputable sources, including medical journals, global disease databases, WHO and European Union health statistics, and national-level surveys and registries.
Methodologies of Incidence Estimation in Pelvic Floor Disorders
Estimating the annual incidence of pelvic floor disorders in Europe is methodologically challenging. Variability in reported rates is primarily due to differences in:
Case definitions: UI, POP, and FI are often diagnosed via self-report, clinical examination, validated questionnaires (e.g., Pelvic Floor Distress Inventory [PFDI-20]), or clinical registries.
Study designs: Cohort, cross-sectional, and case-control studies predominate, with a few longitudinal population studies available for certain countries.
Sampling frameworks: Population-based, outpatient-clinic-based, or hospital-based data yield differing results.
Time frames and reporting: Some studies report cumulative incidence over several years, while others present annualized rates.
Cultural and reporting biases: The stigma around PFDs often results in underreporting, especially for FI and mild symptoms.
To counter these limitations, the most robust reports synthesise data from national health surveys (e.g., European Health Interview Survey [EHIS]), targeted epidemiological studies, and systematic reviews, adjusting for methodological quality and population representativeness.1,2
Conclusion
Pelvic floor disorders remain a substantial burden among European women, with millions affected annually by urinary incontinence, pelvic organ prolapse, and faecal incontinence. Urinary incontinence is the most common disorder, affecting up to half of all adult women and peaking in older populations and care homes. Pelvic organ prolapse prevalence varies widely, but symptomatic cases impact at least 3% to 14% of women, with the rate climbing with age and parity. Fecal incontinence, while less studied, impacts roughly 10% of adult women, also increasing with age, comorbidities, and prior obstetric trauma. Obesity, childbirth (especially vaginal or instrumental delivery), and menopause are key drivers of incidence and severity.
Annual incidence rates for PFDs generally range from 2–8% in adult European women, depending on disorder type and risk profile. Given the consistent upward trend driven by population aging, obesity, and extended longevity, targeted preventative policies, robust data systems, and multidisciplinary care models must be prioritized to mitigate the impact of pelvic floor disorders across Europe.
Calculation:
Based on an approximate total number of adult populations in Europe of 750,000,000 individuals and a female to male ratio of 51%, there are an estimated 382.5 million females in Europe.
Based on an estimated incidence of PFD in women in Europe of 2-8%, It would be expected that 7.65 - 30.6 million females are affected per year by PFD, hence, an average of 23,000,000 patients. Assuming a uniform incidence throughout the year, this means 63,000 new women being affected by PFD per day (2,625 per hour; 44 per minute).
Based on the lowest estimate of 2% these numbers would equate to 873/hour and 15/minute.
