Introduction and hypothesis
Overactive bladder (OAB) syndrome is common urological condition, usually underdiagnosed and difficult to identify. The screening of lower urinary tract symptoms (LUTS) through patient self-administered questionnaires can be useful not only for timely identification of these patients but to implement early interventions for symptoms and their implication in a patients’ quality of life (QOL). Our objective was to assess the prevalence of OAB symptoms in patients attending general gynecology units in Barcelona, Spain, through a self-administered screening questionnaire.
Materials and methods
A cross-sectional, multicenter, observational, epidemiological study was carried out at general gynecology units of ten primary health centers in Barcelona, Spain. The study was conducted during a patient’s single visit through self-administered forms. Patients recorded sociodemographic data, medical history and comorbidities, and scored the presence and bother related to specific urological symptoms using the Cuestionario de Autoevaluación del Control de la Vejiga (CACV), the validated Spanish version of the Bladder Control Self-Assessment Questionnaire (B-SAQ). A score ≥6 on the symptoms scale of the CACV was taken as an indicator of suspected OAB.
One thousand and four women aged between 18 and 82 participated in the study. The overall prevalence of OAB was 11.8 %. A patient being >50 years was significantly associated with suspected OAB in comparison with the younger group [odds ratio (OR) 3.1 (2.1–4.7); p < 0,001]. Overactive bladder showed significant association with factors other than age, menopause, and previous urogynecological history, such as high body mass index (BMI) and parity.
The estimated prevalence of suspected OAB in patients attending general gynecological services in Barcelona is 11.8 %. Overweight or obese patients and those with three or more children were found to be at elevated risk for developing OAB.
