The Relationship between Overweight and Overactive Bladder Symptoms.

BACKGROUND: Several authors have investigated the relationship between obesity - assessed only by body mass index (BMI) - and overactive bladder (OAB) symptoms. OBJECTIVES: The objective of this study was to determine the relationship between body fat percentage (BFP) and the severity of OAB symptoms with an impact on quality of life. DESIGN: Cross-sectional study. The sample consisted of 206 overweight women; they were university students (BMI = 25.8 ± 3.0) with an average age of 30.6 ± 2.4 years. Body composition analysis was used, including assessment of BFP, visceral fat area (cm2/level), and other parameters. OAB symptoms were evaluated with an OAB questionnaire (OAB-q), voiding diary, and quality of life scale (I-QoL). RESULTS: Ninety women had a BFP >32% and 116 had a BFP 32% (p 32% were 95% more likely to have OAB than other young women with a BPF <32%.
