What is the prevalence of overactive bladder syndrome?
A. 8%Answer B
The EPIC study (Irwin et al.) estimated the prevalence of lower urinary tract symptoms, overactive bladder, urinary incontinence and lower urinary tract symptoms suggestive of bladder outflow obstruction. Lower urinary tract symptoms were common, experienced by an estimated 45% of individuals, with a smaller proportion thought to be suggestive of bladder outflow obstruction (21.5%). Approximately 8% were estimated to suffer from urinary incontinence and 11% from overactive bladder symptoms.
