Epidemiology of urinary symptoms in the geriatric population.

As the US population ages, there is a growing need for information about the urologic health problems facing older adults. In conjunction with findings from clinical studies and basic research on biological mechanisms, the epidemiologic approach offers insights on the prevalence, etiology, and impact of these geriatric conditions. This information can provide the basis for planning health care services and intervention programs. The authors discuss trends associated with population aging and the challenges posed by the epidemiologic study of older adults. Also reviewed are current findings on the prevalence, incidence, and correlates of urinary incontinence and other common urologic symptoms.
