Clinical Trial Summary
The purpose of this study is to assess how psychological stress and anxiety relate to bladder
sensitivity and to psychological burdens in people with overactive bladder and how this can
be measured effectively.
Description:
Overactive bladder (OAB) (i.e. urinary urgency, with or without urgency urinary incontinence,
frequency, and nocturia) affects 1 in 7 U.S. men and women and results in substantial
impairment to quality of life (QOL). To help self-manage and cope with OAB, many people adopt
compensatory bladder behaviors, such as restricting fluids, using containment products,
strategic planning and mapping restroom access, and even curtailing activities or travel
altogether, which further adversely impact QOL. These behaviors may be driven by anxiety and
stress related to urinary urgency and incontinence episodes as well as ensuing distress and
embarrassment. Prior research has linked anxiety and OAB: up to 40% of women and 30% of men
with OAB also have generalized anxiety disorder. The link between stress and OAB is less
studied. In animals, experimental stress can cause OAB-like symptoms and behaviors as well as
bladder and somatic hypersensitivity. In limited human studies, women with OAB may have
greater physiologic and psychologic stress reactivity, and acute stress may exacerbate
urinary urgency. However, how stress impacts on the bladder in the context of OAB or what
psychological factors drive compensatory behaviors that impair QOL in OAB remain unknown, as
there are no highly-controlled studies of anxiety-OAB links. Understanding these
relationships would be a critical advance to individualizing care of patients with OAB. The
proposed project will comprehensively investigate for the first time how stress, anxiety and
OAB interact, including the impacts on bladder sensitivity, urinary symptoms, and
compensatory bladder behaviors. The investigators propose a feedforward loop, whereby
increased OAB symptoms increase anxiety (via response to coping with stressful situations),
which in turn increases OAB symptoms (via increased bladder sensitivity). The study further
proposes that compensatory behaviors are driven by anxiety-related learning processes that
help perpetuate this relationship. The team will test the hypotheses in a sample of men and
women with OAB and healthy controls. Aim 1 will test the hypothesis that acute,
experimentally induced psychological stress will be more strongly associated with increased
bladder sensitivity in OAB patients than in controls, using a novel bladder sensation meter
with oral hydration and stress induction procedures. Aim will test the hypothesis that
psychological stress and anxiety will have concurrent and lagged effects on day-to-day
urinary symptoms that are stronger in individuals with OAB than in controls, using an
ecological momentary assessment approach (7-day electronic diary) to examine prospective
associations between everyday perceived stress, anxiety and urinary symptoms. Aim 3 will test
the hypothesis that compensatory behaviors (i.e. coping) used at the time of voiding will be
associated with subsequent reductions in anxiety levels, using a 3-day sensation-related
bladder diary that captures concurrent bladder behaviors and anxiety symptoms as well as
lagged symptoms 30 minutes post-void. Delineating these relationships and patterns will allow
for identification of potentially modifiable factors or areas for intervention.
