Nocturia and Sleep Apnea

We are looking at a large sample of patients who presented to our sleep centers with complaints of snoring and with nocturia (using the bathroom at some point during the normal sleep period).  Because nocturia has such a strong pathophysiological link to sleep apnea, we are researching whether this symptom is as common as snoring in patients with breathing disorders.

The research will attempt to clarify whether snoring and nocturia are equivalent predictors of a sleep breathing disorder or whether one of these symptoms has advantages over the other when a clinical evaluation can only rely on self-report.  Such information helps us know who needs a sleep study and who does not.
