0394 EFFECT OF BACKGROUND NOISE ON SLEEP QUALITY

Abstract

with a stable sleep efficiency (71.3% to 72.3% compared to 75.3% to 89.0%) and a higher overall incidence of sleep apnea (80% vs. 71.5%). Conclusion: Obstructive sleep apnea is extremely common among patients presenting for CBTI, many of whom take sleeping pills that may mask the symptoms. Though CBTI may be effective, treatment failure is associated with an even higher incidence of sleep apnea. Resolution of insomnia may depend on identification and treatment of comorbid sleep apnea, which could have further impacts on long-term health.
