0473 THE PREVALENCE OF SLEEP DISORDERED BREATHING IN THE ACUTE PSYCHIATRIC SETTING. (28th April 2017) - Talih, F
Abstract: Introduction: Recent evidence shows a bi-directional relationship between sleep and psychiatric disorders. This study evaluates the prevalence of obstructive sleep apnea and excessive daytime sleepiness in hospitalized psychiatric patients. Factors that correlate with obstructive sleep apnea and excessive daytime sleepiness in this sample are examined. Methods: Validated questionnaires evaluating obstructive sleep apnea and excessive daytime sleepiness were administered to 152 participants after informed consent was secured. Additional data collected included general demographics, psychiatric diagnoses, and questionnaires evaluating depression and anxiety symptoms. Statistical analyses were performed to determine the prevalence of obstructive sleep apnea and excessive daytime sleepiness, as well as their respective correlates with patient profiles. Results: Our results showed that 39.5% of participants were found to have a high likelihood of sleep apnea and 9.9% of the participants were found to have an abnormal range of daytime sleepiness. Sleep apnea correlated with body mass index (r= 0.2977, p< 0.05), age (r=0.203, p=0.05) and depression severity (r= 0.224, p<0.05). Higher body mass index was associated with a higher likelihood of sleep apnea ( χ 2 = 15.05, p<0.05). Severity of depressive symptoms was also associated with a higher likelihood of sleep apnea ( χ 2 = 8.10, p<0.05). Conclusion: Research has shown that an association between psychiatric disorders and sleep disordered breathing such as sleep apnea does exist. The biological and molecular nature behind the relationship of both disorders is multifactorial and complex but sleep apnea must be recognized in the psychiatric setting and treated accordingly.
