Abstract
Objective: In recent years various studies have been conducted regarding the effects of CRS on the patient’s quality of life (QOL). There have, however, been few reports of its effects on the quality of sleep. Accordingly, we examined which factors are involved in sleep problems associated with CRS.
Method: Multicenter prospective study. We analyzed 685 consecutive CRS patients between April 2007 and March 2008. All patients completed a QOL questionnaire and background parameters. The patients who had sleep problems (SP group) were compared with other patients in regard to nasal symptoms and background parameters.
Results: A total of 148 patients (21.6%) had sleep problems. The scores for each of the nasal symptoms were significantly higher in the SP group. In addition, the sleep score was significantly higher in the patients with a complication of allergic rhinitis and the patients with high peripheral and tissue eosinophil counts. Logistic regression analysis found that nasal congestion, cough, and ear fullness were nasal symptoms that contributed to the SP group.
Conclusion: This study indicated that, in addition to nasal symptoms, inflammatory conditions such as allergic rhinitis and eosinophilic inflammation have the potential to directly affect sleep problems. Logistic regression analysis revealed that subjective symptoms, such as nasal congestion, cough, etc, are closely related to sleep problems.
