| Outline of Final Research Achievements |
To elucidate effects of snoring on health consequences, we investigated the relationship between snoring sound intensity and daytime sleepiness according to age groups. Method: 1274 patients suspected of sleep apnea underwent diagnostic polysomnography. Subjective daytime sleepiness was assessed using the Epworth sleepiness scale. Snoring intensity was assessed using the highest one percentile ambient sound pressure level (L1) attained while asleep during polysomnography. Relationship between L1 and ESS was examined using multiple regression analysis. In addition, study subjects were classified into 3 groups(younger/middle/middle and older groups) by tertiles of age. Similar analyses were performed in each group. Result: Multiple regression analysis showed that L1 was independently related to ESS in the whole subjects and the middle and older group, but not in the younger group and middle and older group. Conclusion: Snoring can lead to daytime sleepiness, which can varied by age.

| Academic Significance and Societal Importance of the Research Achievements |
イビキは睡眠時無呼吸症候群の主要な症状の一つであるが、イビキによる本人あるいはベッドパートナーの健康障害につながる可能性がある。さらに、イビキはその有病率の高さから公衆衛生学上非常に重要な問題であるといえる。今回の研究の成果は、イビキによる健康障害のエビデンス構築につながるものであり、イビキの病態生理学的影響に重要な示唆を与えるものである。
