Outline of Final Research Achievements

The objectives of this study were: 1) to evaluate the sleep status of male workers with metabolic syndrome, including the presence or absence of SAS, using a sleep evaluation device, etc., and to clarify the relationship with labor productivity, 2) to clarify whether improvement of metabolic syndrome improves SAS, and 3) to clarify whether improvement of SAS and pre-SAS state leads to "improvement of labor productivity." However, the number of subjects was far short of the planned number. Therefore, a survey of the actual situation of SAS was conducted at another manufacturing company. Of the 72 participants, 67 were analyzed. No relationship was found between the presence or absence of SAS and labor productivity, but a relationship between BMI and SAS was suggested.

Academic Significance and Societal Importance of the Research Achievements

特定保健指導実施対象者であった8名はBMI，血圧が高かったが，睡眠評価装置を用いて特定保健指導することで，SASの有無やSASの重症度を簡易的に把握することができ，特定保健指導実施6か月後にはBMIの改善，血圧の改善に寄与できたのではないかと考えられる。
また、SASのスクリーニング調査では、BMI，血圧，RDI,AHI,ODI,酸素飽和度は関連があることが示唆された。したがって、BMI高値者はSASと関連があり、SAS有病者の早期発見・早期治療により、SASの改善が期待できると考えられる。
