[The prevalence of sleep-disordered breathing among commercial drivers and analysis of predictive factors based on health examinations].

Sleep-disordered breathing (SDB) is associated with a range of manifestations of cardiovascular disease such as stroke, ischemic heart disease and heart failure, and it is known to cause excessive daytime somnolence and be associated with traffic accidents. Therefore, it is important to detect SDB in the early stages. We investigated the prevalence of SDB using a portable monitoring system in 81 commercial drivers. We then analyzed predictive factors for SDB using their health examination records of the same fiscal year. The prevalence of moderate to severe levels of SDB reached 28.3% in all subjects. Multivariate analysis showed that the predictive factors which significantly correlated with SDB were : presence of glucose metabolism disorders (odds ratio [OR] 6.745), weight gain greater than 10 kg from age 20 (OR 5.374), and aging (OR 1.136). These results suggest that health examination records could help detect a high-risk group of SDB, which is important because its early diagnosis could prevent commercial driver traffic accidents.
