AB  - OBJECTIVE: The aim of this study is to reveal factors associated with both dozing 
      off at the wheel and motor vehicle accidents (MVAs) with sleep apnea syndrome 
      (SAS) as well as other descriptive variables for driving set as independent 
      factors. METHODS: We conducted an anonymous questionnaire survey on drivers who 
      visited the Tokyo Metropolitan Driver and Vehicle Licensing Center in order to 
      renew their driver's license from September 25 to 29, 2006. The survey requested 
      information regarding self reported experience of dozing off at the wheel, MVAs, 
      usual mileage, length of license holding period, and the participants' awareness 
      of SAS. We obtained data from 3,236 drivers (response rate: 61.8%). RESULTS: The 
      rates for previous experience of feeling sleepiness at the wheel, that of dozing 
      off at the wheel, and that of near-miss or actual MVA due to dozing off at the 
      wheel among the participants were 40.4%, 20.3%, and 10.4% respectively. 
      Multivariate logistic regression analysis revealed that dozing off at the wheel 
      was significantly associated with male gender, long-term holding of a driver's 
      license (> or = 3, < 10 years: OR = 1.58, 95% CI: 1.04-2.42, > or = 10, < 20 
      years: OR = 2.23, 95% CI: 1.47-3.38, > or = 20,< 30 years: OR = 1.89, 95% CI: 
      1.23-2.90 > or = 30 years: OR = 1.85, 95%CI: 1.18-2.89), higher usual mileage (> 
      or = 30 km per a week: OR = 1.35, 95% CI: 1.06-1.73), appearance of sleepiness 
      shortly after starting driving (< 2 hrs: OR = 1.99, 95% CI: 1.60-2.47), either 
      having awareness or a diagnosis of SAS. As to experience of near-miss or actual 
      MVA due to dozing off at the wheel, factors including male gender, long-term 
      holding period of driver's license (> or = 3, < 10 years: OR = 2.02, 95% CI: 
      1.15-3.55, > or = 10, < 20 years: OR = 2.10, 95% CI: 1.19-3.70), appearance of 
      sleepiness shortly after starting driving (< 2 hrs: OR = 1.70, 95% CI: 
      1.30-2.24), either having awareness or diagnosis of SAS were significantly 
      associated. CONCLUSION: Not only habituation effects and fatigue due to long 
      driving but also SAS have a significant impact on the occurrence of sleepiness 
      related MVAs. Moreover, early diagnosis and treatment of SAS is necessary so that 
      we can avoid dozing off at the wheel, resulting in near-miss or actual MVA.
