title: Relationship between diabetes mellitus and excessive sleepiness during driving.
abstract: OBJECTIVE
  It is still unclear whether patients with diabetes feel excessive daytime sleepiness or dose/sleep during driving in patients more frequently.
  
  
  METHODS
  A population-based cross-sectional survey was conducted in a rural town. Multivariable-adjusted logistic regression models were used to explore the association between prevalent diabetes cases and excessive daytime sleepiness or dose/sleep during driving.
  
  
  RESULTS
  Of 4540 participants, a total of 470 diabetes cases were identified. Compared with those in the never doze/sleep category, multivariate-adjusted odds ratios of diabetes was 0.41 (95%CI, 0.12-1.35) in slight category of dozing or sleeping when stopped for a few minutes in traffic while driving and 2.97 (95%CI, 1.19-7.41) in the moderate to high categories of dozing or sleeping when stopped for a few minutes in traffic while driving. This association remained significant after adjusting for the presence of poor sleep quality defined by the global Pittsburgh Sleep Quality Index score equal or greater than 5.
  
  
  CONCLUSIONS
  Compared to individuals without diabetes, patients with diabetes experienced excessive daytime sleepiness or dozing/sleeping when stopped for a few minutes in traffic while driving more often independent of poor sleep quality. From the public health perspective, all patients with diabetes should be asked about a history of excessive daytime sleepiness or dozing/sleeping while driving, which is a known risk factor for future traffic accidents.
