Abstract
|
Background Drowsy driving is estimated to be a causal factor in 2-16 % of vehicular crashes. Several populations are reported to be at high risk for drowsy driving accidents, including shift workers, teenage drivers, medical residents, and pilots. Although new parents are known to have significant sleep disruption, no study has investigated vehicular accidents or near miss accidents in this population.
METHODS A preliminary cross-sectional, anonymous survey of parents who had given birth within the previous 12 months. Participants were asked about their sleep, including validated measures of sleep disruption, their driving patterns, and information about near miss traffic accidents and actual crashes.
RESULTS Overall, 72 participants were enrolled. A large proportion of participants had poor sleep including approximately 30 % with daytime sleepiness, 60 % with poor daytime function and two-thirds with poor sleep quality. The mean sleep duration was only 6.4 h. Although most participants drove <100 miles per week, 22.2 % reported at least one near miss accident and 5.6 % reported a crash. Sleep problems were more common in those with near miss accidents and actual crashes than in those without. Of note, poor sleep quality was associated with a sixfold increase in near miss accidents even after accounting for other factors.
CONCLUSION Poor sleep is common in new parents and we provide preliminary evidence that sleep disruption in this population is associated with near miss motor vehicle accidents. Drowsy driving results in thousands of unnecessary serious injuries and fatalities each year; raising public awareness that new parents are a high-risk group is important.
