OBJECTIVE: We aimed to investigate sleepiness, sleep hygiene, sleep disorders,
and driving risk among highway drivers.
METHODS: We collected data using cross-sectional surveys, including the Epworth
Sleepiness Scale (ESS) questionnaire, Basic Nordic Sleep Questionnaire (BNSQ),
and a travel questionnaire; we also obtained sleep data from the past 24 h and
information on usual sleep schedules. Police officers invited automobile drivers
to participate.
RESULTS: There were 3051 drivers (mean age, 46±13 y; 75% men) who completed the
survey (80% participation rate). Eighty-seven (2.9%) drivers reported near-miss
sleepy accidents (NMSA) during the trip; 8.5% of NMSA occurred during the past
year and 2.3% reported sleepiness-related accidents occurring in the past year.
Mean driving time was 181±109 min and mean sleep duration in the past 24 h was
480±104 min; mean sleep duration during workweeks was 468±74 min. Significant
risk factors for NMSA during the trip were NMSA in the past year, nonrestorative
sleep and snoring in the past 3 months, and sleepiness during the interview.
Neither sleep time in the past 24 h nor acute sleep debt (sleep time difference
between workweeks and the past 24 h) correlated with the occurrence of near
misses.
CONCLUSIONS: Unlike previous studies, acute sleep loss no longer explains
sleepiness at the wheel. Sleep-related breathing disorders or nonrestorative
sleep help to explain NMSA more adequately than acute sleep loss.
