Abstract

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 24h and information on usual sleep schedules. Police officers invited automobile drivers to participate. RESULTS: There were 3051 drivers (mean age, 46±13y; 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±109min and mean sleep duration in the past 24h was 480±104min; mean sleep duration during workweeks was 468±74min. Significant risk factors for NMSA during the trip were NMSA in the past year, nonrestorative sleep and snoring in the past 3months, and sleepiness during the interview. Neither sleep time in the past 24h nor acute sleep debt (sleep time difference between workweeks and the past 24h) 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.
