The 10-year Risk of Verified Motor Vehicle Crashes in Relation to Physiologic Sleepiness

摘要: STUDY OBJECTIVES: The purpose of this study was to determine the risk DMV documented crashes as a function physiological sleepiness in population-based sample. DESIGN: 24-hour laboratory assessment (nocturnal polysomnogram and daytime MSLT) 10-year crash rate based on obtained accident records. PARTICIPANTS: 618 individuals (mean age = 41.6 +/- 12.8; 48.5% male) were recruited from general population southeastern Michigan using random-digit dialing techniques. RESULTS: Subjects divided into 3 groups their average MSLT latency (in minutes) follows: excessively sleepy, 0.0 10 (n 345). Main outcome measures data accidents 1995-2005. Rates for all were: sleepy 59.4%, moderately 52.5%, alert 47.3%. Excessively subjects at significantly greater an over period compared subjects. A similar relation observed when we limited database those victims with severe injury (excessively 4.3%, 0.5%, 0.6%; P 0.028). When victim only occupant car, lowest group (highest sleepiness) had greatest 52.2%, 42.2%, 37.4%; 0.022). INTERVENTIONS: N/A. CONCLUSIONS: These demonstrate that MSLT, measure sleepiness, is predictive increased automotive population. Language: en
