OBJECTIVE: To document the effects of sudden economic change on death rates for occupants of cars in the former German Democratic Republic (East Germany). DESIGN: Ecological time series study of East Germany in comparison with the former Federal Republic of Germany (West Germany) before and after reunification in 1990. SETTING: East and West Germany from 1985 to 1996. SUBJECTS: Populations of East and West Germany between 1985 and 1996. MAIN OUTCOME MEASURES: Death rates for occupants of cars. RESULTS: After the reunification of Germany, East Germany experienced a sudden, temporary affluence and a concomitant fourfold increase in death rates for car occupants between 1989 and 1991. Although death rates increased in all age groups, young adults (aged 18-24) were most affected. The death rate per 100 000 population for those aged 18-20 years increased 11-fold between 1989 and 1991; for those aged 21-24 years the increase was eightfold. CONCLUSION: A tragic consequence of the reunification of Germany was a dramatic increase in the death rate for car occupants. Sudden economic change and availability of cars resulted in both a rise in vehicle ownership and an increase in the number of inexperienced drivers on roads that were ill prepared for the increased traffic. The lesson learnt from Germany is that during times of economic change and modernisation, measures to prevent the predictable injury deaths that will result need to be considered.

OBJECTIVE: To evaluate the sleep hygiene and prevalence of sleep deprivation among a large sample of automobile drivers. DESIGN: From the 15th of June to the 4th of August 1996, with the help of the French highway patrol, we randomly stopped automobile drivers at the toll booths of Bordeaux and Biarritz. All subjects completed a validated questionnaire on sleep/wake habits during the year. After answering the questionnaire, subjects completed a graphic travel and sleep log of the three days preceding the interview. PARTICIPANTS: We randomly stopped 2196 automobile drivers. Ninety-one percent of the sample (mean age 43 +/- 13 years) agreed to participate in the survey. RESULTS: Fifty percent of the drivers decreased their total sleep time in the 24 hours before the interview compared with their regular self-reported sleep time. 12.5% presented a sleep debt > 180 minutes, and 2.7% presented a sleep debt > 300 minutes. Being young, commuting to work, driving long distances, starting the trip at night, being an "evening" person, being a long sleeper during the week, and sleeping in on the week-end were risk factors significantly associated with sleep debt. CONCLUSION: The results of the study highlight variables (long-distance driving, youth, sleep restriction) that are frequently associated with sleep-related accidents.
