MIGRAINE - A RISK FACTOR FOR MOTOR-VEHICLE DRIVER INJURY

To test the hypothesis that migraine is associated with motor vehicle driver injury, data collected from 10,529 individuals on personal hist ory of migraine and motor vehicle injury were analysed cross-sectional ly. In multiple logistic regression analyses, the adjusted odds ratio for motor vehicle driver injury associated with migraine was 2.3 [95% confidence interval (CI) 1.9-2.7]. After excluding those who also had a history of head injury, the odds ratio was 1.5 (95% CI: 1.2-2.0). Th ese results suggest that migraine may be associated with a 50% increas e in the risk of motor vehicle driver injury and that in this populati on may account for as many as one in every 20 motor vehicle driver inj uries. These findings require confirmation in prospective studies of m otor vehicle driver injuries. (C) 1997 Elsevier Science Ltd.
