由于人们认为在驾驶时使用移动电话可能导致碰撞，一些国家已经限制在机动车辆中使用移动电话，而其他国家正在考虑这样的规定。我们使用了流行病学的方法，病例交叉设计，研究是否使用手机，而驾驶增加机动车碰撞的风险。方法我们研究了699名司机谁有手机，谁参与了机动车碰撞造成重大财产损失，但没有人身伤害。通过使用详细的账单记录，分析了每个人在碰撞当天和前一周的手机通话情况。结果在14个月的研究期间，共拨打了26,798次手机通话。使用移动电话时发生碰撞的风险是不使用移动电话时的四倍（相对风险为4.3; 95%置信区间为3.0至6.5）。对于年龄和驾驶经验等个人特征不同的驾驶员，相对风险相似;接近碰撞时间的电话尤其危险（相对风险，碰撞后5分钟内拨打的电话为4.8，而碰撞前15分钟以上拨打的电话为1.3; P
Background Because of a belief that the use of cellular telephones while driving may cause collisions, several countries have restricted their use in motor vehicles, and others are considering such regulations. We used an epidemiologic method, the case-crossover design, to study whether using a cellular telephone while driving increases the risk of a motor vehicle collision.Methods We studied 699 drivers who had cellular telephones and who were involved in motor vehicle collisions resulting in substantial property damage but no personal injury. Each person's cellular-telephone calls on the day of the collision and during the previous week were analyzed through the use of detailed billing records.Results A total of 26,798 cellular-telephone calls were made during the 14-month study period. The risk of a collision when using a cellular telephone was four times higher than the risk when a cellular telephone was not being used (relative risk, 4.3; 95 percent confidence interval, 3.0 to 6.5). The relative risk was similar for drivers who differed in personal characteristics such as age and driving experience; calls close to the time of the collision were particularly hazardous (relative risk, 4.8 for calls placed within 5 minutes of the collision, as compared with 1.3 for calls placed more than 15 minutes before the collision; P
