title: Incidence of different health factors and their influence on traffic accidents in the province of Madrid, Spain.
abstract: Most traffic accidents occur as a result of human dependent risk factors. The approach in this study focuses especially on health factors, which could have direct influence on these accidents.
  
  
  METHODS
  A sample of 5430 and 2857 clinical histories were selected systematically from the total cases attended by the Emergency Service of the Community of Madrid (SUMMA 112) in 2006 and 2007. The cases of traffic accidents were studied. Statistical analyses of the correlation of the casualty accidents rate, mainly drivers' involved ones and the incidence of major risk factors was made.
  
  
  RESULTS
  Traffic accidents occur more frequently among male drivers aged between 15 and 44. When males and females are considered, the rate of traffic accidents was higher for the age group 25-34 in 2006 and for the age group 15-24 in 2007. Coming off the road is the most frequent type of accident: 24.6% and 27.8%, respectively. During weekends, the rate of accidents represents approximately half that produced during weekdays. Fatigue or insufficient sleep was admitted in 3.2% in 2006 of the total of casualty accident victims. Among drivers' involved accidents, asthma and high blood pressure were each noted in 6.6% in 2006, epilepsy and depression were each detected in 2.8% in 2007. Abuse of alcohol and cocaine were noted in 10.6% and 4% of drivers' involved accidents in 2006. In 2007, drivers' abuse of alcohol and drugs was detected in 5.6% and 3.7%, respectively.
  
  
  CONCLUSIONS
  Traffic accidents, especially coming off the road type, are more frequent among young adults and during weekends. Also, there is risky behaviour involved, such as driving under the influence of alcohol, abuse of drugs or having insufficient sleep or certain diseases.
