Abstract:
Objective To explore the related risk factors of injuries caused by non-motor vehicle crashes in Hefei,Anhui Province. Methods From June 2009 to June 2011,the wounded from nonmotor vehicle crashes in Hefei were admitted to our hospital.The data of the wounded were collected to perform hypothesis test to screen out the related risk factors,which were then analyzed with multiple-factor non-conditional Logistic regression analysis. Results A total of 205 cases who were wounded in the non-motor vehicle crashes were admitted to our hospital from June 2009 to June 2011.Among all the cases,146 cases were wounded in electric bicycle crashes and 59 cases in bicycle crashes.There were 147cases (71.7％) of mild to moderate injuries ( ISS ≤ 15 ),and 58 cases (28.3％) of severe injuries (ISS ＞ 15 ) including six deaths (2.9％).Single factor of different categories of the hypothesis test suggested that age,category,driving behavior,crash model,impact type,vehicle type were all related with the severity of injuries caused by non-motor vehicle crashes in Hefei.The multiple-factor non-conditional Logistic regression analysis showed four risk factors for the injury severity in non-motor vehicle crashes in Hefei,ie,vehicle type,crash model,violations of rules and regulations as well as age,according to the degree of correlation.Conclusion With the study of non-motor vehicle crashes in Hefei,primary identification of the risk factors for the traffic injuries is obtained,which provides scientific basis for the decrease of casualty and establishment of intervention measures.
