OBJECTIVETo explore the risk factors of road traffic injury (RTI), and to provide evidence for stretagy development on the prevention and control of RTI.

METHODSCase-crossover study was used. 402 drivers were face to face interviewed by specially designed questionnaire including the items as drinking alcohol before driving, onset anger scale (OAS), anxiety/irritation, Stanford sleepiness scale (SSS), vehicle breakdown, carelessness, violating the rules on right of way and traffic signs when driving. Tables related to case-control study on 1:1 matching was used for single factor analysis, and conditional logistic regression was used for multifactor analysis.

RESULTSThe risk factors that were associated with RTI including high OAS (OAS = 5-7, OR = 114.88, 95% CI:4.29-3074.86), violating the rules on right of way (OR = 46.96, 95% CI:12.74-173.11), violating traffic signs when driving(OR = 24.57, 95% CI: 8.69-69.45), carelessness (OR = 14. 54,95% CI: 6.85-30.86), unsafe distance between vehicles( OR = 14.30,95% CI: 3.68-55.60), wrong judgement (OR = 14.67,95% CI:4.88-44.10), vehicle breakdown (OR = 8.57, 95% CI: 1.38- 53.27) and improper measure ( OR = 8.46, 95% CI: 2.46-29.14) etc.

CONCLUSIONImproper driving behaviors, abnormal psychological status and driving skills of drivers were related to RTI, suggesting that it was necessary to carry out continous traffic security education to the drivers.
