Materials & Methods: A cross-sectional study was conducted on 177 injured pedestrians that injured by motor vehicles in the RTIs and were hospitalized inShohadahospital during May 2013 to April 2014. The investigated variables: demographic and environmental characteristic of injured pedestrian. Both descriptive and analytical statistics were used. 1- Descriptive statistics: The results were reported with descriptive indices for continuous variables such as mean (Standard Deviation) or median and Inter Quartile Range (IQR) according to the distribution, and for categorical variables such as frequency (percent). 2- The case-control study had hospital-based design. 177 participate that were injured by the vehicles in the RTIs and hospitalized in the Shohada hospital was compared with 177 controls without any of injuries in the RTIs from Imam Reza hospital were selected. The analysis between two groups for the effects of stressful life events, and adult ADHD was done using univariate and multivariate methods. Results: The mean age of victims was 40.05 (14.26) years old. Men were 86.4% of all victims. In terms of education graduate, 27.7% of the victims were elementary and 22.6% illiterate. 27.8% of the victims were self-employed and 16.5% were workers.

The higher proportions of injuries were occurred in sunny days with 66.1% and 70.1% during day time. Also, pedestrian status during accidents, 46.9% of victims was injured in moving and admissible line. There was significant association between type of job and site of the body injury (P<0.05). Multivariate logistic regression showed that variables associated with pedestrian injuries in the RTIs were stressful life events were comprised job conflicts, education concerns, daily life, health concerns, mean walking at day, economicD Abstract status, and education levels.Multivariate logistic regression showed that variables associated with pedestrian injuries in the RTIs were subscale D index (OR=1.06, 95% CI: 1.01-1.12); economic status (OR=0.96, 95% CI: 0.93-0.99); elementary education (OR=0.44, 95% CI: 0.25-0.79), and bachelor and master (OR=0.16, 95% CI: 0.05-0.52). Conclusion: The results of the present study showed that prevention and management of pedestrian injuries needs appropriate actions from both individuals and the environment intervention toward psychological factors and decrease socioeconomic difference may be affective in the diminish pedestrian injuries in the RTIs.
