Investigating of Effective Factors on Pedestrian Injuries in Road Traffic Injuries: A case control study in Tabriz-Iran
Abstract
Background & Aims: The aims of this study was describe some epidemiological
characteristics of injuries of pedestrian, effect stressful life events interval one year past,
andadult ADHD as predicting factors oninjuries of pedestrian in the Shohadaand Imam Reza
Hospital, East Azerbaijan province.
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. Economic status
of injured pedestrians was 13.29 (32.46). Lower extremity were comprised 43.5% of all
injuries, and 31.64% of victims had been injuries to more than two organs. As well as,
59.32% of injuries were occurred in two-sided streets, and 37.3% of injuries were happened
during 6-12 p.m. 80.8% of the injuries happened during working days accordance with local
calendar. 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.
