Background: This study investigated the influence of age, gender and geographical region on the incidence of four types of injuries among pedestrians, cyclists, motorcyclists and motor vehicle drivers in Iran. The geographical correlation between the different provinces of the country was also examined.
Objectives: The present study aimed to investigate 4 common type of road traffic injuries by provinces in Iran.
Methods: The data was taken from the Global Burden of Disease (GBD) study. The data were analyzed in terms of age group, gender and type of injury in different provinces, and the effect of geographical region on the incidence of RTIs were investigated through a multilevel analysis. Provinces were included in the model as random intercepts, and Moran's I test was used to examine geographic correlation and identify hot spots and cold spots. A significance level of 5% was used for all tests.
Results: Elderly people were the main victims of pedestrian accidents, and young people were most frequently injured in cycling accidents. On the other hand, adults were the most frequently injured age group in motor vehicle accidents. Men were injured more often than women in all four types of injury. Although the injuries were not related to the province where the accident occurred, the geographical distribution of injuries caused by cyclists showed a geographical correlation, with Sistan and Baluchistan (southeast) and Tehran (the capital) being the areas with the highest and lowest risk of these types of injuries, respectively.
Conclusion: According to the results of this study, the causes of different types of road traffic injuries are very different for different age groups, genders and geographical areas. Therefore, different plans should be developed for each type of injury in order to prevent road traffic accidents.
