Introduction:
Paediatric, pedestrian road traffic injuries (PPRTIs) constitute a major cause of premature death in Iran. Environmental factors play a significant role in PPRTI events. Identification of high-risk areas and quantifying environmental risk factors would be the primary step in designing policy intervention for PPRTI reduction.
Methods:
This cross-sectional retrospective study was conducted on all pedestrian accidents of children (less than 18 years of age) with motor vehicles between March 2015 and March 2019 in city of Mashhad, which is the second most populous city in Iran. The Anselin Local Moran’s I statistic and Getis-Ord Gi* were performed to measure spatial autocorrelation and hot spots of PPRTIs at the geographical grid network and administrative neighbourhood level. Furthermore, a spatial buffer analysis was used to classify the streets according to their PPRTI rate.
Results:
A total of 7,390 PPRTIs (2,364 females and 4,974 males) were found during the study period. The children's mean age was 9.7±5.1 years. Out of the total PPRTIs, 43% occurred on or at the fringes streets, 25 of which were labelled high-risk streets. A high-high (HH) cluster of PPRTI was discovered in the eastern part of the city, while, in the West there was a low-low (LL) such cluster. Additionally, in the western part of the city, older children were more likely to become injured, while in the north-eastern and south-eastern part, younger children were more often victims.
Conclusions:
Spatial analysis of PPRTIs in an urban area at three different geographical scales, including grid network, neighbourhood level and street levels, contributes reliable documentation that would help policy-makers implement and prioritize different preventive strategies such as improvement of the high-risk streets and neighbourhoods of the city for decreasing the number of PPRTIs.
