Objective: To determine the causal relationship between aging and nighttime driving and the odds of injuryamong elderly drivers.Methods: In this cross-sectional study, 5460 car accidents were investigated from 2015 to 2016. The data wereextracted from the Iranian Integrated Road Traffic Injury Registry System. Pedestrian accidents, motorcyclecrashes, and fatalities were excluded from the study. To account for major confounders, Bayesian-LASSO, andtreatment-effect cutting-edge approaches were used.Results: Overall, 801 injuries (14.67%) were evaluated. The results of the univariable analysis indicated thataging and nighttime had adverse effects on the odds of road traffic injuries (RTIs), even after adjusting forthe effect of other variables, these effects remained statistically significant. According to a newly developedapproach, the overall effects of aging and nighttime were significantly and directly correlated with the odds ofbeing injured for older adults (both p<0.001). Our findings indicated that drivers over 75 years old experienced23% higher injury odds (OR=1.23, 95% CI:1.11 to 1.39; p<0.001), while driving at night increased the odds by1.78 times (OR=1.78, 95% CI:1.51 to 1.83; p<0.001).Conclusion: Aging and nighttime driving are significant risk factors for RTIs among elderly drivers. Thishighlights the importance of implementing targeted interventions to enhance road safety for this vulnerablepopulation. Furthermore, the use of advanced Bayesian-LASSO and treatment-effect statistical methodshighlights the importance of utilizing sophisticated methodologies in epidemiological research to effectivelycapture and adjust for potential confounding factors.

Objective: To assess psychometric properties of the European Quality of Life 5-Dimension 3-Level Version(EQ-5D-3L) commonly used tool for measuring road traffic injury (RTI) patients’ quality of life.Methods: The psychometric study assessed the reliability and applicability of EQ-5D-3L through phonesurveys, based on a national cohort platform. Data of 150 RTI patients recruited from the cohort study wereincluded as 50 patients per each follow-up phase (one, six, and twelve months after discharge). A 12- day-timespan was between test and retest. We measured psychometric properties (internal consistency reliability andstability reliability) and agreement using Kappa coefficients and percentages of agreement and Bland-Altmanmethod. Data were analysed using software STATA statistical package.Results: The majority of patients were men (80%) with mean age (SD) of 41(14.7%), employed (78%) andeducated (86%). The Persian version represented high internal consistency reliability at total level (Cronbach’sα=0.81) and moderate to good reliability at phase levels (0.62-0.87). The stability reliability was excellent attotal (ICC=0.98, 95% CI: 0.97, 0.98) and phase levels (0.97-0.98. The kappa agreement coefficients were valuedmoderate to perfect (0.6-0.8, p>0.0001). The Bland-altman plot illustrated high agreement between test andretest scores. No floor and ceiling effects were found.Conclusion: The study revealed that EQ-5D-3L was highly reliable and responsive to be applied through phoneinterviews at three different times post injury and discharge, as no previous study considered its psychometricproperties at various phone follow-ups after RTIs.

Objective: To investigate epidemiological aspects of injuries among Iranian children under 7 years of age using obtained data from a national registry.Methods: Injury data were derived from a national-based injury supervision system during 2000–2002. This registry involved all of home-related injuries for children less than 7 years of age that treated in health or emergency centers. The study population included 25% of Iranian people. The descriptive statistical methods were used for representing the distribution of the variables like age, sex, injury mechanisms, types of injuries, etc. Data were presented as mean ± SD and proportions as appropriate.Results: Of the total 307,064 domestic injuries registered during 2000–2002, 77,500 cases (25.2%) were children. 70% of these children (54581 cases) were in age group of 1-5 years.The large fraction (58.8%) of injuries among children under 7 years of age went back to burn injuries. Cuts and lacerations were at the second level with 17.4%. 51% of injuries had contact with hot liquids. Of all children under 7 years of age injuries, 282 died, 86 were disabled, while the rest improved or being under treatment when recording data.Conclusion: Injuries, particularly burns (especially those who had contact with hot liquids that led into scald), are major public health problem that children under 7 years of age encounter. Therefore, it seems necessary to provide adequate plans to promote children under 7 years of age safety issues.
