How Socioeconomic Status Influences Road Traffic Injuries and Home Injuries in Rome

Road traffic injuries (RTI) and home injuries (HI) are a relevant public health problem, especially among people living in deprived areas. The objective of this study was to explore the relationship between morbidity, hospitalisation, mortality from RTI and HI, and socioeconomic status (SES) of the area of residence. RTI and HI surveillance based on the Emergency Information System, the Hospital Information System and the Mortality Registry of Lazio region are the three sources of this study to create a unique surveillance system. For each subject, the SES index (5 levels) of its census tract of residence was obtained. The study population included emergency department admissions (year 2005) of residents in Rome, Italy. Incidence Rate Ratios (IRRs) have been estimated using Poisson Regression. The rates of RTI and HI emergency department visits were higher among the most deprived level of SES (IRR=1.27, 95% CI: 1.241.30; IRR=1.33, 95% CI: 1.291.37, respectively) compared to the most privileged ones; a similar result was found for hospitalisation (IRR=1.19, 95% CI: 1.081.32; IRR=1.11, 95% CI: 1.011.22). A strong relation was found between RTI mortality rates and poor level of SES. The study concluded that RTI and HI incidence were associated to sociodemographic factors.
