Abstract

Nearly 1.3 million people die every day in traffic accidents (TA) worldwide, and 20â�?�?50 million people are injured. In 2010, the Brazilian public hospitals registered over 146 thousand admissions due to TA. S�?£o Paulo is the most populous city in the country, with nearly 11.8 million inhabitants and a fleet of more than 7.5 million vehicles. This study aims to describe the profile of hospital admissions due to TA in S�?£o Paulo and its time trend over the period 2000-2014. Hospital admissions data on TA was obtained from the Health State Secretary. Each victim was classified in one of the four groups according to the type of transport, based on ICD 10th revision: all, pedestrian, motorcyclist, vehicle occupant. Age groups were defined as 0-14, 15- 19, 20-39, 40-59, 60 years and over. Statistical analysis was performed using Negative Binomial regression models. Around 80% of admissions were of males. Running over pedestrians were responsible for the higher morbidity rates among man until 2003. Since 2004, motorcycle accidents are the main cause; rates (number of admissions per 100.000 inhabitants) have greatly increased during the period (from 14,8 to 42,5 p<0,05). Age groups most susceptible to this type of accident were 15-19 and 20-39 years. Those aged 0-14, 40-59 and 60 years and over were admitted mainly as victim of trampling; the rates showed little fluctuation over the period (from 24,8 to 22,3 p>0,05). The rates for vehicle occupants did not change much during the period (from 7,6 to 7,4, p>0,05).
