Traffic accidents among drivers: incidence and differences between motorcyclists and car drivers in population-based study.

Objectives: To estimate the incidence of traffic accidents among land vehicle drivers and to verify differences between motorcyclist and car driver accident victims.

Methods: A household survey was conducted in Jequié city, Bahia, Brazil, in 2013, with 1,406 drivers who were selected by cluster sampling strategy. Estimates of the cumulative incidence of traffic accidents were weighted by the sample design and, to compare groups of drivers, incidence rates (IR) and 95% confidence intervals were calculated with Poisson Regression.
