Resumo
Background: In recent decades middle-income countries have experienced a rapid increase in the number of cars
and motorcycles. Increased deaths and hospitalizations due to road traffic injuries (RTI) has been observed in several
countries as a result. In this study we assessed the determinants of RTIs in Brazil by mode of transportation and
compared differences in RTI rates among macro-regions.
Methods: We used data from the National Health Survey (NHS) conducted in 2013 by the Brazilian Institute of
Geography and Statistics and the Ministry of Health. NHS is a comprehensive household survey which includes a
representative sample (N = 60,198) of individuals aged 18 years or older. The prevalence and determinants of RTI
were estimated according to different modes of transport (car/van, motorcycle, and other) and regions of the
country. Bivariate and multivariable logistic regression models were applied to assess crude and adjusted odds
ratios, respectively, and their 95 % CI for RTI determinants.
Results: The prevalence of RTI for the Southeast, South, Central-West, Northeast and North regions of Brazil was
2.4 %, 2.9 %, 4.4 %, 3.4 % and 4.8 %, respectively, pointing to important differences among regions. High percentages of
motorcyclists were observed in the Northeast and North regions. For motorcyclists, factors associated with RTIs were
being male (OR = 2.6;95 % CI:2.3;3.0), aged 18–29 (OR = 3.2; 95 % CI:2.7;3.8) and 30–39 years (OR = 2.0;95 % CI:1.7;2.5),
black (OR = 1.4;95 % CI:1.1;1.7), having elementary educational (OR = 1.5;95 % CI:1.1;1.9), reporting binge drinking behavior
(OR = 1.3;95 % CI:1.1;1.5), and living in the Central-West (OR = 2.0;95 % CI:1.6;2.5), Northeast (OR = 1.8;95 % CI:
1.5;2.1) and North (OR = 2.0;95 % CI:1.6; 2.5) regions of the country. The independent variables associated with RTI for
car/van occupants were being male (OR = 1.7;95 % CI:1.4;2.1), aged 18–29 (OR = 1.5;95 % CI:1.1;2.0) and 30–39 years
(OR = 2.5;95 % CI:1.9;3.2), reporting binge drinking behavior (OR = 2.0;95 % CI:1.6;2.5) and living in the South
region (OR = 1.6;95 % CI:1.3;2.1).
Conclusions: There were considerable regional disparities in RTI rates across Brazil’s regions. Motorcyclists
contributed to the high RTI rates in these regions as did demographic factors and behaviors such as alcohol
use. These findings can help guide interventions to reduce the burden of RTIs in Brazil.
