Mobilidade, acidentes de trânsito e fatores associados entre estudantes universitários da Guatemala

El objetivo fue identificar y cuantificar la asociación entre la intensidad de exposición (km/año recorridos), la accidentalidad y sus factores asociados en universitarios de Guatemala. Se realizó un estudio trasversal durante el curso 2010-2011, sobre una muestra de 1.016 conductores, quienes cumplimentaron un cuestionario autoadministrado que valoraba: patrones de movilidad, uso de dispositivos de seguridad, estilos de conducción y accidentalidad. Se obtuvieron asociaciones positivas entre la intensidad de exposición y la mayor implicación en circunstancias de riesgo al volante (coeficiente de regresión ajustado de 3,25, IC95%: 2,23-4,27, para las mayores exposiciones). Tanto una mayor implicación en tales circunstancias, como una mayor edad, fueron las variables más fuertemente asociadas con la mayor accidentalidad. Pese a que la intensidad de exposición se asocia positivamente con una mayor accidentalidad, se constató que la mayor parte de dicha asociación está mediada por una mayor implicación en circunstancias de riesgo al volante.The aim of this study was to identify and quantify the association between the amount of driving (km/year), traffic accidents, and other factors among university students in Guatemala. A cross-sectional study was performed during the 2010-2011 school year in a sample of 1,016 drivers who completed a self-administered questionnaire that assessed mobility patterns, use of safety accessories, driving style, and automobile crashes. The results showed a positive association between amount of driving and greater involvement in risky driving (adjusted regression coefficient 3.25, 95%CI: 2.23-4.27, for the highest level of exposure). More frequent involvement in risky driving and older age showed the strongest associations with traffic accidents. Although the amount of driving was positively associated with a higher accident rate, most of this association was found to be mediated by involvement in risky driving practices.O objetivo foi identificar e quantificar a associação entre a intensidade de exposição (km/anos percorridos), a acidentalidade e os seus fatores em universitários da Guatemala. Realizou-se um estudo transversal durante o curso 2010-2011 sobre uma amostra de 1.016 condutores de veículos, que responderam a um questionário autoadministrado que valorizava: padrões de mobilidade, uso de dispositivos de segurança, maneira de condução e acidentalidade. Obtiveram-se associações positivas entre intensidade de exposição e maior implicância em circunstâncias de risco ao conduzir (coeficiente de regressão ajustado a 3,25; IC95%: 2,23-4,27, para as maiores exposições). Tanto a maior implicância em ditas circunstâncias como uma maioridade foram as variáveis mais fortemente associadas com a maior acidentalidade. Apesar de a intensidade de exposição ser associada positivamente com uma maior acidentalidade, estabelecemos que a maior parte da dita associação está mediada pela maior implicância em circunstâncias de risco ao conduzir

Does the Familiarity of Road Regulation Contribute to Driving Violation? A Simulated Study on Familiar and Unfamiliar Road Intersections among Young Chinese Drivers

Road accidents represent the primary cause of death among young drivers. To understand the emerging issue of young drivers’ involvement in traffic accidents abroad, risk-taking behaviors were investigated in familiar and unfamiliar driving situations. Twenty-two young Chinese drivers completed a road regulation test followed by a simulated test drive. The number of traffic violations and accidents in familiar and unfamiliar driving intersections were correlated to road regulation knowledge, risk perception scores and to self-assessment of driving skills. Significant number of mistakes was found in risk-taking situations, regardless of the familiarity of the situation, especially for drivers that presented high ratings of self-assessed driving skills. Results show that risk-taking behaviors while driving in unfamiliar conditions are mediated by psychological factors, like self-assessment of being a good driver, more than the actual knowledge of road regulation rules. Implications for international driving can be considered for future research development
