ObjectiveTo assess the reach of three different types of road safety interventions (social marketing, education and law enforcement) implemented as part of the Iniciativa Mexicana de Seguridad Vial y Prevención de Lesiones en el Tránsito (Mexican Initiative for Road Safety and the Prevention of Road Traffic Injuries) among youth in two Mexican cities (Guadalajara-Zapopan, Jalisco and León, Guanajuato), and to examine students' self-reported attitude change after being exposed to these interventions.MethodsA cross-sectional design was utilized to evaluate the reach of the city-wide interventions among a random sample of public and private high school and college students from October to December 2011. A total of 5,114 students completed a self-administered questionnaire.ResultsIn both cities, students reported a greater exposure to social marketing (73% in Guadalajara-Zapopan and 64% in León) as compared to educational interventions (29.3% in León and 21.6% in Guadalajara-Zapopan) and law enforcement activities (~12% in both). Among respondents, self-reported attitude change was higher after being exposed to educational interventions than law enforcement. Social marketing yielded the lowest prevalence of self-reported attitude change.DiscussionOur results show a potential moderate impact, measured as self-reported attitude change, resulting from the three intervention approaches under study. Future studies should address the intensity of exposure as well as the translation of attitude change into safer behaviors. Information generated by this study could be useful for local authorities in the intervention areas to inform their activities.Copyright © 2013 Elsevier Ltd. All rights reserved.
