O artigo descreve a situação dos acidentes de trânsito no Brasil, desde a implementação do Código de Trânsito Brasileiro de 1998 até o ano de 2010. Foi realizada análise dos principais trabalhos científicos e publicações não acadêmicas nacionais. A revisão de literatura incluiu periódicos indexados, não indexados, relatórios técnicos, busca específica por autores, referências bibliográficas de artigos e contato com pesquisadores. Os principais problemas do trânsito brasileiro identificados foram aumento do número absoluto de mortos e das taxas de mortalidade, ampliação da frota de motocicletas e o uso de álcool. Foram identificados autores influentes e ilhas de produção de conhecimento nas áreas pesquisadas. Os autores apresentam algumas possíveis soluções e sugerem que o poder público não tem assumido a responsabilidade que lhe cabe no controle e redução dos acidentes de trânsito.
Effective interventions for the promotion of physical activity are urgently required in order to overcome the decline in physical activity levels in this population, particularly among the poor.
A population-based cross-sectional study was conducted in Pelotas, southern Brazil, focusing on the determinants and patterns of bicycle use as a mode of commuting by workers. Accidents during commuting and use of safety equipment were also studied. The sample included 1,705 workers (> 15 years of age) living in the urban area of Pelotas and using various modes of transportation during commuting. Crude and adjusted analyses were performed using Poisson regression, taking the design effect into account. Prevalence of bicycle use was 17.2% (95%CI: 15.4%-19.0%). Male workers and those with low schooling and low income presented higher prevalence. Less than 1.0% of the bicycles featured the safety equipment required by the Brazilian Traffic Code, and 15.0% did not even have brakes. Nearly 6.0% of workers who commuted by bicycle had suffered accidents resulting in injuries during the previous 12 months. The authors conclude that bicycling workers are a priority for interventions aimed at reducing traffic accidents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
