RESUMO: Objetivo: Analisar o efeito do uso de capacete na gravidade de lesões em condutores e passageiros de motocicletas envolvidos em acidentes de trânsito. Métodos: Estudo de corte seccional sobre vítimas de acidentes de transporte terrestre envolvendo motociclistas, atendidos nos serviços de urgência e emergência e participantes do Inquérito de Vigilância de Violências e Acidentes (Viva Inquérito) 2017. Resultados: Verificou-se predomínio de indivíduos na faixa de 18 a 29 anos (46,6%), negros (75,2%) e com ensino médio (50,6%). Em 14,1% dos acidentes houve relato de uso de álcool. O uso do capacete reduziu em 76% a ocorrência de trauma cranioencefálico e em 28% a ocorrência de encaminhamento para outro hospital, internação ou óbito. Conclusão: Motociclistas jovens, negros, de baixa escolaridade e do sexo masculino apresentaram-se mais vulneráveis aos acidentes. O uso do capacete mostrou-se protetor para lesões graves.

ABSTRACT: Objective: To analyze the effect of helmet use on injury severity among motorcyclists and passengers involved in traffic accidents. Methods: Cross-sectional study of traffic accidents involving motorcyclists attended at the emergency healthcare units participating in the Violence and Accidents Survey Conducted in Sentinel Emergency Departments (Viva Survey) 2017. Results: There was a predominance of individuals aged 18 to 29 years old (46.6%), black (75.2%), with high school education (50.6%). Alcohol use was observed in 14.1% of cases. Helmet use was associated with a 76% reduction in the occurrence of head trauma and a 28% reduction in the referral, hospitalization or death. Conclusion: Young, male, black individuals and those with low education were the most frequent victims of accidents. Helmet use was protective for severe injuries.

Perfil e tendência dos fatores de risco para acidentes de trânsito em escolares nas capitais brasileiras: PeNSE 2009, 2012 e 2015 / Profile and trend of risk factors for traffic accidents in schoolchildren in Brazilian capitals: PeNSE 2009, 2012 and 2015

RESUMO: Introdução: Os acidentes de transporte terrestre (ATT) são a segunda causa de morte em escolares de 13 a 17 anos. O presente estudo visou descrever os fatores de risco para ATT em escolares da Pesquisa Nacional de Saúde do Escolar (PeNSE) de 2015 e avaliar a tendência de indicadores selecionados nas três últimas edições da PeNSE. Metodologia: Estudo descritivo sobre fatores de risco para ATT no ano de 2015, com dados da PeNSE e análise de tendência das séries temporais, com testes de regressão ajustados por idade, das edições de 2009, 2012 e 2015, nas capitais brasileiras. Resultados: Em 2015, 26,3% dos escolares do nono ano, na maioria entre 13 e 15 anos, relataram terem sido conduzidos em veículo motorizado dirigido por alguém que consumiu bebida alcoólica e 32,4% relataram terem dirigido veículo motorizado; 30,7% dos adolescentes não usaram cinto de segurança no banco de trás; e 16,8% dos escolares usuários de motocicleta não usaram capacetes. Observou-se ainda tendência de piora dos indicadores entre 2009 e 2015, referentes a dirigir veículo motorizado (1,0 pontos percentuais) e ter sido conduzido em veículo por alguém que consumiu bebida alcoólica (1,1 pontos percentuais). Discussão: A ocorrência de ATT resulta da interação entre vias, veículos e usuários, tendo forte correlação com o comportamento. Conclusões: Os resultados apontam a necessidade de investir em medidas educativas, associadas a fiscalização, a melhoria das vias, pesquisas e aprimoramento da legislação. O monitoramento dos fatores de risco em escolares contribui substancialmente para apoiar intervenções das políticas públicas intersetoriais para a redução de morbimortalidade por trânsito.

ABSTRACT: Introduction: Land transport accidents (LTA) are the second cause of death in schoolchildren aged 13 to 17 years. The study aims to describe the risk factors for LTA in schoolchildren from the National School Health Survey (PeNSE) of 2015 and to evaluate the trend of selected indicators in the last three editions of PeNSE. Methodology: A descriptive study on risk factors for LTA in 2015, with PeNSE data and time series trends analysis, with age-adjusted regression tests of the 2009, 2012 and 2015 editions, in Brazilian capitals. Results: In 2015, 26.3% of ninth grade schoolchildren, mostly between 13 and 15 years of age, reported having been in a motor vehicle driven by someone who consumed alcohol and 32.4% had driven a motor vehicle; 30.7% of adolescents did not use seat belts in the back seat; and 16.8% of schoolchildren who ride motorcycles did not wear helmets. There was also a worsening of the indicators between 2009 and 2015, regarding driving a motor vehicle (1.0 percentage points) and having been driven by vehicle for consumption of alcoholic beverages (1.1 percentage points). Discussion: The LTA occurrence results from the interaction between roads, vehicles and users, and has a strong correlation with behavior. Conclusions: The results show the need to invest in educational measures, associated with supervision, the improvement of road infrastructure, research and improvement of legislation. The monitoring of risk factors in schoolchildren substantially contributes to support intersectoral public policies interventions to reduce morbidity and mortality in traffic.

A study on human risk factors in non-fatal road traffic accidents at Nagpur.

A cross sectional study was conducted among 423 victims of road traffic accidents reporting to Indira Gandhi Medical College, Nagpur for treatment during 1999-2000. Data was collected on pre-designed proforma by interview technique. Majority of the victims were male (85.8%) and of 18-37 years (74%); 64.5% of the subjects were consuming alcohol regularly and 5.9% were drug abusers; 43.7% and 10.2% had visual and hearing impairment respectively; 43.5% were not having any driving experience and 74.4% of the victims with two wheelers were not using any helmets at the time of accidents. Findings highlight the need for sustained health education and enforcement of traffic laws.

El respeto a las normas de tránsito en la cuidad de Santa Fe, Argentina / Traffic law compliance in the city of Santa Fe, Argentina

Se realizó un estudio de campo observacional descriptivo para evaluar el cumplimiento de algunas normas de tránsito en la ciudad de Santa Fe, Argentina, y comparar los resultados con mediciones realizadas anteriormente. Para ello, entre el 2 y el 4 de enero de 2006, se verificó en 13 sitios de la ciudad el cumplimiento de las normas que obligan a los automovilistas a usar cinturón de seguridad y a llevar a los menores de 10 años en el asiento trasero, y a los motociclistas, a conducir con casco y a no transportar menores. Las observaciones abarcaron 4 173 automóviles y 1 013 motocicletas. Solo 9 por ciento de los conductores de automóviles usaban el cinturón de seguridad. En 56 por ciento de los 246 automóviles que transportaban menores, estos se hallaban en el asiento delantero. En cuanto a los motociclistas, solo 12 por ciento usaba casco y 6,7 por ciento transportaba niños. Al comparar estas observaciones con cinco registros anuales anteriores, se comprobó que en los últimos tres años disminuyeron los porcentajes de acatamiento de estas normas de tránsito. Los resultados de este estudio sugieren que la mayoría de los conductores de vehículos de la ciudad argentina de Santa Fe viola las normas de tránsito consideradas. Para lograr disminuir la elevada mortalidad por accidentes viales no basta con contar con leyes de tránsito y organizar campañas de información, sino que, además, es necesario implementar sistemas que vigilen el cumplimiento de las normas.

An observational, descriptive study was conducted to evaluate compliance with certain traffic regulations in city of Santa Fe, Argentina, and compare these with measurements taken in prior years. During January 2-4, 2006, at 13 sites across the city, compliance with the following traffic rules was measured: for car drivers: seat belt use and restricting minors to the rear seat; and for motorcycle drivers: helmet use and not carrying a minor on board. At total of 4 173 cars and 1 013 motorcycles were observed. Only 9 percent of the car drivers wore seatbelts. Of the 246 cars carrying minors, 56 percent had a minor in the front seat. Regarding the motorcycles drivers, only 12 percent wore a helmet and 6.7 percent had a child on board. When these observations were compared with those of the previous five years, findings showed that over the past three years compliance rates had decreased. The results of this study suggest that most drivers in city of Santa Fe do not obey the stated traffic laws. In order to reduce the high rate of mortality from traffic accidents, in addition to legislation and public-awareness campaigns, a system for enforcing compliance is needed.

Motorcycle helmet use and related risk behaviors among adolescents and young adults in Northern Thailand.

The objective of this study was to assess the prevalence of not wearing a helmet (unprotected) while riding a motorcycle and associated risk behaviors among adolescents and young adults in Northern Thailand. Participants were 1725 students, aged 15-21 years, from 3 vocational schools in Chiang Rai Province; 51.8% were male. Participants completed a classroom-based computer-assisted self-interview (ACASI). Of men 72.7% and of women 64.4% reported unprotected motorcycle riding 3 times or more in the past week. Logistic regression analysis showed the variables independently associated with unprotected riding to be history of ever riding after having had 3 or more alcoholic drinks (odds ratio (OR) = 2.21, 95% confidence interval (CI) = 1.76-2.21), attending technical school (OR = 2.09, 95% Cl = 1.55-2.83), living with the family (OR = 1.38, 95% CI = 1.10-1.73), and having ever had a traffic accident (OR = 1.20, 95% CI = 1.12-1.29). Being of hill tribe ethnicity (vs Thai lowlander) was associated with protected riding (OR = 0.42, 95% CI = 0.20-0.90). Adolescents and young adults in Chiang Rai are at high risk for riding a motorcycle without a helmet buckled on the head. Public education in combination with enforcement of compulsory helmet use while riding a motorcycle is recommended.
