Background In Mexico, motorcycle use is increasingly prevalent owing to the availability and low fuel consumption of the vehicle. With the increasing number of motorcycle users, the rate of injuries and mortality due to road traffic accidents has also increased. Objective The study aimed to describe the epidemiological profile of injured motorcyclists treated in a third-level hospital, who were involved in traffic accidents in Guadalajara's Metropolitan Area and Zapotlanejo municipality. Methods We realized a logistic regression model, where we included all variables with p<=0.25, they had three or less response options became in dummy variables for facilitate the analysis and we took as confounders factors either variables that modify up to 10% the value of Odd Ratio. Results In our study, we examined 180 injured motorcyclists. The factors that increases risk of severe injury at Metropolitan Zone of Guadalajara and Zapotlanejo’s town were as follows: the motorcycle was not functioning properly prior to the incident (OR 76.89, 2.08-2839.25), the motorcyclist consider had committed any traffic infraction at the time of the event (OR 6.88, 1.30-36.26), the injured live in Metropolitan Zone of Guadalajara (OR 7.58, 1.15-50.17), driving a motorcycle when the driver did not know if the vehicle was “salvage” or not (OR 113.84, 9.13-1419.96) and as protectors factors, we found that a person drove a motorcycle with brand not Italika (OR 0.06, 0.008-0.41) and the road traffic occurred by line road or intersection “+”(OR 0.10, 0.02-0.61). Conclusion This information allowed to observe that exist elements of motorcyclist, and the motorcycle and environment that increases or reduced severity injuries in this group, most important when they did not have a health insurance.

IntroductionTraffic events are one of the five leading causes of mortality in Mexico. Pedestrians are one of the main road users involved in such incidents and have the highest mortality rate, which is regularly analysed in relation to vehicles and pedestrians, but not the built environment. The purpose of this study was to analyse the elements of the road system organisation that influences the mortality rate of pedestrians hit by motor vehicles in the Guadalajara Metropolitan Area.MethodWe designed a case and control study in which the cases were sites where a pedestrian died during 2012. The controls were sites close to where the death occurred, as well as those with road infrastructure characteristics similar to those where the events took place. We obtained the pedestrian data from the death certificates and assessed some of the environmental elements of the road sites. A logistic regression analysis was used to estimate OR; 95% CI.ResultsRoad system factors related with pedestrian mortality in close locations were: the presence of bus stops on intersections in one street or both, and road system features, such as the presence of traffic islands, vehicle flow and pedestrian flow.ConclusionsAccording to the urban network theory and multiple theory, the final elements resulted as risk factors due to a fault in connectivity between the nodes. A temporal analysis of urban features will help urban planners make decisions regarding the safety of pedestrians and other road users.

This study aimed to adapt the Work-Health Balance questionnaire (WHBq; (Gragnano, Miglioretti, Frings-Dresen, & de Boer, 2017) into Spanish and to provide evidence for its factorial structure, reliability, and validity. WHBq comprises 17 items with three scales: Work-Health Incompatibility (WHI), Health Climate (HC) and External Support (ES). It was applied to a sample of Mexican workers (n =316). Confirmatory factor analysis revealed that the three-factor model replicating the original structure provided good fit (CFI = 0.950; SRMR = 0.051; RMSEA = 0.069). The reliability of each factor and the whole questionnaire were satisfactory (α and ω higher than 0.70). The AVE was lower than 0.50 only for ES. Solutions to this problem are discussed. Concurrent and differential validity was examined with external criteria. The WHBq in its Spanish version shows good psychometric properties and theoretically consistent relationships with external variables. These findings provide support for its use as a valid and reliable tool in Mexico. El objetivo de este estudio fue hacer una adaptación cultural del cuestionario del balance trabajo-salud (WHBq; (Gragnano et al., 2017) al idioma español y proporcionar evidencia mediante el análisis factorial, la confiabilidad y validez. Este instrumento se compone de tres escalas: Incompatibilidad trabajo-salud (WHI), clima de salud (HC) y apoyo externo (ES), con un total de 17 ítems. Este se aplicó a una muestra de trabajadores mexicanos (n = 316). El análisis factorial confirmatorio reveló un modelo de tres factores reproducido en la estructura original, el cual mostró un buen ajuste (CFI = 0.950; SRMR = 0.051; RMSEA = 0.069). La confiabilidad de cada factor y del cuestionario en su totalidad fue satisfactorio (ω mayor a 0.70). El AVE fue inferior a 0.50 solo en ES. Se discuten las soluciones para este problema. La validez de constructo se evaluó por criterio externo. El WHBq en su versión al español mostró adecuadas propiedades psicométricas y su relación teórica consistente con variables externas. Con estos resultados se confirma que este instrumento es una herramienta válida y confiable para su uso en México.

BackgroundTraffic events where motorcyclists are involved are a phenomenon increasingly frequent in Mexico. The use of less fuel and the practical to drive this vehicle makes the motorcycle a convenient mean of transport for a large sector of the population. For this reason, the objective is to analyse the associated factors to severe injuries of motorcyclists involved in traffic events in the Guadalajara metropolitan area and the municipality of Zapotlanejo in Jalisco, Mexico.MethodsThis is a cross-sectional study made to injured motorcyclists in the Guadalajara metropolitan area and the municipality of Zapotlanejo who were care in the Antiguo Hospital Civil de Guadalajara “Fray Antonio Alcalde”. The people selected were drivers or occupants of the motorcycle crashed, of any sex and age and the traffic event in what they were involved. A model of logistic regression was performed, which included the above variables with a p = <0.25.ResultsThe risk factors for severe injuries were: the motorcycle does not work correctly before the accident (OR 76.89, 2.08–2839.25), the motorcyclist deemed to have committed a traffic violation at the time of the event (OR 6.88, 1.30–36.26), the injured resident in the Guadalajara metropolitan area (OR 7.58, 1.15–50.17), drive a motorcycle unknowing if was “salvage” or not (OR 6.88, 1.30–36.26). The factors that reduce the risk were: drive other motorcycle except Italika (OR 0.06, 0.008–0.41) and have had the crash in a straight road or in a crossroad (OR 0.10, 0.02–0.61).ConclusionsThere are elements of the motorcyclist, the motorcycle and the physical environment that increase or decrease injury severity of motorcyclists without health insurance. For this public health problem could be necessary promote and create more awareness about road safety in motorcyclists. Not only promote the use of helmet, require support other recommendations about motorcycle and physical environment.
