A busca por passageiros variava, sendo possível ficar em pontos fixos ou circular pela cidade. As condições ambientais demandavam cuidados como o uso de protetor solar e hidratação. A autonomia da profissão permitia organizar o próprio expediente e o ganho mensal. Entretanto, houve queixas relativas à falta de direitos previdenciários e ao fato de que a flexibilidade geraria uma sobrecarga de trabalho que poderia trazer prejuízos à saúde. Riscos foram identificados em acidentes de trânsito e violência urbana. Os relatos acerca das relações com os colegas mostraram um ambiente amistoso, e as relações com os passageiros eram definidas por cada situação, abrangendo desde interações objetivas até conversas pessoais.(AU)

The research had as general objective to analyze the activity and the work of motorcycle taxi drivers in Sobral, Ceará. Specific objectives were to understand: (a) the activity performed and the real of activity; (b) the prescriptions; (c) informal rules and (d) professional relationships. The investigation adopted the theoretical framework of the Clinic of Activity. Eight motorcycle taxi drivers participated in the investigation. Inspired by the instruction to the double method, semi-structured interviews were conducted. The audio of the interviews was transcribed and underwent constructive-interpretive analysis. The results showed that the activity was regulated by the city and depended on the maintenance of the instruments used. The working hours were organized by a collective labor rule related to the opening hours of schools and universities. The looking-for for passengers also varied: it was possible to stay at fixed points or move around the city. Environmental conditions required care such as the use of sunscreen and hydration. The profession's autonomy made it possible to organize its own hours and monthly earnings. However, there were complaints regarding the lack of social security rights and that flexibility would create an overload of work that could harm health. Risks have been identified in traffic accidents and urban violence. Reports about relationships with colleagues showed a friendly atmosphere. Relations with passengers were defined by each situation, ranging from objective interactions to personal conversations.(AU)

Noise Exposure Among Motorcycle Riders: A Scoping Review

@#This scoping review aimed to determine the dosage of noise exposure among motorcycle riders and the sources contributing to a rider’s noise exposure. A systematic search of several scientific databases was conducted from 1981 until 2021. Eligible articles were included into the defined criteria. The dosage of noise exposure, sources, and standardization method were extracted. A total of 37 studies were included. There was scarce publication regarding the exact level of noise exposure experienced by the riders. There was, however, abundant evidence on indirect sources of noise exposure for riders, which requires further critical analysis. The dosage of noise exposure among riders was significantly higher than the recommended level. Seven sources were determined to generate noise which could potentially affect the riders, presented in this paper along with their respective evidence.

Prevalence and correlates of erectile dysfunction among long-distance commercial vehicle drivers and commercial motorcycle riders in Ibadan Nigeria: a comparative cross-sectional study

Background: Erectile dysfunction (ED) is a global public health problem that affects the quality of life, interpersonal, occupational, and social functioning of sufferers. Despite being high-risk groups, there is a paucity of data on erectile dysfunction among commercial vehicle drivers and motorcycle riders. Objectives: We aimed to determine and compare the prevalence and factors associated with ED among long-distance commercial vehicle drivers (CVDs) and commercial motorcycle riders (CMRs) in Ibadan, Nigeria. Methods: We used a comparative cross-sectional study design to enroll eligible male respondents in selected motor/motorcycle parks within Ibadan metropolis. Interviewer administered questionnaires were used to elicit sociodemographic/health-related characteristics, and ED status among participants. Data was analyzed using STATA version 12. Chi-square and Binary logistic regression were conducted to explore the association between ED and other covariates. Analyses were performed at 5% significance level. Results: The prevalence of ED was significantly higher among motorcycle riders than vehicle drivers (71.4% vs 47.4%, p = 0.001). Predictors of ED among CMRs were monogamous marriage type and history of perineal injury; while among CVRs were aged above 40-years, history of perineal injury, and current use of alcohol. Conclusion: There is a need for public education and awareness programmes on ED to reduce the burden and improve well-being in these populations

Injury patterns in elderly cyclists and motorcyclists presenting to a tertiary trauma centre in Singapore

INTRODUCTION@#With Singapore's ageing population, there are increasing numbers of elderly cyclists and motorcyclists. Compared to younger riders, this cohort sustains more injuries and has poorer outcomes. This study aimed to describe and compare patient demographics, injury patterns and outcomes among elderly cyclists and motorcyclists at a Level 1 trauma centre.@*METHODS@#Data of all cyclists, motorcyclists and pillion riders aged 65 years and above who presented to the emergency department after accidents from 1 January 2013 to 31 December 2017 was extracted from the hospital's trauma registry and reviewed.@*RESULTS@#Cyclists and motorcyclists formed 42.0% and 58.0%, respectively, of 157 recruited patients. At the time of the accident, 40.8% of the patients were employed. The mean age of the patients was 71.6 ± 5.8 years. Extremities and pelvic girdle injuries (61.1%) were the most frequent, followed by chest injuries (48.4%), and head and neck injuries (40.1%). Among severe injuries (defined as Abbreviated Injury Scale score ≥ 3), chest injuries (39.5%) were the most common, followed by head and neck injuries (36.3%). The overall mortality rate was 9.6%, with cyclists at nearly three times the risk compared to motorcyclists. More cyclists than motorcyclists (18.2% vs. 11.0%) required intensive care. There were no significant differences in the length of hospital stay between cyclists and motorcyclists.@*CONCLUSION@#Elderly riders have unique injury patterns and consume significant healthcare resources. Trauma systems need to acknowledge this changing injury epidemiology and equip trauma centres with the necessary resources targeted at elderly patients. Future work should focus on strategies to minimise extremity and chest injuries.

Epidemiologic study of traffic crash mortality among motorcycle users in Iran (2011-2017) / 中华创伤杂志(英文版)

PURPOSE@#Motorcycle accident is a major cause of road traffic injuries and the motorcyclists are considered as vulnerable road users. The present study aimed to determine the epidemiological characteristics of fatal motorcycle crashes in Iran.@*METHODS@#In this cross-sectional study, a total of 28,356 motorcycle traffic fatalities registered in the Legal Medicine Organization of Iran were analyzed during the period between March 2011 and March 2017. The examined variables included demographic characteristics, helmet use, crash mechanisms, crash location, position state, type of counterpart vehicle, cause of death and place of death. In the study, road traffic mortalities involving drivers and/or passenger of motorcycles were included. Cases or events registered without these conditions were excluded from the study. To analyse the data, SPSS statistics 25 and GraphPad Prism 8 softwares were used.@*RESULTS@#Of the 122,682 fatal traffic injury cases, 28,356 (23.1%) were motorcycle users, of whom 95.3% were male and 4.7% were female. Most of the motorcycle fatalities belonged to the age group of 18-24 years (29.1%). Head trauma was the major cause of death (59.0%). Also, the overall proportion of safety helmet use among motorcycle crash victims was estimated at 37.4%. Most of the road traffic crash cases (46.8%) happened out of city and half of people (49.9%) died in hospital. About 77.4% of the victims were motorcycle riders and 21.1% were pillion passengers. The highest rate of mortality belonged to the self-employed (38.4%) and then workers (21.8%) and students (10.2%). In addition, most fatalities occurred in people with low education (77.5%) and the least occurred in university graduates (5.5%). Among 31 provinces of Iran, Fars had the highest (9.3%) occurrence rate and Kohgiluyeh and Buyer-Ahmad had the lowest (0.5%). Most of the crash mechanisms were due to motorcycle-vehicle crashes (80.2%), followed by rollover (9.8%).@*CONCLUSION@#Comprehensive public education and special rules are needed to reduce the rate of deaths in motorcycle crashes.

Prevalence and factors associated with effective helmet use among motorcyclists in Mysuru City of Southern India

BACKGROUND@#Helmet use reduces the risk and severity of head injury and death due to road traffic crash among motorcyclists. The protective efficacy of different types of helmets varies. Wearing firmly fastened full-face helmet termed as effective helmet use provides greatest protection. This study estimates the prevalence and factors associated with effective helmet use among motorcyclists in Mysuru, a tier II city in Southern India.@*METHODS@#Cross-sectional road side observational study of 3499 motorcyclists (2134 motorcycle riders and 1365 pillion riders) at four traffic intersections was done followed by interview of random sample of 129 of the above riders. Effective helmet use proportion and effective helmet use per 100 person-minute of observation was calculated. Multivariate logistic regression analysis was done to identify factors associated with effective helmet use.@*RESULTS@#Prevalence of effective helmet use was 28 per 100 riders and 19.5 per 100 person-minute of observation in traffic intersections. Prevalence rates of effective helmet use was higher among riders (34.5% vs pillion riders 18.1%), female riders (51.3% vs male riders 26.8%), and male pillion riders (30.5% vs female pillion riders 13.7%). Riders commuting for work and school and those ever stopped by the police in the past 3 months had significantly higher odds of effective helmet use.@*CONCLUSION@#Despite helmet use being compulsory by law for motorcyclists, the effective helmet use was low in Mysore. Strict enforcement and frequent checks by the police are necessary to increase the effective helmet use.

Crashes and Traffic Signal Violations Caused by Commercial Motorcycle Couriers

BACKGROUND: Motorcycles are one of the important members of commercial transportation because of the convenient use during congested traffic conditions and the ease of parking in narrow streets. This study investigates the characteristics of crashes and traffic signal violations caused by motorcycle couriers. METHODS: From the national compensation data, this study analyzed the traffic crashes caused by 671 motorcycle couriers. RESULTS: Among 671 injured couriers, 50.6% were aged less than 40 years, 49.2% run in a small business of < 5 employees, and 47.2% had work experience of < 6 months. Motorcycle crashes occurred mainly due to “rider overturned alone” (67.5%), in the daytime (73.5%), or on cloudy or clear days (77.2%). However, the violation rate caused by motorcycle couriers was high in couriers in a small business of < 5 employees (13.9%), with work experience of < 6 months (13.9%), on cloudy or clear days (12.4%), on an intersection (29.8%), in the type of “crash with a vehicle” (31.2%), or in a death accident (35.7%). CONCLUSION: The findings of this study can be used as a baseline in devising policies for preventing crashes of motorcycle couriers.

Severity and injury characteristics among matched hospitalized motorcycle drivers and their passengers / 中华创伤杂志(英文版)

PURPOSE@#After car accident, motorcycle accident ranks as the second leading cause of traffic fatality in Iran. This study aimed to compare the severity and clinical presentations between drivers and passengers under the same injury circumstance.@*METHODS@#This study was conducted in the trauma center of Shiraz, Iran in 2017. Data on demographics, triage level, blood pressure, respiratory rate, Glasgow coma scale (GCS), injured body region, injury severity score (ISS), revised trauma score (RTS), and result of accident were compared between pairs of drivers and passengers. The agreement of any type of injury between drivers and passengers evaluated by Kappa test.@*RESULTS@#This study included 143 matched pairs of drivers and passengers. Most of the pairs (84.5%) did not use helmet and 77.2% of the riders do not have driving license. ISS was significantly higher in drivers than passengers. In the unmatched pairs, drivers and passengers showed no difference in sustaining injuries in the face, head & neck, chest and soft tissue, but drivers were found more likely to suffer from injuries in the abdomen, extremities, pelvis and spine than passengers. Once one part of the matched pair suffered injury in the head & neck, face, chest, abdomen, extremities and soft tissue & skin injury, the probability that the other part had an injury in the same region was 50%, 9%, 13%, 7%, 22% and 34% respectively. Kappa value for these body regions was 0.006, 0.009, -0.006, 0.068, 0.063 and 0.001, respectively, which was significant in abdomen and extremities.@*CONCLUSION@#Although drivers had higher level of injury severity and some different injury distributions, we recommend equal treatment to drivers and passengers. We also recommend related authorities to develop policies on helmet use, driving license and third-party insurance.

Likert Scale vs. Visual Analogue Scale on Vehicle Seat Discomfort Questionnaire: A Review

Abstract@#Discomfort measurement has usually been attempted by asking the participants to rate the scale of their discomfort which commonly termed as a subjective scale. Various studies had conducted the discomfort level on vehicle seat by using Visual Analogue Scale (VAS) and Likert scale. VAS is a tool that use to measure a discomfort or characteristics in range across a continuum of values. Meanwhile, Likert-scale is a tool consist of items that require respondents to rate their degrees of comfort or discomfort with various declarative statements. Thus, the purpose of this study is to review, discuss and compare between the VAS and Likert scale used on the development and assessment of sitting discomfort survey in seat vehicles. The literature on various topics related to questionnaire development on discomfort in seat vehicle were collected from electronic databases. Four high-quality studies were eligible and met the inclusion and exclusion criteria. Overall, there is no evidence and conclusion that neither visual analogue scale nor Likert scale are better to one another. Therefore, it can be concluded that either of this scale still applicable for the ergonomic research application as both of this scale have their own pros and cons.

Introduction: Traffic accidents are a serious public health problem, however, their socio-economic impact has not been described in Paraguay. Objectives: to determine the socioeconomic impact of motorcycle accidents in victims <19 years of age in 2016. Materials and Methods: this was a descriptive, observational, retrospective study. All patients aged ≤19 years who were admitted to the Trauma Hospital (TH) with a history of a motorcycle accident in 2016 were included. The data and costs were obtained from the Statistics Department and the Admissions Department of the TH. Results: 700 patients were included, all of whom were admitted to the TH due to a motorcycle accident. The average age of the patients was 15.6 ± 4.33 years. 78% (546/700) were male. Of those injured, 450 (64.2%) were drivers and 250 (35.7%) were passengers. The average age of the drivers was 17 ± 4.3 years (range 11-19 years) and that of the passengers was 12.3 ± 4.4 years (range <1-19 years). Among the drivers, only 50.4% (227/450) were of the legal age to obtain a driver's license. Only 7.7% (54/695) of the victims wore a helmet at the time of the accident. 89.2% (625/700) of patients required hospitalization stays of 2 or more days of length, of which 7.6% required PICU admission. The mean number of regular ward hospitalization days and PICU days were 11.04 days (SD 14.85 days) and 16.57 days (SD 23 days), respectively. 25.1% (176/700) had some degree of disability or long-term effects and 5.4% (38/700) died. The direct costs per hospitalization per day in the ward and in the PICU were US$ 275.4 and 737.2, respectively. The direct costs for motorcycle accidents in 2016 was US$ 2,587,179.2. The years of potential life lost (YPLL) in 2016 were 2159 years. Conclusions: The socioeconomic impact of motorcycle accidents represents an extremely high social cost, stemming from a preventable cause of death.

Método de dos fases para el problema de ruteo de mensajeros en motocicleta con ventanas de tiempo / Two-phase method for motorcycle messenger routing problem with time windows / Método de duas fases para o problema de roteiro de mensageiros de motocicleta com janelas de tempo

RESUMEN Se presenta un método para la solución del problema de ruteo de mensajeros en motocicleta con ventanas de tiempo. En este se identifican dos fases: en la primera, se conforman grupos de clientes, cada grupo es asignado a una ruta y cada ruta es atendida por un vehículo; en la segunda, por medio de un modelo de programación lineal entera mixta, se hace un ruteo para cada una de las agrupaciones respetando las ventanas de tiempo estrictas de algunos clientes. Para validar el método, se utilizó como caso de estudio el área de mensajería de un centro de servicios compartidos de Cali, Colombia. Los resultados muestran que, al probar diferentes métodos de agrupación (fase 1), no se influye de forma significativa en el tiempo total de permanencia del vehículo en la ruta; en cambio, una reagrupación de los clientes después del ruteo (fase 2), mejora considerablemente la duración total de la ruta, aunque en algunos casos, aumenta la distancia recorrida por el vehículo.

ABSTRACT In this work, a method to solve a motorcycle messenger routing problem with time windows is presented. This has two phases: in the first one, clusters of clients are formed, each group is assigned to a route and each route is served by a vehicle; in the second phase, through a mixed integer linear programming model the routing for each cluster is made while respecting hard time windows of some clients. To validate the method, the mail delivery section of a shared service center in Cali - Colombia is used as case study The results show that, when testing different clustering methods (phase l) these do not significantly influence the vehicle's duration on the road; On the other hand, regrouping the clients after routing (phase 2) can considerably improve the total duration of the route, although in some cases, increasing the distance traveled by the vehicle.

RESUMO Neste trabalho se apresenta um método para a solução do problema de roteiro de mensageiros de motocicleta com janelas de tempo. Nele identificam-se duas fases: na primeira, conformam-se grupos de clientes, cada grupo é atribuído a uma rota e cada uma delas é servida por um veículo; na segunda, por meio de um modelo de programação linear todo misto, faz-se um roteiro para cada uma das agrupações respeitando as janelas de tempo estritas de alguns clientes. Para validar o método, usou-se como caso de estudo a área de mensageria de um centro de serviços compartilhados na cidade de Cali, na Colômbia. Os resultados mostram que ao testar diferentes métodos de agrupamento (fase l), não influem de maneira significativa no tempo total de permanência do veículo na rota; por outro lado, um reagrupamento dos clientes após do roteiro (fase 2), melhora consideravelmente a duração total do percurso, porém em alguns casos, aumenta a distância percorrida pelo veículo.

Fatores associados a acidentes de trabalho entre profissionais mototaxistas / Factors associated with accidents at work among motorcycle taxi drivers / Factores asociados a accidentes de trabajo entre profesionales de mototaxis

O número de acidentes de trânsito envolvendo motocicleta é cada vez maior, o que expõe o profissional mototaxista à ocorrência de acidentes de trabalho. O presente estudo tem como objetivo estimar a incidência anual de acidentes de trabalho entre profissionais mototaxistas e os fatores associados a estes agravos segundo características sociodemográficas, características profissionais, condições de trabalho e presença de sintomas osteomusculares. Trata-se de estudo transversal de caráter analítico com amostra composta por 123 mototaxistas cadastrados na Associação de Mototaxistas de Jequié (taxa de resposta 77,8%). Para análise estatística, foi utilizada a técnica de regressão logística, com cálculo das razões de incidência, intervalo de confiança (95%) e nível de significância p ≤ 0,05. A incidência anual de acidentes de trabalho entre mototaxistas foi de 26,8%. Foi observada, ainda, uma incidência expressiva de acidentes entre aqueles que relataram possuir outra atividade remunerada além do serviço de mototáxi (86,7%), com associação estatisticamente significante (p = 0,03). O desempenho de duas profissões parece predispor o mototaxista a maior ocorrência de acidentes com o veículo, sendo considerado um importante problema de saúde pública.

The number of traffic accidents involving motorcycles is increasing, this exposes motorcycle taxi drivers to work accidents. This study aims to estimate the incidence of accidents at work among motorcycle taxi drivers and factors associated with these problems according to sociodemographic characteristics, professional characteristics, working conditions and the presence of musculoskeletal symptoms. It is a cross-sectional study of analytical character with sample composed of 123 registered motorcycle taxi drivers at the Associação de Mototaxistas de Jequié (77.8 response rate). For statistical analysis, we used the logistic regression technique, with calculation of incidence ratio, confidence interval (95%), and p ≤ 0.05 significance level. The annual incidence of work accidents with motorcycle taxi drivers was 26.8%. A significant incidence of accidents was observed among those who reported having another remunerated activity in addition to the taxi service (86.7%), with statistically significant association (p = 0.03). The performance of two professions seem to predispose the motorcycle taxi drivers to more of accidents with the vehicle and is considered an important public health problem.

Se viene aumentando el número de accidentes de tráfico con motocicletas, lo que expone al profesional mototaxista a accidentes de trabajo. El presente estudio pretende estimar la incidencia anual de accidentes en el trabajo entre profesionales mototaxistas y los factores asociados a estas enfermedades según las características sociodemográficas, características profesionales, condiciones de trabajo y presencia de síntomas musculoesqueléticos. Este estudio es transversal, de carácter analítico, con una muestra compuesta por 123 mototaxistas registrados en la Associação de Mototaxistas de Jequié (una tasa de respuesta del 77,8%). Para el análisis estadístico, se aplicó la técnica de regresión logística, con cálculo de razones de incidencias, intervalo de confianza (95%) y nivel de significación p ≤ 0,05. La incidencia de accidentes fue de un 26,8% en los mototaxistas. Se observó una incidencia significativa de accidentes entre aquellos que reportaron tener otra actividad remunerada, además del servicio de mototaxi (86,7%), con una asociación estadísticamente significativa (p = 0,03). Se concluye que el manejo de dos profesiones puede predisponer al profesional a una mayor ocurrencia de accidentes con el vehículo y se considera un importante problema de salud pública.

Accidentes de moto: costo médico/económico en un hospital municipal de la Ciudad de Buenos Aires / Motorcycles accidents: medical and economic cost at a public hospital in Buenos Aires City

A nivel mundial, los accidentes de tránsito aportan aproximadamente 1.25 millones de muertes anuales; es una de las principales causas de muerte en personas jóvenes y la primera entre los 15 y 29 años de edad. La tasa de accidentes aumentó en la última década, posiblemente debido al incremento del parque automotor y del uso de motocicletas. Se realizó un estudio retrospectivo descriptivo sobre los casos atendidos en el Hospital Carlos G. Durand, Buenos Aires (CABA), Argentina, desde enero de 2013 hasta diciembre de 2015, con el objetivo de representar el costo médico que estos generan en nuestro Hospital. De un total de 4368 pacientes atendidos en guardia, a causa de accidentes de tránsito, el 67% (2926 pacientes) fue provocado por motocicletas, de estos, el 18% requirió internación. Hubo predominio de varones y de lesiones en miembros inferiores. Las internaciones variaron entre 5 y 150 días, con 2.1 cirugías promedio por paciente. El gasto total del tratamiento fue de 16 767 037$, lo que en 2014 representaban unos 17 936 US$ por paciente. Estos resultados reflejan parcialmente el costo de dichos accidentes, ya que no se tiene en cuenta otros parámetros como la caída de días laborales; es por esto que se debe generar conciencia y crear políticas de prevención y educación vial más rigurosas, necesarias para poder evitar los accidentes que incrementan el gasto en afecciones evitables.

Traffic accidents cause 1.25 million deaths per year worldwide, being one of the leading causes of death in young people, and the first cause between the ages of 15 - 29. There has been an increase in accidents in the last 10 years, one of the reasons for this is the increase in the sales of motorcycles and its use. We present a retrospective study about the patients who received attention at Carlos G. Durand Hospital, (CABA, Buenos Aires , Argentina) from January 2013 to December of 2015, with the intention of showing the medical and economic impact this accidents cause. Of a total of 4368 incoming patients assisted, due to traffic accidents, 67% (2926) were the result of motorcycle crashes; 18% of them required hospitalization. Males, and lower limbs lesions were predominant. Hospitalizations varied between 5 and 150 days, with 2.1 average surgeries per patient. The total cost was 16 767 037$, and in 2014 it represented 17 936 US$ per patient. These results show only partially the impact these accidents produce, because there are factors (like missing working days) that were unaccounted for. This is why it is necessary to generate awareness and develop more rigorous road safety and prevention policies, necessary to avoid accidents that increase spending on preventable conditions.
