Alcohol is a risk factor for helmet non-use and fatalities in off-road vehicle and motorcycle crashes.

OBJECTIVES: Off-road vehicle (ORV) and motorcycle use is common in Canada; however, risk of serious injury is heightened when these vehicles are operated without helmets and under the influence of alcohol. This study evaluated the impact of alcohol intoxication on helmet non-use and mortality among ORV and motorcycle crashes. METHODS: Using data collected from the Nova Scotia Trauma Registry, a retrospective analysis (2002-2017) of ORV and motorcycle crashes resulting in major traumatic brain injury was performed. Patients were grouped by blood alcohol concentration (BAC) as negative (< 2 mmol/L), legally intoxicated (2-17.3 mmol/L) or criminally intoxicated (> 17.3 mmol/L). Logistic regression models were constructed to test for helmet non-use and mortality. RESULTS: A total of 424 trauma patients were included in the analysis (220 ORV, 204 motorcycle). Less than half (45%) of patients involved in ORV crashes were wearing helmets and 65% were criminally intoxicated. Most patients involved in motorcycle crashes were helmeted at time of injury (88.7%) and 18% were criminally intoxicated. Those with criminal levels of intoxication had 3.7 times the odds of being unhelmeted and were 3 times more likely to die prehospital compared to BAC negative patients. There were significantly increased odds of in-hospital mortality among those with both legal (OR = 5.63), and criminal intoxication levels (OR = 4.97) compared to patients who were BAC negative. CONCLUSION: Alcohol intoxication is more frequently observed in ORV versus motorcycle crashes. Criminal intoxication is associated with helmet non-use. Any level of intoxication is a predictor of increased in-hospital mortality.

Comparison of Traumatic Spinal Fracture Patterns Between Motorcyclists and Occupants of Other Non-heavy Motor Vehicles: A Report from the National Spinal Cord and Column Injury Registry of Iran (NSCIR-IR).

OBJECTIVES: To compare traumatic spinal injury patterns between motorcyclists and occupants of other non-heavy motor vehicles using data from the National Spinal Cord and Column Injury Registry of Iran (NSCIR-IR). METHODS: All drivers/riders and passengers of motorcycles, cars, pick-up trucks, and vans registered between January 2017 to July 2023, met the inclusion criteria for the present study. The logistic regression models were used to compare the patterns of vertebral fracture between the two groups. RESULTS: 1726 spinal fracture patients were identified, 385 (22.3%) motorcyclists and 1341 (77.7%) car occupants with mean ages 33.2±14.3 and 36.1±13.6 years, respectively (P<0.001). Only 45 (11.7%) motorcyclists used helmets, whereas 856 (63.8%) car occupants used seat belts (P<0.001). The average numbers of fractured vertebrae were 3.9±1.4 and 3.7±1.1 among car occupants and motorcyclists, respectively (P=0.004). The proportions of motorcyclists and car occupants with injuries in each spinal region are as follows: lumbar (50.5% of motorcyclists vs. 40.4% of car occupants; P=0.003), thoracic (39.2% vs. 30.9%; P=0.01), cervical (24.3% vs. 37.0%; P<0.001) and sacral (1.3% vs. 7.5%; P<0.001). The AO Spine type C injuries were present in 6.1% of motorcyclists and 10.1% of car occupants (P=0.03). CONCLUSION: Motorcyclists were younger, less educated, had a higher proportion of males, and less commonly used safety devices than car occupants. The most commonly fractured spine region among both groups was the lumbar region. The cervical and sacral vertebrae fractures were significantly more common in car occupants, whereas the thoracic and lumbar vertebrae fractures were significantly more common in motorcyclists.

[Trends in motorcycle road deaths in Colombia, 2008-2021Tendências de mortalidade por acidentes de motocicleta na Colômbia, 2008-2021]. / Tendencias en la mortalidad por accidentes de tránsito en motocicleta en Colombia, 2008-2021.

Objective: To identify trends in motorcycle road deaths in Colombia between 2008 and 2021. Methods: An observational and descriptive study of trends in motorcycle road deaths was conducted using official death records from 2008 to 2021. Jointpoint Poisson regression analysis was performed to detect inflection points in mortality rates specific to age, sex, and area of residence. Results: A total of 28 200 motorcycle road deaths were identified during the period; 24 271 men and 3 929 women died. Of the deaths, 74.1% occurred in urban areas and 25.9% in rural areas. In rural areas, there was an increasing trend in fatalities in young adults of both sexes during the period. The same occurred in men over 65 years of age. In urban areas, there was an upward trend in fatalities in the age group from 45-64 for both sexes during the period. Only one inflection point was detected, in 2015, showing a downward trend in adolescent females. Conclusion: The trend in motorcycle road deaths in Colombia continued to rise during the 2008-2021 period, both in rural areas for young adults and in urban areas for middle-aged adults.

The prevalence of helmet use in motorcyclists around the world: a systematic review and meta-analysis of 5,006,476 participants.

Road traffic injuries present a significant public health burden, especially in developing countries. This systematic review and meta-analysis synthesized global evidence on motorcycle helmet use prevalence by including 299 records across 249 articles involving 5,006,476 participants from 1982 to 2022. The findings revealed a declining trend in helmet use prevalence over the past four decades, with an overall prevalence of 48.71%. The meta-regression analysis did not find any statistically significant change in the overall prevalence. Subgroup analysis showed higher helmet use prevalence in observation/survey records (54.29%) compared to crashed patient records (44.84%). Riders/Motorcyclists demonstrated a higher likelihood of wearing helmets than passengers in both observation/survey records (62.61 vs. 28.23%) and crashed patient records (47.76 vs. 26.61%). Countries with mandatory helmet use laws had higher helmet usage prevalence compared to those without (52.26 vs. 37.21%). The African continent had the lowest helmet use rates, while Latin America and the Caribbean regions had higher rates. This study provides a comprehensive overview of global helmet use prevalence, emphasizing disparities between high and low-income countries, variations in law enforcement, and trends over four decades. Targeted interventions are necessary to improve helmet-wearing habits, especially among passengers and regions with low usage rates. Effective legislation and awareness campaigns are crucial for promoting helmet use and reducing road traffic injuries burden.

Prediction of the burden of road traffic injuries in Iran by 2030: Prevalence, death, and disability-adjusted life years.

PURPOSE: Road traffic accidents pose a global challenge with substantial human and economic costs globally. Iran experiences a high incidence of road traffic injuries, leading to a significant burden on society. This study aims to predict the future burden of road traffic injuries in Iran until 2030, providing valuable insights for policy-making and interventions to improve road safety and reduce the associated human and economic costs. METHODS: This analytical study utilized time series models, specifically autoregressive integrated moving average (ARIMA) and artificial neural networks (ANNs), to predict the burden of road traffic accidents by analyzing past data to identify patterns and trends in Iran until 2030. The required data related to prevalence, death, and disability-adjusted life years (DALYs) rates were collected from the Institute for Health Metrics and Evaluation database and analyzed using R software and relevant modeling and statistical analysis packages. RESULTS: Both prediction models, ARIMA and ANNs indicate that the prevalence rates (per 100,000) of all road traffic injuries, except for motorcyclist road injuries which have an almost flat trend, remaining at around 430, increase by 2030. Based on estimations of both models, the rates of death and DALYs due to motor vehicle and pedestrian road traffic injuries decrease. For motor vehicle road injuries, estimated trends decrease to approximately 520 DALYs and 10 deaths. Also, for pedestrian road injuries these rates reached approximately 300 DALYs and 6 deaths, according to the models. For cyclists and other road traffic injuries, the predicted DALY rates by the ANN model increase to almost 50 and 8, while predictions conducted by the ARIMA model show a static trend, remaining at 40 and approximately 6.5. Moreover, these rates for the prediction of death rate by the ANN model increased to 0.6 and 0.1, while predictions conducted by the ARIMA model show a static trend, remaining at 0.43 and 0.07. According to the ANN model, the predicted rates of DALY and death for motorcyclists decrease to 100 and approximately 2.7, respectively. On the other hand, predictions made by the ARIMA model show a static trend, with rates remaining at 200 and approximately 3.2, respectively. CONCLUSION: The prevalence of road traffic injuries is predicted to increase, while the death and DALY rates of road traffic injuries show different patterns. Effective intervention programs and safety measures are necessary to prevent and reduce road traffic accidents. Different interventions should be designed and implemented specifically for different groups of pedestrians, cyclists, motorcyclists, and motor vehicle drivers.

Mortalidad en accidentes por moto en Venezuela, y su relación con Políticas Públicas de seguridad vial y preventiva,1996-2018 / Mortality in motorcycle accidents in Venezuela and relationship with public road safety and preventive policies, 1996 - 2018

Los accidentes de tránsito son un problema de salud pública de gran magnitud y gravedad, en las Américas; Venezuela ocupa un lugar destacado por su alta incidencia. El objetivo de la investigación es establecer la relación entre las políticas públicas para la prevención de los accidentes de motocicletas, y las tasas de mortalidad. Metodología: Estudio documental retrospectivo de las políticas viales y las tasas de mortalidad específicas de lesionados por accidentes de motocicletas en Venezuela durante el período 1996-2018. Resultados: como causa de muerte en Venezuela (2000-2018), representa casi 7% del total, entre 6 a 50% del total de las muertes por accidentes de tránsito terrestre y se mantiene muy alta al final del período, con fallecidos por motocicletas sobre 25%. La elevación de la curva endémica de mortalidad ocurrió simultáneamente al aumento en la producción e importación de motocicletas, y cayó durante la crisis económica, en el año 2014. La legislación actualizada mas no acatada en esta materia, es notoria Conclusiones: Los accidentes de motocicleta son un problema de salud pública de primer orden en Venezuela asociadas al clima económico y social, las tasas de mortalidad tuvieron su máxima meseta de elevación durante la bonanza petrolera 2005-2013. Las políticas asociadas a la prevención de accidentes viales en moto están fragmentadas, son ineficientes y reactivas a situaciones complejas, deficientemente aplicadas por los organismos de tránsito responsables a escala nacional, regional y municipal.

Introduction. Traffic accidents are a public health problem of great magnitude and gravity in the Americas; Venezuela occupies a prominent place for its high incidence. The objective of the research is to establish the relationship between public policies for the prevention of motorcycle accidents, and mortality rates. Methodology: Retrospective documentary study of road policies and specific mortality rates of those injured by motorcycle accidents in Venezuela during the period 1996-2018. Descriptive statistical analysis with trend lines, frequency distributions and annual average rates. Results: cause of death in Venezuela (2000-2018), represents almost 7% of the total. The burden of motorcycle injury deaths represents between 6 to 50% of total road traffic fatalities and remains very high at the end of the period, with motorcycle fatalities over 25%. The elevation of the endemic mortality curve occurred simultaneously with the increase in the production and import of motorcycles, and fell concomitantly with the economic crisis in 2014. Conclusions: Motorcycle accidents are a public health problem of the first order in Venezuela associated with the economic and social climate, mortality rates had their maximum plateau of elevation during the oil economic boom 2005-2013. The policies associated with the prevention of road accidents by motorcycle are fragmented, inefficient and reactive to complex situations and poorly applied by the responsible traffic agencies at national, regional and municipal level.

A Motorcycle Paramedic Increases the Survival Rate of Patients after OHCA.

Background and Objectives: Despite advancements in modern medicine, the survival rate of patients after out-of-hospital cardiac arrest (OHCA) remains low. The proportion of OHCA patients who could be saved under ideal circumstances is unknown. A significant portion of patients experience cardiac arrest due to irreversible conditions. The survival of patients with reversible causes depends on the prompt initiation of basic life support (BLS) and early defibrillation. In order to increase the chances of survival, the motorcycle paramedic (MP) project was implemented in Ljubljana in 2003. The MP is equipped with an AED. In the case of OHCA with a shockable rhythm, he performs defibrillation before the arrival of the emergency medical team (EMT). The aim of this study was to evaluate whether the MP, by reducing response times to OHCA patients, increases the survival and outcome of these patients compared to the EMT. Materials and Methods: A retrospective analysis of OHCA cases within the area covered by Ljubljana Emergency Medical Service (EMS) was conducted for the period from January 2003 to December 2022. Instances where the MP arrived at the scene before the EMT were considered MP interventions and classified as the MP group; all other interventions were classified as the EMT group. Results: Between January 2003 and December 2022, the EMT performed resuscitation on 3352 patients. In 316 cases, the MP was simultaneously activated and arrived at the scene before the EMT. The response time in the MP group was shorter compared to the EMT group (7.7 ± 4.1 min vs. 9.9 ± 6.5 min, p < 0.001). In 16 patients, return of spontaneous circulation (ROSC) was achieved before the arrival of the EMT. The MP group had a higher ROSC rate, a larger proportion of patients were discharged from the hospital and there were more patients with a good neurological outcome compared to the EMT group (44.3% vs. 36.9%, p = 0.009; 18.7% vs. 13.0%, p = 0.005; 15.9% vs. 10.6%, p = 0.004, respectively). Conclusion: This study has demonstrated that the implementation of the MP into the EMS in Ljubljana has resulted in shorter response times, an increased survival rate and improved neurological outcome for OHCA patients.

Research on pressure stability in an air cleaning and supplying system for motorcycle users.

The article introduces the air purification system arranged on motorcycles to help provide clean air for motorcycle users. This is a new system that is being researched and tested to help reduce the harmful effects of air pollution. First, an air purification system model is proposed and a mathematical model is built. SolidWorks software is used to design 3D models and evaluate the effectiveness of the system. Finally, the article focuses on analyzing the pressure change of the air purification system when passing through the newly designed mechanical structures of the system. By examining the variation of the air flow circulating through the system from 15 l/min to 40 l/min, it has been shown that the air pressure supplied to the motorcycle users is always guaranteed to fluctuate around the standard value of 101325 Pa. This is important because, in the tidal volume range, the volume of air moved into or out of the lungs during a normal breath, is about 6.5 l/min to 8 l/min with comfortable pressure equal or greater 101325 Pa. From the results of the pressure study, the system will decide to choose the output pressure control mode to help the user feel comfortable.

Patterns of Maxillofacial Injures Caused by Motorcycle Accidents

Abstract Introduction Motorcycles are used as a common means of transportation, and motorcycle accidents are responsible for a major portion of trauma injuries. Objectives The purpose of this study was to analyze the patterns of facial injuries in motorcyclists, to evaluate the types of injuries, and to investigate if the accidentrelated factors had any impact on the characteristics of the injuries. Methods This retrospective observational study included 74 patients with maxillofacial injuries following motorcycle-related accidents. Investigated data were divided into four main categories: sociodemographic, accident-related, injury-related, and treatment-related. Results All the patients were males with a mean age (±SD) of 25.03 (±9.986) years. Most accidents (n = 44, 59.4%) occurred in the evening. Most of the patients (n = 40, 54%) were traveling on motorcycle models that had maximum speed of over 120 km/h. Furthermore, 15 patients (18.9%) were under the influence of alcohol during the crashes and only one patient was wearing a helmet. Fractures of the maxillofacial bones were observed in 50 (67.5%) crash victims; 24 of them (48%) had middle third fractures, 11 (22%) had mandibular fractures, and 15 patients (30%) presented with a combination of lower, middle, and upper third fractures. Conclusion Almost all patients were not wearing helmets at the moment of the crash. The most common fractured site was the maxilla. The majority of the patients received surgical treatment. Increased enforcement of safety measures for riders and raising awareness about the dangers of motorcycle crashes are required measures to improve traffic safety and, ultimately, population health.

[Mortality and disability-adjusted life years in motorcyclists in Latin America and the Caribbean during the first decade of action for road safetyMortalidad y años de vida ajustados por discapacidad de los motociclistas en América Latina y el Caribe en la primera década de seguridad vial]. / Mortalidade e anos de vida ajustados por incapacidade de motociclistas na América Latina e Caribe na primeira década de segurança viária.

Objective: To identify the temporal trend in mortality and years of life lost to death or disability (DALY) due to motorcycle accidents in males from Latin America and the Caribbean from 2010 to 2019, using estimates produced by the Global Burden of Disease (GBD) study. Method: In this ecological study, the time series was analyzed using a piecewise linear regression model (joinpoint) to estimate and test the annual percent change and the average annual percent change with a 95% confidence interval. Results: The super-region defined by GBD 2019 as Latin America and the Caribbean ranked first globally in mortality and DALY for male motorcyclists aged 15-49 in 2019. Rates increased significantly from 2010 to 2013, with a significant reduction in both after this period. During the analyzed decade, the Tropical Latin America sub-region (Brazil and Paraguay) had the highest mortality and DALY rates in the population of interest; nevertheless, this was the only sub-region achieving a significant reduction in these rates. The Caribbean sub-region (Bermuda, Dominica, Suriname, Guyana, Belize, Bahamas, Puerto Rico, Saint Lucia, Dominican Republic, Haiti, Saint Kitts and Nevis, U.S. Virgin Islands, Grenada, Trinidad and Tobago, Barbados, Saint Vincent and the Grenadines, Antigua and Barbuda, Cuba e Jamaica) showed a significant increase in both rates over the same period, while Andean Latin America (Ecuador, Bolivia and Peru) and Central Latin America (Colombia, Costa Rica, El Salvador, Guatemala, Mexico, Nicaragua, Panama, Honduras, and Venezuela) remained stable. Conclusions: The data underscore the importance of developing surveillance actions aimed at preventing motorcycle accidents, since the observed declining rates are still insufficient to address the morbidity and mortality associated with road accidents as a public health problem.

Objetivo: Determinar la tendencia temporal de la mortalidad y los años de vida perdidos por muerte o ajustados por discapacidad (AVAD) de hombres por accidentes de motocicleta en América Latina y el Caribe en el período 2010-2019, a partir de las estimaciones del estudio de la carga mundial de enfermedades (CME). Métodos: En este estudio ecológico se analizaron las series temporales mediante el modelo de regresión lineal segmentada (joinpoint), con cálculo y comprobación del cambio porcentual anual y del cambio porcentual anual promedio, con un intervalo de confianza del 95%. Resultados: La región de América Latina y el Caribe definida por el estudio de la CME ocupó el primer lugar a nivel mundial en mortalidad y AVAD de motociclistas varones de 15 a 49 años en el 2019. Las tasas tuvieron un notable aumento del 2010 al 2013, y ambas registraron una reducción importante después de ese período. En la década analizada, la subregión de América Latina Tropical (Brasil y Paraguay) presentó las mayores tasas de mortalidad y de AVAD en la población de estudio, pero fue la única con una reducción importante de las mismas. La subregión del Caribe (Antigua y Barbuda, Bahamas, Barbados, Belice, Bermudas, Cuba, Dominica, Granada, Guyana, Haití, Islas Vírgenes de Estados Unidos, Jamaica, Puerto Rico, República Dominicana, Saint Kits y Nevis, San Vicente y las Granadinas, Santa Lucía, Suriname, y Trinidad y Tabago) mostró un aumento importante de ambas tasas, mientras que América Latina Andina (Bolivia, Ecuador y Perú) y América Latina Central (Colombia, Costa Rica, El Salvador, Guatemala, Honduras, México, Nicaragua, Panamá y Venezuela) se mantuvieron estables. Conclusiones: Los datos refuerzan la importancia de las actividades de vigilancia destinadas a prevenir los accidentes de motocicleta, puesto que la reducción observada de las tasas aún es insuficiente para abordar la morbimortalidad por accidentes de tráfico como problema de salud pública.

Profile of low and middle-income countries with increases versus decreases in road crash fatality population rates and necessity of motorcycle safety.

INTRODUCTION: Road crash fatalities have increased significantly in Low- and Middle- Income Countries (LMICs) between 2006 and 2016. This study presents how road safety characteristics have changed in LMICs by comparing data over time and relationships between the road crash fatality increase and a wide range of data from LMICs. Parametric and nonparametric methods are used to test significance. METHOD: There were 35 countries in the Latin America and Caribbean region, the Sub-Saharan Africa region, the East Asia and Pacific region, and the South Asia region, where the population rate of road crash fatalities consistently increased as per country reports, World Health Organization and Global Burden of Disease estimates. In these countries, the proportion of fatalities involving motorcycles (including powered two or three-wheelers) substantially increased (44%) over the same time (statistically significant). In these countries, the helmet-wearing rate was only 46% for all passengers. These patterns were not observed in LMICs with decreasing population fatality rates. RESULTS: Motorcycle helmet usage rates strongly correlate with decreasing fatalities per 10,000 motorcycles in Low-Income Countries (LICs) and LMICs. Effective interventions (including increasing helmet usage) are urgently needed for motorcycle crash trauma in LMICs, especially where the economy and motorization rapidly grow. National strategies for motorcycle safety, conforming to the Safe System principles, are recommended. CONCLUSIONS: For evidence-based policy formulation, there is a need to continue strengthening data collection, sharing, and use.

Traffic accident mortality of motorcyclists, pedestrians and hospital costs in the city of São Paulo

Introduction: the United Nations recognizes traffic accidents as a serious public health problem all over the world, because they are accompanied by a high morbidity and mortality rate. Traffic causes the death of approximately 1.3 million people and the disability of millions more.Objective: to evaluate mortality from traffic accidents among motorcyclists, pedestrians and hospital costs that occurred in the city of São Paulo, Brazil, from 1999 to 2019.Methods: this is a retrospective time series study with official micro data, collected by place of occurrence among motorcycle drivers, pedestrians and hospital costs from 1999 to 2019, in the city of São Paulo, SP, Brazil.Results: in the city of São Paulo, from 1999 to 2019, there were 144,186 thousand deaths resulting from land transport accidents, projecting 5,293 thousand deaths specifically with motorcyclists. Proportional mortality from was higher in the mean age group of 29 years, predominantly in males, with emphasis on white race/skin color. The costs per death stand out for motorcyclists with an average of R$: 49,078.18, with regard to deaths by sex, male predominated in relation to female.Conclusion: there was a high death rate, both in motorcyclists and pedestrians, with the latter having a higher average. Thus, these findings provide relevant information on the magnitude of the public health problem to guide us on control strategies for these causes.

Parental beliefs regarding adult and child motorcycle helmet-wearing practices in Vietnam.

From a global perspective, low helmet-wearing rates in children are an ongoing concern. International studies show adult helmet-wearing rates are consistently higher than those of children. Research also shows parents are highly influential in promoting healthy behavior in their children. Parent-focused helmet-wearing campaigns are a practical way to actively feature parents influencing helmet-wearing in children. The current study obtained anonymous parent-focused survey data on parent and child helmet-wearing practices, perceived affects of helmet use on children's health, and beliefs about brain injury prevention from a sample of Vietnams parents. Findings from this study are consistent with previous international research that shows adults wear helmets at higher rates than children. Data from this study may help those responsible for child helmet safety campaigns develop more effective child helmet-wearing campaigns, particularly in Southeast Asian countries.

Effective factors of improved helmet use in motorcyclists: a systematic review.

BACKGROUND: Road traffic injuries (RTI) are one of the most prominent causes of morbidity and mortality, especially among children and young adults. Motorcycle crashes constitute a significant part of RTIs. Policymakers believe that safety helmets are the single most important protection against motorcycle-related injuries. However, motorcyclists are not wearing helmets at desirable rates. This study systematically investigated factors that are positively associated with helmet usage among two-wheeled motorcycle riders. METHODS: We performed a systematic search on PubMed, Scopus, Web of Science, Embase, and Cochrane library with relevant keywords. No language, date of publication, or methodological restrictions were applied. All the articles that had evaluated the factors associated with helmet-wearing behavior and were published before December 31, 2021, were included in our study and underwent data extraction. We assessed the quality of the included articles using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist for observational studies. RESULTS: A total of 50 articles were included. Most evidence suggests that helmet usage is more common among drivers (compared to passengers), women, middle-aged adults, those with higher educations, married individuals, license holders, and helmet owners. Moreover, the helmet usage rate is higher on highways and central city roads and during mornings and weekdays. Travelers of longer distances, more frequent users, and riders of motorcycles with larger engines use safety helmets more commonly. Non-helmet-using drivers seem to have acceptable awareness of mandatory helmet laws and knowledge about their protective role against head injuries. Importantly, complaint about helmet discomfort is somehow common among helmet-using drivers. CONCLUSIONS: To enhance helmet usage, policymakers should emphasize the vulnerability of passengers and children to RTIs, and that fatal crashes occur on low-capacity roads and during cruising at low speeds. Monitoring by police should expand to late hours of the day, weekends, and lower capacity and less-trafficked roads. Aiming to enhance the acceptance of other law-abiding behaviors (e.g., wearing seat belts, riding within the speed limits, etc.), especially among youth and young adults, will enhance the prevalence of helmet-wearing behavior among motorcycle riders. Interventions should put their focus on improving the attitudes of riders regarding safety helmets, as there is acceptable knowledge of their benefits.

Perceived stress by mototaxi drivers and its relationship with sociodemographic and occupational characteristics / Estrés percibido por mototaxistas y su relación con características sociodemográficas y ocupacionales / Estresse percebido por mototaxistas e sua relação com características sociodemográficas e ocupacionais

ABSTRACT Objective: To investigate the association of sociodemographic and occupational characteristics with a high level of perceived stress in motorcycle taxi drivers. Method: Cross-sectional study carried out with motorcycle taxi drivers who answered instruments on sociodemographic and occupational variables - Perceived Stress Scale, Job Content Questionnaire and Effort-Reward Imbalance. Descriptive statistics, Pearson's chi-square test and Poisson regression with robust variance were used. Statistical significance was 5%. Results: Of the 800 motorcycle taxi drivers, 46.8% had a high level of perceived stress. In the multivariate analysis, a high level of stress was associated with low control over work (PR=7.76; 95%CI=5.19-11.61), low social support at work (PR=3.87; 95%CI =2.95 5.08), working hours longer than eight hours a day (RP=1.47; 95%CI=1.21-1.78) and monthly income less than or equal to two minimum wages (PR=1.34;95%CI=1.13-2.58). Conclusion: Long working hours, occupational stressors and low income were associated with a high level of perceived stress. Public policies and interventions to minimize occupational stressors are essential.

Resultados: Dos 800 mototaxistas, 46,8% apresentaram alto nível de estresse percebido. Na análise multivariada, o alto nível de estresse foi associado com baixo controle sobre o trabalho (RP=7,76; IC95%=5,19-11,61), baixo suporte social no trabalho (RP=3,87; IC95%=2,95 5,08), jornada de trabalho maior que oito horas por dia (RP=1,47; IC95%=1,21-1,78) e renda mensal menor ou igual a dois salários mínimos (RP=1,34; IC95%=1,13-2,58). Conclusão: Extensa jornada de trabalho, estressores ocupacionais e baixa renda foram associados ao alto nível de estresse percebido. Políticas públicas e intervenções para minimizar estressores ocupacionais são imprescindíveis.

Mortalidade e anos de vida ajustados por incapacidade de motociclistas na América Latina e Caribe na primeira década de segurança viária / Mortality and disability-adjusted life years in motorcyclists in Latin America and the Caribbean during the first decade of action for road safety / Mortalidad y años de vida ajustados por discapacidad de los motociclistas en América Latina y el Caribe en la primera década de seguridad vial

RESUMO Objetivo. Identificar a tendência temporal da mortalidade e dos anos de vida perdidos por morte ou incapacidade (DALY) de homens por acidente motociclístico na América Latina e Caribe no período de 2010 a 2019, utilizando estimativas do estudo Global Burden of Disease (GBD). Métodos. Este estudo ecológico analisou a série temporal pelo modelo de regressão linear segmentada (joinpoint), estimando-se e testando-se a variação percentual anual e a variação percentual anual média, com intervalo de confiança de 95%. Resultados. A grande região da América Latina e Caribe definida pelo GBD ocupou o primeiro lugar global em mortalidade e DALY de motociclistas homens de 15 a 49 anos em 2019. As taxas aumentaram significativamente de 2010 a 2013, havendo redução significativa de ambas após esse período. Durante a década analisada, a sub-região da América Latina Tropical (Brasil e Paraguai) apresentou as maiores taxas de mortalidade e DALY na população em estudo, porém foi a única com redução significativa das mesmas; a sub-região do Caribe (Bermudas, Dominica, Suriname, Guiana, Belize, Bahamas, Porto Rico, Santa Lúcia, República Dominicana, Haiti, São Cristóvão e Névis, Ilhas Virgens/EUA, Granada, Trinidad e Tobago, Barbados, São Vicente e Granadinas, Antígua e Barbuda, Cuba e Jamaica) apresentou aumento significativo de ambas as taxas, enquanto América Latina Andina (Equador, Bolívia e Peru) e América Latina Central (Colômbia, Costa Rica, El Salvador, Guatemala, México, Nicarágua, Panamá, Honduras e Venezuela) permaneceram estáveis. Conclusões. Os dados reforçam a importância das ações de vigilância destinadas à prevenção de acidentes motociclísticos, uma vez que os resultados de queda nas taxas ainda são insuficientes frente à morbimortalidade no trânsito como problema de saúde pública.

ABSTRACT Objective. To identify the temporal trend in mortality and years of life lost to death or disability (DALY) due to motorcycle accidents in males from Latin America and the Caribbean from 2010 to 2019, using estimates produced by the Global Burden of Disease (GBD) study. Method. In this ecological study, the time series was analyzed using a piecewise linear regression model (joinpoint) to estimate and test the annual percent change and the average annual percent change with a 95% confidence interval. Results. The super-region defined by GBD 2019 as Latin America and the Caribbean ranked first globally in mortality and DALY for male motorcyclists aged 15-49 in 2019. Rates increased significantly from 2010 to 2013, with a significant reduction in both after this period. During the analyzed decade, the Tropical Latin America sub-region (Brazil and Paraguay) had the highest mortality and DALY rates in the population of interest; nevertheless, this was the only sub-region achieving a significant reduction in these rates. The Caribbean sub-region (Bermuda, Dominica, Suriname, Guyana, Belize, Bahamas, Puerto Rico, Saint Lucia, Dominican Republic, Haiti, Saint Kitts and Nevis, U.S. Virgin Islands, Grenada, Trinidad and Tobago, Barbados, Saint Vincent and the Grenadines, Antigua and Barbuda, Cuba e Jamaica) showed a significant increase in both rates over the same period, while Andean Latin America (Ecuador, Bolivia and Peru) and Central Latin America (Colombia, Costa Rica, El Salvador, Guatemala, Mexico, Nicaragua, Panama, Honduras, and Venezuela) remained stable. Conclusions. The data underscore the importance of developing surveillance actions aimed at preventing motorcycle accidents, since the observed declining rates are still insufficient to address the morbidity and mortality associated with road accidents as a public health problem.

RESUMEN Objetivo. Determinar la tendencia temporal de la mortalidad y los años de vida perdidos por muerte o ajustados por discapacidad (AVAD) de hombres por accidentes de motocicleta en América Latina y el Caribe en el período 2010-2019, a partir de las estimaciones del estudio de la carga mundial de enfermedades (CME). Métodos. En este estudio ecológico se analizaron las series temporales mediante el modelo de regresión lineal segmentada (joinpoint), con cálculo y comprobación del cambio porcentual anual y del cambio porcentual anual promedio, con un intervalo de confianza del 95%. Resultados. La región de América Latina y el Caribe definida por el estudio de la CME ocupó el primer lugar a nivel mundial en mortalidad y AVAD de motociclistas varones de 15 a 49 años en el 2019. Las tasas tuvieron un notable aumento del 2010 al 2013, y ambas registraron una reducción importante después de ese período. En la década analizada, la subregión de América Latina Tropical (Brasil y Paraguay) presentó las mayores tasas de mortalidad y de AVAD en la población de estudio, pero fue la única con una reducción importante de las mismas. La subregión del Caribe (Antigua y Barbuda, Bahamas, Barbados, Belice, Bermudas, Cuba, Dominica, Granada, Guyana, Haití, Islas Vírgenes de Estados Unidos, Jamaica, Puerto Rico, República Dominicana, Saint Kits y Nevis, San Vicente y las Granadinas, Santa Lucía, Suriname, y Trinidad y Tabago) mostró un aumento importante de ambas tasas, mientras que América Latina Andina (Bolivia, Ecuador y Perú) y América Latina Central (Colombia, Costa Rica, El Salvador, Guatemala, Honduras, México, Nicaragua, Panamá y Venezuela) se mantuvieron estables. Conclusiones. Los datos refuerzan la importancia de las actividades de vigilancia destinadas a prevenir los accidentes de motocicleta, puesto que la reducción observada de las tasas aún es insuficiente para abordar la morbimortalidad por accidentes de tráfico como problema de salud pública.

THE IMPACT OF COVID-19 ON THE PROFILE OF MOTORCYCLE ACCIDENTS ATTENDED AT A TERTIARY HOSPITAL IN CAMPINAS.

Traffic-accidents are a public health problem with repercussions on population morbimortality. Objective: To analyze the impact of the pandemic on the profile of motorcycle accidents assisted at the Tertiary Hospital in 2020. Methods: Cross-sectional, descriptive retrospective study in 2017 and 2020 of 260 medical records of care for motorcycle accidents in the emergency room of the Tertiary Hospital. Statistical analysis of data and their correlations using the chi-square test (p < 0.05). Results: Of the 105 medical records in 2017, 83% are men, mean age 29.8 years, and death rate of 3.90%. Fractures in 98.10%, 64.10% exposed and predominantly the tibia (61.90%). Of the 155 medical records in 2020, 91.61% are men, mean age 31.21 years, and no deaths. Fractures in 94.84%, 37.42% exposed and predominantly the tibia (28.57%). Between 2017 and 2020, Infosiga-SP showed a relevant reduction (p < 0.001) of deaths in the hospital environment (52.46% to 31.91%). Conclusion: The incidence of motorcycle accidents increased, in-hospital deaths dropped, but the epidemiological profile of accidents at the Hospital remained unchanged. Level of Evidence III, Comparative Retrospective Study.

Injuries to Users of Single-Track Vehicles.

INTRODUCTION: Single-track vehicles (including, among others, scooters, bicycles, mopeds, and motorcycles) are becoming increasingly popular means of transport, especially in large cities. A significant disadvantage of single-track vehicles is the low level of protection of users' bodies during road accidents, which causes life-threatening injuries. The aim of this study is to characterize the injuries of users of single-track vehicles. MATERIAL AND METHODS: An analysis of medical documentation of the ambulance service in the region of central Poland covered cases in 2019-2020. Out of 17,446 interventions, a group of 248 road incidents involving single-track vehicles was selected. The data included the scene of the event, the sociodemographic data of the casualties, the injuries suffered, and the clinical diagnoses. Analyses of the correlation of variables with the chi-squared and Spearman's Rho tests were applied. All results were considered significant at p < 0.05. RESULTS: In the analyzed period, trips of men accounted for 83.5% of all of the interventions (n = 207), while trips of women accounted for 16.5% (n = 41). The mean age of the victims was 45.66 years (SD ± 20.45). Taking into account the division of single-track vehicles, individual cases were recorded with the participation of bicycles (n = 183), motorcycles (n = 61), and scooters (n = 4). Taking into account the type of event, the following were distinguished: deductions (n = 62), falls (n = 179), and sickness (n = 7). The most common injuries were to the heads of cyclists (n = 101, which constitutes 55.19% of all injuries), lower limb injuries in motorcyclists (n = 35; 57.38%), and head injuries in scooter users (n = 3; 75%). The locations of sustained injuries significantly correlated with the type of vehicle in the cases of head injuries (p = 0.046), spine/back injuries (p = 0.001), pelvis injuries (p = 0.021), and lower limb injuries (p = 0.001). CONCLUSIONS: The users of single-track vehicles injured in road accidents were more often men than women. The characteristics of the injuries depended on the type of vehicle. The lack of adequate body protection significantly increases the likelihood of death or damage to health. It is advisable to promote safety rules among users of single-track vehicles, with a particular emphasis on the protection of individual parts of the body.

Are the Aetiologies of Traumatic Injuries Changing in Nigeria? Evidence from the Emergency Department of a Referral Hospital in Southwest Nigeria.

Background: Traumatic injuries are a serious public health problem. The burden of these injuries is increasing globally, and there is evidence that the pattern is changing. Objective: The study had two objectives. The first was to determine the aetiology and clinical spectrum of trauma in a teaching hospital. The second was to determine whether these have changed compared with previous reports from the region. Materials and Methods: Between September 2017 and August 2018, data from injured patients who presented consecutively to the accident and emergency department at the Federal Teaching Hospital Ido-Ekiti, Nigeria, were prospectively collected using a trauma data form and analysed. Results: Road traffic crashes (RTCs) caused 75.6% of the injuries, and motorcycle crashes accounted for more injuries than all the other major causes of injuries combined. Compared with previous studies from the same hospital, assault has risen to the second position, whereas falls have fallen to the third position as causes of traumatic injuries. The Injury Severity Scores (ISS) of the patients ranged from 1 to 75, with a mean score of 7.01. The mortality rate was 2.5%. Time to treatment: odds ratio (OR) = 3.25 (1.1-10.0), ISS: OR = 1.172 (1.07-1.28), age: OR = 1.097 (1.013-1.188), and systolic blood pressure: OR=1.07 (1.106-1.025) were the significant predictors of mortality. No patient was transported to the hospital in an ambulance. Conclusion: The pattern of trauma in the subregion is changing as the proportion secondary to RTCs and motorcycle crashes is higher than previously reported studies from the area. The implication of this finding for the prevention of RTCs is discussed.
