OBJETIVO: Estimar la prevalencia de lesiones no intencionales (LNI) y sus consecuencias no fatales en población mexicana. Material y métodos. Estudio transversal con la Encuesta Nacional de Salud y Nutrición Continua 2022 (Ensanut Continua 2022), diseñada con muestreo probabilístico, polietápico y estratificado. Se estimó la prevalencia de LNI, por grupo de edad, sexo, región, estrato de residencia e índice de bienestar. RESULTADOS: La prevalencia de LNI fue 5.74% (IC95%: 5.31,6.21); 30.5% reportó consecuencias permanentes en salud y 62% requirió atención en servicios de salud públicos. Las regiones Península, Pacífico-Sur y Pacífico-Centro presentaron prevalencias más altas (6.69, 6.43 y 6.36% respectivamente), en hombres (6.8%) y en población de 10-19 años (6.51%). Las caídas fueron la causa más frecuente con 57.6%; vía pública (39.5%) y hogar (29%) los principales sitios de ocurrencia. CONCLUSIONES: Las LNI no fatales afectan de manera diferenciada a hombres y población joven; caídas y lesiones de tránsito causan importante demanda en servicios de salud y discapacidad.

[Indicators to measure the performance of emergency trauma care]. / Principales indicadores para medir el desempeño de la atención de emergencias traumatológicas.

The objective of this paper was to identify the main indicators used to measure the performance in emergency trauma care. A literature review was carried out in the electronic databases: PubMEd, LILACS and Epistemónikos, including publications between January 2011 and December 31, 2021, in Spanish, English and Portuguese. A total of 962 publications were identified. When reviewing the full text, 48 articles were included. The indicators were classified in the dimensions of process and results. 100 different indicators were identified to analyze the performance of emergency trauma care. 71% were process indicators, including service time and triage. In the results dimension 29 indicators were identified; mortality was the indicator most analyzed as well as length of stay. Six indicators on the disability of injured people and 14 indicators related to satisfaction were identified, the most frequent being complaints. Various indicators have been used to assess the performance of emergency trauma care. In the results dimension, the indicators related to satisfaction and disability after injuries have been little explored. Decision-makers and those responsible for emergency care must promote performance evaluation exercises to learn about their current situation using appropriate and sensitive indicators with the available data.

Se identificaron 962 publicaciones. Tras revisar el texto completo, 48 artículos fueron incluidos. Los indicadores se clasificaron en las dimensiones de proceso y resultado. Se identificaron 100 diferentes indicadores para analizar el desempeño de la atención de emergencias traumatológicas. 71% fueron indicadores de proceso, entre ellos el tiempo de atención y el triaje. En la dimensión de resultados se identificaron 29 indicadores; la mortalidad fue el indicador mayormente analizado así como el periodo de estancia hospitalaria. Se identificaron seis indicadores sobre la discapacidad de las personas lesionadas y 14 indicadores relacionados con la satisfacción, el más frecuente fue quejas. Diversos indicadores han sido utilizados para evaluar el desempeño de la atención de emergencias traumatológicas. En la dimensión de resultados, los indicadores relacionados con la satisfacción y discapacidad han sido poco explorados. Los responsables de la atención de emergencias traumatológicas deben impulsar ejercicios de evaluación del desempeño para conocer su situación actual a través de indicadores sensibles y acordes con los datos disponibles.

Impact of accidental and intentional injuries in Mexico. Findings of the Global Burden of Disease study for 1990 and 2021.

BACKGROUND: Previous analyses on the burden of disease in Mexico identified that injuries differentially affect young people, males and working-age people. OBJECTIVE: To analyze the burden of disease due to intentional and unintentional injuries in Mexico during 1990 and 2021, at the national and state levels. MATERIAL AND METHODS: The results of the Global Burden of Disease study for the 1990-2021 period were used to describe the burden of disease attributed to injuries in Mexico. The life years lost (YLL) due to premature mortality, years lived with disability (YLD) and disability-adjusted life years (DALY) were analyzed. RESULTS: The burden of disease related to intentional injuries has increased, as also have YLDs and DALYs associated with unintentional injuries. Men continue to have higher mortality and DALY rates compared to women. Interpersonal violence and suicide have steadily increased. The analysis by state showed patterns with important variations. CONCLUSIONS: Injuries generate catastrophic consequences in terms of mortality and disability in Mexico. It is necessary to promote and strengthen programs and policies in order to improve the data system and injury prevention.

ANTECEDENTES: Análisis previos sobre la carga de la enfermedad en México identificaron que las lesiones afectan de manera diferenciada a hombres, personas jóvenes y en edad productiva. OBJETIVO: Analizar la carga de la enfermedad por lesiones intencionales y no intencionales en México durante 1990 y 2021 en los ámbitos nacional y estatal. MATERIAL Y MÉTODOS: Se utilizaron los resultados del Global Burden of Disease respecto al período 1990-2021 para describir la carga de la enfermedad por las principales causas de lesiones en México; se analizaron los años perdidos por muerte prematura (APMP), los años vividos con discapacidad (AVD) y los años de vida saludable perdidos (AVISA). RESULTADOS: La carga de la enfermedad relacionada con lesiones intencionales se ha incrementado, al igual que los AVD y AVISA por lesiones no intencionales. Los hombres continúan presentando tasas de mortalidad y AVISA más altas comparados con las mujeres. La violencia interpersonal y el suicidio se han incrementado de manera sostenida El análisis por estados mostró patrones con variaciones importantes. CONCLUSIONES: Las lesiones generan consecuencias catastróficas en términos de mortalidad y discapacidad en México. Es indispensable impulsar y reforzar los programas y políticas para mejorar el sistema de datos y la prevención de lesiones.

The political and social contexts of global road safety: challenges for the next decade.

The goal of this Series paper is to show how road safety has evolved as a global public health issue over the past two decades and to discuss the political and economic dynamics that led to this change. Specifically, the key stakeholders, influences, networks, issue framing, actor power, and synergistic interactions that have contributed to how road safety has evolved as a global public health issue will be discussed. In doing so, we capture the important chronology of events and discuss a set of challenges that highlight the complexity of road safety. We posit that the global road safety community needs to re-evaluate its role and strategy for the next decade and focus more on implementation and country action to achieve reductions in road traffic injuries. We call for an open and inclusive process to ensure that such a reflection occurs before the end of the current decade.

Governance and injury prevention.

Urban governance implies that state authorities and other actors (including private and social sectors) work together with authentic community participation as needed to meet the challenges to achieve urban health. In this context, addressing the problem of injury is critical. In urban space, injuries can occur for various external causes (falls, burns, even interpersonal violence, etc). This paper includes a discussion and analysis of governance mechanisms on urban areas, in terms of the implementation of the safe system approach which has been proposed as the best preventive strategy, to assure road safety, mostly at urban spaces, for injury prevention. The existence of governance mechanisms needs to be considered as a primary issue to be included on injury research to evaluate the implementation for preventive programmes on the injury field in general, especially those occurred at urban spaces.

Impact of Mexican Road Safety Strategies implemented in the context of the UN's Decade of Action.

OBJECTIVE: To evaluate advancements in the prevention of road traffic injuries (RTI) in Mexico in the context of the United Nation's Decade of Action for Road Safety. METHODS: An analysis of the trend and age-period-cohort effects of RTI mortality from 1999 to 2018 was conducted. Mortality figures were age-standardized using the direct method and population estimates of 2018 as the standard. To evaluate whether advancements might be attributed to higher levels of death misclassification, we conducted sensitive analysis using multiple imputation to redistributed deaths allocated to non-specific ICD-10 codes. Non-fatal RTI from four nationally representative health surveys (2000, 2006, 2012 and 2018) were analyzed. FINDINGS: Implementation of Mexico's National Road Safety Strategy 2011-2020 was associated with an average annual percentage change reduction in the age-standardized RTI mortality rate of 1.3% (95%-CI: -1.8,-0.9). Reductions are more evident in pedestrians and four + wheelers (-6.7% and -5.3%, respectively, from 2011 to 2018); mortality trend in motorcyclists increased from 1999 to 2018 an average of 12.8% annually (95%-CI: 9.9, 15.9). Potential underestimation of mortality due to death misclassification decreased from 22.7% in 1999 to 16.4% in 2018; sensitive analysis showed that reductions might not be attributed to death misclassification. Non-fatal injuries decreased in four + wheelers but increased in motorcyclists. The number of individuals suffering permanent consequences from RTI increased. CONCLUSIONS: Results showed some potential gains of Mexico's road safety strategies: RTI in four + wheelers decreased. Efforts should be put in place urgently to prevent the growing number of RTI in motorcyclists.

Unintentional injuries in Mexico, 1990-2017: findings from the Global Burden of Disease Study 2017.

BACKGROUND: To date, the burden of injury in Mexico has not been comprehensively assessed using recent advances in population health research, including those in the Global Burden of Disease Study 2017 (GBD 2017). METHODS: We used GBD 2017 for burden of unintentional injury estimates, including transport injuries, for Mexico and each state in Mexico from 1990 to 2017. We examined subnational variation, age patterns, sex differences and time trends for all injury burden metrics. RESULTS: Unintentional injury deaths in Mexico decreased from 45 363 deaths (44 662 to 46 038) in 1990 to 42 702 (41 439 to 43 745) in 2017, while age-standardised mortality rates decreased from 65.2 (64.4 to 66.1) in 1990 to 35.1 (34.1 to 36.0) per 100 000 in 2017. In terms of non-fatal outcomes, there were 3 120 211 (2 879 993 to 3 377 945) new injury cases in 1990, which increased to 5 234 214 (4 812 615 to 5 701 669) new cases of injury in 2017. We estimated 2 761 957 (2 676 267 to 2 859 777) disability-adjusted life years (DALYs) due to injuries in Mexico in 1990 compared with 2 376 952 (2 224 588 to 2 551 004) DALYs in 2017. We found subnational variation in health loss across Mexico's states, including concentrated burden in Tabasco, Chihuahua and Zacatecas. CONCLUSIONS: In Mexico, from 1990 to 2017, mortality due to unintentional injuries has decreased, while non-fatal incident cases have increased. However, unintentional injuries continue to cause considerable mortality and morbidity, with patterns that vary by state, age, sex and year. Future research should focus on targeted interventions to decrease injury burden in high-risk populations.

[Non-fatal unintentional injuries in Mexican population: prevalence and associated factors. Ensanut 2018-19]. / Accidentes no fatales en población mexicana, prevalencia y factores asociados. Ensanut 2018-19.

OBJECTIVE: To estimate the prevalence of non-fatal uninten-tional injuries in Mexican population and to analyze individual, environmental and household factors associated with its occurrence. MATERIALS AND METHODS: A cross-sectional study, analyzed the prevalence of unintentional injuries from Encuesta Nacional de Salud y Nutrición (Ensanut 2018-19), which is a nationally representative health survey designed with a probability, stratified and cluster sampling, in three stages. Association with variables of interest was explored using logistic regression analysis. RESULTS: Prevalence of non-fatal unintentional injuries was 4.5% (IC95%: 4.2-4.7), equivalent to 5.6 million people per year. Of them, 22.3% or 1.2 million suffered permanent consequences. Probability of having unintentional injuries was higher in the North and Center regions, as in Mexico City-State of Mexico; in males from 0 to 59 and females of 60 or more years of age, in people living with disabilities and those who self-reported depres-sion symptoms. CONCLUSIONS: Strengthening unintentional injury prevention is necessary and urgent, especially within vulnerable groups of population.

Desarrollo de la capacidad para la regulación en salud en México.

La Academia Nacional de Medicina es un espacio esencial para discutir la ciencia de la regulación en salud y posicionar su impacto en la salud y la economía. Enmarcada dentro de la función rectora de la autoridad sanitaria, la regulación en salud es la acción de proteger a la población de los peligros sanitarios involuntarios contra los cuales el individuo no puede protegerse; es una función esencial de la salud pública, componente institucional del sistema de salud y, por ende, vinculada a sus reformas y a la cobertura universal. La regulación tiene sustento en un cuerpo teórico epidemiológico, organizacional, legal, sociológico y económico. Tiene un cuerpo metodológico que sustenta su proceso en el análisis de riesgos y se traduce en normas, implementaciones, cumplimiento, monitoreo y evaluación de la regulación. Tiene una arquitectura profesional, financiera, organizacional, legal y de gobernanza. Dada su acción universal tiene un impacto generalizado en la población y un sustancial efecto económico, influyendo en al menos 17 % del comercio internacional regional. La salud a través de sus autoridades regulatorias debe ser parte del dialogo comercial internacional.The National Academy of Medicine is an essential space to discuss regulatory science in health, and to position its impact on health and economy. Framed within the stewardship role of the health authority, health regulation is the action of protecting the population against involuntary health hazards against which the individual cannot protect him/herself. It is an essential function of public health, an institutional component of the health system and, therefore, linked to its reforms and to universal coverage. Regulation has its support on an epidemiological, organizational, legal, sociological and economic theoretical body. It has a methodological body that supports its regulatory process based on risk analysis and that is translated into regulations, implementations, compliance, monitoring and evaluation of the regulation. It has a professional, financial, organizational, legal and governance architecture. Given its universal action, it has a widespread impact on the population and a substantial economic effect, influencing on at least 17% of regional international trade. Health through its regulatory authorities should be an early part of international trade discussions.

Advances in Mexico in the middle of the Decade of Action for Road Safety 2011-2020.

OBJECTIVE: To analyze the progress towards the accomplishment of the expected goal in the middle of the Decade of Action for Road Safety 2011-2020 in Mexico and its states. METHODS: This is a secondary analysis of road traffic deaths in Mexico between 1999 and 2015. We projected the trend for the period 2011-2020 using a time series analysis (autoregressive integrated moving average models). We used the value of the Aikaike Information Criterion to determine the best model for the national level and its 32 states. RESULTS: Mexico is progressing, approaching the proposed goal, which translates into 10,856 potentially prevented deaths in the five-year period from 2011 to 2015. This was due to a decrease in the number of deaths of motor vehicle occupants, as the deaths of pedestrians and motorcyclists were higher than expected. At least one third of the states had values below their goal; although the mortality rate remains unacceptably high in five of them. We identified four states with more deaths than those originally projected and other states with an increasing trend; thus, both cases need to strengthen their prevention actions. CONCLUSIONS: The analysis can allow us to see the progress of the country in the middle of the Decade of Action, as well as identify the challenges in the prevention of traffic injuries in vulnerable users. It contributes with elements that provide a basis for a need to rethink both the national goal and the goal of the different states.

Estimating the drink driving attributable fraction of road traffic deaths in Mexico.

AIM: To estimate the Drink Driving Attributable Fraction (DDAF) of road traffic injury mortality in car occupants in Mexico during 2010-13. DESIGN: A case-control study was conducted to examine the presence of alcohol in analysed body fluids of car occupants killed in fatal crashes (cases) compared with car drivers tested in alcohol-testing checkpoints who were not involved in a fatal collision (controls). Two data sets were used for the period 2010-13: the forensic module of the Epidemiological Surveillance System on Addictions that included car occupants killed in a collision (cases) and a data set from alcohol-testing at police checkpoints available for matching municipalities (controls). SETTING: Mexico. PARTICIPANTS: The analysed study sample included 1718 car occupants killed in a traffic collision and 80 656 drivers tested at alcohol police checkpoints, all from 10 municipalities. MEASUREMENTS: Unadjusted and adjusted odds ratios (OR) of presence of alcohol in body fluids were obtained stratified by sex and age groups and the interaction with these two variables were assessed. The ORs were used to calculate the DDAF. FINDINGS: It was estimated that 19.5% of car occupants' deaths due to road traffic injuries were attributable to alcohol consumption [95% confidence interval (CI) = 19.1-19.9]. The adjusted OR of presence of alcohol was 6.84 (95% CI = 6.06-7.71) overall. For males it was 7.21 (95% CI = 6.35-8.18) and for females it was 4.45 (95% CI = 3.01-6.60). The ORs were similar across younger age bands (10-19 years: 9.61, 95% CI = 6.72-13.73; 20-29 years: 7.70, 95% CI = 6.28-9.4; and 30-49 years: 7.21, 95% CI = 5.98-8.70); and lower but still elevated among older people (50+ years: 3.19, 95% CI = 2.19-4.65). CONCLUSIONS: An estimated 19.5% of car occupant deaths in Mexico may have been caused by alcohol in 2010-13.

RESUMEN OBJETIVO Analizar el avance de la meta esperada a mitad del Decenio de Acción para la Seguridad Vial 2011-2020 en México y sus entidades federativas. MÉTODOS Análisis secundario de las muertes por accidentes de tránsito en México para el 1999-2015. Se proyectó la tendencia para el periodo 2011-2020 utilizando análisis de series de tiempo (modelos autorregresivos integrados de medias móviles). Se utilizó el valor del Criterio de Información de Aikaike para determinar el mejor modelo para el nivel nacional y sus 32 entidades federativas. RESULTADOS México va avanzando cercano a la meta propuesta, lo que se ha traducido en 10,856 defunciones potencialmente prevenidas en el quinquenio 2011 a 2015. Esto ha sido a expensas de una disminución en el número de muertes de ocupantes de vehículos de motor; ya que las muertes en peatones y motociclistas han ido por arriba de lo que se esperaba. Al menos una tercera parte de las entidades federativas tuvo el número de defunciones por debajo de su meta; aunque en cinco de ellas la tasa de mortalidad continúa inaceptablemente alta. Se identificaron cuatro entidades con más muertes que las proyectadas originalmente y otras con tendencia al incremento donde se requiere, para ambos casos, fortalecer las acciones de prevención. CONCLUSIONES El análisis realizado permite observar los avances del país a mitad del Decenio de Acción, así como identificar los retos en materia de prevención de lesiones causadas por el tránsito en usuarios vulnerables. Aporta elementos para soportar la necesidad de replantear tanto la meta nacional como la de las distintas entidades federativas.

[Legislation on road safety in Mexico: a subnational analysisLegislação de segurança viária no México: uma análise subnacional]. / Legislación sobre seguridad vial en México: un análisis subnacional.

OBJECTIVE: Study federal and state regulations to determine to what extent road safety recommendations are followed with regard to different risk factors and protective factors. METHODS: A descriptive analysis was made of the legal frameworks for road safety at the federal level and in the 32 Mexican states, identifying those that had regulations respecting the main risk factors (speeding, drinking and driving, and cellphone use while driving) and the main protective factors against road injuries (helmet use, seat belt use, and use of child restraint systems). The adequacy of these regulations was analyzed on the basis of Pan American Health Organization/World Health Organization (PAHO/WHO) recommendations. The types of sanctions prescribed in these regulations are also described. RESULTS: Slightly less than 10% of the entities studied had specific regulations respecting the six protective and risk factors considered. It was noted that "drinking and driving" and "helmet use" are, respectively, the risk factor and protective factor most commonly included in state laws. Adequate regulations were found in only two states: Zacatecas (regarding speeding) and Jalisco (seat belts, child restraint systems, and helmet use). Monetary fines are the most frequently applied sanction. CONCLUSIONS: It is a key priority to promote comprehensive laws with provisions that adequately address technical and scientific criteria for protection and prevention, as well as appropriate mechanisms for monitoring, regulation, and sanctions.

OBJETIVO: Realizar un diagnóstico de la normativa federal y estatal para determinar en qué medida se siguen las recomendaciones en materia de seguridad vial para distintos factores de riesgo y factores protectores. MÉTODOS: Se realizó un análisis descriptivo de los distintos ordenamientos jurídicos federales y de las 32 entidades federativas de México en el tema de la seguridad vial. Se identificaron aquellas que tenían disposiciones sobre los principales factores de riesgo (exceso de velocidad, alcohol y conducción, uso de celular al conducir) y protectores de lesiones causadas por el tránsito (uso de casco, uso de cinturón de seguridad y uso de sistemas de retención infantil) y se analizó si estas eran adecuadas, con base en las recomendaciones de la Organización Mundial de la Salud/Organización Panamericana de la Salud (OMS/OPS). Además, se describen los tipos de sanciones empleados en dichos ordenamientos. RESULTADOS: Poco menos de 10% de las entidades analizadas cuentan con normatividad específica para los seis factores protectores y de riesgo analizados. Se observó que el factor de riesgo "alcohol y conducción" y el factor protector "uso de casco" son los que están más considerados en las leyes estatales. Solo en dos entidades federativas (estados) la normatividad es adecuada: en Zacatecas (en el tema de velocidad) y en Jalisco (cinturón de seguridad, sistemas de retención infantil y uso de casco). La sanción aplicada con mayor frecuencia es la multa económica. CONCLUSIONES: Es fundamental y prioritario impulsar leyes integrales que contemplen disposiciones adecuadas que aborden criterios técnicos y científicos de protección y prevención, así como los mecanismos apropiados para vigilar, regular y sancionar.

RESUMO Objetivo Realizar um diagnóstico da regulamentação federal e estadual para determinar em que medida são cumpridas as recomendações de segurança viária com relação a diferentes fatores de risco e de proteção. Métodos Foi conduzida uma análise descritiva das disposições jurídicas federais e das 32 entidades federativas do México em segurança viária. Foram identificadas as entidades que dispunham de regulamentação legal sobre os principais fatores de risco (excesso de velocidade, consumo de álcool antes de dirigir, uso de celular ao dirigir) e fatores de proteção para acidentes de trânsito (uso de capacete, cinto de segurança e dispositivos de retenção infantil) e analisada sua adequação segundo as recomendações da Organização Mundial da Saúde/Organização Pan-Americana da Saúde (OMS/OPAS). Além disso, são descritos os tipos de sanções aplicadas nestas disposições. Resultados Quase 10% das entidades analisadas dispõem de legislação específica para os seis fatores de risco e de proteção analisados. Observou-se que o fator de risco "consumo de álcool antes de dirigir" e o fator de proteção "uso de capacete" são os mais frequentemente incluídos na legislação estadual. A legislação é adequada em apenas duas entidades federativas (estados): Zacatecas (velocidade de condução) e Jalisco (uso de cinto de segurança, dispositivos de retenção infantil e capacete). A sanção aplicada com maior frequência é a multa. Conclusões É fundamental e prioritário promover uma legislação abrangente contendo disposições adequadas que abordem critérios técnicos e científicos de proteção e prevenção bem como mecanismos apropriados de monitoramento, regulação e cumprimento da legislação.

[Underestimation of mortality caused by traffic in Mexico: an analysis at the subnational level]. / Subestimación de la mortalidad causada por el tránsito en México: análisis subnacional.

OBJECTIVE: To estimate the potential underestimation of mortality from traffic injuries at the subnational level in Mexico for a period of 15 years and to identify social and economic variables at the state level that could potentially be associated with the quality of statistical classification of deaths. MATERIALS AND METHODS: Secondary analysis of validated mortality databases for the period 1999-2013 was conducted. Using multiple imputation models, registries that could potentially be attributed to road traffic deaths were estimated and the potential underestimation of mortality due to this external cause was quantified. A simple correlation analysis was carried out. RESULTS: The potential underestimation of deaths from traffic injuries during the period was 18.85% at the national level, with significant variations by state. From the data analyzed, there was no statistical evidence of any association of the percentage of road traffic deaths underestimation with the variables analyzed. CONCLUSIONS: Performance in terms of mortality classification is different at the state level in Mexico. This information is useful for targeting interventions to improve the recording of deaths in the country.

Subestimación de la mortalidad causada por el tránsito en México: análisis subnacional / Underestimation of mortality caused by traffic in Mexico: an analysis at the subnational level

Resumen: Objetivo: Estimar la potencial subestimación de la mortalidad por lesiones de tránsito en las entidades federativas de México para un periodo de 15 años. Se buscó identificar variables sociales y económicas de cada entidad federativa que pudieran estar potencialmente asociadas con la calidad de la clasificación estadística de las defunciones. Material y métodos: Análisis secundario de bases de mortalidad, periodo 1999-2013. Mediante modelos de imputación múltiple, se identificaron los registros que pudieran ser muertes atribuidas al tránsito y se realizó un análisis de correlación simple. Resultados: La subestimación de defunciones por lesiones de tránsito durante el periodo fue de 18.85%, con importantes variaciones por entidad federativa. No hubo evidencia de que existiera asociación de alguna variable con el porcentaje de subestimación de la mortalidad. Conclusiones: La clasificación de la mortalidad es diferente en las entidades federativas. Esta información es de gran utilidad para focalizar intervenciones que permitan mejorar el registro de las defunciones en el país.

The global burden of injury: incidence, mortality, disability-adjusted life years and time trends from the Global Burden of Disease study 2013.

BACKGROUND: The Global Burden of Diseases (GBD), Injuries, and Risk Factors study used the disability-adjusted life year (DALY) to quantify the burden of diseases, injuries, and risk factors. This paper provides an overview of injury estimates from the 2013 update of GBD, with detailed information on incidence, mortality, DALYs and rates of change from 1990 to 2013 for 26 causes of injury, globally, by region and by country. METHODS: Injury mortality was estimated using the extensive GBD mortality database, corrections for ill-defined cause of death and the cause of death ensemble modelling tool. Morbidity estimation was based on inpatient and outpatient data sets, 26 cause-of-injury and 47 nature-of-injury categories, and seven follow-up studies with patient-reported long-term outcome measures. RESULTS: In 2013, 973 million (uncertainty interval (UI) 942 to 993) people sustained injuries that warranted some type of healthcare and 4.8 million (UI 4.5 to 5.1) people died from injuries. Between 1990 and 2013 the global age-standardised injury DALY rate decreased by 31% (UI 26% to 35%). The rate of decline in DALY rates was significant for 22 cause-of-injury categories, including all the major injuries. CONCLUSIONS: Injuries continue to be an important cause of morbidity and mortality in the developed and developing world. The decline in rates for almost all injuries is so prominent that it warrants a general statement that the world is becoming a safer place to live in. However, the patterns vary widely by cause, age, sex, region and time and there are still large improvements that need to be made.

Legislación sobre seguridad vial en México: un análisis subnacional / Legislation on road safety in Mexico: a subnational analysis / Legislação de segurança viária no México: uma análise subnacional

Objetivo. Realizar un diagnóstico de la normativa federal y estatal para determinar en qué medida se siguen las recomendaciones en materia de seguridad vial para distintos factores de riesgo y factores protectores. Métodos. Se realizó un análisis descriptivo de los distintos ordenamientos jurídicos federales y de las 32 entidades federativas de México en el tema de la seguridad vial. Se identificaron aquellas que tenían disposiciones sobre los principales factores de riesgo (exceso de velocidad, alcohol y conducción, uso de celular al conducir) y protectores de lesiones causadas por el tránsito (uso de casco, uso de cinturón de seguridad y uso de sistemas de retención infantil) y se analizó si estas eran adecuadas, con base en las recomendaciones de la Organización Mundial de la Salud/Organización Panamericana de la Salud (OMS/OPS). Además, se describen los tipos de sanciones empleados en dichos ordenamientos. Resultados. Poco menos de 10% de las entidades analizadas cuentan con normatividad específica para los seis factores protectores y de riesgo analizados. Se observó que el factor de riesgo “alcohol y conducción” y el factor protector “uso de casco” son los que están más considerados en las leyes estatales. Solo en dos entidades federativas (estados) la normatividad es adecuada: en Zacatecas (en el tema de velocidad) y en Jalisco (cinturón de seguridad, sistemas de retención infantil y uso de casco). La sanción aplicada con mayor frecuencia es la multa económica. Conclusiones. Es fundamental y prioritario impulsar leyes integrales que contemplen disposiciones adecuadas que aborden criterios técnicos y científicos de protección y prevención, así como los mecanismos apropiados para vigilar, regular y sancionar.

Objective. Study federal and state regulations to determine to what extent road safety recommendations are followed with regard to different risk factors and protective factors. Methods. A descriptive analysis was made of the legal frameworks for road safety at the federal level and in the 32 Mexican states, identifying those that had regulations respecting the main risk factors (speeding, drinking and driving, and cellphone use while driving) and the main protective factors against road injuries (helmet use, seat belt use, and use of child restraint systems). The adequacy of these regulations was analyzed on the basis of Pan American Health Organization/World Health Organization (PAHO/WHO) recommendations. The types of sanctions prescribed in these regulations are also described. Results. Slightly less than 10% of the entities studied had specific regulations respecting the six protective and risk factors considered. It was noted that “drinking and driving” and “helmet use” are, respectively, the risk factor and protective factor most commonly included in state laws. Adequate regulations were found in only two states: Zacatecas (regarding speeding) and Jalisco (seat belts, child restraint systems, and helmet use). Monetary fines are the most frequently applied sanction. Conclusions. It is a key priority to promote comprehensive laws with provisions that adequately address technical and scientific criteria for protection and prevention, as well as appropriate mechanisms for monitoring, regulation, and sanctions.

Objetivo. Realizar um diagnóstico da regulamentação federal e estadual para determinar em que medida são cumpridas as recomendações de segurança viária com relação a diferentes fatores de risco e de proteção. Métodos. Foi conduzida uma análise descritiva das disposições jurídicas federais e das 32 entidades federativas do México em segurança viária. Foram identificadas as entidades que dispunham de regulamentação legal sobre os principais fatores de risco (excesso de velocidade, consumo de álcool antes de dirigir, uso de celular ao dirigir) e fatores de proteção para acidentes de trânsito (uso de capacete, cinto de segurança e dispositivos de retenção infantil) e analisada sua adequação segundo as recomendações da Organização Mundial da Saúde/Organização Pan-Americana da Saúde (OMS/OPAS). Além disso, são descritos os tipos de sanções aplicadas nestas disposições. Resultados. Quase 10% das entidades analisadas dispõem de legislação específica para os seis fatores de risco e de proteção analisados. Observou-se que o fator de risco “consumo de álcool antes de dirigir” e o fator de proteção “uso de capacete” são os mais frequentemente incluídos na legislação estadual. A legislação é adequada em apenas duas entidades federativas (estados): Zacatecas (velocidade de condução) e Jalisco (uso de cinto de segurança, dispositivos de retenção infantil e capacete). A sanção aplicada com maior frequência é a multa. Conclusões. É fundamental e prioritário promover uma legislação abrangente contendo disposições adequadas que abordem critérios técnicos e científicos de proteção e prevenção bem como mecanismos apropriados de monitoramento, regulação e cumprimento da legislação.

The prevalence of motorcycle helmet use from serial observations in three Mexican cities.

Motorcycle use as a functional and recreational means of transportation is increasing in Mexico; the associated mortality rate has also increased. Appropriate helmet use can reduce a motorcyclist's risk of death or serious injury. This study quantified the prevalence of motorcycle helmet use in three Mexican cities (Cuernavaca, Guadalajara-Zapopan, and León) within the context of several ongoing road safety initiatives. Four rounds of roadside observations were conducted between November 2010 and April 2012. The overall prevalence of helmet use was 73.8% among all users; helmet use was much lower among females (55.3%). Drivers tended to use helmets more frequently than passengers (76.3% vs. 51.6%). The prevalence was higher in León (85.9%, 95% CI = 84.8-87.0) than Cuernavaca (71.5%, 95% CI = 69.3-73.6) and Guadalajara-Zapopan (62.7%, 95% CI = 61.1-64.2). Helmet use decreased in León (p = 0.003) but increased in Guadalajara-Zapopan (p = 0.000) during this period. Motorcycle helmet use could be improved in all three cities. Since motorcycle use is increasing, interventions targeting motorcycle users and greater enforcement of helmet use are necessary to reduce crashes and non-fatal and fatal injuries.
