Incidence of road injuries in Mexico: country report

Road injury burden in Mexico 1990 to 2019: Secondary data analysis from the Global Burden of Disease Study

Road injuries have been a major cause of premature mortality and disability in Mexico. The objective of this paper is to report the findings from the Global Burden of Disease study (GBD-2019) on road injuries in Mexico at a national and subnational scale from 1990 to 2019, and to assess the association between road injury burden and the socio-demographic index. Following the 2019 Global Burden of Disease study road injury mortality, premature mortality, the years lived with disability and disability-adjusted life-years (DALYs) are reported. While the number of deaths from road injuries increased between 1990 and 2019, the age-standardized mortality rates declined. Pedestrian road injuries and motor vehicle road injuries accounted for 8 of every 10 deaths from road injury in 2019. Road injury mortality and DALY rates decreased nationally, but stagnated since 2011. The road injury burden was higher for men in all age groups. Pedestrian and motor vehicle road injuries caused the highest DALY rate in both males and females. There was no significant association between the SDI and the road injury age-standardized DALY rates. This study presents a comprehensive report of road injury burden of disease in Mexico. Mexico continues to have an incomplete, fragmented and poorly enforced legislative framework, with a large diversity between its 32 states. Thus, an integrated legislative and juridical effort is needed to continue reducing the road injury disease burden, which is tailored for specific age groups, vulnerable road users and high-burden areas.

The burden of injuries in Mexico: Secondary data analysis from the Global Burden of Disease Study, 1990 to 2019

IMPORTANCE

Injuries have been a major cause of premature mortality and short-term and long-term disability in Mexico.

OBJECTIVE

To report the findings from the Global Burden of Disease 2019 study on injuries in Mexico at a national and subnational scale from 1990 to 2019.

METHODS

Following the 2019 Global Burden of Disease study we examined injury mortality, premature mortality, years lived with disability and disability-adjusted life-years according to 14 subcategories. We calculated the Pearson correlation coefficient between the injury burden and the socio-demographic index.

RESULTS

While the number of deaths from injuries increased significantly, the changes in the age-standardized mortality rates trended towards declines. Interpersonal violence, road injuries, falls and self-harm accounted for 8 of every 10 deaths from injury in 2019. Injury mortality and the disability-adjusted life-years rates decreased nationally and in most states in the period as a whole, but have increased since 2007. The injury burden was higher for men in all age groups. Interpersonal violence caused the highest disability-adjusted life-years rate in males and road injuries in females. The socio-demographic index increased in all states, while the injury age-standardized disability-adjusted life-years rates between 1990 and 2019 decreased, but there was no statistical association between both indicators.

DISCUSSION AND CONCLUSIONS

This study represents a comprehensive review of injury burden of disease in Mexico. The injury burden decreased, but improved heterogeneously among states. To further reduce the injury burden of disease, it's necessary for federal, state and local governments to prioritize safety promotion and injury prevention programs, infrastructure improvements, legislation, and enforcement at a national and subnational level. Mexico's injury prevention efforts should also be tailored for specific age groups, such as males aged 20-49 years or females in the younger and older age groups, and high-burden areas.

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.

Global Incidence and Mortality Patterns of Pedestrian Road Traffic Injuries by Sociodemographic Index, with Forecasting: Findings from the Global Burden of Diseases, Injuries, and Risk Factors 2017 Study

(1) Background: Pedestrian injuries (PIs) represent a significant proportion of road traffic injuries. Our aim was to investigate the incidence and mortality of PIs in different age groups and sociodemographic index (SDI) categories between 1990 and 2017. (2) Method: Estimates of age-standardized incidence and mortality along with trends of PIs by SDI levels were obtained from the Global Burden of Disease from 1990 to 2017. We also forecasted the trends across all the SDI categories until 2040 using the Statistical Package for the Social Sciences (SPSS Statistics for Windows, version 23.0, Chicago, IL, USA) time series expert modeler. (3) Results: Globally, the incidence of PIs increased by 3.31% (−9.94 to 16.56) in 2017 compared to 1990. Men have higher incidence of PIs than women. Forecasted incidence was 132.02 (127.37 to 136.66) per 100,000 population in 2020, 101.52 (65.99 to 137.05) in 2030, and reduced further to 71.02 (10.62 to 152.65) by 2040. Globally across all SDI categories, there was a decreasing trend in mortality due to PIs with the global estimated percentage reduction of 37.12% (−45.19 to −29.04). (4) Conclusions: The results show that PIs are still a burden for all SDI categories despite some variation. Although incidence and mortality are expected to decrease globally, some SDI categories and specific vulnerable age groups may require particular attention. Further studies addressing incidence and mortality patterns in vulnerable SDI categories are needed.

El estado de las lesiones causadas por el tránsito en México: evidencias para fortalecer la estrategia mexicana de seguridad vial

Mediante la revisión de información secundaria oficial, publicaciones científicas y el análisis de la ENSANut-2012, este trabajo busca proveer una visión integral de la magnitud actual de las lesiones causadas por el tránsito (LCT) en México y analizar críticamente la respuesta social organizada. Las altas tasas de choques, lesiones, muertes y discapacidad atribuidas a este problema de salud pública, representan un elevado costo para la sociedad mexicana, en especial para los hogares. Se discute cómo la respuesta mexicana se ha enfocado a los automovilistas, dejando fuera a usuarios vulnerables de la vía pública y se ha privilegiado la implementación de estrategias poco efectivas. A pesar de que se dispone de legislación para los principales factores de riesgo, se ha descuidado su correcta aplicación. La estrategia mexicana podría fortalecerse implementando estrategias de movilidad seguras, equitativas, saludables y sostenibles para los diferentes actores de la vía pública. A pesar de los avances que se han dado en términos de prevención de LCT, existen aún retos y oportunidades para el país.

Spatial environmental risk factors for pedestrian injury collisions in Ciudad Juárez, Mexico (2008-2009): implications for urban planning

The aim of this study is to examine the spatial distribution of pedestrian injury collisions and analyse the environmental (social and physical) risk factors in Ciudad Juarez, Mexico. More specifically, this study investigates the influence of land use, density, traffic and socio-economic characteristics. This cross sectional study is based on pedestrian injury collision data that were collected by the Municipal Transit Police during 2008-2009. This research presents an analysis of vehicle-pedestrian collisions and their spatial risk determinants using mixed methods that included (1) spatial/geographical information systems (GIS) analysis of pedestrian collision data and (2) ordinary least squares (OLS) regression analysis to explain the density of pedestrian collisions data. In our model, we found a higher probability for pedestrian collisions in census tracts with population and employment density, large concentration of commercial/retail land uses and older people (65 and more). Interventions to alleviate this situation including transportation planning such as decentralisation of municipal transport system, investment in road infrastructure - density of traffic lights, pedestrian crossing, road design, improves lane demarcation. Besides, land use planning interventions should be implemented in commercial/retail areas, in particular separating pedestrian and vehicular spaces.

National burden of road traffic injuries in Argentina

More than 1.2 million people die and as many as 50 million people are injured or disabled due to road traffic injuries (RTIs) every year worldwide. The lack of reliable data hinders efforts to describe the characteristics of the issue and prioritise prevention activities. The objective was to provide a snapshot of fatal and non-fatal RTI in Argentina. We used the methodology proposed by the Global Burden of Disease Injury Expert group. External causes of deaths with unknown codes were proportionately redistributed over the known categories. In 2007 in Argentina, we estimated 5915 RTI deaths, compared with 3983 RTI deaths reported previously by the Ministry of Health, accounting for 1931 additional cases. The highest number of deaths occurred in young men (15-29 years old), although the highest RTI death rates were in the age group of 55 years and older. Four-wheeled vehicle occupants were the most common road user type killed (59.1%); vulnerable road users represented one third (29.5%) of deaths and 64% of non-fatal RTI. The national and regional estimates of RTI in Argentina should help policy makers and public-health researchers to understand the importance of RTI prevention and design specific interventions to further reduce these preventable deaths and injuries.
