This study aimed to investigate patterns of mortality by road transport injury (RTI) in Brazilian municipalities, focused on deaths of motorcyclists, between 2000 and 2018, and their relation with population size and economic status.
This was an ecological epidemiological study with a descriptive and analytical nature.
The age-standardized RTI mortality rates were calculated for the Brazilian municipalities, referring to the 3-year periods of 2000/2002 (T1), 2009/2011 (T2), and 2016/2018 (T3). The rates were stratified according to macroregion and population size and were compared in terms of percentage variation from one 3-year period to another. The Moran Global and Local indices were used in the spatial point-pattern analysis of the rates. To verify the association with the gross domestic product (GDP) per capita, the Spearman correlation coefficient was applied.
A decline in RTI mortality rates was found between 2000 and 2018, with the most significant declines observed in municipalities from the South and Southeast regions of Brazil. However, increases were observed among motorcyclists. Clusters of municipalities were detected, which presented high mortality rates among the motorcyclists in the Northeast region and in some states of the North and Midwest regions. The mortality rates showed a negative correlation with the GDP per capita of the Brazilian municipalities.
Although there were decreases in RTI mortality rates between 1990 and 2018, there was a significant increase in deaths among motorcyclists, especially in the Northeast, North, and Midwest regions of the country. Such differences can be explained by unequal growth in the size of the motorcycle fleet in those regions, by less law enforcement capability, and by the implementation of educational actions.
本研究旨在调查巴西各城市因道路交通伤害（RTI）导致的死亡率模式，重点关注摩托车手的死亡情况，时间范围为 2000 年至 2018 年，并探讨其与人口规模和经济状况的关系。
这是一项具有描述性和分析性的生态流行病学研究。
计算了巴西各城市的年龄标准化 RTI 死亡率，涉及 2000/2002 年（T1）、2009/2011 年（T2）和 2016/2018 年（T3）这三个 3 年周期。根据大区域和人口规模对死亡率进行分层，并比较了各周期之间的百分比变化。采用 Moran 全局和局部指数对死亡率的空间点模式进行分析。为了验证与人均国内生产总值（GDP）的关系，应用了斯皮尔曼相关系数。
发现 2000 年至 2018 年期间，RTI 死亡率呈下降趋势，其中巴西南部和东南部地区的下降幅度最大。然而，摩托车手的死亡率却有所上升。检测到了一些呈现高死亡率的摩托车手的集群，这些集群主要分布在巴西东北部以及北部和中西部的一些州。死亡率与巴西各城市的人均 GDP 呈负相关。
尽管 1990 年至 2018 年期间 RTI 死亡率有所下降，但摩托车手的死亡率却显著上升，尤其是在该国的东北部、北部和中西部地区。这些差异可以通过这些地区摩托车保有量的不均衡增长、执法能力较弱以及教育措施的实施来解释。
