Abstract

Background: Mortality from external causes is a major public health issue globally, with significant impacts on both lives and economies. In Brazil, external cause mortality has shown spatiotemporal variations across regions, influenced by social, economic, and demographic factors.

Objective: This study aimed to examine the spatiotemporal dynamics of mortality from external causes in Brazil for 23 years (2000-2022), identifying patterns across regions and demographic groups and assessing the major contributing causes of death.

Methods: This ecological study used data from the Brazilian Mortality Information System (SIM) and used joinpoint regression to analyze temporal trends, Moran I for spatial analysis, and Poisson scanning statistics for spatiotemporal patterns. A total of 3,240,023 deaths were analyzed, with specific attention given to regional and demographic disparities.

Results: The study found that mortality from external causes remained significant, with men and young adults (20-39 years) having the highest rates of death. The main causes of death were assaults (36.61%), transport accidents (26.55%), falls (7.83%), and self-harm (7.43%). Despite an overall decrease in mortality, increases were observed in the North and Northeast regions and among the older adults. High-risk areas were predominantly located in the North, Northeast, and Central-West regions. The mortality trends varied by region, with significant differences in risk across the country.

Conclusions: Although there was a general reduction in mortality from external causes in Brazil, this trend was not uniform across all regions. The North, Northeast, and Central-West regions showed the highest mortality risks, with men and young adults being the most affected demographic groups. These findings emphasize the need for targeted public health interventions that address the regional and demographic disparities in mortality from external causes.

巴西外因死亡的时空趋势：23年生态和基于人口的研究

背景：外因死亡是一个全球性的重大公共卫生问题，对生活和经济都有重大影响。在巴西，受社会、经济和人口因素的影响，外因死亡率在不同区域表现出时空差异。目的：本研究旨在研究巴西23年（2000-2022年）外因死亡率的时空动态，确定不同区域和人口群体的模式，并评估主要的死亡原因。方法：本生态研究利用巴西死亡率信息系统（SIM）的数据，采用联点回归分析时间趋势，Moran I进行空间分析，泊松扫描统计进行时空格局分析。总共分析了3 240 023例死亡，特别注意了区域和人口差异。结果：研究发现，外因造成的死亡率仍然很高，男性和年轻人（20-39岁）的死亡率最高。死亡原因主要为殴打（36.61%）、交通事故（26.55%）、跌倒（7.83%）和自残（7.43%）。尽管死亡率总体下降，但在北部和东北地区以及老年人中观察到死亡率上升。高危区主要分布在北部、东北部和中西部地区。死亡率趋势因地区而异，全国各地的风险差异很大。结论：尽管巴西的外因死亡率普遍下降，但这一趋势在所有地区并不统一。北部、东北部和中西部地区显示出最高的死亡风险，男性和年轻人是受影响最大的人口群体。这些调查结果强调需要有针对性的公共卫生干预措施，以解决区域和人口在外因死亡率方面的差异。
