Injury is one of the main causes of death and disability in the world. This study was designed to determine the trend of mortality rate and years of life lost (YLLs) due to unintentional injuries in children in southern Iran.
In this cross-sectional study, we extracted all death reports due to unintentional injuries based on age, gender and the year of death based on International Classification of Diseases (ICD-10)from the Electronic Death Registration System. The YLL analysis due to premature death related to unintentional injuries was executed by the 2015 YLL template from the WHO using the Excel V.2016 software. To examine the trend of crude mortality rate and YLL rates for different years, joinpoint regression was used based on the log-linear model.
During the 16-year study period (2004-2019), 6590 deaths due to unintentional injuries in children aged 0-19 years have occurred. The total YLLs due to unintentional injuries were 138 482 in males and 53 168 in females. The three main causes of YLLs in our study were transportation injuries (67.37%), drowning (7.19%) and burns (6.70%). According to the joinpoint regression analysis, the 16-year trend of YLL rate due to premature mortality was decreasing; the annual per cent change was -5.2% (95% CI -6.5% to -3.9%, p<0.001) for males and -4.3% (95% CI -5.7% to -3.0%, p<0.001) for females.
Based on the findings of this study, the trend of mortality and YLL rate has been decreasing. Road traffic injuries were the most frequent injuries and the most common cause of death. Mortality rates fell by half. To improve child survival, injuries must now be recognised as a major child health problem, and to prevent deaths from injuries in children, early and preventive measures should be taken into account.
伤害是世界范围内导致死亡和残疾的主要原因之一。本研究旨在确定伊朗南部儿童因意外伤害导致的死亡率和寿命损失年（YLL）的趋势。
在这项横断面研究中，我们根据年龄、性别和死亡年份，从电子死亡登记系统中提取了所有基于国际疾病分类（ICD-10）的意外伤害导致的死亡报告。使用世卫组织 2015 年 YLL 模板，通过 Excel V.2016 软件，对与意外伤害相关的过早死亡导致的 YLL 进行了分析。为了检查不同年份的粗死亡率和 YLL 率的趋势，我们基于对数线性模型使用了 joinpoint 回归。
在 16 年的研究期间（2004-2019 年），0-19 岁儿童因意外伤害导致了 6590 例死亡。因意外伤害导致的总 YLL 为男性 138482 年，女性 53168 年。我们研究中 YLL 的三个主要原因是交通伤害（67.37%）、溺水（7.19%）和烧伤（6.70%）。根据 joinpoint 回归分析，由于过早死亡导致的 YLL 率 16 年的趋势呈下降趋势；男性的年变化百分比为-5.2%（95%CI-6.5%至-3.9%，p<0.001），女性为-4.3%（95%CI-5.7%至-3.0%，p<0.001）。
根据本研究的结果，死亡率和 YLL 率的趋势呈下降趋势。道路交通伤害是最常见的伤害和最常见的死亡原因。死亡率下降了一半。为了提高儿童的生存率，现在必须认识到伤害是一个主要的儿童健康问题，并采取早期和预防措施来预防儿童因伤害而死亡。
