This retrospective study aimed to analyse the pattern and trend of fatal and non-fatal injuries among children under five in Mongolia from 2018 to 2022, using hospital-based national injury surveillance data to inform targeted public health interventions.
Data from 101,731 injury cases were analysed from the National Trauma and Orthopaedic Research Center's surveillance system. Injury incidence and mortality rates were calculated based on demographic characteristics and geographic distributions.
From 2018 to 2022, 101,731 children under five sustained injuries in Mongolia, with most occurring at home (78.9%) and in Ulaanbaatar (87.6%). Boys accounted for 55.7%. Ulaanbaatar had the highest non-fatal injury incidence rate (1003 per 100,000), primarily from falls (45.8%), burns (16.5%) and mechanical forces. Non-fatal injuries increased annually in Ulaanbaatar, especially among boys (6.6%) and girls (9.9%). Children aged 1-4 years and boys were at higher risk, with injuries more frequent in summer and at home. Fatal injuries (n = 715) were mostly due to suffocation (34.7%), traffic (20.7%) and drowning (13.7%). Ulaanbaatar saw a significant decrease in fatality rates (14.9% annually for boys), while traffic-related deaths rose in girls in provinces (18.6%). Mortality rates were higher among infants aged 0-11 months.
There is an increase in non-fatal injuries among children under 5 years of age in Mongolia, particularly in Ulaanbaatar, despite a declining trend in fatal injury rates. Injury rates also vary significantly across rural provinces, highlighting the need for geographically tailored policy interventions.
本回顾性研究旨在分析2018年至2022年蒙古5岁以下儿童致命伤和非致命伤的模式及趋势，利用基于医院的国家伤害监测数据为有针对性的公共卫生干预措施提供依据。
对国家创伤与矫形研究中心监测系统中的101731例伤害病例数据进行分析。根据人口统计学特征和地理分布计算伤害发病率和死亡率。
2018年至2022年，蒙古有101731名5岁以下儿童受伤，其中大多数在家中（78.9%）和乌兰巴托（87.6%）发生。男孩占55.7%。乌兰巴托的非致命伤发病率最高（每10万人中有1003例），主要原因是跌倒（45.8%）、烧伤（16.5%）和机械力。乌兰巴托的非致命伤每年都在增加，尤其是男孩（6.6%）和女孩（9.9%）。1至4岁的儿童和男孩风险较高，夏季和家中受伤更为频繁。致命伤（n = 715）主要是由于窒息（34.7%）、交通（20.7%）和溺水（13.7%）。乌兰巴托的死亡率显著下降（男孩每年下降14.9%），而各省女孩中与交通相关的死亡人数有所上升（18.6%）。0至11个月大的婴儿死亡率较高。
尽管致命伤率呈下降趋势，但蒙古5岁以下儿童的非致命伤有所增加，尤其是在乌兰巴托。农村各省的伤害率也有显著差异，这凸显了针对不同地区制定政策干预措施的必要性。
