This study analysed trends in the unintentional injuries specific mortality rates among children under age five (UI-specific U5MRs) in urban and rural areas in the Sichuan province of western China. Data were obtained from the National Health Statistics Survey System. The Cochran-Armitage trend test was used to analyse the trends in UI-specific U5MRs and the proportion of unintentional injury deaths to total deaths. The Poisson regression model was used to compare the UI-specific U5MRs between rural and urban areas. The overall UI-specific U5MRs decreased from 3.8 to 1.7 per 1,000 live births from 2009 to 2017, with an average annual decline in the rates of 8.78% and 10.05% in urban and rural areas, respectively. The UI risk of death in rural areas was approximately 1.95 times that in urban areas (95% CI: 1.73-2.18; p < 0.01). A total of 49.9% of all the children in the study did not receive any treatment before death caused by UI. The UI-specific U5MRs significantly declined in Sichuan province from 2009 to 2017, but large disparities in UI-specific U5MRs in urban and rural areas still exist. Reducing the U5MRs due to UI should be a major public health concern in western China.
本研究分析了中国西部四川省城乡地区 5 岁以下儿童（U5MR）特定意外伤害死亡率（UI-specific U5MR）的变化趋势。数据来自国家卫生统计调查系统。采用 Cochran-Armitage 趋势检验分析 UI-specific U5MR 和意外伤害死亡比例随时间的变化趋势。采用 Poisson 回归模型比较城乡地区的 UI-specific U5MR。2009 年至 2017 年，总体 UI-specific U5MR 从每千例活产 3.8 例降至 1.7 例，城市和农村地区的年平均下降率分别为 8.78%和 10.05%。农村地区 UI 死亡风险约为城市地区的 1.95 倍（95%CI：1.73-2.18；p<0.01）。研究中共有 49.9%的儿童因 UI 死亡前未接受任何治疗。2009 年至 2017 年，四川省 UI-specific U5MR 显著下降，但城乡地区 UI-specific U5MR 仍存在较大差异。降低 UI 导致的 U5MR 应成为中国西部的主要公共卫生关注点。
