The wide variability in economic development levels among different regions in China results in the migration of millions of households to more developed areas. Death records from 2008 to 2012 of children aged 0-17 years old from the vital surveillance system of Guangzhou were used to determine if death rates were different for resident and migrant children. A total of 1358 injury-related deaths were identified with rates rising slightly from 2008 to 2012 both in resident and migrant populations. The total crude incidence rate of injury death was significantly higher among migrant households (29.50/100 000) compared with resident households (8.42/100 000). The adjusted rate in migrant households was 3.50 (95% CI 3.14 to 3.89) times higher than in resident households. Drowning and traffic crashes represented the most common causes of death and residences were the most frequent site of injury-related death for both groups of children. Migrant children were at a significantly higher risk of injury-related mortality compared with local resident children.
中国不同地区经济发展水平差异巨大，导致数百万家庭迁移至更发达地区。利用广州生命监测系统中2008年至2012年0至17岁儿童的死亡记录，来确定常住儿童和流动儿童的死亡率是否存在差异。共识别出1358例与伤害相关的死亡，常住和流动人口的死亡率从2008年到2012年略有上升。流动家庭伤害死亡的总粗发病率（29.50/10万）显著高于常住家庭（8.42/10万）。流动家庭的校正发病率比常住家庭高3.50倍（95%可信区间3.14至3.89）。溺水和交通事故是最常见的死亡原因，住所是两组儿童与伤害相关死亡最频繁的地点。与本地常住儿童相比，流动儿童与伤害相关的死亡风险显著更高。
