外来民工子弟学校儿童非故意伤害危险因素的病例对照研究

  目的  探讨外来民工子弟学校儿童非故意伤害的危险因素。  方法  采用1:1匹配的病例对照研究，以同班级、同性别和年龄相差不超过两岁为原则，对外来民工子弟学校发生非故意伤害的的332例儿童进行1:1的匹配。调查以问卷为基础，采用EpiData 3.1软件建立数据库，SPSS 23.0软件进行单因素、多因素条件Logistic回归模型分析。  结果  多因素Logistic回归分析模型结果表明，看护人在儿童考试前施加压力、看护人的性格为外向型和中间型、看护人的文化程度为文盲和小学、儿童的神经症行为是外来民工子弟学校儿童发生非故意伤害的危险因素。其调整后的比值比（odd ratio，OR）和95%的置信区间（confidence interval，CI）分别为2.086（95%CI:1.263~3.444）、2.074（95%CI:1.275~3.372）、1.796（95%CI:1.158~2.784）、1.867（95%CI:1.280~2.722）、2.458（95%CI:1.169~5.168）、1.466（95%CI:1.012~2.124）。  结论  外来民工子弟学校儿童非故意伤害与其看护人以及儿童自身的危险行为有关，应及时采取有效措施降低非故意伤害的发生。

A case-control study on the risk factors of unintentional injuries among internal-migrant children

  Objective  To explore risk factors of unintentional injuries among internal-migrant children.  Methods  A 1:1 matched case-control study was conducted between 332 internal-migrant children with unintentional injuries, based on the principle that same class, same gender and age was no more than two years old. The survey was based on the unified questionnaire. Epi Data 3.1 was used to establish database and SPSS 23.0 was used for univariate analysis and multi-conditional Logistic regression analysis.  Results  Multi-conditional Logistic regression analysis model indicated that caregiver put pressure on children before exam and the adjusted odd ratio (OR) was 2.086 and 95% confidence interval (CI) was 1.263-3.444, caregiver's character was extravert type (OR=2.074, 95% CI: 1.275-3.372) or middle type (OR=1.796, 95% CI: 1.158-2.784), caregiver's educational background was illiteracy (OR=1.867, 95% CI: 1.280-2.722) or primary school (OR=2.458, 95% CI: 1.169-5.168), the neurotic behaviors of children (OR=1.466, 95% CI: 1.012-2.124) were risk factors of unintentional injuries among internal-migrant children.  Conclusions  The characteristics related to internal-migrant children's caregiver and children's neurotic behaviors are associated with the occurrence of unintentional injuries. Immediate and effective measures should be taken to ease the high injury prevalence and prevent the unintentional injuries among internal-migrant children.
