摘要目的 探讨广州市中小学生烧烫伤发生的影响因素.方法 采用整群随机抽样方法,在广州市区县中小学按性别、班级1∶1配对原则,选择428对烧烫伤病例和对照组,采用单因素和多因素条件logistic回归分析.结果 广州市中小学生烧烫伤发生主要部位是上肢(57.9%),主要发生地点是家中(58.2%).51.0%烧烫伤是热水导致的;43.9%的烧烫伤需要医疗单位处理;7.7%伤后留下后遗症(活动不如往常、功能受限、致残).多因素分析结果显示,住宿生(OR=2.47)、母亲年龄大(OR=1.03)、非核心家庭(OR=1.25～1.84)等是烧烫伤发生的影响因素.独生子女(OR=0.60)、睡眠时间充足(OR=0.84)、学习成绩好(OR=0.85)、母亲高学历是烧烫伤发生的保护因素.结论 广州市中小学生发生烧烫伤部位以上肢为主,家中是发生烧烫伤的主要场所.

abstractsObjective To investigate the relative factors of burn injury among primary and secondary school students in Guangzhou and to provide scientific evidence for intervention.Methods 1:1 case-control study was conducted in 428 cases and 428 controls based on different sex and classes. The relationship between relative factors and burn injury was analyzed by univariate and multivariate conditional logistic regression. Results Following facts were discovered: burn injury mainly occurred in the upper limbs (57.9%), home was the place that most of burn injury (58.2%)took place, 51.0% of the burn injuries was caused by hot liquid, 43.9% burn injury needed medical treatment and 7.7% burn injury left with sequelae as dysfunction or disability. Data from the multivariate conditional logistic regression showed that boarding students (OR=2.47), older age of the mothers (OR=1.03), non-nuclear family (OR=1.25-1.84) were risk factors of burn injury.Being the only child (OR=0.60), having sufficient time for sleep (OR=0.84), good performance record (OR=0.85), higher maternal education background were protective factors on burn injury.Conclusion Among primary and secondary school students in Guangzhou, burn injury mainly occurred in the upper limbs, and home was the place that most of burn injury took place.
