title: [A matched case-control study on the risk factors of burn injury among primary and secondary school students in Guangzhou].
abstract: OBJECTIVE
  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.
  
  
  CONCLUSIONS
  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.
