title: Does health-related quality of life predict injury event?
abstract: BACKGROUND
  Unintentional injury is a leading threat to children's health. Some human factors have been determined as predictor of unintentional injury. Association between Health-Related Quality of Life (HRQOL) as a human factor and unintentional injuries is unclear. The objective of study is to examine the association between HRQOL and unintentional injuries among primary school children.
  
  
  METHODS
  This study was a cross-sectional conducted in Ahwaz, a city in Iran. Overall, 3375 children aged 6-10 years were randomly selected from primary school. HRQOL was measured by 56 items taken from seven domains of Netherlands Organization for Applied Scientific Research Academic Medical Center (TNO AZL) child quality of life (TACQOL) parent form. Parents were interviewed to collect information about incidence, cause and a brief description of injury within the past 12 months prior to the study.
  
  
  RESULTS
  The response rate was 3375 of 3792 (89%). There was a significant trend for increasing occurrence of injury with decreasing of HRQOL score (p was less than 0.001). Adjusted OR for injury was significantly higher in very low (2.38, 95% CI: 1.45-3.86), low (2.18, 95% CI: 1.34-3.56), and medium (1.73, 95%CI: 1.06-2.83) HRQOL groups compared to reference group (very high HRQOL). The median of total HRQOL (P less than 0.001) and all its domains (P=0.017) (except autonomous functioning) was lower in injured group compared to uninjured one.
  
  
  CONCLUSIONS
  This study found an association between HRQOL and unintentional injury among primary school children. This is a preliminary finding and further investigations with a well-defined analytical design are needed.
