title: Reference values of body composition indices: the Korean National Health and Nutrition Examination Surveys.
abstract: OBJECTIVE
  An increase in the prevalence of obesity has been observed in children and adolescents. As remarkable changes in body composition occur with growth during the adolescent period, it is important that changes in body composition be monitored. The purpose of this study was to propose reference percentile values for body composition indices including body mass index (BMI) in children and adolescents in Korea.
  
  
  METHODS
  This study was performed using data from the Fourth and Fifth Korea National Health and Nutrition Examination Surveys. Body composition data were obtained using dual-energy X-ray absorptiometry. The percentile curves of body composition indices were constructed by the LMS method.
  
  
  RESULTS
  A total of 2123 children and adolescents between the ages of 10 and 19 years were included in this study. We obtained the percentile curves for BMI and body composition indices.
  
  
  CONCLUSIONS
  The reference values for body composition from this study could help with assessing body composition in Korean adolescents.
