title: Establishing a standard definition for child overweight and obesity worldwide: international survey.
abstract: OBJECTIVE
  To develop an internationally acceptable definition of child overweight and obesity, specifying the measurement, the reference population, and the age and sex specific cut off points.
  
  
  METHODS
  International survey of six large nationally representative cross sectional growth studies.
  
  
  METHODS
  Brazil, Great Britain, Hong Kong, the Netherlands, Singapore, and the United States.
  
  
  METHODS
  97 876 males and 94 851 females from birth to 25 years of age.
  
  
  METHODS
  Body mass index (weight/height(2)).
  
  
  RESULTS
  For each of the surveys, centile curves were drawn that at age 18 years passed through the widely used cut off points of 25 and 30 kg/m(2) for adult overweight and obesity. The resulting curves were averaged to provide age and sex specific cut off points from 2-18 years.
  
  
  CONCLUSIONS
  The proposed cut off points, which are less arbitrary and more internationally based than current alternatives, should help to provide internationally comparable prevalence rates of overweight and obesity in children.
