title: Reliability of percentage ideal weight for height.
abstract: OBJECTIVE
  To assess the reliability of percentage ideal weight for height (%WFH) as a measure in children.
  
  
  METHODS
  Forty two dietitians calculated %WFH of six children. Eleven of the 42 repeated the calculations.
  
  
  RESULTS
  Interexaminer estimates varied by 16.5 to 40 percentage points (mean 27.8). Intraexaminer variability was also large.
  
  
  CONCLUSIONS
  %WFH is an unreliable measure of nutritional status.
