title: [Does the intensity of acid gastroesophageal reflux influence chosen parameters of physical development in children and youth?].
abstract: THE AIM OF THE STUDY was to analyse physical development of children and youth with gastroesophageal reflux disease.
  
  
  METHODS
  one hundred thirteen patients between 2 and 18 years of age, with gastroesophageal reflux disease were included in the study. Height and weight were also analysed using the percentile chart of Warsaw children from 1999. Patients were divided into three groups according to the intensity of gastroesophageal reflux in 24-hours pH-metry: group I: minimal degree of gastroesophageal reflux - 3,4-9,9% total time (n=52), group II: moderate degree of gastroesophageal reflux - 10-19,9% total time (n=39), group III: significant degree of gastroesophageal reflux > 20% total time (n=22).
  
  
  RESULTS
  in group I, weight less than 3 percentile was found in 1,9% patients, height in 5,76%, weight between 3 and 10 percentile in 11,53%, height in 3,80%, weight between 90-97 percentile in 3,80%, height in 15,38% and weight above 97 percentile in 11,53%, height in 15,38%. In group II weight less than 3 percentile was found in 2,56% patients, height less than 3 percentile was not observed, weight between 3 and 10 percentile in 11,53%, height in 2,56%, weight above 97 percentile in 7,69%, height in 12,82% and weight between 90-97 percentile in 5,12%, height in 10,24%. In group III, weight and height less than 3 percentile was found in 13,63%, weight between 3 and 10 percentile in 13,63%, height in 4,54%, weight above 97 percentile in 4,54%, height in 13,63%, weight between 90-97 percentile in 18,18%, height in 22,72%.
  
  
  CONCLUSIONS
  no statistically significant correlations between the intensity of gastroesophageal reflux and the weight and height in children and youth were found.
