title: Prevalence and sociodemographics of reflux symptoms in Germany--results from a national survey.
abstract: BACKGROUND
  Although gastro-oesophageal reflux disease is a common gastrointestinal disorder, the prevalence rates differ depending on the population studied.
  
  
  OBJECTIVE
  To determine the prevalence of reflux symptoms in the German adult population and any associations with age, gender or socio-economic status.
  
  
  METHODS
  A total of 7124 subjects were interviewed as part of the German National Health Interview and Examination Survey, which is a representative sample of the general adult population. The prevalence of mild, moderate or severe heartburn or regurgitation was calculated. Logistic regression models were developed to determine the relationship between reflux symptoms and sociodemographic factors such as age, gender and socio-economic status.
  
  
  RESULTS
  The overall prevalence of moderate and severe reflux symptoms was 14% and 4%, respectively. The prevalence increased with age and was highest in the age group 60-69 years with 25% of these subjects reporting moderate or severe reflux symptoms. Being male, it increased the risk of mild, but not of moderate or severe symptoms. Lower socio-economic status was associated with moderate or severe symptoms.
  
  
  CONCLUSIONS
  Because of their high prevalence, reflux symptoms are of major public health importance.
