title: Association between Helicobacter pylori infection and adult height.
abstract: OBJECTIVE
  A cross-sectional survey was performed to evaluate the association between H. pylori and adult height.
  
  
  METHODS
  H. pylori infection was assessed using a 13C-urea breath test and height measured by a research nurse using a stadiometer in participants between the ages of 40-49 years.
  
  
  RESULTS
  Height was measured in 2932/3682 participants that attended and were evaluable. H. pylori infected women were 1.4 cm shorter than uninfected women (95% confidence interval, CI = 0.7-2.1 cm) and this statistically significant difference persisted after adjusting for age, ethnicity, childhood and present socio-economic status (H. pylori positives 0.79 cm shorter; 95%CI: 0.05-1.52 cm). H. pylori positive men were 0.7 cm shorter than uninfected men but this did not reach statistical significance (95% CI: -0.1-1.5 cm).
  
  
  CONCLUSIONS
  Although H. pylori infection is associated with reduced adult height in women, this maybe due to residual confounding.
