title: Dietary habits and gastroesophageal reflux disease in preschool children.
abstract: OBJECTIVE
  To identify the relationship between dietary habits and childhood gastroesophageal reflux disease (GERD) in preschool children.
  
  
  METHODS
  We performed a questionnaire study to analyze the relationship between dietary habits and GERD in 85 preschool children with GERD and 117 healthy children of the same age.
  
  
  RESULTS
  Irregular and picky eating were more p-revalent in the GERD group than in the control group (odds ratio [OR], 4.14; 95% confidence interval [CI], 1.37-12.54 and OR, 4.96; 95% CI, 1.88-13.14, respectively). The snack preferences and the late night eating habits were significantly more prevalent in the GERD group than in the control group (OR, 3.83; 95% CI, 1.23-11.87 and OR, 9.51; 95% CI, 2.55-35.49, respectively). A preference for liquid foods was significantly more prevalent in the GERD group (OR, 9.51; 95% CI, 2.548-35.485). The dinner-to-bedtime interval was significantly shorter in the GERD group than in the control group (157.06±48.47 vs. 174.62±55.10, P=0.020). In addition, the time between dinner and bedtime was shorter than 3 hours in 47 children (55.3%) of the GERD group and 44 (37.6%) of the control group. This difference was statistical significance (P=0.015).
  
  
  CONCLUSIONS
  Dietary habits such as picky and irregular eating, snack preference, a preference of liquid foods, late night eating, and a shorter dinner-to-bedtime interval had a significant correlation with GERD. Further large-scale studies are necessary to confirm our results.
