Abstract

Abstract Objectives The Infant Gastroesophageal Reflux Questionnaire Revised (I-GERQ-R) is used to score and evaluate gastroesophageal reflux (GER) related symptoms such as regurgitation, irritability and crying. A cut-off of ≥ 16 has been suggested to discriminate between GER and GER-disease. However, age-specific normal values were not assessed. Aim of this study was to determine age-specific normal values in healthy infants. Study design: Cross-sectional survey in healthy infants aged 0–24 months during their regular check-ups at well-baby clinics and through an online questionnaire using the I-GERQ-R. Infants with a history of (suspected) GER-disease were excluded. Spearman’s correlation coefficient was calculated to explore age-related trends. Results A total of 979 healthy infants (47% male, median age 6 [0–24] months) were included. Median I-GERQ-R score, regardless of age, was 6 (range: 0–27). I-GERQ-R scores significantly decreased with age (rs=-0.569, p < 0.001). Of all infants, 49 (5%) had a score of ≥ 16 which previously has been considered ‘suggestive of GER-disease’. Scores of ≥ 16 were most frequently seen in newborns aged 0–4 months (16% in 0–1 months to 4% in 3–4 months) and disappeared after the age of 16 months. High scores in the first months of life were caused by a high prevalence of regurgitation, colic-associated symptoms and hiccup frequency. Conclusion Age-dependent normal values for the I-GERQ-R show that reflux symptoms decrease in the first 24 months of life in healthy infants. Scores of ≥ 16 should not necessarily be considered abnormal in young infants. Validation as a diagnostic tool for GER-disease using age-appropriate normal values is needed.
