BACKGROUND: A self-assessment questionnaire, the GERD-Questionnaire (GERD-Q) was used to determine the prevalence of GERD in adolescents, describe the related factors, and determine the impact on quality of life (QoL). METHODS: The incidence of GERD was evaluated using the GERD-Q in adolescents aged 12–18 years. The Pediatric Gastroesophageal Reflux Disease Symptom Questionnaire and Quality of Life Questionnaire (PGSQ-A) for adolescents were additionally administered. Some factors considered related to GERD were also evaluated. RESULTS: The 520 adolescents were included. The prevalence of suspected GERD, according to a GERD-Q cutoff score of ≥7 was 32.9%, and those drinking soda were 1.7 times more likely to have GERD (95% confidence interval, 1.3–2.2; p<0.001). However, soda consumption was not a risk factor for development of GERD symptoms. Applying a cutoff score of ≥8, only 10.9% of the participants had a positive GERD score, but the association with soda consumption persisted. The median PGSQ-A score in subjects suspected of GERD was 8 (range 0–37) on weekends and 1 (range 0–17) during weekdays (p<0.001) compared to those not suspected of GERD, with a median of 2 (range 0–27) during weekends and 0 (range 0–10) during weekdays. Heartburn, regurgitation, and extraesophageal symptoms correlated significantly with QoL (p<0.001). CONCLUSION: The prevalence of suspected GERD in adolescents was 32.9% or 10.9%, depending on the cutoff score used. There was a statistically significant difference in PGSQ-A scores between the subjects suspected or not of GERD, indicating an impaired QoL.
