ABSTRACT

BACKGROUND: Gastro-oesophageal reflux disease (GORD) is recognized by symptoms of heartburn and acid regurgitation. These gastro-oesophageal reflux symptoms (GORS) are common in adults, but data from adolescents are sparse. This study aimed to assess the prevalence and risk factors of GORS among adolescents in a large and unselected population. METHODS: This study was based on the Trøndelag Health Study (HUNT), a longitudinal series of population-based health surveys conducted in Nord-Trøndelag County, Norway. This study included data from Young-HUNT4 performed in 2017-2019, where all inhabitants aged 13-19 years were invited and 8066 (76.0%) participated. The presence of GORS (any or frequent) during the past 12 months and tobacco smoking status were reported through self-administrated questionnaires, whereas body mass index (BMI) was objectively measured. RESULTS: Among 7620 participating adolescents reporting on the presence of GORS, the prevalence of any GORS and frequent GORS was 33.2% (95% confidence interval [CI] 32.2 - 34.3%) and 3.6% (95% CI 3.2 - 4.0%), respectively. The risk of frequent GORS was lower among boys compared to girls (OR 0.61; 95% CI 0.46 - 0.79), higher in current smokers compared to never smokers (OR 1.80; 95% CI 1.10 - 2.93) and higher among obese compared to underweight/normal weight adolescents (OR 2.50; 95% CI 1.70 - 3.66). CONCLUSION: A considerable proportion of adolescents had GORS in this population-based study, particularly girls, tobacco smokers, and individuals with obesity, but frequent GORS was relatively uncommon. Measures to avoid tobacco smoking and obesity in adolescents may prevent GORS.

ABSTRACT

BACKGROUND & AIMS: Helicobacter pylori eradication improves the prognosis of peptic ulcer disease (PUD), dyspepsia, and possibly gastric cancer. H pylori screening tests are accurate and eradication therapy is effective. H pylori population screening seems attractive. The aim of this study was to evaluate the long-term effect of H pylori population screening and eradication on dyspepsia prevalence and the incidence of PUD, and as secondary outcomes to assess the effect on health care consumption and quality of life. METHODS: At baseline in 1998 to 1999, 20,011 individuals aged 40 to 65 years were randomized to H pylori screening and eradication or a control group with no screening. Both groups received a questionnaire on dyspepsia and quality of life. Register data were obtained for all randomized individuals. RESULTS: The baseline questionnaire response rate was 63%. Of the 5749 individuals screened, 1007 (17.5%) were H pylori positive. Complete symptom data were obtained for 8658 (69%) individuals after 13 years. Dyspepsia prevalence decreased in both groups during the follow-up period, but multivariate analysis showed no effect of H pylori screening and eradication (adjusted odds ratio, 0.93; 95% confidence interval, 0.82-1.04); compared with usual care. Intention-to-treat and per-protocol analyses of register data provided similar results. H pylori screening neither reduced PUD incidence significantly (adjusted odds ratio, 0.88; 95% confidence interval, 0.70-1.11) nor did it have a beneficial effect on health care consumption. H pylori screening had no long-term effect on quality of life. CONCLUSIONS: This randomized clinical trial with 13 years of follow-up evaluation, designed to provide evidence on the effect of H pylori population screening, showed no significant long-term effect when compared with usual care in this low-prevalence area. ClinicalTrials.gov identifier: NCT02001727.

ABSTRACT

OBJECTIVE: Tobacco smoking is a risk factor for gastroesophageal reflux, but whether other tobacco products increase the risk is unclear. The aim of this study was to investigate if snus increases the risk of gastroesophageal reflux symptoms (GERS). MATERIAL AND METHODS: The study was based on the third Nord-Trøndelag health study (HUNT3), a population-based study of all adult residents in Nord-Trøndelag County, Norway, performed in 2006-2009. The association between self-reported severe heartburn/regurgitation and snus use was assessed by logistic regression. RESULTS: Compared to never snus users, daily snus users had a reduced risk of GERS (OR 0.77, 95% confidence interval [CI] 0.64-0.93), while previous snus users and those using <2 boxes of snus/month had an increased risk (OR 1.20, 95% CI 1.00-1.46 and OR 1.41, 95% CI 1.02-1.96, respectively). There was no association between age when starting using snus and GERS. Snus users who started using snus to quit or cut down on cigarette smoking, who started using both snus and cigarettes or cigarettes alone had an increased risk of GERS. Snus users <30 years of age had an increased risk of GERS (OR 1.49, 95% CI 1.02-2.16), while those aged between 50-60 and 60-70 years had a reduced risk (OR 0.67, 95% CI 0.49-0.93 and OR 0.51, 95% CI 0.28-0.94, respectively). CONCLUSIONS: Daily snus users had a reduced risk of GERS. However, previous snus users and subgroups of snus users had an increased risk of GERS indicating reverse causality, such that snus use could increase the risk of GERS.

ABSTRACT

OBJECTIVES: Gastroesophageal reflux disease (GERD) is a highly prevalent disorder. This study assessed the risk factors of new-onset gastroesophageal reflux symptoms (GERS). METHODS: The study was based on the HUNT study, a prospective population-based cohort study conducted in 1995-1997 and 2006-2009 in Nord-Trøndelag County, Norway. All inhabitants from 20 years of age were invited. Risk factors of new-onset heartburn or acid regurgitation were examined using logistic regression, providing odds ratios (OR) and 95% confidence intervals (CI). RESULTS: A total of 29,610 individuals were included (61% response rate). Participants reporting no GERS at baseline and severe GERS at follow-up (new-onset GERS; n=510) were compared with participants reporting no complaints at both times (n=14,406). Increasing age (OR 1.01 per year, 95% CI 1.00-1.02) was positively associated, whereas male sex (OR 0.81, 95% CI 0.66-0.98) and higher education (OR 0.69, 95% CI 0.56-0.86) were negatively associated with new-onset GERS. Gain in body mass index (BMI) was dose-dependently associated with new-onset GERS (OR 1.30 per unit increase in BMI, 95% CI 1.25-1.35), irrespective of baseline BMI. Previous and current tobacco smoking were associated with new-onset GERS (OR 1.37, 95% CI 1.07-1.76 and OR 1.29, 95% CI 1.00-1.67, respectively). Tobacco smoking cessation was associated with new-onset GERS among those with gain in BMI upon quitting (OR 2.03, 95% CI 1.31-3.16, with >3.5 BMI units increase). CONCLUSIONS: New-onset GERS were associated with increasing age, female sex, lower education, gain in BMI, and ever tobacco smoking. Tobacco smoking cessation was associated with new-onset GERS among those who gained weight upon quitting.
