Eating Behaviours and Prevalence of Gastroesophageal Reflux Disease in Japanese Adult Patients With Type 2 Diabetes Mellitus: The Dogo Study.

OBJECTIVES

In the general population, late-night dinner is positively associated with gastroesophageal reflux disease (GERD). No evidence exists regarding the relationship between eating behaviours and GERD in patients with type 2 diabetes mellitus, though the prevalence of GERD in patients with type 2 diabetes is higher than in those without diabetes. We conducted this study to investigate the association between eating behaviours and GERD in Japanese patients with type 2 diabetes.

METHODS

The study's subjects were 817 Japanese patients with type 2 diabetes. GERD was defined as being present when a subject had a Quality of Life and Utility Evaluation Survey Technology (QUEST) score of 4 or higher. The assessment of eating behaviour was performed by self-administered questionnaire. Subjects were considered positive for late-night dinner if they answered yes to the question "Do you eat dinner within 2 hours before bedtime at least 3 times per week?

RESULTS

The prevalence values of GERD, skipping breakfast, bedtime snacking, late-night dinner and fast eating were 32.0%, 13.7%, 27.1%, 28.8%, and 44.4%, respectively. Late-night dinner was independently positively associated with GERD in patients with type 2 diabetes; the adjusted odds ratio was 1.46 (95% CI 1.03 to 2.05). No relationships were found between skipping breakfast, bedtime snacking or fast eating and GERD.

CONCLUSIONS

Late-night dinner may be positively associated with GERD in Japanese patients with type 2 diabetes.
