Association Between Eating Behavior, Frequency of Meals, and Functional Dyspepsia in Young Japanese Population.

Background/aims: Functional dyspepsia (FD) may be a common digestive disease worldwide and reduces the quality of life of patients. However, only a few studies have investigated the association between eating behavior and FD. The purpose of this cross-sectional study is to examine the association between eating behavior and prevalence of FD in a young Japanese cohort.
