Abstract: | Various reports on the prevalence of gastroesophageal reflux disease (GERD) and uninvestigated dyspepsia have been conducted
in Western countries. We sought to determine the frequency of GERD symptoms and uninvestigated dyspepsia in Korea. Telephone
interviews were conducted with 1,044 individuals. Of all subjects, 7.1% reported that GERD symptoms were present at least
once a week, and 3.8% at least twice a week. The prevalence of heartburn according to educational level and acid regurgitation
according to age was significantly different (P < 0.05). The prevalence of uninvestigated dyspepsia was reported as 12.2%. Dyspepsia was divided into subgroups of 34% ulcer-like,
56% dysmotility-like, and 10% nonspecific. The occurrence of dyspepsia did not vary according to age, gender, educational
level and household income. As frequency of GERD symptoms increased, quality of life significantly decreased. We concluded
that GERD symptoms and uninvestigated dyspepsia were prevalent in Korea. The prevalence was similar to that of other Asian
countries. |
