Abstract

Background/Aims
The prevalence of Helicobacter pylori (H. pylori) infection is related with socioeconomic status. The aim of our study was to investigate the seropositivity of H. pylori in health check-up subjects and to find out the affecting factors. Methods: From January to August in 2007, 602 health check-up subjects responded to the self administered questionnaires. The anti-H. pylori IgG antibody was measured. Results: The seropositivity rate of H. pylori was 65% in 602 subjects and 225 (37.4%) has been found to have history of H. pylori eradication therapy. The seropositivity rate of H. pylori was 67.6% (200/296) in male and 62.4% (192/306) in female subjects. The seropositivity rate was 63.7% (240/377) in subjects without history of H. pylori eradication. Income has inverse relationship with the seropositivity rate (p=0.011). Conclusions: The seropositivity rate of H. pylori in the subjects without history of eradication was still high, 63.7% in 2007. The inverse relationship of income with seroprevalence of H. pylori suggests that socioeconomic status is important factor for the seroprevalence rate of H. pylori.
