A causative role is now accepted forHelicobacter(formerlyCampylobacter)pyloriin type B gastritis, and evidence is accumulating thatH. pyloriinfection plays a major contributory role in peptic ulcer disease. Preliminary studies have reported that the prevalence ofH pyloriinfection increases with age, but detailed information on the prevalence of the bacteria in any defined population and on the factors that may influence the pattern of distribution remains scanty. In the present study, a sensitive enzyme-linked immunosorbent assay and a [13C] urea breath test were used to investigate the prevalence ofH. pyloriinfection among 485 healthy asymptomatic volunteers between the ages of 15 and 80 residing in the Houston metropolitan area.H. pyloriinfection was present in 52%. The prevalence ofH. pyloriinfection increased rapidly with age at 1%/yr for the overall population. The frequency ofH. pyloriinfection was higher in blacks (70%) than whites (34%) (P< 0.001); this difference remained after adjustments were made for age, gender, educational level, income, and use of tobacco or alcohol.H. pyloriinfection was independent of gender but was closely correlated with socioeconomic class. There were significant inverse correlations between age-adjusted frequency ofH. pyloriinfection and income and between educational level andH. pyloriinfection. There was no association betweenH. pyloriinfection and consumption of alcohol or nonsteroidal antiinflammatory drug use or smoking. Having pets was associated with a lower frequency ofH. pyloriinfection, but this was highly associated with higher socioeconomic status. The mode(s) of transmission ofH. pyloriis unknown, but the social patterns ofH. pyloriinfection are consistent with fecal-oral transmission as one important pathway. Socioeconomic factors seem to determine the age of acquisition.
