To evaluate the role of faecal-oral transmission in the spread of Helicobacter pylon.
A cross-sectional comparison of the patterns of hepatitis A and H. pylori seropositivity.
At interview, blood samples and questionnaire data were collected from a random sample of 1528 healthy subjects aged 20-85 years from the Republic of San Marino.
Serum samples from each subject were then tested for anti-H. pylori and anti-hepatitis A antibodies.
Overall, 529 of 670 H. pylori-seropositive subjects (78.9%) and 460 of 858 H. pylori-seronegative subjects (53.6%) were hepatitis A seropositive (P<0.01 ; odds ratio=3.2 ; confidence interval 95%=2.6-4, i).
This association remained after adjustment by a multiple logistic regression analysis for the confounding effect of age and length of schooling, as surrogate for socio-economic status (OR=2.0 ; CI 95%=1.3-3.3).
The age-specific prevalence curves for H. pylori and hepatitis A infections showed a parallel increase by age, although to a lesser extent for H. pylori.
