  1. Seroprevalence of Helicobacer pylori in Chile : vegetables may serve as one route of transmission.

    Article - En anglais

    Helicobacter pylori infection is very common in Chilean adults, but the age-related prevalence, risk factors for infection, and mode of transmission in Chilean children are unknown.

    An ELISA was used to test for H. pylori antibodies in 1815 Chileans <35 years of age.

    Seropositivity was >60% in lower socioeconomic groups.

    H. pylori seropositivity correlated with increased age, low socioeconomic status, and consumption of uncooked vegetables by use of a logistic regression analysis.

    Risk factors that reached marginal significance were consumption of uncooked shell-fish, female sex, and residence in Santiago.
