Deprivation timing of preschool infections and H. pylori seropositivity at age 49-51 years: the Newcastle thousand families birth cohort

摘要

BackgroundHelicobacter pylori infection is acquired in early childhood and persists for life (or until eradication treatment is taken). Seropositivity of H. pylori at age 49-51 years was assessed in relation to socio-economic deprivation in early life and the timing of other childhood infections common at that time.
