Studies in 1,120 Peruvian adults suffering from upper gastrointestinal symptoms and stratified according to socioeconomic level., age., and sex have shown the following; Rates of Helicobacter pylori infection range from 3% in patients with normal gastric mucosa to 92% in cases of chronic active gastritis. Age-specific infection rates do not vary with the severity of active gastritis and are similar in men from low and high socioeconomic levels. Women from higher socioeconomic backgrounds show a significantly lower age-specific rate of infection than women from lower levels or from men from either level. In addition, a seroepidemiologic survey of children, predominantly from families from lower socioeconomic levels, demonstrates that infection begins for many of them in the first years of life.
