[Study on the epidemiology of HP infection among 464 school staff in Henan Province].

An epidemiological study of Helicobacter pylori (HP) infection among 464 school staff was carried out by detecting sera urease antibody. The result showed that HP infection rate was 42.03% and increased with age. It was higher among persons with upper gastrointestinal symptoms and with gastric disease than without. The rate of HP infection tended to relate to factors as educational level, income, alcohol consumption but did not reach significant level statistically. HP infection did not seem to be related to gender, members in a family and smoking.
