Overview
H.pylori inhabits more than 50% of world's population, especially in developing countries.The prevalence of infection increases with age. The prevalence of H.pylori is higher in developing countries than that in developed countries. In the United States, H.pylori infection is a common disease that tends to affect African Americans, Hispanics, and the elderly compared to whites.
Epidemiology and Demographics
Prevalence
- H.pylori inhabits more than 50% of world's population especially in developing countries.[1]
Age
- All age groups may develop H.pylori infection
- The prevalence of infection increases with age.[2]
- About 30%-50% of H.pylori infections are acquired during childhood which increases to 90% during adulthood in developing countries.[3]
- H.pylori infection in developed countries is less common in children and reaches upto 60% with increasing age.[4]
- In united states, 20% of adolescents are infected with H.pylori when compared to 90% in by 5 years of age in developing countries.[5]
- Children differ from adults with respect to H.pylori infection in following terms of:[6][7]
- Prevalence of infection
- High rate of antibiotic resistance
- The near-absence of gastric malignancies
- Age specific problems with diagnostic tests and medications
Gender
- Males are more commonly affected with H.pylori infection than females.[8]
Race
- In United States, H.pylori infection is a common disease that tends to affect African Americans, Hispanics, and the elderly compared to whites.[9]
Developing countries
- The prevalence of H.pylori is higher in developing countries than that in developed countries.[10]
- H.pylori infection is common in southern and eastern Europe, Mexico, South America, Africa, most Asian countries, and aboriginal people in North America.[11][12]
Developed countries
- The prevalence of H.pylori is declining in the United States.
- In United states, approximately 25% of children between 6-19 years old are infected.[13]
- The incidence rates are high in Japan, Columbia, Costa Rica and China, and comparatively low in the United States.
