Prevalence of Helicobacter pylori infection in Korean children : inverse relation to socioeconomic status despite a uniformly high prevalence in adults.
The prevalence of Helicobacter pylori infection in US adults was shown to be inversely correlated with the socioeconomic status of the family during childhood, and it was suggested that this was additional evidence of transmission occurring in childhood.
The present study of H.
Pylori infection was conducted in South Korea, which has emerged as a developed country in the last two decades.
The authors attempted to determine whether there was a difference in prevalence of H. pylori infection in Korean children of different socioeconomic classes despite the high prevalence of infection in childbearing adults.
The authors also attempted to identify the factors responsible for the different patterns of transmission by estimating the age-specific prevalence of H. pylori infection in 413 healthy 1-to 75-year-old asymptomatic volunteers who resided in Seoul.
H. pylori status was evaluated using an enzyme-linked immunosorbent assay for anti-H. pylori immunoglobulin G. Demographic data were obtained from each individual, and socioeconomic class was assessed by the education level of the adults and of the children's parents as well as family income.
H. pylori infection was present in 75% of adults and 22% of children, and its prevalence increased with age (p<0.001).
In adults, the rate of infection was high and independent of socioeconomic class.
In children, it was inversely related to the socioeconomic class of the child's family : 12% among upper socioeconomic cla...
