Prevalence of Helicobacter pylori antibodies in children in Bloemfontein, South Africa.

BACKGROUND

An association of H. pylori infection with chronic gastritis, peptic ulceration and gastric cancer is known.

METHODS

Prevalence of IgG antibodies to Helicobacter pylori in children in the Bloemfontein, South Africa area was studied. Children attending the general pediatric outpatient department at Pelonomi Hospital in Bloemfontein were grouped according to age. A minimum of 100 children was investigated in each age group. Baseline demographic and socioeconomic data were collected.

RESULTS

The study showed a high prevalence of H. pylori antibodies. Prevalence increased with age: 13.5% in children 3 months-2 years, 48.5% at 2-5 years, 67.3% at 5-10 years and 84.2% at 10-15 years. Investigation of the socioeconomic data in relation to the prevalence of H. pylori was inconclusive.

CONCLUSIONS

This high prevalence needs further study.
