### Question: Does Helicobacter pylori infection relate to iron deficiency anaemia in prepubescent children under 12 years of age?

### Context: 1: Haemoglobin levels, iron parameters and serum IgG antibodies to H. pylori were measured in 693 children aged 9 to 12 y.
2: No significant differences in the seroprevalence of H. pylori infection and antibody titres to H. pylori were found between the IDA group and the non-anaemic controls.


###Response: H. pylori infection does not seem to contribute to iron deficiency in prepubescent children.
