Abstract:
This descriptive analytical prospective cross sectional study was performed
with the aim to determine Helicobacter pylori infection in primary school
children in the 19 educational sectors of Tehran. Mean age was 9.17±1.53
years and multistage sampling was performed. Helicobacter pylori antibody
was estimated in 1665 subjects (945 girls, 57%; 720 boys, 43%). 1236 (74%) were
uninfected and 429 (26%) were seropositive. The infected girls were 220 (23%)
and of boys were 209 (29%): indicating that the difference was significant between
the sexes. The least (18%) and the highest (43%) Helicobacter pylori
infection rate was in the 7-year and the 12 year age groups, respectively. The
difference was significant between the age groups (p = 0.000). Based on the
geographical regions of Tehran, Helicobacter pylori infection was highest
(33%) in South Tehran and lowest (21%) in North Tehran, which was statistically
different (p = 0.002).
