Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The incidence of seropositive helicopacter pylori infection and the frequencies of ABO blood groups and iron deficiency anemia in helicopacter pylori seropositive children.
Time Frame: baseline

by Lohman technique , height and weight were recorded for children without shoes and wearing light clothes, standing straight, with their weight uniformly distributed on both feet and their arms hanging freely on the sides. A digital scale (model 881; Seca, Hamburg, Germany).

Height measurements in centimeters. Body mass index (BMI) to age was obtained. Anemia was defined according to (WHO) age criteria; that is, hemoglobin level of <11 g/dL (110 g/L) in children <5 years, <11.5 g/dL (115 g/L) in children with ages between 5 and 12 years and <12 g/dL (120 g/L) for patients with ages between 12 and 18 years old. Serum ferritin level was measured using electro chemiluminescence (Elec Sys 2010 analyzer; Roche Diagnostics, Mannheim, Germany), and Serum iron level and total iron binding capacity (TIBC) were determined by CobasIntegra700 analyzer (Roche Diagnostics, Basel, Switzerland). Iron deficiency anemia (IDA) was defined as serum ferritin level of <-2SD for age.
