Abstract

Introduction:

According to WHO, more than 50% of the adult population is infected with the Helicobacter pylori, with prevalences of up to 90 %. The majority of infection occurs before 10 years of age. Since the discovery of the H. pylori (1983), it has been linked with the peptic ulcer, gastritis, gastroesophageal reflux, and even Gastric Cancer. Can be purchased at very early ages.

Methodology: a cross sectional study was conducted. The sample consisted of 250 school children of the Shuar ethnic group of the canton Sucua. The test used for the detection of Helicobacter pylori is the detection of antigens in the stool by immunochromatography. For the determination of the association we used the OR with its 95% confidence interval. It was considered statistically significant p-values < .05.

Results: The average age was 8.8 years (SD 2.0), with a predominance of women

54.4%. The 56.4 % consume potable drinking water, the 71.65 % living in overcrowded, the 42.0 % have sanitation services and the 49.2 % has sewerage services. Statistically significant association was found with the level of instruction OR 1.68, 95% CI: 1.00 - 2.84, p=0,049; latrine OR 1.99 , 95% CI: 1.17 - 3.36 , p=0.010 ; outdoor stools OR 4.32 ,

95% CI: 2.13 - 8.77 , p=0.000 ;

Conclusions: The prevalence of Helicobacter pylori infection is high in the school population in the Shuar ethnic group and is linked to the level of parental education, latrines and stools in the open air.
