Keywords:
Prevalence, Risk factors, Helicobacter pylori, School studentsAbstract
Helicobacter pylori infection is one of the most common chronic infections and a global public health problem, affecting over 50% of the population worldwide. Childhood is the age in which most H. pylori infections tend to be acquired particularly in developing nations. This study was designed to determine the prevalence of Helicobacter pylori infection among Schoolchildren as well as to evaluate the correlation between risk factors including age, sex, education, symptoms and nutrition with the infection rate. H. pylori-antigen and H. pylori- antibody tests were used to detect the infection by H. pylori. Total 120 blood-serum samples and 120 fecal samples were collected randomly from schoolchildren comprising eleven schools at Dhamar city. Study was carried out from November 2019 to March 2020. The results revealed that the rate of infection was 75.8% of H. pylori Antigen and 74.2% of H. pylori Antibody. The highest rate of infection by H. pylori-Ag was recorded in Oqbah, Hafsah and Yemen Modern Schools, whereas H. pylori-Ab recorded the highest rate in Oqbah, Al-jawdah and Al-motafawgeen Schools. According to the gender, the rate of infection among female students was higher compared to the male students. Moreover, the highest infection of H. pylori was in students aged between six to eight. In addition, the elementary school showed high infections in correlation with education. Finally, the current study showed a significant relationship between H. pylori infection with the pathological symptoms and type of nutrition.
