The prevalence and associated factors of Helicobacter pylori infection among asymptomatic adolescent schoolchildren in Sudan: a cross-sectional study.

Background: Only few data have been published on Helicobacter pylori infection in adolescents in Sub-Saharan Africa, including Sudan. The aim of the present study was to investigate the prevalence and associated factors of H. pylori infection in asymptomatic adolescents schoolchildren (aged 10-19 years) in Sudan.

Methods: A cross-sectional study was conducted from October to November 2022. The participants' sociodemographic and clinical characteristics were assessed using a questionnaire. The participants underwent a rapid H. pylori antibody test for the detection of H. pylori antibodies. Multivariate regression analyses were performed.

Results: Of the 368 enrolled adolescents, 155 (42.1%) and 213 (57.9%) were boys and girls, respectively. The median (interquartile range [IQR]) age of the total sample was 15.2 years (14.0‒16.4 years). The overall prevalence of H. pylori infection was 8.4%. In the multivariable regression analyses, only the female adolescents (adjusted odds ratio [AOR], 3.04; 95% confidence interval [CI], 1.24‒7.44) were associated with H. pylori infection. Age, parental education and occupation, and body mass index were not associated with contracting H. pylori infection.

Conclusion: H. pylori infection was detected in one of 10 adolescents in Northern Sudan. Female adolescents were at a higher risk of contracting H. pylori infection. The introduction of interventional health programs such as awareness campaigns and improving personal hygiene could lead to the reduction of the risk of H. pylori infection at early ages, especially in girls, and ensure that adolescents are healthy in their present and later lives.
