Abstract:

Background: Nearly 50% of the world’s population is estimated to be infected with H. pylori but the prevalence varies greatly
among countries and among population groups within the same country. The overall prevalence of H. pylori infection is
strongly correlated with socio-economic conditions.
Objective: To determine the prevalence and the possible risk factors for Helicobacter Pylori infection among adults at Jinka
Zonal Hospital, Debub Omo Zone, Southwest Ethiopia.
Methods: A hospital based cross-sectional study was conducted among 349 adults from December 2012 to February 2013.
All Stool specimens were screened for fecal H. pylori antigen. Besides, all participants were interviewed using structured
questionnaire.
Results: A total of 150 (43%) males and 199 (57%) females were involved in the study. The age of participants were ranged
between 20-89 years with a mean age of 36.7+14.7 and median 32 years. The overall prevalence of H. pylori infection was
50.7% (177/349). H. pylori infection were positively associated with those whose occupation were agrarians (OR=1.85 (95%
CI 1.02-3.39, p=0.045); being male (OR=1.98 (95% CI 1.42-3.29, p=0.011), more than 5 persons living in the same house,
[(OR=1.53(95% CI 1.00-2.34, p=0.048)]; those practiced open field defecation/no toilet use, (OR=6.75 (95% CI 2.11-21.61),
p=0.001); those who never wash their hands after toilet, (OR=2.86 (95% CI 1.30-3.27, p=0.009). But a minimum alcohol
consumption was negatively associated with H. pylori bacteria, (OR=0.39 (0.23-0.67, p=0.001).
Conclusion & recommendation: The overall prevalence of H. pylori infection in Debub Omo Zone was 50.7%. Poor hygienic
practices and crowding were positively associated with H. pylori infection. On the other hand, consumption of little alcohol
might protect infected against H. pylori bacteria. Increasing the awareness of the communities toward good hygienic practices
might reduce the transmission of H. pylori infection.
