Prevalence and risk factors of Helicobacter pylori infection among Pakistani population
Abstract
Objective: Prevalence of H. pylori infection is higher in developing countries including Pakistan. The basic purpose of this study was to investigate the prevalence of H. pylori infection and determination of possible risk factors.
Methodology: A prospective epidemiologic survey of H. pylori infection was accomplished in 2008 and 2009 involving 516 asymptomatic individuals of Barakaho, Islamabad, Pakistan. Data were obtained by questionnaire and H. pylori positivity was checked by 13C UBT.
Results: A total of 516 individuals participated in the study of which 384 (74.4%) were positive for H. pylori infection. The prevalence was 73.5% in males and 75.4% in females (p = 0.622) and increased with increasing age (p < 0.001). Presence of household animals (p = 0.004) and more family members (p = 0.025) were significantly correlated with H. pylori prevalence while no association was seen with other risk factors such as education level, drinking water source, number of rooms in house and monthly family income.
Conclusions: High prevalence of H. pylori infection in Pakistani population is comparable to the data of developing countries. H. pylori infection was significantly associated with presence of household animals and more family members.
