Abstract

The prevalence of H. pylori infection in Jordanian schoolchildren is high, suggesting that most acquisition occurs before the age of 6 years. The seroprevalence for H. pylori increases with social deprivation.

G. lamblia and H. pylori infections among mentally challenged individuals in rehabilitation centers in Alexandria, Egypt

“…This is consistent with a previous study reporting that living in socially deprived, crowded conditions is a risk factor associated with H. pylori infection among Egyptian children and adults [44]. Low socioeconomic level and/or living in rural areas are major determinants of high H. pylori prevalence in different eastern Mediterranean countries [38,[45][46][47]. The present study was conducted within a time frame of eight months and included all the mentally challenged individuals who agreed (or whose guardian[s] agreed for them) to participate.…”

Childhood Hygienic Practice and Family Education Status Determine the Prevalence of Helicobacter pylori Infection in Iran

“…Similar to the studies from both developing and developed countries [29][30][31][32], we showed that overcrowding of living place during childhood was linked to a higher prevalence of H. pylori infection, suggesting the possibility of personto-person transmission. This positive association was retained even after adjustment for age and education.…”

Incidence of Esophageal Carcinoma Among Malays in North-Eastern Peninsular Malaysia: An Area with an Exceptionally Low Prevalence of Helicobacter pylori Infection

“…Cigarette smoking among males on the other hand is very prevalent [27]. It is interesting that the incidence rates of squamous cell carcinoma in Egypt and Jordan that have predominantly Muslim populations [19] are also relatively low whereas in those populations H. pylori prevalence is high [28,29]. Recent studies have associated squamous cell carcinoma of the esophagus with the presence of achlorhydria suggesting a possible link between H. pylori (a common cause of achlorhydria) and squamous cell carcinoma [8,30].…”
