Purpose The aim of this systematic review was to describe the prevalence of Helicobacter pylori infection in specific occu - pational groups and to compare them with the general population. Methods We searched PubMed® to identify original studies reporting the prevalence of H. pylori infection in occupational groups. The differences between occupational groups and the general population were analyzed taking into account the direction and statistical significance of the differences observed when comparing each occupational group with a reference group (either recruited in the same study or using an external comparator). Results A total of 98 studies addressing the prevalence of H. pylori infection in occupational groups were included in the systematic review. Overall, health professionals showed a significantly higher prevalence of H. pylori infection than the general population, especially among those working at gastrointestinal units. Similar results were found in subjects involved in agricultural, forestry and fishery, as well as in sewage workers, miners, and workers at institutions for the intellectually disabled, although differences were less pronounced. Conclusions Our results show an occupational risk of H. pylori infection supporting the role of oral–oral, fecal–oral, and zoonotic transmission. Studies comparing specific occupational groups with adequate comparators may contribute to
