BackgroundHelicobacter pylori infection is associated with the development of chronic gastritis, peptic ulcer disease, and gastric cancer. Current clinical recommendations are that H. pylori test-and-treat should be individualized based on comorbidities and patient preferences among populations at increased risk for certain morbidities. However, knowledge, attitudes and practices regarding H. pylori among potential patient populations are largely unknown.MaterialsWe conducted a literature review to assess knowledge, attitudes, and practices of patients or community populations around H. pylori transmission, prevention, and associated morbidity.ResultsNine studies met the inclusion criteria, all published between 1997 and 2014. Eight studies evaluated perception of H. pylori among at-risk populations, while one study evaluated perception among a general population. The studies suggest inconsistencies between the perceptions of these populations and the established understanding of knowledge, attitude, and preventive practices for H. pylori among even at-risk populations.ConclusionTo adequately respond to current test-and-treat recommendations for treatment of H. pylori, general population education must be implemented, especially among at-risk populations. Further work is needed within at-risk populations in the United States to determine prevalence of H. pylori and their current knowledge if adequate prevention strategies are to be designed.
