While several studies have demonstrated a decline in the overall prevalence of Helicobacter pylori infection in developed countries, there is variability in the burden of infection linked to socioeconomic status and living conditions. Improved socioeconomic status, living conditions and the availability of H. pylori-eradication therapy have been associated with a lower prevalence of infection in First World populations, yet immigrants and indigenous people continue to have a high burden of H. pylori infection and disease. Although the changing prevalence of H. pylori infection in children has been recognized in a few reports, further studies are required to determine the impact of H. pylori infection in this population. Moreover, additional studies are required for those populations at risk.
虽然多项研究表明，发达国家幽门螺杆菌感染的总体患病率有所下降，但与社会经济地位和生活条件相关的感染负担存在差异。社会经济地位的改善、生活条件的改善以及幽门螺杆菌根除疗法的可及性，与第一世界人群较低的感染患病率相关，但移民和原住民仍然承受着较高的幽门螺杆菌感染和疾病负担。尽管少数报告已经认识到儿童幽门螺杆菌感染患病率的变化，但仍需要进一步研究以确定幽门螺杆菌感染对这一人群的影响。此外，对于那些高危人群也需要进行更多研究。
