Differential Helicobacter pylori infection rates in two contrasting gastric cancer risk regions of South China

Background: Carriers of Helicobacter pylori are believed to have a three‐ to six‐fold increased risk of developing gastric cancer. We have recently conducted a simultaneous cross‐sectional population study on the prevalence of H. pylori infection in a cohort of asymptomatic adult volunteers in two contrasting gastric cancer risk regions of South China, Hong Kong and Changle of Fujian. Their mean annual gastric cancer mortality has been approximately 7.5 and 75/100 000 population, respectively, since the beginning of the last decade. The aim of this study was to evaluate if H. pylori prevalence bears any relationship to gastric cancer mortality rates in these two southern regions of China.
