Navajo ABID Study: Phase I
2019 - 2022
Phase I aimed to recruit 150 adult participants from two geographic areas on the Navajo Nation- the Northern Navajo Agency and the Fort Defiance Agency. Combined, these areas represent just over 40% of the Navajo Nation population.
Who participated in Phase I?
Phase I Conclusions
Over half of study participants were infected with H. pylori.
Over three-fourths of participants were infected with an H. pylori cag-A strain type. Thus, a large proportion of H. pylori cases had a H. pylori strain type that can deliver cag-A proteins into stomach cells to interrupt cell activity, increase immune response, and increase disease severity.
Participants who reported having H. pylori in the past had a lower chance of having H. pylori during the study.
Participants with a high consumption of Soups and Mixed dishes diet had a higher chance of H. pylori infection compared to participants with low consumption.
