Assessing the Gut Microbiota & Individual Diet (ABID) Study

Abid' is the Navajo word for stomach.

The Navajo ABID Study is a multi-phase research project aimed at studying risk factors for stomach cancer in Navajo (Diné) people.

The ABID study is currently in its second phase. 

The strongest risk factor for stomach cancer is infection with Helicobacter pylori (H. pylori)

What is H. pylori?

  • Helicobacter pylori (H. pylori) is a bacteria known to infect the stomach.

  • People can get an H. pylori infection from a person who is infected or by consuming contaminated water or food.

  • Most people with an H. pylori infection will feel no symptoms. However, people who have symptoms can experience stomach pain, heartburn, weight loss, or changes in the stool. 


H. pylori is the focus of the
Navajo ABID Study  

Because H. pylori is known to be a risk factor in developing stomach cancer, H. pylori is the focus of the Navajo ABID study. Conducting research on H. pylori stomach infections can tell us how to identify and support cancer prevention strategies to reduce the burden of stomach cancer in the Navajo people.

The Diné (Navajo) Nation

The Navajo Nation spans three states - northwest New Mexico, most of northeastern Arizona, and southern Utah. The Navajo Nation has been recognized as a sovereign nation since 1868, but has resided in the Southwest since time immemorial.
