Transmission of Stomach Bacteria Study

Families are Needed For a Study of Transmission of Stomach Bacteria

  • Families with one or more children 6 months to 17 years old
  • We need families with biological children and we need families with adopted children (adopted before age 2 yrs.)

What is involved in the study?

You will be asked to:


  1. Fill out one questionnaire per family. The questionnaire asks about how each family member is related to each other and a couple other questions about each person.
  2. Have each family member provide a stool sample using the provided stool collection kit.
  3. Mail back the questionnaire and small vials of stool sample in a provided pre-paid shipping box.
  • All activities are completed in your own home
  • All study-related materials are sent through the mail
  • Each family will be paid $50 as a thank you for participation

Why is this study being done?

Researchers at Fred Hutch are studying transmission of stomach bacteria within families. The stomach bacteria that we are studying is called Helicobacter pylori. This bacteria infects half the world’s population. For most people who are infected, this bacteria does not cause any problems, but the bacteria can cause ulcers and stomach cancer in some people who are infected. It is not possible to predict who will develop ulcers and stomach cancer as a result of this infection.


Who can participate?

  • Families with one or more children between the ages of 6 months and 17 years
  • Families with biological children and families with children adopted before the age of 2 years
  • Need participation from all family members

Who is not eligible?

  • Families with children adopted after the age of 2 years
  • Families with children adopted by a relative
  • Families with a member who has been treated for Helicobacter pylori within the past 6 months
