Engaging Tribal Policy Makers to Improve the Food and Physical Activity Environments in American Indian Communities

The investigators plan to accomplish this objective by developing, implementing, and
evaluating a randomized controlled trial of an intervention to improve diet and physical
activity-related risk factors of obesity. A previous iteration of the intervention trial,
called Obesity Prevention Research and Evaluation of InterVention Effectiveness in NaTive
North Americans (OPREVENT) was implemented in five American Indian communities in Michigan
and New Mexico. OPREVENT was a multi-level, multi-component intervention functioning at the
community, institution, household, and individual levels and was implemented in schools, food
stores, and worksites. Prior to OPREVENT, the research team has run multi-level interventions
by working with schools and food stores in Native North American (NNA) communities1-6. For
this new trial, named OPREVENT2, the research team will expand on the collective experience
working on obesity prevention interventions in American Indian (AI) settings by developing
complementary policy and social media components to support long-term sustainability of the
OPREVENT intervention. OPREVENT2 will be implemented in six new AI communities.

Inclusion Criteria:

- With the exception of the school intervention, which will only include teachers of
grades 2-6 and students in grades 2-6 (ages 6-13), all community members will be
included in the intervention.

Gender, Age and Locale

- The investigators will work with male and female schoolchildren and adults, aged 6-13
and 18-75 years who live in one of the participating tribal communities.

Exclusion Criteria:

- No adult community members will be excluded from the intervention as they are
"passive" media and environmental changes, and available to everyone.
