Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The overall objective of the study is to reduce adult obesity in participating American Indian (AI) communities and to improve understanding of the behavioral and environmental factors affecting obesity in these settings.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Participants

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Intervention

The intervention is a multi-level, multi-component intervention designed to increase access to and consumption of healthier foods in Native American Communities. Intervention components will occur at the policy level; food retail outlet level; neighborhood level- schools and worksites, and household level.

Group Type EXPERIMENTAL

Intervention

Intervention Type BEHAVIORAL

Intervention components will occur at the policy level (working with tribal leaders makers to sustain intervention components; food retail outlet level (working with grocery stores and owners to stock, promote, and sell healthier foods and beverages); neighborhood level (working with worksites and schools to deliver nutrition intervention sessions to youth and adults in intervention neighborhoods); household level (providing a social media program that provides parents and caregivers tips for healthier eating).

Control

Similar to many community- based public health research programs, the control arm will not receive any intervention components during the initial intervention period. However, after all assessments are completed they will receive a 'delayed intervention' protocol, where the community receives the intervention elements as described in the intervention arm after assessment measures have been completed.

Group Type NO_INTERVENTION
