Diet, Healthy, Physical Activity
Conditions
Brief summary
Deep South Native Americans disparately suffer from diabetes, hypertension, and obesity with only 5-10% of Native Americans living past age 65 compared to 15-17% of Whites. Standard lifestyle interventions to improve diet and physical activity behaviors have shown improvement in weight and other cardiometabolic outcomes among Native Americans. The impact of lifestyle interventions on preventable chronic diseases among Native Americans is limited by the exclusion of a multi-level approach with cultural and social enhancements that address the spiritual and social domains of physical health. Therefore, there is an urgent need to determine how spiritual and social domains of health at individual and family levels may advance lifestyle management interventions.
Detailed description
The overall objective for this study is to determine the effectiveness of a more holistic intervention targeting the individual and family levels to enhance health outcomes and program engagement among Native Americans in the Deep South compared to standard approaches. Our central hypothesis is that the integration of spiritual and social domains of health into the standard lifestyle intervention approach will significantly improve attendance, retention, and cardiometabolic profiles of Deep South Native Americans. This hypothesis is supported by our own preliminary data that health behaviors of Deep South Native Americans are fostered by family support and hindered by fatalistic attitudes. The rationale that underlies the proposed research is that demonstration of the feasibility and effectiveness of an intervention that integrates spiritual and social domains will provide new opportunities for its continued development as a strategy to improve disease management/prevention best practices in Deep South Native Americans. The specific aims for the study are to develop a conceptual model to define spiritual factors and spiritually- and socially-enhanced intervention components that could advance lifestyle management interventions among Native Americans in the Deep South and to determine feasibility of lifestyle intervention components and study instruments among Native Americans in the Deep South. The plan is to to pilot recruitment methods, standard lifestyle intervention components, and implementation protocol and procedures to assess acceptability, optimize population engagement, and improve fidelity of delivery.
Interventions
BEHAVIORALBehavioral Treatment
The theoretical framework for the Move & Eat 2 Live intervention is guided by the health belief model (HBM), socioecological model (SEM) and motivational interviewing (MI) approach. Tailoring to the target community will include a standard cultural adaptation that will replace curriculum content and examples with Native American relevant foods, physical activities, and representation in materials. For this study, the intervention will be piloted in the target population and will include the first 5 sessions of the original 12-session program.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Program engagement | From first intervention session to the final (5th) intervention session at 10 weeks | Program engagement will be measured by session attendance and program retention. Session attendance will be captured by the percentage of participants that attend each session. Retention will be examined based on three intervals. Interest retention will include the number of participants who completed the interest form versus those who expressed interest but did not complete the interest form, enrollment retention will include the number of participants who enrolled versus expressed interest but did not enroll, baseline retention will include number of participants who completed baseline data collection versus those who enrolled but did not complete baseline data collection. |
| Implementation fidelity | from first intervention session to the final (5th) intervention session at 10 weeks | To examine implementation fidelity, the initial four sessions will be randomly selected for in vivo observation by the primary investigator, co-investigators, and/or research staff. The assessment will be guided by a checklist that includes session information (time, place, session length, etc.), session components, and allows for account of session deviations, etc. |
