Healthy Lifestyle
Conditions
Brief summary
The purpose of this study is to determine the processes by which a previously proven lifestyle intervention (the Med-South Lifestyle Program) can most effectively and efficiently be translated into public health and clinical practice to positively impact chronic disease risk reduction among mostly minority, rural, and medically underserved populations.
Detailed description
Purpose: Although lifestyle behavior change interventions are widely recommended to improve health, they are not being implemented sufficiently or equitably on a national scale, particularly in rural communities. The research team has developed and tested multiple lifestyle interventions, which have culminated in the Med-South Lifestyle Program (MSLP), an evidence-based behavior change intervention that translates the PREDIMED (Mediterranean) dietary pattern for a Southeastern US population and includes support for increased physical activity. In this research the investigators propose to identify the most effective and efficient way to scale-up the MSLP for use in public health and clinical practices settings so that it reaches minority, rural, and medically underserved populations. In Phase 1, the investigators will develop, pilot test, and refine implementation strategies that will be used to take the MSLP to scale. Participants: Phase I participants include up to 80 participants who will receive the MSLP and for whom the study team will collect baseline and follow-up data. Procedures (methods): An evidence-based framework for scaling-up health interventions will be used to guide Phase I activities. The initial phase involves refining the scalable unit which includes the lifestyle program (MSLP), implementation strategies for the sites that will give the program, and strategies UNC will use to train sites on implementing the program. To refine the scalable unit the investigators will apply a descriptive, qualitative design to assess the feasibility and acceptability of the MSLP's intervention and implementation strategies (i.e., what the investigators will scale-up in Phases 2 and 3). In Phase 1, the study team will recruit 2 local health departments and 2 federally qualified health centers as participating sites. Each site will form an implementation team of 2-4 individuals who will go through training on intervention delivery and implementation. Sites will be randomized to receive training either through a distance (webinar) or in-person/collaborative format. Each site will recruit up to 20 participants (for a total of 80 across all sites) to receive the intervention.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Eligible Patients Participating | Month 6 | Percentage of each setting's eligible patients who participate in the Med-South Lifestyle Program and the representativeness of participants (age, gender, race/ethnicity) as compared to overall population of eligible patients. |
| Percentage of Med-South Lifestyle Program Delivered as Intended | Month 6 | To determine delivery fidelity, the study team will measure the degree to which the intervention is delivered as intended as assessed by direct observations and audio file reviews documented by checklist. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Mean Change Number of Fruit and Vegetable Servings Per Day | Baseline, Month 6 | The mean difference in fruit and vegetable servings per day (baseline servings/day - follow-up servings/day) as measured by the Block Fruit-Vegetable-Fiber Screener. The Block Fruit-Vegetable-Fiber Screener is a 10-item scale with responses ranging from: (1) Less than 1/week to (5) 2+ a day. Higher scores reflect a better outcome. |
| Mean Change in Minutes of Physical Activity Per Week | Baseline, Month 6 | Mean difference in minutes of physical activity per week (baseline activity in minutes/week - follow-up activity in minutes/week) as measured by the validated modified RESIDE questionnaire. The RESIDE questionnaire is a 21-item self-administered instrument in which participants recall the frequency, duration, and destination of their walking (for transport and recreation) within and outside of their neighborhood, and cycling activity in a usual week. Higher scores indicate more minutes of activity. |
| Mean Percent Change in Weight | Baseline, Month 6 | Mean weight change (in kg) from baseline to follow-up expressed as a percentage. |
