The National Diabetes Prevention Program in Rural Communities

Not Applicable

Completed

Conditions: Weight Loss
PreDiabetes
Lifestyle Risk Reduction

Interventions: Behavioral: Diabetes Prevention Program-Remote (DPP-R)
Behavioral: Diabetes Prevention Program-Facebook (DPP-FB)

Registration Number: NCT05387434

Lead Sponsor: University of Kansas Medical Center

Brief Summary: The purpose of this pilot trial is to compare feasibility and effectiveness of remote delivery (social media or video conferencing) of the National Diabetes Prevention Program (N-DPP) to adults in rural communities. The research team will train a Kansas State Research and Extension staff to deliver the video conferencing arm while a research team member will lead the social media arm.

Detailed Description: This pilot trial will compare the feasibility and effectiveness of DPP delivered through Facebook (DPP-FB) or group format delivered remotely by Zoom (DPP-R) in adults in rural communities. Both interventions will recruit through the Corporative Extension Service (CES), which serves as the community outreach arm of all land grant universities through over 2,900 offices across the U.S. The Kansas State Research and Extension (KSRE) (Kansas version of CES), is well positioned, but underutilized for the delivery of DPP in rural areas. Delivery of DPP by a well-recognized entity, such as the KSRE, may improve the probability of dissemination and long-term program sustainability. Two CES offices serving rural counties in Kansas will be randomized (1:1) to the DPP-FB or DPP-R arms. Our research team will train one professional staff from KSRE (with backgrounds in nutrition programming and family consumer science) to deliver the DPP-R intervention. A research team member will deliver the DPP-FB intervention. This project will address the following aims:

Primary aim: Compare weight and MVPA between DPP-FB and DPP-R across 6 mos. The investigators expect greater weight loss and MVPA in the DPP-R arm compared with the DPP-FB arm.

Secondary aim: Compare the feasibility of DPP-FB and DPP-R across 6 mos. based on participant retention and program attendance. The investigators expect greater participant retention and program attendance in the DPP-R arm compared with the DPP-FB arm.

Recruitment & Eligibility

Status: COMPLETED

Arm && Interventions

Group	Intervention	Description
DPP-R	Diabetes Prevention Program-Remote (DPP-R)	Weekly 60 min. group meetings, lead by trained KSRE staff, (12-15 participants) will be held by Zoom over 6 months followed by monthly 60 min. group meetings for the later 6 months. Approximately 5 min prior to the meeting time (typically early evening) participants will receive call in information to join the group meeting by video conferencing or phone.
DPP-FB	Diabetes Prevention Program-Facebook (DPP-FB)	Participants will be asked to join a secret, research team moderated, Facebook® group, which is only accessible by group members. The health educator will post the module, de-identified participant self-monitoring data, and comment on individuals posts weekly. Brief discussion prompts are designed to reinforce the primary objectives of each module and to facilitate inter-participant discussion around these topics. Responses will be monitored and tracked. This is analogous to attendance in the Zoom® group.

Primary Outcome Measures

Name	Time	Method
Change in Body Weight From 0-6 Months	Baseline - 6 months	Anthropometric measurements: Body weight will be assessed to the nearest 0.1 kg with a calibrated scale (Belfour Inc., Model #PS6600, Saukville, WI). All participants will be weighed between the hours of 6 and 11 am following a 12 hr. fast in a standard hospital gown.

Secondary Outcome Measures

Name	Time	Method
Participant Retention	6 months	Retention will be defined as attendance at 6 mo. outcome testing.
Average Program Attendance	6 months	Program attendance will be defined as average percentage of sessions attended by group.
