About this study

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.

Read the 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.

Conditions: PreDiabetes, Weight Loss, Lifestyle Risk Reduction
Being tested: Diabetes Prevention Program-Remote (DPP-R), Diabetes Prevention Program-Facebook (DPP-FB)
Medical subject headings: Prediabetic State, Weight Loss, Risk Reduction Behavior

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Diabetes Prevention Program-Remote (DPP-R)Behavioural
The DPP is an evidenced based lifestyle intervention that includes topics on nutrition and physical activity delivered over Zoom.
Diabetes Prevention Program-Facebook (DPP-FB)Behavioural
The DPP is an evidenced based lifestyle intervention that includes topics on nutrition and physical activity delivered over Facebook.

Study groups in NCT05387434
Study group	Role	What they receive
DPP-R	Experimental	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. Receives: Behavioral: Diabetes Prevention Program-Remote (DPP-R)
DPP-FB	Experimental	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. Receives: Behavioral: Diabetes Prevention Program-Facebook (DPP-FB)

What is being measured

The primary outcome is the main question the study is designed to answer.

Change in Body Weight From 0-6 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.
Measured: Baseline - 6 months

Secondary outcomes (2)

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

Study design

Study type: Interventional
Phase: Phase N/A
Primary purpose: Prevention
Allocation: Randomised
Intervention model: Parallel groups
Model description: The proposed 2-arm trial will compare the feasibility and effectiveness of Facebook or remote-delivery of the DPP in rural adults with prediabetes both delivered through the KSRE. The CES is a non-formal educational program, implemented in the U.S. through each state's designated land grant university, to help people use research-based knowledge to improve their lives. The KSRE maintains local units which are comprised of single counties or multi-county districts. Two KSRE local units serving rural counties will be identified by our partners at KSRE and randomized to the Facebook or remote delivery arms. Members of the KUMC research team will recruit and consent participants and will train KSRE personnel to deliver the 30 core-sessions of the DPP protocol over 12 mos. Outcomes will be assessed by the research team at the local CES offices at baseline, 3 mos. 6 mos. and 12 mos.

What does the primary outcome measure?

Change in Body Weight From 0-6 Months (time frame: Baseline - 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05387434, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
