An interventional study of GO-FAR in Prediabetes, sponsored by University of Oklahoma. Recruiting at 1 site in United States. Open to participants aged 18 Years to 39 Years. Per ClinicalTrials.gov, last updated 2026-06-01.
Sponsored by University of Oklahoma · Not applicable, Interventional, and Prevention
This is a single-arm feasibility trial to examine an mHealth intervention that combines high fiber education, home-delivered high fiber foods, and use of continuous glucose monitors.
This is a single-arm trial enrolling young adults (aged 18-39) with prediabetes (based on hemoglobin A1c). Enrolled individuals will complete baseline data collection in person to assess insulin resistance (venous blood samples). Enrolled individuals will then complete a three-month fully-mHealth based intervention focused exclusively on promoting greater fiber intake. Participants will receive weekly home-delivered shipments of high fiber foods and wear a continuous glucose monitor at two time points as a form of biofeedback. After the three months, participants will return for repeat assessment of insulin resistance. After that repeat assessment, participants will do a one-month observation period using cell phone-based ecological momentary assessments.
999 studies on the registry are indexed under Prediabetic State; 238 are open to participants now.
This study's planned enrollment of 80 is above the median of 65 across 844 interventional studies indexed under Prediabetic State.

Exclusion Criteria:
Mobile phone delivered content about fiber (daily), continuous glucose monitors, and home delivered high fiber foods
Behavioral: GO-FAR
3-month intervention combining multiple behavior change techniques (biofeedback, adding objects to the environment, instruction on how to perform the behavior), all focused on helping people at more fiber.
Recruitment (as a measure of intervention feasibility)
Percentage of recruitment goal reached.
Time frame: Evaluated at the end of the project period (2 years in total)
Retention of participants (as a measure of feasibility)
Percentage of enrolled participants who remain in the study throughout the intervention period
Time frame: Retention will be based on time retained in the study over a period of approximately 5 months (from enrollment to completion of follow-up data collection)
Acceptability (as a measure of feasibility)
Participants will rate their perceived acceptability of the intervention using a 5-point Likert scale question ("How would you rate this study intervention as a whole?" rated as Poor, Fair, Good, Very Good, Excellent.
Time frame: Measured at the end of the 3-month intervention
Dietary fiber intake
Measured using the automated self-administered 24-hour recall
Time frame: Baseline, after-intervention (3-months), and after a 4-week observation period
Glycemic control (hemoglobin A1c [HbA1c])
Measured via point-of-care testing devices
Time frame: Baseline and after the intervention (3 months)
Insulin resistance (Homeostatic Model Assessment of Insulin Resistance [HOMA-IR])
Measured via venous blood samples
Time frame: Baseline and after-intervention (3 months)
