About this study
Official title: Managing Obesity by Leveraging Health Information Technology to Lower Cancer Risk
The study aims to randomize 250 participants to 1 of 2 arms: a.) an Active Intervention Group (based on the Look AHEAD* ILI) or b.) a Comparison Group (based on the Look AHEAD DSE Comparison group) to test the hypothesis that a multicomponent, multilevel behavioral weight loss intervention (Active Intervention Group) adapted for different population groups and delivered through Health Information Technology (Health IT) tools via the Electronic Health Record (EHR) patient portal, will result in significantly greater weight loss 12 months after enrollment compared to the Comparison Group.
*The Look AHEAD study was a multi-center, randomized clinical trial involving overweight and obese persons with type 2 diabetes, aimed to determine the effects on the cardiovascular outcomes of an intensive lifestyle intervention (ILI) for weight loss, in comparison to the diabetes support and education intervention (DSE).
Read the detailed description
This project tests whether the adapted Look AHEAD Intensive Lifestyle Intervention (ILI) will result in significant weight loss when delivered through Health IT - EHR patient portal compared to a Comparison group (based on Look AHEAD DSE Comparison group). This project will be conducted in 2 stages: a formative assessment stage (Stage 1) and a clinical trial stage (Stage 2).
During Stage 1, we will modify the interactive technology-based Look AHEAD ILI that we already developed for the TARGIT study (Active Intervention group). We will also adapt the Look AHEAD Comparison condition (DSE group) for our Comparison condition. We will also optimize the protocol for acceptability in different populations and in a rural setting.
During Stage 2, we will randomly assign 250 participants to either the Comparison Group or the Active Intervention Group to address the primary aim of testing the hypothesis that a multicomponent, behavioral weight loss intervention delivered through Health IT - patient portal will lead to significantly greater weight loss 12 months after enrollment in the Active Intervention group compared with the Comparison group. Our Health IT-based intervention is potentially cost-effective and thus disseminable to any practice-based physician group with access to an EHR with a patient portal.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Active Intervention GroupBehavioural
Also called Weight Loss, Adapted Look AHEAD ILI Group
The 3 major intervention components are diet, physical activity, and the behavioral modification curriculum. Scheduled interactions are educational podcasts (a series of audiovisual, digital media files) paired with a follow-up phone counseling session with a trained behavioral interventionist. A patient portal message will be sent to participants when a new podcast is posted. Interactive sessions will be weekly (weeks 1-16), biweekly (weeks 17-24), and monthly (weeks 25-52). The goal for weight loss is ≥ 7% of initial weight over the course of 12 months. Participants will restrict caloric intake with the goal of 1,200-1,500 kcal/day for those weighing < 114 kg and 1,500-1,800 kcal/day for those weighing ≥ 114 kg. The physical activity goal will be for participants to gradually increase to 175-200 minutes of moderate-intensity activity per week by the 24th week. Participants will also be asked to self-monitor their dietary intake and physical activity using the "Lose It!" app.
Comparison GroupBehavioural
Also called Adapted Look AHEAD DSE Group
All participants in the Comparison Group will receive a mandatory 13 contacts per year including 3 informational sessions on nutrition, physical activity and social support and 10 contacts via patient portal or email regarding intervention topics. The Look AHEAD Comparison Group was designed to be realistic, achievable, and an acceptable intervention that encouraged optimal study retention.
| Study group | Role | What they receive |
|---|---|---|
| Active Intervention Group | Experimental | Look AHEAD Intervention program adapted for delivery via Health IT modified for cultural and social norms applicable to different population groups Receives: Behavioral: Active Intervention Group |
| Comparison Group | Active comparator | Look AHEAD DSE (Diabetes Support and Education) Comparison Group intervention adapted to be delivered via the EHR patient portal with telephonic support Receives: Behavioral: Comparison Group |
What is being measured
The primary outcome is the main question the study is designed to answer.
Relative percentage change in weight
This is calculated for each follow-up visit as ((weight at FU visit - baseline weight) / (baseline weight)) × 100%.
Measured: 12 months
Secondary outcomes (3)
Relationship of mutlitlevel determinants of health (screening tool) with weight change over time
How multilevel determinants of health, assessed via the Social Needs Screening Tool, relate to patient success with weight loss
Measured: 12 months
Relationship of mutlilevel determinants of health (BRFSS) with weight change over time
How multilevel determinants of health, assessed via the Social Determinants of Health Questions Adapted from the Behavioral Risk Factor Surveillance System (BRFSS) 2017 Questionnaire, relate to patient success with weight loss
Measured: 12 months
Relationship of multilevel determinants of health (z codes) with weight change over time
How multilevel determinants of health, assessed using z codes for Social Determinants of Health constructs abstracted from the Electronic Health Record using ICD -10 codes, relate to patient success with weight loss
Measured: 12 months

- This is a 2-arm, parallel, randomized, controlled clinical trial. Eligible participants will be randomly assigned in a 1:1 ratio to either a behavioral weight loss intervention group delivered via Health IT with telephonic support (Active Intervention Group) or the Comparison Group. Because intervention delivery does not depend on clinic site, the study team has opted for a more powerful individual randomization over cluster randomization (but the team will potentially include clinic site as a grouping effect in the analysis).

Questions about this trial
What is this clinical trial studying?
A study testing Active Intervention Group and Comparison Group in people with Weight Loss and Overweight and Obesity, run by University of Tennessee at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 20 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Relative percentage change in weight (time frame: 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Nov 2025; AzTrials last refreshed its copy on 8 Nov 2026.
