About this study
The primary aim is to test the effectiveness of an innovative 24-month pragmatic and scalable weight-loss centric approach using a collaborative care model that connects patients with a non-Primary Care Practitioner (PCP) health coach who delivers care remotely to patients through the patient portal of an electronic medical record (EMR).
Read the detailed description
This study is a 24-month, two-arm, parallel controlled trial in a primary care setting. A total of 352 Black adults with obesity and type 2 diabetes or prediabetes will be randomized to either 1) intervention or 2) usual care. The intervention arm will receive a comprehensive, "high-intensity" program, as recommended first-line therapy by the 2013 American Heart Association/American College of Cardiology/The Obesity Society Obesity Guidelines, delivered remotely using eHealth technology, by trained health coaches embedded in the Digital Medicine Group in the Ochsner Health System. The intervention will include remote sessions with the health coach using evidence-based components such as the use of portion control and various behavioral strategies. Patients in the usual care arm will receive their normal, usual care from their primary care team. All patients will participate in the collection of patient-reported outcomes at baseline and approximately 6, 12, and 24 months.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Intensive Lifestyle InterventionBehavioural
Trained health coaches deliver the active intervention - a comprehensive, "high-intensity" program, as recommended first-line therapy by the 2013 American Heart Association/American College of Cardiology/The Obesity Society Guidelines.

What is being measured
The primary outcome is the main question the study is designed to answer.
Body weight (Percent Change)
Body weight is measured in light indoor clothes and is obtained from the electronic medical record.
Measured: Percent (%) Change from Baseline to Month 24
Secondary outcomes (14)
Body weight (kg)
Body weight is measured in light indoor clothes and is obtained from the electronic medical record.
Measured: Change in kg from Baseline to Month 24
Systolic Blood Pressure
Resting systolic blood pressure is measured and is obtained from the electronic medical record.
Measured: Change from Baseline to Month 24
Diastolic Blood Pressure
Resting diastolic blood pressure is measured and is obtained from the electronic medical record.
Measured: Change from Baseline to Month 24
HbA1c
HbA1c levels are assayed and are obtained from the electronic medical record.
Measured: Change from Baseline to Month 24
Total Cholesterol
Total cholesterol levels are assayed and are obtained from the electronic medical record.
Measured: Change from Baseline to Month 24
High-density Lipoprotein (HDL) Cholesterol
HDL cholesterol levels are assayed and are obtained from the electronic medical record.
Measured: Change from Baseline to Month 24
Triglycerides
Triglyceride levels are assayed and are obtained from the electronic medical record.
Measured: Change from Baseline to Month 24
Low-density Lipoprotein (LDL) cholesterol
LDL cholesterol levels are estimated using the Friedewald equation and are obtained from the electronic medical record.
Measured: Change from Baseline to Month 24
Physical Activity
Physical activity is measured using the International Physical Activity Questionnaire-SF questionnaire.
Measured: Change from Baseline to Month 24
Dietary Intake
Dietary intake is measured using National Cancer Institute Dietary Screeners.
Measured: Change from Baseline to Month 24
Impact of Weight on Quality of Life-Lite-Clinical Trials Questionnaire
Items are scored 1-5 (never true to completely true). Scores are obtained on 3 composite scales (Physical, Physical Function, and Psychosocial), as well as total score. The raw composite score is calculated as the average of non-missing responses within each composite, then transforming to a 0-100 scale (worst to best). Composite scores and total score range from 0 to 100, where 100 represents higher levels of functioning.
Measured: Change from Baseline to Month 24
EuroQol-5 Dimension Questionnaire
Each of 5 questions can have a response ranging from 1-5 (none to extreme). These are then concatenated into one of 3125 "health states" (i.e. 11231, 52454, etc.) An EQ-5D summary index is derived by applying a formula that attaches values (weights) to each of the levels in each dimension to create a value set. Lower scores indicate better health.
Measured: Change from Baseline to Month 24
Health Care Utilization Questionnaire
Health care utilization is measured using a brief 4-item questionnaire with continuous responses (how many times did you go to the doctor, go to Emergency Room, stay overnight, # nights). Each question is analyzed separately.
Measured: Change from Baseline to Month 24
Perceived Stress Scale-4 Questionnaire
The Perceived Stress Scale has 4 questions with responses ranging from 0-4 (Never to Very Often). Total (sum) score range is 0-16, with a higher score correlating to more stress.
Measured: Change from Baseline to Month 24

Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Body weight (Percent Change) (time frame: Percent (%) Change from Baseline to Month 24). 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 NCT05523375, 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.
How often is this information updated?
