Promoting Successful Weight Loss in Primary Care in Louisiana Using Information Technology
- Conditions
- Diabetes Mellitus, Type 2PreDiabetesObesity
- Interventions
- Behavioral: Intensive Lifestyle Intervention
- Registration Number
- NCT05523375
- Lead Sponsor
- Pennington Biomedical Research Center
- Brief Summary
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).
- 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.

Group Intervention Description Intensive Lifestyle Intervention Intensive Lifestyle Intervention The intervention arm receives 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 includes remote sessions with the health coach using evidence-based components such as the use of portion control and various behavioral strategies .Patients in the Intervention arm attend weekly sessions in the first six months, followed by monthly sessions for the remaining 18 months.
- Primary Outcome Measures
Name Time Method Body weight (Percent Change) Percent (%) Change from Baseline to Month 24 Body weight is measured in light indoor clothes and is obtained from the electronic medical record.
- Secondary Outcome Measures
Name Time Method HbA1c Change from Baseline to Month 24 HbA1c levels are assayed and are obtained from the electronic medical record.
Triglycerides Change from Baseline to Month 24 Triglyceride levels are assayed and are obtained from the electronic medical record.
Low-density Lipoprotein (LDL) cholesterol Change from Baseline to Month 24 LDL cholesterol levels are estimated using the Friedewald equation and are obtained from the electronic medical record.
Physical Activity Change from Baseline to Month 24 Physical activity is measured using the International Physical Activity Questionnaire-SF questionnaire.
Dietary Intake Change from Baseline to Month 24 Dietary intake is measured using National Cancer Institute Dietary Screeners.
Body weight (kg) Change in kg from Baseline to Month 24 Body weight is measured in light indoor clothes and is obtained from the electronic medical record.
Total Cholesterol Change from Baseline to Month 24 Total cholesterol levels are assayed and are obtained from the electronic medical record.
High-density Lipoprotein (HDL) Cholesterol Change from Baseline to Month 24 HDL cholesterol levels are assayed and are obtained from the electronic medical record.
Systolic Blood Pressure Change from Baseline to Month 24 Resting systolic blood pressure is measured and is obtained from the electronic medical record.
Diastolic Blood Pressure Change from Baseline to Month 24 Resting diastolic blood pressure is measured and is obtained from the electronic medical record.
Impact of Weight on Quality of Life-Lite-Clinical Trials Questionnaire Change from Baseline to Month 24 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.
EuroQol-5 Dimension Questionnaire Change from Baseline to Month 24 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.
Health Care Utilization Questionnaire Change from Baseline to Month 24 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.
Perceived Stress Scale-4 Questionnaire Change from Baseline to Month 24 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.
