Study to Promote Weight Loss in Primary Care Practices

February 6, 2018 updated by: Ruth Weinstock, State University of New York - Upstate Medical University

Weight Loss in Primary Care: a Translation of the Diabetes Prevention Program

The purpose of this study is to determine if primary care based, telephone-delivered weight loss interventions are effective.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Obesity is related to the rising incidence of type 2 diabetes. Cost-effective interventions leading to sustained weight loss are needed to improve the public health and reverse the alarming rise in diabetes, its cardiovascular complications and other obesity-related illnesses. The Diabetes Prevention Program is identified as a model for a successful weight loss intervention. The proposed study is a randomized controlled trial of 2 active telephone-based interventions based on the Diabetes Prevention Model that will be delivered at primary care sites.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Individual Telephone Intervention
Individually administered weight loss intervention, based on the Diabetes Prevention Program, delivered by telephone in primary care practices.
Behavioral: Individual telephone intervention
Individually administered telephone-based weight loss intervention based on the Diabetes Prevention Program (weekly nurse calls for the first 5 weeks, then monthly, to cover the 16 topics from the Diabetes Prevention Program). In year 1 (after the first 5 weeks), the "coach" will have 3 weekly calls per month with participants. Contact will decrease to monthly in year 2. In year 3 there will be no contact arranged by study staff.
Active Comparator: Group Telephone Intervention
Group education conference calls to deliver the weight loss intervention, based upon the Diabetes Prevention Program, in primary care practices.
Behavioral: Group telephone intervention
Group education conference calls administered weight loss intervention based on the Diabetes Prevention Program (weekly nurse calls for the first 5 weeks, then monthly, to cover the 16 topics from the Diabetes Prevention Program). In year 1 (after the first 5 weeks), the "coach" will have 3 weekly calls per month with participants. Contact will decrease to monthly in year 2. In year 3 there will be no contact arranged by study staff.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Weight
Time Frame: baseline, 1, 2, 3 years
Weight (kg)
baseline, 1, 2, 3 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Blood Pressure
Time Frame: baseline, 1, 2, 3 years
Systolic blood pressure (mm Hg) / Diastolic blood pressure (mm Hg)
baseline, 1, 2, 3 years
Fasting Lipid Panel
Time Frame: baseline, 1, 2, 3 years
LDL-cholesterol (mg/dL)
baseline, 1, 2, 3 years
Fasting Glucose Level
Time Frame: baseline, 1, 2, 3 years
Fasting glucose (mg/dL)
baseline, 1, 2, 3 years
Health Behaviors (Diet, Physical Activity)

baseline, 6 months, 1 and 2 years
International Physical Activity Questionnaire
Time Frame: baseline, 6 months, 1 and 2 years
Measure of physical activity is calculated as in mets/week
