About this study

The purpose of this study is to determine if providing free-of-charge access to a group-based lifestyle intervention delivered in partnership with the community is cost-effective for the prevention of type 2 diabetes.

Read the detailed description

Randomized controlled trials have shown that modest lifestyle changes can prevent or delay the onset of diabetes in adults with pre-diabetes. Unfortunately, despite the increasing prevalence of pre-diabetes and diabetes in all facets of the population, intervention programs needed to achieve these goals are costly and remain unavailable in most clinical settings. Over the past 3 years, we have demonstrated the feasibility of training community instructors to deliver a group-based adaptation of the Diabetes Prevention Program (DPP) lifestyle intervention. In this pilot research, this new delivery model achieves a level of weight reduction that was associated with diabetes prevention and improved cardiometabolic risk factor control in the DPP. This new, large-scale randomized effectiveness trial is designed to evaluate the costs and effectiveness of a partnered approach to identify adults with pre-diabetes in primary care settings, deliver brief advice for diabetes prevention, and provide access to a group-based adaptation of the DPP lifestyle intervention offered by the community. This study will compare costs and outcomes to a standard care, brief clinical counseling approach delivered by Registered Dietitians.

Questions about this trial

What is this clinical trial studying?

A study testing Dietitian Counseling Alone and Dietitian Plus Community Group Lifestyle in people with Hyperglycemia and Obesity, run by Northwestern University 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 3 inclusion and 12 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: finished, as of the sponsor's last update on 29 Mar 2018. 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?

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?

% Change in Body 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 29 Mar 2018.
