About this study

Official title: The Effect of a Behavioral Weight Loss Program With Nutrisystem Meal Provision on Change in Weight, Fasting Blood Glucose, Cholesterol, and Blood Pressure Over 12 Weeks.

The study is to determine the effect of a behavioral weight loss program supplemented with Nutrisystem meal replacements on weight, blood pressure, fasting blood glucose, and blood lipids levels over 12 weeks.

Read the detailed description

Specific Aim 1- Compare two programs, a standard Internet weight loss program and an Internet behavioral weight loss program, enhanced with Nutrisystem meal provision, on their effectiveness in producing weight loss and improvements in fasting blood glucose, blood pressure, and blood lipid levels over 12 weeks.

Specific Aim 2- Determine the usage and acceptability of the two programs.

Overall Hypothesis:

The Internet program with Nutrisystem meal provision will produce greater improvements in participant's health (weight, blood pressure, blood lipids, and fasting blood glucose) than the standard Internet program alone at 12 weeks. The acceptability and usage of each program will directly correlate with weight loss in participants.

Recruitment Methods Participants will be recruited through advertisements in local newspapers. Randomization A two-group randomized design will be used. After meeting all exclusion/inclusion criteria, completion of all study measurements, and provision of written consent, individuals will be randomized to one of the two study groups: (1) the standard Internet behavioral weight loss program alone or (2) the standard Internet program plus Nutrisystem meal provision.

Timeline and Milestones Recruitment advertisements for the study will be placed in mid-December. Participants who meet all inclusion/exclusion criteria will be invited to a study information session the first week of January.

Delivery Phase (Jan.-April 2011) The delivery phase will entail: (1) conducting study information sessions; (2) baseline assessments; (3) conducting the 12-week Intervention; (4) 12-week assessments. Dr. Webber will conduct study information sessions for qualified participants during the first week of January. Interested participants will then be asked to sign consent forms, fill out motivation questionnaires, and to schedule appointments at the Clinical Research Center (CRC) at the University of Kentucky for baseline assessments of height, weight, waist circumference, blood pressure, fasting blood glucose and blood lipids.

Once measurements at the CRC are taken, participants will be randomized to study group. At baseline each group will receive a 2-hour weight loss group session with a registered dietitian. The weight loss session will include presentation of information on exercise and dietary recommendations, an overview of energy balance, and instructions for self-monitoring, good dietary practices, exercise safety recommendations, and orientation to the study website.

Both groups will be given password protected access to a standard Internet program. The website will include 12 weekly lessons based on the Diabetes Prevention Program (DPP), a message board feature, a link to a personal self-monitoring diary, a library of links to diet, exercise, and behavioral resources available on the web, and a weekly weight loss tip. The Nutrisystem group will receive 2 weeks of meals at the baseline 2-hour session. They will be asked to return every two weeks to the clinic to pick up Nutrisystem meals.

Evaluation Phase (May-Oct. 2011) The evaluation phase of the project will entail: (1) data entry, cleaning and analysis; (2) final report preparation; (3) manuscript preparation.

Questions about this trial

What is this clinical trial studying?

A study testing Nutrisystem in people with Obesity, run by University of Kentucky 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 1 inclusion and 1 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 23 Jun 2011. 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?

weight change (time frame: 12 weeks). 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 23 Jun 2011.
