Rural Lifestyle Intervention Treatment Effectiveness Trial
A study testing lifestyle intervention in people with Obesity, run by University of Florida at 8 sites in United States.
Trial summary
More and more Americans are becoming overweight. The rates of overweight are especially high in rural areas of the country. Until now, there has been little access to weight management programs in rural areas. This study will examine ways to help individuals from rural counties to manage weight and improve fitness.

About this study
More and more Americans are becoming overweight. The rates of overweight are especially high in rural areas of the country. Until now, there has been little access to weight management programs in rural areas. This study will examine ways to help individuals from rural counties to manage weight and improve fitness. To do this, three doses of lifestyle treatment (Low, Moderate and High)will be compared to an education control condition. Our principal hypothesis is that both the Moderate and High conditions will have greater weight loss at two years than either the Low or Control conditions.
Read the detailed description
Higher rates of obesity, sedentary lifestyle, and coronary heart disease are observed in rural than in non-rural areas of the U.S., yet the treatment of obesity in the rural population has received little attention. Efficacy trials, conducted in academic health centers, show that lifestyle interventions can produce sufficient weight reductions to improve health, but very few trials have been carried out in medically underserved community settings. Moreover, the high intensity of treatments used in efficacy studies represents a barrier to dissemination into rural settings. The existing infrastructure of the United States Department of Agriculture Cooperative Extension Service, with over 2900 offices nationwide, may serve as a valuable resource for bringing lifestyle interventions to rural areas. Preliminary data from our rural obesity research program show promising findings for lifestyle interventions delivered through Extension offices. The next logical step in this line of research is to determine the minimum intensity of treatment required to produce clinically meaningful, long-term weight reductions. We propose to conduct a single-blind, multi-site, randomized controlled trial in obese adults (N=542) to evaluate the effects of LOW, MODERATE, and HIGH doses of lifestyle treatment on two-year changes in body weight, compared to an education CONTROL condition. The LOW intensity condition reflects the dose of group treatment commonly used in community settings, whereas the HIGH dose corresponds to the intensity level employed in efficacy trials. The MODERATE intensity intervention represents a treatment dose that our preliminary data suggest may provide benefits comparable to the HIGH intensity intervention. Our principal hypothesis is that both the MODERATE and HIGH interventions will produce greater weight reductions at two years than either the LOW or CONTROL conditions. We will also evaluate the proportion of participants in each condition, who achieve clinically significant weight losses, and we will examine changes in metabolic risk factors, dietary intake, physical activity, and quality of life. We will calculate the cost-effectiveness of the interventions, and we will investigate potential mediators of long-term change.

Questions about this trial
What is this clinical trial studying?
A study testing lifestyle intervention in people with Obesity, run by University of Florida at 8 sites 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 2 inclusion and 4 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 5 Apr 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 8 sites 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?
body weight (time frame: two years). 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 NCT00912652, which also lists 3 linked publications.
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 5 Apr 2018.
