About this study
Official title: The Effects of Limiting TV Viewing on Diet, Exercise, and Sleep in Overweight and Obese Adults
The specific objectives of this project are to:
- Investigate the effects of reducing TV viewing time on energy intake, eating behavior, and energy expenditure in overweight or obese adult subjects, thus providing a basis for evaluating if reducing TV viewing time might be a useful adjunct therapy in obesity prevention and treatment
- Analyze the types of foods eaten in conjunction with TV viewing
- Determine if there is an association between location of TV and BMI.
- Conditions
- Obesity, Overweight
- Being tested
- No TV viewing reduction, TV viewing reduction
- Medical subject headings
- Obesity, Overweight
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
No TV viewing reductionBehavioural
In the control group, no intervention will be acted upon. This group will receive the exact same protocol as the intervention group, but with observation only.
TV viewing reductionBehavioural
In the experimental arm, TV viewing time will be reduced for half of the study protocol time (3-4 weeks of a 6-8 week protocol).
| Study group | Role | What they receive |
|---|---|---|
| 1 | Experimental | This arm will be experiencing the same protocol as the control group, only their TV viewing time will be reduced. The TV viewing time reduction is the experimental intervention. Receives: Behavioral: TV viewing reduction |
| Control | Active comparator | The control group will be experiencing the exact protocol; only their TV viewing time will not be reduced. Receives: Behavioral: No TV viewing reduction |
What is being measured
The primary outcome is the main question the study is designed to answer.
Energy Intake
Measured: Phase I and Phase II
Secondary outcomes (1)
Energy expenditure
Measured: Phase I and Phase II

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?
Energy Intake (time frame: Phase I and Phase II). 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 NCT00622050, which also lists 2 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.
