Project REST: Understanding Sleep and Eating in Children

This study, called Project REST, is looking at how sleep affects eating habits and weight in children aged 8 to 12 years old. We know that being overweight or obese and not getting enough sleep are common health concerns for kids. This study wants to understand how sleep restriction (sleeping 8 hours) and sleep extension (sleeping 11 hours) for one week impact weight and eating behaviors. You might be able to join if you are 8-12 years old, at risk for obesity (BMI at or above the 85th percentile for your age and sex, or at or above the 50th percentile with an obese parent), and usually sleep between 9.5 and 10.5 hours per night. The study will measure changes in weight and eating behavior after 4 weeks. The current status of this study is unclear.

Study design
This is an interventional study, meaning participants will receive specific behavioral interventions. It aims to enroll 120 children.
What's involved
Participants will be asked to restrict their time in bed to 8 hours for one week and extend their time in bed to 11 hours for another week.
Compensation
Not stated in the trial record.
Follow-up
Changes in weight and eating behavior will be measured at 4 weeks after the interventions.
