This study is testing a mobile health platform to help children get more sleep and prevent obesity. Researchers want to see if different ways of setting sleep goals – either a fixed goal of at least 9 hours per night, or a personalized goal that can be adjusted – are more effective. All participants will receive digital messages with tips for healthy sleep habits, such as managing screen time and bedtime routines. Some will also have virtual study visits. The study is looking for children aged 8-12 who sleep less than 8.5 hours per night and have a body mass index (BMI) between the 50th and 95th percentile. The main goals are to see how much sleep duration changes and how body fat changes over 12 months. The current recruitment status is unclear.

Study design

This is an interventional study that plans to enroll 5000 participants, though the protocol details mention randomizing 325 children. It is a single-site study at the Children's Hospital of Philadelphia (CHOP).

What's involved

You would have clinical measurements taken at CHOP, and your sleep would be measured at home for 12 months using a sleep tracker. This includes a 2-week initial period, 6 months of intervention, and about 5.5 months of follow-up.

Compensation

Not stated in the trial record.

Follow-up

Participants will be followed for approximately 5.5 months after the 6-month intervention period, for a total of 12 months from baseline.
