Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.

Summary

This study tests whether a smartwatch can automatically detect eating and drinking events in parents and children aged 8-12. Participants wear the watch during a lab session and for three days at home. The goal is to see how accurate the watch is compared to video recordings and parent reports. If it works, it could make studying eating behaviors much easier.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could lead to a simple way to track eating habits automatically, helping researchers understand eating behaviors without manual logging.
What could go wrong
This is a small, early-stage feasibility study (35 families) focused on accuracy, not health outcomes. The smartwatch may not work well in real-world conditions or for all families.
