简要总结
This study will test the validity and feasibility of an smartwatch-based system to detect eating and drinking events in both laboratory and free-living conditions.
详细描述
The study will: 1) determine whether the smartwatch-based system accurately detects eating events in child-parent dyads in controlled settings and 2) evaluate the feasibility and practicality of passively detecting eating events in child-parent dyads over 3 days in free-living settings. The study will include two phases. During the laboratory visit, child-parent dyads will wear the smartwatch on their dominant hand and perform activities including eating gestures. These activities will be recorded with a video camera, and the videos will be coded for the ground truth times of eating. In the second phase of the study, child-parent dyads will continue wearing the smartwatch for 3 more days in free-living conditions. In the free-living period, parents will receive personalized Ecological Momentary Assessment (EMA) prompts reminding them to activate the smartwatch.

结局指标
主要结局
Accuracy and Performance of Smartwatch-based Eating Detection System in Controlled Conditions
时间窗: During the controlled laboratory session (Day 1).
Accuracy and performance of smartwatch-based system for detecting eating and drinking events compared to video-coded ground truth during a controlled laboratory conditions. Metrics include: Precision (proportion of correctly detected eating events among all detected events), Recall/Sensitivity (proportion of actual eating events detected), Specificity (proportion of non-eating events correctly identified as non-eating) F1-score (harmonic mean of precision and recall), Overall accuracy (proportion of correct classification).
Adherence to Smartwatch Protocol
时间窗: During the free-living phase (Days 2-4).
Proportion of families meeting adherence criteria, defined as both parent and child wearing the smartwatch during eating on at least 2 of 3 days and the parent responding to ≥75% of EMA prompts related to smartwatch charging and app functionality.
