Conditions
Summary

Eligibility
Inclusion Criteria2
- Parents or caregivers (18-70 years) who have children aged 8-12 years
- Child is willing and able to wear smartwatch during school hours (have not restrictions in the school setting)
Exclusion Criteria6
- Any condition or circumstance that could impede study completion
- Child does not follow a regular eating pattern
- Child eats less than 1 meal and 1 snack in a day
- Child is restricted or allergic to the study foods
- Refusal or unable to use the smartwatch to collect data for the 3-day period in free - living conditions
- Parental refusal or unable to respond Ecological Momentary Assessment prompts

Interventions
Participants (child-parent dyads) will wear a smartwatch on their dominant hand during a laboratory session and for three days in free-living conditions. In the lab, dyads will perform eating-related activities (e.g., eating with utensils, eating with hands, drinking) and non-eating activities (e.g., walking, writing, brushing teeth) while being video recorded for ground truth validation. Parents will receive a 20-minute training on using Ecological Momentary Assessment (EMA) prompts to record meal and snack times and will respond to EMA reminders during the free-living period. Adherence will be monitored through smartwatch wear time and EMA response rates.
