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.",[13],{"name":14,"affiliation":5,"role":15},"Hanim E Diktas, PhD","PRINCIPAL_INVESTIGATOR",[17],{"name":14,"role":18,"phone":19,"phoneExt":7,"email":20},"CONTACT","(225) 763-2832","hanim.diktas@pbrc.edu",[22],{"facility":5,"status":23,"city":24,"state":25,"zip":26,"country":27,"countryCode":28,"cosmosGeoPoint":29,"geoPoint":34,"contacts":35},"RECRUITING","Baton Rouge","Louisiana","70808","United States","US",{"type":30,"coordinates":31},"Point",[32,33],-91.18747,30.44332,{"lat":33,"lon":32},[36],{"name":14,"role":18,"phone":7,"phoneExt":7,"email":7},{"type":15,"investigatorFullName":38,"investigatorTitle":39,"investigatorAffiliation":5,"oldNameTitle":7,"oldOrganization":7},"Hanim Diktas","Principal Investigator","100615251","evaluating-the-validity-and-feasibility-of-a-smartwatch-based-eating-detection-system-to-passively-and-automatically-detect-eating-events-in-child-parent-dyads-100615251",false,"NCT07290179","Evaluating the Validity and Feasibility of a Smartwatch-based Eating Detection System to Passively and Automatically Detect Eating Events in Child-parent Dyads","Inclusion Criteria:\n\n* Parents or caregivers (18-70 years) who have children aged 8-12 years\n* Child is willing and able to wear smartwatch during school hours (have not restrictions in the school setting)\n\nExclusion Criteria:\n\n* Any condition or circumstance that could impede study completion\n* Child does not follow a regular eating pattern\n* Child eats less than 1 meal and 1 snack in a day\n* Child is restricted or allergic to the study foods\n* Refusal or unable to use the smartwatch to collect data for the 3-day period in free - living conditions\n* Parental refusal or unable to respond Ecological Momentary Assessment prompts",true,"ALL","8 Years","12 Years",{"count":51,"type":52},35,"ESTIMATED","OBSERVATIONAL","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.",[56],"Eating Behavior","2026-06-10",{"date":59,"type":60},"2026-06-11","ACTUAL",{"date":57,"type":60},{"date":63,"type":52},"2026-12",{"name":5,"class":6},1]
