Intervention / BehandlungIntervention / Behandlung |
|---|---|
|
Kein Eingriff: Control group
Participants receive standard dietary education and perform passive dietary recording during the 12-week study period.
|
|
|
Experimental: Static goal AI intervention group
Participants receive AI-generated personalized dietary goals that are maintained during the 12-week intervention period.
|
The AI algorithm generates individualized dietary goals based on baseline information.
The generated goals are maintained without dynamic adjustment during the intervention period.
|
|
Experimental: Adaptive goal AI intervention group
Participants receive adaptive AI-based dietary tracking, dynamic goal adjustment, and personalized feedback during the 12-week intervention period.
|
The AI algorithm monitors dietary records and relevant participant information, adjusts dietary goals dynamically, and provides personalized feedback to support dietary behavior change.

Change in Dietary Behavior Score
Zeitfenster: Baseline and 12 weeks
|
Dietary behavior will be assessed using a 12-item dietary behavior questionnaire derived from a 19-item dietary assessment questionnaire developed and routinely used at Seoul National University Hospital Gangnam Center.
Each item is scored on a 3-point scale (1, 3, or 5 points).
Total scores range from 12 to 60, with higher scores indicating healthier dietary behaviors.
The change in total dietary behavior score from baseline to 12 weeks will be evaluated.
