Effectiveness of an Agentic AI-Based Personalized Dietary Management Algorithm in Health Screening Participants: A Randomized Controlled Trial
This randomized controlled trial aims to evaluate the effectiveness of an Agentic AI-based personalized dietary management algorithm among adults undergoing health screening.
Participants will be assigned to a control group, a static goal AI intervention group, or an adaptive goal AI intervention group and followed for 12 weeks.

Detaljerad beskrivning
This study is a randomized controlled trial designed to evaluate whether an Agentic AI-based personalized dietary management algorithm improves dietary behavior and metabolic health indicators among adults undergoing health screening.
Eligible participants will be randomly assigned to one of three groups: standard dietary education and passive dietary recording, AI-generated personalized dietary goals maintained throughout the study period, or adaptive AI-based dietary tracking with dynamic goal adjustment and personalized feedback.
Outcomes will be assessed at baseline and after 12 weeks, including dietary evaluation index scores and metabolic health-related clinical indicators.

Deltagargrupp / Arm |
Intervention / Behandling |
|---|---|
|
Inget ingripande: Control group
Participants receive standard dietary education and perform passive dietary recording during the 12-week study period.
|
|
|
Experimentell: 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.
|
|
Experimentell: 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
Tidsram: 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.
