Agentic AI Personalized Dietary Management Study (AIDiet)

4. juni 2026 opdateret af: Su-Yeon Choi, Seoul National University Hospital

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.

Studieoversigt

Detaljeret beskrivelse

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.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Ingen indgriben: Control group
Participants receive standard dietary education and perform passive dietary recording during the 12-week study period.
Eksperimentel: 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.
Eksperimentel: 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.

Tidsramme
Change in Dietary Behavior Score
Tidsramme: 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. unit:score
Baseline and 12 weeks
Outcome Measure: Change in Client Satisfaction Questionnaire Score (CSQ-8)
Tidsramme: from baseline to 12 weeks.
Participant satisfaction with the system will be assessed using the Client Satisfaction Questionnaire-8 (CSQ-8). Total scores range from 8 to 32, with higher scores indicating greater satisfaction with the system.unit:score
from baseline to 12 weeks.
Change in System Usability Scale Score (SUS)
Tidsramme: from baseline to 12 weeks
System usability will be assessed using the System Usability Scale (SUS). Total scores range from 0 to 100, with higher scores indicating better usability. unit:score
