Introduction:
Lifestyle-related diseases represent a significant health cost, highlighting the need to cultivate healthy behaviors, particularly during key developmental periods such as adolescence. This study examines the effectiveness of personalized feedback in promoting sustained healthy eating behaviors in university students, while investigating the role of the frontal pole cortex (FPC) in supporting behavior change and maintenance. Interventions were tailored to individual stages of change using daily food records and dietary analyses. The study aimed to determine whether the FPC is associated with sustained healthy behaviors in the future.
Methods:
We recruited 50 participants (personalized feedback (PF) group: 25, age = 21.44 ± 1.81 years; control feedback group: 25, 21.68 ± 2.68 years). Participants underwent a 28-day intervention including dietary recording, mental health recording (anxiety: STAI), nutrient analysis, and received personalized or control feedback via email. Dietary intake was recorded via a web application and 13 nutrients were analyzed. The PF group received personalized feedback on dietary components and future health risks, whereas the CF group received general feedback on nutritional knowledge. All images acquired using Siemens Prisma (3.0 T) comprised T1w, T2w and diffusion weighted images, processed using HCP pipelines, FreeSurfer and FSL tools for cortical thickness, T1w/T2w ratio and FA data. Image statistics were performed using the PALM toolbox and FSL/Randomise for voxel-wise comparisons, corrected for age and sex. Cortical thickness, T1w/T2w ratio and FA values were extracted using frontal pole masks.
Results:
The results showed significantly more food diary records in the PF group compared to the CF group across feedback cycles received (p = .043). Improvements in calcium, vitamin A, vitamin C and fibre intakes were observed in the PF group (ps < .05). Trait anxiety was significantly reduced in the PF group post-intervention compared to pre-intervention (p < .001). When the relationship between FPC and food diary records was examined, there was a positive correlation in the PF group between greater cortical thickness, T1w/T2w ratio, FA and food diary records (ps < .05).
Conclusions:
Our investigation revealed positive associations between food diary records and cortical thickness, T1w/T2w ratio, and FA, suggesting a correlation between future-oriented behavior and brain structure.
