Lifestyle-related diseases remain a significant public health concern, highlighting the need to promote sustained health behaviors, particularly among young adults. The present study examines the role of the frontal pole cortex (FPC)-known for supporting persistence towards near-term goals-in promoting long-term health behavior change. Fifty participants were engaged over a 27-day period, during which they maintained daily food diaries. Participants were divided into two groups: one receiving Personalized Feedback (PF) tailored to individual dietary habits and another receiving Control Feedback (CF) involving general nutritional information. The PF group demonstrated higher engagement in diary completion, improved nutritional intake, and better mental health marked by a significant reduction in trait anxiety compared to the CF group. Notably, a distinct correlation between FPC structural features-cortical thickness, T1-weighted/T2-weighted ratio, and fractional anisotropy-and the frequency of diary loggings was observed exclusively in the CF group. This finding suggests that the structural prosperity of the FPC is associated with engagement levels without the modulation effects of personalized feedback. These outcomes highlight the potential of personalized feedback to utilize FPC-related mechanisms for enhancing long-term dietary habits, emphasizing the importance of considering neurobiological traits in health behavior interventions.
与生活方式相关的疾病仍然是一个重大的公共卫生问题，这凸显了促进持续健康行为的必要性，尤其是在年轻人当中。本研究探讨了以支持对近期目标的坚持而闻名的额极皮层（FPC）在促进长期健康行为改变中的作用。50名参与者在27天的时间里参与研究，在此期间他们每天记录饮食日记。参与者被分为两组：一组接受根据个人饮食习惯量身定制的个性化反馈（PF），另一组接受包含一般营养信息的对照反馈（CF）。与CF组相比，PF组在日记填写方面的参与度更高，营养摄入得到改善，心理健康状况更好，特质焦虑显著降低。值得注意的是，仅在CF组中观察到FPC结构特征——皮质厚度、T1加权/T2加权比率和分数各向异性——与日记记录频率之间存在明显的相关性。这一发现表明，FPC的结构健全与参与程度相关，而不受个性化反馈的调节作用影响。这些结果凸显了个性化反馈利用与FPC相关的机制来改善长期饮食习惯的潜力，强调了在健康行为干预中考虑神经生物学特征的重要性。
