Outline of Final Research Achievements |
Adipose tissue is classified into white adipose tissue (WAT), which stores fat, and brown adipose tissue (BAT), which burns fat and generates heat. Beige fat is found to be more easily activated in the morning than in the evening. Based on these findings, methods to activate beige fat in children include exercise in cold environments, wearing light clothing, maintaining a cooler room temperature within a comfortable range, reducing dietary fat intake, consuming fish oil, and implementing programs to ensure adequate sleep for young children. These interventions showed improvements in sleep quality. Additionally, since the activation of BAT/beige fat involves the TRPV1 receptor, we also explored sensory-based nutritional education. Furthermore, we investigated the effects of imeglimin on improving mitochondrial function.

Academic Significance and Societal Importance of the Research Achievements |
褐色脂肪組織(BAT)/ベージュ脂肪の評価法について、FDG-PET/CT法、MRI法、近赤外時間分解分光法、超音波法、赤外線サーモグラフィ法の長所と短所を鑑み小児においては超音波法と赤外線サーモグラフィ法が有用である。今後の小児における褐色脂肪研究に大いに役立つと考えられる。また、褐色脂肪組織(BAT)/ベージュ脂肪を活性化させる、寒冷下での朝の戸外運動、薄着による自然な身体の動き促進、快適な低温の環境での過ごし方、充実した睡眠習慣の獲得を促すプログラムの開発は、小児の肥満や生活習慣病対策に役立つと考えられる。
