Outline of Final Research Achievements

A prospective study of lifestyle and health was conducted in children aged 6 to 15 years. During the study period 2021-2023, about 1800 children in each of grades 4, 7, and 9 participated in the surveys, including a lifestyle questionnaire and medical check-ups. The intakes of nutrients, food groups, isoflavones, carbohydrate composition, glycemic index, and glycemic load were estimated from food frequency questionnaires. The associations between diet and other lifestyle factors and height, weight, waist circumference, blood pressure, glucose tolerance, lipid metabolism, and pubertal status were examined. In addition, the impact of school closures due to the COVID-19 pandemic on children's lifestyle and health was investigated.

Academic Significance and Societal Importance of the Research Achievements

小学1年生から中学3年生までを縦断的に追跡し、生活習慣や身体指標を評価した研究は少ない。特に、小児期の様々な栄養摂取量を推定し健康状態との関連を評価することで、小児期の食事の摂取がどうあるべきかを示唆し、食育につなげることができる。また、2020年のコロナ禍における学校一斉休校が子ども達の生活習慣や健康に与えた影響を調べることは、将来の健康危機における学校のあり方に示唆を与える。
