運動習慣が小学生と中学生の体組成と骨密度に及ぼす影響と 親子の運動習慣の関係；青森県内の3つの町における調査 Effects of exercise habits on body composition and bone density in elementary and junior high school students and the relationship between parent-child exercise habits; Survey in three towns in Aomori Prefecture Niioka, Yamato 新岡, 大和 Kogawa, Terumi 古川, 照美 Tanaka, Naoki 田中, 尚樹 Harima, Yuko 播摩, 優子 Shimizu, Ryo 清水, 亮 Tanikawa, Ryoko 谷川, 涼子 parent and child exercise habits body mass index body fat percentages bone density 親子 運動習慣 BMI 体脂肪率 骨密度 [Objective] This study aimed to evaluate the height, weight, body fat percentage, and bone density of elementary and junior high school students to identify the differences that arise in their responses to exercise habits. Additionally, the relationship between the exercise habits of parents and their children was examined. [Methods] The research participants were students, ranging from the fifth grade of elementary school to the third grade of junior high, along with their parents, across three municipalities in the Aomori Prefecture. In 2022 and 2023, parents and their children eligible for health checkups were requested to complete a survey on their lifestyle and dietary patterns. A total of 155 pairs of children and their parents were included, while others were excluded owing to the lack of obtainable responses. The children underwent body composition and bone density assessments. Information on factors such as age, sex, height, exercise habits, and exercise duration was collected from both children and parents through a self-administered questionnaire. [Results] The survey results indicated that the children's height and weight exceeded the national and Aomori Prefecture averages, with normal body fat percentages. There were no significant differences in height, weight, body fat percentage or bone density, according to exercise habits, for both boys and girls. Furthermore, no relationship was found between the exercise habits of parents and their children. [Conclusion] There were no significant differences in height, weight, body fat percentage, and bone density both elementary and junior high school students based on their exercise habits. Similarly, no relationship was observed between the exercise habits of parents and their children. This may be attributed to the adolescent age group, as they tend to exercise with peers in club activities rather than with their parents, which was common before adolescence. 〔目的〕　本研究の目的は，小・中学生の運動習慣の有無による身長，体重，体脂肪率，骨密度の違いを明らかにすること，さらに親子の運動習慣との関係性を明らかにすることである。 〔方法〕　研究対象は青森県の3つの自治体における小学校5年生から中学3年生までの生徒，およびその保護者であった。2022年および2023年に，健診の対象となる子どもたちとその保護者に対し，生活習慣と食生活に関する調査の依頼を行った。親子双方の回答が得られなかったものを除外し，解析対象者は子どもと保護者それぞれ155組であった。子どもは体組成測定，骨密度測定，質問紙調査を行った。親子とも自記式調査票にて年齢，性別，身長，運動習慣の有無とその時間を聴取した。 〔結果〕　子どもの身長，体重は全国平均および青森県平均より高く，体脂肪率は標準であった。男女全てにおいて運動習慣の有無による身長，体重，体脂肪率，骨密度の違いはなかった。また，親子の運動習慣に関係性はなかった。 〔結論〕　運動習慣の有無による小中学生の身長，体重，体脂肪率，骨密度に差は認められなかった。また，親子の運動習慣には関連性は認められなかった。これは対象の年齢が思春期にあたることで，思春期前のように親子で運動するのではなく，部活動などで同世代の仲間と運動をするようになった可能性がある。 journal article 青森県立保健大学 2025-07-25 VoR 青森保健医療福祉研究 1 7 40 47 Aomori Journal of Health and Welfare 2435-6794 https://auhw.repo.nii.ac.jp/records/2000170 eng J-STAGE https://doi.org/10.60395/ajhw.7.1.40
