abstract = {生活習慣病は，生活習慣が発症原因に深く関与する疾患の総称であり，癌などの三大死因の発症リスクを高める危険性がある．特に食事は，人間活動に必須であり日常的に行われるが，高カロリー・栄養バランスの悪い食事は生活習慣病につながる可能性が高い．健康な食生活を目指すために，主にモバイルデバイスに食事内容を記録する手法が利用されるが，栄養素の計算・記録負荷が大きく，また利用者がつねに能動的に記録を行う必要があり，継続利用には利用者個人の動機に依存する傾向がある．本研究では，これまでの食事内容の記録手法に「グループでのゲーム要素」および「食事内容に対する他者の評価」を加えることで，グループ全体での低負荷での食事の行動変容を促進する新たな記録手法，HealthyStadiumを提案する．HealthyStadiumはグループ内において食事画像の共有および，その健康度合いで対戦するソーシャルメディアである．健康度合いの評価は，1人1票の投票形式で行われ投票数の多い方が勝利となる．本アプリケーションを用いて，大学生10人を対象に28日間にわたる評価実験を実施した．既存の記録アプリケーションと比較して，HealthyStadiumでは食事の記録回数が20%上昇し，記録負担が低減した．さらに，行動変容ステージモデルの評価指数の1つである自己効力感を増加させる効果を確認できた．



	Lifestyle-related diseases are a general term for diseases in which lifestyle is deeply involved in the pathogenesis, and there is a risk of raising the risk of developing three major causes of death such as cancer. Diet, in particular, is essential for human activities and is carried out on a daily basis, but diets with high calorie and poor nutritional balance are likely to lead to lifestyle diseases. To aim for healthy eating habits, a method of recording dietary contents in mobile devices is mainly used, but calculation of nutrients and recording load are large and it is required to always positively record, so there is a tendency to depend on the motivation of individual users for continuous use. In this research, we propose “HealthyStadium”, a new recording method to promote eating behavior change in the whole group by adding “game element in group” and “evaluation of others to meal contents” to the existing recording method. HealthyStadium is a social media which shares meal photo in the group and makes users fight with its health degree. Evaluation of the degree of health is done by voting one by one person, and users with many votes win. Using this application, we conducted an evaluation experiment for 10 university students over 28 days. Compared with the existing recording application, the number of meals recordings increased by 20% in HealthyStadium, and the burden of the recording was alleviated. Furthermore, the self-efficacy which is one of the evaluation indexes of the behavior change stage model was also improving.},
