Outline of Final Research Achievements

n intervention study was conducted with the participation of 275 cafeteria patrons from four Japanese companies to examine the effect of BGM broadcasts of a song regarding the appropriate amount of salt intake.

The control group was received the intervention with visual materials, while the intervention group was with BGM and visual materials for 5 weeks each after the baseline survey and before the one-year follow-up survey.
The Mann-Whitney U-test was used to determine the difference in the estimated salt intake between the groups between the baseline survey and the one-year follow-up survey.During the same period, odds ratios for improvement in salt behavior scores obtained from the salt check sheet were examined using logistic regression analysis.

Academic Significance and Societal Importance of the Research Achievements

本課題は、減塩についてのBGM放送の効果を検証した世界でもまれな研究である。BGM放送はその性質上食堂などの食環境下で利用しやすく、汎用性が高い新たな減塩のポピュレーションアプローチとなり得る。
効果の検証および、その効果が特に有効な特性を検討、提示することは我が国の減塩対策の一助となり得るものである。
