Outline of Final Research Achievements

1) A cluster randomized controlled trial examined the long-term effects of a multi-strategic community wide intervention (CWI) utilizing social marketing (12 districts in Unnan City were followed for 13 years). The results showed a significant difference of +4.6% between groups in the percentage of physically active participants after 5 years. While, there were no significant differences in mortality after 5 years and in the incidence of certification of long-term care need after 13 years. 2) The CWI was disseminated to the entire Unnan City and Fujisawa City. In a single-group pre- and post-comparison, the physical activity of citizens was tracked. In Unnan, a significant increase (+6.2%) in the percentage of physically active people was observed after 2 years, and the effect was maintained after 5 years. Fujisawa also showed a significant increase in the duration of moderate to vigorous physical activity after 5 years. The effect of CWI was also confirmed in social implementation.

Academic Significance and Societal Importance of the Research Achievements

ポピュレーションレベルで身体活動実施者の割合を増加させることを狙った地域介入のエビデンスは極めて少ない。研究①では質の高い研究デザイン(クラスターランダム化試験)でソーシャルマーケッティングの手法を用いた多面的地域介入が身体活動実施者を増やすことを示した。本成果を発表した論文はコクラン・レビューに収載された33の地域介入研究の中で最もバイアスリスクの低い研究と評価されており、価値が高い。また、研究②③では、その手法を他地域に展開し、社会実装においても地域介入が効果的であることを示した。健康日本21の推進などにおいて、身体活動の推進を図るためのエビデンスとしての価値が高い。
