Outline of Final Research Achievements	The purpose of this application project was to examine the effect of an opportunity-based intervention for breast cancer screening (dispatching mammography screening vehicles to workplaces) to improve the screening rate through an establishment-based cluster-randomized controlled trial. As a result, in the working population, where the breast cancer screening rate was lower than that of the general population, an opportunity-providing intervention that dispatched mammography screening cars to the workplace significantly improved the breast cancer screening rate. This result exceeded the current government target of 50%. In addition, the effects of dispatching medical examination vehicles were most significant among those who had never undergone medical examinations, suggesting that the impact of opportunity-providing interventions was exceptionally high among those who were less likely to develop healthy behaviours.

Academic Significance and Societal Importance of the Research Achievements	職場へのマンモグラフィ検診車派遣は、従来実施されてきた個人への情報提供介入による検診受診勧奨と比較して、乳がん検診受診率を大きく向上させた。この効果は、1年間で当面の政府目標である50％を超えており、これまでに受診歴のない層により有効であることが示された。本成果は、壮年期女性の重要な健康課題である乳がんの早期発見への解決策のひとつとなると考えられた。
