Despite evidence of breast cancer screening efficacy, the screening rate has remained less than 50% in Japan. This study aimed to evaluate the effect of an environmental approach offering on-site mammography in workplaces.
Supermarket stores were randomly assigned into two groups, the intervention group (leaflet and mammography) and the control group (leaflet). From May to July 2018, participants in the intervention group were given a leaflet informing them of the subsidies for breast cancer screening and offered the opportunity to have mammography in their workplaces. Participants in the control group were given the same leaflet, but had to arrange their own screening outside the workplace. The primary outcome was the breast cancer screening rate in 2018. The odds ratio (OR) and 95% confidence interval (CI) for having screening in the intervention group compared with the control group were estimated using multilevel logistic regression.
We analyzed data from 1624 participants (mean age 53 years) from 25 supermarket stores (intervention: 8 stores, control: 17 stores). Among participants who had not attended screening in the previous year, the screening rate was 7% in the control group and 53% in the intervention group, with an adjusted OR (95% CI) of 14.22 (8.97-22.54). The effect was greater in those who had never attended screening before.
In a worksite-based cluster randomized controlled trial in Japanese supermarket stores, an environmental approach offering mammography in workplaces substantially increased the breast cancer screening rate within 1 year (UMIN000030465).
尽管有乳腺癌筛查效果的证据，但日本的筛查率仍低于 50%。本研究旨在评估在工作场所提供现场乳房 X 光检查的环境方法的效果。
超市商店被随机分为两组，干预组（传单和乳房 X 光检查）和对照组（传单）。2018 年 5 月至 7 月，干预组的参与者收到了一份告知他们乳腺癌筛查补贴的传单，并提供了在工作场所进行乳房 X 光检查的机会。对照组的参与者收到了相同的传单，但必须在工作场所外自行安排筛查。主要结果是 2018 年的乳腺癌筛查率。使用多水平逻辑回归估计干预组与对照组相比进行筛查的优势比（OR）和 95%置信区间（CI）。
我们分析了来自 25 家超市（干预：8 家，对照：17 家）的 1624 名参与者（平均年龄 53 岁）的数据。在去年未参加筛查的参与者中，对照组的筛查率为 7%，干预组为 53%，调整后的 OR（95%CI）为 14.22（8.97-22.54）。以前从未参加过筛查的人的效果更大。
在日本超市的基于工作场所的集群随机对照试验中，在工作场所提供乳房 X 光检查的环境方法在 1 年内显著提高了乳腺癌筛查率（UMIN000030465）。
