[Backgrounds] Many breast cancer survivors (BCSs) still remain physically inactive. Lack of receiving physical activity (PA) information from oncology care providers (OCPs) is known as one of patient-reported barriers to get exercise habits. [Methods] To clarify OCPs’ attitudes, practices, barriers and facilitators of PA promotion in BCSs, we conducted web-based surveys for all members of Japanese Breast Cancer Society (JBCS) and Japanese Association of Cancer Rehabilitation from Dec. 2018 to Feb. 2019. [Results] Of 10,830 OCPs who asked to answer the web-based survey, 1,029 (9.5%) responded. Of those, 17% recognized contents about PA recommendation in JBCS guidelines in detail. And, 23% informed BCSs about benefits of PA routinely. Logistic regression analysis showed that the associated factors about OCPs’ routinely informing about benefits of PA were as follows: 1) recognition that explaining to BCSs about PA includes in OCPs’ own job roles (OR: 5.9, 95% confident interval (95%CI)=2.48-14.02, p&lt;0.001), 2) recognition that explanation about PA is necessary for over 60% BCSs (OR: 2.4, 95%CI=1.46-4.11, p&lt;0.001), 3) presence of exercise programs in their own institutions (OR: 1.9, 95%CI=1.07-3.46, p=0.028), 4) recognition that explaining to BCSs about PA was one of OCPs’ own roles in their institute(OR: 1.8, 95%CI=1.09-2.92, p=0.022), 5) awareness of detailed contents about PA recommendation in JBCS guidelines (OR: 1.7, 95%CI=1.13-2.70, p=0.012), 6) presence of OCPs’ confidence about informing about PA (OR: 1.6, 95%CI=1.10-2.47, p=0.016), 7) presence of outpatient consultation by nurses (OR: 1.6, 95%CI=1.09-2.29, p=0.017), 8) belief in certainty of association between PA and breast cancer death risk (OR: 1.6, 95%CI=1.05-2.34, p=0.027), 9) high levels of PA in OCPs (OR: 1.04, 95%CI=1.02-1.06, p&lt;0.001). Logistic regression analysis showed that the associated factors about OCPs’ awareness of detailed contents about PA recommendation in JBCS guidelines were as follows: 1) to have already seen the part of epidemiology and diagnosis in JBCS guidelines 2018 (OR: 4.3, 95%CI=3.46-16.95, p&lt;0.001), 2) presence of OCPs’ confidence about informing about PA (OR: 3.0, 95%CI=1.92-4.63, p&lt;0.001), 3) recognition that explaining to BCSs about PA includes in OCPs’ own job roles (OR: 2.9, 95%CI=1.34-6.36, p=0.007), 4) to have checked clinical practices by reading JBCS guidelines 2018 (OR: 2.4, 95%CI=1.10-5.27, p=0.028), 5) belief in certainty of association between PA and breast cancer death risk (OR: 2.0, 95%CI=1.24-3.09, p=0.004), 6) presence of case meeting about BCSs’ healthy lifestyle or survivorship care with multidisciplinary team as needed (OR: 1.7, 95%CI=1.16-2.61, p=0.008). [Discussions and Conclusion] This study clarify OCPs’ attitudes and practices about PA promotion in BCSs. To facilitate PA promotion, educational/training program for OCPs, development of institutional resources and research to prove benefits of PA in Japanese population are required. And, conducting case meeting with multidisciplinary team and checking clinical practices by looking at the evidences will enhance dissemination and implementation of the guideline.
