Efficacy of Community Health Worker-Delivered Family Health History-Based Breast Cancer Education and Services Among...

Family health history (FHH) is an evidence-based genomics tool used in cancer prevention and education. Chinese Americans, the largest Asian American group, face unique barriers in FHH collection and communication. This study aimed to evaluate the efficacy of culturally and linguistically appropriate community health worker (CHW)-delivered FHH-based breast cancer (BC) education and services to Chinese Americans. A total of 1129 Chinese Americans received FHH-based BC education and service delivered by our trained Chinese American CHWs. Participants responded to evaluation surveys before, immediately after, and 3 months after the education and service. Participating Chinese Americans showed significant increases in rates of collecting FHH of BC, discussing FHH of BC with family members, informing their primary care physicians of their FHH of BC, and discussing their FHH of BC with their primary care physicians at 3 months post-education and service compared to the baseline data (all Ps < 0.01). Attitudes, intention, and self-efficacy related to FHH of BC communication and collection and FHH of BC knowledge were improved both immediately after and 3 months after the delivery of the education and services (all Ps < 0.01). Within 3 months, ~ 14.3% of participants who had a high risk of BC based on FHH reported visiting geneticists for genetic evaluation. Our Chinese American CHW-delivered FHH-based BC education and services showed initial success in increasing knowledge, collection and communication of BC-related FHH, and genetic service utilization among Chinese American participants. This study can serve as a starting point for conducting more robust studies, such as randomized controlled trials, in the future.
