Kin KeeperSM Breast and Cervical Cancer Prevention: An Educational Intervention: A Community-Based Randomized Controlled Trial in Black, Latina, and Arab Women
摘要
Despite highly effective prevention strategies, breast and cervical cancer are among the leading causes of cancer morbidity and mortality in medically underserved and racial/ethnic women. This study tested the effect of the Kin KeeperSM (KK) intervention, a family-focused, educational intervention, on improvement of breast and cervical cancer health literacy and screening behavior among African American, Latina, and Arab women. The study used a longitudinal RCT design with data collection at baseline and every six months for 36 months. Female community health workers (CHWs) trained to administer the KK intervention recruited 516 women who were randomized to the KK intervention or control group (standard of care). The study included three types of participants: CHWs, CHW’s clients, and client female family members (2–4). The intervention group received the KK family-focused, curriculum-driven, educational intervention, which focused on breast health and wellness and cervical cancer prevention. The primary outcome was participation in breast and cervical cancer screenings. The secondary outcome was cancer health literacy. The KK intervention improved breast and cervical health literacy compared to the control group (p-value = 0.0007; p-value < 0.0001, respectively). The KK intervention did not significantly improve the odds of receiving a mammogram, clinical breast exam, or PAP screening when compared to the control. Both groups showed higher odds of receiving a clinical breast exam, mammogram, and PAP exam at various time points when compared to baseline. Results from this longitudinal analysis indicate that race, ethnicity, and language concordant CHWs in the homes of women of color can effectively engage other family members in preventive health education interventions and address health disparities. Yet, knowledge alone is insufficient to improve screening rates. The study supports the need for more intensive educational efforts to reduce barriers to access to cancer screening.
