Latinas in the United States are more likely to be diagnosed with late-stage breast cancer (BC) compared to non-Latinas. Literacy-appropriate and culturally sensitive cancer communication interventions can help address existing racial/ethnic BC disparities. We formatively developed a new BC prevention brochure for Spanish-speaking Latinas (≥35 years). Eligible women ( = 240) from a large public hospital in California were randomly assigned to one of three study arms: Group 1 received the new brochure, Group 2 included a community health worker (CHW) who delivered the new brochure's content, and a control group received a standard educational brochure. Participants completed three surveys (baseline, postintervention, 3-month follow-up) with a 100% completion rate for the first two surveys and 80.4% completion after 3 months. We assessed the difference in outcomes for BC risk knowledge, perceived BC susceptibility, and BC information self-efficacy between groups. Participant mean age was 52.3 years, and 82.1% reported low English proficiency. Mean knowledge scores increased and perceived BC susceptibility improved for all groups ( ≤ .05), yet treatment effects were not significant between groups for these outcomes. BC information self-efficacy also increased from baseline to postintervention for all groups to >80%. After 3 months, only Group 2 and the control group retained their increases and treatment effects were significant only for Group 2 compared to other groups in unadjusted and adjusted models. A CHW-delivered intervention may be more effective in improving BC information self-efficacy among Latinas compared to print material alone. More research is needed to examine the efficacy of CHW-delivered interventions.
与非拉丁裔女性相比，美国的拉丁裔女性更有可能被诊断出晚期乳腺癌 (BC)。适合读写能力和具有文化敏感性的癌症沟通干预措施可以帮助解决现有的种族/族裔乳腺癌差异。我们为西班牙语裔拉丁裔女性（≥35 岁）制定了一个新的乳腺癌预防手册。加利福尼亚州一家大型公立医院的合格女性（=240 人）被随机分配到三个研究组之一：第 1 组接受新手册，第 2 组包括一名提供新手册内容的社区卫生工作者（CHW），对照组接受标准教育手册。参与者完成了三项调查（基线、干预后、3 个月随访），前两项调查的完成率为 100%，3 个月后为 80.4%。我们评估了 BC 风险知识、感知 BC 易感性和 BC 信息自我效能在组间的差异。参与者的平均年龄为 52.3 岁，82.1%的人英语水平较低。所有组的平均知识得分都增加了，感知 BC 的易感性也提高了（≤.05），但这些结果在组间没有显著的治疗效果。BC 信息自我效能也从基线到干预后在所有组中增加到>80%。3 个月后，只有第 2 组和对照组保留了他们的增加，并且仅在调整和未调整模型中，第 2 组与其他组相比，治疗效果才有统计学意义。与仅使用印刷材料相比，CHW 提供的干预措施可能更有效地提高拉丁裔女性的 BC 信息自我效能。需要更多的研究来检验 CHW 提供的干预措施的效果。
