我们对公共教育和提供者干预进行了一项对照试验，以提高越南裔美国人的结直肠癌 (CRC) 筛查率，而越南裔美国人的筛查率通常低于非西班牙裔白人。公共教育干预措施包括越南语 CRC 筛查媒体活动、分发健康教育材料和热线电话。提供者的干预包括继续医学教育研讨会、时事通讯和 DVD。加利福尼亚州阿拉米达县和圣克拉拉县的越南人于 2004 年至 2006 年接受了干预；德克萨斯州哈里斯县的越南人受到控制，没有受到干预。采用准实验研究设计，对 533 名参与者进行干预前和干预后调查，以评估联合干预措施。干预社区中曾经接受过乙状结肠镜检查或结肠镜检查的干预后与干预前比值比是对照组社区的 1.4 倍。知识和态度调节干预措施对结直肠癌筛查行为的影响。媒体曝光介导了干预对知识的影响。通过媒体提高CRC知识有助于提高干预措施的有效性。
We conducted a controlled trial of a public education and provider intervention to increase colorectal cancer (CRC) screening rates among Vietnamese Americans, who typically have lower rates than non-Hispanic Whites. The public education intervention included a Vietnamese-language CRC screening media campaign, distribution of health educational material, and a hotline. The provider intervention consisted of continuing medical education seminars, newsletters, and DVDs. Vietnamese in Alameda and Santa Clara Counties, California, received the intervention from 2004 to 2006; Vietnamese in Harris County, Texas, were controls and received no intervention. A quasi-experimental study design with pre- and postintervention surveys of the same 533 participants was used to evaluate the combined intervention. The postintervention-to-preintervention odds ratio for having ever had a sigmoidoscopy or colonoscopy was 1.4 times greater in the intervention community than in the control community. Knowledge and attitudes mediated the effect of the intervention on CRC screening behavior. Media exposure mediated the effect of the intervention on knowledge. Improving CRC knowledge through the media contributed to the effectiveness of the intervention.
