结直肠癌（colorectal cancer，CRC）是世界上最常见的癌症之一，其筛查方法如粪便潜血试验（fecal occult blood test，FOBT）是预防CRC的有效方法。然而，研究发现南亚少数民族倾向于不利用CRC筛查，应在少数民族，特别是老年人中教育CRC预防的重要性。本研究的目的是发展和实施以家庭为基础的多媒体干预，以增加香港南亚裔老年人对CRC预防的知识，并提高他们接受FOBT的动力。干预的可接受性和有效性将使用达到，有效性，采用，实施，维护（RE-AIM）framework.MethodsA集群随机对照试验进行评估。三百二十对南亚裔配对，包括一名年龄介乎五十至七十五岁的长者及一名年龄介乎十八至四十九岁的年轻家庭成员，将透过在本港十区为南亚裔人士提供支援服务的社区组织招募。将二人组随机分配至干预组或等待列表对照组。干预组将接受干预，其内容基于健康信念模型，通过多种形式的媒体，包括PowerPoint演示文稿，视频剪辑和健康信息手册。对照组将在收集干预后数据后接受干预。对于两组中的二人组，将为那些愿意接受FOBT的人安排与家庭医生的预约。将在基线和干预后评估结局。数据将使用广义线性模型程序进行分析，在意向治疗marty.DiscussionFindings这项研究将提供证据的好处，利用多媒体和家庭为基础的方法在干预发展，以提高健康促进干预少数民族的有效性。此外，研究结果将为当地社区现有的南亚少数民族支持服务中纳入干预措施提供参考。试验登记本试验于2018年7月19日在ISRCTN登记处登记（ISRCTN 72829325）。
BackgroundColorectal cancer (CRC) screening, such as fecal occult blood test (FOBT), is an effective way to prevent CRC, one of the most common cancers worldwide. However, studies found that South Asian ethnic minorities tend not to utilize CRC screening, whose importance on CRC prevention shall be educated among those from ethnic minorities, especially older adults. The purpose of this study is to develop and implement a family-based, multimedia intervention to augment the knowledge of CRC prevention among older South Asian adults in Hong Kong and enhance their motivation for undergoing FOBT. The acceptability and effectiveness of the intervention will be assessed using the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework.MethodsA cluster randomized controlled trial will be carried out. Three hundred and twenty South Asian dyads, comprising an older adult aged between 50 and 75 and a younger family member aged between 18 and 49, will be recruited in ten districts in Hong Kong through community organizations that provide support services for South Asians in local communities. Dyads will be randomly allocated to either the intervention or wait-list control group. Intervention dyads will receive intervention, whose contents are based on the health belief model, via multiple forms of media including PowerPoint presentation, video clip and health information booklet. Control dyads will receive intervention after post-intervention data are collected. For dyads in both groups, an appointment with a family doctor will be arranged for those willing to undergo FOBT. Outcomes will be assessed at baseline and post-intervention. Data will be analysed using the Generalised Linear Models Procedure in an intention-to-treat manner.DiscussionFindings of this study will provide evidence of the benefits of utilizing multimedia and family-based approaches in intervention development to enhance the effectiveness of health promotion interventions for ethnic minorities. Further, the findings would provide reference to the potential incorporation of the intervention in the existing support services for South Asian ethnic minorities in local communities.Trial registrationThis trial is registered at the ISRCTN Registry (ISRCTN72829325) on 19th July 2018.
