Colorectal cancer (CRC) is one of the most common cancers. This study aimed to compare the uptake of CRC testing in the general public and in ethnic minorities in Hong Kong.
This cross-sectional survey covered 2,327 South Asian and Chinese adults aged over 50, recruited from two separate studies. A structured questionnaires were administered by research staff over the telephone or in face- to-face interviews.
The uptake rate of CRC testing among South Asians was significantly lower than that of the general population in Hong Kong. Factors associated with the uptake rate were health professional's recommendation, perception of regular visits to doctor, use of complementary therapy, ethnicity, perceived susceptibility to cancer, presence of chronic illness, and education level. In addition, a significant interaction (p<0.05) between ethnicity and health professionals' recommendations was found, after adjustment for the main independent factors identified.
Older people with lower educational attainment, without chronic illness and those have lower perceived susceptibility to cancer may be targeted for CRC testing promotion in the society. In addition, health professionals can play a highly influential role in promoting such testing, particularly among ethnic minorities.
结直肠癌（CRC）是最常见的癌症之一。本研究旨在比较香港普通公众和少数族裔人群对CRC检测的接受情况。
这项横断面调查涵盖了从两项独立研究中招募的2327名年龄在50岁以上的南亚和中国成年人。研究人员通过电话或面对面访谈的方式发放结构化问卷。
南亚人群中CRC检测的接受率显著低于香港普通人群。与接受率相关的因素包括医疗专业人员的建议、定期看医生的认知、使用补充疗法、种族、对癌症易感性的认知、慢性病的存在以及教育水平。此外，在对确定的主要独立因素进行调整后，发现种族与医疗专业人员的建议之间存在显著交互作用（p<0.05）。
社会上可针对教育程度较低、无慢性病且对癌症易感性认知较低的老年人推广CRC检测。此外，医疗专业人员在促进此类检测方面可发挥极具影响力的作用，尤其是在少数族裔中。
