Abstract
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.
Highlights
Colorectal cancer (CRC) is the third most common cancer worldwide (International Agency for Research on Cancer [IARC], 2015)
A total of 2,004 general public (GP) and 323 ethnic minority (EM) participants were included in the study
This is the first study to examine the difference in the uptake rate of CRC testing between GP and ethnic minorities (EM) people in a mainstream Chinese society
Summary
Colorectal cancer (CRC) is the third most common cancer worldwide (International Agency for Research on Cancer [IARC], 2015). This study aimed to compare the uptake of CRC testing in the general public and in ethnic minorities in Hong Kong. Results: 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. Conclusions: 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. Health professionals can play a highly influential role in promoting such testing, among ethnic minorities
