Status of knowledge-belief-pratice and colonoscopy willingness among screened colorectal cancer residents in a community of Shanghai

ObjectiveTo investigate the status of screening knowledge, beliefs and practice among colorectal cancer residents screened in a community, and to explore the related factors affecting their willingness to participate in subsequent colonoscopy.

MethodsA total of 149 colorectal cancer residents were selected by a screening test; it was the first time for them to participate in colorectal cancer screening in 2016. A self-designed interview questionnaire was adopted, and the screening positive population investigated by means of centralized field surveys and household surveys. The questionnaire included their basic situation, knowledge and practice of colorectal cancer screening and willingness to participate in colonoscopy.

ResultsThe scores of colorectal cancer and screening knowledge among positive residents, the number of residents for good, average and poor scores were 34 (22.8%), 38 (25.5%) and 77 (51.7%), respectively. In the belief score, the number of residents for good, average and poor scores were 12 (8.1%), 63 (42.3%) and 74 (49.6%), respectively. In the subsequent colonoscopy willingness, the number of colonoscopy for those being positive in screening risk assessment table andpositive in fecal occult blood were 82 (55.03%), 87 (58.38%), 92 (61.74%), respectively. Spearman correlation analysis showed that knowledge and beliefs (r_S= 0.257, P < 0.05), knowledge and colonoscopy willingness (r_S= 0.345, P < 0.05), faith and colonoscopy willingness (r_S= 0.331, P < 0.05) were correlated. There were not statistical difference among different gender, type of medical insurance, monthly income, medical check frequency, degree of being concerned and residents' willingness to perform colonoscopy at designated hospitals and time from home to the nearest second-class hospital (P>0.05), There were statistical differences found between different scores of knowledge, different scores of belief (P < 0.05). The analysis of the two categories of non-conditional logistic regression showed that only knowledge score and belief score had statistically significant influence on the participation intention of the colonoscopy for screening positive residents of colorectal cancer (P < 0.05).

ConclusionThe knowledge, belief and practice of colorectal cancer screening should be improved in residents of the community, screening knowledge, and screening beliefs are the factors that influence the willingness of screening positive residents for further colonoscopy.
