Abstract:
Objective:To evaluate the compliance rate of screening colonoscopy and associated factors in high-risk populations of colorectal cancer (CRC) in urban China.
Methods:CRC screening data from the Program of Cancer Screening in Urban China conducted in 12 provinces in 2012-2014 was used in the present study. All 97 445 participants were asked to take epidemiological questionnaire survey to evaluate their cancer risk. Participants who were evaluated as "high risk for CRC" were recommended to receive colonoscopy at designated hospitals. Chi-square tests were used to compare the differences of participation rates between groups. Multivariate logistic regression models were applied to explore the potential factors associated withthe compliance rate of screening colonoscopy.
Results:Overall, 97 445 participants of CRC high-risk were included in this analysis, and 14 949 of them took screening colonoscopy, yielding a participation rate of 15.3%. The participation rate varied greatly across provinces, ranging from 25.2% (2 785/11 071) in Heilongjiang to 9.7% (1 698/17 515) in Liaoning. Moreover, the participation rate in 2013-2014 was significantly higher than that in 2012-2013 (17.1%(9 766/57 280) vs 12.9% (5 183/40 165), χ2=57.67, P<0.001) . The multivariate logistic regression analyses showed that: compared with individuals of 40-49 years old, individuals of 50-59 or 60-69 years old were more willing to accept screening colonoscopy, with OR of 1.17 (95% CI: 1.12-1.22) and 1.13 (95% CI: 1.08-1.19), respectively; compared with uneducated individuals, individuals with good educational background of equivalent to high school or higher (OR=1.29, 95% CI:1.10-1.50) were more willing to accept screening colonoscopy; compared with individuals who never took fecal occult blood tests (FOBT) before, individuals with previous positive FOBT results (OR=1.40, 95% CI:1.31-1.50) were more willing to accept screening colonoscopy; compared with individuals with no inflammatory bowel diseases (IBD), individuals with IBD (OR=1.63, 95%CI:1.56-1.69) were more willing to accept screening colonoscopy; Compared with individuals without polyp history, individuals having history of previous polyp detection (OR=1.43, 95% CI:1.37-1.50) were more willing to accept screening colonoscopy; compared to individuals with no family history of CRC, individuals with history of CRC (OR=1.60, 95% CI:1.53-1.66) were more willing to accept screening colonoscopy.
Conclusion:The overall participation rate of screening colonoscopy among high-risk population of CRC in the 12 participating sites was 15.3%. The study findings indicated that age, education level, history of past fecal occult blood test, IBD, history of polyp, family history of CRC were associated with the compliance rate of colonoscopy in this population-based CRC screening program.
