Outline
To analyze the colorectal cancer(CRC) screening results and colonoscopy compliance among rural residents in Sichuan Province, providing evidence for optimizing CRC screening strategies.
From January to December 2023, through cluster sampling, residents aged 40 to 74 from rural areas of 8 districts/counties in Sichuan Province were selected to participate in CRC screening. The high-risk rate, colonoscopy compliance rate, and lesion detection rate were calculated. The χ2 test and multivariable logistic regression model were used to analyze factors influencing colonoscopy compliance.
A total of 26 134 residents participated in the initial screening, with 5 483 identified as high-risk individuals, yielding a high-risk rate of 20.98%. Among them, 3 901 individuals underwent colonoscopy, resulting in a compliance rate of 71.15%. Multivariable logistic regression analysis showed that the compliance was significantly lower in the 70-74 age group(OR=0.55, 95% CI: 0.41-0.74) compared to the 40-44 age group. Higher education levels were associated with increased compliance. Self-employed individuals (OR=2.28, 95% CI: 1.59-3.26), those with a history of intestinal polyps (OR=3.40, 95% CI: 2.55-4.53), and those who were double-positive in both the high-risk factor questionnaire (HRFQ) and the fecal occult blood test (FOBT) (OR=3.03, 95% CI: 2.52-3.65) had higher compliance rates. Colonoscopy detected 230 cases of lesions, with a detection rate of 5.90%. Males had a higher lesion detection rate than females across all age groups.
The CRC screening program in rural areas of Sichuan Province has achieved positive results, but the compliance with colonoscopy still needs improvement, particularly among males, the elderly, and those with lower education levels. Efforts should be intensified to deliver targeted health education to these key populations, with the aim of further improving the overall compliance with colonoscopy and early detection rates.
