Aims Eight percent of colonoscopies performed in the Danish Colorectal Cancer Screening Program are incomplete. Our aim was to investigate the association between socioeconomic status (SES) and incomplete colonoscopy (IC) in the Screening Program.

Methods We conducted a register-based study utilizing data from the Danish Colorectal Cancer Screening Database and various Danish national registers. 71,973 participants with positive Fecal Immunochemical Tests were included. Main exposure was SES status defined by income and education level. Income was divided into quartiles, and education was categorized as basic school, high school/vocational education and higher education. Outcome was defined by complete or incomplete colonoscopy, stratified by reason for IC. Analyses were done using multivariate logistic regressions adjusting for age, gender, civil status, comorbidity and use of peristalsis-affecting medicine.

The odds ratio (OR) of having an IC due to inadequate bowel preparation was 1.67 (95%CI: 1.46;1.91) in the 1st income quartile, 1.38 (95% CI: 1.21;1.56) in the 2nd quartile and 1.17 (95% CI: 1.03;1.33) in the 3rd quartile compared to the 4th quartile. An OR of 0.87 (95% CI: 0.79;0.97) was estimated for high school/vocational education compared to higher education, whereas basic school was not significantly different. OR of 1.19 (95% CI: 1.05;1.35) for 1st income quartile and 1.19 (95% CI: 1.06;1.34) for 2nd quartile was estimated for IC due to other causes, whereas no differences in OR for educational level was found.

Conclusions SES was associated with increased odds of IC, especially measured by income and to a lesser degree for educational level.
