Sociodemographic predictors of participation in colorectal cancer screening.

Participation in colorectal cancer screening was high in Denmark in 2014 and 2015. Large differences in participation were seen between sociodemographic subgroups, potentially resulting in social inequality in the benefits from screening. Future efforts to increase participation should focus on the low compliance subgroups, such as singles, non-Western immigrants and people from the lowest socioeconomic groups.
