Abstract
BackgroundConsistent participation in colorectal cancer (CRC) screening with repeated fecal immunochemical test (FIT) is important for the success of the screening program. We investigated whether lifestyle risk factors for CRC were related to inconsistent participation in up to four rounds of FIT-screening.MethodWe included data from 3,051 individuals who participated in up to four FIT-screening rounds and returned a lifestyle questionnaire. Using logistic regression analyses, we estimated associations between smoking habits, body mass index (BMI), physical activity, alcohol consumption, diet and a healthy lifestyle score (from least favorable 0 to most favorable 5), and inconsistent participation (i.e. not participating in all rounds of eligible FIT screening invitations).ResultsAltogether 721 (24%) individuals were categorized as inconsistent participants Current smoking and BMI ≥30 kg/m2 were associated with inconsistent participation; odds ratios (ORs) and 95% confidence intervals (CIs) were 1.54 (1.21-2.95) and 1.54 (1.20-1.97), respectively. A significant trend towards inconsistent participation by a lower healthy lifestyle score was observed (p < 0.05).ConclusionsLifestyle behaviors were associated with inconsistent participation in FIT-screening. Initiatives aimed at increasing participation rates among those with the unhealthiest lifestyle have a potential to improve the efficiency of screening.
Highlights
Screening and adherence to a healthy lifestyle have both shown to decrease the incidence and mortality of colorectal cancer (CRC) [1, 2]

Lifestyle behaviors were associated with inconsistent participation in fecal immunochemical test (FIT)-screening
Summary
Screening and adherence to a healthy lifestyle have both shown to decrease the incidence and mortality of colorectal cancer (CRC) [1, 2]. We have previously shown that lifestyle risk factors for CRC were associated with non-participation in the second round of FIT screening after testing negative at the first round [15]. There is limited knowledge whether these lifestyle factors are associated with inconsistent participation in multiple CRC screening rounds. Consistent participation in colorectal cancer (CRC) screening with repeated fecal immunochemical test (FIT) is important for the success of the screening program. We investigated whether lifestyle risk factors for CRC were related to inconsistent participation in up to four rounds of FIT-screening
