1538 Background: In France, after a pilot population-based screening program in 23 districts (2002–2003), a national organized program was progressively implemented starting in 2005. The EDIFICE 2 survey was conducted in 2008, 3 years after EDIFICE 1, to provide a better understanding of French people's participation in colorectal screening programs and to assess the evolution between the two periods. Methods: This second nationwide observational study, EDIFICE 2, was conducted in January 2008 among a representative sample of 1,801 subjects aged between 40 and 85 years old. The analysis focused on the target population of the national screening program (50–74 years old). Results: In 2008, 38% of subjects between 50 and 74 years (N = 928) had undergone a screening test for colorectal cancer (including fecal test or colonoscopy) versus 25% in 2005 (p < 0.05); 32% of the unscreened population (N = 575) planned to undergo a test. Colorectal cancer screening increased significantly in all age groups, especially between 65 and 69 years, and for both sexes. A most significant increase can be observed in districts with pilot programme (+ 21%). Factors influencing the probability of screening were: being encouraged by the family circle, living in a couple, the existence of a case of cancer (especially colorectal cancer) in the family circle, and fear of colorectal cancer. The main reasons for not performing the screening were: not feeling concerned, no recommendation by the GP, carelessness, no symptoms, and fear of exams or results. Conclusions: The objective rate of participation (50%), can be reached by motivating the unscreened population already planning to perform a test. The results in the pilot districts show the effectiveness of an organization of the screening. This trend of increasing testing will probably be confirmed in the future if the reasons for non-attendance in an organized program are addressed. No significant financial relationships to disclose.
