Abstract

Introduction

The EDIFICE survey program began in 2005 and set out to provide a clearer insight into the participation of the French population in cancer screening programs. Since then, the surveys have been repeated every 3 years for breast, colorectal and prostate cancer. In 2013, we took the opportunity of a specific survey on breast cancer screening to also assess the most recent evolution in colorectal (CRC) screening participation.

Methods

EDIFICE surveys are conducted by phone interviews among a representative sample of 1600 subjects aged between 40 and 75 years, using the quota method. Since 2011, a validated questionnaire known as “EPICES” has been incorporated into the surveys to specifically study behaviors of the underserved/vulnerable subgroup. The targeted survey enrolled a representative sample of 451 women and was carried out in January 2013.

Results

The rate of women attending at least one screening test for CRC was 26%, 37%, 60%, 61% in 2005/2008/2011/2013, respectively. We observed a stabilization in the CRC screening participation rate in the overall population from 2011 to 2013. However, certain discrepancies were seen to emerge when socio-demographic characteristics were taken into consideration. There was a significant increase in the screening participation rate in the 65-69 years age group (61% in 2011 vs. 80% in 2013, P < 0.05) and a trend toward stabilization or a decrease in the screening rate in younger groups. Women belonging to the higher socio-professional category (SPC+) showed a significant decrease in participation (64% in 2011 vs. 45% in 2013, P < 0.05) which was not seen in the lower category (54% vs. 52%, NS). Women belonging to the underserved group (EPICES score ≥30) reported a statistically significant drop in the CRC screening participation rate (65% in 2011 vs. 45% in 2013, P < 0.01) and a lower screening participation rate compared to the non-underserved group (45% vs. 67% in 2013, p < 0.01).

Conclusion

These results suggest a decline in the CRC screening participation rate over recent years in both the higher socio-professional category and in the underserved population. This trend will be verified in the forthcoming EDIFICE survey planned for 2014 on a larger sample population.
