Based on data from the 2011, 2014 and 2016 EDIFICE surveys, we sought to identify potential links between impoverished living conditions and participation in screening in the context of organized programs (colorectal [CRC], breast [BC] and cervical cancers [CC]).
The EDIFICE observational phone surveys were conducted among representative population samples (age 40-75 yrs in 2011 [N = 1603] and 2014 [N = 1602]; age 50-75 years in 2016 [N = 1501]) using the quota method. Attitudes regarding screening were assessed in subgroups of individuals within the target age-groups for each screening program. Participation in screening and follow-up rates were assessed by asking if respondents had undergone at least one screening examination in their lifetime and within the recommended time frame (2 yrs for CRC and BC, 3 yrs for CC). Data were analyzed according to the validated EPICES vulnerability score.
For CRC, over the period 2011/2014/2016, participation increased in non-vulnerable subgroups (60% vs. 63%, NS and 63% vs. 68%, P = 0.05) as did follow-up rates (34% vs 33%, NS and 33% vs 40%, P = 0.01). Participation (60%/54%/53%) and follow-up (31%/30%/31%) were stable among vulnerable individuals. Participation was lower in vulnerable vs. non-vulnerable individuals in 2014 (P = 0.02) and 2016 (P
The 2016 EDIFICE survey confirms the increasing impact of social vulnerability on recommended screening programs, particularly for CRC.
