title: Breast cancer screening programmes: challenging the coexistence with opportunistic mammography.
abstract: OBJECTIVE
  This study investigated predictive factors of women's participation in organized mammography screening (OrgMS) and/or opportunistic mammography screening (OppMS) when the two screening modes coexist.
  
  
  METHODS
  Questionnaires were sent to 6,000 women aged 51-74 years old invited to attend an OrgMS session between 2010 and 2011 in France. Data collected concerned the women's healthcare behaviour and their socioeconomic characteristics. Women without a personal or family history of breast cancer that could explain their participation in OppMS were retained in the generalized logits analysis.
  
  
  RESULTS
  The data of 1,202 women were analysed. Of these, 555 (46.2%) had attended OrgMS only, 105 (8.7%) OppMS only and 542 (45.1%) had performed both OrgMS and OppMS. Multivariable analyses showed that women who had regular gynaecological check-ups were more likely to perform OppMS only or both OrgMS and OppMS, OR 95% CI were 2.1 [1.1-3.9], 1.9 [1.4-2.6], respectively. Being employed also increased participation in OppMS only [OR: 2.1 (1.2-3.7)] or both OrgMS and OppMS [OR: 1.5 (1.1-2.05)].
  
  
  CONCLUSIONS
  In countries where OrgMS and OppMS coexist, strategies involving gynaecologists, referring doctors or company doctors and the organization of healthcare services to promote adequate screening round may help to reduce the overuse of mammography.
