Organisation collective du dépistage des cancers et réduction des inégalités sociales de santé

Abstract : In accordance with the WHO's observation, there are differences in health between different population groups in France, as elsewhere, which result from the social conditions in which people are born, grow, live, work and age.In France, the reduction of social inequalities in health is a political priority, notably through successive cancer plans, with cancers being the main pathologies that provide inequalities. These plans have led to the introduction of organized screening for colorectal cancer and breast cancer, for which social and territorial inequalities of participation as well as non-adherence factors are well documented and constitute potential targets for interventions. This thesis aims to provide new knowledge and evidence to guide the policies and organization of cancer screening based on evidence, particularly for the reduction of social inequalities and territorial. She presents two studies. PRADO is an interventional study with a collective randomization unit (Grouped Islets for Statistical Information (IRIS)) multicentric, stratified on the urban / rural character and precariousness of IRIS and conducted in two parallel groups (Intervention vs Control), from 2011 to 2013 in Picardy. In the intervention arm, in addition to the usual modalities of organized screening for colorectal cancer, a screening assistant contacted by telephone those who did not carry out the screening test in the two previous round. The study showed that this intervention has increased participation and identified the conditions under which this type of intervention could reduce social inequalities. The second study evaluates the interest of a mobile radiography (the mammobile) in organized breast cancer screening. A retrospective analysis of the Orne device on five screening rounds shows that this device makes it possible to reduce the social and territorial inequalities of participation in screening. The principle of proportional universalism, the multilevel and intersectorial nature of intervention, the application of the principle of literacy and respect for informed choice appear as the foundations of a public health policy aimed at reducing social inequalities in the cancer field. The optimal mode of evaluation of these so-called complex interventions remains a major research issue.
