    Background
    One goal of the current French National Cancer Plan is to reduce health inequities in cancer control. In this study, an underprivileged population was investigated to analyze exposure to lung cancer risk factors and health care access in order to highlight ways to improve lung cancer control in that population.

    Methods
    Within the nationwide observational study EDIFICE 3, conducted by phone interviews among a representative sample of 1603 subjects aged between 40 and 75 years old, we used the “EPICES” validated questionnaire to examine the association of underserved status with lung cancer risk factors, beliefs, and health care access.

    Results
    Based on the EPICES score, underserved subjects represented 33% of the sample. These subjects subjectively perceived a higher risk of cancer compared to subjects in the served population (21% vs. 14% respectively, p<0.01). Among people with cancer, underserved subjects have a higher rate of lung cancer (10% of cancers vs. 1%, p<0.05). They also have more cancer risk factors: a high BMI (26.0 vs. 24.8, p<0.01), are active smokers (38% vs. 23%, p<0.01) with a higher consumption of cigarettes (16.0 cigarettes/day vs. 10.1, p<0.01) and for a longer period (29.4 years vs. 26.3, p<0.01), and also practice less sport (42% vs. 77%, p<0.01). They have more comorbidities: on average (2.2 vs. 1.8, p<0.01), at least one (76% vs. 65%, p<0.01), hypertension (24% vs. 19%, p<0.05), cardiovascular disease (13% vs. 9%, p<0.05) and respiratory disease (13% vs. 7%, p<0.01). Access to healthcare is not an issue (consultations with a general practitioner are more frequent for the underserved group: 5.4 vs. 3.7 per year, p<0.01). They trust the national health system less (an average score from 1 to 10; 6.0 vs. 6.3, p <0.05). However, 85% of underserved subjects think that lung cancer can be efficiently screened vs. 78% of the served population (p<0.01).

    Conclusion
    In order to reduce inequities in lung cancer control, the effort of upstream interventions should be focused on prevention, as healthcare access does not discriminate. Underserved subjects have a high level of trust in lung cancer screening but a riskier behavior in terms of smoking. This constitutes new targets for specific communication campaigns and Health authorities’ interventions.
