Ethics approval and consent to participate

: At the time of the survey, the French law in force did not require the consultation of an ethics committee for this type of observational study that does not include any acts performed or products used on the participants. Until the decree n° 2016–1537 of November 16, 2016 modifying the law n° 2012–300 of March 5, 2012 relating to research on human subjects (Jardé law), this consultation was required only for biomedical research or research in routine care.In this context, the protocol of the survey, based on a data collection by phone directly from a random sample of individuals, was only approved by an internal expert committee (CCEP) of The French Public Health Agency. In addition, a simple declaration has been made to the National Commission on Informatics and Freedoms (CNIL) in accordance with the Data Protection Act, the only formality required by regulation.Individuals contacted by phone to answer the questionnaire were informed of the optional nature of their participation and about their rights of access, rectification and opposition to the data concerning them. Informed consent was obtained from all participants.
