Declarations

:

: The study adhered to all aspects of the Helsinki Declaration. Informed consent to participate in the study was obtained from all study participants. Study participants were briefed and debriefed about the study, the use of data and their rights to withdraw from the study and retract their data. Written informed consent was obtained from the supermarket head office representatives although written consent was not required according to the Danish Data Protection Agency or other national legislation at the time. Oral informed consent was obtained from the remaining study participants who were not just informants but co-owners of the study and actively involved in project design, planning, and implementation during the entire intervention period of the project. In Denmark, approval from the Research Ethical Committee was not required according to Danish law, as the research project was based on interview data and therefore did not contain human biological material (cf. Section 14 no. (2) in Act on Research Ethics Review of Health Research Project ExternalRef removed). The study was approved by the Danish Data Protection Agency according to the Danish Act on Processing of Personal Data (2007-58-0015).
