Declarations
:
: These surveys were conducted anonymously, with no identifying information such as names, personal identification numbers, or dates of birth being collected. As the aim was not to generate new knowledge about health or disease, the surveys were not classified as health research under Norwegian regulations. The Regional Committees for Medical and Health Research Ethics (REC) therefore concluded that approval was not needed (REC 896904). Examples of activities that do not require approval from REC are using anonymous information and assessing health conditions. Anonymous information means information in which names , personal identification numbers , and other unique characteristics are removed so that data can no longer be linked to an individual (Sect. 2 of the Health Registry Act) [ , ]. Consent to participate was therefore obtained by a positive response to the interviewer’s questions about participation. Approval was also requested from the Norwegian Agency for Shared Services in Education and Research (SIKT), under reference number 677162. They concluded that the study did not require an assessment from SIKT as the study would not process information that could identify individuals either directly or indirectly. The study was conducted in accordance with the Declaration of Helsinki [ ].
