: Data were obtained from an already established data material (Ungdata survey) collected by the Norwegian Social Research institute (NOVA). The Ungdata survey was administered anonymously online during school hours with a teacher present. The pupils were informed that participation was voluntary, and the data collection was based on informed consent. Norwegian Centre for Research Data (NSD) and NOVA have assessed that the data collection and parents were informed prior to the study (a passive consent scheme). This in line with the privacy protections and regulations. Permission to access and use the data were given by NOVA at Oslo Metropolitan University on the 24.11.2020. All methods were performed in accordance with relevant guidelines and regulations.
: All participants gave written consent for publication.
