Compliance with Ethical Standards
:
: The authors declare that they have no conflict of interest.
: All procedures performed in studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Declaration of Helsinki and its later amendments or comparable ethical standards. Oslo Metropolitan University and NOVA provided IRB approval for the study in collaboration with the University of Bergen.
: In this study, we used data from the main study Children’s level of living – the impact of family incomes; therefore, there was no direct contact with human participants. Informed consent was obtained from all individual participants included in the main study, whereas both the parents and the child were required to consent to the child’s participation in the study (Sandbæk 2009; Sandbæk and Pedersen 2010).
