2.2. Bioethics
The “Nutritional Adventures” program was approved by the Ethical Committee of Prolepsis Institute (13913-n.3, on October 2021) and is being conducted in accordance with the Declaration of Helsinki. The program was implemented in schools after the official approval of the school administrative body as well as the signed consent forms of students’ parents. Parents answered the questionnaires in pre- and post-intervention phases. All questionnaires were anonymous with no potential for deidentification. Accurate matching of pre- and post-intervention responses was accomplished by a set of sociodemographic characteristics.
