Educational nutritional intervention, based on the Social Cognitive Theory
Regular school education, without educational nutritional intervention
The objective of the educational nutritional intervention is to promote in adolescents an increase in their consumption of vegetables and fruits and a decrease in their consumption of ultra-processed foods, through the application of the TSC constructs, with the use of education by pairs as the main strategy (peer leaders). It lasts two months, includes three exclusive sessions for peer leaders and five sessions for all participants, where the leaders, together with the researchers, will lead the activities of the sessions, as well as a general event for all high school students. Intervention activities include: electronic presentations, videos, food preparation and label reading workshops, individual and team reflection activities, goal setting and monitoring, board games, contests, among others. In addition, each participant is given a workbook, which contains key messages and activities for each educational session.
