The programme is designed to address the triple burden of malnutrition among adolescents in Indonesia by reducing anemia prevalence while promoting healthy eating and physical activity behaviors. The Aksi Bergizi programme has successfully changed adolescents’ knowledge and behaviours in nutrition which in turn will lead to improvement in their nutritional status. An impact evaluation indicated a significant increase in the proportion of adolescent girls who consumed Weekly Iron Folic Acid Supplementation, as well as adolescents who consumed vitamin A-rich fruits and vegetables, did physical activity for 60 minutes every day and had good knowledge of nutrition. The programme applies a strong gender lens to address gender inequality in nutrition by supporting adolescent girls vulnerable to iron deficiency anemia, preventing the triple burden of nutrition for both adolescent girls and boys, and mitigating gender norms that affect the dietary intake and physical activity of adolescents. It engages with multiple stakeholders across health, education and religious affairs, whereas traditional programs tend to engage a single provincial/district government vertical. The cascade training, in which knowledge flows from the district facilitator to teachers and then on to students, embeds the program with local leadership, increasing ongoing sustainability of the program.
