Since the beginning of its activities, iron-deficiency anemia rates among students in the schools of Santa Luzia do Itanhy/SE have been reduced from 32% to 5.8%. Starting in 2015, the initiative gained scalability and began to be reapplied in other locations, such as Boquim/SE and Borba/AM. In these locations, anemia rates were reduced from 25% to 4.8% and from 59% to 3.9%, respectively. As a result of these achievements, the Hb project won the Banco do Brasil Foundation Social Technology Award in 2013, and in 2017, the experience in the village of Axinim, in the municipality of Borba/AM, won the “Mostra Brasil, Aqui Tem SUS” public call in the Conasems Webdocs Award category. In 2023, the focus was on validating a mathematical model and a mobile app under development with the Federal University of Juiz de Fora. Five schools from different districts were selected to collect 383 blood samples, resulting in the diagnosis of 55 children with iron-deficiency anemia, 33 of whom began treatment. Additionally, the educational magazine *"Battle in the Arteries: The Worms Attack"* was printed, and the "HB Workshop" was created in partnership with NHAM and the nursing team from the Health Department, aiming to raise community awareness in a playful and engaging way. In 2024, ferritin level tracking was implemented in the TAG management system, allowing for the automatic generation of measures in alert cases. Participatory strategies were developed to raise awareness and promote changes in dietary and hygiene habits among children aged 2 to 8, following the best practices from the Ministry of Health. An action protocol was also created for the pilot plan communities, aiming to treat iron-deficiency anemia in diagnosed children, with significant results in controlling anemia prevalence among students in the participating schools.
