17 Dec 2018 --- A multi-sectoral approach that goes through the schooling system is key to reducing iron deficiency in girls, according to a project trialed in Indonesia and published in the British Medical Journal (BMJ). Seeking to implement a successful program that would be scalable in other geographic regions, the team began a project in West Java, Indonesia, which followed the World Health Organization (WHO) recommendation of weekly iron-folic acid supplementation (WIFAS) to reduce anemia in adolescents aged 10-19 years and women of reproductive age.
