Burden of anemia and its underlying causes in 204 countries and territories, 1990–2019: results from the Global Burden of Disease Study 2019
Overview
Paper Summary
Anemia affects around 1.8 billion people globally and caused 50.3 million years lived with disability (YLDs) in 2019. While age-standardized rates of anemia have decreased since 1990, the absolute numbers have increased, likely due to population growth and aging. Dietary iron deficiency remains the primary cause of anemia worldwide.
