Understanding the effect of anaemia requires unbiased and comparable estimates of anaemia burden. To our knowledge, we produced the first set of global estimates of anaemia burden by location, year, age, and sex using the WHO 2024 elevation adjustment method and compared them with estimates using the previous method. Policy makers should consider this modification when designing interventions to manage and prevent anaemia, particularly in regions most affected by changes in elevation adjustment.
The Lancet Haematology published a clinical update in Oncology on 01 Apr 2026.
The item focuses on Implications of changes in WHO haemoglobin elevation adjustment guidelines on global, regional, and national anaemia burden, 1990–2023: a population-based modelling study.
