What Is Already Known About This Topic?:
The Sustainable Development Goals target a 50% reduction in anemia among women of reproductive age by 2025 and the elimination of all forms of malnutrition by 2030. However, robust evidence documenting temporal changes in anemia prevalence remains scarce.
What Is Added By This Report?:
Drawing on large-scale national health examination data, this report demonstrates overall progress in reducing anemia among urban women in China between 2019 and 2024. However, it also reveals increasing prevalence in several provinces and a growing burden of moderate-to-severe anemia specifically among women aged 40-49 years.
What Are The Implications For Public Health Practice?:
Risk-stratified and targeted anemia prevention and control strategies are urgently needed. Priority should be given to women aged 40-49 years, women of reproductive age residing in high-burden provinces, and geographic areas where anemia prevalence either exceeds 20% or demonstrates an upward trend.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Factors Affecting Erythropoiesis
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.
