The liabilities of iron deficiency

Area of Science:

• Hematology
• Nutritional Science
• Public Health

Background:

• Iron's historical recognition as a potent hematinic.
• Ongoing scientific debate regarding the precise functional roles of iron.
• Significant socioeconomic consequences of iron deficiency due to its high global prevalence.

Purpose of the Study:

• To review the literature on iron deficiency anemia.
• To highlight the global prevalence and impact of iron deficiency anemia.

Main Methods:

• Literature review of anemia and iron deficiency prevalence.
• Analysis of global population data.

Main Results:

• Approximately 30% of the global population (nearly 4.5 billion) suffers from anemia.
• An estimated 500 to 600 million people have iron deficiency anemia.

Conclusions:

• Iron deficiency anemia is a major global health concern.
• Further research is needed to fully understand iron's functional roles and to combat deficiency.
