Which population is most frequently affected by iron deficiency anemia?

Young children and the elderly are the populations most frequently affected by iron deficiency anemia due to several factors. Young children are particularly at risk because they have higher iron requirements for growth and development. Additionally, they may not receive adequate iron from their diet or may lose iron through gastrointestinal infections, which are common at that stage in life.

The elderly also face a higher risk due to changes in diet, absorption issues, and potential chronic conditions that can lead to iron deficiency. Their nutritional needs may not be met due to decreased appetite, medication effects, or complications from chronic diseases that hinder iron absorption or increase iron loss.

In contrast, the other groups mentioned, such as men over 50, women post-menopause, and healthy adults generally have different risk profiles for iron deficiency anemia. Men typically have lower iron needs and often have iron-rich diets. Women post-menopause no longer face the iron losses that occur with menstruation, reducing their risk. Healthy adults may be less likely to experience iron deficiency anemia unless dietary intake is severely insufficient or other health complications arise.
