Statistics for Iron Deficiency Anemia in the United States

June 23, 2023

I don’t have real-time data. My knowledge was last updated in September 2021, so I can provide you with information based on that timeframe.

Iron deficiency anemia is a common nutritional deficiency worldwide, including in the United States. However, I can provide you with some general statistics and information about iron deficiency anemia in the United States as of my last update.

According to the Centers for Disease Control and Prevention (CDC), iron deficiency anemia affects different populations in varying degrees. Here are a few statistics:

  1. Prevalence: Iron deficiency anemia is the most common nutritional deficiency in the world. In the United States, it is estimated to affect approximately 5-10% of women of childbearing age, 2% of adult men, and 3-5% of children.
  2. Gender and Age: Iron deficiency anemia is more prevalent among women, especially those in their reproductive years, due to factors such as menstrual blood loss and increased iron requirements during pregnancy. However, it can occur in people of all ages and genders.
  3. Children and Adolescents: Iron deficiency anemia is more common in children and adolescents, especially those from low-income families. According to the National Health and Nutrition Examination Survey (NHANES) data from 2013-2016, approximately 5% of children aged 1-2 years and 9% of children aged 3-5 years had iron deficiency.
  4. Risk Factors: Several factors can increase the risk of iron deficiency anemia, including inadequate dietary intake of iron-rich foods, chronic blood loss (e.g., due to heavy menstrual periods or gastrointestinal bleeding), certain medical conditions, and pregnancy.
  5. Consequences: Iron deficiency anemia can lead to various symptoms and health complications, including fatigue, weakness, pale skin, impaired cognitive function, decreased immune function, and developmental delays in children.

Please note that these statistics may have changed since my last update. For the most up-to-date and detailed information, I recommend consulting recent reports and studies published by reputable health organizations like the CDC or the World Health Organization (WHO).
