  1. Prevalence of iron deficiency in the United States.

    Article - En anglais

    Objective

    - To determine the prevalence of iron deficiency and iron deficiency anemia in the US population.

    Design

    - Nationally representative cross-sectional health examination survey that included venous blood measurements of iron status.

    Main Outcome Measures

    - lron deficiency, defined as having an abnormal value for at least 2 of 3 laboratory tests of iron status (erythrocyte protoporphyrin, transferrin saturation, or serum ferritin) ; and iron deficiency anemia, defined as iron deficiency plus low hemoglobin.

    Participants

    - A total of 24 894 persons aged 1 year and older examined in the third National Health and Nutrition Examination Survey (1988-1994).

    Results

    - Nine percent of toddlers aged 1 to 2 years and 9% to 11% of adolescent girls and women of childbearing age were iron deficient ; of these, iron deficiency anemia was found in 3% and 2% to 5%, respectively.

    These prevalences correspond to approximately 700 000 toddlers and 7.8 million women with iron deficiency ; of these, approximately 240 000 toddlers and 3.3 million women have iron deficiency anemia.

    Iron deficiency occurred in no more than 7% of older children or those older than 50 years, and in no more than 1% of teenage boys and young men.

    Among women of childbearing age, iron deficiency was more likely in those who are minority, low income, and multiparous.
