Insights
Anemia is uncommon in Israeli children aged 3-6 years, with only 3.9% showing low hemoglobin. However, a significant portion had low mean red cell volume, indicating a risk for iron deficiency anemia.
Area of Science:
- Pediatric Hematology
- Public Health
Context:
- Anemia is common in infants but understudied in preschool children in Israel.
- Limited data exists on anemia prevalence in Israeli children aged 3-6 years.
Purpose:
- To determine the prevalence of anemia in Israeli children aged 3-6 years.
- To identify risk factors and predictive markers for anemia in this age group.
Summary:
- A study of 436 children in Jerusalem found only 3.9% had anemia (hemoglobin <11.0 g%).
- 17% had low mean red cell volume (MCV <74 fl), suggesting potential thalassemia or iron deficiency predisposition.
- Early blood test results and infant iron supplementation did not predict later anemia or reduce its incidence.
Impact:
- Highlights a low prevalence of anemia in this age group but identifies a subgroup at risk for iron deficiency.
- Suggests the need for targeted follow-up for children with low MCV.
- Indicates that early screening and supplementation may not be sufficient to prevent later iron deficiency.
Abstract:
Anemia in Israel is prevalent in nursing infants but there are few data on its prevalence in children aged 3-6 years. In 436 children in this age group in 18 family practice clinics in the Jerusalem area a hemoglobin level of less than 11.0 g% was found in only 17 (3.9%). Age, sex, and suburban versus urban residence were not related to the incidence of anemia. In 74 children (17%) the average mean red cell volume (MCV) was less than 74 fl but it was not associated with low hemoglobin. This finding might indicate the presence of thalassemia or a predisposition to the development of iron deficiency. This group of children is at risk of developing iron deficiency anemia and therefore requires follow-up. Results of blood tests at ages 9-12 months were available in 198 of the children but the results were not of high predictive value for the development of iron deficiency at 3-6 years of age. Iron supplementation administered to them when nursing did not affect the incidence of anemia in the children studied.

The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

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.
