Introduction: Iron deficiency anemia (IDA) is one of the most common nutritional disorders and is particularly prevalent among women and children. In addition to its impact on physical performance, IDA can adversely affect executive neurocognitive functioning. This study aimed to compare neurocognitive executive functions among individuals with iron deficiency anemia and healthy controls.
Methods: This descriptive-analytical, causal-comparative study included individuals with and without IDA who attended Aramesh Laboratory of Pathobiology and Genetics in Tehran between July and October 2024. A total of 340 participants were selected through convenience sampling, comprising 170 individuals with IDA defined as hemoglobin levels of 8–10 g/dL and ferritin levels <30 ng/mL, and 170 healthy controls with normal hemoglobin and ferritin levels. The exclusion criteria were prior iron supplementation, underlying hematologic or metabolic disorders, and lack of informed consent. Data were collected using the Behavior Rating Inventory of Executive Function–Adult Version (BRIEF-A) and analyzed using SPSS (version 27) through the non-parametric Mann–Whitney test.
Results: Findings indicated that IDA significantly impaired executive neurocognitive functions. Participants with IDA showed lower performance in attention, working memory, and cognitive flexibility, which may disrupt decision-making, emotional regulation, and task management.
Conclusions: Iron deficiency anemia is associated with executive dysfunction, and affected individuals demonstrate poorer neurocognitive executive functioning compared with healthy controls.
