Abstract
Postnatal iron deficiency, especially from ages 6 to 24 months, has long-term consequences lasting into adolescence and adulthood. We aimed to characterize iron deficiency anemia among infants from one central Israeli district by demographic and laboratory parameters. A retrospective chart review was performed on all infants from a single district who had undergone a complete blood count as part of a routine survey for iron deficiency anemia during 2010-2021. Data retrieved included hemoglobin levels, mean corpuscular volume, and demographic features: sex, sector (non-ultraorthodox Jew, ultraorthodox Jew, and Arab), socioeconomic status, and type of residence. The study group comprised 101,650 infants, aged 9 to 18 months. Iron deficiency anemia, defined as a hemoglobin level <11 g/dL and mean corpuscular volume <70 fl was observed in 4296 (4.2%) of the study infants. Iron deficiency anemia was more prevalent among Arab and ultraorthodox Jewish infants, than non-ultraorthodox Jewish infants (6.6% vs. 6% vs. 3%, respectively). It was also more prevalent among infants of low socioeconomic status, and relatively common among infants of rural residence. We identified two specific sub-populations at risk of developing iron deficiency anemia: Arab and ultraorthodox Jewish infants. We recommend enhancing the nationwide intervention program for both clinicians and parents, thereby treating iron deficiency anemia promptly to avoid short- and long-term deleterious health consequences.
