Iron deficiency anemia (IDA) represents the most common cause of anemia worldwide. Because of potential irreversible neurodevelopmental impairment, its prevention during infancy is essential. We aimed to investigate the frequency of iron insufficiency among infants in a population which routine iron supplementation is implemented; and to examine related risks. A total of 501 infants, aged 9-15 months, were screened with complete blood count and serum ferritin. Infants were divided into two groups. [Group 1 (iron insufficient), [Group 1a: Iron deficiency (ID), Group 1b: IDA (IDA)], Group 2 (Iron sufficient (IS)]. Anemia was recognized in 122 (24.3%) infants. Microcytosis was observed in 110 (90.2%) of anemic infants. Group 2 accounted for 49.5% (n=248) whereas 152 (30.3%) and 101 (20.2%) infants belonged to Groups 1a and 1b, respectively. Multiple logistic regression analysis showed that male gender (OR=1.53; 95%CI 1.07 and 2.17), receiving >500 ml/day cow`s milk (OR=2.77; 95%CI 0.87 and 8.83) and incompliance to iron supplementation (OR=2.51; 95%CI 1.75 and 3.60) were distinctive characteristics of Group 1 while prevalence of iron insufficiency was higher in infants consuming less formula (OR=3.10; 95%CI 2.00 and 4.80). The most frequent reasons for incompliance were consideration of supplementation as unnecessary (n=69, 31.1%) and neglection (n= 59, 26.6%). Our study demonstrated a high frequency of iron insufficiency among infants in a setting utilizing national iron supplementation and `incompliance` to iron as the most evident risk factor for iron insufficiency. Effective counseling of families by health care providers concerning importance of compliance to iron prophylaxis is essential for prevention of iron insufficiency. We also suggest screening of infants for ID as well as IDA in settings with high frequency of iron insufficiency.
