Objectives: Iron deficiency (ID) and iron deficiency anemia (IDA), during the first years of life, are associated with delayed motor and neurological development. Many studies evaluated iron status without an assessment of an acute-phase protein to identify infection. Because most indicators of iron status are influenced by infection, these data may underestimate the ID prevalence. A food consumption survey in the Netherlands showed that the mean iron intake of children ages 2 to 3 years was below the advised adequate intake of 7 mg/day. The aim of the study was to investigate iron status in a well-defined, healthy population of young children in the southwestern region of the Netherlands and to identify risk factors for ID. Methods: We conducted a multicenter, observational study in healthy children ages 0.5 to 3 years. We defined ID as ferritin <12 mu g/L and IDA when, in addition, hemoglobin was <110 g/L. Children with elevated C-reactive protein levels (>5 mg/L) or underlying causes for anemia were excluded. Parents filled in a questionnaire to identify risk factors for ID. Results: We included 400 children in the study. ID and IDA were detected in 18.8% and 8.5% of the children, respectively. The present use of formula and the visit of preschool/day care were associated with a lower prevalence of ID, and a high intake of cow's milk was associated with a higher prevalence of ID, after adjustment for age. Conclusions: ID is present in 18.8% of healthy children ages 0.5 to 3 years and living in the southwestern region of the Netherlands. The present visit of preschool/day care and the use of formula are associated with a reduced risk of ID, whereas a high intake of cow's milk is associated with an increased risk of ID.
