title: Iron status in a group of Norwegian children aged 6-24 months.
abstract: An adequate iron status is of vital importance for health and development in infancy and early childhood. Iron status was evaluated in a group of full-term Norwegian children followed longitudinally, at the ages of 6 mo (n = 278), 12 mo (n = 249) and 24 mo (n = 231) by measuring haemoglobin (Hb), mean cell volume (MCV) and serum ferritin. At 6, 12 and 24 mo of age, 3, 10 and 12%, respectively, had iron deficiency anaemia (IDA) defined as Hb <110 g/l in combination with ferritin <15 microg/l. With more restrictive criteria for defining IDA (Hb <110 g/l or <105 g/l in combination with ferritin <12 microg/l), the prevalence decreased to 1-2% at 6 mo and 2-5% at 12 and 24 mo of age. If children with a history of fever in the previous month were excluded, the proportion of children with depleted iron stores (ferritin <10 microg/l) increased from 2 to 3% at 6 mo, from 5 to 7% at 12 mo and from 9 to 13% at 24 mo.
  
  
  CONCLUSIONS
  Mild iron deficiency anaemia exists among otherwise healthy Norwegian infants and toddlers. The prevention and early treatment of iron deficiency should be a priority for the child health services.
