- InterventionsDuring insertion of a peripheral intraveneus catheter, 2 cc of whole blood will be collected for analysis of the iron status. Demographic, dietary and medical information will be collected.
- Primary outcome1. Iron status;
2. Serum haemoglobin;
3. Mean cell volume and serum ferritin;
4. Reticulocyte hemoglobin content.
- Secondary outcomeTo define whether following factors contribute to iron deficiency during childhood:
1. Iron status at birth (maternal iron status/anaemia, smoking during pregnancy, preeclampsia, lower gestational age and lower birth weight);
2. Postnatal needs for iron (more rapid growth);
3. Bioavailable iron (more cow milk);
4. Sex;
5. Ethnicity (European versus non-European);
6. Socioeconomic status;
7. BMI;
8. Attending day-care.
- TimepointsDuring insertion of a peripheral intraveneus catheter, 2 cc of whole blood will be collected for analysis of the iron status.

- Brief summaryRationale:
No data are available about the iron status of children in the Netherlands. Recently a large food consumption survey showed low iron intake among these children. Our hypothesis is that the iron status in young healthy children from the Netherlands might be insufficient.

Objective:
To assess the iron status in young healthy children living in the Netherlands.

Study design:
National, multi centre, descriptive, observational study.

Study population:
Healthy children living in the Netherlands aged 0,5-3 years old undergoing elective surgery.

Intervention:
During insertion of a peripheral intraveneus catheter, 2 cc of whole blood will be collected for analysis of the iron status. Demographic, dietary and medical information will be collected.

Main study parameters/endpoints:
Serum haemoglobin, mean cell volume and serum ferritin and reticulocyte hemoglobin content.
- Main changes (audit trail)13-Feb-2013: Additional information - NM
In the same blood sample obtained for assessment of the iron status we additionally assessed hepcidin and transferrin receptor to get more insight in the iron status.
Results of the planned interim analysis conducted after inclusion of 400 children showed a 2,5 times higher prevalence of iron deficiency than expected and therefore we reached sufficient power to answer the studies aim. Consequently, inclusion of more children into the study was not necessary.
