Abstract
Objective: To investigate the associations between composition of the diet at 18 months of age and ferritin and haemoglobin levels. Design: Cross-sectional study. Subjects: A total of 796 children taking part in the Avon Longitudinal Study of Pregnancy and Childhood (ALSPAC). Main outcome measures: Food and nutrient intakes and haemoglobin and ferritin levels at 18 months. Methods: Diet was assessed by a 3-day unweighed food record. A heel-prick capillary blood sample was taken for measurement of ferritin and haemoglobin. Results: Ferritin levels were negatively associated with the amount of cows' milk consumed (r=−0.2462, PP=0.024) or any vegetables (P=0.030). The associations between nutrient intakes and ferritin and haemoglobin levels remained on adjustment for socio-demographic factors. The prevalence of low haemoglobin levels was higher in those children who consumed no meat or poultry (28.8% vs 19.0% overall, P=0.044). Conclusions: Higher levels of milk and dairy product consumption are associated with lower ferritin levels in children of this age, and over-reliance on these foods should be avoided. Fruit and vegetable consumption should be encouraged, and the inclusion of a little meat or fish in the diet of small children is advisable. Sponsorship: University of Bristol.
