Iron status of young Vietnamese children in Australia.
OBJECTIVE
The aim of this study was to estimate the prevalence of iron deficiency in Vietnamese children living in Australia and to identify risk factors associated with iron deficiency.


METHODS
A cohort of healthy term Vietnamese infants, were followed from birth (n = 210) to 18 months (n = 174) with anthropometry, dietary intake and feeding practices measured at seven time points. Socio-demographic data were collected from the parents at the first home visit. At 18 months iron status was examined by full blood count and plasma ferritin concentration in 129/152 (85%) of the eligible children. Iron depletion was defined as a plasma ferritin level < 10 microg/L. Iron deficiency without anaemia was defined as iron depletion plus MCV < 70fl and iron deficiency anaemia was defined as iron deficiency anaemia plus Hb < 110 g/L.


RESULTS
The prevalence of iron deficiency was iron depletion 19.4% (95% CI: 13.0%, 27.3%), iron deficiency without anaemia 3.1% (95% CI: 0.9%, 7.8%) and iron deficiency anaemia 3.9% (95% CI: 1.3%, 8.8%). Multiple regression analysis showed three significant predictors of iron deficiency: cows milk intake (negative effect), meat, fish or poultry intake (positive effect) and weight gain (negative effect). A cows milk intake > or = 650 mL/day was a risk factor for iron deficiency.


CONCLUSIONS
Prevalence of iron deficiency at 18 months was high despite appropriate infant feeding practices during the first year. Modification of the diet in the second year of life may decrease the risk of iron deficiency in Vietnamese children.
