Policy statement on iron deficiency in pre-school-aged children.

ABSTRACT

AIM: We aimed to develop policy in relation to three areas (i) the diagnosis of iron deficiency; (ii) maternal-infant issues and the prevention of iron deficiency; and (iii) the treatment of iron deficiency. METHODS: Within each of these topic areas we completed a literature review and developed recommendations to help direct activities of the Royal Australasian College of Physicians, update paediatricians and guide clinical practice. RESULTS: Iron deficiency can be defined using cut-off values for laboratory measures of iron status or, if an intercurrent infection is not present, by demonstrating a response to a therapeutic trial of iron. The appropriate measures of iron status vary depending upon the presence of intercurrent infection. Full-term babies are born with iron stores sufficient to meet their needs to age 4-6 months but premature infants are not. After age 6 months infants are dependent upon dietary iron from complementary foods even with continued breastfeeding. Infants <33 weeks gestation or <1800 g birthweight should receive iron from 4 weeks of age. In most settings recommended treatment of iron deficiency is with oral ferrous sulphate as a single or twice daily dose of between 3 and 6 mg/kg/day. CONCLUSIONS: Iron deficiency is prevalent and an important determinant of child health. Precise and accurate diagnosis remains challenging. Iron supplementation is required for premature and low-birthweight infants. Oral iron salts remain the recommended treatment of choice in most instances.
