Hemoglobin levels and iron intakes of infants attending selected child health centres in the city of Toronto.

An investigation of the hemoglobin levels of infants in potentially high-risk categories demonstrated the possibilities of a public health program of screening and referral for anemia. Blood samples for hemoglobin determinations and particulars of 24-hour dietary intakes were obtained for 252 infants between the ages of 6 and 18 months at seven child health centres in the City of Toronto. Twenty-nine percent of the infants had hemoglobin levels below 10 g./100 ml. of blood. Problems in the collection and analysis of dietary data limited the interpretation of iron intakes.
