Breastfeeding and Red Meat Intake Are Associated with Iron Status in Healthy Korean Weaning-age Infants.
J Korean Med Sci. 2017 Jun; 32(6):974-984.JK

Abstract

The present study investigated risk factors for iron deficiency (ID) and iron deficiency anemia (IDA) during late infancy, including feeding type and complementary feeding (CF) practice. Healthy term Korean infants (8-15 months) were weighed, and questionnaires regarding delivery, feeding, and weaning were completed by their caregivers. We also examined levels of hemoglobin, serum iron/total iron-binding capacity, serum ferritin, and mean corpuscular volume (MCV). Among 619 infants, ID and IDA were present in 174 infants (28.1%) and 87 infants (14.0%), respectively. The 288 infants with exclusively/mostly breastfeeding until late infancy (BFL) were most likely to exhibit ID (53.1%) and IDA (28.1%). The risk of ID was independently associated with BFL (adjusted odds ratio [aOR], 47.5; 95% confidence interval [CI], 18.3-122.9), male sex (aOR, 1.9; 95% CI, 1.2-2.9), fold weight gain (aOR, 2.6; 95% CI, 1.5-4.6), and perceived inadequacy of red meat intake (aOR, 1.7; 95% CI, 1.0-2.7). In addition to the risk factors for ID, Cesarean section delivery (aOR, 1.9; 95% CI, 1.1-3.2) and low parental CF-related knowledge (aOR, 2.8; 95% CI, 1.5-5.2) were risk factors for IDA. In conclusion, prolonged breastfeeding and perceived inadequacy of red meat intake may be among the important feeding-related risk factors of ID and IDA. Therefore, more meticulous education and monitoring of iron-rich food intake, such as red meat, with iron supplementation or iron status testing during late infancy if necessary, should be considered for breastfed Korean infants, especially for those with additional risk factors for ID or IDA.
