ABSTRACT
We measured selenium, zinc, copper and manganese concentrations in the human milk of Korean mothers who gave birth to preterm infants, and compared these measurements with the recommended daily intakes. The samples of human milk were collected postpartum at week-1, -2, -4, -6, -8, and -12, from 67 mothers who gave birth to preterm infants (< 34 weeks, or birth weight < 1.8 kg). All samples were analyzed using atomic absorption spectrophotometry. The concentrations of selenium were 11.8 +/- 0.5, 11.4 +/- 0.8, 12.7 +/- 0.9, 11.4 +/- 0.8, 10.8 +/- 0.9, and 10.5 +/- 1.3 microg/L, zinc were 7.8 +/- 0.5, 9.1 +/- 0.8, 7.2 +/- 0.9, 8.0 +/- 0.8, 7.4 +/- 0.9, and 6.6 +/- 1.2 mg/L, copper were 506 +/- 23.6, 489 +/- 29.4, 384 +/- 33.6, 356 +/- 32.9, 303 +/- 35.0, and 301 +/- 48.0 microg/L and manganese were 133 +/- 4.0, 127 +/- 6.0, 125 +/- 6.0, 123 +/- 6.0, 127 +/- 6.0, and 108 +/- 9.0 microg/L at week-1, -2, -4, -6, -8, and -12, respectively. The concentrations of selenium and zinc meet the daily requirements but that of copper is low and of manganese exceeds daily requirements recommended by the American Academy of Pediatrics, Committee on Nutrition.
