Abstract: 

Human milk is considered as the optimal source of nutrients for infants and magnesium (Mg) accounts for 1.43% to 2.45% of total mineral mass of milk. The assessment of milk Mg constituent is important for nutritional management during early life. Since, in Iran, there were no data on the Mg content of milk of mothers, in the present study, we studied and compared Mg levels in milk of mothers with small (SBW) and appropriate birth weight (ABW) infants; also changes during the lactation period were evaluated. This study was performed during the first 6 months of life on 25 mothers with ABW and 18 mothers with SBW infants in anurban area of Iran. Mothers with chronic illness, multiple pregnancies, toxemia, HIV infection, hepatitis and smoking were excluded. All mothers had a normal length of pregnancy (>37 weeks). A dry ashing procedure was used for the digestion of milk, and concentration of Mg was analyzed by flame atomic absorption spectrometry. The mean weight was significantly (p<0.001) lower in the SBW infants (2.18±0.25 kg) compared to ABW infants (3.20±0.34 kg). The mean content of Mg in milk from the mothers with ABW infants at the first, third and sixth months were 28.83±7.07, 29.91±4.83, 29.10±5.50 mg/L, respectively. There was no significant difference between Mg levels of milk from mothers with ABW and SBW deliveries. The present data suggest that Mg intake through milk is not a matter of concern in small birth weight.
