RESUMO
The aim of study was to compare the serum level of magnesium in mothers having low birth weight with those having normal birth weight neonates. In a case-control study, women who delivered low birth weight neonate [cases], compared with normal birth weight [controls] in serum concentration of magnesium. Blood samples collected within 24 h after delivery. Concentration of magnesium assessed by standard atomic absorption spectro-photometry. Multiple linear regression analysis was performed to control of potential confounding variables. A total of 116 mothers [67 cases and 49 control] were studied. Mothers in two groups did not differ in age, body mass index, and socioeconomic or demographic factors. Maternal magnesium concentration did not differ between two groups 0.86 +/- 0.11 m. mol/l versus 0.94 +/- 0.22 m.mol/l respectively [P = 0.09]. There is no significant difference between serum magnesium levels of low birth weight infants' mother and normal weight infants' mother
