Association of Maternal Serum Magnesium Level with Preterm Labour

Abstract

Background: Preterm labour is a major health problem in obstetrics. The cause of preterm labour is still unknown. The role of magnesium is also not clear. Recently, involvement of magnesium in physiological and pathological process of labour has been clearly demonstrated. Aims and Objectives: To see the association between maternal scrum magnesium level and preterm labour. Materials and Method: This cross-sectional comparative study was conducted in Department of Obstetrics and Gynecology, Sylhet M.A.G. Osmani Medical College Hospital, between January 2017 and December 2018. Thirty-five pregnant women with preterm labour were selected as case and 35 preterm age and gestational age matched pregnant women without having preterm labour were selected as control group. Serum magnesium concentration was measured. Results: The mean age (25.43 ± 4.62 years versus 24.40 ± 3.99 years; p=0.332) and the gestational age (31.31 ± 1.78 weeks versus 31.34 ± 1.84 weeks; p=0.974) did not differ between preterm labour group and control group. Serum magnesium level (mg/dl) was significantly lower in prelabour group compared to control group (0.90 ± 0.37 versus 1.69 ± 0.33; p<0.001). Conclusion: It is strongly suggested that maternal serum magnesium associated with preterm labor of unknown etiology
