The Relationship Between Maternal Serum Levels of Calcium, Phosphorus and Magnesium with Preterm Labor: A Case-Control Study

Introduction: Preterm delivery is one of the essential midwifery problems, which causes a large proportion of infant mortality even in advanced societies. Despite advances in pregnancy care, the frequency of preterm delivery has not decreased. This study aimed to determine the relationship between serum calcium, phosphorus, and magnesium level with preterm labor in pregnant women. Methods: In this descriptive-analytic study, 40 mothers with full-term and 40 mothers with preterm labor were enrolled. Serum levels of calcium, phosphorus, and magnesium were compared and compared. Data were analyzed by SPSS 19 software using statistical tests. The significance level was considered 0.05. Results: In the present study, mean (standard deviation) serum calcium, phosphorus, and magnesium levels respectively were 8.65 (0.72), 3.65 (0.57), and 1.89 (0.47). It was reported mmol / l and in mothers with term labor 8.8 (0.55), 3.53 (0.71) and 1.79 (0.17) mmol / lit, respectively. There was no significant difference between the two groups in the salts. Conclusions: The results of our study showed no difference in serum levels of calcium, phosphorus, and magnesium in the two groups of women with the term and preterm labor. However, further studies with a higher sample size are needed.
