Is Serum Magnesium Associated with Prehypertension? Two-Year Cross-sectional Study at Rural Central India

Abstract

Abstract Background: Prehypertension (HTN) raises the likelihood of developing HTN. Very few studies have been conducted on the serum magnesium responsible for causing pre-HTN. Materials and Methods: In this cross-sectional study, 300 subjects (150 cases and 150 controls) were enrolled to investigate the association between serum magnesium levels and pre-HTN. One hundred and fifty individuals with pre-HTN were compared with 150 controls without pre-HTN. All subjects had undergone anthropometric measurements such as body mass index (BMI) and waist–hip ratio along with lipid profile. Results: Levels of serum magnesium were low among the study population with pre-HTN when compared to controls without pre-HTN. Prehypertensive individuals show high BMI (24.09 ± 2.10 vs. 21.54 ± 2.02), waist–hip ratio (0.86 ± 0.08 vs. 0.82 ± 0.07), fasting blood sugar levels (103.15 ± 7.47 vs. 94.41 ± 8.21), serum triglyceride (141.12 ± 41.41 vs. 128.37 ± 23.46), and total cholesterol (175.95 ± 28.12 vs. 159.59 ± 19.03) levels when compared to controls. Multivariate logistic regression analysis was conducted which revealed a strong correlation between pre-HTN and hypomagnesemia. Conclusion: This study found a positive correlation between pre-HTN and low blood magnesium levels.
