A multi-center study on the association between serum magnesium levels and allostatic load in hemodialysis patients
Objective: Serum magnesium (Mg 2+ ) levels are associated with insulin resistance, hypertension, lipid abnormalities, and inflammation. However, limited studies have indicated the relationship between Mg 2+ and multiple system indexes. The purpose of this study was to investigate the association bet...

Summary: | Objective:
Serum magnesium (Mg
2+
) levels are associated with insulin resistance, hypertension, lipid abnormalities, and inflammation. However, limited studies have indicated the relationship between Mg
2+
and multiple system indexes. The purpose of this study was to investigate the association between Mg
2+
and allostatic load (AL) in hemodialysis patients.
Methods:
A cross-sectional survey was conducted on hemodialysis patients from different centers in Anhui Province, China, between January and December 2020. A total of 3,025 hemodialysis patients were recruited. Their clinical data were measured before hemodialysis. Information was collected by an online self-reported questionnaire and medical record. Serum Mg
2+
was divided into three groups by tertiles. A score of AL greater than or equal to 3 was defined as high AL. A binary logistic regression model was applied to examine the relationship between serum Mg
2+
and AL.
Results:
A total of 1,222 patients undergoing hemodialysis were included, 60% of whom were males (733/1,222). The mean (standard deviation) age of patients was 55.90 (12.75). The median level of serum Mg
2+
was 1.22 mmol/L. The rate of high AL levels was 23.4%. Serum Mg
2+
was negatively correlated with body mass index, fasting blood glucose (Glu), and C-reactive protein and positively correlated with high-density lipoprotein, low-density lipoprotein, total cholesterol, diastolic blood pressure (DBP), and serum phosphorus. After adjusting for gender, anxiety, diabetes, family residence, lipid-lowering agents, antihypertensive medications, albumin, and Glu, the binary logistic regression model showed that patients with lower levels of serum Mg
2+
were more likely have high AL (
OR
for the T1 group of serum Mg
2+
:1.945, 95%
CI
: 1.365–2.773, and
OR
for the T2 group of serum Mg
2+
:1.556, 95%
CI
: 1.099–2.201).
Conclusion:
Our data support the hypothesis that higher serum Mg
2+
concentrations may contribute to lower health risk in hemodialysis populations. Further randomized controlled trials and cohort studies are warranted to verify whether Mg
2+
supplementation could be part of routine examinations in hemodialysis populations. |
