Abstract

Background
The interaction between calcium and magnesium as a risk modifier for insulin resistance may be largely overlooked because the strict regulatory system in blood has been thought to maintain such homeostatic interactions under tight control. This study aimed to investigate the relationship between the calcium-magnesium ratio in hair with the triglyceride glucose index (TyG index) and triglyceride/HDL-cholesterol ratio (TG/ HDL ratio) among overweight or obese Korean individuals.
Methods
This cross-sectional study included 56 participants fulfilling the inclusion criterion of a body mass index of 23 kg/m² or more. Intra-abdominal visceral adipose tissue (VAT) was measured by fat measurement computed tomography, while calcium and magnesium levels were measured by hair mineral analysis. A high TyG index and a high TG/HDL ratio were defined as >9.3 and >4.0, respectively (>75th percentile). Using multiple logistic regression analysis, we examined the associations between the TyG index, TG/HDL ratio, and calcium–magnesium ratio in hair.
Results
The mean age, body mass index, and VAT were 45.3 years, 28.5 kg/cm² , and 137.4 cm² , respectively. Compared to the controls, the odds ratios (95% confidence intervals) for a high TyG index and a high TG/HDL ratio were 16.03 (1.32–194.23) and 9.98 (1.05–94.98) per one increment of log (calcium-magnesium ratio), respectively, after adjusting for age, sex, body mass index, visceral adipose tissue, white blood cell count, total cholesterol, hypertension medication, diabetes medication, and dyslipidemia medication.
Conclusion
We found that the calcium-magnesium ratio in hair was positively and independently associated with the TyG index and TG/HDL ratio.
