Introduction: Metabolic syndrome is a cluster of symptoms following impaired glucose tolerance, adiposity, abnormal lipid profiles and hypertension. Metabolic syndrome may serve as a precursor for type II diabetes mellitus and cardiovascular diseases. Therefore, it should be considered when interpreting calcium levels, as calcium is inexpensive, readily available and can also serve as a predictor for diabetic and cardiovascular risks. Aim: To investigate the correlation of serum calcium with components of metabolic syndrome. Materials and Methods: A cross-sectional study was conducted in the Department of Biochemistry, Government Medical College and General Hospital, Aurangabad, Maharashtra, India, from January 2016 to March 2016. A total of 80 patients were divided into two groups: subjects with metabolic syndrome (group I) and subjects without metabolic syndrome (group II). Data including age and components of metabolic syndrome such as Body Mass Index (BMI), Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP), Waist Circumference (WC) and various biochemical parameters {plasma glucose, calcium, albumin, corrected calcium, total cholesterol, Triglycerides (TG), High-Density Lipoprotein (HDL) and Low-Density Lipoprotein (LDL)}. were collected and compared between the two groups. The differences in the studied variables among the groups were analysed using an Unpaired t-test. A p-value less than 0.05 was considered statistically significant. Results: In the present study, group I consisted of 23 males and 17 females with the mean±Standard Deviation (SD) age 49.88±8.7 years and group II had 19 males and 21 females with mean age 47.5±7.60 years. There were no significant differences in age, gender and blood pressure, while BMI and WC were significantly higher in group I. Serum calcium, fasting plasma glucose levels, and lipid profiles were significantly higher in subjects with metabolic syndrome compared to those without metabolic syndrome. Additionally, serum corrected calcium levels showed a positive correlation with serum TG and fasting plasma glucose (r-value=0.4, p-value=0.008), and a negative correlation with HDL-cholesterol (HDL-C) (r-value=- 0.3, p-value=0.03). Conclusion: In the present study, serum total calcium was found to be positively associated with metabolic syndrome. Estimation of serum calcium can help predict the risk of developing cardiovascular diseases or diabetes mellitus, which are associated with the metabolic syndrome.
