Background and aims: Since the prevalence of vitamin D deficiency is high in some countries, such as Iran, and the trend of hypertension and obesity is increasing, this study aimed to investigate the serum level of vitamin D and explore its correlation and association with obesity, blood pressure, fasting blood sugar (FBS), and lipid profile. Our hypothesis is that serum vitamin D levels are associated with risk factors for cardiometabolic disease such as hypertension. Methods: The results of this article were extracted from a cross-sectional study with a sample size of 720 people in the winter of 2020. The serum level of 25 OH vit D was measured using the ELISA method. In addition, lipid profiles were measured using the Auto Analyzer photometry method. Results: Serum levels of vitamin D (25 (OH) vitamin D) were significantly higher in the control group compared to the case group (29.5 ± 16.3 vs. 26.7 ± 14.5; P-value = 0.016). The significant association between body mass index (BMI) and FBS (Beta unadjusted:0.024, 95%CI 0.009:0.038; Beta adjusted:0.020,95%CI 0.005:0.034), and triglyceride (Beta unadjusted:0.009, 95%CI 0.006:0.012; Beta adjusted:0.008,95%CI 0.005:0.011), and an inverse association HDL-C (Beta unadjusted:-0.079,95%CI -0.123:-0.036; Beta adjusted:-0.065,95%CI -0.111:-0.019) were seen in both unadjusted and adjusted models. Conclusion: In conclusion, we report that obese people had significantly lower serum vitamin D levels than normal-weight people. There is also a significant correlation between BMI and blood pressure.
