Background Obesity is a chronic condition that is associated with disturbances in the metabolism of zinc. Therefore, the aim of this study was to investigate the relationship between serum zinc level and different clinical and biochemical parameters in obese individuals. Patients and methods Twenty-four individuals with BMI more than 30 kg/m 2 and 14 healthy controls (BMI < 24 kg/m 2 ) were assessed for BMI and waist circumference using anthropometric measurements. Colorimetric tests were carried out for the determination of zinc in serum. Results In this study, BMI and waist circumference were higher in the obese group than in the control group (P < 0.05). The mean serum zinc levels were 92 ± 31.1 and 101 ± 70 μg/dl in the obese group and control group (P > 0.05), respectively. There was a significant negative correlation between the serum zinc level and BMI, waist circumference and low-density lipoprotein (P < 0.05). Conclusion Plasma zinc concentration in obese individuals showed an inverse relationship with the waist circumference and BMI as well as serum low-density lipoprotein-cholesterol and correlated positively with high-density lipoprotein.
