Abstract - Obesity is one of the principle preventable reasons for death. extra than forty % of Iraqis be afflicted by weight problems (obesity). is that it is excessive weight gain with excess body fat. This causes the patient to be exposed to several diseases. (weight problems) is measured in lots of ways, the most crucial of which is referred to as (BMI - body mass index), that's a tool for calculating weight in relation to frame height. someone is overweight if this indicator has a fee of 30 or more. Methods: The study included healthy natural subjects as a comparison group (control) and they were (61 samples) Including (32) females and (29) males, and their ages ranged (3_15) years, and Patients Group (59 blood samples) were obtained they range in age (2_17) years, Included (35) males, (24) females. Samples were collected from the patients reviewed at [Al Khayal Hospital].Level of antioxidants was assessed by estimation in the serum convergences of complete cancer prevention agents limit (TAC) by UV spectrophotometric strategy. also, Serum minor components (Zn, Cu and Fe) assessed by Atomic Absorption Spectroscopy (AAS .) The Statistical Analysis System-SAS (2012) program was utilized to distinguish the impact of contrast factors in study boundaries. T-test was utilized to huge look at between implies. in this examination. Result: Our study observed significantly elevated concentrations of (TAC) (p < 0. 01)in the control than patient. Investigation of serum minor components (Zn, Cu and (Fe) found that the mean estimations of Zn, Fe, Cu, were (106.52 ± 0.76) and (70.44 ± 0.76), and (65.85 ± 1.97 ) μg/dl for the patient and (53.73 ± 2.11), (31.16 ± 0.87), and (91.12 ± 3.00) μg/dl for the controls, thusly. There was a significant contrast in minor components the patients and controls (p < 0.01).
