RESUMO
Objective To explore the characteristics of blood uric acid levels and its correlation with calcium and phosphorus levels, and glucose and lipid metabolism in obese adolescents in weight-loss training camps. Methods In this study, 357 obese adolescents aged 12-18 were selected as the research subjects, and 135 normal-weight adolescents were selected as the controls. The body shape and blood uric acid characteristics of the subjects were measured and analyzed. Further, 59 subjects were selected from the obese adolescents for blood calcium, blood phosphorus and glucose and lipid metabolism index tests to analyze the correlation between blood uric acid level and calcium, phosphorus, and glucose and lipid metabolism indicators. Results The average blood uric acid level of obese adolescents was (527.12±122.94)μmol/L, (566.58±122.51)μmol/L for boys, and (468.35±97.79)μmol/L for girls. The blood uric acid level of the obesity group was significantly higher than that of the control group (P<0.001 for boys, P<0.05 for girls), and it was higher in boys than in girls (P<0.01). Obese adolescents with high uric acid accounted for 73.39%. The HOMA-IR of obese adolescents was 5.79±3.04. The blood uric acid level was significantly correlated with blood calcium, total cholesterol, and low-density lipoprotein cholesterol (P<0.05). Gender and low-density lipoprotein cholesterol were the main influencing factors of blood uric acid (P<0.05). Conclusion Obese adolescents have high blood uric acid levels, low calcium and high phosphorus in the body, and a higher incidence of insulin resistance. There exists a positive correlation between the blood uric acid level and the body's calcium and phosphorus metabolism and glucose and lipid metabolism in obese adolescents. Clinical monitoring of lipid metabolism indicators such as low-density lipoprotein has certain reference value for the prevention and treatment of hyperuricemia.
