Serum uric acid level and its related factors in school-age children with obesity / 临床儿科杂志

ABSTRACT

Objectives To investigate the serum uric acid level and its related factors in obese children. Methods Obese children were selected from all pupils (ages 7-14) of 3 primary schools. Age-and sex-matched children with normal body mass index (BMI) were chosen as normal controls. Fasting venous blood samples were collected to detect uric acid (UA), glucose (GLU), total cholesterol (CHOL), triacylglycerol (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipopro-tein cholesterol (LDL-C). Results Sixty-eight (2.2%) obese children (57 boys and 11 girls) were detected from 3 000 children. Compared with 136 normal controls, the blood pressure (BP), levels of UA, CHOL, TG and LDL-C, and waist circumference (WC) were higher while HDL-C was lower in obese children (P<0.05). The detection rate of hyperuricemia in obese children (35.3%) were signiifcantly higher than that in normal controls (5.9%) (P<0.05). UA was positively related with WC, BMI, BP and TG, negatively related with HDL-C. Conclusions Obesity can lead to higher serum UA, higher BP and abnormal lipid metabolism. The level of serum UA was correlated with BP and abnormal lipid metabolism.
