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.%目的探讨肥胖儿童血尿酸水平及相关因素。方法从三所小学，7~14岁小学生中筛查出肥胖儿童；选取年龄及性别相匹配、体质指数（BMI）正常的儿童作为对照。抽取空腹静脉血检测尿酸（URIC）、葡萄糖（GLU）、总胆固醇（CHOL）、三酰甘油（TG）、高密度脂蛋白胆固醇（HDL-C）、低密度脂蛋白胆固醇（LDL-C）。结果共调查3000名儿童，筛查出肥胖儿童68例，检出率为2.2%（68/3000），其中男孩57名，女孩11名。与136例正常对照儿童比较，肥胖组儿童的血压、URIC、CHOL、TG、LDL-C、腰围均增高，而HDL-C降低，差异均有统计学意义（P<0.05）。肥胖儿童高尿酸血症检出率为35.3%，高于正常对照儿童5.88%，差异有统计学意义（P<0.05）。URIC与腰围、BMI、血压、TG呈正相关，与HDL-C负相关。结论
