本文对81名肥胖和正常儿童少年的几项身体指标（包括肥胖度、BMI、体围、皮褶厚度）及血脂作了检测。结果表明：儿童少年肥胖各项身体指标均显著增加；肥胖儿TC、TG、LDL，－C、LDL，－C/HCL，－C、Al显著升高，且与肥胖程度正相关，HDL，－C/TC：显著降低且与肥胖程度负相关；脂肪分布与血脂变化密切相关。结果提示肥胖可影响血脂水平，肥胖儿发生动脉粥样硬化的危险性增高。BMI可作为评价肥胖的较好参考指标。 In this paper, 81 obesity and normal children and adolescents several physical indicators (including obesity, BMI, body circumference, skinfold thickness) and blood lipids were detected. The results showed that all body indexes of juvenile obesity increased significantly. The levels of TC, TG, LDL, C, LDL, C / HCL, C and Al in obesity children were significantly increased, C / TC: significantly reduced and negatively correlated with the degree of obesity; fat distribution is closely related to changes in blood lipids. The results suggest that obesity can affect blood lipid levels, and the risk of atherosclerosis in obese children increases. BMI can be used as a good reference to evaluate obesity.
