为研究儿童体成分与血清甲状腺激素及锌、铜之间的关系，按体脂百分比将８１名８～１２岁儿童分为肥胖组、正常组和消瘦组，并进行甲状腺激素及血清锌、铜的测定。结果表明，肥胖组游离三碘甲状腺原氨酸（ＦＴ３）显著高于其他两组，正常组高于消瘦组。体成分各指标、血清甲状腺激素、血清锌和铜的相关分析可见：体脂肪含量与ＦＴ３有正相关关系。本次实验未发现８～１２岁儿童体成分、甲状腺激素和锌、铜之间有相关关系
To study the relationship between body composition and serum thyroid hormones and zinc and copper in children, 81 children aged 8-12 years were divided into obesity group, normal group and emaciated group according to percentage of body fat. Thyroid hormone and serum zinc, copper The determination. The results showed that free triiodothyronine (FT3) in obesity group was significantly higher than the other two groups, and the normal group was higher than the emaciation group. Body composition of the indicators, serum thyroid hormone, serum zinc and copper-related analysis shows: body fat content and FT3 have a positive correlation. The experiment did not find the body composition of children aged 8 to 12, thyroid hormone and zinc, copper have a correlation between
