儿童体成分与甲状腺激素关系的研究

Relationship between Body Composition and Thyroid Hormone in Children Aged 8～12 Years

对81名的8～12岁男、女学生进行了甲状腺激素的测定，并按体脂百分比分为肥胖组、中等组、消瘦组。肥胖组游离三碘甲状腺原氨酸（FT3）值显著高于其它两组（P＜0.05），中等级高于消瘦组（P＜0.05）。对体成分各指标、游离甲状腺激素（FT4）水平的相关分析显示：体脂肪食量与FT3有正相关关系（P＜0.01）。

According to the percentage of body fat(BFP), 81children were divided into obese group. normal group and thin group. Among all of children. free 3, 5, 3' - triiodothyronine (FT3 ). freethyroxine (FT4 ) and thyroidstimulating hormone (TSH) inserum were measured. The results showed that the differences were not statistically significant in the levels of measured hormones except for FT3 among three groups. FT3 level was highest in obese group, and higher in normal group than in thin group (P<0. 05). A significant positve corrclation (P<0. 01) was found between FT3 and BFP.
