摘要
目的探讨成人血清FT3，FT4，TSH随年龄增长而发生的变化，以及有无性别差异。方法对体检中心筛选符合标准的体检人员180人，测定其游离三碘甲状腺原氨酸（FT3），游离四碘甲状腺原氨酸（FT4），促甲状腺素（TSH）。结果FT3在20-69岁间以每年0．77％的速度逐渐下降，FT4以每年0．87％的速度逐渐下降，TSH在20～39岁间无明显改变，40岁后以每年1．72％的速度逐渐上升。男性组的FT3，FT4较女性组的高，而TSH较女性组低，且统计学有意义。结论FT3，FT4随着年龄的增长逐渐下降，TSH于40岁后逐渐增加；男性FT3，FT4较女性高，TSH较女性组低。
Objective To investigate the age-related changes of serum FT3 , FT4, TSH, and the effect of gender on them. Methods Sera were obtained from 87 males and 93 females （ age 20 to 69 years） in the medial examination certer. Testing their serum free triidothyronine （ FT3 ） , free thyroxin （ FT4 ）, thyrotropic-stimulating hormone （TSH）. Results FT3, FT4 progressively decreased from 20 to 69 years, FT3 decreased at the rate of 0.77% per year, FT4 decreased at the rate of 0.87% per year; TSH didn＇t chang from 20 to 39 years, and progressively increased with aging by 1.72% per year after 40 years. The males had higher FT3 ,FT4 and lower TSH than the females. Conclnsion This cross-section study susgests FT3 , FT4 progressively decrease with aging, TSH progressively increase after 40 years. The males had higher FT3 , FT4 , and lower TSH than the females.
