Thyroid function in the elderly has been a matter of discussion. The universe of the present study includes males and females 36 hospitalized with an average age of 72.97 +/- 8.70 years (group I) and 36 ambulatory asymptomatic elderly with 69.81 +/- 8.55 years of age (group II). Serum levels of T3, T4, T4L and TSH were measured in both groups. Mean values of T3 were significantly lower in the hospitalized patients than in the control group. The difference persisted on both, males and females, analyzed separately. Mean values of T4L were significantly lower in women of group II, while mean values of T3 were significantly lower in men of group I. The comparison of thyroid function tests in male and female showed that serum values of T3 and T4 were significantly lower in men of group I. By dividing results in age categories, serum levels of T4L in group II were significantly lower in the age group of 70 to 79 and 80 to 89. Thyroid function tests in asymptomatic ambulatory elderly tend to be normal, whereas the hospitalized patients showed a high proportion of alterations.
老年人的甲状腺功能一直是个讨论的话题。本研究的对象包括36名住院患者（平均年龄72.97±8.70岁，I组）和36名门诊无症状老年人（平均年龄69.81±8.55岁，II组），涵盖男性和女性。两组均检测了血清T3、T4、T4L和TSH水平。住院患者的T3均值显著低于对照组。分别对男性和女性进行分析时，该差异均存在。II组女性的T4L均值显著较低，而I组男性的T3均值显著较低。男性和女性甲状腺功能检查的比较显示，I组男性的血清T3和T4值显著较低。按年龄类别划分结果，II组70至79岁和80至89岁年龄组的血清T4L水平显著较低。无症状门诊老年人的甲状腺功能检查往往正常，而住院患者则有较高比例的异常。
