目的:探讨正常足月儿血清甲状腺激素水平与早期体格生长发育的关系。方法:对56例正常足月儿于生后4周时测定其身长、体重,计算其每日身长增值和每日体重增值,同时用化学发光法测其血清甲状腺激素。结果:正常足月儿出生体重和出生身长与TT3均呈正相关(P<0.01,P<0.05),而与TT4、FT4、FT3、TSH无直线相关关系(P>0.05)。婴儿每日体重增值、每日身长增值与血清TT3、TT4、FT4、FT3、TSH水平无直线相关关系(P>0.05)。结论:婴儿甲状腺激素水平的差异可持续到生后4~5周。在婴儿早期,尤其是在头1个月,甲状腺激素水平并不是影响婴儿体格生长发育的主要因素。
Objective: To investigate the relationship between serum thyroid hormones and early physical growth in normal term infants. Methods: The body length and body weight of 56 normal term children were measured at 4 weeks after birth. The daily growth and weight gain were calculated. The levels of serum thyroid hormones were measured by chemiluminescence. Results: The normal term birth weight and birth length were positively correlated with TT3 (P <0.01, P <0.05), but not with TT4, FT4, FT3 and TSH (P> 0.05). There was no linear correlation between the daily gain of body weight, daily growth and serum TT3, TT4, FT4, FT3 and TSH levels (P> 0.05). Conclusions: Differences in infant thyroid hormone levels can last 4 to 5 weeks after birth. In early infancy, especially in the first month, thyroid hormone levels are not the main factors affecting the growth and development of infants.
