目的 :了解低出生体重儿 (L BWI)并甲状腺功能 (甲功 )异常婴儿的体格与智力发育情况。方法 :对 6 0例存活的婴儿于其出生后 40～ 5 6周时随访 ,采用 Gesell发育诊断方法检测发育商 (DQ) ,同时测量身体发育值。结果 :有病例 16 .7%身高、体重和 18.3%头围生长落后 ,DQ在中下及其以下水平者占 33.3% ;DQ与甲功变化形式与病危程度有关。结论 :L BWI并甲功异常的婴儿 ,其出生体重越低 ,病情越重 ,其体格与智力发育落后发生率越高 Objective: To understand the physical and mental development of infants with low birth weight (L BWI) and abnormal thyroid function (thyroid function). Methods: Totally 60 surviving infants were followed up 40-56 weeks after birth. Gesell developmental diagnostic method was used to detect the developmental quotient (DQ), meanwhile, the body development was measured. Results: There were 16.7% of patients with height, weight and 18.3% head circumference growth and backwardness, 33.3% of whom had DQ at or below the middle and lower levels. The changes of DQ and KA were related to the severity of the disease. Conclusions: The infant with L BWI and abnormal thyroid function has a lower birth weight, more serious illness and a higher prevalence of physical and mental retardation
