目的:探讨宫内低水平铅暴露对新生儿体格发育的影响。方法:于2000年3月～9日,对我院及乌鲁木齐市妇幼保健院出生的139例新生儿汉族80例,维吾尔族59例,进行脐血铅测定,并在新生儿出血1小时内测量其体重、身高、头围、左上臂围。结果:(1)139例新生儿脐血铅10～329(65.08±43.88)μg/L,其中维族新生儿脐血铅大于汉族(p<0.05)。血铅≥100μg/L者49例,占35.25％。(2)新生儿脐血铅和新生儿体重、身高、头围呈负相关(p<0.01)。结论:宫内低水平铅暴露对新生儿的体格发育可能具有不利影响。
Objective: To investigate the effect of intrauterine low level lead exposure on the physical development of neonates. Methods: From March to September 2000, 80 newborns of Han nationality and 59 Uighur born in our hospital and Urumqi MCH hospital were enrolled in this study. Cord blood lead levels were measured and measured within 1 hour of neonatal bleeding Its weight, height, head circumference, left arm circumference. Results: (1) Umbilical blood lead levels in 139 neonates were between 10 and 329 (65.08 ± 43.88) μg / L, of which Umbilical cord blood lead of Uighur newborns was higher than that of Han nationality (p <0.05). Blood lead ≥ 100μg / L in 49 cases, accounting for 35.25%. (2) Neonatal cord blood lead and neonatal weight, height, head circumference was negatively correlated (p <0.01). CONCLUSIONS: Intrauterine low levels of lead exposure may have adverse effects on the physical development of newborns.
