The relationship between postnatal lead (Pb) exposure and early sensorimotor development was prospectively investigated in a group of infants born to parents residing in lead-hazardous areas of Cincinnati, Ohio. Few significant relationships were found between current or cumulative infant blood Pb levels and indices of sensorimotor development during the first year of life. When important developmental covariates such as birth weight and home environment were included in the analyses, no significant relationship between Pb exposure and development remained. To date, there appears to be no evidence in these data that postnatal low-level Pb exposure increases an infant's risk for delays in early sensorimotor development.
对居住在俄亥俄州辛辛那提市铅污染危险地区的父母所生的一组婴儿，前瞻性地研究了出生后铅（Pb）暴露与早期感觉运动发育之间的关系。在出生后第一年，婴儿当前或累积血铅水平与感觉运动发育指标之间几乎未发现显著关系。当在分析中纳入出生体重和家庭环境等重要发育协变量时，铅暴露与发育之间不再存在显著关系。迄今为止，这些数据中似乎没有证据表明出生后低水平铅暴露会增加婴儿早期感觉运动发育延迟的风险。
