研究人员对一组新西兰出生的9岁儿童进行了牙本质铅水平与认知能力测量之间的关系研究。牙本质铅测量与所有认知能力测量，包括智力、单词识别和教师对学校表现的评分之间存在微小、一致和稳定的相关性。在调整了混杂协变量、样本选择因素和可能的反向因果效应的影响后，智力和牙本质铅水平之间的相关性变得不显著。然而，在对混杂来源进行调整后，牙本质铅值和所有学校表现指标之间仍然存在着微小但在统计学上显著的相关性。结论是，来自这项分析的证据的份量支持这样的假设，即低水平的铅暴露可能对儿童的成就水平产生有害影响。
The relationship between dentine lead levels and measures of cognitive ability was examined for a birth cohort of New Zealand children studied until the age of 9. There were small, consistent and stable correlations between dentine lead measures and all measures of cognitive ability including intelligence, word recognition and teacher ratings of school performance. After adjustment for the effects of confounding covariates, sample selection factors and possible reverse causal effects, the correlations between intelligence and dentine lead levels became non-significant. However, small but statistically significant correlations persisted between dentine lead values and all measures of school performance after adjustment for sources of confounding. It is concluded that the weight of the evidence from this analysis favours the hypothesis that low level lead exposure may have deleterious effects on levels of achievement in children.
