摘要

童年时期的铅暴露与包括反社会/攻击行为在内的多种不良后果有关。然而,不同亚型的反社会行为具有不同的神经生物学相关性,目前尚不清楚铅暴露是否与特定亚型的攻击性行为有关。本研究旨在探讨儿童期血铅水平(BLL)与主动和被动攻击行为之间的关系。此外,鉴于之前的研究发现铅暴露的影响存在性别差异,我们还研究了这些关系中是否存在性别差异。我们对中国 818 名 10-13 岁青少年(47.2% 为女孩)进行了血铅含量评估,并发放了 "反应性攻击问卷"。结果显示,BLL 与反应性攻击相关,但与主动性攻击无关。在预测攻击行为方面,铅中毒水平与性别之间存在明显的交互作用;铅中毒水平较高的男孩在主动和被动攻击行为方面的得分均高于铅中毒水平较低的男孩,但女孩则不存在这些差异。这些研究结果表明,铅暴露可能会对反社会行为产生广泛影响,但男孩可能比女孩更容易受到影响。这些发现可为确定潜在干预目标的保护性因素提供启示。

Association between lower-level of environmental lead exposure and reactive and proactive aggression in youth: Sex differences.

Lead exposure during childhood has been associated with a variety of negative outcomes, including antisocial/aggressive behavior. However, different subtypes of antisocial behavior have been found to have different neurobiological correlates, and it is unclear whether lead exposure is related to specific subtypes of aggressive behavior. The objective of the study was to examine relationships between childhood blood lead levels (BLL) and proactive and reactive aggression. Further, given prior findings of sex differences in the effects of lead exposure, we examine whether there are sex differences in these relationships. In a sample of 818 youth (47.2% girls) ages 10-13 in China, we assessed BLL and administered the Reactive Proactive Aggression Questionnaire. Results show that BLLs were associated with reactive, but not proactive aggression. There was a significant interaction between BLL and sex in predicting aggression; boys with higher BLL scored higher in both proactive and reactive aggression than boys with lower BLL, but these differences were not present for girls. These findings suggest that lead exposure may have broad effects on antisocial behavior, but that boys may be more susceptible than girls. These findings may provide insights to identifying protective factors that could be potential targets for intervention.
