母亲的个性特征影响孩子的认知发展，这一观点基于压力调节理论。母亲的人格特质，如自尊，可能会缓冲母亲的压力或导致改善母婴互动，直接影响神经发育。这可以延伸到表明，母亲的个性可能会减弱或加剧其他神经毒物的影响，虽然这还没有被直接研究。我们研究了母亲的自尊是否对孩子的认知结果有直接或主要影响。我们还探讨了母亲自尊对这些儿童铅暴露与神经发育之间关系的调节作用。研究参与者包括来自墨西哥城的379对母子。数据包括母亲的库珀史密斯自尊量表，儿童的贝利婴儿发育量表（BSID）评分和社会人口信息。线性回归模型之间的关系，母亲的自尊和贝利的心理发展指数（MDI）和精神发育指数（PDI）的分数在24个月大的母亲的自尊水平分层模型。在调整后的模型中，母亲自尊每增加一点，孩子们的Bayley's MDI得分就高出0.2分（p = 0.04）。使用PDI结果观察到类似结果。此外，有证据表明，母亲的自尊减弱了铅暴露的负面影响，尽管这种相互作用没有达到传统的统计显著性水平。(C)2007年爱思唯尔公司All rights reserved.
The notion that maternal personality characteristics influence cognitive development in their children has been grounded in stress moderation theory. Maternal personality traits, such as self-esteem, may buffer maternal stressors or lead to improved maternal-child interactions that directly impact neurodevelopment. This can be extended to suggest that maternal personality may serve to attenuate or exacerbate the effects of other neurotoxicants, although this has not been studied directly. We examined whether mothers' self-esteem had a direct or main effect on their children's cognitive outcomes. We also explored the modifying effects of maternal self-esteem on the association between exposure to lead and neurodevelopment in these children. Study participants included 379 mother-child pairs from Mexico City. Data included the Coopersmith Self-Esteem Scale in mothers, children's Bayley's Scale of Infant Development (BSID) scores, and sociodemographic information. Linear regression was used to model the relationship between maternal self-esteem and the Bayley's Mental Development Index (MDI) and Psychomotor Development Index (PDI) scores at age 24 months using models stratified by levels of maternal self-esteem. In adjusted models, each point increase in maternal self-esteem was associated with children having 0.2 higher score on the Bayley's MDI (p = 0.04). Similar results were observed using the PDI outcome. Moreover, there was evidence that maternal self-esteem attenuated the negative effects of lead exposure, although the interaction fell short of conventional levels of statistical significance.
