Identifying the neural processes that underlie the association between children's early adverse experiences and cognitive development could inform more effective intervention strategies. The goal of the current study (data collected 2015–2021) was to examine relations among early experiences at 6 months, electroencephalography (EEG) theta power at 6 months and 2 years, and cognitive outcomes at 5 years in Bangladeshi children (N = 115; 67 females). Results revealed that better nutritional status was associated with a slower increase in theta power from 6 months to 2 years and higher cognitive scores at 5 years. Higher frontocentral theta power at 2 years was related to better cognition at 5 years but did not mediate the association between nutritional status and cognition.

孟加拉国儿童的脑电图 θ 功率：与早期经历和认知结果的关联

确定儿童早期不良经历与认知发展之间关联的神经过程可以为更有效的干预策略提供信息。本研究（2015-2021 年收集的数据）的目标是检查孟加拉国儿童 6 个月时的早期经历、6 个月和 2 年时的脑电图 （EEG） θ 功率以及 5 岁时的认知结果之间的关系（N = 115;67 名女性）。结果显示，较好的营养状况与 6 个月至 2 岁 θ 功率增加较慢以及 5 岁时认知评分较高有关。2 岁时较高的额中央 θ 功率与 5 岁时更好的认知有关，但不介导营养状况与认知之间的关联。
