The first months of life are critical for establishing neural connections relevant for social and cognitive development. Yet, the United States lacks a national policy of paid family leave during this important period of brain development. This study examined associations between paid leave and infant electroencephalography (EEG) at 3 months in a sociodemographically diverse sample of families from New York City (N = 80; 53 males; 48% Latine; data collection occurred 05/2018-12/2019). Variable-centered regression results indicate that paid leave status was related to differences in EEG power (ps < .02, R s > .12). Convergent results from person-centered latent profile analyses demonstrate that mothers with paid leave were 7.39 times as likely to have infants with EEG profiles characterized by increased higher-Hz power (95% CI, 1.9-36.9), potentially reflecting more mature patterns of brain activity.
生命的头几个月对于建立与社会和认知发展相关的神经连接至关重要。然而，美国在大脑发育的这个重要时期缺乏带薪家庭假的国家政策。本研究在纽约市的一个社会人口统计学多样化的家庭样本中（N=80；53 名男性；48%拉丁裔；数据收集于 2018 年 5 月至 2019 年 12 月），考察了带薪休假与 3 个月大婴儿脑电图（EEG）之间的关联。变量中心回归结果表明，带薪休假状况与 EEG 功率差异有关（ps<.02，R s>.12）。从个体中心潜在剖面分析得出的一致结果表明，有带薪休假的母亲使婴儿具有 EEG 特征的可能性增加了 7.39 倍，这些特征表现为更高的高频功率（95%置信区间，1.9-36.9），这可能反映了更成熟的大脑活动模式。
