Abstract

Introduction: The hippocampus has a significant role in memory, learning, and cognition. Although hippocampal size is highly susceptible to family socioeconomic status (SES) and associated stress, very little is known on racial and ethnic group differences in the effects of SES indicators on hippocampus volume among American children.

Purpose: This study explored the multiplicative effects of race, ethnicity, and family SES on hippocampus volume among American children.

Methods: Using data from the Adolescent Brain Cognitive Development (ABCD), we analyzed the functional Magnetic Resonance Imaging (fMRI) data of 9390 9-10 years old children. The main outcome was hippocampus volume. The predictor was parental education. Subjective family SES was the independent variable. Age, sex, and marital status were the covariates. Racial and ethnic group membership were the moderators. To analyze the data, we used regression models.

Results: High subjective family SES was associated with larger hippocampus volume. This effect was significantly larger for Whites than Black families.

Conclusions: The effect of subjective family SES on children's hippocampus volume is weaker in Black than White families.

种族、民族、家庭社会经济地位与儿童海马体积的关系。

海马在记忆、学习和认知中起着重要的作用。虽然海马体大小高度容易受到家庭社会经济地位(SES)和相关压力的影响，但在美国儿童中，社会经济地位指标对海马体体积影响的种族和民族差异知之甚少。目的:本研究探讨种族、民族和家庭经济地位对美国儿童海马体积的倍增效应。方法:利用青少年脑认知发展(ABCD)数据，对9390例9 ~ 10岁儿童的功能磁共振成像(fMRI)数据进行分析。主要观察指标为海马体积。预测因素是父母教育。主观家庭经济地位为自变量。协变量为年龄、性别和婚姻状况。种族和民族成员是调节者。为了分析数据，我们使用回归模型。结果:主观家庭SES高与海马体积大相关。这种影响在白人家庭中明显大于黑人家庭。结论:主观家庭经济地位对儿童海马体积的影响在黑人家庭弱于白人家庭。
