家庭社会经济地位（SES）与儿童的认知发展密切相关，过去的研究报告了整个童年时期神经认知技能和大脑结构的社会经济差异。在其他研究中，双语与一生中的认知优势和大脑结构差异有关。本研究的目的是同时研究家庭社会经济地位和双语使用与儿童时期大脑结构和认知技能之间的联合和独立关联。对儿科影像、神经认知和遗传学 (PING) 研究的一部分数据进行了分析；倾向评分匹配建立了具有相似社会人口特征（M 年龄 = 13.5，范围 = 3-20 岁）的单语和双语用户的相等样本（N = 562）。当所有年龄段的人都崩溃时，SES 与大脑结构和认知技能有关。当按年龄组检查差异时，大脑结构与青春期的收入和双语使用显着相关，但在儿童早期则不然。此外，在青春期，双语使用与 SES 之间存在显着的相互作用，较高 SES 背景的语言组之间的皮质表面积 (SA) 没有差异，但与 SES 匹配的单语者相比，来自较低 SES 家庭的双语用户的 SA 显着增加。这些结果表明 SES 和双语言使用与大脑发育之间存在独立和相互作用的关联。据我们所知，这是第一项同时研究儿童和青少年时期双语使用和大脑结构社会经济差异的研究。
Family socioeconomic status (SES) is strongly associated with children’s cognitive development, and past studies have reported socioeconomic disparities in both neurocognitive skills and brain structure across childhood. In other studies, bilingualism has been associated with cognitive advantages and differences in brain structure across the lifespan. The aim of the current study is to concurrently examine the joint and independent associations between family SES and dual-language use with brain structure and cognitive skills during childhood. A subset of data from the Pediatric Imaging, Neurocognition and Genetics (PING) study was analyzed; propensity score matching established an equal sample (N = 562) of monolinguals and dual-language users with similar socio-demographic characteristics (M age = 13.5, Range = 3–20 years). When collapsing across all ages, SES was linked to both brain structure and cognitive skills. When examining differences by age group, brain structure was significantly associated with both income and dual-language use during adolescence, but not earlier in childhood. Additionally, in adolescence, a significant interaction between dual-language use and SES was found, with no difference in cortical surface area (SA) between language groups of higher-SES backgrounds but significantly increased SA for dual-language users from lower-SES families compared to SES-matched monolinguals. These results suggest both independent and interacting associations between SES and dual-language use with brain development. To our knowledge, this is the first study to concurrently examine dual-language use and socioeconomic differences in brain structure during childhood and adolescence.
