Abstract

Among older children, neglect is linked to reduced cortical grey matter volume, whereas abuse is linked to reduced right amygdala volume. Less is known about whether similar effects of adversity are evident in infancy, a period of particularly rapid brain growth. This study evaluated whether family involvement with child protective services (CPS) was linked to differences in infant brain volumes (whole brain grey matter, cortical grey matter, right and left insular cortex, and right and left amygdala). Participants were recruited in the northeastern United States. Mothers (N = 55) reported on any family involvement with CPS as a parent. Infants completed a brain MRI between 4 and 25 months of age (M_age= 11.56 months). Family CPS involvement was associated with lower infant whole brain grey matter volume, cortical grey matter volume, and left insular cortex volume. No relations to amygdala volumes were observed. Caregiving adversity may affect cortical grey matter development during infancy, with family CPS involvement as an accessible index identifying infants at risk.

家庭保护服务参与与婴儿皮质灰质体积减少。

在年龄较大的儿童中，忽视与皮质灰质体积减少有关，而虐待与右侧杏仁核体积减少有关。在大脑发育特别迅速的婴儿期，逆境的类似影响是否明显尚不清楚。本研究评估了家庭参与儿童保护服务（CPS）是否与婴儿脑容量（全脑灰质、皮质灰质、左右岛叶皮层、左右杏仁核）的差异有关。参与者是从美国东北部招募的。母亲（N = 55）报告了作为家长参与CPS的任何家庭活动。婴儿在4 - 25个月大（11.56个月大）完成脑MRI检查。家庭CPS参与与婴儿全脑灰质体积、皮质灰质体积和左岛叶皮质体积降低有关。与杏仁核体积没有关系。照顾逆境可能会影响婴儿时期皮质灰质的发育，家庭CPS参与是识别婴儿风险的一个可访问的指标。

期刊介绍： The Infant Mental Health Journal (IMHJ) is the official publication of the World Association for Infant Mental Health (WAIMH) and the Michigan Association for Infant Mental Health (MI-AIMH) and is copyrighted by MI-AIMH. The Infant Mental Health Journal publishes peer-reviewed research articles, literature reviews, program descriptions/evaluations, theoretical/conceptual papers and brief reports (clinical case studies and novel pilot studies) that focus on early social and emotional development and characteristics that influence social-emotional development from relationship-based perspectives. Examples of such influences include attachment relationships, early relationship development, caregiver-infant interactions, infant and early childhood mental health services, contextual and cultural influences on infant/toddler/child and family development, including parental/caregiver psychosocial characteristics and attachment history, prenatal experiences, and biological characteristics in interaction with relational environments that promote optimal social-emotional development or place it at higher risk. Research published in IMHJ focuses on the prenatal-age 5 period and employs relationship-based perspectives in key research questions and interpretation and implications of findings.
