Objective To explore the association between intergenerational continuity of adverse childhood experiences (ACEs) and preschoolers’ cognitive performance to provide evidence for promoting healthy cognitive development in preschoolers. Methods A total of 450 children aged 3-6 years from 9 kindergartens in the rural area of Wuhu, Anhui Province were selected to enter the survey on cognitive development. The Childhood Trauma Questionnaire Short Form (CTQ-SF) and an investigator-designed questionnaire were employed to measure maternal ACEs and children ACEs, respectively. The Chinese version of the Wechsler Preschool and Primary Scale of Intelligence, Fourth edition (WPPSI-IV) was conducted to assess participants’cognitive performance. Results The detection rate was 26.7% for neither maternal nor child ACEs exposure, 18.9% for only maternal ACEs exposure, 31.6% for only child ACEs exposure, and 22.9% for both maternal and child ACEs exposure (intergenerational continuity of ACEs). Compared to children in neither maternal nor child ACEs exposure group, cognitive performance was significantly worse in children with intergenerational continuity of ACEs (103.92±10.00 vs 100.94±10.01, P=0.001). After adjusting for covariates, linear regression models showed that intergenerational continuation of ACEs was significantly associated with a 3.34-point reduction in offspring cognitive performance (95% CI: -6.54~-0.14, P=0.04). Conclusion Intergenerational continuity of ACEs is associated with cognitive impairment in preschoolers.
