Adverse childhood experiences and cognitive disability in the 2019 United States behavioral risk factor surveillance system.

A growing number of studies have found associations between adverse childhood experiences (ACEs) and adult well-being, with disparities between subpopulations. Limited research exists about the association between ACEs and cognitive disability, and variations by race and ethnicity. This study reports a cross-sectional analysis of 2019 Behavioral Risk Factor Surveillance System (BRFSS) data (n = 93 692) conducted in 2021. Logistic regression models examined the association between ACEs and cognitive disability (as defined by serious difficulty concentrating, remembering or making decisions because of a physical, mental, or emotional condition) and whether the association varied by race and ethnicity, adjusting for demographics, (age, gender, marital status), socioeconomic factors (income and education), and perceived general health. Exposures to 1, 2, 3, and 4 or more ACEs were associated with elevated odds of cognitive disability; the association varied by race and ethnicity (p for interaction less than 0.05). In stratified analyses, ACEs were positively associated with cognitive disability among the American Indian/Alaskan Native group, though significant only among those reporting 4 ACEs or more (OR: 2.89; 95% CI 1.25, 6.66). A dose response was observed for Black, White and Hispanic groups though the association was larger among Hispanic respondents. The elevated odds of cognitive disability associated with ACEs warrant additional research to understand mechanisms underlying this relationship across racial and ethnic groups. Additionally, interventions to prevent cognitive disability may benefit from considering ACEs across all populations, particularly among those with highest prevalence.
