Trends in prevalence of adverse childhood experiences by sociodemographic factors in the United States: Behavioral Risk Factor Surveillance System 2009–2022.

Background: Limited data exists on trends in prevalence of adverse childhood experiences (ACE) at the national level and sociodemographic correlates of having ACEs. This study examined trends in ACE prevalence and sociodemographic correlates in US adults over 14 years using nationally representative data. Methods: Data on 447,162 adults from the Behavioral Risk Factor Surveillance System (BRFSS) across four timepoints (2009–2010; 2011–2012; 2019–2020; 2021–2022) was analyzed and weighted for population estimates. The primary outcome was ACEs with 3 groups used (0 vs. 1 + ACEs; <4 vs. 4 + ACEs; 0 vs. 1 vs. 2 vs. 3 vs. 4 + ACEs). Sociodemographic factors included age, sex, race/ethnicity, employment, education, marital status, income and insurance status. Prevalence trends were examined by estimating prevalence of ACE groupings (0/1+; <4/4+; 0,1,2,3,4+) across the four timepoints and trend analysis was performed to determine if the differences over time were statistically significant. Unadjusted and adjusted prevalence ratios were estimated using log-binomial regression models with ACE groupings as the outcome and timepoints as the primary independent variable with sociodemographic factors as covariates. Results: Across the four time points, prevalence of ACEs was higher across groupings of ACEs by time. For ACEs 1+, prevalence was 62.2% (2009–2010); 62.2% (2011–2012); 64.5% (2019–2020); and 67.2% (2021–2022). For ACEs 4+, prevalence was 17.4% (2009–2010); 18.1% (2011–2012); 20.4% (2019–2020); and 22.6% (2021–2022). Prevalence of ACE 1 + was higher for older adults, Non-Hispanic Black adults, Non-Hispanic Other adults, and those with higher education. Prevalence of 4 + ACEs was higher for females, and lower for those with higher education and those with higher annual incomes. Conclusion: This study shows an increased prevalence of having ACEs over a 14-year period and identified independent sociodemographic correlates of having ACEs in a nationally representative study. Targeted interventions are needed to reduce burden of ACEs using population-based approaches. [ABSTRACT FROM AUTHOR]
