Insights
Adverse childhood experiences (ACEs) significantly increase the risk of multiple neurodevelopmental disorders (NDDs). Each additional ACE is linked to higher odds of developing two or more NDDs, highlighting the impact of cumulative adversity.
Area of Science:
- Child Health
- Neuroscience
- Psychiatry
Background:
- Adverse childhood experiences (ACEs) and neurodevelopmental disorders (NDDs) are prevalent in childhood.
- The cumulative impact of ACEs on the development of multiple NDDs is not well understood.
Purpose of the Study:
- To examine the association between cumulative ACEs and the presence of multiple NDDs in children.
- To investigate specific ACEs and NDD combinations linked to increased risk.
Main Methods:
- Utilized data from 120,629 children (aged 3-17) from the 2021-2023 US National Survey of Children's Health.
- Employed logistic regression, analyzing ACEs as continuous and categorical variables, adjusted for covariates.
- Assessed associations for common NDD combinations and individual ACEs.
Main Results:
- The prevalence of multiple NDDs increased with the number of ACEs, from 4.5% with 0 ACEs to 17.8% with ≥3 ACEs.
- Each additional ACE was associated with a 13% increased odds of multiple NDDs (aOR=1.13).
- Specific ACEs like mistreatment, household mental illness, and economic hardship showed significant associations with multiple NDDs.
Conclusions:
- Cumulative ACEs are significantly associated with a higher likelihood of developing multiple NDDs.
- Findings underscore the need for coordinated health policies and services addressing cumulative adversity in children.
- Future research should focus on integrated approaches to support children with multiple NDDs and a history of ACEs.
Abstract:
Adverse childhood experiences (ACEs) and neurodevelopmental disorders (NDDs) are frequent yet the relationship between cumulative ACEs and multiple NDDs remains poorly understood. Using data from 120,629 children aged 3-17 years in the 2021-2023 US National Survey of Children's Health, we examined associations between ACEs and multiple NDDs, defined as the presence of ≥ 2 NDDs. Logistic regression, adjusted for sociodemographic and health covariates, estimated associations for ACEs treated as a continuous variable and as categorical groups (0, 1, 2, and ≥ 3 ACEs). We also assessed associations for common NDD combinations and individual ACE. The prevalence of multiple NDDs increased with the number of ACEs: 4.5% (95% confidence interval [CI]: 4.2-4.8) for 0 ACE, 8.4% (95% CI: 7.7-9.1) for 1 ACE, 11.9% (95% CI: 10.7-13.2) for 2 ACEs, and 17.8% (95% CI: 16.5-19.2) for ≥ 3 ACEs. Each additional ACE was associated with 13% higher odds of multiple NDDs (adjusted odds ratio [aOR] = 1.13, 95% CI: 1.09-1.17). Compared with no ACE, the odds of multiple NDDs were higher for 1 ACE (aOR = 1.48, 95% CI: 1.30-1.68), 2 ACEs (aOR = 1.78, 95% CI: 1.52-2.09), and ≥ 3 ACEs (aOR = 1.91, 95% CI: 1.62-2.26). Associations were consistent across three NDD combinations. Individually, health- or disability-related mistreatment, household mental illness, and economic hardship showed significant associations. Cumulative ACEs are associated with a greater likelihood of multiple NDDs, suggesting future research, health policy, system and service planning require coordinated responses that account for the diverse adversities experienced by many families and children.
