Analyzing the relationship between individual and cumulative score of adverse childhood experiences (ACEs) with self-reported mental health disorders in Chile.

BACKGROUND

Adverse Childhood Experiences (ACEs) are widely recognized as significant predictors of poor mental health in adulthood. Latin America presents several unique challenges regarding ACEs, such as higher prevalence of violence and income and political inequality. However, little is known about this issue from nationally representative samples in the region, particularly in Chile.

OBJECTIVE

This investigation examines the association between individual and cumulative ACE scores and seven self-reported mental health conditions (substance abuse, depression, PTSD, generalized anxiety, suicide ideation, non-suicidal self-harm, and learning disorders) in a representative Chilean urban sample.

METHODS

A representative urban sample of 2101 adult Chileans completed the International Adverse Childhood Experiences Questionnaire (ACE-IQ) and disclosed any prior mental health diagnoses.

RESULTS

Around 40 % of the sample had experienced four or more ACEs in their lifetime. For these individuals, the risk of reporting a mental health disorder was significantly higher. Several logistic regression analyses were conducted to address the associations between ACEs and the seven mental health conditions. Notably, sexual abuse, bullying, and exposure to collective violence were the ACEs most strongly associated with self-reported mental health issues. Additionally, a cumulative ACE score was found to be a significant predictor of having a previous mental health diagnosis.

CONCLUSIONS

We found a significant predictive association between exposure to collective violence and six out of the seven self-reported mental health disorders. Similarly, sexual abuse demonstrated an association with all mental health conditions. Finally, individuals who experienced four or more ACEs had a notably higher chance of reporting a previous mental health diagnosis. We recommend conducting further ACE research in Latin America due to its cultural and contextual singularities.
