Adverse childhood experiences and the substance use behaviors of Latinx youth.

Abstract Purpose Adverse childhood experiences (ACEs) are associated with substance use, how cultural factors influence this association for Latinx youth is unknown. This study uses longitudinal data to examine associations of cultural factors, ACEs and substance use among Latinx young adults. Methods Latinx youth (N = 1179) completed surveys from a longitudinal study at seven assessment points from 2005 to 2016; ACEs was assessed when participants were on average 21.6 and substance use 23.9 years. ACEs measured psychological, physical, and sexual abuse, parental violence, divorce, substance use, mental illness, and incarceration. A three-stage hierarchical ordinary least squares (alcohol use) and negative binomial regression models (problematic alcohol, marijuana and tobacco use) were estimated to evaluate the role of cultural factors (acculturation, enculturation and ethnic identity) and ACEs in shaping substance use behaviors. Results Controlling for cultural variables, ACEs sum (B = 0.03, p = .01), maltreatment (B = 0.16, p Conclusions Results suggest a predictive relationship between ACEs, and alcohol, marijuana and tobacco use, after accounting for cultural factors. Beyond acculturation, enculturation and ethnic identity, findings identify ACEs as a salient predictor of substance use among Latinx young adults.
