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

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 < .01), and household (B = 0.12, p = .03) subdomains predicted alcohol use. One additional increase in maltreatment (IRR=1.23, 95 % CI: 1.00, 1.53) predicted 23 % higher count of problematic alcohol use. Maltreatment (IRR=1.50, 95 % CI: 1.05, 2.13) and household (IRR=1.66, 95 % CI: 1.18, 2.32) subdomains predicted increased counts of marijuana use. Four or more ACEs predicted increased counts of tobacco use (IRR=1.49, 95 % CI: 1.08, 2.06) among Latinx young adults.

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.
