Predicting an Alcohol Use Disorder in Urban American Indian Youth

Area of Science:

• Psychiatry
• Public Health
• Developmental Psychology

Background:

• Alcohol use disorders (AUDs) represent a significant public health concern, particularly among vulnerable populations.
• Understanding the developmental trajectories and predictors of AUDs is crucial for effective prevention and intervention strategies.
• American Indian youth face unique cultural and socioeconomic factors that may influence substance use patterns.

Purpose of the Study:

• To identify predictors of alcohol use disorders (AUDs) in an urban American Indian cohort.
• To examine the influence of behavioral, familial, and early substance use factors on AUD development.
• To investigate the role of parental alcoholism in the development of AUDs in offspring.

Main Methods:

• Longitudinal study following an urban American Indian cohort from age 11 to 20.
• Assessment of externalizing and internalizing behaviors, family conflict, and school liking.
• Diagnosis of lifetime alcohol abuse or dependence using established criteria.
• Statistical analysis to determine significant predictors and mediation effects.

Main Results:

• Approximately 27% of the cohort developed a lifetime AUD.
• Externalizing behaviors, family conflict, and lower school liking significantly predicted AUD.
• Neither maternal nor paternal alcoholism was a significant predictor of AUD in this sample.
• Early alcohol initiation was a substantial predictor of AUD and acted as a partial mediator.

Conclusions:

• Externalizing behaviors, adverse family environment, and early substance use initiation are key predictors of AUDs in American Indian youth.
• Parental history of alcoholism may not be as strong a predictor as other psychosocial factors in this specific cohort.
• Interventions should focus on addressing behavioral issues, improving family dynamics, and delaying alcohol initiation.
